Percutaneous transluminal coronary angioplasty in Takayasu's arteritis

Left Main Snorkel Stent Thrombosis in Association With Takayasu Arteritis

Takayasu arteritis (TA) is a rare form of large vessel arteritis that predominantly affects the aorta and its major branches. This inflammation leads to thickening, fibrosis, and stenosis of the arterial walls, which may lead to thrombus formation. The resulting symptoms are typically due to ischemia of the end organs. Coronary artery involvement is uncommon and primarily affects the ostia of the arteries. Ostial involvement of the coronary arteries can have a dramatic course, including fatal outcomes. We present the case of a 16-year-old female with TA involving the ostium of the left main coronary artery, causing severe stenosis. A successful percutaneous coronary intervention was performed on the left main artery with snorkel stent placement, which was complicated by cardiac arrest seven months later due to complete thrombosis of the proximal opening of the protruding stent.

Three-year outcome with drug-coated balloon percutaneous coronary intervention in coronary Takayasu arteritis: A case review

We describe the first long-term follow-up of a young patient with active Takayasu arteritis who presented with an acute coronary syndrome, treated endovascularly with percutaneous coronary intervention without stenting. A drug-coated balloon was used with high-resolution coronary imaging guidance in the form of optical coherence tomography on a critical ostial left anterior descending coronary artery lesion. A repeat procedure was undertaken after 4 months confirming a durable coronary angioplasty result and the patient remained symptom-free beyond 3 years. Coronary stenting in this population is associated with early and aggressive stent failure. Hence, this is an innovative approach. We believe that the stent, regardless of whether it is first, second or subsequent generation, leaves a permanent foreign body within the vasculature that becomes the seed for inflammatory reactions, resulting in recurrent in-stent restenotic fibrosis irrespective of concurrent immunotherapy or the degree of disease activity.

Pivotal role of cardiac magnetic resonance imaging in a new case of Takayasu arteritis

Takayasu arteritis (TA), also known as the pulseless disease, is a form of vasculitis of unknown cause that chiefly affects the aorta and its major branches, most frequently in young women. The earliest detectable abnormality in TA is a thickening of the vessel wall, but diffuse aortic wall calcification is very rare and is a late manifestation. Besides, the involvement of the coronary arteries is not a common finding in TA and frequently involves the right coronary artery (RCA). Multi-modality imaging has a fundamental role in the diagnosis of vasculitis and its complications. In this report, we want to present an unusual case with TA, diffuse aortic wall calcification and left main coronary artery ostial lesion, which is a rare combination.

The Journey of an Indian Pediatric Cardiologist : Dr. K. C. Chaudhuri Lifetime Achievement Award/Oration at AIIMS, New Delhi, September 2017

The life journey of an Indian pediatric cardiologist, who bestowed considerable attention to the development of new knowledge and train/teach physicians around the world while providing care of patients with heart disease over a 45-y period, is reviewed. This appraisal focuses particular attention on the scientific contributions to the literature. These include spontaneous closure of physiologically advantageous ventricular septal defects, various issues related to a congenital heart defect namely, tricuspid atresia and transcatheter and, interventional pediatric cardiac procedures.

Takayasu's Arteritis: Current Status of Angioplasty and Stenting

Takayasu's arteritis is a chronic inflammatory disease characterized by stenotic occlusive lesions of the aorta and its major branches. The medical management of such lesions is far from satisfactory and surgical treatment is associated with high morbidity and mortality. Angioplasty with or without stenting has emerged as the treatment of choice for such lesions. Angioplasty and stenting of various vessels in Takayasu's arteritis are reviewed, highlighting the advantage of stents in reducing the rate of restenosis in chronically occluded or diffusely diseased vessels.

Stenosis of the main stem of the left coronary artery in a teenager with Takayasu's arteritis

Coronary arterial involvement is rare in Takayasu's arteritis. We describe successful coronary arterial bypass grafting in a 15 year teenager with Takayasu's arteritis and unstable angina because of stenosis of the main stem of the left coronary artery.

Coronary involvement in Takayasu's arteritis

Coronary involvement may appear in up to a third of patients with Takayasu's arteritis. This affliction may have a dominant impact on the clinical manifestations of the patient. Occlusion of the ostia of the left main coronary artery and of proximal segments of the coronary arteries is the most frequent finding of the coronary vasculature in patients with Takayasu's arteritis. Beyond the vasculitic process enhanced atherosclerosis has a significant and detrimental impact on the disease development. Revascularizations are often unsuccessful particularly when the inflammatory disease is not under satisfactory control. New techniques have been developed in order to use vessels that have not been damaged by the disease as grafts.

Isolated bilateral coronary ostial stenosis—An uncommon presentation of aortoarteritis

Aortoarteritis presenting with isolated bilateral coronary artery ostial stenosis is a serious but rare condition. This letter emphasizes on a very atypical presentation of aortoarteritis and also distinct but unusual form of angiographic findings involving total occlusion of left main coronary artery from the ostium and tight ostial right coronary artery stenosis that had a fulminant disease course.

Takayasu's arteritis: A case report and a brief review of the literature

Takayasu’s arteritis primarily affects young women. The current case report focuses on a Caucasian middle-aged woman who complained of weakness, malaise, and fatigue for as many as 19 years. Delayed diagnosis and lack of specific treatment could explain the extent and the clinical severity of the disease at time of hospital admission. Angiography showed focal narrowings of the abdominal and thoracic aorta and occlusion of both the subclavian arteries, of the right coronary artery and severe stenosis of the first marginal obtuse. Takayasu’s arteritis is not limited to women of Japanese origin but is present worldwide. Early diagnosis and treatment is warranted. Outcome appears to be favorable when the disease is quiescent.

Takayasu's arteritis: management of left main stem stenosis

Takayasu arteritis is a chronic vasculitis involving the aorta and its main branches, the pulmonary arteries, and the coronary tree, and needs to be considered in a young patient with angina, in particular when pulses are absent. This case illustrates the limitations of exercise testing in diagnosing the extent of coronary artery disease and the risks associated with coronary angiography in patients with inflammatory disease in the left main stem coronary artery. It also highlights the novel use of non-invasive scanning with positron emission tomography using 18-fluorodeoxyglucose in assessing remission from this disease. Revascularisation was performed with percutaneous transluminal coronary angioplasty and stenting as an emergency procedure, but treatment of the restenosis with directional atherectomy was based on a review of the available literature. The lymphocytic alveolitis seen in this patient has not been previously described in Takayasu's disease.

[Takayasu's disease in Morocco. Report of 47 cases]

PURPOSE

Takayasu's disease is a chronic inflammatory arteritis involving large vessels in young women. We studied Moroccan patients to evaluate clinical, biological, radiological and evolution features of this disease in our country.

METHODS

Forty-seven patients with Takayasu's arteritis were studied retrospectively between 1988 et 1999.

RESULTS

In our series involvement of the aortic arch and its branches was more frequent than the abdominal aorta and its branches. Stenotic lesions of renal arteries were rare. Ultrasound was useful in the diagnosis and the monitoring of the disease. Treatment with glucocorticoids gave good results, with improvement in half of the patients and remission with stabilisation in 40% of cases. Tuberculosis occurred in 8.5% of patients.

CONCLUSION

The use of ultrasound and computed tomography angiography is helpful for the diagnosis and monitoring of the disease progression. Glucocorticoids help to induce long remission in about 80% of treated patients. We don't find any relationship between Takayasu's arteritis and tuberculosis.

[Cardiac manifestations of Takayasu's arteritis: apropos of 5 cases]

PURPOSE

Cardiac manifestations of Takayasu's arteritis are rarely reported in the literature. However, these symptoms are not rare and when they do occur, they determine the disease prognosis. Due to its frequency, its severe nature, and even sometimes diagnosis failure, high blood pressure is the major cause of cardiac manifestations. More specific cardiac manifestations of either coronary, valvular, or more rarely, myocardial origin may also occur.

METHODS

Analysis of five cases of Takayasu's arteritis and a literature review allowed evaluation of both the frequency and characteristics of this disease.

RESULTS

Four female and one male patients presenting with symptoms of Takayasu's arteritis, according to Fiessinger's score, were evaluated. Diagnosis of cardiac disease was based on clinical, echocardiographic and angiographic criteria. Four patients had related high blood pressure. Valvular manifestations were present in all the patients. They included mitral insufficiency (1 case); aortic insufficiency (2 cases), and both mitral and aortic insufficiency (2 cases). Two patients showed clinical manifestations of a myocardiac disease, and another showed coronary signs. Treatment did not involve surgery, including only antihypertensive drugs, nitrites, and diuretics associated with digitalin in case of cardiac failure. The disease outcome, including a 5-18 year follow-up, involved symptom decrease in all the patients.

CONCLUSION

Despite the rarity of cardiac manifestations in patients suffering from Takayasu's arteritis, symptoms of this disease should always be investigated, as these manifestations alter the prognosis. Aortic insufficiency is the most frequently encountered cardiac manifestation.
