Overview
Current clinical research projects examine the effects of patient characteristics and surgical technique in outcome after minimally invasive cardiac surgery, valve repair and replacement, and coronary artery bypass grafting.
Prior work has examined the role of surgical therapy versus medical therapy in aortic dissection, load-independent means to quantify left and right ventricular function, and management of complex coronary disease.

Survival After Mechanical vs Biological Mitral Valve Replacement: Influence of Age vs Operative Mortality Score.
Journal article Ann Thorac Surg · July 2026 BACKGROUND: Although predicted risk of operative mortality (PROM) varies among patients, current guidelines favor bioprostheses for patients aged over 65 or 70 years. We compared survival after biological vs mechanical mitral valve replacement (MVR), and a ... Full text Link to item CiteThe Importance of Patient Life Expectancy.
