Il y a 2 jours · 1. Pathophysiology. The pathophysiology of atrial flutter involves the formation of a reentrant circuit, often around the tricuspid valve or along the RA wall. This circuit results in a rapid and regular atrial rhythm. Abnormal intraatrial conduction, slow conduction paths, and areas of low voltage in the atria can contribute to the initiation ...
Il y a 20 heures · Viktoryia Luhakova. L'électroporation cardiaque est une méthode d' ablation cardiaque pour le traitement des arythmies cardiaques chez les patients ne répondant pas aux traitements médicamenteux ou présentant un risque de complications. Son objectif est d'éliminer de petites parties du cœur responsables d'une mauvaise impulsion du muscle.
Il y a 1 jour · Roof-depended atrial flutter was treated with a roof line connecting the PVI circles at the upper part. In cases of typical atrial flutter, ablation of the cavotricuspid isthmus was performed. Intravenous nitrates were administered prior to CTI ablation to avoid the possibility of coronary artery spasms.
Il y a 1 jour · Background Personalized radiofrequency (RF) ablation for paroxysmal atrial fibrillation (PAF), adapting the ablation index (AI) to local left atrial wall thickness (LAWT), proved to be highly efficient maintaining high arrhythmia-free survival rates. However, multicentre data are lacking. This multicentre, prospective, non-randomized study was conducted at 5 tertiary hospitals and sought to ...
Il y a 5 jours · All individuals received pulmonary vein (PV) isolation, and those with atrial flutter underwent selective isthmus ablation. Operators could perform additional ablations as necessary, including posterior wall isolation, roof line creation, targeting non-PV trigger sites, addressing complex fractionated atrial electrograms, or isolating the superior vena cava [ 12 , 13 ].
Il y a 4 jours · To date, radiofrequency (RF) guided high-power-short-duration (HPSD) ablation represents the gold standard besides cryo-ablation for pulmonary vein isolation (PVI). This single-center, retrospective study investigated the efficacy of PFA-PVI versus HPSD-RF PVI in terms of single-procedure arrhythmia-free outcome and safety in a real-world setting.
Il y a 20 heures · Pulmonary vein isolation by transcatheter ablation can restore sinus rhythm. The ganglionated plexi (autonomic ganglia of the heart atrium and ventricles) can also be a source of atrial fibrillation, and is sometimes also ablated for that reason.
