Summary
Percutaneous mitral valvuloplasty can cause left bundle branch block, specifically a "biblock." This finding supports the trifascicular concept of the left bundle branch in cardiac conduction.
Area of Science:
- Cardiology
- Electrophysiology
- Cardiac Anatomy
Background:
- Percutaneous mitral valvuloplasty (PMV) is a procedure to treat mitral stenosis.
- Intraventricular conduction abnormalities can occur during PMV due to balloon inflation.
- The left bundle branch of the His bundle is crucial for ventricular depolarization.
