ABSTRACT
<p><b>OBJECTIVE</b>To compare the safety and efficacy of myocardial contrast enhancement (MCE)-guided and angio-pressure (AP)-guided transcoronary ablation of septal hypertrophy (TASH) for patients with hypertrophic obstructive cardiomyopathy (HOCM).</p><p><b>METHODS</b>TASH was performed under MCE-guide (n = 47, group I) or AP-guide (n = 25, group II) for drug-refractory patients with HOCM. Myocardial perfusion imaging (MPI) data as well as other clinical data were compared.</p><p><b>RESULTS</b>TASH both under MCE-guide or AP-guide resulted in similar and significant reduction of left ventricular outflow tract gradient (PG) and associated with significant symptom improvement (all P < 0.001). Dosage of ethanol use, peak-level of CK-MB and ablated myocardial area and incidence of arrhythmia were also similar between the two groups.Similar left ventricular/atrial dimension changes post TASH were observed in the 2 groups during follow-up. However, the first selected septal vessels were changed under MCE in 6 patients.</p><p><b>CONCLUSIONS</b>Our data demonstrated that the MCE-guided TASH was not superior to AP-guided TASH in safety and efficacy. However, MCE-guided TASH can avoid the misplace of ethanol to avoid innocent myocardial ablation.</p>
