Webb2 feb. 2024 · The ventricular outflow tract (OT) is the most common site of origin (SOO) for idiopathic ventricular arrhythmias (VAs) in patients without structural heart disease [ 1, 2, 3 ]. Multiple studies have been shown that radiofrequency catheter ablation (RFCA) can be successfully performed in OT with high success and low complication rates [ 4, 5 ]. A ventricular outflow tract is a portion of either the left ventricle or right ventricle of the heart through which blood passes in order to enter the great arteries. The right ventricular outflow tract (RVOT) is an infundibular extension of the ventricular cavity that connects to the pulmonary artery. The left ventricular outflow tract (LVOT), which connects to the aorta, is nearly indistinguishable from the rest of the ventricle. The outflow tract is derived from t…

Webb30 dec. 2024 · In some cases, it may lead to left ventricular outflow tract (LVOT) obstruction. Systolic ballooning of the AMVT into the outflow tract results in a mass effect and subaortic obstruction, causing symptoms such as exercise intolerance with dyspnea, chest pain, and syncope [ 1 ]. Webb14 apr. 2024 · Pacing from the right ventricular outflow tract (c) Left ventricular epicardial pacing (d) Biventricular pacing. Q12. Time taken for the normal activation of the heart to reach the right ventricular apex is: (a) 0.01 second (b) 0.02 second (c) 0.03 second (d) 0.04 second. Q13.

The Aortic Valve and Left Ventricular Outflow Tract
WebbThe CT examination revealed that the patient had a single large right coronary artery arising from the right sinus of Valsalva, dividing into the right coronary artery, left main coronary artery (LMCA), and left circumflex artery (LCX). The LMCA turned anteriorly in front of the pulmonary outflow tract, reaching the atrioventricular groove. Webb14 apr. 2024 · Ventricular ectopic beats can arise from any part of either ventricle. Those arising from the left ventricle or left side of the interventricular septum produce a right bundle branch block configuration (rsR’ configuration in lead V 1 and the qRS configuration in lead V 6) (Fig. 16.3a).In the presence of anterior myocardial infarction, left ventricular … WebbSo, we carried out this study to determine global systolic dysfunction in patients with HCM.Materials and Methods: A total of 18 patients, diagnosed with HCM according to echocardiography parameters, that is thickness of interventricular septum/posterior wall thickness >1.3 or hypertrophy involving apex only with or without left ventricular outflow … daily grindz townsville
