When assessing the function of the mitral valve at operation by palpation or inspection, the surest way to prevent systemic (cerebral) embolism is to have the ascending aorta occluded by a clamp. A technique is described which allows safe assessment of mitral valve function by aortic root and left ventricular perfusion, giving a beating-heart preparation with the aorta cross-clamped. This metho...

Fifty-three specimens in which the primary diagnosis in life was coaretation of the aorta were examined; only nine had a mitral valve of normal size and configuration. Ten specimens had a normally formed valve mechanism which was small in comparison to both tricuspid valve and left ventricle. Three other specimens had a normally formed but small valve which exhibited a short free margin of the ...

The therapeutic implications of bicuspid aortic valve associations have come under scrutiny in the transcatheter aortic valve implantation era. We evaluate the spectrum of mitral valve disease in patients with bicuspid aortic valves to determine the need for closer echocardiographic scrutiny/follow-up of the mitral valve. A retrospective analysis of echocardiograms done at a referral hospital o...

BACKGROUND Increased sympathetic activity, commonly reported in mitral valve prolapse, indicates that the sympathetic nervous system might play an important role in regulating mitral interstitial cells. Hence, the aim of this study is to determine the level and pattern of adrenergic receptors expressed in human mitral valve leaflets and to investigate the effect of norepinephrine on physiologic...

The strategy for an infant with congenital mitral stenosis should be determined by three important factors: left ventricular volume, the degree of the systemic outflow tract obstruction, and the type of mitral valve dysfunction. A successful staged biventricular repair in early infancy for a patient who had congenital mitral stenosis with short chordae, hypoplastic left ventricle and coarctatio...

prolapsed mitral valve syndrome is a common, benign disorder with prevalence of %0.3-6 in population. this syndrome also is known as barlows syndrome and flaapy mitral valve syndrome. prolapsed mitral valve is the dropping of one or two mitral valve leaflet(s) into the left atrium during ventricular systole. this malformation leads to incomplete closing of mitral valve and regurgitates the bloo...

repair of the mitral valve is the treatment of choice for mitral valve regurgitation when the anatomy is favorable. it is well known that mitral valve repair enjoys better clinical and functional results than any other type of valve substitute. this fact is beyond doubt regardless of the etiology of the valve lesion and is of particular importance in degenerative diseases. this review analyzes ...
