This book was released on 2011 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: L'échocardiographie (ETT) a été validée pour le dépistage de l'hypertension pulmonaire (HTP). Sa place dans le diagnostic et le suivi de l'HTP reste toutefois mal définie. Plusieurs études récentes mettent en doute la pertinence clinique de l'estimation de la pression artérielle pulmonaire systolique (PAPs) par ETT. Objectif. Les but de l'étude sont d'analyser la corrélation entre les mesures, à l'ETT et au cathétérisme artériel pulmonaire, de PAPs et de débit cardiaque, et de définir des indices échocardiographiques de dysfonction ventriculaire droite dans l'HTP. Méthodes: Il s'agit d'une étude prospective monocentrique, dans laquelle les CAP et ETT ont été réalisés pour chaque patient dans un intervalle de moins d'une heure. Résultats: Cinquante neuf patients ont été inclus dans l'étude. Cent vingt neuf évaluations hémodynamiques ont été réalisées par CAP et ETT. Pour la mesure de la PAPs par les 2 techniques, le biais était de 4,48 mmHg et les limites d'aggrément 95% étaient de -25,11 et 34,09 mmHg, avec une corrélation de r=0,62 (p0,001). Nous avons montré une pertinence clinique satisfaisante de l'ETT pour le diagnostic d'HTP. La mesure d'une vitesse maximale du flux d'insuffisance tricuspide 2.94 m/s permet de prédire la présence d'une HTP avec une sensibilité et une spécificité de 86% et 93% respectivement (AUC=0,924). Le calcul de la PAP moyenne à partir de la PAPs ETT permet de faire le diagnostic d'HTP avec une sensibilité et une spécificité de 84% et 93% respectivement (AUC=0,925). Nous avons montré qu'une valeur de l'excursion systolique du plan de l'anneau tricuspide (TAPSE) 17 mm permet de prédire la présence d'une HTP avec une sensibilité et une spécificité de 58% et 93% respectivement (AUC=0,789) et est associé dans 86% à une dyspnée de stade III ou IV. Nous avons déterminé qu'une valeur de rapport des surfaces télédiastoliques des ventricules droit et gauche (STDVD/STDVG) 0,78 est associée au diagnostic d'HTP avec une sensibilité et une spécificité de 66% et 93% respectivement (AUC=0,828) et à une dyspnée de stade III ou IV dans 85% des cas. Nous avons montré que la mesure de la vélocité de l'onde S tricuspidienne ne permettait pas de prédire la présence d'une HTP (p=0.8 et AUC=0.53). Nous avons mis en évidence une absence de corrélation entre les mesures de débits cardiaque à l'ETT et au CAP (biais de -0,54 L/min, limites d'aggrément 95% entre 3,55 et -4,64, r=0.2, p=0,002). Nous n'avons pas retrouvé de corrélation entre l'évaluation ETT de la PAPO, à l'aide de l'analyse en Doppler pulsé du flux mitral et du Doppler tissulaire mitral, et sa mesure invasive par le CAP (r=0,04, p=0,16). Neuf patients ont bénéficié d'une réévaluation dans le cadre de leur suivi d'HTP. Nous avons montré une bonne corrélation entre les mesures de PAPs et de débit cardiaque à l'ETT et au CAP chez ces patients mais ces résultats restent à confirmer sur un effectif plus important. Conclusion: Nos résultats ont permis de confirmer l'utilité de l'ETT pour le dépistage de l'HTP. Elle permet d'étudier des paramètres de la fonction ventriculaire droite comme le TAPSE et le rapport STDVD/STDVG, prédictifs d'une HTP et associé à une dyspnée de stade III ou IV. Ces indices pourraient être utilisés dans l'algorithme de prise en charge thérapeutique de ces patients. L'utilité de l'ETT pour le suivi des patients atteints d'HTP reste à confirmer.
Download or read book Pr cision diagnostique et valeur pronostique de l chocardiographie dans le d pistage et le suivi de l hypertension pulmonaire written by Leïla Potton and published by . This book was released on 2011 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: L’hypertension pulmonaire (HTP) est définie par une pression artérielle pulmonaire moyenne (PAPm) > 25 mmHg au cathétérisme cardiaque (KTC). L’échocardiographie transthoracique (ETT) est en première ligne pour le dépistage de l’HTP. Nous avons cherché à déterminer la précision de l’ETT dans l’estimation des pressions pulmonaires, et à évaluer l’apport des marqueurs de dysfonction VD dans le dépistage de l’HTP. Notre objectif secondaire était de déterminer la valeur pronostique de ces marqueurs. La corrélation entre ETT / KTC était de 0,61(p 0,001), mais la concordance ETT / KTC selon Bland et Altman était imparfaite, avec des limites d’agrément larges de +40 à -36 mmHg. En outre, les PAPs estimées par ETT différaient de la mesure invasive de 10 mmHg dans 53% des cas. En termes de dépistage, la valeur seuil de PAPs 50 mmHg offrait la meilleure performance diagnostique par rapport à la méthode de référence invasive. Une stratégie séquentielle basée sur la mesure de la PAPs et la mesure de l’onde St(dti) en cas de PAPs

Download or read book Hypoxic Respiratory Failure in the Newborn written by Shyamala Dakshinamurti and published by CRC Press. This book was released on 2021-10-29 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: We have all been hypoxic. Fetal tolerance for intrauterine hypoxia arises from evolutionarily conserved physiological mechanisms, the antecedents of which can be learned from diving mammals or species at high altitudes. Understanding fetal hypoxia leads to understanding the huge physiological shifts of neonatal transition and the dangers of perinatal hypoxia. This comprehensive volume of topical review articles by expert authors addresses the origins of hypoxia tolerance, the impact of oxygen on circulatory transition at birth, and the biochemistry of hypoxia in the pulmonary circuit, as well as the classification, diagnosis, and clinical management of hypoxic respiratory failure and persistent pulmonary hypertension in the term neonate. The goal of Hypoxic Respiratory Failure in the Newborn is to connect our understanding of hypoxia from animals in extreme environments, with how the human fetus handles its hypoxic environment; and why the human newborn suddenly cannot. The book will educate health care professionals on how to care for newborns with hypoxic respiratory failure, including the use of up-to-date diagnostic tools and therapies. It also highlights areas of controversy and ongoing research in hypoxic respiratory failure and pulmonary hypertension of the newborn, including challenging case studies. Key Features Explores evolutionary context and comparative physiology of hypoxia tolerance in the fetus and neonate, from basic research to clinical scenarios Provides guidance to trainees, physicians, and allied health professionals engaged in NICU care; pediatricians, cardiologists, pulmonologists, anesthesiologists, neonatologists, and physiologists to effectively manage infants in hypoxic respiratory failure Includes case scenarios emphasizing current diagnostic and therapeutic controversies and algorithmic approaches to decipher difficult clinical cases
