Clinical Information

Patient initials or Identifier Number

Relevant Clinical History and Physical Exam

Mr Fu was a 72-year-old gentleman with history of hypertension and hyperlipidemia. He complained of exertional angina for 6 months. Physical examination was grossly unremarkable. ECG showed sinus rhythm. 

Relevant Test Results Prior to Catheterization

Echocardiogram showed hypokiensia over anterior wall and basal septum, with an impaired LVEF of 45%. 

Relevant Catheterization Findings

Coronary angiogram showed triple vessel disease with distal left main bifurcation disease (medina 1,1,1). Ostial to mLAD diffuse 80% stenosisOstial to mLCx diffuse 80% stenosisRCA dominant, diffuse moderate to severe steosis 

Interventional Management

Procedural Step

F7 EBU 3.5 was engaged to LMS. Sion wire to left anterior descending artery (LAD), Runthrough extraFloppy to left circumflex artery (LCx). Altaview IVUS to LAD and LCx for vessel sizing and lesion analysis.
We decided to perform stenting to mid LAD first, then treat the left main stem (LMS) bifurcation with DK Crush technique. Lesion preparation to LAD was done with Lacrosse NSE 2.0/13 at 14-24 atm. Stenting to mLAD was done with Ultimaster Nagomi 2.5/44 at 9-14 atm.
However, patient developed chest discomfort. Coronary angiogram showed type B coronary artery dissection LMS to LAD [see fig 1]. We decided to proceed to DK Crush to LMS bifurcation.  Intended stenting to LCx with with Ultimaster Nagomi 2.25/38 at 10atm. [see fig 2]. Intended Crushing with Accuforce 3.5/15 to LMS-LAD.
Coronary angiogram showed unintended too distal position of LCx stent, missing the ostial LCx lesion. [see fig 3]We decided to proceed to stenting to LMS-LAD. Kissing balloon inflation (KBI) to bifurcation with 3.0/15 NC SeQuent Neo and 2.5/15 NC Pantera Leo at 8atm. Stenting to LMS-LAD with Ultimaster Nagomi 3.0/33 at 12 atm. KBI to bifurcation with 3.0/15 NC SeQuent Neo and 2.5/15 NC Pantera Leo at 8atm. TIMI3 flow was maintained, and dissection was controlled
For the ostial LCx lesion, we decided to use drug-coated balloon angioplasty (DCB). DCB to ostial LCx with 2.5/15 Magic Touch at 12 atm. 
Final angiogram and IVUS showed good result.


Case Summary

Dissection is a well known complication which may progress and limit the coronary blood flow. Rapid identification is important.
In our case of unintended too distal landing of side branch stent, we chose to use DCB as a strategy to avoid extra stent layer and prevent late lumen loss. The patient will have coronary angiogram for restudy. In case of suboptimal result of ostial LCx lesion, further stenting can be perform.
Prevention is still the key to optimise the result of revascularization.
