Key result
Young MVP patients have more serious VAs than adults despite a similar ~88% arrhythmia rate.
Why the study?
Are arrhythmias more frequent or serious in young patients with mitral valve prolapse compared to adult patients?
Observational (n=68)
Are arrhythmias more frequent or serious in young patients with mitral valve prolapse compared to adult patients?
Young patients with mitral valve prolapse frequently experience serious ventricular arrhythmias, often without symptoms or cardiac dysfunction, highlighting the need for careful monitoring.
Serious VA may be more frequent in young MVP; hypothesis-generating for age-specific monitoring, should not yet change practice.
Twenty four-hour ambulatory ECG monitoring were examined in 68 patients (33 patients in a young group and 35 patients in an adult group) with mitral valve prolapse (MVP) in order to characterize the features of arrhythmias in young patients with MVP in comparison with those in adult patients. Diagnosis of MVP was made by two-dimensional echocardiography. On 24-hour ambulatory ECG monitoring 29 patients (88%) in a young group had arrhythmias which was as frequent as those in adult group, but serious ventricular arrhythmias were more often detected in the young group (7 patients) than in the adult group (2 patients). It was considered that arrhythmias in young patients with MVP were frequently serious but accompanied without any symptoms and cardiac dysfunction.

Kumaki et al. (1984) conducted an observational in Mitral valve prolapse (n=68). Young age vs. Adult age was evaluated on Arrhythmias on 24-hour ambulatory ECG monitoring. Young patients with mitral valve prolapse experienced arrhythmias at a similar rate to adults (88%), but serious ventricular arrhythmias were more frequent in the young group (7 vs 2 patients).
