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.
In a select population with symptoms secondary to a high outflow tract gradient, alcohol septal ablation can reduce the symptoms of HCM. In addition, older individuals and those with other medical problems, for whom surgical myectomy would pose an increased procedural risk, would likely benefit from the less-invasive septal ablation procedure.
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.
According to a recent study, baby teeth contain an abundance of stem cells, a very special type of cell that can potentially grow replacement tissue in the body and cure a number of diseases.
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.
A crown may be needed when a large dental cavity threatens the health of a tooth. Some dentists will also finish root canal treatment by covering the exposed tooth with a crown. [1] A crown is typically bonded to the tooth by dental cement. They can be made from various materials, which are usually fabricated using indirect methods. Crowns are ...
At a median follow up of 18 months, patients undergoing the hybrid procedure also had a significantly higher freedom from major adverse cardiac or cerebrovascular events (99% vs. 90.4%; p = 0.03). [ citation needed ] HCR is also associated with a significant decrease in the need for blood transfusion and a significant reduction in the duration ...
The procedure was developed to treat transposition of the great vessels, eponymously known as blue baby syndrome. This is a condition in which the aorta and pulmonary artery are attached to the heart in an opposite order from what is usually present at birth, resulting in the aorta being the outflow tract for the right ventricle and the ...
