Current practice of coronary artery bypass surgery. Results of a national survey
Insights
A survey of 400 cardiac surgeons reveals varied techniques in coronary artery bypass graft (CABG) surgery. While extracorporeal circulation is standard, myocardial preservation and graft choices show significant practice diversity.
Area of Science:
- Cardiovascular Surgery
- Surgical Techniques
- Medical Practice Surveys
Background:
- Coronary artery bypass graft (CABG) surgery is a critical intervention for ischemic heart disease.
- Standardization of surgical techniques is essential for patient outcomes.
- Understanding current practices among experienced surgeons provides valuable insights.
Purpose of the Study:
- To survey and analyze the diverse techniques employed by experienced cardiac surgeons in CABG procedures.
- To identify variations in cardiopulmonary bypass, myocardial preservation, and graft selection.
- To document prevalent grafting and suture techniques in 1975.
Main Methods:
- A seventy-question survey was distributed to 400 experienced cardiac surgeons.
- Surgeons reported on techniques used in 41,000 CABG operations performed in 1975.
- Data collected covered cardiopulmonary bypass, myocardial preservation, bypass conduit choice, and grafting methods.
Main Results:
- Extracorporeal circulation was utilized in nearly all surveyed CABG surgeries.
- Significant divergence in practices was observed regarding left ventricular vents and myocardial protection strategies.
- A variety of graft suture techniques were in use, with running double-ended sutures being most common.
- Only 6% of surgeons preferred the internal mammary artery (IMA) over saphenous vein grafts.
Conclusions:
- Despite the widespread use of extracorporeal circulation in CABG, substantial variability exists in myocardial preservation and surgical techniques.
- The choice of bypass conduit showed a strong preference for saphenous vein over the internal mammary artery among the surveyed surgeons.
- These findings highlight the evolving nature and diversity of CABG surgical practices.
Abstract:
A survey of techniques used in coronary artery bypass graft (CABG) surgery by 400 experienced cardiac surgeons is presented. These surgeons performed 41,000 CABG operations in 1975. A seventy-question survey form was answered by each surgeon on their techniques for cardiopulmonary bypass and myocardial preservation, choice of bypass conduit, and grafting techniques. We found that extracorporeal circulation is almost always used in CABG surgery. A wide divergence of practice exists in the use of left ventricular vents and in methods of myocardial protection during coronary artery grafting. A spectrum of graft suture techniques is employed, the most common being a running double-ended suture anastomosis with the end of the vein initially fixed only at its heel to the coronary artery. Only 23 surgeons (6 per cent) prefer the internal mammary artery (IMA) rather than saphenous vein, when feasible, as the bypass conduit of choice for CABG surgery.
