Partial left ventriculectomy.

Area of Science:

• Cardiovascular Surgery
• Heart Failure Management

Background:

• Partial left ventriculectomy (PLV) is a surgical procedure for heart failure.
• The procedure has seen declining use globally but remains relevant in specific centers.
• Patient selection and surgical technique refinement are crucial for outcomes.

Purpose of the Study:

• To evaluate the long-term survival rates of patients undergoing PLV for idiopathic dilated cardiomyopathy.
• To assess the impact of refined surgical techniques and patient selection on outcomes.
• To highlight the role of ventricular restoration procedures in managing end-stage heart failure.

Main Methods:

• Retrospective analysis of 63 patients undergoing PLV for idiopathic dilated cardiomyopathy since 1996.
• Comparison of survival rates between initial PLV cases and those with refined techniques and concomitant mitral annuloplasty.
• Assessment of operative mortality and long-term survival (1, 3, and 5 years).

Main Results:

• Initial series of 63 patients had a 9.5% operative mortality and 5-year survival of 45.9%.
• The most recent 33 patients, with improved selection and mitral annuloplasty, achieved 1-, 3-, and 5-year survival rates of 86.5%, 78.6%, and 59.4%, respectively.
• These results suggest significant improvement with procedural refinement.

Conclusions:

• Partial left ventriculectomy, when combined with appropriate patient selection and mitral annuloplasty, offers improved survival for idiopathic dilated cardiomyopathy.
• Ventricular restoration procedures like PLV are vital options for medically refractory heart failure, especially given limited heart transplant availability.
• Further consideration of PLV as an important therapeutic option for end-stage heart failure is warranted.
