Case Study. A 56-year-old male with severe nonischemic cardiomyopathy and recurrent ventricular tachycardia (VT) presented to our cardiology clinic with complaints of intermittent palpitations and several implantable cardioverter defibrillator (ICD)…
Case Report. A 65-year-old male with no known history of coronary disease presented with dyspnea on exertion and electrocardiographic (ECG) changes suggesting an old inferior infarct. Stress testing suggested ischemia based on ECG criteria. The patie…
Technological advancements have revolutionized the field of interventional cardiology by introducing newer devices and better pharmacological agents. The incidence of cardiogenic shock (CS) complicating acute myocardial infarction (AMI) remains the m…
While contemporary percutaneous coronary intervention (PCI) is predominantly a stent-based strategy, other modalities are occasionally used in lieu of or in addition to stents. Rotational atherectomy uses a high-speed rotating bit to pulverize plaque…
Percutaneous diagnostic and therapeutic cardiovascular procedures rely on intravascular use of iodinated radiocontrast agents for visualization in the cardiac catheterization laboratory. The use of radiocontrast agents has been associated with the de…
HIV Disease Human immunodeficiency virus (HIV) infection results from one of two similar retroviruses (HIV-1 and HIV-2) that destroy CD4+ lymphocytes and impair cell-mediated immunity, affecting multiple organ systems, increasing the risk of certain…
Case Presentation. A 58-year-old male presented with substernal chest pain that started while mowing his lawn. The chest pain radiated to the left shoulder and was not relieved with sublingual nitroglycerin. He had controlled hypertension and type II…
Significant left main coronary stenosis occurs in 5–7% of patients undergoing coronary angiography.1,2 Patients with “unprotected” left main coronary artery (ULMCA) disease treated medically have an estimated 3-year mortality rate of 50%.3,4 Since c…
Advances in interventional cardiology are reflected in the increased complexity of percutaneous coronary interventions (PCI). This leads to an increasing use of fluoroscopic guidance in these procedures with a concomitant increase in concern regardin…
Endovascular treatment has become the predominant method of revascularization for arterial obstructive disease for both coronary and peripheral vascular disease. As such, radiation exposure and fluoroscopy times during percutaneous coronary and perip…
