Journal ArticleDOI
Calcific extension towards the mitral valve causes non-rheumatic mitral stenosis in degenerative aortic stenosis: real-time 3D transoesophageal echocardiography study
Mai Iwataki,Masaaki Takeuchi,Kyoko Otani,Hiroshi Kuwaki,Hidetoshi Yoshitani,Haruhiko Abe,Roberto M. Lang,Robert A. Levine,Yutaka Otsuji +8 more
TL;DR: Calcific extension to the mitral valve in patients with AS reduced effective MAA and the leaflet opening, resulting in a significant non-rheumatic mitral stenosis in one-fourth of the patients.
Journal ArticleDOI
Myocardial perfusion and wall motion in infarction border zone: assessment by myocardial contrast echocardiography.
Marielle Scherrer-Crosbie,Noah Liel-Cohen,Yutaka Otsuji,J. Luis Guerrero,Suzanne Sullivan,Robert A. Levine,Michael H. Picard +6 more
TL;DR: The hypothesis that tethering of normal myocardial segments explains the abnormal wall motion noted at the borders of MI is supported.
Journal ArticleDOI
Prognostic importance of the transmitral pressure gradient in mitral annular calcification with associated mitral valve dysfunction.
Philippe Bertrand,Timothy W. Churchill,Evin Yucel,Mayooran Namasivayam,Samuel Bernard,Yasufumi Nagata,Wei He,Carl T. Andrews,Michael H. Picard,Arthur E. Weyman,Robert A. Levine,Judy Hung +11 more
TL;DR: In MAC-related mitral valve dysfunction, mean transmitral gradient is associated with increased mortality after adjustment for age, sex, andMAC-related risk factors.
Journal ArticleDOI
Effects of exogenous adenosine 3',5'-monophosphate in man. I. Cardiovascular responses.
TL;DR: The cardiac findings in man support in vitro data that 3',5'‐AMP may represent part of the biochemical basis for the myocardial response to catecholamines.
Journal ArticleDOI
Dermatomyositis complicated by generalized amyloidosis. Report of a case.
TL;DR: The concurrence of two rare diseases, dermatomyositis and generalized amyloidosis, prompted this report and suggests the possibility of a causal relation beween the so-called "collagen diseases" and amyloidsosis.
