Atrial septostomy is a surgical procedure in which a small hole is created between the upper two chambers of the heart, the atria.This procedure is primarily used to palliate dextro-Transposition of the great arteries or d-TGA (often imprecisely called transposition of the great arteries), a life-threatening cyanotic congenital heart defect seen in infants.
St Jude Medical's Portico Transcatheter aortic valve received European CE mark approval in December 2013. The valve is repositionable before release to ensure accurate placement helping to improve patient outcomes. [12] Edwards' Sapien aortic valve is made from bovine pericardial tissue and is implanted via a catheter-based delivery system. It ...
On April 18, 2019, Edwards completed the acquisition of CAS Medical Systems of Branford, Connecticut for ~$100 million. [14] Edwards SAPIEN 3 and SAPIEN 3 Ultra Transcatheter Heart Valve systems were FDA-approved for the treatment of patients at low risk for death or major complications associated with open-heart surgery on August 16, 2019.

A pulmonary homograft (a pulmonary valve taken from a cadaver) is then used to replace the patient's own pulmonary valve. This procedure was first performed in 1967 and is used primarily in children, as it allows the patient's own pulmonary valve (now in the aortic position) to grow with the child. [17] Tissue valves can last 10–20 years. [18]
Transcatheter pulmonary valve replacement (TPVR), also known as percutaneous pulmonary valve implantation (PPVI), is the replacement of the pulmonary valve via catheterization through a vein. It is a significantly less invasive procedure in comparison to open heart surgery and is commonly used to treat conditions such as pulmonary atresia. [2] [3]

The Starr-Edwards valve was first implanted in a human on August 25, 1960, and was discontinued by Edwards Lifesciences in 2007. [13] Caged ball valves are strongly associated with blood clot formation, so people who have one required a high degree of anticoagulation, usually with a target INR of 3.0–4.5. [14]
