Tetralogy Of Fallot Repair

Several techniques designed to improve long-term results after repair of tetralogy of Fallot are described. We have recently embarked on a program focused on preserving the native pulmonary valve. Here, combined techniques are described in detail, including intraoperative pulmonary valve balloon dilatation, pulmonary valve reconstruction by delamination and resuspension of the leaflets, and pulmonary valve annulus augmentation. As with any other complex congenital heart disease, senior surgeons should select teaching cases, starting from the less severe side of the spectrum.

Pulmonary Valve Replacement

Abstract OBJECTIVES Chronic pulmonary valve (PV) regurgitation is a common late sequela after repair of congenital heart diseases like tetralogy of Fallot or pulmonary stenosis, leading to right ventricular dilatation and failure and increased late morbidity and mortality. Timely reoperation may lead to a complete right ventricular recovery. An injectable PV allows pulmonary valve replacement, with or without cardiopulmonary bypass, under direct observation, thereby minimizing the impact of surgery on cardiac function. The aim of this study was to evaluate the feasibility and mid- to long-term clinical outcomes with this device. METHODS From April 2007 to October 2019, a total of 85 symptomatic patients with severe pulmonary regurgitation or pulmonary stenosis underwent pulmonary valve replacement with an injectable stented pulmonary prosthesis. Data were collected from the international proctoring registry. Mean patient age was 26.7 years. The underlying diagnosis was repaired tetralogy of Fallot in 69.4% patients; moderate or severe pulmonary regurgitation was present in 72.9%. All patients had echocardiographic scans before the operation and during the follow-up period. A total of 54.1% patients also had preoperative/postoperative cardiac magnetic resonance imaging (MRI) or catheterization; 25.9% had off-pump implants. In 53% patients, pulmonary valve replacement was associated with the repair of other cardiac defects. RESULTS Minor postoperative complications were observed in 10.8% patients. The overall mortality rate was 2.3%; mortality after valve replacement was linked to a severe cardiac insufficiency and it was not related to a prosthesis failure; 1 prosthesis was explanted from 1 patient because of endocarditis, and 6% of patients developed PV stenosis; minor complications occurred in 4.8%. The mean follow-up period was 4.8 years (2 months–12.7 years); 42% of the patients were followed for more than 5 years. Follow-up echocardiography and cardiac MRI showed a significant reduction in RV size and low gradients across the PV. CONCLUSIONS An injectable PV may be implanted without cardiopulmonary bypass and in a hybrid operating theatre with minimal surgical impact. The bioprosthesis, available up to large sizes, has a low profile, laminar flow and no risk of coronary artery compression. Incidence of endocarditis is rare. The lack of a suture ring permits the implant of a relatively larger prosthesis, thereby avoiding a right ventricular outflow tract obstruction. This device permits future percutaneous valve-in-valve procedures, if needed. Results concerning durability are encouraging, and mid- to long-term haemodynamic performance is excellent.

The Mean

Background: Late pulmonary valve replacement following repair of tetralogy of Fallot may become necessary in patients with chronic pulmonary insufficiency. There is limited information on the long-term outcome of these prostheses, which is the focus of this study. Methods: We conducted a retrospective study of patients with repaired tetralogy of Fallot who underwent pulmonary valve replacement from 1990 to 2015 in our institution. We investigated imaging and clinical parameters including mortality and late adverse events (reintervention [surgical or transcatheter]), infective endocarditis, or arrhythmias requiring device implantation or ablation. Results: There were 69 patients divided into 3 groups: Carpentier-Edwards (n = 14), Contegra (n = 40), and pulmonary homograft (n = 15). The mean age at the time of pulmonary valve replacement was 21 ± 12 years. The mean follow-up was 8.5 ± 4.7 years. The mean preoperative and postoperative right ventricular end-diastolic volume index was 210 ± 42 and 120 ± 24 mL/m2, respectively. There were no mortalities. Late adverse events were observed in 23 (33%) patients: 15 (22%) reintervention (surgical or transcatheter), 11 (16%) endocarditis, and 11 (16%) arrhythmias. Overall, 1-, 5-, and 10-year freedom from surgical reintervention was 98.5%, 93.6%, and 79.3%, respectively. The Contegra group had significantly higher pulmonary valve gradients, a higher risk of developing late adverse events compared to Carpentier-Edwards ( P = .046) and pulmonary homograft ( P = .055) in multivariate analysis and increased risk for reintervention in the univariate analysis (hazard ratio: 3.4; 95% CI: 0.92-13; P value.066). Conclusion: Pulmonary valve replacement in patients with repaired tetralogy of Fallot has acceptable short- and intermediate-term outcomes. Contegra prosthesis had a higher risk of late adverse events with higher pulmonary valve gradients.

Tetralogy Of Fallot Repair

A Fallot-tetralógia miatti műtétet követően a hosszú távú túlélést befolyásoló tényezők közé tartozik a kamrai tachycardia és a hirtelen szívhalál. E betegek gondozásában érdemi segítséget jelent az implantálható cardioverter defibrillátor rendszer. A végleges pacemaker és/vagy implantálható cardioverter defibrillátor implantációját követően ritka, ám potenciálisan letális kimenetelű fertőzéses szövődmény az endocarditis. Ez esetben a leghatékonyabb kezelési mód a kombinált terápia, amely a beültetett készülék + elektródák teljes körű eltávolításából és agresszív antibiotikus kezelésből áll. Célkitűzés: Ilyen esetekben a tervezett reimplantáció különös óvatosságot igényel a nagyobb recidívaarány miatt, amelynek rizikója fokozottabb pacemakerdependencia esetén. Célunk olyan módszer alkalmazása volt, amelynek segítségével a recidíva kockázata minimálisra csökkenthető. Módszer: Esetünkben a korábban Fallot-tetralógia miatt többször műtött, pacemaker-, majd implantálható cardioverter defibrillátor beültetéseken átesett betegnél recidív endocarditis miatt készülék- és elektródaeltávolítást végeztünk, standard antibiotikus terápia alkalmazásával. A reimplantációt minithoracotomián keresztül végeztük. Az így elhelyezett sokkelektróda elégtelen működése miatt egy másik sokkelektródát szubkután vezettünk a hátsó mellkasfali régióba; rendszerünk az indukált kamrafibrillációt sikerrel szüntette meg. Megbeszélés: Esetismertetésünk demonstrálja a szubkután defibrillátorrendszer alkalmazhatóságát és előnyeit speciális körülmények fennállásakor. Felhívjuk a figyelmet arra a tényre, hogy ezt a technikát gyakrabban is lehetne alkalmazni olyan esetekben, amelyekben a transzvénás implantáció nem optimális.
