Management of Atrial Fibrillation Suppression in AF-HF Comorbidity Therapy (MASCOT) Trial
2003
Inter- [1,2], intra- [3,4], and atrioventricular [51(AV) dyssynchrony are not new concepts, but only recently have attempts been made to correct these disorders in an effort to treat heart failure (HF). A series of trials [6] has addressed partial or comprehensive cardiac resynchronization in patients with severe HF and evidence of cardiac dyssynchrony. Cardiac resynchronization should improve left ventricular (LV) performance; several trials [7-10] have demonstrated improvement in many hemodynamic parameters (LV and aortic pressure, shortening of mitral diastolic regurgitation, synchronized LV and atrial systole, LV volume, reduced myocardial oxygen consumption) and clinical end-points (qu…
Non-responders to cardiac resynchronization therapy: Insights from multimodality imaging and electrocardiography. A brief review
2016
Background Cardiac resynchronization therapy (CRT) is a successful strategy for heart failure (HF) patients. The pre-requisite for the response is the evidence of electrical dyssynchrony on the surface electrocardiogram usually as left bundle branch block (LBBB). Non-response to CRT is a significant problem in clinical practice. Patient selection, inadequate delivery and sub-optimal left ventricle lead position may be important causes. Objectives In an effort to improve CRT response multimodality imaging (especially echocardiography, computed tomography and cardiac magnetic resonance) could play a decisive role and extensive literature has been published on the matter. However, we are so fa…
Active-fixation coronary sinus pacing lead extraction: A hybrid approach
2012
Cardiac resynchronization therapy (CRT) can be considered as the standard treatment for patients suffering from heart failure (NYHA III–IV), severely reduced left ventricular (LV) function, and wide QRS complexes. Over the past years, the lead systems used to stimulate the left ventricle have evolved technically from epicardial approaches to a transvenous access accompanied by a significant reduction of procedure-related complication rates [1]. However, even today, LV dislodgement rates ranging 5–10% and the instability of thresholds over time remain the greatest challenges with transvenous LV leads in CRT. Therefore, a special LV lead utilizing active fixation (the Attain StarFix® active f…
Jugular pacing lead extraction with laser sheath: a case report.
2010
Over the past 20 years, the number of patients with pacemakers (PM) or implantable cardioverter defibrillators has risen markedly; consequently, an increasing number of lead-removal procedures have become necessary. A 64-year-old woman presenting with an infected device pocket and positive bacterial cultures ( Staphylococcus aureus ) was admitted to our department for lead removal; in 1991, she underwent VVI PM implantation for atrioventricular II degree Mobitz 1 block, and a unipolar lead was introduced via the left jugular vein. The procedure was performed in our Electrophysiology Lab with a cardiac surgeon on standby, using an excimer laser system emitting the energy at the tip of a flex…
Update on Brugada Syndrome 2019
2021
Brugada syndrome (BrS) was first described in 1992 as an aberrant pattern of ST segment elevation in right precordial leads with a high incidence of sudden cardiac death (SCD) in patients with structurally normal heart. It represents 4% ∼ 12% of all SCD and 20% of SCD in patients with structurally normal heart. The extremely wide genetic heterogeneity of BrS and other inherited cardiac disorders makes this new area of genetic arrhytmology a fascinating one. This review shows the state of art in diagnosis, management, and treatment of BrS focusing all the aspects regarding genetics and Preimplant Genetic Diagnosis (PGD) of embryos, overlapping syndromes, risk stratification, familial screeni…
Focus sui non responder alla terapia di resincronizzazione cardiaca: orizzonti e prospettive
2017
Cardiac resynchronization therapy (CRT) has been shown as a successful strategy in the treatment of patients with heart failure and electrical dyssincrony. However, a significant proportion of implanted patients fails to respond sufficiently or in a predictable manner. Consequently, non response to CRT remains a valuable problem in clinical practice. In order to improve CRT response and long-term clinical benefits, the proper evaluation of patient's global frialty, the technology improvement, the multimodality imaging approach and the use of simple and low cost electrographic parameters (to verify effective biventricular capture and QRS narrowing) could play a important role. Therefore, the…
