Abstract

Objectives: Intravascular ultrasound (IVUS) plays a pivotal role in the current era of coronary interventions. We aimed to determine the prevalence of IVUS use and clinical outcomes of IVUS-guided percutaneous treatment of coronary arteries lesions in a South Asian country.

Material and methods: It is a retrospective observational study, a total of 134 consecutive patients having done IVUS, was enrolled from January 2013 to March 2020 at a single center.

Results: Out of 134 patients, 97 (72.4%) were male with a mean age of 63.1 ± 12.9 years. The prevalence of IVUS in our center was 3.0%. The most frequent comorbidity observed was dyslipidemia, n = 111 (82.8%). Non-ST-elevation myocardial infarction, n = 50 (37.3%), was the common mode of presentation. On coronary angiogram, the left main (LM) disease was found in n = 46 (34.3%), however, single-vessel disease, n = 51 (38.1%), was most commonly noted. IVUS utilization was higher in the left anterior descending, n = 94 (70.1%), followed by LM, n = 46 (34.3%). The LM mean minimal luminal area was 6.0 ± 2.6 mm2 and minimal luminal diameter was 4.53 mm ± 0.6 (mean). The coronary artery dissection was noted in n = 15 (11.2%). The mean duration of follow-up in our study was 40.3 ± 30.1 months. Major adverse cardiac events (MACEs) were recorded in n = 13 (9.7%), which included heart failure, n = 4 (3%). Cardiovascular death and target vessel revascularization occurred in n = 3 (2.2%).

Conclusion: IVUS results in a significant decrease in MACE. Our data might support the broader use of IVUS in both developed and in our part of the world.
