Treatment of patients with hypertrophic obstructive cardiomyopathy (HOCM) and refractory symptoms remains a challenge.1 Surgical septal myectomy remains the classical approach for these patients.2 This therapy is associated with good initial results,…
Despite extensive advances in cardiology over the past 50 years, the definitive treatment for aortic stenosis remains unchanged. Aortic valve replacement, while employing enhanced prostheses, continues as an imperfect therapy with inherent risks and…
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…
Cardiogenic shock is the leading cause of death in patients with acute myocardial infarction (AMI) who reach the hospital alive.1,2 The reported incidence of cardiogenic shock in patients with AMI is 7–10%.1,3 The mortality rate in these patients is…
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…
