|
E.2.2 | Secondary objectives of the trial |
To assess the concordance between stress CMR without contrast using myocardial native T1 maps and conventional stress CMR with contrast for the detection of ischemia in patients with coronary CTO. To compare the modification of the arrhythmogenic substrate, both myocardial ischemia and the characterization of CMR Myocardial Scarring Before and After Percutaneous Revascularization of Coronary CTO. |
Evaluar la concordancia entre la RMC de estrés sin contraste mediante mapas de T1 nativo miocárdico y la RMC de estrés convencional con contraste para la detección de isquemia en pacientes con CTO coronaria.Comparar la modificación del sustrato arritmogénico, tanto la isquemia miocárdica como la caracterización de la cicatriz miocárdica mediante la RMC antes y después de la revascularización percutánea de una CTO coronaria. |
