“…The option of this service for the use of the pulmonary homograft, in such position, is based on studies that show that the aortic homograft in pulmonary position presents higher index of calcification due to its composition rich in elastin [4][5][6][7][8][9][10][11][12][13][14][15] .…”

“…From the surgical point of view, the pulmonary homograft is available in small sizes, has higher hemostatic capacity, higher ductility and handling easiness for the surgeon, their branches can be used for enlarging the stenotic areas in the pulmonary arteries, does not need chronic anticoagulation, presents higher resistance to endocarditis and has a potential feasibility for the second repair 5,7,10,11,[15][16][17][18] .…”

“…In young people, the insertion of the homograft it is considered a risk factor for the conduit failure 4,5,8,9,12,14,15,[18][19][20][21] . The reasons for this are diverse and, among them, the accelerated growth pattern of the children, the use of homografts of smaller sizes and the immunological response exacerbate in the children.…”

“…Zmiany degeneracyjne zachodzą szybciej w homograftach aortalnych niż w płuc-nych, a procesy wapnienia są bardziej nasilone [8,9]. Podjęto próbę przeznaczyniowego wszczepienia zastawki płuc-nej u pacjenta z bardzo zwapniałym homograftem, który -patrząc na obraz radiologiczny oraz retrospektywnie po usunięciu operacyjnym -można nazwać analogicznie do porcelanowej aorty "porcelanowym" homograftem aortalnym.…”

S t r e s z c z e n i ePrzeznaczyniowa implantacja zastawki płucnej jest nową metodą leczenia chorych ze złożonymi wrodzonymi wadami serca, u których po operacyjnej rekonstrukcji drogi odpływu prawej komory doszło do zwężenia lub niedomykalności zastawki pnia płucnego. Najlepszymi kandydatami do zabiegu są chorzy z homograftem płucnym lub innym pełnym konduitem w drodze odpływu prawej komory. W pracy opisano pacjenta po rekonstrukcji drogi odpływu prawej komory za pomocą homograftu aortalnego, u którego wystąpiło powikłanie w trakcie zabiegu nieoperacyjnego wszczepienia zastawki płucnej.Słowa kluczowe: przeznaczyniowe wszczepienie zastawki, zastawka płucna, homograft aortalny, płucny, pęknięcie homograftu A b s t r a c t A male patient had a repeat surgical right ventricular outflow reconstruction with the aortic homograft, for pulmonary atresia at the age of 7 years. At the age of 17 a homograft dysfunction (with predominant stenosis) developed and he was admitted for transcatheter pulmonary valve implantation. Severe calcifications of the total homograft wall were recognized. A homograft rupture with contrast extravasation to the mediastinal space occurred at the superior margin of the stent implanted for valve presenting. A covered stent was implanted to cover the leak, but this resulted in a second homograft rupture at the distal margin of the stent. The extravasation was estimated to be small and stable, and a Melody pulmonary valve was successfully implanted on a 20 mm system. Repeat planned angiography 4 days after the procedure revealed significant enlargement of the pseudoaneurysm and the patient was sent for surgery. Right ventricular outflow was uneventfully reconstructed with a pulmonary homograft. Excised old aortic homograft walls had an eggshell appearance. We suggest that a "porcelain" aortic homograft should be a contraindication for transcatheter pulmonary valve implantation.

Cryopreserved homograft valves in the pulmonary position: Risk analysis for intermediate-term failure

Abstract: Homograft valves function satisfactorily in the pulmonary position at mid-term follow-up. The pulmonary homograft valve appears to be more durable than the aortic homograft valve in the pulmonary position.
