Coronary angioplasty on an impassable calcified stenosis using a buddy balloon technique.

We report our experience in coronary angioplasty on a calcified lesion that was not passable with balloon catheters despite an adequate preangioplasty lumen size on angiogram and intravascular ultrasonography study. The angioplasty was successfully performed with a simple and inexpensive buddy balloon technique.

Treatment of long, diffuse in-stent restenosis with sirolimus-eluting stents.

Treatment of long, diffuse in-stent restenosis remains a therapeutic challenge. We report the successful use of multiple sirolimus-eluting stents (three 33-mm long stents) in a long, diffuse in-stent restenotic lesion. No major adverse cardiovascular events, including acute/subacute/delayed stent thrombosis, were noted at ten months.

Left ventricular performance in patients with severe acute respiratory syndrome: a 30-day echocardiographic follow-up study.

Background: Severe acute respiratory syndrome (SARS) is characterized by an overaggressive immune response. Myocardial performance may be impaired in cytokine-mediated immune reactions.

Methods And Results: Forty-six patients with established clinical diagnosis of SARS were studied prospectively.

Carotid stent-supported angioplasty in a patient with symptomatic and critical aortic stenosis.

We report a successful carotid angioplasty in a patient with symptomatic and critical aortic stenosis. The safety and feasibility of this technique in this scenario have not been well established and reported. With careful planning and technique, we believe the procedure should be safe and feasible.
