The Center for Structural Heart Disease at the Henry Ford Hospital under the leadership of Dr. William O’Neill is one of the leading Structural Heart programs. Dr. Dee Dee Wang, Director of Structural Heart Imaging at the Henry Ford Hospital and Medical Director of 3D Printing at the Henry Ford Innovations Institute recently spoke at the Materialise World Summit that took place in Brussels earlier this year. During her talk, she shared why 3D technology plays a critical role in their work on Structural Heart procedures and mostly Transcatheter Mitral Valve Replacement (TMVR) therapy.
Hope for High-Risk Patients
Henry Ford Hospital’s Center for Structural Heart Disease in collaboration with the Henry Ford Innovation Institute uses 3D and 4D imaging to enhance patient safety and procedural outcomes for high-risk structural heart interventions.
Application of this novel technology allows Dr. O’Neill and his team to perform high-risk minimally invasive transcatheter valve replacement on a more precise level for patients who have otherwise been turned down for traditional open-heart surgery. The team gives their patients hope and strives for ultimate level of patient safety.
The critical role of 3D modeling
For Dr. Wang, the value of 3D technology is in the computer-aided design. She explains the two critical roles of 3D modeling in Transcatheter Mitral Valve interventions. One is to size the valve properly customized to each patient. The second is to make sure the depth and constraints of the valve fits in the patient’s heart without causing blockage of blood flow out the heart to the rest of the body (left ventricular outflow tract obstruction).
Transcatheter mitral valve replacement is one of the high-risk structural interventions being performed in the world, with a high-stakes risk of potential for harm, even death, to the patient without adequate 3D planning. If a newly implanted valve blocks the passage of blood from the Left ventricle to the Aorta, patients can suffer life-threatening complications. Identification of risk of LVOT obstruction prior to the procedure in itself can save a life and prevent a complication. This cannot be done accurately without 3D and 4D computer aided design software modeling.
In addition, 3D technology and 3D planning make it possible for the team to test device sizes, catheters and trajectories before approaching a case, says Dr. Wang. Providing all possible safety parameters gives the operators more confidence in handling high-risk cases.
"A life saved, and a death prevented."
During an interview with Materialise, Dr. Wang says that by using 3D modeling, they can provide customized care to individuals with patient-specific CAD modeling. Materialise Mimics enables them to pursue their passion in pioneering new methods while exercising the utmost patient safety.
Using Materialise Mimics Innovation Suite, Drs O’Neill, Wang and the Henry Ford Innovative Institute are able to simulate implanted valves before procedures and identify the most optimal position for valve deployment. The impact, she says, is a patient's life is saved.
Materialise MIS for TMVR
There are many ways Materialise MIS can be used to inspire innovative medical developments. The Henry Ford Structural Heart Disease team and Innovative Institute is using Materialise MIS to indicate the high quality 3D patient planning for mitral procedures and develop a workflow and tool for physicians to use worldwide.
