Tetralogia fallota
Epidemiologia

Tetralogia Fallota (TF) jest najczęstszą siniczą wrodzoną wadą serca, stanowiącą 5-10% wszystkich CHD, z częstością występowania 3-6 na 10 000 żywych urodzeń (ok. 1 na 2 000-3 600). Występuje zróżnicowanie geograficzne, z wyższą częstością w Afryce Subsaharyjskiej (do 16,9% w Nigerii) i niższą w krajach zachodnich. Wada częściej dotyka mężczyzn, choć różnice płciowe są niewielkie. Większość przypadków jest sporadyczna, z ryzykiem wystąpienia u rodzeństwa 1-5%. TF często współistnieje z anomaliami pozasercowymi (15%) i zespołami genetycznymi, takimi jak zespół Downa, DiGeorge’a (delecja 22q11.2), Alagille’a, VACTERL czy CHARGE. Diagnostyka prenatalna i przesiewowa pulsoksymetria noworodków umożliwiają wczesne wykrycie wady.

Epidemiologia Tetralogii Fallota

Tetralogia Fallota stanowi najczęstszą formę siniczej wrodzonej wady serca, reprezentując około 5-10% wszystkich wrodzonych wad serca (CHD). Częstość występowania tej wady szacuje się na 3-6 przypadków na 10 000 żywych urodzeń, co daje około 1 przypadek na 2 000-3 600 żywych urodzeń123. Dokładne szacunki mogą się różnić w zależności od regionu geograficznego i metod badawczych, przy czym niektóre źródła podają częstość występowania nawet 1 na 2 077 urodzeń w Stanach Zjednoczonych4.

Występowanie geograficzne

Występowanie Tetralogii Fallota wykazuje znaczące różnice geograficzne. W Stanach Zjednoczonych szacuje się, że co roku rodzi się około 1 660-1 768 dzieci z tą wadą45. Natomiast w krajach Afryki Subsaharyjskiej odnotowuje się wyższy odsetek przypadków w porównaniu z globalnymi szacunkami, średnio 10% (95% CI: 9%-12%) wszystkich wrodzonych wad serca, z najwyższą częstością w regionie południowym (14%, 95% CI: 7%-21%)67. W Nigerii szczególnie zaobserwowano wysoką częstość występowania – 16,9% wśród wszystkich przypadków wrodzonych wad serca8.

W Hiszpanii przeprowadzono badanie na przestrzeni 36 lat (1981-2016), które wykazało 1 035 zgonów związanych z Tetralogią Fallota, z wyższym wskaźnikiem umieralności w południowych regionach kraju9. W badaniu przeprowadzonym w Kolumbii, lokalna częstość występowania została oszacowana na 2,21 przypadków (CI 1,85-2,61) na 10 000 żywych urodzeń10.

Rozkład płci

Choć początkowo uważano, że Tetralogia Fallota występuje równie często u obu płci, nowsze badania sugerują nieznaczną przewagę u płci męskiej31112. Jednakże, niektóre źródła nadal wskazują na równy rozkład płci wśród pacjentów11314. W populacji dorosłych pacjentów po korekcji wady, obie płcie wydają się być równomiernie dotknięte objawami związanymi z wiekiem15.

Powiązania genetyczne i zespoły współistniejące

Większość przypadków Tetralogii Fallota występuje sporadycznie i nie ma charakteru rodzinnego. Ryzyko wystąpienia wady u rodzeństwa pacjentów szacuje się na 1-5%1612. Wada ta jest często powiązana z anomaliami pozasercowymi, które występują w około 15% przypadków17.

Genetycznie, Tetralogia Fallota najczęściej wiąże się z zespołem Downa oraz zespołem DiGeorge’a11. Badania genetyczne wykazały, że u niektórych pacjentów może występować delecja 22q11.2 i inne submikroskopowe zmiany liczby kopii3. Inne powiązane stany obejmują zespół Alagille’a, zespół VACTERL oraz zespół CHARGE18.

Dodatkowo, Tetralogia Fallota może być powiązana z płodowym zespołem alkoholowym, zespołem fenyloketonurii matczynej i płodowym zespołem hydantoinowym1914.

Przeżywalność i długoterminowe rokowanie

Dzięki znaczącym postępom w leczeniu chirurgicznym i opiece medycznej, przeżywalność pacjentów z Tetralogią Fallota znacznie się poprawiła w ostatnich dekadach20. Według aktualnych danych, po korekcji wady ponad 85-90% pacjentów dożywa wieku dorosłego2122. Współczesne wskaźniki przeżycia 30-letniego wahają się od 68,5% do 90,5%15, a średnia przeżywalność wynosi 94% u pacjentów w wieku 16 lat i starszych, którzy przeszli naprawę chirurgiczną15.

Dla porównania, bez interwencji chirurgicznej wskaźniki przeżycia drastycznie maleją wraz z wiekiem pacjenta. Szacuje się, że pacjenci z nieoperowaną Tetralogią Fallota mają następujące wskaźniki przeżycia1:

  • 66% w wieku 1 roku
  • 40% w wieku 3 lat
  • 11% w wieku 20 lat
  • 6% w wieku 30 lat
  • 3% w wieku 40 lat

1

Niektóre źródła podają jeszcze niższe wskaźniki: bez naprawy, tylko 1 na 3 pacjentów dożywa wieku 10 lat23. Dane z ery przedchirurgicznej wskazują na 50% przeżywalność do 3 roku życia i 25% do 10 roku życia24.

Wyniki współczesnego leczenia

W obecnej erze, śmiertelność okołooperacyjna przy całkowitej naprawie wady jest bardzo niska i wynosi około 1-5% dla niepowikłanej Tetralogii Fallota2526. Niektóre ośrodki specjalistyczne, jak Texas Children’s Heart Center, raportują wskaźniki przeżycia sięgające prawie 99% przy średnio 30 zabiegach naprawczych Tetralogii Fallota rocznie27.

Długoterminowe przeżycie po naprawie Tetralogii Fallota jest bardzo dobre, a większość pacjentów, którzy przechodzą naprawę, żyje jeszcze 30 lat później23. Szacowana 30-letnia przeżywalność sięga nawet 91% w obecnej erze medycyny28.

Znaczenie nadzoru i monitorowania

Poza zwiększoną przeżywalnością, systematyczny nadzór i monitorowanie pacjentów z Tetralogią Fallota mają kluczowe znaczenie dla długoterminowych wyników leczenia29. Wada ta może być wykryta już w okresie prenatalnym podczas badania ultrasonograficznego1630 lub po urodzeniu za pomocą przesiewowego badania pulsoksymetrii u noworodków4.

Długoterminowa opieka

Wszyscy pacjenci po korekcji Tetralogii Fallota wymagają dożywotniej, regularnej kontroli kardiologicznej w celu monitorowania potencjalnych powikłań, takich jak2831:

  • Dysfunkcja zastawki płucnej
  • Zaburzenia rytmu serca (arytmie)
  • Nietolerancja wysiłku
  • Zmniejszona funkcja prawej komory

3128

Wielomodalne badania są zalecane okresowo, a ich częstotliwość jest dostosowywana do objawów i ciężkości choroby20. To podejście umożliwia wczesne wykrycie i proaktywne zarządzanie komplikacjami.

Szczególnie istotny jest fakt, że dzieci z Tetralogią Fallota mogą wymagać dodatkowych operacji lub cewnikowania w miarę dorastania. Chociaż celem początkowej operacji jest zapewnienie najlepszego długoterminowego przepływu do płuc, u niektórych dzieci może rozwinąć się nieszczelność zastawki płucnej wymagająca wymiany w przyszłości, co często następuje w okresie dojrzewania lub wczesnej dorosłości32.

Wyzwania w krajach rozwijających się

W krajach Afryki Subsaharyjskiej i innych regionach rozwijających się, nadzór nad Tetralogią Fallota napotyka na dodatkowe wyzwania. W wielu krajach brakuje systematycznych badań przesiewowych, co prowadzi do późnego lub przypadkowego rozpoznania wady, często już z powikłaniami33. W Arabii Saudyjskiej, na przykład, zidentyfikowano znaczące braki w dostępie do ośrodków badających wrodzone wady serca poza regionem stołecznym (Rijad)34.

Znaczne różnice w rozpowszechnieniu Tetralogii Fallota między regionami podkreślają złożone oddziaływanie czynników wpływających na występowanie tej wady35. Zrozumienie prawdziwego zakresu obciążenia Tetralogią Fallota może pomóc decydentom i świadczeniodawcom w ustalaniu priorytetów interwencji, optymalizacji alokacji zasobów i potencjalnej poprawie wyników leczenia35.

Znaczenie dla zdrowia publicznego

Wrodzone wady serca, w tym Tetralogia Fallota, stanowią istotny problem zdrowia publicznego. W Stanach Zjednoczonych 1 na 33 niemowlęta rodzi się ze strukturalną wadą wrodzoną36. Postępy medyczne i chirurgiczne pozwoliły na zwiększenie częstości występowania wrodzonych wad serca wśród starszych dzieci i dorosłych, z szacowaną populacją dorosłych pacjentów z wrodzonymi wadami serca w USA wynoszącą około 1 milion, z czego szacunkowo 15% to pacjenci z Tetralogią Fallota1.

Dążenie do dokładnego określenia epidemiologii Tetralogii Fallota jest podstawą, na której będą opierać się wysiłki badawcze mające na celu identyfikację przyczyn dysmorfogenezy sercowej i stworzenie możliwości ich zapobiegania34. Pomimo znaczących postępów w dziedzinie diagnostyki molekularnej wrodzonych wad serca, pierwotne badania populacyjne dostarczające szczegółowej wiedzy na temat częstości występowania, powiązanych malformacji oraz odpowiedniego poradnictwa dla pacjentów i rodzin pozostają nieocenione dla arsenału i bazy wiedzy kardiologów dziecięcych37.

Wczesna diagnoza i odpowiednie leczenie chirurgiczne pozwalają pacjentom z Tetralogią Fallota prowadzić stosunkowo normalne życie, choć będą potrzebować regularnej opieki medycznej przez całe życie i mogą mieć ograniczenia dotyczące wysiłku fizycznego33.

Standaryzacja opieki

Standaryzacja dożywotniej opieki pooperacyjnej jest niezbędna do optymalnego planowania kolejnych interwencji, w tym diagnostyki obrazowej29. Celem grupy roboczej ACC ACPC ds. jakości jest dostarczenie narzędzi praktyki klinicznej dla świadczeniodawców kardiologicznych, ostatecznie w celu zmniejszenia zmienności praktyki w chorobach wrodzonych serca29.

Dorosłym pacjentom z Tetralogią Fallota zaleca się kontynuowanie opieki u specjalisty ds. wrodzonych wad serca dorosłych w celu regularnego monitorowania23. Wybór odpowiedniego lekarza i programu ACHD do zarządzania wrodzoną wadą serca u dorosłych ma kluczowe znaczenie38.

Zapotrzebowanie na skrupulatny, dożywotni nadzór nie może być dość podkreślone, aby można było optymalnie zaplanować czas wszelkich potencjalnych kolejnych interwencji25.

    Tetralogy of Fallot (TOF) is the most frequent cyanotic congenital heart defect. TOF mortality has fallen remarkably in recent years due to therapeutic advances. […] A total of 1035 deaths were attributed to TOF (57.78% of them were men and 42.22% were women). […] In terms of geographical analysis, some areas with a significantly higher risk of TOF mortality were identified in the south of Spain, though no specific spatial pattern was in evidence. […] The decrease in TOF mortality may be related to improvements in diagnostic and treatment techniques. […] A total of 1035 TOF-related deaths were identified in Spain during the period 1981-2016 (631 from 1981 to 1998, and 404 from 1999 to 2016), 57.78% of which were males (598 males vs. 437 females). […] In terms of geographical analysis, while some provinces show a lower-than-expected risk, a series of significantly higher-than-expected risks of TOF-related mortality were observed in some demarcations, mostly in southern Spain.

    Tetralogy of Fallot affects about five of every 10,000 babies and occurs equally in boys and in girls. It is one of the most common congenital abnormalities of the heart that requires intervention in the first year of life. […] Maternal abuse of alcohol during pregnancy, leading to fetal alcohol syndrome, is linked to tetralogy of Fallot. Mothers who take medications to control seizures and mothers with phenylketonuria are also more likely to have a baby with tetralogy of Fallot. […] The amount of oxygen-poor (blue) blood that passes through the VSD to the left side of the heart varies. If the right ventricle obstruction is severe, or if the pressure in the lungs is high, a large amount of oxygen-poor (blue) blood passes through the VSD, mixes with the oxygen-rich (red) blood in the left ventricle and is pumped to the body.

  • #23 Tetralogy of Fallot (ToF): Symptoms, Causes & Treatment
    https://my.clevelandclinic.org/health/diseases/22343-tetralogy-of-fallot
    Tetralogy of Fallot is a congenital heart condition, which means its present at birth. This condition is rare. One out of 2,077 babies born in the U.S. each year has tetralogy of Fallot. But its one of the more common congenital heart disorders. Tetralogy of Fallot tends to happen more often in male babies. Healthcare providers also see ToF often in babies who have Down syndrome or other chromosome disorders. […] Your healthcare provider can diagnose tetralogy of Fallot during pregnancy or after your baby is born. They usually find ToF in the first few weeks or months of life. […] Many adults who undergo repair for a ToF heart defect dont need further surgical treatment. But they should continue to follow up with an adult congenital heart disease specialist for regular monitoring. […] With medical advances, the outlook for babies with tetralogy of Fallot is better than it was in the past. Surgical treatment is very effective in correcting structural defects and blood flow through the heart. Long-term survival after ToF repair is very good. Most people who undergo repair are alive 30 years later. Without a repair, 1 out of 3 people with tetralogy of Fallot live to age 10. […] Your baby needs lifelong care for congenital heart disorders like tetralogy of Fallot.
  • #24 Tetralogy of Fallot | Pediatric Echocardiography
    https://pedecho.org/library/chd/tetralogy-fallot
    Tetralogy of Fallot (TOF) is the most common form of cyanotic congenital heart disease. It comprises approximately 3.5% of infants born with congenital heart disease and 8-10% of cyanotic cases. Worldwide reported prevalence of TOF is 0.28 per 1,000 live births. There is no gender predilection. […] In the current era, TOF is repaired during infancy with an excellent prognosis. Life expectancy for unrepaired TOF is low, historically cited as 50% by 3 years of age and 25% by 10 years.
  • #25 Tetralogy of Fallot – Symptoms and causes – Mayo Clinic
    https://www.mayoclinic.org/diseases-conditions/tetralogy-of-fallot/symptoms-causes/syc-20353477
    Tetralogy of Fallot is usually diagnosed during pregnancy or soon after a baby is born. […] The need for diligent lifelong surveillance cannot be overemphasized, so that proper timing of any potential subsequent interventions can be optimized. […] In the modern era, repair of tetralogy of Fallot can be performed with very low mortality, in the neighborhood of 1%, and the late survival and quality of life are excellent for the majority of patients. […] Mayo Clinic has a long-standing history in the surgical care of tetralogy of Fallot since the earliest days of cardiac surgery in the mid 1950s.

  • #27 Tetralogy of Fallot | Texas Children’s
    https://www.texaschildrens.org/content/conditions/tetralogy-fallot
    Tetralogy of Fallot is rare, occurring in approximately 5 out of every 10,000 babies. […] The cause of the condition is typically unknown. It may be more common with certain chromosomal abnormalities such as Down’s or DiGeorge’s syndromes, or in women who contract certain infections during pregnancy, such as rubella. […] Heredity may also play a role, with those born with tetralogy of Fallot more likely to have a child with the condition. […] The Congenital Heart Surgery Division at Texas Children’s Heart Center performs an average of 30 tetralogy of Fallot repairs each year with a survival rate of nearly 99%.
  • #28 Tetralogy of Fallot in adults
    https://www1.racgp.org.au/ajgp/2024/july/tetralogy-of-fallot-in-adults
    Following surgical repair of tetralogy of Fallot, it is important to have lifelong surveillance in adulthood for complications such as pulmonary valve dysfunction. […] An increasing number of children born with congenital heart disease are surviving into adulthood in the modern era. Tetralogy of Fallot (TOF) is one such congenital cardiac anomaly. […] The estimated 30-year survival is up to 91% in the current era. […] All patients should have lifetime follow-up with a congenital heart disease specialist aiming to identify and manage long-term complications. […] These patients require lifelong follow-up for early identification of complications, and this should be in conjunction with an adult congenital heart disease unit.

    Tetralogy of Fallot is the most common cyanotic congenital heart disease and requires surgical repair. […] Standardized lifelong postrepair surveillance is necessary to guide optimal timing of subsequent interventions, including diagnostic imaging. […] Follow-up and management of patients with repaired TOF is primarily dictated by degree of residual lesions, including residual PS, resultant pulmonary regurgitation (PR), or residual VSD. Patients with repaired TOF require lifelong periodic surveillance testing even if residual lesions are minimal and without symptoms, as intervention is often recommended before development of symptoms. […] The goal of the ACC ACPC Quality Working Group is to provide clinical practice tools for cardiology providers, ultimately to reduce practice variability in CHD.
  • #30 Tetralogy of Fallot (TOF) | Boston Children’s Hospital
    https://www.childrenshospital.org/conditions/tetralogy-fallot
    Tetralogy of Fallot (TOF) is a serious congenital heart defect affecting about two in 10,000 babies. […] Most cases of TOF have no genetic association. However, there are some cases with a genetic link. Parents who already have a child with a congenital heart defect are slightly more likely to have a second child with a heart defect. Boston Childrens Hospital maintains a Tetralogy of Fallot Genetics Registry that is exploring possible causative genes. […] Tetralogy of Fallot can be detected during an ultrasound exam during pregnancy. If your clinical team suspects your baby may have TOF, they will order a fetal echocardiogram (cardiac ultrasound) to further evaluate the structure of the heart and how it’s functioning with this condition. […] Almost all children with tetralogy of Fallot will need surgery. Many children can be treated medically until a complete repair can be done. More severe forms of TOF may require early intervention, including hospitalization.
  • #31 Tetralogy of Fallot – Pediatric Cardiology | Northwell Health
    https://pediatrics.northwell.edu/departments-services/pediatric-cardiology/find-care/conditions/tetralogy-of-fallot
    ToF is a complex form of congenital heart disease that changes the normal flow of blood through the heart. […] Most children after repair of tetralogy of Fallot should do very well, but they will need lifelong surveillance by a cardiologist to monitor for problems such as heart rhythm problems (arrhythmia), valve leakage, exercise intolerance and reduced right ventricular function. […] Periodic assessment is necessary to assess the health of the right ventricle.
  • #32 Tetralogy of Fallot (TOF) | Boston Children’s Hospital
    https://www.childrenshospital.org/conditions/tetralogy-fallot
    Children with tetralogy of Fallot may need additional operations or catheterizations as they grow older. Although the goal of the initial operation is to provide the best long-term flow to the lungs, some children develop leakage from the lung valve, requiring replacement in the future. This often occurs in adolescence or early adulthood, although it can happen sooner. […] Our team in the Boston Childrens Benderson Family Heart Center treats some of the most complex pediatric heart conditions in the world, with excellent results. Adults who were treated for congenital heart disease as children will need to be followed by a cardiologist because complications from early heart disease can arise in adulthood. The Boston Adult Congenital Heart Program (BACH) is a world leader in the care of this unique patient population.

    https://www.itmedicalteam.pl/articles/tetralogy-of-fallot-in-four-down-syndrome-patients-in-setif-algeria-diagnosis-and-clinical-aspects-106081.html
    Tetralogy of Fallot (TOF) is the most common form of cyanotic congenital heart disease. And represents 75% in the general population. However, its association with down syndrome is infrequent. […] The TF represents according to the statistics 5%-8% of all CHDs in T21. […] In the absence of systematic screening of CHD in the DS in our country, our patients are discovered with pulmonary regurgitation, a frequent late or accidental consequence or in an incidental finding. […] Operative or catheter interventional therapy for these patients may be more complex than if the problem had been addressed in early and may have to be combined with complications. […] With early diagnosis followed by appropriate surgical treatment, our patients who have tetralogy of Fallot live relatively normal lives, though they’ll need regular medical care throughout life and might have restrictions on exercise. […] Anticipation of and early implementation of prevention and treatment measures may help to reduce these post-operative morbidities in patients with Down syndrome undergoing congenital heart surgery.

    The epidemiology of congenital heart disease in Saudi Arabia has not been determined, nor has it received the attention it warrants. […] Knowledge of the epidemiology of congenital heart disease is the basis on which investigative efforts will emerge to identify the causes of cardiac dysmorphogenesis and afford opportunities to prevent them. […] The cumulative detection rate at 1 year of age for all lesions was 59%. […] The impressive network of health institutions in Saudi Arabia should be exploited to give a better future for children with congenital heart disease. […] Only 60% of 3786 children referred with suspected heart disease had a congenital heart condition. […] The availability of paediatric cardiac services in 3 centres within the same region (Riyadh) and an almost complete absence of cardiac centres which investigate congenital heart disease in other regions is a major deficiency which deserves urgent attention from policy makers in Saudi Arabia.
