Insights

Surgical anterior ventricular endocardial restoration improved left ventricular (LV) function and reduced volumes long-term. Preserved arterial graft patency is key to maintaining these positive LV remodeling outcomes.

Area of Science:

  • Cardiology
  • Cardiac Surgery
  • Medical Imaging

Background:

  • Surgical anterior ventricular endocardial restoration (SAVER) is a complex procedure aimed at improving left ventricular (LV) function.
  • Total arterial revascularization (TAR) is often performed concurrently to ensure optimal coronary blood supply.

Purpose of the Study:

  • To evaluate the long-term changes in LV function and volumes following SAVER.
  • To assess the impact of SAVER on LV remodeling and patient survival.

Main Methods:

  • A cohort of 63 patients undergoing SAVER and TAR were assessed using echocardiography and myocardial single-photon emission computed tomography (SPECT) up to 5 years post-surgery.
  • Coronary angiography was performed at 5 years to evaluate arterial graft patency.

Main Results:

  • Operative mortality was 7.9%. Echocardiography showed sustained improvement in LV ejection fraction and reduced LV volumes at 5 years.
  • SPECT confirmed gradual LV ejection fraction improvement and stable reduced LV volumes.
  • Arterial graft patency was high (95.7%) in the left coronary territory, with 10-year survival at 59.2%.

Conclusions:

  • SAVER leads to sustained improvements in LV ejection fraction and reduced LV volumes.
  • High arterial graft patency likely contributes to the preserved LV function post-SAVER.
  • The procedure offers significant long-term benefits for LV remodeling and patient survival.
