Clinical Information

Patient initials or Identifier Number

Mr z

Relevant Clinical History and Physical Exam

A 55-Year-Old Male with underlying Diabetes, Hypertension and Active Smoker. Presented to a District Hospital with Chest pain and Diaphoresis. Based on His ECG and raised Trop T a diagnosis of NSTEMI was made and he was admitted for treatment. However, patient complain of persistent chest pain in ward despite on anti- anginal medication  Stable Under Room Air Bp 110/80 mmHg PR 80 bpm  In view of persistent Chest pain, he was referred to us for an urgent angiogram. 

Relevant Test Results Prior to Catheterization

Fbs 8.1 LDL 3.2  other bloods parameters unremarkable 
Echocardiography showed EF 50% , preserved wall thickness 

Relevant Catheterization Findings

Critical Severe LM Stenosis 99% Ostial LAD 80% mLCX CTO ( collateral from diseased LM ) - ipsilateral anomalous RCA arising from LCC - mRCA CTO giving ipsilateral collateral 
Summary Severe 3VD with High Synthax score  Plan for Urgent Inpatient bypass surgery (CABG )
however at recovery bay while awaiting bed for admission patient developed sudden chest pain ,became less responsive with ECG changesdecided for urgent Primary Left main Revascularization as we do not have an inhouse cardiac surgeon 


Interventional Management

Procedural Step

Femoral approach 7FrEngaged with Short tip JL 4.0 wired into Ramus branch with no touch technique Runthrough floppy into LAD Predilate Left Main stenosis with Sapphire 2.0 x 15mm --> no more chest pain IVUS run into LM - LAD to asses plaque morphology  and identify landing zone Decide to intervene CTO LCX first since it has collateral from diseased LM risk of occluding collateral during LM stenting ( Plaque shift )During CTO  wiring chest pain again hence used scoreflex balloon 3.5 x15mm  to further prepare lesion in the left main.Initially wired using  Fielder XTR in a Finecross Microcatheter unsuccessful then escalated to Gaia 1st successfully crossed CTO lesion and exchange with Sion GW via balloon trapprepare lesion at LCX with scoreflex balloon 3.0 x 15mm deployed DEB sequent please 3.0 x 30mm @ nominal mLCXIVUS run into LAD decided for provisional stentingIdentify landing zone before Diagonal ( to prevent jailing retroflex Diagonal )Noted only one Diagonal arising from LAD supplying the anterior lateral wall hence its an important Diagonal cant risk losing proceed with DES 3.5 X 26mm resolute onyx of LM stenting Rewired LCX and Ramus using Dual Lumen to ensure wire within Stent Struts and not entangled during rewiring Final POT with 4.5 X 10 mm @ 28 atm Final IVUS good expansion , no dissection well apposed 
Post procedure he remained well Inotropes weaned off no chest pain ,ambulating discharged home 48hours later because we have arranged for an Urgent CTCA to assess the RCA anomaly 


Case Summary

1. IVUS in LM Intervention should be made mandatory as its usage help to decide:     - Plaque morphology     - Choose appropriate stent and balloon size     - Identify landing zone < 50% burden    - Assess side branch as in this case allowed us to decide on provisional stenting  rather then 2 stent technique
2. Operator Experience and Expertise with imaging is important to get equivalent to a CABG like outcome 
CTCA confirm RCA is anomalous arising from Left coronary cusp with low interatrial course and mRCA CTO with ipsilateral collateral.He has quit smoking and remained asymptomatic till today and is on Guideline Directed Medical Therapy and is back to his routine job as a Rubber Tapper.
