Septal myectomy: cut, coil, or boil? [PDF]

European Heart Journal, 2008
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 ...

Percutaneous septal ablation for left mid-ventricular obstructive hypertrophic cardiomyopathy: a case report [PDF]

, 2006
Background Mid-ventricular obstructive hypertrophic cardiomyopathy (MVOHC) is a rare type of cardiomyopathy. The diagnosis is based on the hourglass appearance on the left ventriculogram and the presence of pressure gradient between apical and basal ...

Sutureless Aortic Valve Replacement in a Patient with Transfemoral Aortic Valve Replacement and Left Ventricular Hypertrophy

The Thoracic & Cardiovascular Surgeon Reports, 2015
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.

Changes in left atrial deformation in hypertrophic cardiomyopathy: Evaluation by vector velocity imaging. [PDF]

, 2012
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 ...

Hypertrophic obstructive cardiomyopathy: alcohol septal ablation [PDF]

, 2017
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.

Beat‐to‐beat variability of ventricular repolarization reveals sex‐specific instability and proarrhythmic risk

The Journal of Physiology, EarlyView.
Abstract figure legend A mechanistic framework linking sex‐dependent dynamical instability to proarrhythmic risk. Sex‐specific human ventricular models show that upstream modulators, including biological sex, hormones, drugs and heart disease, promote steeper APD restitution in female than male and enhance dynamical instability.

Efficacy and safety of myectomy and radiofrequency septal ablation for treating hypertrophic obstructive cardiomyopathy

Open Heart
Background Novel treatments are needed for patients with severely symptomatic obstructive hypertrophic cardiomyopathy (oHCM). Radiofrequency (RF) septal ablation has emerged as a promising technique for improving the left ventricular outflow tract (LVOT)

Systolic anterior motion of the mitral valve associated with acute type A aortic dissection: a case report describing one-step surgery of ascending aortic replacement and interventricular septal myectomy

Surgical Case Reports, 2021
Background Systolic anterior motion of the mitral valve associated with acute type A aortic dissection is rare in daily clinical practice. The prevention of systolic anterior motion is important, because once it occurs, the hemodynamics may become ...

Investigating the role of uncoupling of troponin I phosphorylation from changes in myofibrillar Ca(2+)-sensitivity in the pathogenesis of cardiomyopathy. [PDF]

, 2014
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 ...
