I worked closely with Dr Larry Lands, Dr Thérèse Perreault and Dr Guilherme Sant’anna on a review of the evaluation of BPD patients with PH. Following that, I spent a year of post-doctoral training in the echocardiography laboratory at Lucile Packard Children’s Hospital at Stanford University. At Stanford, I worked under the supervision of Dr Theresa Tacy, pediatric cardiologist and chief of the echocardiography laboratory, as well as Dr Shazia Bhombal, neonatologist and cardiologist. I studied patients with congenital diaphragmatic hernia (with supervision of Dr Krisa Van Meurs, CDH/ECMO specialist), and patients with hypoplastic left heart syndrome and tricuspid atresia / pulmonary atresia with intact ventricular septum. In these patients, I analysed early echocardiography markers using deformation analysis of their ventricular function (strain analysis). As well, I worked with Dr Jeffrey Feinstein, specialist in pulmonary hypertension, on the population of bronchopulmonary dysplasia patients with PH at Stanford University. Finally, I worked with Dr Valerie Chock, neonatologist, specialist in near infrared spectroscopy, to analyse the renal and cerebral NIRS behaviors of single ventricular patients in the immediate post-natal period. At the Montreal Children’s Hospital, I am developing a platform on hemodynamic research. Demographic, clinical and echocardiography data will be collected prospectively on different population of newborns. My research focuses on BPD patients with pulmonary hypertension, CDH patients, and congenital cardiac defect patients. I have a particular interest in early neonatal markers of outcomes and am hoping to work towards improving management of these high risk patients. My research targets these populations within the neonatal unit, during their pediatric growth, and within the adult world, as a continuum. I highly encourage fellows to develop their interest in doing research in hemodynamic assessment of these newborns. I have also completed (2017-2020) a MSc in Clinical Epidemiology at McGill University in order to become self-sufficient in bio-statistical analysis.

Bio - Juin 2025: 

Le Dr Gabriel Altit a obtenu son diplôme de médecine à l’Université McGill avant de compléter sa résidence en pédiatrie puis sa surspécialité en néonatologie à l’Université de Montréal. Il est ensuite revenu au Centre universitaire de santé McGill (Hôpital de Montréal pour enfants) pour une formation avancée en échocardiographie ciblée, puis a poursuivi un fellowship de recherche post-doctorale au Pediatric ECHO Lab de l’Université Stanford. Parallèlement, il a terminé une maîtrise en épidémiologie à McGill (2017-2020). Nommé néonatologiste au sein de l’Université McGill et de l’Hôpital de Montréal pour enfants en octobre 2017, il a depuis bâti un programme de recherche translationnelle en hémodynamie néonatale. À titre de clinicien-chercheur (FRQS Junior 1) à l’IR-CUSM, il a fondé le NeoCardioLab (www.neocardiolab.com), une plateforme reconnue à l’international offrant ressources pédagogiques, site Web et application mobile (iPhone, iPad et Android) utilisés quotidiennement par la communauté TnECHO. Ses travaux, soutenus notamment par l’American Thoracic Society, la Fondation de la Recherche Pédiatrique, les IRSC, le Grand défi Pierre Lavoie et la Fondation Pour Enfants Seulement, portent sur la physiologie cardiovasculaire du nouveau-né, la POCUS cardiaque et l’imagerie avancée. En 2020, il a lancé et dirige le programme de fellowship en hémodynamie néonatale de McGill, seul programme accrédité par le Collège royal des médecins et chirurgiens du Canada au Québec. Il est professeur agrégé au Département de pédiatrie de l’Université McGill. Le Dr Altit siège au Comité Fœtus et Nouveau-Né de la Société canadienne de pédiatrie, co-rédige plusieurs énoncés de principes nationaux et agit comme expert-conseil auprès de l’INESSS sur l’hyperbilirubinémie néonatale.

Bio – June 2025: 

Dr. Gabriel Altit earned his medical degree from McGill University before completing his residency in pediatrics and subspecialty training in neonatology at the Université de Montréal. He returned to the McGill University Health Centre (Montreal Children’s Hospital) for advanced training in targeted neonatal echocardiography, followed by a postdoctoral research fellowship at the Pediatric ECHO Lab at Stanford University. In parallel, he completed a Master’s in Epidemiology at McGill (2017–2020). Appointed as a neonatologist at McGill University and the Montreal Children’s Hospital in October 2017, he has since built a translational research program in neonatal hemodynamics. As a clinician-scientist (FRQS Junior 1) at the RI-MUHC, he founded NeoCardioLab (www.neocardiolab.com), an internationally recognized platform offering educational resources, a website, and a mobile app (available on iPhone, iPad, and Android), used daily by the global TnECHO community. His research, supported by the American Thoracic Society, the Pediatric Research Foundation, CIHR, the Grand défi Pierre Lavoie, and the Fondation Pour Enfants Seulement, focuses on neonatal cardiovascular physiology, cardiac POCUS, and advanced imaging. In 2020, he launched and currently directs McGill’s fellowship program in neonatal hemodynamics, the only Royal College–accredited program of its kind in Quebec. Dr. Altit is an Associate Professor in the Department of Pediatrics at McGill University. He serves on the Fetus and Newborn Committee of the Canadian Paediatric Society, co-authors several national position statements, and acts as an expert advisor to INESSS on neonatal hyperbilirubinemia.
