Cilinical history |
A 57-year old non-diabetic, normotensive, dyslipidemic gentleman was admitted to our hospital with unstable angina. He was a ex-smoker. Three months ago, he received PCI on the distal main to proximal LAD, and prox to distal LCX with Xience-V stents, 3.5/12mm and 3.0/20mm, respectively. His physical examiniation was normal and cardic enzymes were normal. His ECG and chest X-ray were unremarkable. Echocardiography reveals no gross regional wall motion abnormality with LVEF ~61%. |
Coronary angiographic findings |
1) Rt. coronary angiography showed diffuse 30-40% stenosis from proximal to mid part of right coronary arery (RCA). ( Movie 1) |
Procedure |
A 7F sheath was inserted through right femoral artery and a 7 F JL4 guiding catheter was engaged in left coronary artery. An 0.014¡± BMW guidewire was positioned in the LAD. From IVUS exam, It was revealed severely stenotic lesion with an eccentric mixed plaque (Figure 1). We performed a direct stenting with a 4.0/15 mm Xience-V stent at 14atm(4.28) (Figure 2). Because post-pocedural IVUS exam showed good apposition and adequate stent expansion (Figure 3), additional balloon inflation was not done. Final angiogram showed the procedure was successful (Figure 4, Figure 5). |
