Patent foramen ovale (PFO) is a common congenital atrial septal defect with an incidence of 15%–35% in the adult population. The development of the interatrial septum is a process that begins in the fourth gestational week and is completed only after birth. During intrauterine life, the foramen ovale allows the passage of highly oxygenated blood from the right to the left atrium and into the systemic arteries, thus bypassing the pulmonary circulation. In 75% of the general population, the foramen ovale closes after birth, and only an oval depression, called fossa ovalis, remains on the right side of the interatrial septum. Patent foramen ovale can be associated with various clinically important conditions, including migraine and stroke, or decompression illness in divers. The aim of this review is to summarize the PFO developmental and anatomical features and to discuss the clinical risks associated with this atrial septal defect in adults.

Aim: Forward head posture (FHP) is a very common pathological neck posture among people who frequently use multimedia devices, and it could be related to some musculoskeletal disorders. However, its role in influencing lung function and its relationship with neck disability are still debated in the literature. Therefore, the aim of the present study was to investigate the influence of FHP on respiratory function, and to explore a possible relationship between FHP and neck discomfort. Methods: A cross-sectional study was conducted on a sample of 83 subjects (35.7 ± 8.4 years aged), enrolled at the Ferrari corporate wellness program “Formula Benessere”. Craniovertebral angle (CVA) was measured with a digital goniometer to assess head posture: FHP was defined with a CVA < 50° in an upright position. Spirometry was conducted according to European Respiratory Society/American Thoracic Society (ERS/ATS) criteria. Finally, subjects enrolled were evaluated through a self-administered neck disability index (NDI) questionnaire. Results: Among the 60 participants with agreement about the CVA measurements, 45 had FHP (11 females and 34 males) with lower CVA values. No significant differences were found in spirometric parameters between subjects with FHP (n = 45) and subjects without FHP (n = 15). Furthermore, the two groups did not differ either in NDI scores (P = 0.148). Conclusions: There is no clear relationship between FHP and respiratory function indices. Moreover, no differences have been found in NDI values between subjects with FHP and subjects without FHP. Respiratory rehabilitation strategies should be focused on other parameters than FHP itself.
