Abstract:
We report a case of a newborn infant who experienced circulatory collapse caused by a calcified lesion occluding the main pulmonary artery (PA). The baby was full-term at birth at a normal birth weight. Cyanosis was noted immediately after birth. Echocardiography revealed a main PA occlusion caused by a calcified lesion. Bradycardia and circulatory failure occurred at postnatal day 4, and an urgent surgical resection was successfully performed. Idiopathic calcification causing both PA obstruction and circulatory collapse is rare. Our report indicates that PA calcification can cause hemodynamic instability requiring early surgical intervention.

Chronic Obstructive Pulmonary Disease
Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...

Chronic Obstructive Pulmonary Disease-III: Symptoms and Complications.
Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.
