Case report: ST-elevation myocardial infarction complications. How far will you go?

Herein, we review the critical role of a multi-disciplinary team approach in managing the intricate complications of ST-elevation myocardial infarction (STEMI) complicated by cardiogenic shock (CS). Mechanical circulatory support (MCS) implantation represents a potentially life-saving intervention, often serving as a bridge to heart transplantation (HTx). However, complications from prior interventions, in patients receiving MCS due to STEMI-CS, may present additional challenges to successful HTx candidacy.

Surgical coronary angioplasty of both coronary ostia after chest radiotherapy. Is it good alternative to conventional coronary bypass surgery?

Introduction: Isolated coronary ostial stenosis of both ostia is a rare, potentially life-threatening condition, occurring in 0.1%-0.2% of patients undergoing coronary angiography.

Left atrial strain rate: marker of hemodynamically significant coronary artery stenosis?

To assess the diagnostic value of left atrial deformation parameters during dobutamine stress echocardiography to predict significant coronary artery stenosis in patients with moderate pretest probability of coronary artery disease (CAD). Rest and stress echocardiography were performed on 61 patients with a moderate and high probability of CAD. Based on presence of CAD patients were divided into pathological and nonpathological groups.

Anterior basal left ventricular pseudoaneurysm in a single vessel disease.

Introduction: Left ventricular pseudoaneurysm is a rare but serious clinicopathologic entity.

Materials And Results: This article describes a case report of 51-year-old man who experienced recurrence of chest pain and dyspnea 4 months later after anterior ST elevation myocardial infarction of first diagonal branch. Anterior basal left ventricular pseudoaneurysm was diagnosed and successful surgical treatment was performed.

Value of myocardial deformation parameters for detecting significant coronary artery disease.

The study aimed to evaluate the diagnostic value of global and regional myocardial deformation parameters derived from two-dimensional speckle-tracking echocardiography to detect functionally significant coronary artery stenosis. Dobutamine stress echocardiography and cardiac magnetic resonance myocardial perfusion imaging (CMR-MPI) were performed on 145 patients with a moderate and high probability of coronary artery disease (CAD) and LVEF≥55%. Significant CAD was defined as>50% stenosis of the left main stem,>70% stenosis in a major coronary vessel, or in the presence of intermediate stenosis (50-69%) validated as hemodynamically significant by CMRMPI.

Intraoperative angiography during coronary artery bypass grafting.

Introduction: The aim of this study was to evaluate the incidence rate of technical failure of graft patency while performing intra-operative angiography after coronary artery bypass grafting.

Methods: This prospective pilot study included 50 patients with multi-vessel coronary artery disease who underwent coronary artery bypass grafting, in addition to intra-operative angiographic graft assessments, on open-chest. Overall, 144 grafts and 160 distal anastomoses were assessed in a hybrid operating room.

Correlation between Preoperative Coronary Artery Stenosis Severity Measured by Instantaneous Wave-Free Ratio and Intraoperative Transit Time Flow Measurement of Attached Grafts.

To assess the correlation between the degree of target coronary artery stenosis measured by instantaneous wave-free ratio (iFR) and the intraoperative transit time flow measurement (TTFM) of attached grafts as well as evaluate flow competition between the native coronary artery and the attached graft according to the severity of stenosis. In total, 89 grafts were subjected to intraoperative transit time flow measurement after coronary artery bypass grafting (CABG) in 25 patients with multivessel coronary artery disease (CAD). The iFR was evaluated for all coronary arteries with grafts.
