Interventional cardiology news to note
A retrograde approach adopted for chronic total occlusion procedures in 2007 at a high-volume center in Korea was associated with increased technical success but no better in-hospital outcomes than with the antegrade-only approach. It was even associated with more target vessel failure in the long-term. (EuroIntervention)
Treating de novo lesions using only drug-coated balloons (with the possibility of provisional stenting) was found to be safe in a registry study reported in Catheterization and Cardiovascular Interventions. The authors suggested this strategy for patients with high bleeding risk, as dual antiplatelet therapy typically lasted 1 month.
, assessed with a point-of-care global thrombosis test, predicted major adverse cardiovascular events after percutaneous coronary intervention (PCI) for ST-segment elevation MI (STEMI), a group reported in European Heart Journal
Another predictor of worse outcomes after PCI for STEMI is the formation of left ventricular thrombus, suggesting warfarin could be helpful, a Chinese center found. (Clinical Cardiology)
Factors predicting a good outcome after mechanical thrombectomy for large vessel occlusion strokes in the anterior circulation did not include treatment within 6 hours of symptom onset, according to a German registry. A simpler way to select patients for thrombectomy in longer and unknown time windows could be just the Alberta Stroke Programme Early CT Score and clinical criteria, the researchers suggested.

Doubling the dose of standard heparin reduced the risk of radial artery occlusions after transradial coronary angiography in the SPIRIT OF ARTEMIS trial. "High intensity anticoagulation should be considered in transradial diagnostic procedures," the investigators concluded in JACC: Cardiovascular Interventions.
Whereas PCI didn't stave off mortality for patients with stable heart disease in the COURAGE trial, better lifestyle and risk factor control were associated with increased odds of survival. Only 3% of trial participants had achieved control of six key risk factors by 1 year. (Journal of the American College of Cardiology)
