Summary
Beating heart mitral valve replacement was successfully performed in a patient with severe aortic calcification. This complex procedure addressed mitral stenosis in a high-risk patient with a porcelain aorta.
Area of Science:
- Cardiovascular Surgery
- Cardiac Valve Disease
- Thoracic Aortic Disease
Background:
- Mitral valve stenosis necessitates surgical intervention.
- Porcelain aorta presents significant surgical challenges.
- Prior aortic valve replacement increases procedural complexity.
Observation:
- A 77-year-old patient presented with recurrent heart failure.
- Severe calcification of the ascending aorta and aortic arch was noted on CT scan.
- The patient had a history of aortic valve replacement.
Findings:
- Beating heart mitral valve replacement was successfully completed.
- Cardiopulmonary bypass was established using bicaval drainage and aortic return.
- Epiaortic echocardiography guided the procedure.
Implications:
- Beating heart techniques can be feasible in complex aortic calcification cases.
- Successful mitral valve replacement can improve outcomes in high-risk patients.
- This case highlights advanced surgical strategies for complex valve disease.
