title: Chordal tethering: a unique cause of structural mitral regurgitation in dilated cardiomyopathy.
abstract: Mitral regurgitation in dilated cardiomyopathy is usually considered "functional," and many such patients are treated medically. Surgery is often offered as a last resort in select patients who have failed medical therapy. We report a patient with dilated cardiomyopathy with ventricular tachycardia and ventricular dyssynchrony and "structural mitral regurgitation" due to chordal tethering, which was managed surgically using a minimally invasive approach.
