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.

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.  

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.

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.

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.

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.
