Mitral Valve

The heart's mitral valve is the site of the most surgical valve repairs and valve replacements. After the resounding success of transcatheter aortic valve replacement (TAVR), which now makes up more than 50% of aortic valve replacements, there is wide expectation transcatheter mitral replacements will follow in the next few year. Currently, the most common transcatheter mitral procedure is transcatheter edge-to-edge (TEER) , using the MitraClip or Pascal clip devices. These devices are also being used for transcatheter tricuspid valve repair (TTVR). Other transcatheter mitral repair systems are in trials for minimally invasive annuloplasty and chordae tendineae repair.

Interventional echocardiographers play a key role in the treatment of structural heart disease

Rebecca Hahn, MD, examines the growing role of the dedicated interventional echocardiographer and how these imagers are paid.

Mitral valve repair: How a minimally invasive approach compares to conventional surgery

Researchers compared minithoracotomy, a minimally invasive procedure for treating degenerative mitral regurgitation, with conventional surgery, sharing their findings in JAMA. The research was previously presented as a late-breaking study at ACC.23.

TVT 2023: Cardiovascular Research Foundation announces late-breaking clinical trials

In addition to these 15 late-breaking clinical studies, TVT 2023 will feature live cases, hands-on training, poster presentations and much more.

Due to scattering of the X-rays when they hit the lower end of the patient bed, exposure in mainly to the lower body of the interventional echocardiographer performing transesophageal echocardiography. The green lines are the scattered photon trajectories calculated by Monte Carlo simulation in the study.

Radiation exposure in the cath lab: Tracking the impact on interventional echocardiographers

Researchers found that echocardiographers in the cath lab are exposed to high doses of radiation on the right half of their body, especially the waist and lower body. 

Raj Makkar, MD, Cedars-Sinai’s vice president of Cardiovascular Innovation and Intervention and the Stephen R. Corday, MD, Chair in Interventional Cardiology, explains the ACC 2023 results on the safety and efficacy of transcatheter edge-to-edge mitral valve repair in degenerative mitral regurgitation (MR) study. It was a review of data is from the STS/ACC TVT Registry that was presented at the American College of Cardiology (ACC) 2023 meeting.

An updated look at surgically repairing the mitral valve due to mitral regurgitation

A team of cardiologists and cardiac surgeons collaborated on the new analysis, reviewing data from more than 50,000 patients and developing a new risk model for clinicians.
