2023, Journal of Thoracic and Cardiovascular SurgeryCitation Excerpt :The present study extends the understanding of MV pathology in patients with obstructive HCM, especially with regard to extended septal myectomy for relief of LVOT obstruction. Our findings support previous pathologic, echocardiographic, and cardiovascular magnetic resonance imaging studies that document increased leaflet length in patients with HCM compared with controls.2,10-15 Increased leaflet length, however, did not impact surgical outcome as measured by LVOT gradient relief and residual MV regurgitation.
