Why the study?
Does valve-in-valve TAVR improve symptoms and decrease fistula flow in a patient with an aorto-right ventricular fistula complicating a prior TAVR?

Valve-in-valve TAVR can be an effective treatment for an aorto-right ventricular fistula complicating a prior TAVR.
May support valve-in-valve for rare post-TAVR fistula; hypothesis-generating and leaves open need for larger studies.
A 59-year-old man with a history of severe aortic stenosis with transcatheter aortic valve replacement (TAVR) presented with worsening heart failure. Echocardiography showed a fistula between the aorta and the right ventricle with mild to moderate paravalvular regurgitation. He underwent a valve-in-valve TAVR with symptomatic improvement and decreased flow through the fistula.
