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.
Ordinarily, septal myectomies are performed only after attempts at treatment with medication fail. The choice between septal myectomy and alcohol ablation is a complex medical decision. [citation needed] Septal myectomy was established by Andrew G. Morrow in the 1960s. [3]
When performed properly, an alcohol septal ablation induces a controlled heart attack, in which the portion of the interventricular septum that involves the left ventricular outflow tract is infarcted and will contract into a scar. There is debate over which people are best served by surgical myectomy, alcohol septal ablation, or medical therapy.
A heart attack requires immediate treatment to improve blood flow to your heart, relieve your symptoms, and prevent another heart attack. Some treatment options include: Some treatment options ...
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.
For selected patients, a trial of oral disopyramide is a reasonable approach before proceeding to invasive septal reduction. Patients who respond to disopyramide are continued on the drug. Those who continue to have disabling symptoms or who experience side effects are promptly referred for septal reduction.
A conduit can be used to graft one or more native arteries. In the latter case, an end-to-side anastomosis is performed. In the former, using a sequential anastomosis, a graft can then deliver blood to two or more native vessels of the heart. [21] Also, the proximal part of a conduit can be anastomosed to the side of another conduit.
Since then, the Cox-Maze IV procedure is the gold standard surgical treatment for AF with conversion to normal sinus rhythm and freedom from AF at 1 year postoperatively of 93%, [4] [5] but the results are institution dependent. [6]
