We report a 13-month-old male with right isomerism, single ventricle physiology, and asplenia who presented with postprandial vomiting. Computed tomography revealed a PDPV anterior to the pylorus, and upper gastrointestinal contrast study confirmed mesentericoaxial gastric volvulus. Surgery consisted of gastric derotation, ante-PDPV pyloroduodenostomy, and anterior gastropexy. The patient recovered uneventfully and remained asymptomatic at 9-month follow-up. To our knowledge, this is the first report of PDPV with right isomerism complicated by gastric volvulus. Absent gastric stabilizing ligaments in asplenia, combined with PDPV-related obstruction, may predispose to volvulus. Multimodal imaging and individualized surgical management are essential in this rare setting.<\/jats:p>","DOI":"10.1093\/jscr\/rjag483","type":"journal-article","created":{"date-parts":[[2026,6,3]],"date-time":"2026-06-03T11:47:35Z","timestamp":1780487255000},"source":"Crossref","is-referenced-by-count":0,"title":["Gastric
