Abstract 16851: Simultaneous Mitral Valve Replacement, Aortic Valve Replacement, Tricuspid Valve Repair, Left Atrial Appendage Ligation, Maze Procedure And Cabg In A 57-year Old Female With History Of Tavr And Severe Mitral Annular Calcification

Background: Open heart surgery is preferred for patients with multiple valvular issues with conflicting physiology. Case: A 57-year-old female with a past medical history of Type I Diabetes Mellitus complicated by kidney & pancreatic transplant in 1999 s/p failed kidney transplant in 2016 subsequently back on dialysis, aortic stenosis leading to Transcatheter Aortic Valve Replacement (TAVR) in 2016 who presented to the hospital for profound cardiogenic shock and was found to have severe tricuspid regurgitation, severe mitral stenosis secondary to mitral annular calcification with severe concentric hypertrophy of left ventricle. Decision Making: Her conflicting right and left heart physiology due to Tricuspid Regurgitation and Mitral Stenosis was very difficult to manage medically. She was not deemed a candidate for a heart transplant due to a history of a failed kidney transplant. She underwent surgery which included Mitral Valve Replacement, explant TAVR and repeat aortic valve replacement, Tricuspid repair, Left atrial appendage ligation and maze procedure, and CABG x1 with saphenous vein graft to PDA. She stayed on V-V extracorporeal membrane oxygenation (ECMO) post-operatively and was discharged on post-operative Day # 14. Conclusion: Severe tricuspid Regurgitation & coexisting mitral stenosis pose a dilemma for medical management and only feasible option is surgery which could be extremely challenging.
