Percutaneous transmural laser revascularization for end-stage ischemia heart diaease / 基础医学与临床

ABSTRACT

Percutaneous myocardial revascularization (PMR)，building on the succeeds of transmyocardial laser revascularization (TMR)，has developed that allows TMR-like channels to be cradated via a percutaneous approach.This catheter based approach avoids the morbidity associated with general anesthesia and thoractomy or thoracoscopy.It also avoids transmural treatment of the myocardium by the laser.Although its mechanism remains unclear,many patients with intractable angina and non-bypassable coronary artery disease have benefited from the new system.It is hoped that PMR will mimic the clinical benefit of TMR，and will gradually become a main method in treating end-staged coronary artery disease.
