Coronary Intervention & Surgery


A cross-sectional study of nearly 1,300 patients revealed Chinese physicians systematically overestimate the severity of coronary stenosis, perhaps even more so than in the United States, likely leading to many patients being inappropriately treated with percutaneous coronary intervention (PCI).

The risk of another heart attack following percutaneous coronary intervention (PCI) was twice as likely to originate from a previously untreated lesion versus the stented lesion, according to a study of a large Swedish cohort published in the Journal of the American Heart Association.

Patients are significantly more likely to die within one year of coronary artery bypass graft (CABG) surgery or PCI in New York state than in England where the procedures are roughly four times cheaper, according to a study in Open Heart.

Temporarily cooling part of the heart during myocardial infarction (MI) and again immediately after angioplasty may reduce damage to the heart, said a cardiologist who participated in the first in-human study of the technique.

Charles E. Chambers, MD, spoke with Cardiovascular Business about the risks of radiation exposure to interventional cardiologists and potential solutions.

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.
