Infolding of the Venus P-Valve After Transcatheter Pulmonary Valve Implantation

“…More than 100 Venus P valves have been implanted worldwide. 7 The initial experience with this valve is promising with excellent patient outcomes. 8 The reported complications after Venus P valve placement were mainly stent migration and stent fractures.…”

Pulmonary valve endocarditis after transcatheter pulmonary valve implantation has been an emerging concern due to the increasing prevalence of transcatheter placement of pulmonary valve in the treatment of residual right ventricular outflow tract stenosis or regurgitation. Pulmonary valve endocarditis is a dreadful complication of transcatheter pulmonary valve implantation that have been reported with Melody valve (Medtronic, Inc., Minneapolis, MN) and Edward Sapien valve (Edwards Life Sciences, Irvine, CA) till date. There are scanty available literatures for pulmonary valve endocarditis with Venus P valve (Venus Medtech, Hangzhou, China) implantation. Furthermore, cardiovascular comorbidity is common in COVID-19 infection with limited evidence of COVID-19 infection concomitant with infective endocarditis. This case happens to be the first reported case of infective endocarditis of pulmonary valve with concomitant COVID-19 infection and also delayed presentation of pulmonary valve endocarditis with Venus P valve implantation.

“…Patients at risk for infolding have marked eccentricity or eccentric calcification of the annulus, especially with valve oversizing, mostly in large valves (29 mm or 34 mm), and resheathing has been attempted. Infolding has been reported with other self‐expanding nitinol valves, such as the Venus P‐Valve for transcatheter pulmonary valve implantation and with self‐expanding nitinol endovascular stent grafts for abdominal aorta and thoracic aorta aneurysms.…”

Transcatheter aortic valve replacement has become a mainstay alternative to surgical aortic valve replacement in patients with severe aortic stenosis at high and intermediate surgical risk. Two commercially approved valves are available in the United States: balloon‐expandable and self‐expanding. We report here a rare complication of a self‐expanding Evolut PRO (Medtronic, Minneapolis, Minnesota) valve failing to expand due to nitinol frame infolding. This results in a malopposed valve with a severe paravalvular leak, even though treated successfully with balloon valvuloplasty. It is important to recognize the characteristic angiographic signature of this complication—the “straight line” sign—and how to avoid this potentially serious complication by balloon valvuloplasty or by recapture and deployment of a new valve.
