Task: Answer Verification
Input (English): Question: Do laser-mediated transmural myocardial channels salvage acutely ischemic myocardium?
Answer: Direct laser revascularization of the heart did not provide any immediate benefit to ischemic myocardium in this canine model of coronary artery occlusion. Thus, it is doubtful that direct laser-mediated myocardial revascularization would be of immediate benefit in the treatment of patients with acute ischemia.
Output (English): no
