Case Presentation
A 55-year-old women was admitted with effort-related chest pain for one year. Her coronary risk factors were diabetes and hypertension. The physical examination was normal. The echocardiography showed normal LV systolic function(EF=68%) without RWMA.
Baseline Coronary Angiography
1. The left coronary angiogram showed discrete moderate stenosis at LM ostium and diffuse moderate stenosis at proximal to mid LAD ( Movie 1, Movie 2).
2. The right coronary angiogram showed mild stenosis at proximal to mid RCA.
Procedure
An 8 Fr sheath was inserted through right femoral artery and the left coronary ostium was engaged with a 7Fr JL 4.0 catheter with side hole. Two 0.014 inch BMW wires were inserted into the LAD and LCX. And then, they performed FFR measurement in the proximal LCX and the proximal LAD (Figure 1, Figure 2). FFR value was 0.89 and 0.81, respectively. As a result, LM ostium lesion was considered unsuitable for PCI and they decided to manage the patient with medical treatment.
