Efficacy and outcome of transmyocardial revascularization [TMR]: initial egyptian experience

ABSTRACT

In this study, 37 patients [with age 52 +/- 10.1, 31 males and 6 females] with severe coronary artery disease [CAD] and intractable angina were subjected to TMR. Nineteen patients had prior myocardial infarction [MI]. The mean angina class was 3.4 +/- 0.5. All patients were subjected to stress-redistribution reinjection [ST-RD-RI] Thallium SPECT protocol and rest 99 mTc-RBG MUGA just before, 3, 6, 9 and 12 months after TMR, aiming to assess the degree of change in perfusion in the ischemic area using semiquantitative score [I = normal and 4 = absent uptake] and to assess the function. The study concluded that TMR can be used effectively in cases of severe CAD, which could not be managed by either CABG or PTCA. Myocardial perfusion imaging is a good method to assess TMR results:
