Clinical Information

Patient initials or Identifier Number

AR

Relevant Clinical History and Physical Exam

A 57-year-old female known case of diabetes and hypertension was admitted with a history of chest pain for 4 days. Pain was a central, compressive type, nonradiating. No family history of coronary artery disease. Vitals were stable.On systemic examination CVS- S1S2 normal, no added sounds, no murmur.RS- Air entry bilateral clear. No added sounds.

Relevant Test Results Prior to Catheterization

Hemoglobin- 11 gm/dlPlatelets- 2.8 Lacs Total count - 9000Blood urea - 13 mg/dlS.Creatinine- 0.8 mg/dlECG: Normal sinus rhythm, ST depression in antero lateral leads2D-ECHO- No regional wall motion abnormality. Ejection fraction - 50%

Relevant Catheterization Findings

Coronary angiogram showed
LM- Normal
LAD- Diffuse lesion in the mid segment (99% stenosis) with both antegrade and retrograde filling.
LCX- Sub total occlusion
RCA- 70 % lesion in the mid segment



Interventional Management

Procedural Step

1. EBU (Medtronic, USA) guide was used to engage the left coronary. 2. Miracle wire (Asahi, japan) tried to cross LAD along with the caravel microcatheter (Asahi, Japan).3. Check shot through caravel leads to retrograde dissection involving LM, LAD & LCX.4. As vitals were stable, LCX was opened using 2.5x36mm DES.5. Using the mini crush technique bifurcation stenting was done in LCX (3.5X16mm)and LM to LAD (4.0x20mm), followed by POT in LM.6. Fielder FC (Asahi, Japan) wire crossed in the lesion in LAD.7. Angio shot taken from RCA to confirm the position of LAD wire in the true lumen. Pre dilatation did using a 2.0x10 mm NC (Sapphire, CSI, USA) balloon.8. 2.5x48 mm DES was deployed from mid to distal LAD.9. Proximal to mid LAD stented with 3x32mm DES overlapping the distal edge of proximal stent and proximal edge of distal stent.10. Post dilatation from proximal to mid LAD done using 3.5x12 mm NC Balloon.11. Fielder FC wire reintroduced in LCX & ostium was dilated with 1.25x10 mm NC balloon.12. Final KBI done using 4.0x12mm NC in LAD and 3.5x12mm NC in LCX.13. TIMI 3 flow achieved



Case Summary

Nightmares in cath labs are rare especially when retrograde dissection is extending into the left main and origin of LCX, one has to be careful not to lose access to the main vessel and skillful enough to wire the side branch. Calm mind, and proper awareness of material and stenting techniques should be known to the operator in order to bail out patients from critical conditions and prevent mortality. Henceforth maturity and experience are required during critical complications which come with repeated practice and excellent exposure.
