Comparison of the Results of Cardiopulmonary Exercise Testing between Healthy Peers and Pediatric Patients with Different Echocardiographic Severity of Mitral Valve Prolapse

Abstract: Patients with mitral valve prolapse (MVP) have been reported to have exercise intolerance. However, the underlying pathophysiological mechanisms and their physical fitness remain unclear. We aimed to determine the exercise capacity of patients with MVP through the cardiopulmonary exercise test (CPET). We retrospectively collected the data of 45 patients with a diagnosis of MVP. Their CPET and echocardiogram results were compared with 76 healthy individuals as primary outcomes. No significant differences regard… Show more

“…Recently, our team observed that patients with MVP had similar exercise capacity (as indicated by peak metabolic equivalent [MET] measured during CPET); however, they had significantly lower peak rate pressure product (PRPP) values than healthy peers. The reduced PRPP indicates compromised coronary perfusion and subtle left ventricular function impairment in patients with MVP [23]. To our best knowledge, this is the first study in the literature that uses this method in patients with MVP.…”
