Pulmonary embolism (PE) is a blockage of blood flow in the pulmonary artery bed that can result in a life-threatening and potentially reversible right ventricular failure [1]. PE remains one of the leading causes of poor prognosis and death, particularly when a shock or right ventricular failure occurs [2]. According to studies, PE is generally manifested in a nonspecific manner

Pulmonary Arterial Hypertension (PAH) represents a rare but devastating disease due to small pulmonary arterial vessels remodelling and increased pulmonary vascular resistance leading to right ventricular dysfunction, right heart failure and death.

A 69-year-old woman with hypertension, hyperlipidemia, sleep apnea, gastroesophageal reflux disease, and recent knee replacement was brought to the emergency room (ER) for syncope. She had her physiotherapy session earlier in the day and became symptomatic with dizziness, shortness of breath and had loss of consciousness.

Acute pulmonary embolism (PE) is when one or more thrombus travel to the lungs and obstruct the pulmonary artery or one of the branches of the pulmonary tree, producing signs and symptoms immediately after the obstruction. Saddle pulmonary embolism (SPE) is a rare type of acute PE that can lead to hemodynamic instability and death. The incidence of pulmonary embolism increases with age. In women, the risk of PE increases with pregnancy, hormonal contraceptives, and hormone replacement therapy.
