A 60-year-old man presented with new onset left sided chest pain on exertion and relieved by rest. Stress MPI showed mild-moderate anteroseptal and inferior ischemia. Echocardiogram showed normal LVEF with 56%.
Medical History: Hypertension, Hyperlipidemia, End-Stage renal disease on hemodialysis, Ex-smoker
The coronary angiogram showed a significant disease in ramus artery with 80-90% stenosis.
Since the lesion is not calcified or tortuous, it can be classified as ACC/AHA Type A lesion (simple lesion).
Plan to use workhorse wire, followed by predilation and stent placement.
STEPS
We used VL 3.5 guide catheter (Mach 1: Boston Scientific).
For Type A lesion, we can use any workhorse wire which has a soft tip with hybrid coating (hydrophilic coating with distal hydrophobic coating) (i.e. Runthrough, Sion Blue).
We used Runthrough to cross the lesion, followed by predilatation using Trek NC 3/12mm balloon.
Then, Xience Sierra 3.25/18mm was placed in the ramus artery followed by post-dilatation using Trek NC 3.5/12 mm balloon.
A final angiogram showed an excellent result.
Learning Points
In Type A lesion intervention, the goal is to cross the lesion and advance the wire to the distal lumen softly and atraumatically.
Any workhorse wire can be used per the operator’s preference to perform the coronary intervention.
