Williams?Beuren Syndrome with Pseudoaneurysm of Aortic Arch and Infective Vegetations for Modified Broms Procedure: Anesthetic Concerns & Echocardiographic Illustrations. International Journal of Medical Research & Health Sciences. 2023 Mar; 26(1): 94-960974-51810971-9784http://imsear.searo.who.int/handle/123456789/219279Williams?Beuren syndrome is a rare genetic malformation with predilection for supravalvular aortic stenosis. Apart from cardiovascular malformation, hypocalcemia, developmental delay, and elfin facies, challenging airway make perioperative management more eventful. Association of infective endocarditis within the aortic arch and pseudoaneurysm formation is infrequent. We, hereby report a case of pseudoaneurysm formation and infective vegetation within the aortic arch in a patient with Williams syndrome and the role of transthoracic echocardiography in its perioperative management.Echocardiographyinfective endocarditismodified broms procedurepseudoaneurysm of aortic archsupravalvular aortic stenosiswilliams?beuren syndromeWilliams?Beuren Syndrome with Pseudoaneurysm of Aortic Arch and Infective Vegetations for Modified Broms Procedure: Anesthetic Concerns & Echocardiographic IllustrationsJournal ArticleIndiaDepartment of Cardiac Anaesthesia, Cardiothoracic Centre, CNC, All India Institute of Medical Sciences, New Delhi, Ansari Nagar, New Delhi, India
