Alcohol septal ablation (ASA) is a minimally invasive heart procedure to treat hypertrophic cardiomyopathy (HCM). [1]It is a percutaneous, minimally invasive procedure performed by an interventional cardiologist to relieve symptoms and improve functional status in eligible patients with severely symptomatic HCM who meet strict clinical, anatomic and physiologic selection criteria.
Septal myectomy is associated with a low perioperative mortality and a high late survival rate. A study at the Mayo Clinic found surgical myectomy performed to relieve outflow obstruction and severe symptoms in HCM was associated with long-term survival equivalent to that of the general population, and superior to obstructive HCM without operation.
The Amplatzer device from St. Jude Medical, used to close atrial septal defects, has also been used to occlude the left atrial appendage. [21] [22] This can be performed without general anaesthesia and without echocardiographic guidance. Transcatheter patch obliteration of the LAA has also been reported. [15]
The Mustard procedure was developed in 1963 by Dr. William Mustard at the Hospital for Sick Children.It is similar to the previous atrial baffle used with a Senning procedure, the primary difference being that the Mustard uses a graft made of Dacron or pericardium, while the Senning uses native heart tissue.
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.
Snares and tapes are used to facilitate exposure. The aim is to avoid distal ischemia caused by blockage of the vessel supplying distal portions of the left ventricle, so usually LITA to LAD is the first to be anastomosed and others follow. For the anastomosis, a fine tube blowing humidified CO 2 keeps the surgical field clean of blood. Also, a ...
Catheter ablation is a procedure that uses radio-frequency energy or other sources to terminate or modify a faulty electrical pathway from sections of the heart of those who are prone to developing cardiac arrhythmias such as atrial fibrillation, atrial flutter and Wolff-Parkinson-White syndrome.
Alfred Blalock was an American surgeon most known for his work on the Blue Baby syndrome. [2] C. Rollins Hanlon was also an American surgeon but was best known for his work in cardiology. [3] The procedure that these two men created, known as the Blalock–Hanlon procedure, was a new concept termed atrial septectomy.
