This case study highlights functional mitral and tricuspid regurgitation caused by atrial fibrillation. Successful valve repair and a Maze procedure were performed, offering insights into managing this complex cardiac condition.
Area of Science:
- Cardiology
- Cardiac Surgery
- Electrophysiology
Background:
- Functional mitral regurgitation (FMR) and functional tricuspid regurgitation (FTR) often stem from cardiac remodeling in ischemic heart disease or dilated cardiomyopathy.
- Atrial remodeling, particularly annular dilatation, can lead to significant FMR and FTR.
- Atrial fibrillation is a recognized, though less common, cause of atrial remodeling leading to valvular dysfunction.
