There are many causes of left atrial and left ventricular dilation, and the treatment of this type of mitral regurgitation is directed at the primary cause. For example, if a patient develops ...

Dilated cardiomyopathy (DCM) causes the heart to become enlarged, particularly the left ventricle, and to function (squeeze and pump) poorly. As a result, the heart muscle becomes weak and thin and is ...

With acute mitral regurgitation, the left ventricle cannot adequately compensate and the left atrium is relatively non-compliant and non-dilated; symptoms, usually severe, always occur.

Illustrative cases demonstrating how change in heart rate can affect transient ischemic dilation (TID) ratios. (a) Low-risk left ventricular perfusion pattern (equivocal in the posterobasal ...

Researchers analyzed echocardiographic reports of 792 adult patients with moderate or severe AFMR, dilated left atrium, and ...
