Transcatheter valve implantation in a stenosed quadricuspid aortic valve

摘要

A 78-year-old man affected by severe symptomatic aortic stenosis was evaluated for transcatheter aortic valve implantation because he was considered a high-risk surgical candidate due to comorbidities and previous coronary artery bypass surgery (EuroSCORE standard 14, logistic 48.26; Society of Thoracic Surgeons mortality score 10.2% and morbidity and mortality 42.5%). Transthoracic echocardiography revealed severe aortic stenosis (mean transvalvular aortic pressure gradient 60 mm Hg) and moderate regurgitation. Computed tomography revealed a quad-ricuspid aortic valve, and multiplanar reconstructed images showed 4 separate thickened leaflets with moderate valve calcification (Figure 1).
