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.

Late-breaking clinical trials at TCT 2023

Here is a list of all the late-breaking clinical trials being presented at the Transcatheter Cardiovascular Therapeutics (TCT) 2023 annual meeting Oct. 23-26, 2023, in San Francisco.

How monitoring MR can help cardiologists anticipate TAVR outcomes in patients with low-flow, low-gradient AS

Researchers uncovered new details about how mitral regurgitation can impact one-year TAVR outcomes, sharing their findings in the Journal of the American Heart Association.

Performing valve-in-valve transcatheter mitral valve replacement (ViV TMVR) with conscious sedation (CS) or monitored anesthesia care (MAC) instead of general anesthesia (GA) is safe and effective, according to new research published in JACC: Cardiovascular Interventions.

Cardiologists detail long-term outcomes of valve-in-valve TMVR

New research published in the Canadian Journal of Cardiology represents one the most detailed pictures to date of the long-term impact of ViV TMVR.

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.

“I was ready to make out my will, so this came along just at the right time,” the 76-year-old patient said.

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.

X-ray photon trajectory during the simulation phantom study from the side and top views. 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.
