Valve Research Group

Affiliated with



The VRGG team collaborates extensively wit the Valve Research Group of prof. Mahmood (Harvard) and with the Gorman Cardiovascular Research Group (uPenn). This collaboration exists of data sharing, research fellowships and collaborations in larger research projects. We have certain points of interest, although we are continiously searching for interesting research topics regarding cardiac valves. Our main research topics are:
3D Trans-esophageal echocardiography (TEE)
Withe the data generated from 3d TEE, we are able to analyse many parameters regarding cardiac function. Our highly specialised software (TomTec) allowes us to do so. 
Mitral Valve Analysis


The VRGG is a versatile group and provides not only a healthy research envoirnment for students, but has also many educational goals. We run multiple annual training programs for residents, scrub nurses, medschool students and fellow physicians. Here are some of our programs:

  • Surgical cardiac anatomy course (4x per year)​​

       In this fun, hands-on training by our proffesional surgical staff, students are educated in the detailed                cardiac anatomy using porcine hearts. 

  • High fidelity cardiac surgical training for residents in our state of the art training OR 

       ​Our training facility contains all the equipement that a normal OR has to offer. With our specially                      developed technique to perform beating heart surgery on preserved human cadavers, we are able to                mimick a real OR setting for training purposes. 

  • Trans-esophageal echocardiography (TEE) training

       Our team provides annual TEE  ​training for residents or whoever is interested. This hands-on training                is provided using a unique TEE simulator for best possible results.
