A novel, minimally invasive, segmental myocardial infarction with a clear healed infarct borderzone in rabbits

A novel, minimally invasive, segmental myocardial infarction with a clear healed infarct borderzone in rabbits.

Ventricular arrhythmias in the setting of a healed myocardial infarction have been studied to a much lesser degree than acute and subacute infarction, due to the pericardial scarring, which results from the traditional open-chest techniques used for myocardial infarction (MI) induction. We sought to develop a segmental MI with low perioperative mortality in the rabbit that allows optimal visual...

Ventricle With Healed Myocardial Infarction

Cellular electrophysiological consequences of acute ischemia superimposed on healed myocardial infarction were studied in isolated, coronary-perfused cat left ventricles 2-4 months after ligation of multiple distal tributaries of the left anterior descending and circumflex coronary arteries. Oxygenated Tyrode's solution was perfused through the left anterior descending and circumflex coronary a...

Minimally invasive total splenectomy in dogs: A clinical report

Cases of minimally-invasive surgery are gaining acceptance among surgeons and animal owners. One type of minimally-invasive surgery is total splenectomy, which is indicated for splenic tumors, trauma, torsions, and for dogs that require blood transfusion. To assess the safety of the technique, experimental laparoscopic splenectomies were performed in dogs for the first time in Iran. Three adult...

Activation patterns in healed experimental myocardial infarction.

The maximum amplitude of vector loops formed by summing orthogonally recorded bipolar electrograms has been shown to reflect the direction of activation in cardiac muscle. To investigate whether components of vector loops could provide information about different activation directions in local areas of myocardium, we correlated "instantaneous vectors" with isochronal activation patterns in an i...
