Background: This study aimed to evaluate the efficacy of a novel virtual myectomy procedure in guiding thoracoscopic trans-mitral myectomy. Methods and Results: Clinical data from 37 patients who underwent thoracoscopic trans-mitral septal myectomy ...

Septal ablation in hypertrophic obstructive cardiomyopathy improves systolic myocardial function in the lateral (free wall): a follow-up study using CMR tissue tagging and 3D strain analysis [PDF]
Aims: Alcohol septal ablation (ASA) has been successful in the treatment of symptomatic hypertrophic obstructive cardiomyopathy (HOCM). The aim of this study is to evaluate the effects of ethanol-induced myocardial infarcts on regional myocardial ...

Septal myectomy: cut, coil, or boil? [PDF]
Hypertrophic cardiomyopathy (HOCM) is characterized by asymmetric septal hypertrophy with outflow tract obstruction in approximately one-third of patients. However, recent studies suggest that obstruction may be present in up to 70% of patients with enhanced sympathetic activation under exercise conditions.1 Clinical features are dyspnoea on exertion ...

Changes in left atrial deformation in hypertrophic cardiomyopathy: Evaluation by vector velocity imaging. [PDF]
OBJECTIVES: Hypertrophic cardiomyopathy (HCM) represents a generalized myopathic process affecting both ventricular and atrial myocardium. We assessed the global and regional left atrial (LA) function and its relation to left ventricular (LV) mechanics ...

Background Transarterial valve intervention (TAVI) is valuable in high-risk patients, however, in case of left ventricular outflow tract (LVOT) obstruction, conventional surgery, including partial myectomy, is indicated.

Hypertrophic obstructive cardiomyopathy: alcohol septal ablation [PDF]
Alcohol septal ablation (ASA) was introduced in 1994 as an alternative to septal myectomy for patients with hypertrophic obstructive cardiomyopathy and symptoms refractory to medical therapy.

Investigating the role of uncoupling of troponin I phosphorylation from changes in myofibrillar Ca(2+)-sensitivity in the pathogenesis of cardiomyopathy. [PDF]
Contraction in the mammalian heart is controlled by the intracellular Ca2+ concentration as it is in all striated muscle, but the heart has an additional signalling system that comes into play to increase heart rate and cardiac output during exercise or ...

ABSTRACT Background A detailed evaluation of hemodynamics, supportive morphology, and deformation may help uncover the pathophysiology of hypertrophic obstructive cardiomyopathy (HOCM) and the changes wrought by alcohol septal ablation (ASA). Purpose To investigate the global cardiac volume, myocardial deformation, and hemodynamic characteristics ...

What is the role of septal myectomy in aortic stenosis?
Asymmetric basal septal hypertrophy is present in 10% of patients with hemodynamic significant aortic valve stenosis. From the surgeon's standpoint, it represents a dilemma as it may be implicated in suboptimal short and long-term results after aortic ...
