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...

BACKGROUND The segmental relationship between cardiovascular magnetic resonance (CMR) peak circumferential strain (Ecc) and myocardial scar has not been well characterized in Duchenne muscular dystrophy (DMD), and it is unknown whether echocardiography accurately measures Ecc in DMD. We assessed segmental Ecc and scar using CMR with myocardial tissue tagging and late gadolinium enhancement (LGE...

Late wound management requires not only mastery of the techniques involved in scar revision, but a thorough understanding of facial anatomy, wound healing, and the psychological factors associated with traumatic injury. Treatment of a patient for scar revision requires the surgeon to understand that a patient’s perception of a scar is often influenced by emotionally charged circumstances and po...

Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), and drug reaction with eosinophilia and systemic symptoms (DRESS) are severe cutaneous adverse reactions (SCAR) which are majorly caused by drugs. Though the incidence rate is low, SCAR sometimes can be life-threatening and leads to lifelong sequelae. Many pharmacogenomic associations in immune and nonimmune related genes with th...

A Z-plasty is a critical and reliable technique that is useful for scar revisions and correction of free margin distortion. A Z-plasty can help lengthen a contracted scar, change the direction of a scar so that it is better aligned with the relaxed skin tension lines, or interrupt and break a scar for better camouflage. This article will review the technique of a basic Z-plasty as well as provi...

BACKGROUND The aim of the study was to perform a feature tracking analysis on cine magnetic resonance (MR) images to elucidate if functional measurements of the motion of the left ventricular wall may detect scar defined with gadolinium enhanced MR.Myocardial contraction can be measured in terms of the velocity, displacement and local deformation (strain) of a particular myocardial segment. Con...

BACKGROUND A left bundle-branch block (LBBB)-like pattern with a dominant S-wave in V(1) is common in idiopathic ventricular arrhythmias (VA). Discrimination between idiopathic and scar-related LBBB pattern VA has important clinical implications. We hypothesized that the VA QRS morphology is influenced by the presence of ventricular scar, allowing ECG discrimination of VA arising from structura...
