Relevant Clinical History and Physical Exam

A 69 year-old female presented Non ST Elevation Myocardial Infarction  came to our hospital. Cardiovascular  risk factor was Hypertension.The ECG showed ST depression at anterior lead. Her physical examination was unremarkable. 

Relevant Test Results Prior to Catheterization

Troponin level was elevated . Echocardiography showed preserved LVEF.

Relevant Catheterization Findings

Very short left main. There were ambiguous lesion in proximal LAD which appeared as hazy severe eccentric stenosis. The LCx was normal. The RCA demonstrated  severe calcification.

Interventional Management

Procedural Step

A 7Fr JL 3.5 guiding catheter was engaged into LCA ostium. Base on her ECG, we decided to do early invasive strategy to LAD which we considered  as the culprit vessel. Following predilation using 2.0 x 15 mm semi compliance balloon,OCT was used to guide lesion preparation. OCT showed eruptive calcified nodule with fibrous cap disruption at haziness area, calcified lesion with arc > 270 0, Calcium Volume Index Score was 4.Based on OCT result we decided to do rotablation. Rotablation with 2.0 mm burr done with 180.000 rpm. Additional lesion preparation using 2.5 x 15 mm Scoring Balloon inflate up to 18 atm. GW Runthrough floppy was placed to D2 as jailed wire. Two overlapping 2.5 x 38 mm and 3.0 x 33 mm DES were implanted at mid-proximal LAD. OCT evaluation post stenting showed under expansion stent and there were malapposition and proximal LAD. We decided to optimize the implanted stent using 2.5 x 15 mm balloon at mid and 3.5 x 12 mm Non Compliance Balloon (NCB) at proximal. OCT evaluation showed there was good expansion (MSA 5.84 mm), but there was mal apposition at proximal part, then NCB 3.5 x 12 mm delivered and inflate high pressure. FinalAngiogram showed good result with TIMI 3 Flow.

Case Summary

      Calcified nodule recognized as one of the underlying mechanisms of acute coronary syndrome (ACS). It  could impact on stent deployment. Intracoronary imaging usage is very crucial to determine the ambiguous lesion in ACS and to strategize the planning and optimizing  PCI. Rotational atherectomy should be considered as the treatment of calcified nodule in ACS.
