Think Interventional CRT Physician Education Course

Interventional CRT

Interventional CRT (I-CRT) is an approach that utilizes interventional cardiology tools and techniques to facilitate the implantation of LV leads. The Think Interventional CRT education program uses this combination of tools and techniques to help implanters become proficient, simplifying cases while also providing advanced options for challenging anatomies. Expert faculty utilize didactic presentations and hands-on training to share techniques, including CS cannulation, telescoping, and snaring, which can help improve efficiency and success rates.
