Randomized trial finds elevated diastolic mitral regurgitation rates in patients with atrioventricular conduction abnormalities, suggesting potential diagnostic importance.
Panidis et al. (1986) conducted an observational in Atrioventricular conduction abnormalities (n=40). Atrioventricular block vs. Normal PR interval was evaluated on Late diastolic mitral regurgitation. Late diastolic mitral regurgitation was detected by Doppler imaging in 56% of patients with first degree AV block, compared to 0% of subjects with a normal PR interval.
