Does the Transradial Approach for ASA Offer Better Prognosis?

Alcohol septal ablation (ASA) is a percutaneous procedure used to avoid open heart surgeries in patients with hypertrophic obstructive cardiomyopathy . A thin catheter is introduced into the thickened heart muscles , and alcohol is injected either through the femoral or radial artery approach. Conventionally, the femoral artery approach is the most used method. Now, researchers from the Medical University of South Carolina have evaluated the success, reduction in left ventricular outflow tract gradient (LVOTG), contrast volume, fluoroscopy time, and complications of the transradial approach versus the transfemoral artery approach for ASA.

Findings that suggest better outcomes with the transradial approach No difference in resting LVOTG (91% vs. 92%; p=.50) Lesser vascular complications (0.13 vs. 0.23; p=.04) Contrast volume was significantly lower in the transradial group (98 mL vs.…
