A Leak before the Beat: Diastolic Atrioventricular Regurgitation in Conduction Disease

Year: 2026

Type: article

Abstract: Atrioventricular valve regurgitation is typically regarded as a systolic phenomenon. However, mitral regurgitation (MR) and tricuspid regurgitation (TR) may also occur during diastole when ventricular pressure transiently exceeds atrial pressure while the mitral valve (MV) and tricuspid valve (TV) leaflets remain incompletely closed. This entity—diastolic atrioventricular regurgitation—has been described most commonly involving the MV but may also affect the TV in the setting of atrioventricular conduction abnormalities.
