Serial clinical and angiographic follow-up after phosphorylcholine-coated stent implantation.

The efficacy of drug-eluting stents (DES) has been proven, but concerns about late complications after DES have been raised. Polymers that do not increase inflammatory or hypersensitivity reactions which may contribute to late complications are needed for new generation DES. To evaluate the safety and efficacy of phosphorylcholine-polymer coating, we investigated serial clinical and angiographic outcomes after phosphorylcholine-coated stent placement.

Effectiveness of paclitaxel-eluting balloon catheter in patients with sirolimus-eluting stent restenosis.

Objectives: The aim of this study was to investigate the efficacy of a paclitaxel-eluting balloon (PEB) for the treatment of sirolimus-eluting stent (SES) restenosis.

Background: Because drug-eluting stents (DES) are being used in increasingly complicated settings, DES restenosis is no longer an uncommon phenomenon, and its optimal treatment is unknown.

Methods: This study was a prospective single-blind randomized trial conducted in 50 patients with SES restenosis.

Successful treatment in a case of acute myocardial infarction due to spontaneous coronary artery dissection.

Spontaneous coronary dissection is a rare cause of myocardial ischemia, myocardial infarction, and sudden death. In the present case, we performed stenting only of the severe stenotic lesion of the dissection with a short bare metal stent, and left the remaining long length of dissection vessel untreated. Six months after coronary stenting, follow-up angiography revealed complete healing of the coronary dissection and no significant in-stent restenosis.

Cor triatriatum sinister disclosed after diagnosis of acute myocardial infarction.

We present a case of cor triatriatum sinister diagnosed occasionally after acute anterior myocardial infarction. For management of the acute myocardial infarction (AMI), urgent reperfusion therapy was successfully performed through the left anterior descending coronary artery. Thereafter, no complication associated with AMI occurred.
