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.

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.

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.

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.

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.

Open repair of chronic thoracic, thoracoabdominal aortic dissection with deep hypothermia ups 10-year survival

Open repair of chronic thoracic and thoracoabdominal aortic dissection using hypothermia offers many advantages in suitable patients with this complex pathology and continues to represent the gold standard, according to new research. 

Study clarifies prognostic markers for STEMI patients undergoing PCI

With a goal of early risk stratification, a team of Korean researchers studied the impacts of serum biomarkers in ST-elevation myocardial infarction (STEMI) patients undergoing primary PCI. They published their findings online in PLOS One.

Trial to evaluate shorter course of blood-thinning treatment following stent implantation

Abbott has begun to compare three months of dual antiplatelet therapy (DAPT) to the current standard of 12 months after everolimus-eluting coronary stent implantation.

Safety-net hospitals compete in PCI mortality, bleeding, kidney injury

Although safety-net hospitals (SNHs) provide care for greater proportions of uninsured patients, in-hospital mortality rates related to percutaneous coronary interventions (PCIs) are only slightly higher than at other hospitals.

FDA clears acoustic, ECG device from AUM Cardiovascular to detect heart murmurs

AUM Cardiovascular has received clearance from the U.S. Food and Drug Administration (FDA) for its acoustic and ECG device to detect heart murmurs.

Blood vessel regeneration could help reverse MI tissue damage

A new study done by researchers in the United Kingdom explores how manipulating the hormone leptin to grow new blood vessels could help regenerate tissues in heart failure patients.
