Homografts, bovine jugular vein conduits and porcine-valved Dacron conduits exhibit equal durability after implantation in patients below 1 year of age independent of their size. Nonetheless, moderate conduit stenosis or insufficiency develops earlier in patients with a Contegra conduit. Conduit placement in the neonatal period and implantation in a heterotopic position shortens the durability.
Following ALCAPA repair, LV function significantly improved, regardless of age at the time of repair. In addition, preoperative functional MV regurgitation decreased over time. Concomitant mitral valve surgery at the time of ALCAPA repair is required in patients with structural abnormalities of the MV.
Cyanotic and very young children with complete atrioventricular septal defect combined with the tetralogy of Fallot who require urgent treatment have long-term outcomes after staged repair similar to those of patients who undergo primary repair. Preoperative atrioventricular valve regurgitation is associated with increased risk for reoperation over the long-term.
The patch material used for reconstruction of the aortic arch in HLHS influences the rate of recoarctation following the Norwood I procedure. Equine pericardium cannot be recommended.
The incidence of RVOTO after ASO is not negligible. Complex morphology, such as side-by-side great arteries and aortic arch anomalies influences the development of RVOTO.
Background: The dual-filter Sentinel™ Cerebral Protection System (Sentinel-CPS) is increasingly used during transcatheter aortic valve replacement (TAVR). However, complex vascular anatomy may challenge Sentinel-CPS deployment.Aim of the study: We sought to investigate the impact of anatomic features of the aortic arch and the supra-aortic arteries on technical device failure of Sentinel-CPS application.Methods: Analysis of the multislice computed tomography pre-TAVR aortograms of all patients undergoing TAVR with Sentinel-CPS between 2016 and 2020 (n = 92) was performed. We investigated the impact of aortic arch anatomy, configuration, and the angles of the supra-aortic arteries, including the determination of vascular tortuosity index on device failure of Sentinel-CPS application.Results: The Sentinel-CPS was applied successfully in 83 patients (90.2%). Device failure in nine patients (9.8%) was due to the infeasibility to perform correct deployment of both filters (n = 7) and to obtain peripheral radial access (n = 2). Patients with a failure of Sentinel-CPS application had a higher right subclavian tortuosity index (217 [92-324] vs. 150 [42-252], p = .046), a higher brachiocephalic tortuosity index (27 [5-51] vs. 10 [0-102], p = 0.033) and a larger angulation of the brachiocephalic artery (59° vs. 39°[7-104], p = .014) compared with patients with successful application. A brachiocephalic angle more than 59°was predictive for device failure. No differences in aortic arch anatomy or common carotid artery tortuosity were detected between the groups.Conclusions: Brachiocephalic tortuosity was found to be associated with failure of Sentinel-CPS application. Filter-based usage should be avoided in TAVR patients with a brachiocephalic angle more than 59°.
Background: The Carpentier-Edwards Perimount Magna Ease prosthesis (PME) represents the latest generation of stented bioprostheses used for surgical aortic valve replacement (SAVR). The aim of our study was to evaluate the long-term clinical outcome and hemodynamic performance of the prosthesis with a focus on the incidence and course of structural valve deterioration (SVD) by serial echocardiographic examinations. Methods: SAVR with the PME was performed in 58 consecutive patients between 2007 and 2008.Transthoracic echocardiography was performed preoperatively, at discharge and annually during a 10-year follow-up at the German Heart Center Munich. Results: Mean age at surgery was 62±14 years. At discharge (n=57), the overall mean pressure gradient (MPG) and effective orifice area (EOA) were 15.8±4.1 mmHg and 1.8±0.4 cm 2 , respectively. Moderate patient-prosthesis mismatch (PPM) was present in 18 patients (32%) and severe PPM in 6 patients (11%) at discharge. Ten years following SAVR (n=33), the overall MPG was 16.6±7.3 mmHg and EOA was 1.3±0.4 cm 2 .Thirty-day and late mortality was 2% (n=1) and 21% (n=12), respectively. Survival at 1, 5, and 10 years was 94.7%±3.3%, 91.1%±4.1%, and 77.3%±5.9%, respectively. Freedom from reoperation at 10 years was 88.8%±4.7%. Ten years after PME implantation the cumulative incidence of any SVD, severe SVD, and bioprosthetic valve failure (BVF) was 25%±6%, 14%±5%, and 16%±5%, respectively.
Conclusions:The PME shows an excellent hemodynamic performance over the course of 10 years with development of clinically relevant SVD as late as 6 years post implant, and a 10-year incidence of severe SVD of 14%.
Down-sized homografts demonstrated a durability similar to that of small-sized homografts. Therefore, down-sizing adult-sized homografts by creating a bicuspid valve to fit into the corresponding RVOT in children with congenital heart defects is an excellent method to overcome the shortage of small-sized homografts.
