Key words: long-term outcomes, quadricuspid aortic valve, transcatheter aortic valve replacement
Case #1. A 79-year-old man was admitted to the hospital for severe aortic stenosis and moderate aortic regurgitation. A 4-leaflet, which was classified as a type E quadricuspid aortic valve (QAV),1 was found during the analysis of contrast-enhanced computed tomography (CT) images (Figures 1A, 1B, 1D). Transcatheter aortic valve replacement (TAVR) was then successfully performed with a 23 mm Venus A valve (Medtech). No abnormality of prosthesis was found at annual CT examination (Figures 1C, 1E). No major adverse cardiovascular events occurred during 5 years of follow-up until now.
Case #2. A type B QAV was found on CT in an 86-year-old man (Figures 1F, 1G, 1I). The TAVR procedure was successfully performed with a 26 mm Sapien XT valve (Edwards Lifesciences) for severe aortic stenosis and moderate-to-severe aortic regurgitation (Figures 1H, 1J). The patient was also free of major adverse cardiovascular events during 3 years of follow-up.
Our study reported the first 2 cases of long-term outcome after TAVR in QAV. Neither valve structure deterioration nor major adverse cardiovascular events occurred in these 2 patients, suggesting a satisfactory long-term outcome. The first patient is the first reported case of TAVR in a type E QAV patient.
