Rare complication of bioprosthetic aortic valve replacement.

CE-Perimount aortic bioprosthesis in a 59-year-old-man, implanted 8 years ago, showed non-infective severe structural deterioration. Preoperative echocardiogram demonstrated a prolapsing cusp (Fig. 1(A—C)); however, intra-operative echocardiogram and findings revealed a ‘missing’ leaflet (Figs. 1(D), 2(A and B) and Video 1). www.elsevier.com/locate/ejcts European Journal of Cardio-thoracic Surg...

Transcatheter aortic valve implantation in failed bioprosthetic surgical valves.

IMPORTANCE Owing to a considerable shift toward bioprosthesis implantation rather than mechanical valves, it is expected that patients will increasingly present with degenerated bioprostheses in the next few years. Transcatheter aortic valve-in-valve implantation is a less invasive approach for patients with structural valve deterioration; however, a comprehensive evaluation of survival after t...

Is a stentless aortic valve superior to conventional bioprosthetic valves for aortic valve replacement?

A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was whether a stentless valve is superior to conventional stented valves when tissue aortic valve replacement is performed. Altogether more than 515 papers were found using the reported search, of which 16 represented the best evidence to answer the clinical question. The authors, jou...

Nontuberculous Mycobacteria: An Underestimated Cause of Bioprosthetic Valve Infective Endocarditis

Background.  Atypical mycobacteria, or nontuberculous mycobacteria (NTM), have been barely reported as infective endocarditis (IE) agents. Methods.  From January 2010 to December 2013, cardiac valve samples sent to our laboratory as cases of blood culture-negative suspected IE were analyzed by 16S rDNA polymerase chain reaction (PCR). When positive for NTM, hsp PCR allowed species identificatio...

Valve-in-valve implantation of Medtronic CoreValve prosthesis in patients with failing bioprosthetic aortic valves.

BACKGROUND Transcatheter aortic valve implantation (TAVI) using the Medtronic CoreValve (MCV) system might represent an alternative to conventional redo surgery in older high-risk patients with a failing aortic valve bioprosthesis. METHODS AND RESULTS Symptomatic patients with failing aortic valve bioprosthesis, aged ≥65 years with a logistic EuroSCORE ≥10 % were considered for treatment. Loc...
