Influence of mitral valve surgery on tricuspid incompetence concomitant with mitral valve disease.

abstract：BACKGROUND:The cyclin-dependent kinase inhibitor p27(kip1) is a key regulator of smooth muscle cell and leukocyte proliferation in vascular disease, including in-stent restenosis. We therefore hypothesized that common genetic variations or single nucleotide polymorphisms in p27(kip1) may serve as a useful tool in risk ...
