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 announces longer-term clinical study of TAVR system

Medtronic has announced a new study to evaluate its next-generation transcatheter aortic valve replacement (TAVR) system in everyday clinical practice. The self-expanding CoreValve Evolut PRO valve was recently approved for commercial use in Europe and the United States.

Cerebral embolic protection device cuts risk of TAVR procedures

Adding a cerebral embolic protection (CEP) device to standard transcatheter aortic valve replacement (TAVR) was associated with a threefold reduction of all-cause mortality or stroke within one week of the procedure, according to a new study in JACC: Cardiovascular Interventions.

CABG, PCI show similar long-term outcomes

Coronary artery bypass grafting (CABG) and PCI demonstrated similar long-term outcomes in treating left main coronary artery stenosis, according to a systematic review and meta-analysis of 4,394 patients. However, PCI was associated with a 70 percent increased risk of repeat revascularization.

Intracardiac echocardiography for guidance of LAAO reduces time in cath lab

A recent study compared intracardiac echocardiography (ICE) and transesophageal echocardiography (TEE) for procedural guidance of left atrial appendage occlusions. Both approaches proved to be safe and effective, with no increase in procedure-related complications arising with ICE.

Bioresorbable vascular scaffolds similar to drug-eluting balloons, inferior to everolimus-eluting stent for restenosis

Bioresorbable vascular scaffolds (BVS) appear to offer a safe, innovative therapy for those difficult-to-treat patients who experience in-stent restenosis (ISR), according to a new multicenter study conducted in Europe.

Maquet recalls intra-aortic balloon pumps

Maquet has issued a Class I recall on more than 5,000 intra-aortic balloon pumps (IABPs) in the United States due to a false blood detection alarm and the entrance of fluid into the devices. The IABPs are cardiac assist devices used for patients with acute coronary syndrome or complications from heart failure.

Systems approach shows promise for out-of-hospital CAD

Survival with favorable quality of life improved among patients with refractory out-of-hospital ventricular fibrillation (VF)/ventricular tachycardia (VT) cardiac arrest when they were quickly taken to a cardiac catheterization laboratory (CCL) for extracorporeal life support (ECLS) and revascularization, as opposed to being treated with prolonged resuscitation efforts at the scene of their heart attack, according to new research.

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.
