Abstract

In December 2019, a serious number of patients with pneumonia was first announced in Wuhan and, since March 11, 2020, the World
Health Organization (WHO) has declared coronavirus disease 2019 (COVID-2019) caused by SARS-CoV-2 to be a pandemic and a very
severe global health problem. Severity about this disease is associated with an increasing age and comorbidities such as chronic heart and lung
disease. Chronic thromboembolic pulmonary hypertension (CTEPH), another important and fatal disease, is a specific type of pulmonary
hypertension characterized by obstruction or occlusion of subsegmental, segmental, or larger pulmonary arteries by the post-embolic fibrotic
material which has a definitive cure by pulmonary endarterectomy performed under cardiopulmonary bypass and total circulatory arrest. In
this article, we examined thoroughly and enlightened some of the gray zones in CTEPH patients for healthcare providers with the aim of
providing a reasonable algorithm in the era of COVID-19 pandemic.

Key words: COVID-19, pandemic, pulmonary heart disease
