LABORATORY work has demonstrated that a small knife can be passed into the lumen of a coronary artery to slice longitudinally the visceral surface of that artery. This results in a "coronary-myocardial artery" which assumes approximate normal size with at least one half of the wall composed of fibrous tissue lined with intima.1-3 In an attempt to relate this laboratory phenomena to clinical stenotic coronary artery disease, the following experiments were performed.

Experimental Procedure  Fourteen mongrel dogs were subjected to a standardized thoracotomy. In an initial procedure, a cotton 0 suture swaged on a needle was passed within the lumen of the anterior descending coronary artery for approximately 1 cm. Bleeding was controlled by previously placed epicardial purse-string sutures and the chest was closed (Fig 1).Nine of the ten animals which survived the initial operation were reoperated on between 56 and 91 days (average 76.3 days).
