Transcatheter Aortic Valve Implantation in a Woman with Porcelain Aorta, Previous Sternotomy for Coronary Artery Bypass Grafting, and Critical Aortic Stenosis.
A 74-year-old woman who was diagnosed with right breast cancer at age 39 had been treated with mastectomy, and repeated cycles of chemotherapy and radiotherapy. She also had a history of coronary artery disease, wherein two coronary artery bypass grafts were performed 3 years ago. At that time, porcelain aorta was detected during surgery. In the year prior to admission, the patient presented with severe symptomatic critical aortic stenosis. Due to the prohibitively high surgical risk and need for aortic valve replacement, she underwent successful transcatheter aortic valve implantation with transfemoral implantation of a 29 mm Medtronic CoreValve prosthesis. The patient experienced a good result with reduction of the transaortic gradient and mild residual aortic regurgitation.
