In case of late posterior failure of mitral valve repair for severe degenerative, re-repair is feasible in about 70% of the patients with encouraging results at 10 years.
Endovascular VR was easily performed in sheep with failed BP in the tricuspid position. The novel delivery catheter allowed adequate repositioning of our fully deployed VS before its definitive release. One may anticipate that the safety improvement conferred by this new technology will certainly favor the development of percutaneous VR in clinical practice.
ith the increasing practice of mitral valve repair (MVR) worldwide, more and more surgeons will face cases of valve repair failure. Systolic anterior motion (SAM) is now an infrequent complication of MVR that may lead to early valve repair failure necessitating revision or valve replacement. However, previous studies have shown that most patients with SAM could be successfully managed with medical treatment. 1 To the best of our knowledge, SAM as a cause of late valve repair failure necessitating reoperation has not been previously described.We report here a case of SAM with left ventricular outflow tract obstruction and mitral regurgitation that did not regress under medical treatment and required a redo valve repair 8 years after the first operation.
Hemin caused in vitro induction of heme oxygenase 1 in human internal thoracic artery and radial artery grafts. This induction resulted in a reduced contractility to norepinephrine, partially through the cyclic guanosine monophosphate-dependent pathway. This effect was independent from nitric oxide synthesis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
