Admitting Diagnoses:
- Chest pain on exertion
- Stable exertional angina pectoris

Hospital Course:
A 72-year-old man with multiple coronary risk factors, including hypertension, dyslipidemia, and diabetes mellitus, was admitted to our hospital with chest pain on exertion. Transthoracic echocardiography revealed mild left ventricular hypertrophy and no segmental wall motion abnormality. Coronary computed tomography angiography revealed significant stenosis in the distal left main trunk (LMT), ostial left anterior descending artery (LAD), and ostial left circumflex artery (LCX). The patient refused a surgical approach and underwent percutaneous coronary intervention (PCI) using a simultaneous jailed balloon and jailed Corsair technique for the left main trifurcation lesion. The post-procedure course was uneventful, and the patient's angina symptoms disappeared. Follow-up coronary angiography was performed two weeks after the procedure, which revealed no signs of restenosis in both the main vessel and side branches.
