    en.wikipedia.org/wiki/Atrioventricular_septal_defect

    When holes form between the chambers, as in AVSD, the pools can mix. Consequently, arterial blood supplies become less oxygenated than normal, causing ischemia and cyanosis in distal tissues. [ 3 ] To compensate, the heart must pump a larger volume of blood to deliver enough oxygen, leading to cardiac enlargement and hypertrophy .

  3. Congenital heart defect - Wikipedia

    en.wikipedia.org/wiki/Congenital_heart_defect

    A congenital heart defect (CHD), also known as a congenital heart anomaly, congenital cardiovascular malformation, and congenital heart disease, is a defect in the structure of the heart or great vessels that is present at birth. [7] A congenital heart defect is classed as a cardiovascular disease. [10]

  4. Acyanotic heart defect - Wikipedia

    en.wikipedia.org/wiki/Acyanotic_heart_defect

    An acyanotic heart defect, is a class of congenital heart defects. In these, blood is shunted (flows) from the left side of the heart to the right side of the heart, most often due to a structural defect (hole) in the interventricular septum. [1] People often retain normal levels of oxyhemoglobin saturation in systemic circulation. [citation ...

    Cardiovascular disease (CVD) is any disease involving the heart or blood vessels. [3] CVDs constitute a class of diseases that includes: coronary artery diseases (e.g. angina, heart attack), heart failure, hypertensive heart disease, rheumatic heart disease, cardiomyopathy, arrhythmia, congenital heart disease, valvular heart disease, carditis, aortic aneurysms, peripheral artery disease ...

    en.wikipedia.org/wiki/Tetralogy_of_Fallot

    Atrioventricular septal defect (AVSD) is an uncommon congenital heart condition characterized by faulty development of the heart's septa and valves. [89] [12] Congestive heart failure is common in infants with the entire version of the condition. [89] [12] Fluid builds up in other parts of the body, particularly the lungs.

  7. Atrial septal defect - Wikipedia

    en.wikipedia.org/wiki/Atrial_septal_defect

    Atrial septal defect (ASD) is a congenital heart defect in which blood flows between the atria (upper chambers) of the heart.Some flow is a normal condition both pre-birth and immediately post-birth via the foramen ovale; however, when this does not naturally close after birth it is referred to as a patent (open) foramen ovale (PFO).

    Heart failure is the result of many diseases affecting the heart, but is most commonly associated with ischemic heart disease, valvular heart disease, or high blood pressure. Less common causes include various cardiomyopathies. Heart failure is frequently associated with weakness of the heart muscle in the ventricles (systolic heart failure ...

  9. Ventricular septal defect - Wikipedia

    en.wikipedia.org/wiki/Ventricular_septal_defect

    Congenital heart disease, particularly VSDs, is the number one cause of death for children with Down syndrome ages birth to two. [7] A VSD can also form a few days after a myocardial infarction [8] (heart attack) due to mechanical tearing of the septal wall, before scar tissue forms, when macrophages start remodeling the dead heart tissue.
