Transseptal Puncture

Realistic and Comprehensive Training of the Transseptal Puncture Procedure

Watch the product release webinar on demand >

Transseptal puncture is used by electrophysiologists and interventional cardiologists to gain access through the fossa ovalis to the left atrium to treat different cardiac conditions. This module complements fluoroscopy with ultrasound imaging modalities, intra-cardiac echo (ICE) and transesophageal echocardiography (TEE), to help improve the success of the procedure. The software provides options to use ultrasound, pressure measurements, and the possibility to show augmented visualizations, to ensure a safe and precise puncture.

Mentice clinical modules take training away from patients and animals – allowing physicians to develop and build their technical, procedural, and cognitive skills in a realistic and risk-free environment.

Features & Benefits

Transseptal Puncture is critical in many interventions, and opportunities to practice it in the clinical setting are limited. This solution combines practical exercises and E-learning which, supported by Augmented Reality goes beyond what can be done in traditional practice, offering - 

  • Complete TSP course with e-learning and practical exercises

  • Training on ICE which is significantly safer than TEE.
  • Understand heart anatomy and how to obtain correct device orientation
3 interactive cases
  • Normal fossa ovalis (including guidance)
  • Fibrotic fossa ovalis
  • Aneurysmal fossa ovalis


  • TSP course (the user needs to be subscribed to VIST® Live to have access to the e-course)

Precise puncture

Ability to puncture the fossa in
different points in preparation for
different procedures such as LAAO
or pulmonary vein isolation.


Visual Aids

Visual aids such as labeled anatomical structures shorten the learning curve.



Detailed metrics and benchmarking tools allow users to track progress to help optimize training and identify areas that need improvement.


Step-by-Step Guidance

Built in step-by-step expert guidance
encourages self-learning
without the need for proctoring.


ECHO views for ICE & TEE

Train as a team with an echocardiographer
or individually using preset echo views for ICE and TEE.


Built-in complications

Built-in complications show importance
of careful tool manipulation

“It is extremely difficult to obtain real hands-on training within the clinical setting, and to learn good hand-eye coordination and understand multi-modality imaging is key to the success or failure of your procedure. The level of reality in TEE and ICE imaging within the new Transseptal puncture and LAAO training solutions, and how it corresponds to what manipulation you do with the catheter is 99% close to reality. This is critical - and that is where Mentice has succeeded.”
