OBJECTIVE
Isolated ostial diagonal stenoses are very rare lesions in which percutaneous intervention could cause significant vessel compromise, and the long-term results have been reported in a few studies. This study sought the characteristics and long-term follow-up of the patients with isolated osteal diagonal stenosis regarding percutaneous coronary intervention and presence of angina.


METHODS
The study was an observational retrospective study conducted between January 2014 and December 2020. A total of 9769 patients who underwent coronary angiography were analyzed, and 87 patients had isolated diagonal stenosis. The patients were evaluated according to treatment modality and angina severity in long-term pattern.


RESULTS
Median follow-up time was 36 months. A total of 54 (83.1%) patients were followed up with only medical treatment, and 11 (16.9%) patients underwent revascularization in addition to medical treatment. The degree of stenosis of the diagonal artery was significantly
higher in the percutaneous coronary intervention group than medical group (P = 0.002) and the patients with wider reference diameter of diagonal artery complaint of more angina (P = 0.007). Class I angina was significantly higher in percutaneous coronary intervention group than medical and the patients with no angina were significantly higher in medical group than percutaneous coronary intervention group.


CONCLUSION
Percutaneous coronary intervention was mainly performed for diagonal arteries with a higher degree of stenosis; however, the patients who underwent percutaneous coronary intervention had angina more than 50% rates. Furthermore, the patients with ongoing angina had a larger diameter of the diagonal artery regardless of the type of treatment.
