A Stent Misplaced in the Septal Perforating Artery: Right Ventricular Fistula, Interventricular Septal Hematoma, and Right Ventricular Outflow Tract Obstruction

Abstract

Coronary-cameral fistulas, though mostly regarded as congenital entities, have also been encountered as complications of major traumas and percutaneous coronary interventions (PCIs).11 Ohayon P, Matta A, Boudou N. A case report of an iatrogenic coronary cameral fistula treated by retrograde percutaneous coronary intervention. Eur Heart J Case Rep. 2020;4:1-6. doi: 10.1093/ehjcr/ytaa094.
https://doi.org/10.1093/ehjcr/ytaa094... On the other hand, interventricular septal (IVS) hematoma might potentially arise mostly during retrograde chronic total occlusion (CTO) interventions and has a benign course in this context.22 Abdel-Karim AR, Vo M, Main ML, Grantham JA. Interventricular Septal Hematoma and Coronary-VentricularFistula: A Complication of Retrograde Chronic Total Occlusion Intervention. Case Rep Cardiol. 2016;2016:8750603. doi: 10.1155/2016/8750603.
https://doi.org/10.1155/2016/8750603... Herein, we describe a challenging PCI complication (and its management strategy) presenting with IVS hematoma, right ventricular fistula, and right ventricular outflow tract (RVOT) obstruction due to a misimplanted coronary stent in the septal perforating artery (SPA).
