Aorto-coronary vein bypass and valvular surgery
Scandinavian Journal of Thoracic and Cardiovascular Surgery
|January 1, 1977
Summary
Combined valvular surgery and aorto-coronary bypass showed a 19% mortality but improved function in most survivors. Early surgery for patients in functional class II and III yields good results, avoiding high-risk class IV patients.
Area of Science:
- Cardiovascular Surgery
- Cardiac Valve Surgery
- Coronary Artery Bypass Grafting
Background:
- Valvular heart disease often coexists with coronary artery disease.
- Surgical intervention aims to improve patient outcomes and quality of life.
Purpose of the Study:
- To evaluate the outcomes of combined valvular surgery and aorto-coronary saphenous vein bypass.
- To assess the early and late mortality and clinical improvement in patients undergoing these combined procedures.
Main Methods:
- A retrospective review of 26 patients who underwent combined valvular surgery and aorto-coronary saphenous vein bypass between 1972-1975.
- Procedures included aortic valve replacement, mitral valve replacement, or double valve replacement using Björk-Shiley valves.
- Saphenous vein grafts were utilized for bypass procedures.
Main Results:
- Overall mortality was 19%, with early deaths in NYHA functional class IV patients.
- Late deaths occurred in 2 patients from functional class III.
- 19 of 21 survivors showed functional improvement (at least one class), with 95% graft patency at follow-up.
Conclusions:
- Combined valvular surgery and aorto-coronary vein bypass demonstrate low mortality and favorable clinical results in functional class II and III patients.
- Optimal outcomes are achieved when surgery is performed before patients reach advanced functional class IV.
- The procedure offers good clinical and hemodynamic benefits for carefully selected patients.
