Clinical Information

Patient initials or Identifier Number

AFAF

Relevant Clinical History and Physical Exam

30-year-old lady with background history of smoking and combine oral contraceptive use presented with sudden onset typical chest pain at 3 am with worsening symptoms at 11.30 am. ECG showed 1mm ST elevation at AVL with Troponin raised 160 ng/L at presentation to hospital 12.30 pm. Hemodynamically stable.

Relevant Test Results Prior to Catheterization

Proceeded directly to cardiac catheterization

Relevant Catheterization Findings

Noted filling defect at proximal left anterior descending artery extending into left main coronary arteryIVUS done showed thrombus laden lesion with dissection from mid left main coronary artery to proximal left anterior descending artery

Interventional Management

Procedural Step

In view of left main coronary artery involvement and patient in persistent angina, decided to proceed with coronary intervention. Left anterior descending and left circumflex artery wired. Thrombus aspiration done with Export advance catheter. Proceeded with direct stenting from left main coronary artery till proximal left anterior descending with Resolute Onyx 3.5/38mm. Post stenting noted thrombus embolization to distal artery, no flow to septal branch. Septal wired with sion blue and dilated with Sapphire II Pro 1.5/10mm. Thrombus aspiration with Export catheter done. Intracoronary aggrastat given. Able to restore flow to septal. Stent post dilated with NC Emerge 4.0/15mm. Stent apposition checked with IVUS and further optimized with NC Emerge 4.5/12mm to proximal stent at left main. Final IVUS done, good stent apposition. Final angiographic shot taken and result accepted.

Case Summary

This young lady presented with STEMI due to spontaneous coronary artery dissection. Clinical decision for angioplasty made in view of on-going chest pain and dissection involving left main coronary artery which is a high risk area. Troponin T peaked at 2320 pg/ml. Post procedure, she remained angina free and was discharged well.
