Diastolic Regurgitation at Inflow Valve (Mitral and Tricuspid) in Second Degree Atrioventricular Block

Mitral regurgitation during diastole is not uncommon among patients with atrioventricular (AV) block, severe aortic regurgitation, and cardiomyopathies (restrictive, and dilated). It results because of atrial contraction which followed by asynchronized ventricular contraction leading into reversal of atrioventricular pressure gradient during atrial diastole. Here, we report a case of diastolic mitral
