Mechanical distortion of a stent, even after successful implantation, may occur as a result of further coronary intervention such as balloon inflation of side branches through the stent struts, dilatation over a guidewire outside the stented lumen an…
Case Report. An 86-year-old female with a medical history of hypertension and hypercholesterolemia who was on medication complained of dyspnea, chest pain and shortness of breath that was relieved at rest. She had a positive stress test and her elect…
Anaphylaxis is a severe, life-threatening, generalized hypersensitivity reaction that is mostly mediated by IgE antibodies, often starting with erythema, urticaria and/or angioedema, and occasionally involving cardiovascular and respiratory systems.…
Case Report. An 81-year-old male with a prior history of open abdominal aortic aneurysm (AAA) repair using a tube graft (24 mm Hemashield Dacron, Meadox Medicals, Inc., Oakland, New Jersey) presented for treatment of a pseudoaneurysm. Ten years after…
Mechanical complications comprise the second leading cause of in-hospital mortality in patients with ST-segment elevation myocardial infarction (STEMI), especially in the elderly.1 Among them, ventricular septal rupture (VSR) complicates approximatel…
Drug-eluting stents (DES) have revolutionized modern interventional cardiology by providing distinct advantages over bare-metal stents (BMS) in reducing the risk of in-stent restenosis. Several randomized clinical trials have consistently demonstrate…
Elevation of biochemical markers of myocardial damage following percutaneous coronary intervention (PCI) is frequently observed,1–4 however, its significance remains controversial.5,6 Multiple reports have demonstrated a linear relationship between t…
The timing of, and risk factors for, very early (< 24 hours) major adverse clinical events (death, myocardial infarction [MI], urgent target vessel revascularization [uTVR], and major bleeding) following percutaneous coronary intervention (PCI) in…
Platelets play a crucial role in the pathophysiology, morbidity and mortality of coronary artery disease (CAD). It has been shown that platelet size, measured as mean platelet volume (MPV), correlates with their reactivity.1 MPV showing platelet size…
The recent introduction of cardiac troponin I (cTn-I) into daily routine practice allows for highly accurate, sensitive and specific determination of myocardial injury in patients with chest pain. Any increase in these markers implies myocardial necr…
