Background: There are few studies about the impact of diagonal branch blood flow on echocardiographic findings in patients with first acute anterior myocardial infarction undergoing primary angioplasty. Objectives: We aimed to compare left ventricular systolic function measures ST-segment elevation (STEMI) treated angioplasty based after procedure. Methods: This study was a single-center that e...

OBJECTIVES We sought to evaluate the effects of mechanical thrombectomy on myocardial reperfusion during direct angioplasty for acute myocardial infarction (AMI). BACKGROUND Embolization of thrombus and plaque debris may occur during direct angioplasty for AMI. This may lead to distal vessel or side branch occlusion and to obstructions in the microvascular system, resulting in impaired myocar...

Abnormal blood flow patterns promoting inflammation, cellular proliferation, and thrombosis may be established by local changes in vessel geometry after stent implantation in bifurcation lesions. Our objective was to quantify altered hemodynamics due to main vessel (MV) stenting and subsequent virtual side branch (SB) angioplasty in a coronary bifurcation by using computational fluid dynamics (...

background : during the last 3 decades, there were increasing tendency towards angioplasty because of its benefits. but, this procedure has its acute problems like bleeding and formation of hematoma in the removal place of the sheet. based on researchers’ clinical experiences, patients need a time of 8-12 hours for bed rest after coronary angioplasty. recognizing desirable time for bed rest aft...

A et al. Influence of time-to-treatment, TIMI-flow grades, and ST-segment resolution on infarct size and infarct transmurality as assessed by delayed enhancement magnetic resonance imaging. Detection of TIMI-3 flow before mechanical reperfusion with ultrasonic tissue characterization in patients with anterior wall acute myocardial infarction. Significance of a coronary artery with Thrombolysis ...

OBJECTIVES We compared outcomes following thrombolytic therapy and primary angioplasty with no reperfusion therapy in a population-based cohort of older patients presenting with acute myocardial infarction (AMI) and indications for acute reperfusion. BACKGROUND Evidence supporting the efficacy of acute reperfusion (thrombolytic therapy or primary angioplasty) in the elderly with suspected AMI...

Provisional side-branch stenting is currently the most widely accepted percutaneous technique for the treatment of bifurcation lesions. However, abrupt closure of the side branch may occur after main vessel stent implantation. Resolving side-branch stenosis under these conditions may pose major technical difficulties. We describe a new technique to resolve uncrossable side-branch occlusion foll...
