Apical ballooning syndrome or aborted acute myocardial infarction? Insights from cardiovascular magnetic resonance imaging.
Apical Ballooning Syndrome (ABS) is a novel acute cardiac syndrome that mimics acute myocardial infarction (AMI). This study evaluates the diagnostic utility of cardiac magnetic resonance imaging (CMR) in patients with suspected ABS. ⋯ While ABS mimics AMI, AMI with spontaneous clot lysis may also mimic ABS, and at least in some patients, be mistaken for ABS. ABS is characterized by the absence of MDE and complete myocardial viability on CMR. The diagnosis of ABS can be excluded if CMR demonstrates MDE consistent with myocardial necrosis in a pattern and distribution consistent with AMI.
