Abstract
Complete atrioventricular (AV) block is a well-known cause of diastolic AV regurgitation. In patients with complete AV block, the effective and synchronized ventricular systole may not occur at the end of diastole, leading to the incomplete closure of AV valve. And the reversal pressure gradient between ventricle and atrium due to the delay in ventricular systole results in diastolic AV regurgitation. We report a case of tricuspid and mitral regurgitation after new-onset complete AV block.
