OBJECTIVE: We sought to describe the prevalence, management strategies and evaluate the prognosis of patients with iatrogenic catheter-induced ostial coronary artery dissection (ICOCAD).
BACKGROUND: ICOCAD is a rare but potentially devastating complication of cardiac catheterisation. The clinical manifestations of ICOCAD vary from asymptomatic angiographic findings to abrupt vessel closure leading to myocardial infarction and death.
METHODS: 55,968 patients who underwent coronary angiography over a 10-year period were screened for ICOCAD as defined by the National Heart, Lung, and Blood Institute. The management and all-cause mortality were retrieved from local and national databases.
RESULTS: The overall prevalence of ICOCAD was 0.09% (51/55,968 patients). Guide catheters accounted for 75% (n = 37) of cases. Half of the ICOCAD cases involved the right coronary artery while the remaining were related to left main stem (23/51; 45%) and left internal mammary artery (2/51; 4%). Two-thirds of ICOCAD were high grade (type D, E, and F). The majority of cases were type F dissections (n = 18; 66%), of which two third occurred in females in their 60s. The majority of ICOCAD patients (42/51; 82%) were treated with percutaneous coronary intervention while the remaining underwent coronary artery bypass grafting (3/51; 6%) or managed conservatively (6/51; 12%). Three deaths occurred during the index admission while 48/51 patients (94.1%) were safely discharged without further mortality over a median follow-up of 3.6 years.
CONCLUSIONS: ICOCAD is a rare but life-threatening complication of coronary angiography. Timely recognition and prompt bailout PCI is a safe option for majority of patients with good clinical outcomes.
