CTO Coronary Perforations

Utility of CT Angiography to Guide Coronary Intervention of CTO.

SEE PAGE 804 T he procedural success rates of percutaneous intervention for chronic total coronary occlusions (CTOs) over the past decade have been increasing, driven by the development of specialized guidewires and microcatheters and the introduction of new technical strategies, including antegrade subintimal re-entry and the retrograde transcollateral approach. An ongoing challenge is to sele...

Pericardial covered stent for coronary perforations.

OBJECTIVES To evaluate initial and long term results of coronary perforation treatment with pericardial covered stent. BACKGROUND Iatrogenic coronary perforation is a rare life threatening complication of percutaneous coronary interventions (PCI) occurring in 0.1-0.8% of cases. Covered stents are the mainstay of therapy for coronary perforation. However, polytetrafluoroethylene covered stents...

Coronary artery perforations: four different cases and a review.

Coronary artery perforation (CAP) is a rare but feared complication of percutaneous coronary intervention. With the advent of new devices and technologies, interventionalists attempt more complex lesions, including more calcified or tortuous vessels and chronic total occlusions, which increases the incidence of CAP. A short literature review, in addition to four cases of CAP, is presented in th...

Should all coronary artery perforations be treated immediately?

Recurrent Coronary Perforations in an Aneurysmal Coronary Artery Treated with Covered Stent

An elderly hypertensive lady presented to us with acute coronary syndrome; an angiogram revealed total thrombotic occlusion of large left circumflex artery. After thrombosuction, there was proximal tight stenosis followed by an aneurysmal segment of the culprit vessel that was stented successfully. Subsequent post-dilatation at the site of aneurysm produced a large perforation, which was sealed...
