OBJECTIVE To investigate the possible electrophysiological background of the greater excitability of concentric and eccentric left ventricular hypertrophy types in relation to the asymmetric type. METHODS 187 patients with essential hypertension, without ishaemic heart disease were divided into three groups with regard to left ventricule type: concentric (relative wall thickness >0.42, interv...
Hypertrophic obstructive cardiomyopathy (HOCM), the cause of which is unknown, is a heart disease characterized by obstruction of the left ventricular outflow tract and an increase in interventricular septum thickness. Octreotide, a synthetic analogue of somatostatin, was administered subcutaneously to 15 patients for 6 months in order to determine its efficacy in HOCM. Echocardiographic examin...
We observed an unusual case of interventricular septal wall dissection in a patient with a prior myocardial infarction. Echocardiography, magnetic resonance imaging, and left ventriculography revealed separation of the right-side and left-side walls of the interventricular septum with an accessory chamber between the two walls. Morphologic findings were consistent with interventricular septal d...
OBJECTIVES The purpose of this study was to assess the prevalence of the re-entry circuit within the interventricular septum in post-infarction patients referred for ventricular tachycardia (VT) ablation. BACKGROUND Post-infarction ventricular tachycardia can involve the endocardial myocardium, the intramural myocardium, the epicardium, or the His Purkinje system. METHODS Among 74 consecuti...
The roles of posterior bulging of the interventricular septum (septal bulge) and of systolic septal mitral apposition in patients with simple transposition of the great arteries are not known. Cross sectional echocardiograms of 40 such patients were reviewed (after exclusion of those with fixed left ventricular outflow tract obstruction) and haemodynamic findings were compared with long and sho...
INTRODUCTION Visceral fat has deleterious metabolic effects and has been associated with myocardial ischemia. OBJECTIVE To compare epicardial fat thickness in diabetic versus non-diabetic patients with acute myocardial infarction with ST-segment elevation. MATERIAL AND METHODS We performed a cross-sectional study in 60 patients with acute myocardial infarction with ST-segment elevation (30 ...
BACKGROUND We aim to deliver large appliances into the left ventricle through the right ventricle and across the interventricular septum. This transthoracic access route exploits immediate recoil of the septum, and lower transmyocardial pressure gradient across the right versus left ventricular free wall. The route may enhance safety and allow subxiphoid rather than intercostal traversal. MET...
