Collaterals are vessels structured as a connecting network between different coronary arteries. They are probably remnants of the embryonic arterial network and may develop under influence of various stimuli. The pressure gradient between the normal…
Evidence suggests that collateralization may be impaired in diabetics.1,2 This issue of the Journal provides interesting new support for these data.3 The factors responsible for deficient collateral development in diabetes are incompletely understood…
Thrombolysis in myocardial infarction (TIMI) frame count (TFC) is a reproducible, objective and quantitative index of coronary flow that allows standardization of TIMI flow grades.1 The quality of coronary flow restored by percutaneous coronary inte…
We present a case in which a computerized tomographic scan was initially misleading, resulting in confusion over the diagnosis and treatment of a progressively increasing pulsatile abdominal mass. Angiography further clarified the situation, and led…
Evidence accumulated along converging lines of investigation indicates that acute coronary syndromes are due to the activation of a vulnerable plaque. The tools available for interventionalists to identify such vulnerable plaques are currently limite…
Percutaneous transluminal angioplasty and stent implantation to treat renal artery stenosis have been proven to be beneficial in atherosclerotic lesions.1,2 The indications for the treatment of renal artery stenosis (RAS) are renovascular hypertensio…
LG: What are you doing now? What are your primary areas of interest? FC: As you know, I am a vascular surgeon by training and background. However, along with a few of my peers, I began to develop an interest in performing percutaneous non-surgical pr…
Dear Readers, This issue of the Journal of Invasive Cardiology includes original research articles, commentaries, case reports, an article from the Journal special section “Acute Coronary Syndromes,” a special CME offering and an interview with Dr.…
Percutaneous coronary intervention (PCI) has significantly changed the management of coronary artery disease. According to the American Heart Association, an estimated 539,000 percutaneous transluminal coronary angioplasty (PTCA) procedures were perf…
Coronary vascular brachytherapy reduces recurrent restenosis and is a valuable adjunct to percutaneous coronary intervention (PCI) in the treatment of in-stent restenosis (level of evidence A).1–3 Although both late (6 month) coronary restenosis and…
