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.

New research suggests change atop DES hierarchy

Orsiro drug-eluting stents (DES) outperformed the current standard device for percutaneous coronary intervention (PCI) in a randomized international trial, according to a presentation from the European Society of Cardiology Congress.

CABG outperforms PCI in patients with type 1 diabetes

Coronary artery bypass grafting (CABG) demonstrates favorable results when compared to PCI in patients with type 1 diabetes (T1D), according to a new study in the Journal of the American College of Cardiology.

Self-expanding stents outperform balloon-expandable stents for iliac artery disease

Self-expanding (SE) stents proved more effective than balloon-expandable (BE) stents for the treatment of atherosclerosis of the iliac arteries and are thus recommended for affected patients, according to researchers who recently compared the two versions among a large group of patients being treated in northern Europe.  

Case study examines percutaneous management of mitral perforation TAVR

During transcathether aortic valve replacement (TAVR) procedures, the mitral apparatus may suffer serious, potentially lethal impairment, according to a new case study describes an approach to address the problem through percutaneous management.

High platelet reactivity to clopidogrel associated with greater risk of stent thrombosis, MI

Patients demonstrating high platelet reactivity (HPR) on clopidogrel are more likely to suffer stent thrombosis (ST) or MI within two years of stent implantation, according to a new study in JACC: Cardiovascular Interventions.

Construction worker who shoots nail into his heart: ‘Oops’

A Peshtigo, Wisconsin, resident was working on a fireplace when he dropped his nail gun. It then fired a 3.5-inch framing nail directly into his torso—missing his aorta by a millimeter.

Parachute device improves hemodynamic effects of LV volume reduction

A small study showed that the Parachute device increased the synchronicity of contraction, with observed leftward shifts of the pressure-volume (PV) loop and end-systolic pressure volume relationship (ESPVR), when used in a group of patients with aneurismal apices secondary to myocardial infarction.

Pulmonary artery catheter use drops 70% between 1999-2013

Use of pulmonary artery catheters (PACs) decreased by nearly 70 percent from 1999 to 2013 despite improving clinical outcomes, according to a cohort study of Medicare beneficiaries.
