Scimitar syndrome, or congenital pulmonary venolobar syndrome, is a rare congenital heart defect characterized by anomalous venous return from the right lung (to the systemic venous drainage, rather than directly to the left atrium). [1] This anomalous pulmonary venous return can be either partial (PAPVR) or total (TAPVR).

A right-sided aortic arch does not cause symptoms on itself, and the overwhelming majority of people with the right-sided arch have no other symptoms. However, when it is accompanied by other vascular abnormalities, it may form a vascular ring , causing symptoms due to compression of the trachea and/or esophagus .
If an anomaly is detected during a routine ultrasound, a fetal echocardiogram is performed to determine whether a fetus has the condition. [8] Otherwise, it is often unnoticed unless an extenuating circumstance warrants further examination of the heart, usually much later in life.
The severity of symptoms, and thus the likelihood of diagnosis, varies significantly depending on the amount of blood flow through the anomalous connections. In less severe cases, with smaller amounts of blood flow, diagnosis may be delayed until adulthood, when it can be confused with other causes of pulmonary hypertension. [ 5 ]
Pulmonary artery stenosis (PAS) is a narrowing of the pulmonary artery.The pulmonary artery is a blood vessel moving blood from the right side of the heart to the lungs. . This narrowing can be due to many causes, including infection during pregnancy, a congenital heart defect, a problem with blood clotting in childhood or early adulthood, or a genetic ch
[4] Adolescent males with the condition have shown to presents with symptoms such as spontaneous lower extremity DVT, leg swelling, leg pain, varices in the lower extremities, hepatic thrombosis and hematochezia. [4] [5] Chylothorax has been observed rarely as a symptom of congenital stenosis of the superior vena cava in infant patients.
Pulmonary capillary hemangiomatosis (PCH) is a disease affecting the blood vessels of the lungs, where abnormal capillary proliferation and venous fibrous intimal thickening result in progressive increase in vascular resistance. [1]
