[Kissing-stent technique for the treatment of spontaneous coronary artery dissection].
A 60-year-old woman referred to our hospital because of increasing dyspnea and angina. Her past history included an anterior myocardial infarction, associated with a large coronary dissection of the proximal left anterior descending coronary artery. The infarction resulted in a ventricular aneurysm which was treated with surgical excision without coronary revascularization. Coronary angiography showed a linear filling defect involving the left anterior descending coronary artery. Intracoronary ultrasound revealed a long intimal tear dividing the artery into two separated lumens. A kissing-stent technique was used to preserve the anatomical and functional integrity of the main vessel as well as of the diagonal branch. Two premounted stents were positioned covering the origin of both branches of the bifurcation. Simultaneous inflation of the two balloons created a metallic new-carina, 1 cm proximal to the bifurcation. Five months later the patient was readmitted with chest pain and repeat coronary angiography demonstrated a severe in-stent restenosis. Re-coronary angioplasty resulted in a good angiographic result. At 4 months from the last procedure there is no complaint of angina.
