Clinical Information

Patient initials or Identifier Number

Z. A.

Relevant Clinical History and Physical Exam

- 65 years lady, DM, HTN - Presented with high-risk NSTEMI and was referred for urgent coronary angiography- borderline hemodynamics with bilateral basal crepitation-  She rapidly deteriorated and developed pulmonary edema and she was electively intubated.- She was immediately rushed to the Cath lab

Relevant Test Results Prior to Catheterization

Echo: severely impaired LVEF = 20% with moderate MRShe is known to have multi-vessel CAD for 3 years and she refused any intervention at that time.

Relevant Catheterization Findings

Left main ostial and distal severe stenosis (Medina 1-1-1)LAD: shows tight ostial calcific stenosis followed by mid segment long severe stenosisLCX: retroflexed origin, ostial severe stenosis at the origin of 1st OM branch. The LCX shows proximal long significant stenosisRCA: CTO at the ostium with faint TIMI I and retrograde filling via contralateral septal collateralsHeart team was urgently held and she was turned down by surgeons due to frailty and severely impaired LVEF

Interventional Management

Procedural Step

> IABP was inserted- Engagement of the LM was difficult due to ostial lesion, it was fished by a BMW wire and the guiding was positioned over it.- Sion wire over corsair microcatheter was steered successfully into the 1st OM branch- Difficulty to wire the LCX proper- Predilatation for distal left main/ostial LCX and LAD, after which the LCX trunk was wire successfully. > IVUS assessment was done for proper vessel sizing- Further proper preparation by non-compliant balloons   - PCI to distal LCX and mid LAD followed by PCI to LM-LAD and LCX by cullotte technique- followed by kissing balloon inflations and final POT (3 KBI and 3 POTS were performed, one after each stent) - Final result was good with TIMI III flow > Post PCIIVUS assessment- MSA at LAD was7.9 mm2 at LCX, 9.2 mm2 at LAD, 12.5 mm2 at LMT- Patient was transferred to ICU on high dose of Noradrenaline and adrenaline- Extubated after2 days and IABP removed at day 4 > She suffered hectic ICU course:- She developed CIN requiring dialysis for 4 sessions- She developed 2attacks of hematemesis (stress ulcer ) and received PRBCS- She developed hospital acquired pneumonia and received culture-based antibiotics. > She was discharged home after 3 weeks.- She came for follow up at outpatient clinics after 2 weeks and after 40 days > Her LVEF recovered completely, she is doing fine, ambulatory and symptom-free.A long story with fruitful end

Case Summary

CHIP is not uncommon in daily practice.CHIP PCI is not a one-man show.CHIP usually require a longer ICU stay, so be prepared and backed up with a powerful ICU team.Do not lose hope, severely Impaired LVEF recovers with optimum revascularization.

Complete revascularization paid off with recovery of severely impaired LV (15% to 45%)
Complex PCI with IABP support

Good strategy! Congratulations on the great result!
