Cardiac valve replacement and coronary bypass grafts

Area of Science:

• Cardiology
• Cardiac Surgery

Background:

• Coronary artery disease and valvular heart disease often coexist.
• Surgical intervention may involve combined procedures for improved outcomes.

Purpose of the Study:

• To evaluate the outcomes of combined cardiac valve replacement and coronary artery bypass grafting.
• To compare the operative mortality of combined procedures with isolated surgeries.

Main Methods:

• Retrospective analysis of 72 patients undergoing combined cardiac valve replacement and coronary artery bypass grafting over six years.
• Data collected on patient demographics, valve types, graft numbers, bypass times, and operative mortality.

Main Results:

• Average patient age was 58 years; 81% had aortic valve replacement, 18% mitral valve replacement.
• Operative mortality was 8% for combined procedures, not significantly different from 6% for isolated valve or coronary surgeries.
• Average cardiopulmonary bypass time was 2 hours, with 60 minutes of myocardial ischemia.

Conclusions:

• Combined cardiac valve replacement and coronary artery bypass grafting is associated with an acceptable operative mortality.
• The safety profile of combined procedures is comparable to that of isolated cardiac surgeries.
