Abstract This case report highlights a unique instance of a patient with mitral valve prolapse (MVP) and severe mitral regurgitation (MR) who experienced complete premature ventricular contractions (PVC) suppression immediately after undergoing minimally invasive mitral valve repair. Research into MVP phenomena is enhanced by this exceptional observation because it suggests that mechanical damage from redundant leaflets plays an important role in arrhythmias despite conventional beliefs attributing these events to fibrosis and autonomic dysfunction. This is a middle-aged man with persistent palpitation for 5 months. The electrocardiogram (ECG) findings of PVCs were confirmed through a Holter showing a burden of 32%. The echocardiographic results showed a thickened vegetative mitral valve chordal rupture as a cause of severe MR. A severe MR diagnosis emerged from MVP as the primary condition. The patient received minimally invasive mitral valve repair. Using ECG and Holter monitoring confirmed that PVCs disappeared completely immediately after surgery. Surgical correction of MVP demonstrates its effectiveness in suppressing arrhythmias when pharmacological treatments have failed to provide relief to patients. The mechanical defects of MVP influence arrhythmia development so strongly that treatment strategies for afflicted patients need reevaluation.
