Introducción: El compromiso cardíaco es la principal causa de morbimortalidad en la amiloidosis, independientemente de la patogenia productora del amiloide subyacente. La amiloidosis por transtiretina (TTR) es una de las variantes más frecuentes, por lo cual el objetivo de este trabajo fue evaluar las características de una cohorte de pacientes con diagnóstico de cardiopatía amiloidótica por TTR (CA-TTR) Material y métodos: Se recabaron datos de los estudios basales,

Introduction: Children with surgically repaired esophageal atresia (EA) show esophageal dysmotility. Due to the performance of high-resolution manometry (HRM), three motility alteration patterns have been described, which allowed to know the segmental alterations. Objective: To describe the esophageal motility patterns found through HRM in teenagers with EA and to relate these with the associated esophageal pathology and its severity. Materials and Method: Ten teenagers were included with no history of esophageal blockage or dilations in the last six months, who were orally fed and asymptomatic. Through performance of HRM, we found surgical and endoscopic history, as well as of esophageal biopsies and pH monitoring. Results: We found the following patterns: aperistalsis, pressurization and distal contraction. 70% showed distal contraction, and 100% of esophageal endoscopies and biopsies were normal. 57% of the esophageal pH monitoring analyzed was pathologic. In the pressurization and aperistalsis groups, we observed severe esophagitis and requirement of Nissen antireflux procedure in 100% of the cases. Esophageal pH monitoring analyzed was 100% pathologic. Conclusion: We described the esophageal segmental alterations in teenagers with atresia by means of HRM. The distal contraction group showed better development, without severe esophagitis or requirement of antireflux procedure. Therefore,
