Coronary Intervention & Surgery

 - Glass Half Full

Lowering the amount of contrast used and encouraging more oral hydration before and after a PCI procedure reduced contrast-induced acute kidney injury by 21 percent, according to a study published online July 29 in Circulation: Cardiovascular Quality and Outcomes


Initiatives to provide timely treatment for patients with acute MI overall appear to making an impact but hospitals still have room to improve in their care of patients who present off-hours, an analysis published online July 29 in Circulation: Cardiovascular Quality and Outcomes suggests.

 - heart, cardiology, cardiac

Physicians in the U.S. who treat patients with multivessel coronary disease rarely turn to a hybrid approach for therapy. Over a two-year period, only 0.48 percent of CABG procedures included hybrid coronary revascularization (HCR), reported a study published online July 23 in Circulation.

 - medicine money

Findings published July 5 in Lancet show low-dose heparin alone to be at least as effective and safe as bivalirudin alone when used in radial PCI in acute MI patients presenting with STEMI, if not more so.

 - clinical trial

Resolute zotarolimus-eluting stents were found to be as safe and effective after two years in small vessels and in patients with diabetes as those with larger diameters or patients without diabetes. In diabetic patients, outcomes were not significantly different between larger and smaller vessel diameters.

Left radial PCI reduces operators’ radiation exposure by half

Radiation exposure to the operator was nearly half when performing PCI by a left radial approach rather than right, according to a study published online June 18 in the Journal of the American College of Cardiology: Cardiovascular Interventions

Angiography as good as FFR & IVUS for post-PCI long-term survival

While fractional flow reserve (FFR) and intravascular ultrasound (IVUS) may reduce the need for repeat revascularization, they apparently don’t make a dent in long-term mortality compared with angiography-guided PCI. But FFR may help reduce stent use, according to results published online June 23 in JAMA Internal Medicine.

Preoperative beta-blocker use may not help with CABG

The latest study to examine the preoperative use of beta-blockers in CABG found no mortality benefit combined with an uptick in postoperative atrial fibrillation. Still, it probably is not time to take an eraser to related quality metrics or guidelines. 

A break for CABG? Readmissions measure uses clinical data

With penalties for higher-than-expected 30-day readmissions for CABG on the horizon, concerns about how hospitals will be measured have been growing. A method that linked clinical data to administrative data may provide an answer.

Increasing radial PCI use even slightly may lower bleeding rates

Hospitals that readily embraced transradial PCI over a three-year period were more likely to see reduced bleeding rates, an analysis of CathPCI data showed. But even facilities that had modest increases in radial PCI use achieved lower access site and overall bleeding rates.

Off-pump CABG shows short- but not long-term kidney benefits

Patients who underwent off-pump CABG surgery were less likely than on-pump patients to experience postoperative acute kidney injury, based on an analysis of CORONARY data published in the June 4 issue of JAMA. But kidney function remained similar between the groups at one year.

Hospital pays $41M to settle overstenting case

A hospital in Kentucky agreed to pay almost $41 million to put a case alleging unnecessary cardiac stenting and diagnostic catheterizations behind it.

1 in 3 patients don’t fill clopidogrel script soon after PCI

One third of patients who were discharged after a PCI failed to fill their clopidogrel prescriptions within three days, according to a study published online May 28 in Journal of the American Heart Association, at the risk of serious consequences. Findings showed that the time following hospital release to the filling of the prescription dramatically influences outcomes.

An exclusive club? Non-system delays may bolster reported D2B times

An assessment of hospitals that perform primary PCI found a four-fold difference between facilities that frequently and rarely exclude patients based on non-system delays in reports on door-to-balloon (D2B) times. The variation affected compliance to the D2B metric.

Protocol slashes radiation dose but not cath lab volume

Operators reduced radiation dose 48 percent with no loss in volumes or interventions using a novel algorithm in the catheterization laboratory, researchers reported online April 16 in the Journal of the American College of Cardiology: Cardiovascular Interventions.

Radial PCI learning curve ranges from 30 to 50 cases in U.S.

The learning curve for transradial PCI in the U.S. is “relatively shallow” and similar to that for operators outside the U.S., according to an analysis of CathPCI Registry data that was published online April 22 in Circulation.

Drug-eluting stents match bare metal stents in NEXT

Drug-eluting stents may be as safe a choice as bare metal stents when followed by a blood thinning regimen tailored to individual patients, based on the results of a research letter published March 31 in the JAMA.

Societies offer go-to resource for PCI centers without surgical backup

PCI centers that don’t provide on-site surgical backup caught a break on March 17 with the publication of a paper that consolidates recommendations into a single document. “We tried to take everything that has been out there and put it all in one resource so people don’t have to hunt around,” lead author Gregory J. Dehmer, MD, told Cardiovascular Business.

Gender gap extends to treatment for acute coronary syndrome

Younger women with acute coronary syndrome may not receive care as quickly as men, a study published online March 17 in the e Canadian Medical Association Journal found. The study also found that women were less likely than men to get certain treatments for ST-segment elevation myocardial infarction (STEMI), non-ST-segment elevation MI (NSTEMI) or unstable angina.


Reasons behind variation in NSTEMI bleeding rates unclear

The rate of in-hospital major bleeding events among non-ST-segment elevation myocardial infarction (NSTEMI) patients varies considerably between facilities, researchers found in a study published online March 4 in Circulation: Cardiovascular Quality and Outcomes, but the reasons behind the majority of cases remain unclear.

Transradial PCI may lower risk of acute kidney injury

To prevent acute kidney injury (AKI) in patients undergoing PCI, physicians may want to select a transradial approach rather than a transfemoral approach. A study published online Feb. 25 in Circulation: Cardiovascular Interventions found an association between radial PCI and a lower risk of AKI compared with the femoral approach.
