With the appearance of the new SARS-COV2 virus, additional challenges are being imposed on the medical community after the resolution of acute COVID-19 illness, resulting in specific pathophysiologic mechanisms that while acutely damage the lung parenchyma might chronically impact the cardiopulmonary system.
