Background: Recent trials suggest that complete revascularization in patients with acute ST-segment-elevation myocardial infarction and multivessel disease is associated with better outcomes than infarct-related artery (IRA)-only revascularization. There are different methods to select non-IRA lesions for revascularization procedures. We assessed the clinical outcomes of complete angiographically guided revascularization versus stress echocardiography-guided revascularization in patients with ST-segment-elevation myocardial infarction.
Methods: We performed a randomized clinical trial in patients with multivessel disease who underwent a successful percutaneous coronary intervention of the IRA to test differences in prognosis (composite end point included cardiovascular mortality, nonfatal reinfarction, coronary revascularization, and readmission for heart failure after 12 months of follow-up) between complete angiographically guided revascularization (n=154) or stress echocardiography-guided revascularization (n=152) of the non-IRA lesions in an elective procedure before hospital discharge.
Results: The trial was prematurely stopped after the inclusion of 77% of the planned study population. As many as 152 (99%) patients in the complete revascularization group and 44 (29%) patients in the selective revascularization group required a percutaneous coronary intervention procedure of a non-IRA lesion before discharge. The primary end point occurred in 21 (14%) patients of the stress echocardiography-guided revascularization group and 22 (14%) patients of the complete angiographically guided revascularization group (hazard ratio, 0.95; 95% CI, 0.52-1.72; =0.85).
Conclusions: In patients with ST-segment-elevation myocardial infarction and multivessel disease, stress echocardiography-guided revascularization may not be significantly different to complete angiographically guided revascularization, thereby reducing the need for elective revascularization before hospital discharge.

Background And Purpose: The safety and effectiveness of endovascular techniques in elderly patients with large vessel occlusion (LVO) remain controversial. We investigated the angiographic and clinical outcomes of nonagenarians treated with different endovascular techniques using a balloon guide catheter (BGC), distal aspiration catheter (DAC), and/or stent retriever (SR).
Methods: We analyzed the data from the Registry of Combined versus Single Thrombectomy Techniques (ROSSETTI) of consecutive nonagenarian patients with anterior circulation LVO and compared the outcomes of those treated with BGC+noDAC+SR (101-group), BGC+DAC+SR (111-group), and noBGC+DAC+SR (011-group).
Optimal Strategy for Complete Revascularization in ST-Segment Elevation Myocardial Infarction and Multivessel Disease: A Network Meta-Analysis.

Background: In patients with ST-segment elevation myocardial infarction (STEMI) and multivessel coronary artery disease, most but not all randomized trials have reported that complete revascularization (CR) offers advantages over culprit vessel-only revascularization. In addition, the optimal timing and assessment methods for CR remain undetermined.
Objectives: The purpose of this study was to identify the optimal revascularization strategy in patients with STEMI and multivessel disease, using a network meta-analysis of randomized controlled trials.
Introduction: Renal artery pseudoaneurysm is a rare yet serious complication following percutaneous nephrolithotomy, especially in patients with solitary kidneys. Effective management is crucial to prevent further renal damage.
Case Presentation: We report a case of a 41-year-old male with a solitary kidney who experienced gross hematuria and renal insufficiency 3 months after percutaneous nephrolithotomy.

Introduction: In patients with chronic coronary syndromes (CCS), the benefit of percutaneous coronary intervention (PCI) added to optimal medical therapy (OMT) remains unclear. The indication to PCI may be driven either by angiographic evaluation or ischemia assessment, thus depicting different potential strategies which have not yet been thoroughly compared.
Methods: Randomized controlled trials (RCTs) comparing OMT versus PCI angio-guided or versus PCI non-invasive or invasive ischemia guided were identified and compared via network meta-analysis.

Objective: This study aimed to compare the efficacy and safety of intravascular ultrasound (IVUS)-guided coronary intravascular lithotripsy and rotational atherectomy in treating severe coronary artery calcification.
Methods: A retrospective analysis of 60 patients who underwent percutaneous coronary intervention at the General Hospital of Ningxia Medical University from October 2022 to August 2023 was conducted. The patients were divided into two groups: 30 received IVUS-guided coronary intravascular lithotripsy and 30 underwent IVUS-guided rotational atherectomy.
