Objectives. The aim of the present study was to quantitate aortic regurgitant volume and
regurgitant fraction in a chronic animal model with surgically created aortic regurgitation …

Two papers in this issue demonstrate clinical consequences from the presence of clinically
silent mitral regurgitation in paediatric and adolescent populations. Both are potentially …

A method is described whereby mitral valve function can be tested during cardiopulmonary
bypass under physiological conditions. This method avoids the risk of systemic air embolism …

RECENT ADVANCES in ultrasound instrumentation have yielded noninvasive techniques
