Multidisciplinary Series: Advancing Heart Care with 3DQ Imaging for TMVR
January 29, 2025
A patient with severe mitral regurgitation underwent a transcatheter mitral valve replacement (TMVR) led by cardiothoracic surgeon John W. MacArthur, MD, and interventional cardiologist Rahul P. Sharma, MD, at Stanford Health Care. The minimally invasive procedure replaced a calcified mitral valve using a catheter-based approach. Dr. MacArthur is an Assistant Professor in the Stanford Department of Cardiothoracic Surgery, and Dr. Sharma is a Clinical Associate Professor of Cardiovascular Medicine and Director of Structural Interventions at Stanford Health Care.
Prior to the procedure, the patient was referred to the Stanford 3D and Quantitative Imaging (3DQ) Laboratory for advanced medical imaging, which was featured in a case study series. Through a multidisciplinary approach, the lab works in close collaboration with other departments, including cardiothoracic surgery, cardiovascular medicine, and radiology.

The cross-departmental collaboration with the Stanford Department of Radiology includes Brian Pogatchnik, MD, Clinical Assistant Professor, who oversees TMVR workflows, and Dominik Fleischmann, MD, Professor and Medical Director of the 3DQ Lab, who leads the lab’s efforts with the cardiac surgery and interventional cardiology valve teams. Together, they refine and optimize these workflows.
All 3DQ Lab work is performed under the supervision and guidance of radiologists, who play a critical role in ensuring the highest quality imaging support for interventional procedures. Their expertise helps translate imaging data into actionable insights, aligning with the needs of clinicians, interventionalists, and surgeons.
This collaboration across departments and specialties, including cardiothoracic surgery, cardiovascular medicine, interventional cardiology, radiology, and cardiovascular imaging, ensures a comprehensive approach to advancing patient care through innovation and expertise.
