Clinical Information

Patient initials or Identifier Number

2761994

Relevant Clinical History and Physical Exam

65 year old gentleman admitted with history of acute onset of chest pain which was retrosternal, compressive in nature, radiating to both shoulders. He was a known HTN. He was diagnosed with ACS (Anterior Wall Myocardial Infarction). Patient was lysed with 40mg inj. tenecteplase. Pain was reduced. He had one episode of ventricular tachycardia revert with antiarrythmic drug. Later posted for CAG.On physical examination vitals were within normal range. Systemic examination was normal. 

Relevant Test Results Prior to Catheterization

Hb- 16.5 g/dlPlatelets- 2.97 thousand/uLBUN- 10 mg/dlS.Creatinine- 0.7 mg/dlTroponin I - 9.91 ng/ml2D-ECHO- Mid anteroseptum, apical septum, LV apex, apical inferior wall, mid and apical anterior wall hypokinetic. Mild LV systolic dysfunction (EF- 45%) with grade I diastolic dysfunction. Mildly dilated LV, mild MR.ECG- ST elevation in V2-V6  with reciprocal changes in inferior leads.LDL- 226 mg/dl, TG- 239 mg/dl, S. Cholesterol- 327 mg/dlRecently diagnosed with DM II (HbA1c- 9.5%)

Relevant Catheterization Findings

Distal LM was 50% diseased.
Proximal LAD had 90% disease. Mid and distal segments had no flow limiting lesion. Branching vessels had non significant disease.
Proximal LCX had 90% lesion followed by long long lesion with maximum severity of 80% stenosis.
RCA was a dominant vessel with 90% focal lesion in mid segment.

Interventional Management

Procedural Step

-RCA hooked with 6F JR 3.5 guiding (Merit, USA)-Runthrough wire (Terumo, Japan) used to cross the lesion-Pre dilatation done with 1.5x10mm SC (Terumo, Japan) & 2.5x12mm NC balloons (Terumo, Japan)-Lesion stented with 3.5x20mm DES (Boston scientific, USA )-Post dilatation done with 3.0x8mm NC balloon(Terumo, Japan)). TIMI III flow achieved-Left coronary hooked with 7F BL 3.5 catheter (Terumo, Japan)-Runthrough wire (Terumo, Japan) and Fielder FC wire (Asahi, Japan) were crossed in LAD & LCX respectively-Predilatation in LCX done with 3.0x8mm NC balloon (Terumo, Japan) and in LAD with 3.0x10 NC balloon (Brosmed, China).-3.0x10mm cutting balloon (Brosmed, China) used to predilate proximal LCX and from LM to LCX-Using 3.0x20mm DES (Boston scientific, USA) ostioproximal LCX stented.-Using step crush technique with 3.0x10mm NC balloon (Brosmed, China) in LAD proximal struts of LCX stent were crushed.-LM to LAD stented using 3.0x34 mm DES (Medtronic, USA). Distal displacement of stent noted while deploying it.-LCX rewired and ostium was post dilated with 1.5x10mm SC balloon (Terumo, Japan)-Post dilatation in LAD & LCX done using 3.0x10mm NC (Brosmed, China) & 3.0X8mm NC (Terumo, Japan)  respectively.-KBI done using same balloons used for post dilatation in LAD & LCX.-Ostial LM was stented using 4x8mm DES (Medtronic, USA) followed by post dilatation and aortic flurrying with stent balloon only. - TIMI III flow achieved- IVUS done pre and post stenting

Case Summary

- Complete revascularization can be done in stable ACS patients- Never miss left main ostium in LM stenting- Cutting balloon should be used for fibrotic lesions- Advise patient to avoid deep breathing during ostial stenting as it may displace the stent while deploying- Always try to use IVUS in LM and bifurcation lesions for better assessment of disease - Planned 2 stent technique should be preferred over provisional stenting in good size vessels
