Radiofrequency ablation is a promising procedure for treating atrial fibrillation (AF) that relies on accurate lesion delivery in the left atrial (LA) wall for success. Late Gadolinium Enhancement MRI (LGE MRI) at three months post-ablation has proven effective for noninvasive assessment of the location and extent of scar formation, which are important factors for predicting patient outcome and...
BACKGROUND The relationship between cardiac contrast-enhanced magnetic resonance imaging (CE-MRI)-derived scar characteristics and substrate for ventricular tachycardia (VT) in patients with structural heart disease (SHD) has not been fully investigated. METHODS This study included 51 patients (mean age, 63.3±15.1 years) who underwent CE-MRI with SHD and VT induction testing before ablation. ...
SCAR SCATTER, CONCEAL AND RECOVER Bryan Mills, M.S. University of Pittsburgh, 2007 This thesis describes a secure and reliable method for storing data in a distributed hash table (DHT) that leverages the inherent properties of the DHT to provide a secure storage substrate. The framework presented is referred to as “Scatter, Conceal, and Recover” (SCAR). The standard method of securing data in a...
Methods Patients (n = 337) with ≥ 70% disease in ≥1 epicardial coronary artery (77% men, median age 66 years, median LV ejection fraction [EF] of 22 %) undergoing CMR (Siemens 1.5-T scanner, Erlangen, Germany) between 2003-2007 were studied. CMR evaluation included long and short axis assessment of LV function on steady state free precession cine images along with assessment of myocardial scar ...
Cesarean scar pregnancy (CSP) is a rare, but life-threatening type of ectopic pregnancy. An exact and early diagnosis of CSP is very important for prognosis. The aim of the present study was to describe 4 women with CSP and discuss their clinical presentations, diagnoses, and various management options along with the published literature. Four women with a suspicion of CSP or cervical pregnancy...
Myocardial infarction (MI) induces neural and electrical remodeling at scar border zones. The impact of focal MI on global functional neural remodeling is not well understood. Sympathetic stimulation was performed in swine with anteroapical infarcts (MI; n = 9) and control swine (n = 9). A 56-electrode sock was placed over both ventricles to record electrograms at baseline and during left, righ...
