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...

Septal reduction therapy is the gold standard treatment method for symptomatic, hypertrophic obstructive cardiomyopathy. Although surgical myectomy is a well-established and effective technique with decades of experience in its application, use of transcoronary alcohol septal ablation has increased precipitously owing to the less-invasive nature of the procedure. Moreover, endocardial septal ablation therapy is a relatively newly defined modality, and outcomes of the procedure are not clearly elucidated yet...

INTRODUCTION AND PURPOSE: We describe the clinical characteristics of 252 patients with unilateral superior oblique palsy who underwent strabismus surgery. We assess if a predetermined surgical strategy, based on preoperative alignment and motility measurements, was effective in treating these patients. On this basis, the patients were divided into three different treatment groups. METHODS: Two-hundred fifty-two patients were identified retrospectively and classified into three groups according to the performed procedures: 1) inferior oblique weakening; 2) inferior rectus recession; 3) combined inferior oblique weakening and inferior rectus recession...

OBJECTIVE: Alcohol septal ablation (ASA) is a therapeutic alternative to surgical myectomy in patients with hypertrophic obstructive cardiomyopathy (HOCM). However, the anatomical variability of the septal branch, risk of complete heart block, and late onset ventricular arrhythmias are limitations to its therapeutic usage. There is recent interest in the use of radiofrequency catheter ablation (RFCA) as a therapeutic option in HOCM. We aimed to assess the safety and efficacy of RFCA in the treatment of symptomatic HOCM...

OBJECTIVE: Static 3-dimensional printing is used for operative planning in cases that involve difficult anatomy. An interactive 3D print allowing deliberate surgical practice would represent an advance. METHODS: Two patients with hypertrophic cardiomyopathy had 3-dimensional prints constructed preoperatively. Stereolithography files were generated by segmentation of chest computed tomographic scans. Prints were made with hydrogel material, yielding tissue-like models that can be surgically manipulated...

Septal reduction therapy is accepted as a first therapeutic option for symptomatic drug-resistant hypertrophic obstructive cardiomyopathy (HOCM). Although, surgical septal myectomy is the gold standard method, alcohol septal ablation is a well-studied alternative approach in the patients with suitable anatomy. Endocardial septal ablation (ESA) therapy was relatively new defined modality and outcomes of the procedure were not clearly elucidated yet. We aimed to review the clinical aspects of ESA procedure and provide some historical background...

OBJECTIVES: Investigate the effectiveness of alcohol septal ablation (ASA) and transaortic extended myectomy (TEM) in hypertrophic cardiomyopathy (HCM) with midventricular obstruction (MVO). BACKGROUND: MVO is less common than subaortic obstruction. Data on the effectiveness of ASA and TEM in MVO are lacking. METHODS: The clinical profiles of 22 patients undergoing ASA and 37 patients undergoing TEM were compared. No patient had apical aneurysm, abnormal chordae, mitral valve replacement or repair...

Subaortic diaphragm is characterized by a certain clinical latency and low morbi-mortality. Surgery remains the treatment of choice despite the real risk of long-term recurrence. Our study involved 18 patients with subaortic diaphragm operated between April 1994 and March 2011. The average age was 18.1 ± 9.7 years, 11 patients were male. The diaphragm was fibrous in 13 patients and fibromuscular in 5 patients. All patients underwent diaphragm resection associated with myectomy, aortic plasty, closure of ventricular septal defect and permeable ductus arteriosus ligation in 3, 3, 2 and 2 patients respectively...

Acromegaly is a rare disease, mostly caused by a growth hormone (GH)-secreting benign pituitary tumor, with an increased production of GH and insulin-like growth factor 1 (IGF-1). Cardiovascular complications are common and are associated with cardiomyocyte apoptosis and concentric cardiac hypertrophy. Suppression of GH and IGF-1 appears to improve cardiac function only in the short term, with little or no decrease in left ventricular mass or improvement in cardiac function after prolonged treatment. Alcohol septal ablation (ASA) has emerged as a minimally invasive alternative to septal myectomy, with significant improvement in symptoms, gradients and left ventricular remodeling...

IMPORTANCE: Previous data on septal myectomy (SM) and alcohol septal ablation (ASA) in obstructive hypertrophic cardiomyopathy have been limited to small, nonrandomized, single-center studies. Use of septal reduction therapy and the effect of institutional experience on procedural outcomes nationally are unknown. OBJECTIVE: To examine in-hospital outcomes after SM and ASA stratified by hospital volume within a large, national inpatient database. DESIGN, SETTING, AND PARTICIPANTS: This study analyzed all patients who were hospitalized for SM or ASA in a nationwide inpatient database from January 1, 2003, through December 31, 2011...

Hypertrophic cardiomyopathy (HCM) is a relatively common genetic heart disease encumbered throughout much of its almost 60-year history by a large measure of misunderstanding and the perception of a grim outcome without effective treatment options. However, it is now apparent that the majority of patients affected with HCM can achieve normal or near-normal life expectancy without disability, and usually do not require major treatment interventions. Nevertheless, for those patients with HCM who are at risk for (or experience) disease-related complications, a constellation of comprehensive nonpharmacologic management strategies have evolved over the last 15 years, altering the natural history and disease course for many, including implantable defibrillators, heart transplant, external defibrillation/therapeutic hypothermia, advances in surgical myectomy, and alcohol ablation...

BACKGROUND: Systolic anterior motion (SAM) of the mitral valve, left ventricular outflow tract (LVOT) obstruction, and mitral regurgitation (MR) are known adverse outcomes that can occur after septal myectomy for hypertrophic obstructive cardiomyopathy. The objective of this study was to describe outcomes of a surgical technique to prevent these complications. METHODS: We have adopted a technique where we place an Alfieri stitch in the mitral valve through the aortotomy while performing septal myectomy...

Retrospective comparison of alcohol septal ablation with surgical myectomy suggests that although there is a greater reduction in LVOT gradient with surgical myectomy, symptom relief and survival are similar between the two treatment strategies. In patients who don't have an anatomic indication for surgical myectomy, alcohol septal ablation appears to be a safe and effective alternative. Patients with medication-refractory HOCM require a multi-disciplinary assessment, which is best performed at specialized treatment centers, to assess which therapy is best suited to treat them...
