Pulsed field ablation (PFA) is a non-thermal (not using extreme heat or cold) method of biological ablation (removal of structure or functionality) utilizing high-amplitude pulsed (microsecond duration) electric fields to create irreversible electroporation in tissues. [1] [2] It is used most widely to treat tumors or cardiac arrhythmias. [3]
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]
Mitral valve replacement is a procedure whereby the diseased mitral valve of a patient's heart is replaced by either a mechanical or tissue (bioprosthetic) valve. The mitral valve may need to be replaced because: [1] The valve is leaky (mitral valve regurgitation) The valve is narrowed and doesn't open properly (mitral valve stenosis)
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]
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.
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.
Surgical ablation of atrial fibrillation with off-pump, epicardial, high-intensity focused ultrasound: Although the HIFU minimaze is performed epicardially, on the normally beating heart, it is also usually performed in conjunction with other cardiac surgery, and so would not be minimally invasive in those cases.
A valvulotomy, valvotomy, [1] valvuloplasty, or valvoplasty is a procedure used in heart valve surgery that consists of making one or more incisions at the edges of the commissure formed between the two (mitral valve), or three tricuspid valve leaflets. This relieves the constriction of valvular stenosis (especially mitral valve stenosis ...
