Coronary Intervention & Surgery


Hospitals ranked in the top 50 for cardiology and heart surgery by U.S. News and World Report appear no better at performing PCI than unranked hospitals, according to an analysis of more than 500,000 procedures performed at 654 hospitals.

PCI of chronic total occlusions (CTOs) can be safely performed by expert operators and provides significant benefit to patients with reduced left ventricular ejection fraction (LVEF) or diabetes, according to a series of studies published Nov. 13 in JACC: Cardiovascular Interventions.

Scaffold discontinuity, malapposition and neoatherosclerosis were found to be the leading mechanisms behind very late scaffold thrombosis (VLScT) in cardiac patients implanted with bioresorbable devices, investigators from the INVEST registry have reported.

Recent studies have shown robotic PCI to be a feasible way to treat coronary artery disease. But at the annual Transcatheter Cardiovascular Therapeutics (TCT) conference Oct. 30, Ryan D. Madder, MD, took the conversation a step further: Will it eventually be possible to perform “tele-stenting” over long distances?

Research presented Nov. 2 at the Transcatheter Cardiovascular Therapeutics scientific symposium in Denver demonstrates patients with stable coronary artery disease (CAD) and abnormal fractional flow reserve (FFR) derive better clinical outcomes with PCI at similar cost to medical therapy alone.

Medtronic’s TAVR platform approved for expanded use by FDA

Want to predict mortality in elderly TAVR, SAVR patients? Use this four-item scale

It’s logical that frailty factors into recovery from major heart surgery. But what, exactly, is the best method for judging a patient’s frailty before transcatheter or surgical aortic valve replacement (TAVR/SAVR)? A study published online July 7 in the Journal of the American College of Cardiology explored this question by examining seven frailty scales in predicting poor outcomes.

New manufacturing methods can further personalize medicine—and now 3D printing may offer cardiologists a method of testing transcatheter aortic valve replacements (TAVR) for leakage before implantation.
