Background Both high on-treatment platelet reactivity and periprocedural myocardial infarction (MI) are associated with adverse events following percutaneous coronary intervention (PCI). The optimal method of quantifying platelet reactivity remains controversial….
Background Primary percutaneous coronary intervention (PPCI) for STEMI is beneficial if performed in a timely manner. Conflicting data exist regarding potential treatment delays for PPCI performed during off hours. We…
Introduction Anomalous origin of the circumflex (Cx) coronary artery from the right sinus of Valsalva is the most common coronary anomaly and is usually considered “benign.” Due to the acute…
Background Microvascular dysfunction (MVD) after acute myocardial infarction (AMI) may predict progressive left ventricular (LV) dilatation. A dual-sensor (pressure and Doppler velocity) guidewire has an ability to evaluate MVD quantitatively….
Aim Patients with coronary artery bypass grafting (CABG) represent a sizable portion of those undergoing percutaneous coronary intervention (PCI): in many instances, it is unclear whether performing PCI on the…
Background The Endeavor (Medtronic) zotarolimus-eluting stent (ZES) has shown favorable results in reducing target lesion revascularization (TLR) and vessel failure (TVF) in several registries and randomized trials. We report our…
Objective The goal of this study was to examine the hospital outcomes of high-risk percutaneous coronary intervention (PCI) performed with hemodynamic support by intraaortic balloon pump (IABP), Tandem Heart (TH)…
Background Recent studies demonstrated the ineffectiveness of kissing balloon inflation (KBI) in one-stent strategy for the coronary bifurcation lesion (COBIS and Nordic-Baltic III). However, there has not yet been standardization…
Background Precise stent positioning at ostial and bifurcated coronary stenosis is difficult due to vessel overlap and/or foreshortening. The Szabo technique (SzT) is a simple way to deal with these…
Background Previous demographic studies have revealed different CAD patterns among different population groups, with a more extensive and diffuse disease pattern among Egyptian/Arab patients particularly in a young age. These…
