Prevalence, multimodality imaging characterization, and mid-term prognosis of quadricuspid aortic valves: an analysis of eight cases, based on 160 004 exams performed during 12 years in a tertiary care hospital

Abstract: Aims Quadricuspid aortic valve (QAV) is a rare abnormality, which may cause aortic regurgitation (AR) requiring surgical intervention in some patients. The characteristics associated with aortic valve functional degeneration in patients with QAV are still unknown. The aim of this study is to describe QAV prevalence, characterize the disease by multimodality imaging, evaluate predictors of severe AR, and assess mid-term prognosis. Methods and r… Show more

“…Significant QAV dysfunction often occurs in middle-aged patients and results in a surgical treatment. About one-third of the patients with QAV require aortic valve surgery[ 26 ] and patients’ complaints are mostly related to congestive heart failure (CHF) symptoms due to stenosis and/or significant valve insufficiency[ 27 ].…”
