Pulmonary position cryopreserved homograft in non-Ross patients: how to improve the results?
OBJECTIVES The outcomes of homografts (HGs) in the reconstruction of the right ventricular outflow tract (RVOT) in non-Ross patients are often considered disappointing, compared with Ross patients; and the risk factors for HG degeneration are still controversial. The objective of this study was to determine the durability and prognostic factors related to the HGs implanted in non-Ross patients ...
متن کاملFactors affecting longevity of homograft valves used in right ventricular outflow tract reconstruction for congenital heart disease.
BACKGROUND Few studies have explored the long-term function of cryopreserved homograft valves used for reconstruction of the right ventricular tract (RVOT) in patients with congenital heart disease. METHODS AND RESULTS Among 205 patients receiving cryopreserved homografts for reconstruction of the RVOT between November 1985 and April 1999, the outcome of 220 homografts in 183 operative surviv...
متن کاملHemodynamic performance of cryopreserved aortic homograft valves during midterm follow-up.
OBJECTIVES The aim of this prospective study of adult patients operated with a cryopreserved aortic homograft was to use serial echocardiographic data to evaluate the postoperative hemodynamic performance of these valves. BACKGROUND Only limited data on hemodynamic performance of aortic homografts at rest and during exercise are available. Controversy also exists regarding incidence and progr...
متن کاملMidterm Follow-up after Cryopreserved Homograft Replacement in the Aortic Position
BACKGROUND The long-term results of homografts used in systemic circulation are controversial. We assessed the long-term results of using a cryopreserved homograft for an aortic root or aorta and its branch replacement. MATERIALS AND METHODS From June 1995 to January 2010, 23 patients (male:female=15:8, 45.4±15.6 years) underwent a homograft replacement in the aortic position. The surgical te...
متن کاملAnnuloplasty of cryopreserved pulmonary homograft with Delrin stent in pulmonary atresia with ventricular septal defect.
A six-year-old child was suffering from pulmonary atresia with ventricular septal defect after a total correction at 1 year of age using a bovine pericardial monocusp valve in the reconstruction of the right ventricle outflow tract. The infant evolved with significant pulmonary valve regurgitation (PVR) and right ventricle dysfunction. On reoperation, a cryopreserved pulmonary homograft (CPH) w...
