Abstract		Based upon the initial clinical experience with PTMR procedure: PTMR is relatively easy to perform, but care need to be exercised to minimize the risk of perforation/effusion. Impressive relieve of Angina was noted. Some patients had hemodynamic improvement as well; and in some patients improvement in the degree of ischemic mitral regurgitation was observed as well. it would be premature to draw conclusions at this point and longer followup periods and more patients are required, however PTMR seems to be effective and probably will serve as an alternative to conventional revascularization techniques. It is important to note that the mechanism of actionof PTMR is not well explained so far. The prevailing thought is that by creating the channels, a network of subendocardial capillaries and neorevascularization provides ischemic relief to the treated area. The possible explanation for the immediate hemodynamic improvement and anginal relief is probably a decrease in subendocardial pressure as well as probably some improvement in diastolic function. The procedure needs to be studied more extensively before final conclusions are drawn. Regardless of mechanism, the procedure seems to be effective of relatively short period of time (up to 1 year), and is probably here to stay.
