Interventional Cardiology

This cardiac subspecialty uses minimally invasive, catheter-based technologies in a cath lab to diagnose and treat coronary artery disease (CAD). The main focus in on percutaneous coronary interventions (PCI) to revascularize patients with CAD that is causing blockages resulting in ischemia or myocardial infarction. PCI mainly consists of angioplasty and implanting stents. Interventional cardiology has greatly expanded in scope over recent years to include a number of transcatheter structural heart interventions.

SCAI.16: Patients undergoing TAVR have superior outcomes with moderate anesthesia

Patients who received moderate anesthesia while undergoing percutaneous transcatheter aortic valve replacement (TAVR) had a shorter length of stay in the hospital and lower 30-day mortality compared with patients who received general anesthesia, according to an observational registry analysis.

SCAI.16: Patients receiving the Avert system have reductions in contrast media volume

Patients at risk for contrast-induced acute kidney injury while undergoing coronary angiography had a 15.5 percent relative reduction in contrast media volume when using the Avert system (Osprey Medical), according to a prospective, multicenter, randomized trial. 

SCAI.16: Quality improvement project helps decrease bleeding and costs following PCIs

A quality improvement project led to a 40 percent, risk-adjusted decrease in bleeding rates following PCIs during a 21-month period. The initiative also decreased costs by approximately $1 million.

SCAI.16: Robotic-assisted PCIs have similar outcomes to manual PCIs

A prospective analysis found that patients with significant comorbidities and complex coronary artery anatomy have similar outcomes if they undergo robotically assisted or manual PCI.

Carotid artery stenting and carotid endarterectomy lead to similar outcomes in Medicare patients

After adjusting for patient- and provider-level factors, Medicare patients had similar rates of death, stroke/transient ischemic attack, periporocedural MI and a composite of those outcomes if they underwent carotid artery stenting or carotid endarterectomy, according to a retrospective cohort study.

Video compares TAVR and surgery for intermediate-risk patients

A short video from the New England Journal of Medicine provides an overview of a study comparing transcatheter and surgical aortic valve replacement in intermediate-risk patients. 

Subgroup analysis shows IN.PACT Admiral drug-coated balloon is effective in females and diabetics

Medtronic released results of a few studies involving its IN.PACT Admiral drug-coated balloon in patients with peripheral artery disease.

Bleeding rates following PCI vary depending on hospital, patient factors

A registry analysis of PCI procedures found patient factors accounted for 20 percent of the overall hospital-level variation in bleeding.
