Fungal endocarditis after transcatheter aortic valve implantation complicated with pseudoaneurysm of the ascending aorta

Fungal endocarditis following transcatheter aortic valve implantation (TAVI) is a rare and serious complication of this procedure. We describe a case of a 75-year-old patient who developed fungal endocarditis …  Read More

Short-Term Results With Ozaki Valved Conduit-A Simple Solution for Patients Needing Right Ventricle to Pulmonary Artery Conduit in a Low-Resource Setting

World J Pediatr Congenit Heart Surg. 2024 Nov;15(6):815-822. doi: 10.1177/21501351241259372. Epub 2024 Sep 10.

ABSTRACT

BACKGROUND: The repair of certain types of complex congenital cardiac defects may require a right ventricle-pulmonary artery (RV-PA) conduit. Using the Ozaki Aortic valve neocuspidization (AVNeo)technique, a valved RV-PA conduit was constructed with an Ozaki valve inside a Dacron graft. This study aims to evaluate the short-term outcome of the Ozaki valved RV-PA conduit.

MATERIAL/METHOD: A total of 22 patients received the Ozaki valved RV-PA conduit from November 2019 until December 2023. The median age was 12 years (interquartile range [IQR], 5.5-21), median body weight was 35 kg (IQR, 15.8-48.5). The conduit was used in 16 patients (72.7%) under 18 years of age. Indications for conduit placement included: anatomic repair of corrected transposition of the great arteries, ventricular septal defect/pulmonary stenosis, conduit replacement, pulmonary atresia with associated anomalies, pulmonary artery aneurysm with dysplastic pulmonary valve, tetralogy of Fallot with coronary artery crossing the right ventricular outflow tract, bioprosthetic pulmonary valve regurgitation, and rheumatic heart disease. Native pericardium was used for the Ozaki valve in 12 patients and bovine pericardium for 10 patients. Conduit sizes ranged from 18 mm to 30 mm.

RESULT: The median intensive care unit stay was 4 (IQR, 2-6) days and the median hospital stay was 9 (IQR, 5.5-13.5) days. There were two perioperative mortalities (9.1%) both unrelated to the conduit. The median follow-up was 12.3 (IQR, 4.43-21.2) months. There was no infective endocarditis of the conduit. The median peak gradient across the conduit was 22 mm Hg (range 0-44 mm), and all were competent with trivial regurgitation on follow up.

CONCLUSION: Creation of an Ozaki valved conduit is an attractive option due to low cost, reproducibility, and excellent hemodynamics. Longer-term studies are needed to confirm the durability.
