BIOMODEX Technology Enables New Milestone in Interventional Cardiology


Physicians at Montreal Heart Institute used LAACS™ solution to simulate left atrial appendage occlusion, validating the company’s efforts to reduce surgical errors and improve outcomes 

BOSTON, July 21, 2021 — BIOMODEX®, the leader in bio-realistic haptic simulators for patient-specific rehearsal and physician training, today announced that its LAACS™ (Left Atrial Appendage Closure System) solution was used to perform a simulation ahead of a live case to be presented at the TVT Structural Heart Summit in Miami, FL.

Physicians at the Montreal Heart Institute in Montreal, Quebec recently rehearsed the full procedure of a Left Atrial Appendage Occlusion (LAAO) for the first time in North America using a bio-realistic haptic simulator. This breakthrough was achieved by Dr. Reda Ibrahim (interventional cardiologist), Dr. Blandine Mondesert (electrophysiologist), and Dr. Walid Ben Ali (cardiac surgeon) utilizing a 3D-printed replica of the patient’s heart. This replica is part of a novel simulator that delivers realistic catheter navigation, haptic feedback, transesophageal echography, and fluoroscopic imaging.

“Rehearsing a specific case was very helpful—especially one in which we used innovative technologies like the new Abbott Steerable Delivery Sheath for the Amplatzer Amulet occluder, and the transseptal VersaCross Baylis System,” said Dr. Ibrahim. “This realistic simulation allowed us to maximize procedural success and safety.”

For this case, Biomodex printed a 3D patient-specific cardiac anatomy based on the patient’s own CTA images. Models are made of advanced materials that simulate the biomechanical characteristics and haptic feedback of the anatomy. Furthermore, the LAACS station replicates blood flow and viscosity and is ultrasound compatible. The simulation is intended to boost physician confidence, reduce operating times, and decrease the risk of complications. 

Cardiovascular transcatheter therapies have transformed the treatment landscape, expanding options for patients with structural heart disease.

 “Rehearsing these novel approaches using a patient-specific anatomical model is intended to better prepare physicians and potentially improve patient outcomes,” said Ziad Rouag, President and Chief Executive Officer of Biomodex. “It was an honor to support Dr. Ibrahim and his team.”

The rehearsal and subsequent live patient procedure were performed and recorded at the Montreal Heart Institute. Dr. Ibrahim and his team will present their live case at TVT 2021: The Structural Heart Summit on July 22 from 9:30am to 10:10am EDT (LAA Live Case #20: Update of Left Atrial Appendage Occlusion).
