Hands-on training for left heart access

Transseptal puncture is an important technique used by electrophysiologists and interventional cardiologists in the treatment of many cardiac conditions. Although commonly performed, it is not without risk. Over time imaging modalities such as intra-cardiac echo (ICE) and transesophageal echocardiography (TEE) have helped improve the safety of the technique—requiring physicians to adopt a new skillset to understand and interpret these images.

Currently training is performed on patients. Mentice transseptal puncture software takes the training away from the patient and places it in a risk-free environment—allowing physicians to develop and build upon their technical, procedural and cognitive skills. The software provides the user with options to use reference catheters, ultrasound, pressure measurements, and the possibility to show augmented visualizations—putting the focus of the training on safety and ensuring a correct positioning before puncture.

The software allows the user to train as a team with an echocardiographer or individually using preset echo views for ICE and TEE—a key feature within the software. Each scenario has been based on actual clinical cases and provides advanced metrics to help users with a platform upon which they can build procedural success.
