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.

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.
