Objective: To compare the early clinical effect of septal myectomy and percutaneous transluminal septal myocardial ablation (PTMSA) on the left ventricular outflow obstruction and the rate of complication in patients with hypertrophic obstructive cardiomyopathy (HOCM). Methods: A total of 204 patients with HOCM who received septal reduction treatment were recruited. These patients were divided into two groups, surgery group (n=135) (65 patients with modified Morrow procedure, 70 patients with non-Morrow myomectomy) and PTMSA group (n=69)...

Emergent ascending aortic replacement and extended myectomy were performed in a woman with acute aortic dissection who was aged 63 years. Preoperative transthoracic echocardiography performed in the intensive care unit showed only slight left ventricular outflow tract (LVOT) obstruction, but intraoperative transesophageal echocardiography after induction of anesthesia revealed pericardial effusion, systolic anterior motion(SAM), and associated mitral regurgitation(MR). Perioperative SAM and MR are sometimes facilitated under various hemodynamic conditions, but in this case, the left ventricular wall was thick and LVOT appeared to be obstructive by a hypertrophied septum...

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...

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...

CONTEXT: Pheochromocytoma and paraganglioma are rare neuroendocrine tumors which overproduce catecholamines and arise from the adrenal gland or extra-adrenal chromaffin cells of the sympathetic and parasympathetic ganglia (1). Excessive catecholamine-induced stimulation of cardiac myocytes leads to damage which manifests in several forms ranging from Takotsubo to dilated cardiomyopathy. Diagnosis of pheochromocytoma-related cardiomyopathies is often delayed due to the atypical presentation associated with many cases...

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...

After alcohol septal ablation (ASA), regression of left ventricular hypertrophy (LVH) has been observed in several studies using echocardiography or cardiac magnetic resonance, and favorable changes of myocardial excitation have been expected. However, no studies have focused on the alteration of electrocardiography (ECG) findings after ASA. Therefore, we evaluated serial changes in ECG parameters during the chronic phase after ASA for drug-refractory hypertrophic obstructive cardiomyopathy (HOCM). From 1998 to 2014, we performed 187 ASA procedures in 157 drug-refractory HOCM patients...

A 70-year-old woman presented with severe hypertrophic obstructive cardiomyopathy (HOCM) (maximum ventricular septum thickness of 28 mm, peak pressure gradient (PG) in the left ventricular outflow tract (LVOT) of 153 mmHg). We performed percutaneous trans-apex intra-septal radiofrequency ablation (PTAISRA) of the interventricular septum under guidance of transthoracic echocardiography. At six-months follow up, the symptoms were significantly relieved; the septal thickness was reduced to 18 mm and the peak LVOT PG reduced to 44 mmHg...

Despite septal myectomy remaining the gold standard septal reduction therapy for hypertrophic obstructive cardiomyopathy (HOCM), there has been a disproportionate use of alcohol septal ablation (ASA) worldwide. Absolute resolution of left ventricular outflow tract (LVOT) obstruction with ASA is not achieved in a substantial proportion of patients. The mechanisms of failure from ASA are partially understood and described. Residual obstruction in hypertrophic cardiomyopathy is associated with worse clinical outcomes and mortality...
