Diastolic mitral and tricuspid regurgitation is due to a positive ventricular-to-atrial (V-A) pressure gradient occurring during diastole, and is commonly observed in patients with AV block.1–3 In this case, the V-A gradient develops because the atrial relaxation is not followed by a properly timed ventricular contraction; as a consequence, atrial pressure falls below the subsequently elevated ventricular pressure, which has been increased by the preceding atrial contraction.

Abstract
Diastolic mitral and tricuspid regurgitation is due to a positive ventricular-to-atrial (V-A) pressure gradient occurring during diastole, and is commonly observed in patients with AV block.1–3 In this case, the V-A gradient develops because the atrial relaxation is not followed by a properly timed ventricular contraction; as a consequence, atrial pressure falls below the subsequently elevated ventricular pressure, which has been increased by the preceding atrial contraction.File in questo prodotto:
