Clinical Information
Relevant Clinical History and Physical Exam
Thai male 69 years, Risk Hypertension, Dyslipidemia presented with chest pain 2 hours prior to admission. Blood pressure 104/62 mmHg Heart rate 76 bpm. Heart regular, fine crepitation both lower lungs. EKG showed Normal sinus rhythm, 84 bpm, ST elevation II, III, AVF, diffused ST depression V2-V6. Echocardiogram showed LVEF 42%, Global wall Hypokinesia, no significant valvular heart disease. Troponin T was positive 10,400 pg/ml. Chest x-ray showed cardiomegaly, increase pulmonary vasculature


Relevant Test Results Prior to Catheterization
EKG showed Normal sinus rhythm, 84 bpm, ST elevation II, III, AVF, diffused ST depression V2-V6. Echocardiogram showed LVEF 42%, Global wall Hypokinesia, no significant valvular heart disease. Troponin T was positive 10,400 pg/ml. Chest x-ray showed cardiomegaly, increase pulmonary vasculature.


Relevant Catheterization Findings
Access: Right radial via 6Fr sheath.- LM: non significant stenosis- LAD: Subtotal occlusion mid-LAD, CTO mid to distal LAD.- LCx: CTO mid-LCx with collateral from OM1.- RCA: Total occlusion proximal RCA with collateral from LCA.






Interventional Management
Procedural Step
PCI to culprit RCA:Access right radial.Guiding Catheter: 5 Fr Ikari guiding catheterStenting proximal to mid RCA with Resolute integrity 2.5 x 22 mm upto 12 atm.
The patient still had chest pain then stage PCI to CTO LAD with Right distal radial approach (DRA).
Staged PCI to CTO LAD:Access right distal radial access (DRA) in the anatomical snuffbox.Guiding Catheter: 5 Fr Ikari guiding catheterSion with finecross pass to LAD then change to Fielder XT pass through CTO LAD.Tip injection revealed true lumen wiring .Semi-compliant balloon 2.0 x 15 mm inflated p-dLAD upto 14 atm.Xience ProA 2.5 x 38 mm deployed mid to distal LAD upto 12 atm. Resolute integrity 2.75 x 30 mm deployed proximal to mid LAD upto 12 atm. Acceptable angiographic result.

Case Summary
The distal radial approach (DRA) is a feasible and safe alterative for complex PCI.Using a 5 Fr guiding cather is effective for complex lesion like CTOs and reduces vascular complications.This case report demonstrates the a complex CTO LAD can be successfully treated with a minimalist approach using right DRA and a 5 Fr Ikari guiding catheter.percutaneous coronary intervention (PCI) for chronic total occlusion (CTO) using a 5 Fr radial Ikari guide catheter can be successful in selected cases.
