Pulmonary Artery Intimal Sarcoma Diagnosed Preoperatively by Endovascular Biopsy and Treated via Right Pneumonectomy and Pulmonary Arterioplasty

Case Reports in Pulmonology, 2021
Introduction. Intimal sarcoma is a very rare tumor arising within the intima of the pulmonary artery. Preoperative diagnosis of pulmonary artery sarcoma is difficult, and the tumor is sometimes misdiagnosed as pulmonary thromboembolism.

Pulmonary artery blood flow dynamics in chronic thromboembolic pulmonary hypertension

Scientific Reports, 2023
Chronic thromboembolic pulmonary hypertension is caused by incomplete resolution and organization of thrombi. Blood flow dynamics are involved in thrombus formation; however, only a few studies have reported on pulmonary artery blood flow dynamics in ...

Frequency of various cardiac complications in children with repaired tetralogy of Fallot identified by computer tomography [PDF]

Digital Diagnostics, 2023
BACKGROUND: Tetralogy of Fallot represents 7–10% of all cases of congenital heart disease, as it occurs in approximately 0.5 per 1,000 live births and is the second most common form of complex congenital heart disease.

Pulmonary arterial hypertension [PDF]

Breathe, 2005
Key pointsPAH is defined by RHC showing a pre-capillary PH.Clinical suspicion of PH should arise in the case of symptoms such as dyspnoea without overt signs of specific heart or lung disease.RHC is required to confirm the diagnosis of PAH, to assess the severity of the haemodynamic impairment and to test the vasoreactivity of the pulmonary circulation.

Pulmonary artery filling defects - Not all are pulmonary emboli

Sri Lanka Journal of Medicine, 2023
Differentiating pulmonary artery sarcoma from pulmonary artery emboli is challenging since the clinical presentation and imaging features of both conditions are often similar. Timely differentiation of the two conditions is important as delayed diagnosis
