Interventional Management

Procedural Step

Right femoral access was taken. EBU 7 Fr guide was engaged in LM. Fielder FC 0.014 wire was parked in distal LCX. Wire could not be parked in LAD as LM was diseased and calcified. OTW Finecross Microcatheter was parked in distal LCX. Fielder FC wire was exchanged with 0.009 ROTA exchange length wire and parked in distal LCX. Finecross was removed. OTW 1.5 ROTA burr was taken and rotablation was done at 1,80000 RPM from LM to Mid LCX. After 2-3 runs, burr crossed the lesion. Then wire and burr were removed. Then Fielder FC was parked in distal LAD and using Finecross ROTA wire was exchanged. Same 1.5 burr was taken and 2-3 runs were done in LM-LAD. ROTA wire was exchanged with Fielder FC and 2nd Fielder FC was parked in Distal LCX. Both vessels were dilated with 2.5 mm  Semi-compliant balloons up to 15 atm. 4x40 mm DES was deployed in LM-LCX at 14 atm with wire jailed in LAD. Subsequently wire was removed from LAD and repositioned across the struts and parked in distal LAD. LCX was dilated with 4x12 mm NC @15 atm and LM WITH 4.5X12 mm @15 atm. Now over LAD wire 1.5 NC and subsequently 2.5 NC were taken and struts were dilated. 2nd DES 3X40 mm was deployed across the struts of LM-LCX stent with 1 mm struts protruding in LM-LCX stent. Now with 2 balloons 4x12 mm NC and 3x12 NC were taken and FKB was done. LAD was dilated with 3x12 mm throughout its length. A good TIMI III flow was noted with no complications. Patient was discharged after 2 days.

Case Summary

PTCA in a densely calcified Left main triple vessel disease is always a challenge, especially when diffuse disease where putting graft is not possible due to poor targets. A thorough understanding of anatomy is essential as calcified arteries always are fragile and need careful handling use of technology. Especially rotablation is a good tool but conceptual understanding is a must. From our case points which are clear are:1) quick decision making and clear anticipation of complication and their management is a must to attempt this case.2) technically sound mind and hand are required specially knowing concepts about rota is a must.
