Core Tip
Core Tip: Anteroseptal focal atrial tachycardia may originate from tissue adjacent to or within the aortic root. When right and left atrial ablation is ineffective or hazardous, systematic mapping of the non coronary cusp can provide a safe and durable cure while minimizing the risk of atrioventricular block.
