Hypertrophic cardiomyopathy is the most common genetically transmitted heart disease. Around two-thirds of patients develop symptoms caused by the dynamic left ventricular outflow tract obstruction, either at rest or during effort. For patients with hypertrophic obstructive cardiomyopathy (HOCM) that remain symptomatic despite optimal medical treatment, septal reduction is a valuable therapeutic strategy. While surgical myomectomy was considered the gold standard until the end of the 1990s, alcohol septal ablation (ASA) has gained rapid popularity and acceptance, especially in Europe...

AIMS: Percutaneous septal reduction therapy by either alcohol or nonalcohol agents is an alternative approach to surgery in drug-refractory symptomatic patients with hypertrophic obstructive cardiomyopathy (HOCM). Nonalcohol agents have some advantages and disadvantages over alcohol during the procedure. Nowadays, a novel non-alcohol agent, named as Ethylene-vinyl alcohol (EVOH) copolymer (Onyx® and Squid® ), is used during septal ablation. Thus, in this study, we aimed to evaluate both acute and long-term efficacy and safety profile of EVOH during septal ablation in HOCM...

Papillary fibroelastomas (PFEs) are one of the most frequent primary cardiac tumors and occur more often in patients with hypertrophic obstructive cardiomyopathy (HOCM). PFEs have been linked to an increased risk of neurological events. We report a case of a 59-year-old woman with HOCM in whom echocardiography (transthoracic and transesophageal, using 2D and 3D techniques) revealed multiple masses in various locations in the left cardiac chambers. Surgical excision of the cardiac tumors and aortic valve replacement was performed and the pathologic report confirmed the diagnosis of PFEs...

OBJECTIVES: Patients with hypertrophic obstructive cardiomyopathy and basal septal thickness <18 mm are often considered unsuitable candidates for myectomy. Mitral valve (MV) replacement is frequently performed instead. We aimed to determine whether septal thickness affects outcomes and adequacy of myectomy. METHODS: Clinical and echocardiographic data were reviewed for 1486 consecutive adult patients with hypertrophic obstructive cardiomyopathy who underwent transaortic septal myectomy from January 2005 through December 2014...

BACKGROUND: The purposes of this study were to assess the usefulness of myocardial 18F-fluorodeoxyglucose (18F-FDG) positron emission tomography (PET)/computed tomography (CT) for evaluating myocardial metabolic status in hypertrophic cardiomyopathy (HCM) and the therapeutic efficacy of alcohol septal ablation (ASA) in hypertrophic obstructive cardiomyopathy (HOCM). METHODS: Thirty HCM patients (64.4±10.5 years, 14 male, 12 hypertrophic non-obstructive cardiomyopathy [HNCM], 16 HOCM, and 2 dilated phase of HCM) underwent 18F-FDG-PET/CT...

Coronary postmortem computed tomography angiography (coronary PMCTA) has been introduced as a routine examination procedure for autopsy at our department. Here, we reviewed eight autopsy cases in which apparent histopathological changes including acute myocardial infarction (AMI), anomalous aortic origin of a coronary artery (AAOCA), hypertrophic obstructive cardiomyopathy (HOCM) and acute myocarditis were involved in the cause of death. For investigation of the coronary artery and shape of the heart, coronary PMCTA was valuable in detecting narrowing or obstruction of coronary artery in AMI, indicating an anomalous aortic origin of the left coronary artery in AAOCA, and demonstrating septal hypertrophy and intracavitary obstruction in HOCM...

Aims: We aimed to identify a novel biomarker involved in the early events leading to an acute coronary syndrome (ACS) and evaluate its role in diagnosis and risk stratification. Methods and results: Biomarker identification was based on gene expression profiling. In coronary thrombi of ACS patients, cysteine-rich angiogenic inducer 61 (Cyr61, CCN1) gene transcripts were highly up-regulated compared with peripheral mononuclear cells. In a murine ischaemia-reperfusion model (I/R), myocardial Cyr61 expression was markedly increased compared with the controls...

Both surgical myectomy and percutaneous transluminal septal myocardial ablation are effective treatments for drug-refractory symptomatic hypertrophic obstructive cardiomyopathy (HOCM). However, in some cases, it is not easy to elucidate the abnormal structure of left ventricular outflow obstruction to adopt these treatments. Here, we presented a young female patient with drug-refractory symptomatic HOCM. In this case, contrast-enhanced computed tomography enabled us to assess the suitability of percutaneous transluminal septal myocardial ablation...

OBJECTIVES: Residual midventricular obstruction after transaortic myectomy may lead to recurrent symptoms and reoperation in patients with hypertrophic cardiomyopathy and long-segment septal hypertrophy. A combined transaortic and transapical approach to septal myectomy during initial operation allows for the complete relief of subaortic and midventricular gradients and may reduce the risk of poor late functional results. METHODS: We analyzed the early outcomes of 86 patients aged 18 years or more who underwent combined transaortic and transapical septal myectomy for left ventricular outflow tract obstruction due to systolic anterior motion and midventricular obstruction or cavitary obliteration due to apical hypertrophic cardiomyopathy...

Hypertrophic cardiomyopathy is the most common inherited cardiovascular disease. It is characterized by increased ventricular wall thickness and is highly complex due to its heterogeneous clinical presentation, several phenotypes, large number of associated causal mutations and broad spectrum of complications. It is caused by mutations in sarcomeric proteins, which are identified in up to 60% of cases of the disease. Clinical manifestations of Hypertrophic Cardiomyopathy include shortness of breath, chest pain, palpitations and syncope, which are related to the onset of diastolic dysfunction, left ventricular outflow tract obstruction, ischemia, atrial fibrillation and abnormal vascular responses...

Over the last 25 years, patients with hypertrophic cardiomyopathy (HCM) have been studied with a variety of methods employing physiological exercise that have made major contributions to disease management and are performed without increased risk. Previously under-utilized in HCM, exercise (stress) echocardiography has become incorporated into the standard clinical assessment and diagnostic armamentarium of HCM using upright or supine symptom-limited treadmill or bicycle modalities. In patients without outflow gradients at rest, exercise echocardiography is the most appropriate method for provoking obstruction, with the capability of predicting future development of progressive heart failure symptoms, and differentiating patients with provocable obstruction from those without obstruction, with major implications for dictating treatment options, that is, surgical myectomy (alternatively, alcohol septal ablation) versus heart transplant...

Objective: To establish which risk factors are predictive for sudden death in hypertrophic cardiomyopathy (HCM) diagnosed in childhood. Methods: A Swedish national cohort of patients with HCM diagnosed <19 years of age was collected between 1972 and 2014, consisting of 155 patients with available ECGs, with average follow-up of 10.9±(SD 9.0) years, out of whom 32 had suffered sudden death or cardiac arrest (SD/CA group). Previously proposed risk factors and clinical features, ECG and ultrasound measures were compared between SD/CA group and patients surviving >2 years (n=100), and features significantly more common in SD/CA group were further analysed with univariate and multivariate Cox hazard regression in the total cohort...

Systolic anterior motion (SAM) of the mitral valve or chordate is one characteristic seen in hypertrophic cardiomyopathy (HCM) either in obstructive or non-obstructive phenotypes. More often than not, the obstruction is caused by valvular rather than chordal SAM. We describe the role of echocardiography in identifying the actual anatomical location of the mitral valve apparatus involved in SAM and in assessing consequent left ventricular outflow tract (LVOT) obstruction in an otherwise asymptomatic patient...

In hypertrophic cardiomyopathy (HCM) patients with symptoms caused by left ventricular outflow tract obstruction (LVOTO), treatment options include negative inotropic drugs, myectomy, septal alcohol ablation and AV sequential pacing with or without an implantable cardioverter defibrillator (ICD). Pacing is rarely used in spite of its relative simplicity and promising results. In this review the current evidence of AV sequential pacing from observational, randomised studies and long and very long-term follow-up studies is given and put in the context of present guidelines recommendations...
