Heart septal defect refers to a congenital heart defect [1] of one of the septa of the heart. Atrial septal defect; Atrioventricular septal defect; Ventricular septal defect; Although aortopulmonary septal defects are defects of the aorticopulmonary septum, which is not technically part of the heart, they are sometimes grouped with the heart ...
Ventricular septal defect is usually symptomless at birth. It usually manifests a few weeks after birth. [citation needed] VSD is an acyanotic congenital heart defect, aka a left-to-right shunt, so there are no signs of cyanosis in the early stage. However, an uncorrected VSD can increase pulmonary resistance leading to the reversal of the ...
A VSD can cause a left-to-right shunt of blood flow in the heart and is one of the most common of the congenital heart defects. This type of shunt is an acyanotic disorder that can result in ventricular hypertrophy. [4] The alignment of interventricular septum and interatrial septum is disturbed in various congenital heart diseases. [5]
Cardiomyopathy refers to a diseased heart muscle. The disease makes it difficult for the heart to pump blood throughout the body. ... An atrial septal defect is a hole between the two upper ...
In many cases, TGV is accompanied by other heart defects, the most common type being intracardiac shunts such as atrial septal defect including patent foramen ovale, ventricular septal defect, and patent ductus arteriosus. Stenosis, or other defects, of valves and/or vessels may also be present. [citation needed]
Pulmonary valve defects resulting in tricuspid regurgitation, a common effect of pulmonary stenosis, can cause this increase in muscle mass. [5] Atrial septal defect An atrial septal defect is a hole in the septum that divides the right and left atria (the upper two chambers) of the heart. In the heart of a developing fetus, there are several ...
Mutations of a heart muscle protein, α-myosin heavy chain are associated with atrial septal defects. [25] Several proteins that interact with MYH6 are also associated with cardiac defects. The transcription factor GATA4 forms a complex with the TBX5 which interacts with MYH6.
Noncompaction cardiomyopathy (NCC) is a rare congenital disease of heart muscle that affects both children and adults. [1] It results from abnormal prenatal development of heart muscle. [2] [3] During development, the majority of the heart muscle is a sponge-like meshwork of interwoven myocardial fibers.
