In the last twenty years, the treatment of coronary heart disease with cardiac catheterization has greatly advanced. This therapeutic approach has had unexpected side effects, however, for which solutions must be found, particularly in the are of interventional cardiology. The “noreflow” phenomenon, a side effect, is an uncommon and critical occurrence and, if not reversed, causes a high rate o...
OBJECTIVE The coronary slow flow phenomenon (CSFP), which is characterized by delayed distal vessel opacification in the absence of significant epicardial coronary disease, is an angiographic finding. The aim of this study is to investigate the association between platelet-to-lymphocyte ratio (PLR) and coronary blood flow rate. METHODS This is a retrospective observational study. It was based...
Flow mediated brachial dilatation (FMD) and carotid intima-media thickness (IMT) have been a surrogate for early atherosclerosis. Slow coronary flow in a normal coronary angiogram is not a rare condition, but its pathogenesis remains unclear. A total of 85 patients with angina were evaluated of their brachial artery FMD, carotid IMT and conventional coronary angiography. Coronary flow was quant...
Background: Slow coronary flow (SCF) is defined as a condition in which in spite of no evidence of coronary occlusion or stenosis in angiography, there is delayed pacification of the vessels after the injection of a contrast agent. There are several studies about electrocardiogram (ECG) changes in these patients, but changes like OLD MI, RBBB, LBBB, LVH and ST-T wave have not b...
A case of primary percutaneous coronary intervention (PCI) is shown in the elderly patients with an ST-segment myocardial infarction. Stent deployment following the extensive thrombus aspiration resulted in a slow-flow phenomenon. Optical coherence tomography imaging showed a huge thin-capped fibro-atheroma encroaching the landing zone for stent placement. The author discusses possible factors ...
Coronary air embolism is a rare event. We report a case in which an acute myocardial infarction occurred in the region supplied by the right coronary artery after the removal of a double-lumen hemodialysis catheter. Emergent coronary angiography revealed air bubbles obstructing the mid-segment of the right coronary artery with slow flow phenomenon distally. The patient expired due to myocardial...
