Insights

Surgical ventricular restoration improves heart function and survival for patients with ischemic heart failure. Key predictors of operative mortality include mitral regurgitation and heart failure severity.

Area of Science:

  • Cardiology
  • Cardiac Surgery
  • Heart Failure Management

Background:

  • Ischemic heart failure often leads to ventricular remodeling and reduced cardiac function.
  • Surgical ventricular restoration (SVR) is a procedure aimed at improving cardiac performance in these patients.

Purpose of the Study:

  • To evaluate operative and long-term mortality after anterior SVR.
  • To assess changes in clinical and cardiac status post-SVR.
  • To identify predictors of death in a large SVR cohort.

Main Methods:

  • 1161 patients underwent anterior SVR (with or without CABG/mitral repair) between 1998-2005.
  • Echocardiography was performed in 488 patients.
  • Indications included heart failure, angina, or both.

Main Results:

  • 30-day mortality was 4.7% overall and 4.9% in the echocardiography group.
  • Mitral regurgitation and need for mitral valve repair/replacement predicted hospital mortality.
  • Ejection fraction improved (33% to 40%), volumes decreased, and NYHA class improved (2.7 to 1.6).
  • Long-term survival was 63% at 120 months.

Conclusions:

  • Anterior SVR effectively reduces ventricular volumes and improves cardiac function and functional status in ischemic heart failure.
  • The procedure has acceptable operative mortality and good long-term survival.
  • Significant mitral regurgitation, advanced NYHA class, and diastolic dysfunction are predictors of operative mortality.
