Postoperative atrial fibrillation (AF) occurs frequently after cardiac surgery and contributes significantly to mortality. Transforming growth factor-beta (TGF-β) is associated with postoperative AF after coronary artery bypass grafting and valve surgery. We performed a prospective study to evaluate the role of TGF-β as a predictor of AF after myectomy. A total of 109 consecutive obstructive hypertrophic cardiomyopathy patients without previous AF who underwent myectomy were identified. We measured plasma TGF-β levels before surgery, monitored heart rhythm until discharge, and followed patients for a mean of 36 ± 10 months...

BACKGROUND: Reduced myocardial efficiency represents a target for therapy in hypertrophic cardiomyopathy although therapeutic benefit may depend on disease stage. Here, we determined disease stage-dependent changes in myocardial efficiency and effects of myectomy surgery. METHODS AND RESULTS: Myocardial external efficiency (MEE) was determined in 27 asymptomatic mutation carriers (genotype positive/phenotype negative), 10 patients with hypertrophic obstructive cardiomyopathy (HOCM), 10 patients with aortic valve stenosis, and 14 healthy individuals using [(11)C]-acetate positron emission tomography and cardiovascular magnetic resonance imaging...

We aimed to evaluate left ventricle twist mechanics in mid-ventricular obstructive and apical type of hypertrophic cardiomyopathy and changes induced by myectomy. We studied 3 consecutive patients by cardiac magnetic resonance preoperatively and 6 weeks after myectomy. We calculated the apical and basal rotations at the base and apex respectively. All 3 patients underwent myectomy by the standard described technique. The basal rotations remained the same, while there was an improvement in the maximal apical rotation from 0...

Accurate and reproducible quantification of ventricular septal (VS) thickness in hypertrophic cardiomyopathy (HC) is essential for diagnosis, surgical planning, and risk stratification. We sought to compare VS thickness measurements using transthoracic echocardiography (TTE), transesophageal echocardiography (TEE), and cardiac magnetic resonance (CMR) in patients with HC. Prospectively reported measurements of VS thickness were compared using analysis of variance and Bland-Altman plots in 90 consecutive patients with HC who underwent a TTE, TEE, and CMR within 3 months...

Swallow induced syncope is a rare clinical condition which is thought to result from an abnormal vagal reflex leading to bradycardia and cerebral hypoperfusion. It mostly occurs in patients with organic or functional disorders of the esophagus, and often requires permanent pacemaker implantation, along with treatment of the underlying esophageal pathology. In the following case, we report of a 71-year-old male with achalasia post per oral endoscopic myectomy, who presented with syncope and documented AV-block while eating solid food...

Background and study aims A 54-year-old man was diagnosed with a rectal tumor extending through the submucosal layer. The patient refused surgery and therefore endoscopic submucosal dissection (ESD) was pursued. The lesion exhibited the muscle retraction sign. After dissecting circumferentially around the fibrotic area by double tunneling method, a myotomy was performed through the internal circular muscle layer, creating a plane of dissection between the internal circular muscle layer and the external longitudinal muscle layer, and a myectomy was completed...

A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was whether surgical septal myectomy (SM) is more beneficial than alcohol septal ablation (ASA) in patients with hypertrophic obstructive cardiomyopathy. Altogether 218 articles were found using the reported search, of which 15 studies represented the best evidence to answer the clinical question. There were 14 observational studies and 1 meta-analysis study. The authors, journal, date and country of publication, patient group studied, study type, relevant outcomes and results of these articles are tabulated...

OBJECTIVES: Atrial fibrillation (AF) is common in patients with hypertrophic cardiomyopathy (HCM) and it is often poorly tolerated because of loss of atrial contraction and reduced filling time with rapid ventricular rates. Restoring sinus rhythm is of great clinical benefit to HCM patients. Very few data exist regarding surgical ablation of concomitant AF in this setting. The aim of this study was to evaluate the mid-term outcome of surgical AF ablation in patients who underwent cardiac surgery due to HCM...

BACKGROUND: NT-proBNP level is a predictive factor in hypertrophic cardiomyopathy patients, in which left ventricular outflow tract obstruction contributes to an increased NT-proBNP level. However, studies regarding the influence of septal myectomy on NT-proBNP level in hypertrophic obstructive cardiomyopathy are lacking. METHODS: One hundred and eighty-two patients who underwent septal myectomy in Fuwai Hospital from May 2011 to March 2016 and were included in the present study...

Hypertrophic cardiomyopathy (HCM) is the most common genetic cardiovascular disease characterized by a thickened non-dilated ventricle in the absence of another cardiac or systemic condition. Its most important hemodynamic consequence is left ventricular outflow tract (LVOT) obstruction. The primary management strategy of this condition is surgical septal myectomy, but an acceptable alternative treatment in patients who are not suitable for (or who refuse) surgery is alcohol septal ablation (ASA). However, in patients with unfavorable coronary anatomy which precludes ASA (i...

A Chinese woman was admitted to our hospital because of syncope. Transthoracic echocardiography revealed a hypertrophic basal interventricular septum of 15 mm with a sharp angle protruding into the left ventricular outflow tract. Moreover, an anomalous anterolateral papillary muscle (maximum width of 11 mm) was inserted into the left ventricular outflow tract, with short chordae tendineae connecting both basal interventricular septum and anterior leaflet of the mitral valve. All of these abnormalities resulted in a left ventricular outflow gradient of 136 mmHg...

Spasmodic dysphonia (SD) is rather a rare voice disorder. It is most often seen in woman aged 40-50. The disease is caused by deep emotional and neurological disorders of extrapyramidal system. Two main clinical forms of SD are distinguished: about 90% of cases - adductor spasmodic dysphonia and abductor spasmodic dysphonia roughly 10%. Conservative therapy does not always yield sufficient effects. Botulinum toxin - type A injections into the thyroarytenoid muscle are also used in therapy. Though results are temporary and reversible...
