Balloon septostomy is the widening of a foramen ovale, patent foramen ovale (PFO), or atrial septal defect (ASD) via cardiac catheterization (heart cath) using a balloon catheter. This procedure allows a greater amount of oxygenated blood to enter the systemic circulation in some cases of cyanotic congenital heart defect (CHD). Two structures in the human body are called foramen ovale, meaning circular hole. ... An atrial septal defect (ASD) is a group of congenital heart diseases that involve the inter-atrial septum of the heart. ... Atrial septal defects (ASD) are a group of congenital heart diseases that involve the interatrial septum of the heart. ... Cardiac catheterization (heart cath) is the insertion of a catheter into a chamber or vessel of the heart. ...

Red blood cells (erythrocytes) are present in the blood and help carry oxygen to the rest of the cells in the body Blood is a circulating tissue composed of fluid plasma and cells (red blood cells, white blood cells, platelets). ... Systemic circulation is a circuit of circulation in the cardiovascular system. ... A cyanotic heart defect is a congenital heart defect. ... A congenital disorder is a medical condition or defect that is present at or before birth (for example, congenital heart disease). ... A congenital heart defect is a defect in the structure of the heart and great blood vessels of the newborn. ...

After the initial catheterization (see cardiac catheterization), the deflated balloon catheter is passed from the right atrium through the foramen ovale, PFO or ASD into the left atrium, it is then inflated and pulled back through to the right atrium, thereby enlarging the opening and allowing greater amounts of blood to pass through it. The resulting man-made opening, or passage, is one of many forms of shunting, and is often referred to as an ASD. Cardiac catheterization (heart cath) is the insertion of a catheter into a chamber or vessel of the heart. ... DEFLATE is a lossless data compression algorithm that uses a combination of the LZ77 algorithm and Huffman coding. ... This page is about the muscular organ, the Heart. ... An inflatable is an object that can be inflated, usually with air, but hydrogen, helium and nitrogen are also used. ... In medicine, a shunt is a device designed to drain excess cerebrospinal fluid from the brain and carry it to other parts of the body. ...

This is normally a palliative procedure used to prepare a patient for, or sustain them until, a corrective surgery can be performed. It is at this time that the ASD is closed using either sutures or a cardiac patch, depending on the size and/or nature of the opening. Palliative care is any form of medical care or treatment that concentrates on reducing the severity of the symptoms of a disease or slows its progress rather than providing a cure. ...
