Title: | Robotic septal myectomy for hypertrophy cardiomyopathy | Authors: | Cheng, Bor-Chih NAI-HSIN CHI |
Issue Date: | Nov-2022 | Journal Volume: | 11 | Journal Issue: | 6 | Source: | Annals of cardiothoracic surgery | Abstract: | A 65-year-old man presented with symptomatic hypertrophic cardiomyopathy (HCM). The resting pressure gradient over the left ventricular outflow tract was 68 mmHg. There was preserved left ventricular function with an ejection fraction of 68%, with thickened septal muscle and severe mitral regurgitation due to systolic anterior motion (SAM). He underwent alcohol injection into the septal branch of the left anterior descending artery twice with an unsatisfactory result, as the septal branch artery was small. A high pressure gradient over the left ventricular outflow tract and severe mitral regurgitation remained. The patient was scheduled for a robotic myectomy and mitral repair. After surgery, the gradient decreased to 6 mmHg and there was no mitral regurgitation. He was discharged 7 days post-surgery. |
