BACKGROUND Concomitant mitral regurgitation (MR) is frequently seen in patients undergoing aortic valve replacement (AVR) for aortic stenosis. This study was undertaken to characterize the magnitude of MR in these patients and identify factors associated with significant postoperative change. METHODS Between 2002 and 2006, 391 patients with stenotic AV disease but no structural mitral valve d...
Valvular disease is common in patients with Marfan syndrome and can lead to cardiomyopathy. However, some patients develop cardiomyopathy in the absence of hemodynamically significant valve dysfunction, suggesting alternative mechanisms of disease progression. Disruption of LDL receptor-related protein-1 (Lrp1) in smooth muscle cells has been shown to cause vascular pathologies similar to Marfa...
A 76-year-old man with severe degenerative aortic stenosis, coronary artery disease, and progressive congestive heart failure with severe systolic dysfunction underwent implantation of a Heartmate II left ventricular assist device (LVAD; Thoratec Corporation, Pleasanton, CA) after developing refractory cardiogenic shock. Because there was moderate aortic insufficiency (AI), the aortic valve was...
AORTIC INSUFFICIENCY that results from an abnormal eommunication that begiiis in the aseending aorta above the level of the coronary arteries, bypasses the aortic valve, and terminates in the left ventricle is rare. Although clinical findings are similar, this condition may be distinguished anatomically from ruptured aortic sinus aneurysm because the abnormal communication which is to be presen...
