Transcatheter Aortic Valve Replacement in High-Risk Surgical Patient with Severe Aortic Insufficiency

Abstract

Background: Transcatheter aortic valve replacement (TAVR) is approved by the FDA for severe aortic stenosis (AS) in patients of all surgical risk categories but has yet to be studied for its utility in aortic insufficiency (AI), despite the need for a safe alternative to surgery for prohibitive surgical risk patients. Case Report: We describe a case of a female patient who presented with acute decompensated congestive heart failure (CHF) with New York Heart Association (NYHA) Class IV symptoms. She was found to have severe AI leading to acute decompensation. Two years prior to this, she had aortic valve endocarditis that had potentially resulted in severe AI. Considering her underling comorbidities including diabetes mellitus, hypertension, morbid obesity and multiple myeloma on active chemotherapy at the time of evaluation, the patient was a high-risk surgical candidate for surgical aortic valve repair (SAVR) in view of elevated risk of mortality, infection, and poor wound healing. After critical and comprehensive assessment, transcatheter aortic valve intervention was considered to be an appropriate choice of treatment. TAVR was successfully performed that resulted in immediate improvement of aortic valve func-tion. On subsequent follow-ups, she demonstrated markedly improved symptoms and reduced status to NYHA Class II HF symptoms. Conclusion: TAVR is a potential treatment modality for patients with severe AI who are poor surgical candidates for SAVR. We hope our case contributes to the growing pool of studies investigating the utility of TAVR procedure in patients with severe AI.
