BACKGROUND For over 50 years, surgical septal myectomy has been the preferred treatment for drug-refractory heart failure symptoms in patients with obstructive hypertrophic cardiomyopathy (HCM). Over this time in the United States, the majority of myectomy operations have been performed in a small number of select referral centers. METHODS We have taken the opportunity to report results from ...

Since the first procedure performed by Sigwart at the Royal Brompton Hospital of London in 1994, alcohol septal ablation (ASA) has become a highly popular technique for the treatment of obstruction in hypertrophic cardiomyopathy (HCM). Percutaneous procedures have revolutionized the treatment of ischemic heart disease and arrhythmias and, more recently, there has been a great upsurge in their u...

Abstract Background Left atrial diameter (LAD) is an established predictor of fibrillation (AF) and adverse outcomes in hypertrophic cardiomyopathy (HCM). However, the impact LAD remodelling after surgical myectomy on development late onset AF still poorly understood. Purpose To investigate association between new occurrence first five years a large patient population with HCM. Methods 1177 HCM...

Survival of patients with severe congenital aortic stenosis beyond third decade is uncommon. This report describes a 31 year old patient who underwent successful aortoplasty and in addition septal myectomy for complete relief of left ventricular outflow obstruction.

A 33-year-old woman who reported syncope and dyspnea on exertion was diagnosed with hypertrophic cardiomy-opathy and scheduled to undergo surgical septal myectomy to relieve a severe obstruction in the left ventricular (LV) outflow tract. On transthoracic echocardiography, asymmetrical septal hypertrophy and systolic anterior motion of the mitral leaflet were noted, and the peak velocity in the...

Hypertrophic obstructive cardiomyopathy (HOCM) is an inherited disorder with variable expressivity, resulting in asymmetric septal hypertrophy and left ventricular outflow tract obstruction (LVOTO). Symptoms are similar to those of aortic stenosis and are due to LV diastolic dysfunction and myocardial ischemia in the absence of epicardial coronary narrowing. Goals of treatment include symptomat...

We have reviewed the surgical management of essential blepharospasm over the last 15 years, comparing the results from facial nerve avulsion with those from orbicularis muscle stripping. After facial nerve avulsion 50% of patients remained free of troublesome spasm for 15 months after surgery, but only 25% remained so for more than two years. Following orbicularis oculi myectomy 50% of patients...

Left atrial (LA) volumes are known to be increased in hypertrophic cardiomyopathy (HCM) and are a predictor of adverse outcome. In addition, LA function is impaired and is presumed to be due to left ventricular (LV) diastolic dysfunction as a result of hypertrophy and myocardial fibrosis. In the current study, we assess the incremental effect of outflow tract obstruction (and concomitant mitral...

OBJECTIVES To present the outcomes of unilateral inferior oblique myectomy performed in patients with inferior oblique overaction due to superior oblique palsy. MATERIALS AND METHODS Twenty-seven eyes of 27 patients that underwent inferior oblique myectomy surgery for superior oblique palsy between 2002 and 2008 were included. Inferior oblique overaction scores (between 0-4) at preoperative, ...
