Left ventricular aneurysm repair: early survival.

Area of Science:

• Cardiovascular Surgery
• Cardiac Surgery
• Thoracic Surgery

Background:

• Evaluating early survival in patients undergoing left ventricular (LV) repair and myocardial revascularization.
• Assessing the safety and efficacy of combined surgical procedures for LV conditions.

Purpose of the Study:

• To assess the early survival rates and clinical outcomes of patients who underwent left ventricular (LV) aneurysm repair with concomitant myocardial revascularization.
• To analyze the impact of surgical techniques on patient recovery and cardiac function.

Main Methods:

• Retrospective review of 51 patients undergoing LV repair and myocardial revascularization (1998-2003).
• Analysis of various surgical techniques including McCarthy, Jatene-Dor, and Cooley methods.
• Evaluation of preoperative and postoperative cardiac parameters (ejection fraction, chamber dimensions, wall thickness) and clinical outcomes (NYHA class, CCS angina class).

Main Results:

• Overall early mortality was 3.9% (2 patients), with 98% survival at follow-up.
• Significant improvements observed in NYHA functional class (3.3 to 2.0) and CCS angina class (3.4 to 1.9).
• Left ventricular ejection fraction increased from 36.3% to 44.3%, while LV end-diastolic and end-systolic diameters decreased significantly.

Conclusions:

• Left ventricular (LV) aneurysm repair with concomitant myocardial revascularization is associated with acceptable surgical risk.
• The combined procedure demonstrates good early survival rates and significant clinical improvement in patients.
• Surgical intervention effectively enhances cardiac function and alleviates symptoms in patients with LV aneurysms.
