Active clinical trials for "Atrial Flutter"

This study evaluates the impact of educative videos on anxiety for patients entering hospital for cardiology intervention

Decision between rate control and rhythm control can be a challenge in clinical practice. While there is some guiding evidence, we still lack a comprehensive insight into different subgroups of patients that will benefit from a rhythm control treatment. EMPATHY is a prospective clinical study in patients presenting with heart failure and a tachyarrhythmic rhythm disturbance. Biomarkers, routinely obtained results from clinical examinations, and results from endomyocardial biopsies shall be evaluated to identify patients which have better outcome from a rhythm control strategy by ablation therapy or, if contraindicated by pharmacological rhythm control. This study is designed to identifying risk factors and subgroups profiting from rhythm restoration and therefore improve current therapeutic approaches and the rate of recurrence-free survival.

The purpose of this study is to determine, through continuous monitoring with a cardiac monitoring device placed under the skin, the incidence of atrial fibrillation or flutter (AF). The cardiac monitor will be placed in patients without symptoms but at risk for AF. It is hoped that this information may assist health care professionals in treatment decisions related to the early identification of patients at high risk for AF.

The Ablation of the typical atrial flutter can be considered substantially anatomical, the investigators want to test a protocol that foresees the use a lesion index (AI) and that respects the Inter-Lesion Distance (ILD) ≤ 6 mm on the cavo-tricuspid isthmus (CTI) The investigators want to prove how the introduction of a lesion index combined with the continuity of lesion can allow a "first pass block" of the CTI decreasing total Radio-Frequency (RF) times

The purpose of this study is to perform ultra-high density mapping of the left atrium (a chamber of the heart) using the the Rhythmia Mapping System and to determine whether additional ablation in areas of wavefront discontinuities identified by the map will reduce the likelihood of both atrial fibrillation and atrial flutter.

The aim of the study is to assess the prevalence of left atrial thrombus in patients with atrial fibrillation (AF) or atrial flutter (AFI), in whom transesophageal echocardiography is performed before AF/AFl cardioversion or ablation.

The investigators propose a third hypothesis based on the anatomic observations made in pathological studies. The investigators hypothesize that the anatomic architecture determines the functional properties of the TV-IVC isthmus. As a result, • Muscular bundles are preferential routes of conduction through the TV-IVC isthmus. The isthmus acts like a series of discreet conduction routes rather than as a sheet of tissue. The muscular bundles form selective targets for ablation and therefore the entire anatomic line need not be ablated. This has direct implications for ablation of the isthmus.
