Summary
A complex cardiac surgery involving aortic root and mitral valve replacement was performed via a novel aortic root approach. This technique offers potential benefits in reducing surgical trauma and heart-stopping duration in select patients.
Area of Science:
- Cardiovascular Surgery
- Cardiac Valve Disease
- Aortic Aneurysm
Background:
- Severe aortic regurgitation and mitral valve insufficiency present significant surgical challenges.
- Active endocarditis complicates the management of aortic and mitral valve pathology.
- Ascending aortic aneurysms require complex reconstructive procedures.
Observation:
- A 30-year-old male patient presented with severe aortic regurgitation, ascending aortic aneurysm, and mitral valve insufficiency with active endocarditis.
- A combined aortic root replacement using a composite graft and mechanical mitral valve replacement was performed.
- The mitral valve was accessed through the aortic root after aortic valve cusp excision, a rarely employed technique.
Findings:
- Successful combined aortic root and mitral valve replacement was achieved.
- The trans-aortic root approach for mitral valve replacement was utilized in this complex case.
- This surgical approach facilitated access despite significant aortic root dilation.
Implications:
- Mitral valve replacement through the aortic root is a viable, albeit uncommon, surgical strategy.
- This technique may reduce operative trauma and myocardial ischemic time in carefully selected patients.
- Further research into the application and outcomes of this approach in complex valve disease is warranted.
