Intraoperative Two- and Three-Dimensional Transesophageal Echocardiography in Combined Myectomy-Mitral Operations for Hypertrophic Cardiomyopathy - 02/03/18
Abstract |
Transesophageal echocardiography is essential in guiding the surgical approach for patients with obstructive hypertrophic cardiomyopathy. Septal hypertrophy, elongated mitral valve leaflets, and abnormalities of the subvalvular apparatus are prominent features, all of which may contribute to left ventricular outflow tract obstruction. Surgery aims to alleviate the obstruction via an extended myectomy, often with an intervention on the mitral valve and subvalvular apparatus. The goal of intraoperative echocardiography is to assess the anatomic pathology and pathophysiology in order to achieve a safe intraoperative course and a successful repair. This guide summarizes the systematic evaluation of these patients to determine the best surgical plan.

• | Intraoperative two- and three-dimensional TEE is crucial for HCM patients. |
• | Measure septal thickness, mitral leaflet length, and assess subvalvular apparatus. |
• | The septum is best measured from the three-chamber long-axis and transgastric views. |
• | Use 3D TEE from the LV side, “looking up”, to visualize mitral valve. |
• | Interactive communication with the surgeon before and after bypass is key. |
