Due to lack of data regarding this procedure in Vietnam we conducted this study to gather additional data on CTO intervention in diverse patient populations. Objectives Determine the success rate and the variables associated with procedural failure of percutaneous coronary intervention for chronic total occlusion lesions Methods We conducted a observational trial on patients undergoing percutaneous coronary intervention for chronic total occlusion lesions at University Medical Center Ho Chi Minh City from April 2017 to June 2019. Results The mean age of the study participants was and of them were male. Co-morbidities were hypertension old myocardial infarction prior percutaneous coronary intervention diabetes mellitus chronic kidney disease . Acute coronary syndrome was diagnosed in of patients. SYNTAX I average score was . The procedural success rate was and the characteristics associated with procedural failure were BMI gt 25kg m2 high J-CTO score J-CTO score 3 ambiguous proximal cap turtuos vessel cacified vessel and retrograde CTO approach and without use of intravascular ultrasound. Conclusion Our study found that the successful rate of percutaneous coronary intervention for chronic total occlusion lesion is high and variables .
