Septal reduction therapy (SRT) is the accepted therapeutic option for symptomatic hypertrophic obstructive cardiomyopathy (HOCM). At this time, surgical septal myectomy is the gold standard method, but alcohol septal ablation is an acceptable alternative treatment for patients with suitable anatomy. Endocardial septal ablation (ESA) therapy is a little-known method of SRT. Presently described is case of successful ESA procedure performed for HOCM.

INTRODUCTION: Partial resection of the septal muscle is a well-established and effective method of surgical treatment for patients with hypertrophic obstructive cardiomyopathy (HOCM). The procedure is characterized by a low operative mortality rate and long-term clinical improvement that has been confirmed in numerous publications. Mitral insufficiency in patients with HOCM is mostly functional due to the effect of systolic anterior motion (SAM). AIM: To present the early results of surgical treatment provided to HOCM patients and to compare the effectiveness of two surgical procedures: isolated myectomy and myectomy combined with mitral valve replacement...

OBJECTIVES: Current nonpharmacological therapies for symptomatic patients with hypertrophic obstructive cardiomyopathy (HOCM), including septal myectomy and alcohol septal ablation (ASA), carry significant risks for serious cardiac conduction abnormalities. We present a review of the currently available published data regarding the novel use of the relatively low-risk MitraClip® system in the treatment of symptomatic patients. METHODS: Data were collected from 4 separate studies on the use of the MitraClip on 15 symptomatic HOCM patients with systolic anterior motion (SAM) of the mitral valve apparatus...

The current trend to treat hypotension in critically ill patients is to place a greater emphasis on inotropic support and less on fluid resuscitation in order to limit the potential harm from fluid overload. This combination may trigger left ventricular outflow tract obstruction (LVOTO) in susceptible patients. Although LVOTO is classically described in patients with hypertrophic cardiomyopathy it has been reported in other conditions including septic shock, apical ballooning syndrome, myocardial infarction, respiratory failure, and post valvular surgery...

PURPOSE: The clinical differentiation between athlete's heart and mild forms of non-obstructive hypertrophic cardiomyopathy (HCM) is crucial. We hypothesized that differences do exist between the myocardial metabolism of patients with non-obstructive HCM and competitive athletes (CAs). Our aim was to evaluate myocardial metabolism with (31)P-MRS and (1)H-MRS in HCM patients and CAs. MATERIALS AND METHODS: After Ethics Committee approval, 15 CAs and 7 HCM patients were prospectively enrolled...

Currently, two therapeutic options are available for patients with drug-resistant obstructive hypertrophic cardiomyopathy. While there is a tendency in extended myectomy to perform a larger septal reduction to eliminate left ventricular outflow tract gradient more effectively, there has been a trend in recent years toward using lower dosages of alcohol during alcohol septal ablation (ASA) to reduce the risk of arrhythmic complications. We report a case of a symptomatic patient with severe septal hypertrophy who underwent an extended ASA of three septal branches...

AIMS: Our goal was to identify the prevalence of aortic dilation in patients with hypertrophic cardiomyopathy (HCM), the most prevalent (0.2%) heritable, genetic cardiovascular disease. Aortic dilation also represents a spectrum of familial inheritance. However, data regarding the prevalence of aortic dilation in HCM patients is lacking. METHODS AND RESULTS: This is an observational retrospective study of all patients referred to our HCM centre. Aortic dilation was defined based on recent American Society of Echocardiography and European Association of Cardiovascular Imaging published guidelines...

Pregnancy in women with hypertrophic cardiomyopathy (HCM) is associated with a slightly increased risk of maternal morbidity and mortality, as well as a higher risk of premature births. One of the risk factors complicating pregnancies in HCM is left ventricular outflow tract obstruction (LVOTO). We report a case of a symptomatic patient with HCM and LVOTO who was treated with alcohol septal ablation and then had an uncomplicated pregnancy.

Background Hypertrophic cardiomyopathy is a genetic disease of the myocardial sarcolemma characterized by left ventricular hypertrophy. When obstruction to the left ventricular outflow tract is present and symptoms are refractory to medication, surgical myectomy or alcohol septal ablation is indicated. Case Description We report a case of a patient presented for myectomy due to recurrence only 1 year after alcohol ablation. Interesting findings were a firm subaortic membrane and a direct insertion of the papillary muscle into the mitral valve...

Sustained ventricular tachycardia complicating left ventricular apical aneurysms has been reported previously solely in middle-aged patients with hypertrophic cardiomyopathy and mid-cavity obstruction. We report a case of an elderly female patient who presented with incessant ventricular tachycardia as the first clinical manifestation of hypertrophic cardiomyopathy with mid-ventricular obstruction and apical aneurysm.

Several genetic conditions can lead to left ventricular hypertrophy (LVH). Among them, hypertrophic cardiomyopathy (HCM), caused by mutations in sarcomere genes, is the most common inherited cardiac disease. Instead, RASopathies, a rare class of disorders characterized by neuro-cardio-facial-cutaneous abnormalities and sometimes presenting with LVH, are caused by mutations in the RAS-MAPK pathway. We report on a 62-years-old male who presented isolated severe obstructive LVH but did not carry the sarcomere mutation previously identified in his affected relatives...

Hypertrophic cardiomyopathy (HCM) is an inherited disease of the heart muscle characterized by otherwise unexplained thickening of the left ventricle. Left ventricular outflow tract (LVOT) obstruction is present in approximately two-thirds of patients and substantially increases the risk of disease complications. Invasive treatment with septal myectomy or alcohol septal ablation can improve symptoms and functional status, but currently available drugs for reducing obstruction have pleiotropic effects and variable therapeutic responses...

Diabetes mellitus represents the most common medical condition causing complications during pregnancy. However, there is still some controversy surrounding complications. Maternal hyperglycemia leads to fetal hyperglycemia. Offspring of diabetic mothers compensate excess glucose concentrations by producing higher levels of insulin causing transient hyperinsulinemia. Infants of diabetic mothers are at risk for congenital cardiac malformations, of which 40% are with hypertrophic cardiomyopathy. However, regardless of severity, cardiac hypertrophy is transient with echocardiographic resolution within the first months after birth...

Hypertrophic obstructive cardiomyopathy is an inherited myocardial disease defined by cardiac hypertrophy (wall thickness ≥15 mm) that is not explained by abnormal loading conditions, and left ventricular obstruction greater than or equal to 30 mm Hg. Typical symptoms include dyspnoea, chest pain, palpitations, and syncope. The diagnosis is usually suspected on clinical examination and confirmed by imaging. Some patients are at increased risk of sudden cardiac death, heart failure, and atrial fibrillation...
