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.

FDA approves Sentinel device from Claret to reduce stroke during TAVR

In a June 5 release, Claret Medical announced it had received regulatory clearance from the U.S. Food and Drug Administration for its Sentinel Cerebral Protection System. The device protects against stroke during transcatheter aortic valve replacement (TAVR) by capturing debris dislodged during the procedure.

Emerging surgical techniques shown to reduce heart surgery complications

A new study reports that emerging surgical techniques used to perform more extensive surgical repairs of type A dissection is improving long-term outcomes for patients.

The dawn of rejecting rejection?

Englishman John McCafferty holds the record as the world's longest surviving heart transplant patient. At the time of his surgery in the fall of 1982, physicians estimated he’d live five years. He lived another 30 on top of that—working, enjoying family, running half marathons, traveling, fundraising for a transplant support charity and trout fishing—before passing away just last summer.

The U.S. Food and Drug Administration (FDA) approved an expanded indication for the Sapien 3 Transcatheter Heart Valve, a move that will allow physicians to use the device to better treat patients with symptomatic heart disease.

SCAI 2017: TAVR outcomes depend on individual risk factors, not valve type

A late-breaking study, presented May 12 at the Society of Cardiovascular Angiography and Interventions meeting in New Orleans, showed that factors related to individual patients—and not the specific type of valve used—determined 30-day outcomes for transcatheter aortic valve replacement (TAVR).

SCAI 2017: Robotic PCI highly successful with transradial, transfemoral access

The May 12 late-breaking clinical trial at the Society for Cardiovascular Angiography and Interventions (SCAI) 2017 Scientific Sessions in New Orleans compared femoral and radial robotic percutaneous coronary intervention (PCI) procedures.
