Significant Reduction In Mitral Regurgitation After Transcatheter Aortic Valve Implantation In a Patient With Severe Degenerative Aortic Valve Disease, Moderate to Severe Mitral Regurgitation and Normal Ejection Fraction

The best treatment modalities in severe aortic valve disease are surgery and, in selected patients, transcatheter aortic valve implantation (TAVI). At the present time, transcatheter aortic valve implantation performed in inoperable patients or in patients with high surgical risk not only treats the aortic valve stenosis but also treats the low ejection fraction and mitral regurgitation that result from it. An 83-year-old female patient presented with shortness of breath and class 3 angina. Transthoracic and transesophageal echocardiography revealed severe AS, moderate-to-severe MR, and normal ejection fraction. The patient was considered at high risk for aortic valve replacement (Logistic Euroscore 20, STS score 15). A dramatic decrease in the degree of mitral regurgitation was detected after the successful TAVI.
