Abstract：
:Spontaneous rupture of coronary arteries as well as coronary perforation during percutaneous interventions are rare but potentially life-threatening incidents often resulting in emergency surgery. Frequency of acute perforation due to therapeutic catheterization varies according to the devices employed. With conventional balloon angioplasty it is estimated to be 0.1 to 0.2% whereas substantially higher rates of up to 3% have been reported with the use of so-called "new devices" (i.e. directional atherectomy, rotablation, excimer laser angioplasty or extractional atherectomy). Interventional strategies for nonsurgical treatment of acute coronary perforations during catheterization procedures have been developed. In recent times, availability of coronary stent-grafts allows for a percutaneous resolution of acute perforations while maintaining vessel patency. Whereas iatrogenic perforations in the catheterization laboratory may thus be treated immediately at the site of their occurrence, rupture of pre-existing but potentially unknown coronary pathology frequently is associated with a diagnostic interval, giving rise to serious clinical events (i.e. myocardial infarction, cardiac tamponade, malign arrhythmias or sudden death). It may be warranted to advocate prophylactic treatment of rupture-prone coronary conditions even on incidental diagnosis. This can either be performed by cardiothoracic surgery or, in suitable cases, by interventional therapy. Implantation of coronary stent-grafts could prove to become the therapy of choice due to its technical facility, safety and the short length of hospital stay associated with it. Before general recommendations can be made, however, as to the extension of indication for these novel coronary devices, further clinical studies encompassing long-term clinical and angiographic follow-up are needed.
