Transjugular Tricuspid Valve-in-Valve Replacement [PDF]

Circulation, 2011
The patient is a 38-year-old woman with rheumatic heart disease requiring surgery 21 years ago. She received a St. Jude mechanical prosthesis in the mitral position and a Carpentier-Edwards Perimount bioprosthesis (size 31) in the tricuspid position. Over the past 2 years, she has become progressively more short of breath with regular admissions for ...

Same-Day Discharge After Transcatheter Native Aortic and Mitral Valve-in-Valve Replacement

JACC: Case Reports, 2020
Transcatheter aortic valve replacement has become the gold standard of care in the management of patients with severe aortic stenosis and transcatheter mitral valve-in-valve replacement seems to be an attractive alternative to redo surgery. We report the

Tricuspid Stenosis in Pregnancy

JACC: Case Reports, 2020
Redo tricuspid valve replacement has high surgical operative mortality. Transcatheter valve-in-valve provides a viable option for valve replacement. We discuss the decision-making process involved in performing transcatheter tricuspid valve-in-valve ...

Microphysiological Glomerular Filtration Barriers: Current Insights, Innovations, and Future Applications

Advanced Biology, EarlyView.
The glomerular filtration barrier (GFB) is the first step of blood filtration by the kidneys. The concerning increase of kidney diseases makes the development of new models essential. In this context, microphysiological glomerular filtration barriers focus on closely reproducing the physiological architecture of the in vivo GFB: podocytes, glomerular ...

Transcatheter aortic valve implantation vs. surgical aortic valve replacement for treatment of symptomatic severe aortic stenosis: an updated meta-analysis.

European Heart Journal, 2019
AIMS Owing to new evidence from randomized controlled trials (RCTs) in low-risk patients with severe aortic stenosis, we compared the collective safety and efficacy of transcatheter aortic valve implantation (TAVI) vs.
