Why the study?
How does the motion of the mitral apparatus contribute to left ventricular outflow obstruction in hypertrophic cardiomyopathy?
How does the motion of the mitral apparatus contribute to left ventricular outflow obstruction in hypertrophic cardiomyopathy?
Echocardiographic analysis suggests that LV outflow obstruction in hypertrophic cardiomyopathy results from systolic contact between the mitral anterior cusp and the posterior papillary muscle, challenging previous theories of septal contact.

May question septal myectomy focus in HCM; challenges consensus but leaves open prospective validation.
