ABSTRACT
INTRODUCTION: Dextrocardia is characterized by the positioning of the heart to the right of the thoracic cavity, usually with the apex oriented to the right and its inverse anatomy 1,2. It is a rare congenital pathology that can be associated with other congenital cardiac anomalies, as well as a change in position of all thoracoabdominal structures 1-4. Its diagnosis in adult life is usually incidental. We present the clinical case of a 64-year-old man with an electrocardiogram that showed deviation of the QRS complex axis to the extreme right and a physical examination compatible with dextrocardia, which was later confirmed with images. OBJECTIVES: To review the medical literature related to the diagnosis of dextrocardia through the presentation of a clinical case. METHODS: The clinical data of the case were collected by means of anamnesis, physical examination and specialized exams of the patient, as well as his clinical file. The literary review was made using the MEDLINE® search engine for scientific journals. RESULTS: Dextrocardia affects less than 1% of the general population according to the studies reviewed. Its importance lies in the association with other congenital pathologies such as cardiac and extracardiac structural malformations, which increases morbidity and mortality in this group of patients. It is imperative, when suspected, complete the study with images that allow confirming or ruling out other structural anomalies.

Objetivos: describir la frecuencia de estenosis arterial (cubital y radial) en pa-cientes con esclerosis sistémica (ES); analizar la relación entre estenosis macro-vascular y úlceras digitales. Método: se incluyeron 57 pacientes con ES, según la clasificación del Colegio Americano de Reumatología de 1980 y 21 pacientes sin ES. Se realizó ecografía doppler arterial de miembros superiores. Resultados: la estenosis en al menos una arteria cubital se objetivó en 31% de pacientes con ES (18/57) (p=0.003). Se objetivó estenosis radial en 9 de 57 pacientes con ES (15%) y en uno de los 21 controles (p=0.19). En el modelo multivariado, los predicto-res de úlceras digitales fueron inicio de Raynaud antes de los 40 años (OR 5.3 IC95% 1.54-18.22, p=0.008) y patrón tardío en la capilaroscopia (OR 4.4 IC95% 1.29-15.63, p=0.018). Conclusiones: un tercio de los pacientes ES presentó este-nosis cubital. El compromiso de los grandes vasos no se asoció a úlceras digitales.
Objectives: to describe the frequency of ulnar and radial stenosis in SSc patients. Analyze the correlation between arterial stenosis and digital ulcers. Methods: we included 57 SSc consecutive patients who fulfilled ACR 1980 classification criteria, and 21 healthy controls. An arterial ecodoppler was performed to all participants. Results: the presence of stenosis in at least one ulnar artery was observed in 18 of 57 patients with SSc (31%) and in none of the 21 controls (p=0.003). Stenosis was present in at least one radial artery in 9 of 57 SSc patients (15%) (p=0.19). In multivariate model, the best predictors of digital ulcers were age at onset of Ray-naud phenomenon before 40 years (OR 5.3 95%CI 1.54-18.22, p=0.008) and late SD pattern (OR 4.4 95%CI 1.29-15.63, p=0.018). Conclusion: in the present series, ulnar stenosis was observed frequently in SSc patients. Stenosis of large vessels was not associated with digital ulcers.
