Symptoms include: Bluish skin (cyanosis) Delayed growth or growth failure Fatigue Lethargy Poor feeding Rapid breathing (tachypnea) Shortness of breath (dyspnea) Widening of the finger tips (clubbing) Surgery is needed to treat this condition. [medlineplus.gov]

Progressive pulmonary hypertension Leaky heart valves (regurgitation) Heart rhythm disturbances (arrhythmias) Problems related to prior operation Common signs and symptoms of these complications include shortness of breath when exercising, dizziness, fatigue [mayoclinic.org]

The unoperated natural history of TA patients is extremely poor, with death in infancy or early childhood due to severe heart failure, subsequent pulmonary vascular occlusive disease, endocarditis and cerebral abscess. [jcmr-online.biomedcentral.com]

Without surgical intervention, death in infancy is the rule. [ncbi.nlm.nih.gov]

Rare forms that do not fall into these classifications may occur. Although several cases of diagnosis in foetus 4,5 life have been described, the diagnosis is made in the neonatal period or in childhood. [scielo.br]

Knowing that it is a rare association of truncus with systemic-pulmonary collateral arteries, the most likely hypothesis to justify such an occurrence is that they have been acquired over the patient's life, 28 years old and not operated. [scielo.br]

[…] the large and small circulatory system is possible. 5.2 Disturbances during the formation and separation of the atria If the opening of the foramen ovale take place postnatally, this can cause small clots ( thrombi ) from the body's periphery to form over [flexikon.doccheck.com]

The aortic valve is actually the large truncal valve from the single vessel, which arose over the ventricular septal defect before surgical repair. This valve sometimes becomes leaky over time and may need to be replaced. [heart.org]

Over time, it becomes very hard for the heart to force blood to them. This is called pulmonary hypertension, which can be life threatening. [medlineplus.gov]

Avoid the use of supplemental oxygen as this may worsen pulmonary over-circulation. [ncbi.nlm.nih.gov]

On this occasion, the patient was in good general condition, acyanotic, cardiac auscultation with a continuous murmur /4 throughout the precordium accompanied by fremitus. [scielo.br]

hypertrophy Cardiomegaly Increased pulmonary vascularity Hypocalcemia (if associated with DiGeorge syndrome) Classification[edit] A well-known classification is the fourfold system developed by Collett and Edwards in 1949.[9] Collett/Edwards Types I, [en.wikipedia.org]
