简介
Objective
To assess autograft, homograft and ventricular function, as well as exercise capacity, in adult patients who have undergone the Ross procedure.
Setting
Single centre paediatric and adult congenital heart disease unit.
Patients
45 subjects (24.6 years, range 16.9–52.2 years) who underwent the Ross procedure between 1994 and 2006 (8.1 years after the Ross operation, range 2.0–14.0 years).
Interventions
Cardiovascular magnetic resonance imaging, echocardiography and cardiopulmonary exercise testing.
Main outcome measures
Autograft and homograft stenosis, and regurgitation. Autograft size. Biventricular function, scar volume and exercise capacity.
Results
Mean autograft regurgitation was 6.8%±8.3% (trivial regurgitation) and diameter was 40.0±7.0 mm. Mean homograft velocity was 2.4±0.6 m/s (mild-moderate stenosis) and regurgitation was 6.1%±8.3% (trivial regurgitation). Biventricular …
