Retrograde coronary sinus perfusion (RCSP) effectively prevents perioperative infarction in redo cardiac surgery by minimizing atheromatous embolization. This technique preserved ventricular function and ensured survival in all patients, with no associated complications.

Area of Science:

  • Cardiovascular Surgery
  • Cardiac Anesthesia
  • Vascular Embolism

Background:

  • Redo cardiac operations for coronary artery disease are frequent.
  • Perioperative infarction is a significant complication, often caused by atheromatous embolization from grafts.
  • Embolization can lead to distal coronary artery occlusion and myocardial damage.

Purpose of the Study:

  • To evaluate the efficacy of retrograde coronary sinus perfusion (RCSP) for cardioplegia delivery in redo cardiac surgery.
  • To assess the preventive role of RCSP against atheromatous embolization.
  • To determine the safety and impact of RCSP on ventricular function and patient survival.

Main Methods:

  • RCSP was employed for cardioplegia delivery in 3,100 cardiac operations over three years.

  • The study included 65 patients undergoing redo procedures, including aortic valve replacement.
  • Coronary flow was predominantly through patent vein grafts in these patients.

    • Main Results:

    • Ventricular function was well preserved in all 65 patients who received RCSP.
    • All patients undergoing RCSP survived the operation.
    • No complications were directly associated with the use of RCSP for cardioplegia delivery.

    Conclusions:

    • RCSP is an effective method for delivering cardioplegia in redo cardiac operations.
    • Retrograde flow via RCSP successfully prevents atheromatous embolization and perioperative infarction.
    • RCSP is a safe and beneficial technique for preserving cardiac function and improving outcomes in complex cardiac surgeries.
