    A Shunt From the Brain: Left Internal Carotid Artery Arising From the Left Pulmonary Artery in Tetralogy of Fallot
    (ANNALS OF THORACIC SURGERY, 2015) Idhrees, AM; Mathew, T; Menon, S; Dharan, BS; Jayakumar, K
    Origin of a common carotid artery from a pulmonary artery is extremely rare, but isolated origin of an internal carotid artery from a pulmonary artery with intracardiac anomaly has not been reported before. We report a case of the left internal carotid artery arising from the left pulmonary artery in a case of tetralogy of Fallot. The possible embryologic mechanism and the surgical management of this unique lesion are described. (C) 2015 by The Society of Thoracic Surgeons

    Left ventricular regression after balloon atrial septostomy in d-transposition of the great arteries
    (EUROPEAN JOURNAL OF CARDIO-THORACIC SURGERY, 2016) Gopalakrishnan, A; Sasidharan, B; Krishnamoorthy, KM; Sivasubramonian, S; Dharan, BS; Mathew, T; Titus, T; Valaparambil, A; Tharakan, J
    OBJECTIVES: Balloon atrial septostomy (BAS) is an effective palliative procedure in children with transposition of the great arteries and poor intercirculatory mixing. While the subpulmonary left ventricle (LV) is known to regress with time in these newborns due to the declining afterload, it has not been studied how it behaves following BAS and a consequent decrease in preload. The study was designed to examine the effects of BAS on the LV in infants with simple d-transposition of the great arteries by serial 2D echocardiographic monitoring. METHODS: This was a prospective echocardiographic follow-up study of all consecutive children with simple d-transposition of the great arteries who underwent BAS for restrictive interatrial communication and oxygen saturation below 75% between January 2014 and June 2015. Left ventricular mass estimation was done by M-mode transthoracic echocardiography before balloon septostomy and serially on follow-up till surgery. RESULTS: The median age of the 25 children studied was 4 days (1-95 days) when they underwent BAS. Twenty patients underwent arterial switch operation at a mean of 9 days from balloon septostomy. The mean baseline left ventricular mass was 47.9 g/m(2), which decreased to 38.5, 36.2, 32.1, 32.4, 25.7 and 25.2 g/m(2) on Days 1, 3, 6, 9, 12 and 15, respectively. The left ventricular mass decreased by 1.5 g/m(2) every day during the first 2 weeks following balloon septostomy adjusted for the age of the child in days. Children who underwent BAS beyond 3 weeks of life had faster LV regression than those who underwent the procedure earlier (unstandardized regression coefficient beta 0.892, P < 0.001). CONCLUSIONS: BAS is associated with accelerated regression of the LV in infants with simple d-transposition of the great arteries in the first 2 weeks after the procedure. Regression of the LV is faster in children who underwent BAS after 3 weeks of age.

    Multiple Muscular Ventricular Septal Defects: Use of Fluorescein Dye to Identify Residual Defects
    (ANNALS OF THORACIC SURGERY, 2014) Mathew, T; Kundan, S; Abdulsamad, MI; Menon, S; Dharan, BS; Jayakumar, K
    Multiple muscular ventricular septal defects remain a challenge for the congenital heart surgeon. The optimal strategy for an infant or neonate with multiple muscular ventricular septal defects is still unclear. Perioperative identification and secure closure of these defects pose significant difficulties. We describe a novel technique of using fluorescein dye to identify small muscular ventricular septal defects. (C) 2014 by The Society of Thoracic Surgeons
