Surgical ventricular restoration improves cardiac function in patients with large left aneurysms. Aneurysm repair techniques have evolved to geometric by exclusion of the aneurysmal area a circular patch. But even endoventricular patchplasty may result less elliptical ventricle. We modified both linear and repair. The early intermediate outcomes 102 post-infarction aneurysm, treated between 2001 2004, were analyzed. Concomitant procedures included coronary artery bypass grafting 73 patients,...
OBJECTIVESIn patients with previous myocardial infarction, the remote uninfarcted regions, although contractile, demonstrate dysfunctional wall kinetics because of increased afterload, which improves after surgical ventricular restoration (SVR). We characterized left (LV) mean velocity (MMV) through an analysis endocardial motion and thickening (WT) over cardiac cycle using standard magnetic resonance (cMR).
Clinical outcomes of surgical ventricular restoration (SVR) have been confirmed by Registry data. Accurate assessment left (LV) morphology and function can help optimize these outcomes.LV remodelling in 7 patients (NYHA class 3 ± 1.2) with post-myocardial infarction LV aneurysms was characterized the regional volume (RLVV) computed dividing cine steady-state free precession cardiac magnetic resonance imaging (CMR) at each slice level into six radial segments. Rotation apex base analysed...
OBJECTIVESSeveral issues that are inherent in the surgical techniques of ventricular restoration (SVR) need specialized devices or to overcome them, which may not always result optimal outcomes. We used a non-invasive novel silico modelling technique study left (LV) morphology and function before after SVR. The cardiac magnetic resonance imaging derived actual pre- postoperative endocardial was compared with analysis same.
This pilot study evaluates the association of relative wall thickness (RWT) on survival in patients with ischemic cardiomyopathy (ICM). We hypothesized that preserved RWT may be better candidates for surgical ventricular restoration than those thinner RWT.Echocardiography was performed 165 consecutive (aged 58.2 ± 14.7 years) divided into 2 groups based values. Group 1 had and group reduced RWT.There were 120 (72.7%) hypertension 112 (67.8%) diabetes mellitus. The (group 1) significantly...
Central venous pressure monitoring line insertion is routine prior to the conduct of cardiac surgery, and in rare instances, malposition can contribute operative complications. We describe here how a central lying right atrium became caught left atrial (LA) closure suture during mitral valve replacement. The opening LA highly unsafe without cardiopulmonary bypass (CPB) because possibility systemic air embolism, but by employing an ingenious method suturing over unravelling continuous sutures...
We aimed to evaluate left ventricle twist mechanics in mid-ventricular obstructive and apical type of hypertrophic cardiomyopathy changes induced by myectomy. studied 3 consecutive patients cardiac magnetic resonance preoperatively 6 weeks after calculated the basal rotations at base apex respectively. All underwent myectomy standard described technique. The remained same, while there was an improvement maximal rotation from 0.385 ± 0.3975° 0.9086 1.1751°. In with obstruction hypertrophy, is...
Background In some patients with ischemic cardiomyopathy, despite large increases in ventricular size decreased cardiac output, the paradox of preserved stroke volume has been observed. Following surgical restoration, marked improvements clinically and volumes ejection fraction, a decrease was Methods 101 consecutive postinfarction left aneurysms were studied by 2-dimensional echocardiography contrast ventriculography at baseline, 57 these 1.7 to 2.2 years (mean 1.95 ± 0.44 years) after...
First, the age range of their patients is significantly different to surgical treatment for ischaemic heart failure (STICH) trial [2], being younger by an average 20 years, making direct comparison difficult as pathological entities are probably addressed, albeit same end condition, that is, left ventricular (LV) aneurysm.In Western countries, where STICH trail was based, it found multi-vessel disease producing cardiomyopathy predominant pathology [3].Adhyapak and Parachuri, however, with a...
Abstract The prolate ellipsoid left ventricular geometry is crucial for its unique contraction and relaxation patterns. Perturbations in optimal cardiac function preceding overt heart failure ensue when this shape assumes a more spherical configuration. This stage of configuration, prior to dilatation, therapy should be intensified. dynamic changes during the cycle systole diastole valvular regurgitations volumes are within normal range have proved that clearly dissociated from volume early...
