A patient affected by COVID-19 pneumonia may develop pulmonary hypertension (PH) and secondary right ventricular (RV) involvement, due to lung parenchymal and interstitial damage and altered pulmonary haemodynamics, even in non-advanced phases of the disease. This is a consequence of hypoxic vasoconstriction of the pulmonary circulation, the use of positive end-expiratory pressure (PEEP) in mechanical ventilation, pulmonary endothelial injury, and local inflammatory thrombotic and/or thromboembolic processes. We report the case of a young man admitted with a diagnosis of COVID-19 pneumoniae with PH unrelated to viral infection and in whom partial anomalous pulmonary venous drainage (PAPVD) was eventually diagnosed.
Learning points: COVID-19 patients, even if previously well, can have pulmonary hypertension due to other causes.The cause of pulmonary hypertension should always be sought and not assumed, even in COVID-19 patients.
Keywords: COVID-19; partial anomalous pulmonary venous drainage; pulmonary hypertension; right ventricular involvement.
