[Severe mitral regurgitation associated with systolic anterior motion of mitral valve occurring after aortic valve replacement and myectomy for aortic stenosis and hypertrophic obstructive cardiomyopathy].
We treated a patient with severe mitral regurgitation associated with systolic anterior motion of the mitral valve that occurred after aortic valve replacement and a myectomy for aortic stenosis and hypertrophic obstructive cardiomyopathy. A 76-year-old woman with aortic stenosis and hypertrophic obstructive cardiomyopathy underwent aortic valve replacement and a myectomy. Following these procedures, transesophageal echocardiography showed severe mitral regurgitation associated with systolic anterior motion. Neither adequate volume loading nor beta-blocker administration was effective for improvement of the systolic anterior motion, but vasoconstrictor administration was effective. We also performed mitral valve replacement. To the best of our knowledge, this is the first reported case of intraoperative management following aortic valve replacement and myectomy for aortic stenosis complicated with hypertrophic obstructive cardiomyopathy. Transesophageal echocardiography was very useful for intraoperative assessment and developing a strategy for improving severe mitral regurgitation.
The overall rate of CI-AKI was 11.1%. GA was significantly higher in patients with CI-AKI than in those without, and correlated positively with changes of renal function after the procedure. After adjusting for age, sex, left ventricular ejection fraction, multi-vessel disease, type and volume of co...

Pseudoaneurysm of the mitral-aortic intervalvular fibrosa (P-MAIVF) is a rare but potentially fatal complication of infective endocarditis and aortic valve surgery. 149 patients with P-MAIVF, including 7 cases in our hospital and 142 cases from the literatures, were comprehensively a...
