Changes in the left ventricular outflow tract after transcoronary ablation of septal hypertrophy for hypertrophic obstructive cardiomyopathy as assessed by transoesophageal echocardiography and by measuring myocardial glucose utilization and perfusion
Aims and Methods Transcoronary ablation of septal hypertrophy (TASH) leads to marked clinical and haemodynamic improvement in patients with hypertrophic obstructive cardiomyopathy. In order to obtain more detailed information about changes in the outflow tract after TASH, transoesophageal echocardiography and a repeat invasive investigation were conducted before as well as 2 weeks and 6 months ...
متن کاملAcute and long-term results after transcoronary ablation of septal hypertrophy (TASH). Catheter interventional treatment for hypertrophic obstructive cardiomyopathy.
AIMS To evaluate acute and long-term symptomatic, haemodynamic (at rest and during exercise) and electrophysiological results of transcoronary ablation of septal hypertrophy (TASH), a catheter interventional treatment for hypertrophic obstructive cardiomyopathy. METHODS AND RESULTS Sixty-two transcoronary ablations of septal hypertrophy were performed by injection of 4.6+/-2.6 ml 96% ethanol ...
متن کاملSuccessful alcohol septal ablation for late recurrence of left ventricular outflow tract obstruction after surgical myectomy in hypertrophic obstructive cardiomyopathy.
An 18-year-old male patient, known with familial hypertrophic obstructive cardiomyopathy underwent a septal myectomy 10 years ago for significant left ventricular outflow tract (LVOT) obstruction. During follow-up a progressive increase in LVOT gradient was noted in association with severe mitral valve regurgitation. The patient underwent percutaneous alcohol septal ablation to induce regressio...
متن کاملLeft ventricular outflow tract planimetry by cardiovascular magnetic resonance differentiates obstructive from non-obstructive hypertrophic cardiomyopathy.
The relation to the pressure gradient as assessed by echocardiography and the CMR-derived planimetry of the LVOT is not known, no values for the differentiation of obstruction exist. We studied 37 patients with hypertrophic cardiomyopathy and 14 healthy controls using standard sequences with 3D coverage of the left ventricular outflow tract. A cutoff value of 2.7 cm2 identified obstruction as d...
متن کاملElectrocardiographic changes after alcohol septal ablation in hypertrophic obstructive cardiomyopathy.
OBJECTIVE To report acute and mid-term electrocardiographic changes in patients with hypertrophic obstructive cardiomyopathy (HOCM) after alcohol ablation of the first large septal branch of the left anterior descending coronary artery; and to relate electrocardiographic data with the left ventricular outflow tract pressure gradients. PATIENTS Nine consecutive symptomatic patients with HOCM (...
