Virtual histology assessment of coronary atheroma influences treatment strategy in the young acute coronary syndrome patient.
Ormerod J., Johnston T., Ramcharitar S.
A 43-year-old woman having significant risk factors for ischaemic heart disease was admitted with an acute coronary syndrome (ACS). Coronary angiography revealed a non-flow limiting lesion in her right coronary artery with the rest of her arteries unremarkable. Risk stratification of the culprit lesion in the right coronary artery through intravascular ultrasound virtual histology demonstrated that the rupture plaque had less than 5% necrotic core with low vulnerability indices. This important finding suggested that the re-rupture risk was low so aggressive pharmacological treatment that can influence the plaque characteristics was instigated in preference to mechanical plaque sealing with a coronary stent. At a year of follow-up the patient was well and had no further events.
