Abstract
Summary
Ten mongrel dogs have been subjected to experimental ligation of major branches of the anterior descending trunk of the left coronary artery. The infarcted areas have been removed by a closed technic and replaced by a teflon felt prostheses. All of the animals have survived. Two were sacrificed one week following the operation, while eight others are now being followed for periods of up to four months. They will be sacrificed at the end of a year.
To this time, the implanted material appears to be well tolerated by the myocardium.
