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.
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.
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.
Catheter ablation of most arrhythmias has a high success rate. Success rates for WPW syndrome have been as high as 95% [ 2 ] For Supraventricular tachycardia (SVT), single procedure success is 91% to 96% (95% Confidence Interval) and multiple procedure success is 92% to 97% (95% Confidence Interval).

ACM is a type of heart disease that occurs due to chronic alcohol consumption. The etiology of ACM is multifactorial, with a combination of genetic, environmental, and lifestyle factors playing a role. [2] The direct toxic effects of alcohol on the heart muscle cells (cardiomyocytes) are considered the primary cause of ACM. [2]
Disadvantages include a high rate of complications, such as deep sternal wound infections, in some subgroups of patients—mainly obese and diabetic ones. The left radial artery and left gastroepiploic artery can be also used. Long-term patency is influenced by the type of artery used and intrinsic factors of the cardiac arterial circulation. [41]
Knowledge of the most common and severe complications of a disease, procedure, or treatment allows for prevention and preparation for treatment if they should occur. Complications are not to be confused with sequelae, which are residual effects that occur after the acute (initial, most severe) [1] phase of an illness or injury. Sequelae can ...
Short-term effects of alcohol consumption include intoxication and dehydration. Long-term effects of alcohol include changes in the metabolism of the liver and brain, with increased risk of several types of cancer and alcohol use disorder. [1] Alcohol intoxication affects the brain, causing slurred speech, clumsiness, and delayed reflexes.
