Clinical Information

Patient initials or Identifier Number

ID- 6781-0

Relevant Clinical History and Physical Exam

Mr. X,  65 years old gentleman, normotensive, non-diabetic, smoker presented with complaints of central chest pain radiate to left arm. 
On examination, pulse was 80/minutes. Blood pressure was 130/80 mmHg. S1 and S2 were normal. Lung base was clear.
He also developed sudden cardiac arrest in hospital and was managed with prompt emergency treatment.
He gave a history of PCI to LCX and OM1 one month back.
He was labelled as NSTEMI with post PCI status and managed conservatively with LMWH.

Relevant Test Results Prior to Catheterization

Electrocardiogram showed anterior ischaemic changes.Echocardiogram showed anterior wall hypokinetic with LVEF 65 %.Serum Troponin Iwas 8.0 ng/Ml.HbA1c was5.6%.

Relevant Catheterization Findings

Check CAG through RFA revealsLeft Main: 95% stenosis in osteoproximal. LAD: Minor plaque in proximal part, type III vessel.LCX: Patent stent in mid LCX and OM1, dominant vessel. RCA: Normal and non dominant. Diagnosis: LM involvement with patent stent in LCX and OM1 Suggestion: PCI to left main.

Interventional Management

Procedural Step

EBU 3.5 ,6F guide catheter was used. Rinato and All star wires were crossed the lesion and parked in the distal part of the  LAD and LCX respectively. Pre dilatation was done by Maverick 2.5 mm X 15mm semi complaint balloon at 14 atm. IVUS images were taken before stenting. Synergy 3mm X 48 mm stent was deployed in the left main covering the proximal part of LAD at 16 atm. Post dilatation was done with NC Quantum 4mm X 12mm balloon at16 atm. After post dilatation, IVUS study was repeated. Procedure was uneventful.

Case Summary

Our patients had PCI to OM1 and LCX one month ago for unstable coronary disease. He was well and uneventful. After one month of PCI, admitted with cardiac arrest and Non STEMI. He had no or minimal lesion in osteo proximal part of the LM previously when he underwent PCI. Now his both stent had no stenosis with TIMI flow III, but LM had critical stenosis. We manage it with stenting to LM and proximal LAD with IVUS imaging. Is first PCI can induce lesion in LM?
