Laparoscopic surgery, particularly for abdominal aortic repair, can impair heart function by increasing afterload. This study shows reduced left and right ventricular function due to elevated intra-abdominal pressure during the procedure.

Area of Science:

  • Cardiology
  • Surgical Innovation
  • Anesthesiology

Background:

  • The impact of laparoscopic surgery on cardiac function remains debated.
  • Increased afterload may lead to cardiac dysfunction in patients undergoing abdominal aortic repair.

Purpose of the Study:

  • To investigate the effects of laparoscopic abdominal aortic repair on left ventricular (LV) and right ventricular (RV) function.
  • To assess cardiac response to varying intra-abdominal pressures and patient positions.

Main Methods:

  • Transesophageal echocardiography was used in 15 patients during laparoscopic aortic surgery.
  • Cardiac function was measured in supine and right lateral positions at different intra-abdominal pressures (0, 7, 14 mm Hg).
  • Evaluated parameters included LV/RV function, ejection fraction, stroke volume, and wall stress.

Main Results:

  • Pneumoperitoneum increased arterial blood pressure by 25% and LV systolic wall stress by 38%.
  • LV ejection fraction decreased by 25%, and LV stroke volume decreased by 18%.
  • RV stroke volume changes increased with intra-abdominal pressure, indicating elevated RV afterload.

Conclusions:

  • Carbon dioxide insufflation during laparoscopic aortic surgery can impair both LV and RV systolic function.
  • Increased afterload is the primary mechanism responsible for the observed cardiac dysfunction.
  • Optimal volume status was maintained throughout the procedure.
