A week later, we performed left lateral thoracotomy and injected adenovirus carrying complementary DNA encoding CCNA2 or null adenovirus into peri-infarct myocardium.

In the pulmonary and carotid arteries, in the vena cavas and myocardium, there were extensive necroses and hyaline degeneration.

Temporary propagation block throughout the ventricular myocardium could possibly terminate these arrhythmias.
