C58. Management of Ellis Type V RV Branch Coronary Perforation Using Handmade Covered-stent: a case report

Abstract

Abstract Coronary perforation is a rare but life-threatening complication of percutaneous coronary intervention (PCI) requiring urgent management including balloon inflation, thrombin, microcoils, fat embolization, autologous blood clots administration, heparin-reversing agent, covered-stent implantation, or surgery. We report a case of Ellis type V RV branch coronary artery perforation during PCI treated with a handmade covered-stent. A 69-year-old female presented with typical angina in three days. She was hemodynamically stable and no sign of congestion. Laboratory results showed leukocytosis, mild elevation of liver transaminase, elevated CK-MB level, mild hypoalbuminemia. ECG showed sinus rhythm with atrial bigeminy, late-onset inferoposterior and RV MI, and first-degree AV block. TTE revealed reduced LV systolic function (LVEF 45%), impaired LV relaxation, reduced RV function, marked LV hypokinetic in inferior, inferoseptal, apicoseptal, and inferolateral wall, and mild ischemic mitral regurgitation. DCA result showed 90 – 95% tubular stenosis in mid-LAD and total occlusion in proximal-RCA with grade V thrombus. She had an anomaly of RV branch angle that resembles the RCA so that the guidewire perforated the distal part of the RV branch artery. PCI was done using hydrophilic wire to distal RCA. Ellis type V perforation was found following multiple balloon inflation in RV branch. Perforation was managed with a handmade covered-stent using a Sirolimus-eluting stent with Tegaderm film. TIMI flow 3 was reached without thrombi or residual stenosis. In medical centers that have limited resources, handmade covered-stents can be used as an option after unsuccessful balloon inflation trial.
