Safety and Efficacy of Polyvinyl Alcohol Granules in Treating Type II and III Coronary Artery Perforation.

Objective: The success rate of polyvinyl alcohol (PAV) granules in the treatment of coronary artery perforation (CAP) was investigated to determine their safety and efficacy.

Methods: Forty patients with II and III coronary artery perforations during percutaneous coronary intervention were divided into two groups. One group was only occluded by low pressure balloons (balloon occlusion group), and the other one was occluded with PVA granules during low-pressure balloon dilatation (PVA granules embolization group).

Intracoronary microcatheter indwelling for continuous pumping of low-dose thrombolytic drugs: A new approach to reperfusion in acute myocardial infarction.

Reperfusion therapy of acute myocardial infarction (AMI) refers to physical or chemical recanalization and restoration of blood flow to an occluded coronary artery, and current techniques for reperfusion therapy include intravenous thrombolysis, percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG). The number of patients receiving emergency CABG in the real world is decreasing due to the disadvantages of CABG and the improvement in PCI procedures. Thrombolytic therapy has some disadvantages such as low recanalization rate, high risk of reocclusion and bleeding, and short time window.

Low-Shear Stress Promotes Atherosclerosis via Inducing Endothelial Cell Pyroptosis Mediated by IKKε/STAT1/NLRP3 Pathway.

Atherosclerosis is initiated by vascular endothelial dysfunction, and low-shear stress (LSS) of blood flow is a key factor leading to endothelial dysfunction. Growing evidence suggests that endothelial cell pyroptosis plays an important role in the development of atherosclerosis. Studies have shown that low-shear stress can induce endothelial cell pyroptosis, but the exact mechanism remains unclear.

Efficacy of one- vs. two-stent implantation for coronary bifurcation lesions in diabetic patients utilizing AIR2 as an endpoint.

Objective: This study aimed to assess the long term outcomes (all-cause death, myocardial infarction, target vessel revascularization, and silent restenosis at 12 months) of one-stent vs. two-stent implantation due to coronary bifurcation lesionsin diabetic patients using AIR2 as a new endpoint.

Methods And Results: A total of 178 diabetic patients with true coronary bifurcation lesions underwent percutaneous coronary intervention in the DK-Crush trials.

Acute renal injury after thoracic endovascular aortic repair of Stanford type B aortic dissection: incidence, risk factors, and prognosis.

Background/purpose: Acute kidney injury (AKI) significantly increases the risk of mortality in patients following cardiovascular intervention procedures. This study was carried out to investigate the incidence, predictors, and prognostic implications of AKI after thoracic endovascular aortic repair (TEVAR) of Stanford type B aortic dissection.

Methods: A total of 156 patients with Stanford type B aortic dissection who underwent TEVAR were retrospectively analyzed between February 1, 2004 and October 31, 2011.
