n.
1. Surgical excision or amputation of a body part or tissue.
2. The erosive processes by which a glacier is reduced.
3. Aerospace

b. The reduction or removal of heat-protective surface material by aerodynamic friction, as from a heat shield.

[Late Latin ablātiō, ablātiōn-, from Latin ablātus, past participle of auferre, to carry away : ab-, away; see ab-1 + lātus, carried; see telə- in Indo-European roots.]

ab·la·tion

(ă-blā′shən)
1. The wearing away or destruction of the outer or forward surface of an object, such as a meteorite or a spacecraft, as it moves very rapidly through the atmosphere. The friction of the air striking the object heats and often melts or burns its outer layers.
2. The process by which snow and ice are removed from a glacier or other mass of ice. Ablation typically occurs through melting, sublimation, or wind erosion.

For asymptomatic patients in whom electrophysiology testing identifies high-risk properties, catheter ablation is recommended; catheter ablation should also be considered for patients with asymptomatic pre-excitation and a low-risk accessory pathway at invasive or noninvasive risk stratification and for patients with asymptomatic pre-excitation and left ventricular dysfunction due to electrical dyssynchrony.
Razminia developed a "fluoroless catheter ablation" procedure to treat cardiac arrhythmia, or irregular heart beat.
The results from a 10-year randomized trial known as the CABANA trial (Catheter Ablation versus Antiarrhythmic Drug trial for Atrial Fibrillation) have recently been released.
In an exclusive report, Transparency Market Research has compiled a range of sections analyzing the expansion of the global EP Catheter Ablation Market for the assessment period, 2017-2026.

SAN FRANCISCO -- Catheter ablation of atrial fibrillation (AFib) in the roughly one-third of patients with heart failure (HF) enrolled in the CABANA multicenter, randomized trial produced striking, statistically significant improvements both in the study's primary, combined endpoint and in all-cause mortality in intention-to-treat analyses.

Objectives: To review 10 years of clinical practice of cardiac electrophysiology study and radiofrequency catheter ablation in the treatment of supraventricular tachycardia.
A trial of patients with symptomatic atrial fibrillation (Afib) has shed new light on the benefits of catheter ablation. Ablation is generally reserved for patients on anti-arrhythmia medications who continue to experience Afib.
The success of catheter ablation for typical AFl is very high.
Today, more patients with Afib gain relief through catheter ablation, an interventional procedure that can maintain the heart's normal sinus rhythm.
