Hello,
With the question “Can IVUS ultrasound assess the risk of coronary artery stenosis? ", the doctor would like to answer as follows:
Coronary angiogram results up to 95% stenosis is very severe (>90%), in this case, coronary stenting intervention is indicated in accordance with the guidelines of the Heart Association Vietnam and Cardiovascular Associations around the world. However, the choice of intervention (coronary stenting), or coronary artery bypass grafting (CABG) surgery to treat coronary artery disease will depend on the damage of the whole coronary system (ie when evaluated in both patients). 3 branches and describe the location of the lesion). In this case, the treating doctor will fully discuss with you when there is an agreement between the interventional doctor and the surgeon. So in summary: Your grandmother has indicated coronary revascularization and revascularization because of severe stenosis on coronary angiography.
IVUS is a device used for intravascular ultrasound, it is a means to assist the interventional doctor in: Assessing the extent of damage (narrow location, degree of stenosis, nature of atherosclerotic plaque), IVUS is also used to evaluate outcomes after stenting. In other words, IVUS is a useful device, an important tool to help doctors get an accurate conclusion about coronary lesions (in terms of imaging), with optimal intervention strategies. especially when lesions are in difficult locations (branching of coronary arteries), help doctors optimize intervention results (select stents of appropriate size, suitable length for lesions, improve pressure good wall of the stent to limit restenosis in the stent after intervention).
If you still have questions about whether the IVUS ultrasound method can assess the risk of coronary artery stenosis, you can go to a hospital of Vinmec Health System for further examination and advice. Thank you for trusting and sending questions to Vinmec. Wish you a lot of health.
