[Aortic valve replacement with simultaneous aorto-coronary bypass operation 1969-1980]

Area of Science:

• Cardiovascular Surgery
• Cardiac Valve Surgery
• Coronary Artery Bypass Grafting

Context:

• Between 1969 and 1980, 62 patients underwent combined aortic valve replacement and aorto-coronary bypass procedures.
• Patients were stratified into three groups based on predominant aortic valve disease, coronary heart disease, or simultaneous severe conditions.

Purpose:

• To analyze the operative risk and late outcomes of combined aortic valve replacement and aorto-coronary bypass implantation.
• To evaluate the impact of disease severity on patient outcomes in combined procedures.

Summary:

• Patients with severe aortic valve disease undergoing combined surgery showed acceptable operative risk.
• Conversely, patients with predominant coronary disease receiving aortic valve replacement experienced increased operative mortality and perioperative infarctions, likely due to patient selection.
• Late mortality correlated with coronary heart disease severity, and combined procedures offered less favorable long-term prognosis than isolated interventions, with continued risk of angina and myocardial infarction.

Impact:

• Identified patient selection as a critical factor influencing outcomes in combined cardiac surgeries.
• Highlighted the increased late mortality associated with the severity of coronary heart disease in this patient cohort.
• Underscored the need for careful risk assessment and patient selection for combined aortic valve and coronary artery bypass procedures.
