The prognosis for patients with chronic ischemic left ventricular dysfunction is poor, despite advances in different therapies. Noninvasive assessment of myocardial viability may guide patient management. Multiple imaging techniques have been developed to assess viable and nonviable myocardium by evaluating perfusion, cell membrane integrity, mitochondria, glucose metabolism, scar tissue, and c...

Methods Eighty patients with history of past MI were grouped by MI coronary territory {left anterior descending (LAD), left circumflex (LCX), right coronary (RCA)}. Scar quantification was done by computer-assisted planimetry (Medis Qmass v7.2) of gadolinium enhanced delayed images and MI percentage was determined. Global and regional circumferential subendocardial (Ecc Endo) and subepicardial ...

BACKGROUND Coronary artery disease (CAD) patients are at risk for life-threatening ventricular arrhythmias (VA) related to scar tissue. Late gadolinium enhancement cardiovascular magnetic resonance (LGE-CMR) can accurately identify myocardial scar extent. It has been shown that scar extent, particularly scar transmurality, percent scar and scar mass, are associated with the occurrence of approp...

pregnancy implantation within the scar of a previous cesarean delivery is one of the rarest locations for an ectopic pregnancy. early diagnosis of this condition with the use of ultrasound imaging allows for preserving the uterus and subsequent fertility. however, a delay in either diagnosis or treatment can lead to uterine rupture, hysterectomy and significant maternal morbidity. with increasi...

  Objective (s): Scar formation in injured peripheral nerve bed causes several consequences which impede the process of nerve regeneration. Several animal models are used for scar induction in preclinical studies which target prevention and/or suppression of perineural scar. This study evaluates the translational capacity of four of physical injury models to induce scar formation aro...

Cardiac MRI (CMR) is recognized as an important imaging modality for assessing patients with heart failure. With improved segmentation and image registration tools, data acquired using CMR can help with planning and intraprocedural guidance as well as with defining etiology of heart failure and ventricular function. Here, we describe a successful CRT implantation where segmented CMR images were...

Global longitudinal and circumferential strain was assessed by echo in 15 patients after acute MI. MRI parameters including ventricular volumes, scar, and area at risk were assessed 3+/-2 days post STEMI and at 30 day follow up. Echo strain measures correlated most strongly with LVEF (r=0.81 and 0.88 longitudinal ad circumferential strain, p<0.0001) and infarct size (r=-0.68 and r=-0.69, p<0.00...

Cardiac magnetic resonance imaging (CMR) is a new robust versatile non-invasive imaging technique that can detect global and regional myocardial dysfunction, presence of myocardial ischaemia and myocardial scar tissue in one imaging session without radiation, with superb spatial and temporal resolution, inherited three-dimensional data collection and with relatively safe contrast material. The ...
