Long-standing persistent atrial fibrillation : what can we achieve with ablation?
Nunes-Ferreira, Afonso; Cortez-Dias, Nuno; Silverio Antonio, P.; Silva, Gustavo Lima da; Gonçalves, Inês; Aguiar-Ricardo, Inês; Rigueira, JoanaIntroduction: Atrial fibrillation (AF) ablation presents suboptimal results in patients (pts) with persistent long-lasting forms (LSPAF, AF ≥12 months). Recently, the STAR AF-II trial has shown that in these pts complex additional strategies do not improve success compared to only performing pulmonary vein isolation (PVI). Objectives: To evaluate the success of AF ablation, particularly in long-standing persist...
First intention epicardial VT ablation : what are the results?
Rodrigues, T. E. Graça; Cortez-Dias, Nuno; Silva, Gustavo Lima da; Agostinho, João R.; Aguiar-Ricardo, Inês; Rigueira, Joana; Nunes-Ferreira, AfonsoIntroduction: Ventricular tachycardia (VT) endocardial mapping and ablation may not be sufficient in several arrhythmogenic contexts, because ventricular myocardium may comprise intricate endocardial, intramural and epicardial substract. Thus, epicardial ablation has lately become a complementary and necessary tool to approach some VTs in different types of cardiomyopathies.
Atrial fibrillation ablation : the added value of adenosine test in confirming ...
Nunes-Ferreira, Afonso; R. Agostinho, João; Cortez-Dias, Nuno; Silva, G. Lima da; Francisco, Ana Rita; Guimarães, T.; Gonçalves, I. SantosIntroduction: Adenosine test has been increasingly used to confirm pulmonary vein isolation (PVI) in patients undergoing ablation of atrial fibrillation (AF). However, its impact on the success of ablation remains unknown. Purposes: To evaluate the results of the adenosine triphosphate (ATP) test in patients undergoing PVI and assess the success of ablation related to the use of this test (adenosine-guided PVI ...
Implantation of ICD and CRT-D in the elderly population : will it be a limiting...
Ricardo, I. Aguiar; Dias, Nuno Cortez; Marques, P.; Magalhães, A.; Gonçalves, I.; Agostinho, J.; Silva, G. Lima da; Guimarães, T.; Santos, I.Introduction: Implantable cardioverter defibrillator (ICD) and cardiac resynchronization (CRT-D) implantation in elderly patients is effective in preventing sudden death, although limited by the natural shorter life expectancy. The different device brands present very variable survival estimates and it has been discussed the availability of less expensive, less longevity generators for the elderly population. P...
Utility of pace-matching mapping in the ablation of idiopathic ventricular tach...
Gonçalves, I. S. S.; Silva, G. L.; Agostinho, J. R.; Guimarães, T.; Francisco, A. R.; Ricardo, I. A.; Rigueira, J.; Quaresma, J.; Barreiros, C.Introduction: The electroanatomical mapping of idiopathic ventricular tachyarrhythmias (iVT) - premature ventricular contractions (PVC) and idiopathic ventricular tachycardia (VT) - is dependent on the recording of spontaneous PVC or induction of the clinical VT during the procedure to obtain the iVT activation map. The presence of infrequent and non-inducible iVT may preclude ablation. Pace-matching (PM) mappi...
