Objective To present the authors' 30-year experience with traumatic aortic rupture (TAR). Background Data TAR is a highly lethal injury. Most institutions manage a small number of cases, and most surgeons receive only modest exposure during training.

Objective: We hypothesized that partial cardiopulmonary bypass with a heparin-bonded system would be a technically simple, effective adjunct for reducing paraplegia during repair of traumatic aortic rupture. It avoids the risk of heparin, but, unlike

Traumatic aortic rupture is highly lethal, and its surgical treatment is complicated by a high rate of paraplegia.The charts of 263 patients with traumatic aortic rupture from vehicular accidents treated between 1971 and 1998 were reviewed. Patients

A method is developed and validated for approximating continuous smooth distributions of finite strains in the ventricles from the deformations of magnetic resonance imaging (MRI) tissue tagging "tag lines" or "tag surfaces." Tag lines and intersecti

Background. The pathophysiology of regional mechanical dysfunction in the border zone (BZ) region of left ventricular aneurysm was studied in an ovine model using magnetic resonance imaging tissue-tagging and regional deformation analysis. Methods. T

The effects of direct ventricular interaction and interaction mediated by the pericardium on the diastolic left ventricle (LV) were quantified using idealized models of five pathologic conditions. Two-dimensional (2D) mathematical models were constru

Background A web-based registry was used to prospectively study patients after minimally invasive surgery with monitoring to determine freedom from atrial fibrillation (AF) (clinicaltrials.gov/ct2/show/NCT00747838). This is a report showing the utili

We developed a new animal model of ischemic mitral insufficiency in sheep and used it to test the hypothesis that the combination of posterior papillary muscle infarction and left ventricular dilatation was required to produce mitral regurgitation af

BACKGROUND This study was designed to examine the bulk electrical properties of myocardium and their variation with the evolution of infarction after coronary occlusion. These properties may be useful in distinguishing between normal, ischemic, and i
