Coronary Intervention & Surgery


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.

Women undergoing coronary angiography and, if indicated, PCI are more likely to experience severe bleeding and access-site complications than men, but intervening through the radial artery substantially reduced those events, according to data from the MATRIX trial.

Patients experiencing postoperative delirium (POD) after elective heart surgery shouldered more than triple the risk of experiencing a major adverse cardiac event (MACE) such as stroke, heart attack or cardiovascular death within a year of discharge, researchers reported in PLOS One.

Stent vs. Graft: Choosing the Best Path for the Diabetic Patient with Multivessel Disease

The prevailing notion is that bypass surgery is superior to stenting in patients with diabetes. The truth, however, is more complicated, as the decision-makers learn to examine the individual pathologies in lieu of standardization. Often, this process is more art than science in taking into account all of the parameters of a patients disease.

Interventionalists Get Pumped Up About Mechanical Chest Compression

If Europe is any indication of where mechanical cardiopulmonary resuscitation (CPR) is heading, interventional cardiologists in the U.S. should get ready to welcome the devices into their cath labs. European researchers have begun to validate the technique in arrested patients undergoing PCI.

Low-Volume Cath Labs without Surgical Backup are Here to Stay

Some research has demonstrated that performing elective percutaneous coronary interventions (PCI) in low-volume facilities, especially those without onsite cardiac surgery, can result in positive outcomes. Critics say, however, that these studies are mostly single-center investigations, which do not reflect the real risk of performing elective PCI without onsite surgical backup. In fact, critics point to studies using Medicare data, which do show an increase in mortality for patients treated at facilities without surgical backup.

Longer-Term Data, Better Patient Selection Lead to DES Comeback

Three recent clinical studies rebuke the previously held belief that drug-eluting stents (DES) led to higher rates of stent thrombosis (ST). As concerns over DES have begun to dissipate, their utilization is already increasing in the first half of 2008, and many experts think this trend will continue.

First Word: A Stent is a Stent is a Stent...or is It?

Drug-eluting stents (DES) would not be used if they did not benefit patients. To that end, vendors conduct clinical studies to show that their product is equal to or better than a previous-generation product or a current competitor’s product.

Planning for the Ideal Cath Lab Requires the Multidisciplinary Approach

Planning and creating the best cath lab for your facility and market requires a wide range of considerations, from current and future business patterns to space design to workflow and communication concerns. A good plan that includes input from all the relevant stakeholders goes a long way toward a successful long-term venture.
