Left main trunk ostial stenosis and aortic incompetence in Takayasu's arteritis

Takayasu's arteritis presenting as acute myocardial infarction: case series and review of literature

This series describes three adolescent females who presented with chest pain and ventricular dysfunction related to acute coronary ischemia secondary to Takayasu's arteritis with varied courses of disease progression leading to a diverse range of therapies including cardiac transplantation. While Takayasu's arteritis is rare in childhood, it should be strongly considered in any adolescent female presenting with systemic inflammation and chest pain consistent with myocardial infarction. A high index of suspicion can lead to early detection and aggressive management of the underlying vasculitis reducing associated morbidity and mortality. The purpose of this report is to describe the challenges in the clinical diagnosis and management of Takayasu's arteritis with myocardial infarction. We also seek to enhance awareness about unique presentations of Takayasu's arteritis within the paediatric community.

Coronary artery bypass for Takayasu's arteritis involving the aortic root in a child

The patient was a 12-year-old female who presented with angina pectoris, aortic root dilatation, and aortic regurgitation (AR) caused by Takayasu's arteritis (TA). After the management of systemic inflammation, she underwent off-pump coronary artery bypass with the radial artery (RA), which extended from the left axillary artery to the left descending coronary artery, via left mini-thoracotomy. Postoperative angiography revealed the growth of the RA graft. The patient is well 4 years after surgery without progression of AR. Off-pump coronary artery bypass is a palliative therapy. Moreover, it could be a feasible option in a child with TA involving the aortic root.

Severe Aortic Regurgitation and Left Main Coronary Artery Ostial Stenosis in a 21-Year-Old Woman: What's Going On?

•

TA is a progressive, relapsing large-vessel vasculitis.

•

TA usually affects the aorta and its major branches.

•

TA can cause LMCA or ostial lesions in young adults.

•

Involvement of the aorta in TA can cause AR of varying degrees.

•

Surgical rather than percutaneous revascularization produces better results in TA.

Coronary artery involvements in Takayasu arteritis: systematic review of reports

Coronary artery involvements in patients with Takayasu arteritis (TA) have not been sufficiently described. By comprehensive retrieval of the pertinent literature published in the past two decades, 59 reports including 141 patients were recruited into this study. In TA patients with coronary artery involvements, the right coronary artery was the most commonly affected. Stenosis was the most common coronary artery lesion, and the coronary ostium was the most commonly affected coronary segment. Acute myocardial infarction was diagnosed in 17 (12.1%) patients of this cohort. Patients receiving surgical treatment showed a higher recovery rate than interventionally treated patients. Interventional therapy was associated with a higher reintervention rate than surgical treatment. The inflammation condition in TA patients can lead to in-stent restenosis and warrant reinterventions. Surgical treatment is a preferable treatment of choice over interventional therapy for the coronary artery lesions of TA patients.
