Use of the radial artery for coronary angiography was first reported by Campeau in 1989.1 Since then, this approach has become more popular and has been extended to coronary interventions, particularly with the use of aggressive antithrombotic therap…
More than 25 years after the introduction of angioplasty, percutaneous recanalization of coronary artery chronic total occlusions (CTOs) remains a technical challenge with a lower success rate than most other lesions attempted.1 The presence of a CTO…
Atherosclerosis is a chronic inflammatory reaction of the arterial wall. The etiopathogenesis of atherosclerosis is multifactorial and includes inflammatory, infectious, metabolic and immune system involvement. Accelerated atherosclerosis is the mali…
Left ventricular-to-right atrial communications are rare types of ventricular septal defects known collectively as the Gerbode defect.1 Acquired forms of this defect have been described as a complication of infective endocarditis due to septal perfor…
Off-pump coronary bypass surgery has emerged as an alternative to conventional coronary bypass surgery (CABG) in recent years. This involves the creation of an anastomosis on a normothermic, beating heart while blood flows down partially occluded cor…
Mitral annuloplasty with Cosgrove-Edwards ring is a widely accepted and less morbid surgical alternative to mitral valve replacement in a selected group of patients.1,2 Injury of the left circumflex artery during suture placement is unusual but has b…
Case Presentation. A 65-year-old female with no known coronary artery disease presented with acute chest tightness and shortness of breath a few days after the death of her husband. She had a personal history of smoking and hypertension, treated wit…
Contrast-induced nephropathy (CIN) is a common problem after cardiac catheterization and percutaneous coronary intervention (PCI), and is associated with substantial morbidity and mortality.1–3 The etiology of CIN has not been clearly delineated. Ren…
Several randomized studies with bare-metal stents (BMS) have demonstrated the feasibility of direct stenting in a high percentage of coronary lesions, with low crossover rates of approximately 6%.1–13 Most studies have failed to detect significant di…
Percutaneous coronary intervention (PCI) is a mainstay in the management of acute myocardial infarction (AMI).1 However, despite major improvements in technical and pharmacologic means, including stent implantation and the use of potent antiplatelet…
