Abnormal mitral valve apparatus in a case of hypertrophic obstructive cardiomyopathy: Intraoperative transesophageal echocardiography. Annals of Cardiac Anaesthesia. 2018 Jul; 21(3): 315-3180971-9784http://imsear.searo.who.int/handle/123456789/185742Hypertrophic obstructive cardiomyopathy is a relatively common disorder that signifies asymmetric hypertrophy of interventricular septum causing obstruction of the left ventricular outflow tract (LVOT). However, more recent studies have shown that during ventricular systole, flow against an abnormal mitral valve apparatus results in drag forces on the part of the leaflets. The mitral leaflet is pushed into the LVOT to obstruct it. We present a case where intraoperative transesophageal echocardiography played a crucial role in defining the etiology of LVOT obstruction that subsequently helped in deciding the surgical plan.Abnormal mitral valve apparatusAsymmetric septal hypertrophytransesophageal echocardiographyJournal ArticleIndiaDepartment of Cardiothoracic and Vascular Anesthesia, Dr. B.
