Abstract:
There is often a two-year delay in the diagnosis of Pulmonary Hypertension (PH) because the initial symptoms (dyspnoea and fatigue) are frequently attributed to other comorbidities. In addition, it is diagnosed by an invasive technique: right heart catheterization (RHC), responsible for the appearance of adverse events such as arrhythmias, hypotension and pneumothorax, among others. Non-invasive tests are playing an important role in early detection. A tomographic marker, the egg and banana sign (EBS) was recently introduced, which could contribute to the diagnosis.
Objectives: To determine if EBS is a sensitive and specific diagnostic marker for PH. To re-evaluate the correlation between the principal diameter of the pulmonary artery (PA) and the pulmonary artery-ascending aorta ratio (PA-Ao ratio) both individually and in combination with EBS.
A total of 42 patients were evaluated who, between 2017 and 2021, underwent RHC and CT that included the aortic arch. Two blind observers determined whether EBS was present or absent on CT scans. Qualitative data were described using absolute and relative frequencies, ROC curves. The Chi Square test was performed for the association between variables. P <0.05 was considered statistically significant. The work was approved by the Departamento de Investigación y Docencia del Hospital Italiano de Córdoba.
Of the total number of patients, 19 had PH and 23 were control subjects. 75% of the patients in whom EBS was observed had PH with an average mPAP of 39 mmHg (Sensitivity: 62%; Specificity: 88.24%; P: 0.036). Regarding the PA, EBS was observed in patients with a diameter greater than 32 mm, with an average of 40mm. (Sensitivity: 75%; Specificity: 82%; p = 0.0001). Of the patients with PH, 74% had a PA-Ao ratio greater than 1 (p: 0.0034).
Conclusion: in our population EBS presented a high specificity for mPAP from 39 mmHg. In association with the diameter of the PA, the classic marker, both its sensitivity and specificity were high.

Resumen: A menudo se produce un retraso de dos años en el diagnóstico de Hipertensión Pulmonar (HP) porque los síntomas iniciales (disnea y fatiga) se atribuyen con frecuencia a otras comorbilidades. Además, se diagnostica mediante una técnica invasiva: el cateterismo cardiaco derecho (CCD), responsable de la aparición de eventos adversos como arritmias, hipotensión y neumotórax, entre otros. Las pruebas no invasivas están desempeñando un papel más importante en la detección precoz. Se introdujo recientemente un marcador tomográfico, el signo de huevo y la banana (SHB), que podría contribuir en el diagnóstico. Objetivos: Determinar si el SHB es un marcador diagnóstico sensible y específico para la HP. Reevaluar la correlación entre el diámetro principal de arteria pulmonar (AP) y la relación de arteria pulmonar-aorta ascendente (relación AP-Ao) tanto individualmente como en combinación con el SHB. Se evaluó un total de 42 pacientes que, entre 2017 a 2021, se realizaron CCD y se sometieron a TC que incluyeran el arco aórtico. Dos observadores ciegos determinaron si el SHB estaba presente o ausente en las TC. Los datos cualitativos se describieron utilizando frecuencias absolutas y relativas, se realizaron curvas ROC, y para la asociación entre las variables se realizó test de Chi2. P <0,05 se consideró significativo. El trabajo fue aprobado por el Departamento de Investigación y Docencia del Hospital Italiano de Córdoba. Del total de pacientes, 19 tenían HP y 23 representaron los sujetos control. El 75% de los pacientes en los que se observó el SHB presentaba HP con una PAPm promedio de 39 mmHg (Sensibilidad: 62%; Especificidad: 88,24%; p: 0,036). Con respecto a la AP, se observó el SHB en pacientes con un diámetro mayor a 32mm, con un promedio de 40mm. (Sensibilidad: 75%; Especificidad: 82%; p= 0,0001). De los pacientes con HP el 74% tenían una relación AP-Ao mayor a 1 (p: 0,0034). En conclusión, en nuestra población, el SHB presentó una alta especificidad para una PAPm a partir de 39 mmHg. En asociación con el diámetro de la AP, el marcador clásico, tanto su sensibilidad como la especificidad fueron elevadas. . Universidad Nacional Córdoba. Facultad de Ciencias Médicas.
