Abstract:
An 88-year-old woman with a prior history of aortic stenosis and history of valvuloplasty presented with worsening symptoms of heart failure and dizziness. She underwent successful transcatheter aortic valve replacement (TAVR) without complications. Follow-up echocardiograms revealed a small fistula connecting aorta to the right ventricle. The patient was initially asymptomatic but 3 months later developed overload of the right ventricle and heart failure and chose to continue medical therapy. She died of progressive heart failure at 9 months from onset of fistula. Aorto-right ventricular fistula is a rare complication of TAVR with only four cases reported in literature thus far.

Heart Valves
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...
