The QCA Guided BVS Stenting
- Operator: Duk-Woo Park, MD
Case Presentation
A 66 year-old male patient was admitted for chest discomfort for 1 year ago. His coronary risk factor was ex-smoking and hypertension. He underwent coronary angiography from outside hospital. There was severe stenosis at proximal LAD. The physical exam was normal. The ECG and cardiac enzymes were unremarkable. We decided to stent with BVS.
Baseline Coronary Angiogram
  1. Left and coronary angiogram showed severe stenosis at proximal LAD and mild stenosis at proximal LCX ( Movie 1).
  2. The right coronary angiogram showed mild stenosis at PDA ( Movie 2).
Procedure
A 6 Fr sheath was inserted thorough right radial artery and, left coronary artery was engaged with a 6 Fr XB 3 guiding catheter. 0.014-inch BMW 190 cm wire was inserted into LAD. Predilation performed with Pantera LEO 3.5 x 15 mm balloon (Figure 1). We measured the proximal and distal reference vessels size by QCA. The proximal and distal reference vessel size were 3.74 mm and 3.60 mm. The minimal lumen size and lesion length were 1.23 mm and 24 mm. And then Absorb GT1 BVS 3.5 x 23 mm was successfully deployed at proximal LAD (Figure 2). And additional NC balloon was performed by using Nimbus Salvo 4.0 x 13 mm at proximal LAD. Final angiogram showed that the procedure was successful ( Movie 3, Movie 4).
