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.

TCT 2017: DK crush proves more effective than PS in first large-scale study of its kind

Though provisional stenting (PS) is the most popular PCI technique used to treat distal left main (LM) bifurcation lesions, a double kissing (DK) crush two-stent technique yielded more positive results in a large-scale randomized trial comparing the two, according to research presented at the 29th annual Transcatheter Cardiovascular Therapeutics (TCT) conference.

Heart patients with left main coronary artery disease (LMCAD) could benefit from more immediate results when receiving percutaneous coronary intervention (PCI) over coronary artery bypass graft surgery (CABG), according to research presented at this year’s Transcatheter Cardiovascular Therapeutics (TCT) symposium, though both procedures yield similar quality of life improvements after three years.

DENVER — Before the 29th annual Transcatheter Cardiovascular Therapeutics (TCT) scientific symposium kicked into full swing Oct. 30, a pair of doctors drew attention to two important anniversaries for interventional cardiology. The first PCI was performed 40 years ago and the first transcatheter aortic valve replacement (TAVR) was completed 15 years ago.
