Percutaneous transcatheter aortic valve closure successfully treats left ventricular assist device-associated aortic insufficiency and improves cardiac hemodynamics.

Percutaneous transcatheter closure of the native aortic valve to treat de novo aortic insufficiency after implantation of a left ventricular assist device.

Transesophageal echocardiographic guidance of transcatheter closure of the aortic valve in a patient with left ventricular assist device-related severe aortic regurgitation

A 68 year-old man with a severe ischemic cardiomyopathy underwent left ventricular assist device (LVAD) implantation (Heart Mate II device) for destination therapy. He presented 49 months following LVAD implant with worsening heart failure symptoms and new severe aortic regurgitation. Given high risk for both surgical and transcatheter aortic valve replacement, he was admitted for transcatheter...

Aorto-Right Ventricular Fistula Post-Transcatheter Aortic Valve Replacement: Multimodality Imaging of Successful Percutaneous Closure

Transcatheter aortic valve replacement (TAVR) has transformed aortic stenosis therapy, with greater than 200,000 procedures performed worldwide since the first case was performed by the French interventional cardiologist Alain Cribier in 2002. One rare but dreaded complication is aortic periannular rupture, seen in less than 1% of all TAVR procedures. Although TAVR is a safe procedure, with an ...

Successful percutaneous trans-catheter treatment of left ventricular assist device outflow graft stenosis with a covered stent

Left ventricular assist devices improve survival in patients with advanced heart failure but can be associated with significant complication including infection, pump thrombosis, and de novo severe aortic insufficiency. Outflow graft stenosis is a much more rare complication, but one with significant hemodynamic consequences. Surgical repair is often necessary, but many patients are too high ri...

Platypnea-Orthodeoxia Syndrome after Transcatheter Aortic Valve Implantation

Progressive dyspnea and hypoxaemia in the subacute phase after transcatheter aortic valve implantation (TAVI) are uncommon and warrant immediate assessment of valve and prosthesis leaflet function to exclude thrombosis, as well as investigation for other causes related to the procedure, such as left ventricular dysfunction, pulmonary embolism, and respiratory sepsis. In this case, we report the...
