Background: Iatrogenic aorto-coronary dissections following percutaneous coronary interventions (PCI) represent a rare but potentially life threatening complication. This restrospective and observational study aims to describe our in-house experience for timely diagnostics and therapy including cardiovascular imaging to follow-up securely high-risk patients with Dunning dissections.
Methods: Dunning dissections (DD) occurred during clinical routine PCIs, which were indicated according to current ESC guidelines. Diagnostic assessment, treatment and follow-up were based on coronary angiography with PCI or conservative treatment and cardiac computed tomography (cCTA) imaging.
Results: A total of eight patients with iatrogenic DD were included. Median age was 69 years (IQR 65.8-74.5). Patients revealed a coronary multi-vessel-disease in 75% with a median SYNTAX-II-score of 35.3 (IQR 30.2-41.2). The most common type of DD was type III (50%), followed by type I (38%) and type II (13%). In most patients (88%) the DD involved the right coronary arterial ostium. 63% were treated by PCI, the remaining patients were treated conservatively. 88% of patients received at least one cCTA within 2 days, 50% were additionally followed-up by cCTA within a median of 6 months (range: 4-8 months) without any residual.
Conclusion: Independently of the type of DD (I-III) it was demonstrated that cCTA represents a valuable imaging modality for detection and follow-up of patients with DDs.

Iatrogenic Aorto-Coronary Dissection: A Rare Complication With Fatal Prognosis.

Iatrogenic aorto-coronary dissection (IACD) is a rare complication of interventional and surgical cardiac procedures, with a very high mortality burden. Here, we report the case of a 71-year-old female with a past medical history of paroxysmal atrial fibrillation, mild to moderate aortic insufficiency, hypertension, and hyperlipidemia, who presented with classic anginal symptoms and underwent a cardiac catheterization, during which she suffered Iatrogenic right coronary artery (RCA) dissection and ascending aortic dissection resulting in sudden death. IACD is a rare complication, with a fatal prognosis.

Objective: Iatrogenic coronary artery dissection is a complication of coronary intimal injury and dissection due to improper catheter manipulation. The impact of tear direction on the prognosis of coronary artery dissection (CAD) remains unclear. This study examines the hemodynamic effects of different tear directions (transverse and longitudinal) of CAD and evaluates the risk of thrombosis, rupture and further dilatation of CAD.

Objectives And Background: Iatrogenic aorto-coronary dissection (ICD) is one of the most feared complications of interventional cardiology. Although rare, it is characterized by anterograde coronary ischemia and a concomitant aortic dissection, with potentially fatal consequences.
Methods: We present an example case of IACD and an accurate case-series review of the literature including 125 published cases.

Catheter-induced aortic dissection during coronary angiography and Percutaneous Coronary Intervention (PCI) is a relatively infrequent, but potentially life-threatening complication. Patients who suffer this complication may require emergency aortic surgery. More recently, reports of treating the ostium of the dissected coronary artery have emerged as an alternative therapeutic option.
