Cath Lab

The cardiac catheterization laboratory is used for diagnostic angiograms and percutaneous coronary interventions (PCI). Cath labs have also seen expanding use in recent years for transcatheter structural heart procedures. Some hospitals also share these labs with other subspecialties for catheter-based procedures in electrophysiology (EP), interventional radiology, peripheral artery disease (PAD), carotid and neuro interventional procedures and vascular surgery.

Socioeconomic status and mental health make a big impact on AVR outcomes

Nontraditional risk factors such as dementia, PTSD, bipolar disorder and low socioeconomic status are all important to consider when patients are candidates for aortic valve replacement.

Radial artery grafts vs. saphenous vein grafts for CABG: Does one outperform the other?

The new study, published in Circulation, represents a collaboration between specialists from a variety of facilities, including Cleveland Clinic and the University of Arizona. 

Example of fractional flow reserve (FFR) calculated using AI and assessment of the plaque in the vessel on a CT scan of the coronaries. This new type of FFR-CT was shown as a work-in-progress by the vendor Elucid. It was shown for the first time at AHA 2022.

Interview with the late-breaking BEST-CLI trial principal investigators Alik Farber from Boston Medical Center, Matthew Menard from Brigham and Women's Hospital, and Ken Rosenfield at Mass General Hospital, at the 2022 American Heart Association (AHA) meeting. The trial looked at endovascular versus bypass surgery in patients with critical limb ischemia (CLI) to see which is better. #AHA22

Emergency hospital transfer of STEMI patients might be expedited with a hospital-level 'Call 911 protocol'

The AHA Mission: Lifeline Program was designed to reduce STEMI patient transfer times, but response times still often lag, and new protocols may be needed to expedite STAT transfers.

The Medtronic Symplicity Spyral Renal Denervation system uses a catheter that curls in the renal artery to place radiofrequency electrodes against the vessel wall to ablate the nerves that control vasodilation, so the artery can be propped in the fully open position.

SPYRAL HTN-ON MED renal denervation study did not meet primary endpoint

The SPYRAL HTN-ON MED renal denervation trial failed to show that renal denervation was superior to sham control at improving ambulatory blood pressure (ABPM), but that might have been due to patient lifestyle changes during COVID-19.

Predictors of 1-year mortality after TAVR are significantly different among men and women

Atrial fibrillation and peripheral artery disease, for example, are both predictors of mortality among women, but not men.
