Summary
Partial left ventriculectomy (PLV) improves ventricular function in end-stage dilated cardiomyopathy. Despite high mortality, PLV offers a valid treatment option for advanced heart failure.
Area of Science:
- Cardiology
- Cardiac Surgery
Background:
- Dilated cardiomyopathy (DCM) is a severe heart condition.
- End-stage DCM significantly impairs ventricular function.
- Partial left ventriculectomy (PLV) is a novel surgical approach.
Purpose of the Study:
- To evaluate the efficacy and outcomes of PLV in patients with end-stage DCM.
- To assess changes in ventricular function and survival rates post-PLV.
Main Methods:
- PLV was performed on 14 patients with end-stage DCM (idiopathic or ischemic).
- Preoperative and postoperative echocardiography assessed ventricular dimensions and function.
- Mitral valve replacement was performed in 11 patients.
Main Results:
- Postoperative echocardiography showed reduced left end-diastolic diameter and improved cardiac index.
- 30-day mortality was 28.6%, with 20-month survival at 57.2%.
- One patient experienced postoperative mitral incompetence.
Conclusions:
- PLV can improve ventricular function in end-stage DCM.
- High mortality necessitates identification of prognostic factors for early failure.
- PLV remains a viable option for select patients with advanced DCM.
