“…[ 23 ] A cross-sectional study that examined 100 MVP patients and 100 healthy subjects detected early repolarisation phenomena (a notch in the descending arm of the QRS complex and ST elevation) in 74% of the patients (51% in inferior leads, 23% in I, aVL, and 8% in all three leads) while these phenomena were only observed in six subjects in the control group.

“…Due to the nature of the disease, most of the data regarding the incidence, diagnosis and possible treatment options come from inadequately powered studies either due to confounding factors or low sample number. [7][8][9][22][23][24][25]27,32,[43][44][45][46][47][48][49][50] The scarcity of large-scale, randomised, double-blind studies on the subject should also be noted. Further studies will help clear doubts by adding solid data to the current knowledge on MVP.…”

Mitral valve prolapse (MVP) is a common condition present in 1–3% of the population. There has been evidence that a subset of MVP patients is at higher risk of sudden cardiac death. The arrhythmogenic mechanism is related to fibrotic changes in the papillary muscles caused by the prolapsing valve. ECG features include ST-segment depression, T wave inversion or biphasic T waves in inferior leads, and premature ventricular contractions arising from the papillary muscles and the fascicular system. Echocardiography can identify MVP and mitral annular disjunction, a feature that has significant negative prognostic value in MVP. Cardiac MRI is indicated for identifying fibrosis. Patients with high-risk features should be referred for further evaluation. Catheter ablation and mitral valve repair might reduce the risk of malignant arrhythmia. MVP patients with high-risk features and clinically documented ventricular arrhythmia may also be considered for an ICD.
