Abstract | OBJECTIVE: METHODS: 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. RESULTS: 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. CONCLUSIONS: 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.
