These findings demonstrate that in patients with unstable ischemic syndromes undergoing coronary angioplasty, the use of ionic low osmolar contrast media reduces the risk of ischemic complications acutely and at 1 month after the procedure. Therefore, low osmolar ionic contrast media should be strongly considered when performing interventions in patients with unstable angina or myocardial infarction.

In patients with stenoses in saphenous vein bypass grafts, TEC atherectomy is limited by the frequent need for adjunctive balloon angioplasty to achieve adequate lumen enlargement and to manage TEC atherectomy-induced complications. Although the incidence of serious clinical complications is similar to that of other percutaneous interventions in vein grafts, there is a high incidence of restenosis and late vessel occlusion. Prospective randomized studies are needed to determine the best revascularization strategy for high-risk patients with old degenerated vein

Cor triatriatum dexter is a rare congenital anomaly in which an obstructive membrane is located in the right atrium. The detection usually occurs after the sequelae of systemic congestion, coagulopathy, and hepatic dysfunction have set in, leading up to a high surgical risk. A percutaneous balloon correction of cor triatriatum dexter in a patient with advanced right-sided congestive symptoms and hepatic dysfunction is presented. This efficacious method is an alternative to surgical correction and could be extended to the more common cor triatriatum sinistra.

The incidence of retained hardware components in the coronary artery tree is likely to parallel the growing number and types of percutaneous coronary revascularization procedures being performed. Management has extended from the conservative option of simply leaving behind the retained components to the more aggressive approach of surgical removal. A percutaneous method is described herein which offers the interventional cardiologist an alternative method of managing patients with retained wire fragments contained entirely in the coronary artery.
