Interventional Cardiology

This cardiac subspecialty uses minimally invasive, catheter-based technologies in a cath lab to diagnose and treat coronary artery disease (CAD). The main focus in on percutaneous coronary interventions (PCI) to revascularize patients with CAD that is causing blockages resulting in ischemia or myocardial infarction. PCI mainly consists of angioplasty and implanting stents. Interventional cardiology has greatly expanded in scope over recent years to include a number of transcatheter structural heart interventions.

Feature: Changing cath lab shortcomings into long-term gains

An analysis of catheterization reports from the first 10 facilities to undergo review by the Accreditation for Cardiovascular Excellence (ACE) found that many fell short for documenting patient risk and appropriateness of PCI. Rectifying shortcomings is achievable, according to one hospital that went through the accreditation process, and the changes can lay the groundwork for other improvements.

Making PCI safe for operators

The growth in fluoroscopy-guided procedures has put operators between a rock and a hard place, or should I say, between exposure to radiation and the opportunity to obtain clinically useful information. According to the American Heart Association, the rate of patients who underwent PCI increased 58 percent between 1992 and 2004, making the potential for cumulative exposure to operators as they treat more of these patients greater.

SCAI: Iliac stents gain MOBILITY in treatment of PAD

LAS VEGASWhen treating a real-world sample of patients for intermittent claudication or critical limb ischemia, two off-label iliac artery stents showed a statistically significant performance goal for low major adverse event rates, according to the late breaking MOBILITY trial results presented May 10 at the 35th annual meeting of the Society for Cardiovascular Angiography and Interventions (SCAI). During the press conference, experts suggested that this study may further reinforce the role of percutaneous treatments over the more invasive surgical option for these sick patients.

SCAI: Robotic-assisted PCI is safe for patients, safer for operators

LAS VEGASA robotic remote-control coronary intervention system demonstrated technical and clinical effectiveness comparable to manual operation, but the operator exposure to radiation was significantly lower, based on PRECISE, a late breaking clinical trial presented May 10 at the 35th annual meeting of the Society for Cardiovascular Angiography and Interventions (SCAI).

SCAI: Where and how angio falls short in the cath lab

LAS VEGASCoronary angiography has a variety of limitations in the cardiac cath lab due to both operator and technological causes, according to a May 9 presentation by J. Dawn Abbott, MD, of Rhode Island Hospital in Providence, at the 35th annual meeting of the Society for Cardiovascular Angiography and Interventions (SCAI).

SCAI: Best bailout strategy for radial failures? Switch sides

LAS VEGASWhile higher failure rates with transradial PCI are clearly aligned with lower operator volumes, Christopher T. Pyne, MD, of the Lahey Clinic in Burlington, Mass., suggested that switching sides of the transradial is a better bailout strategy than going femoral, during a May 9 presentation at the 35th annual meeting of the Society for Cardiovascular Angiography and Interventions (SCAI).

AIM: False STEMI activations lead to costs, inappropriate cath lab use

While STEMI patients benefit from reperfusion therapy with PCI, a two-center study published May 7 in the Archives of Internal Medicine found than one-third of patients referred for primary PCI from the emergency department did not have a STEMI and 36 percent were deemed to be false-positive activations. An accompanying editorial questioned the impact of these false-positive activations and concluded that they lead to high costs and increased risk.

AATS: Study questions insulin protocols for CABG patients

Cardiothoracic surgeons and endocrinologists from Boston Medical Center have found that among patients undergoing CABG surgery, achieving Surgical Care Improvement Project benchmarks for glycemic control may be irrelevant when perioperative continuous insulin infusion protocols are implemented. These findings were presented May 1 at the annual meeting of the American Association for Thoracic Surgery (AATS) in San Francisco.

Around the web

Several key trends were evident at the Radiological Society of North America 2024 meeting, including new CT and MR technology and evolving adoption of artificial intelligence.

Ron Blankstein, MD, professor of radiology, Harvard Medical School, explains the use of artificial intelligence to detect heart disease in non-cardiac CT exams.
