Summary
Radiofrequency catheter ablation for Wolff-Parkinson-White syndrome can rarely cause severe mitral regurgitation. This case report details a posterior mitral leaflet perforation following ablation, requiring surgical repair.
Area of Science:
- Cardiology
- Electrophysiology
- Cardiac Surgery
Background:
- Radiofrequency catheter ablation is a common procedure for treating accessory pathways.
- Wolff-Parkinson-White syndrome necessitates ablation to prevent arrhythmias.
- Complications, though rare, warrant careful consideration and reporting.
Observation:
- A 15-year-old male with Wolff-Parkinson-White syndrome underwent multiple radiofrequency catheter ablations.
- Following a successful ablation, the patient developed severe mitral regurgitation.
- Echocardiography revealed a posterior mitral leaflet perforation as the cause.
Findings:
- The patient presented with chest pain and dyspnea on exertion.
- Severe mitral regurgitation was diagnosed due to posterior mitral leaflet perforation.
- Surgical intervention was required, involving video-assisted mitral valve repair.
Implications:
- This case highlights a very rare complication of radiofrequency catheter ablation for accessory pathways.
- It underscores the importance of considering even uncommon adverse events post-ablation.
- Mitral valve repair can be successfully performed for iatrogenic leaflet perforation.

01:27Mitral Valve Prolapse I: Introduction
IntroductionThe mitral valve, one of the heart's four valves, regulates blood flow. These valves have flaps that open and close to direct blood properly through the heart and body. During each heartbeat, the flaps open for blood to pass through and seal shut to prevent backflow. Specifically, the mitral valve opens to allow blood flow from the heart's upper left chamber to the lower left chamber. It then closes securely as the lower left chamber contracts to pump blood to the body, preventing...
01:22Mitral Stenosis I: Introduction
Mitral Valve Stenosis (MVS) is a heart condition where the mitral valve narrows, impeding blood circulation from the left atrium to the left ventricle. The etiology and pathophysiology of this condition are multifaceted, leading to a cascade of cardiovascular complications.Causes of Mitral Valve StenosisRheumatic Heart Disease: It is the main cause of mitral valve stenosis, particularly in developing nations. This condition arises from rheumatic fever, an inflammatory illness resulting from...
01:26Mitral Stenosis III: Medical Management
Mitral stenosis, a condition marked by the narrowing of the mitral valve, necessitates an integrated approach for effective management. This approach includes preventative measures, medical therapy, and surgical interventions to reduce symptoms and prevent complications.PreventionPrevention of mitral stenosis primarily focuses on reducing the incidence of bacterial infections, particularly streptococcal infections, which can lead to rheumatic fever and subsequent valvular damage.
