Coronavirus disease 2019 (COVID‐19) is a viral disease spread by severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2). Because the recent pandemic has resulted in significant morbidity and mortality, understanding various aspects of this disease has become critical. SARS‐CoV‐2 can affect a variety of organs and systems in the body. The autonomic nervous system plays an important role in regulating body functions, and its dysfunction can cause a great deal of discomfort for patients. In this study, we focused on the effect of COVID‐19 on the autonomic system and syndromes associated with it, such as postural orthostatic syndrome (POTS).

Background: Idiopathic pulmonary artery aneurysm is a rare disorder that has been reported in less than 50 cases. This complication is often asymptomatic, while the first manifestation can be severe hemoptysis or death. Case presentation: A 36-year-old man who presented to our institute with hemoptysis and fever. Dilated pulmonary artery trunk (5.5 cm) and the left pulmonary artery branch (6.90 cm) were discovered during a computed tomography angiogram scan in the patient's chest region. Therefore, the patient was diagnosed with a pulmonary artery aneurysm. According to the results of the tests requested for the patient, the cause of the patient's pulmonary artery aneurysm was not determined. Therefore, an idiopathic pulmonary artery aneurysm was proposed for the patient. Conclusion: Idiopathic pulmonary artery aneurysm poses a double diagnostic and therapeutic problem. The rarity of the disease, the absence of specific clinical signs make diagnosis difficult.

Background Little evidence is available on post-pulmonary embolism impairment (PPEI), a recently defined complication of pulmonary embolism (PE) encompassing dysfunctional clinical and imaging parameters. In the present study, we sought to evaluate its frequency with a focus on the main components. Methods In this prospective registry, we included patients with a confirmed diagnosis of acute PE and focused on those with initial right ventricular (RV) dysfunction. Their baseline, pre-discharge, and 6 month follow-up clinical and imaging characteristics were recorded. The main study outcomes were incomplete RV functional recovery, exercise capacity limitations (based on the 6 minute walk test), and their combination, which defines PPEI, within six months of acute PE. Results Of 170 consecutive patients with a confirmed diagnosis of acute PE, 123 accepted to participate in the follow-up study, of whom 87 had initial RV dysfunction. The 6 month rates of incomplete RV functional recovery, signs of an intermediate-to-high echocardiographic probability of PH, and exercise limitations were observed in 58.6, 32.1, and 45.9%, respectively. A total of 22 (25.2%; 95% CI 15.5-34.4%) patients had PPEI. The RV/LV ratio and the fractional area change on discharge after acute PE were more often impaired among patients with incomplete RV recovery, exercise limitations, and a high probability of PH at 6 months. In contrast, an initial impaired RV diastolic function indices appeared to characterize patients with a limited exercise capacity at 6 months. Discussion PPEI affects one fourth of patients surviving acute PE with half of them presenting with RV dysfunction or exercise limitations.
