[Coronary artery perforation with rotational coronary atherectomy].
The authors describe a rare case of circumflex coronary artery perforation during rotational coronary atherectomy complicated with cardiac tamponade and good outcome. The possible causes of perforation are discussed and the burr oversize (burr/artery ratio was 0.58) was refused. Shortening and artery plicature (accordeon effect) might have been the cause of this event. Quantitative measurement was made in order to strengthen this hypothesis. It is emphasized the importance of selecting lesions that should be submitted to rotational coronary atherectomy.
