Feasibility and performance of catheter ablation with zero-fluoroscopy approach for regular supraventricular tachycardia in patients with structural and/or congenital heart disease.

Aleksandra Morka, Janusz Śledź, Karol Deutsch, Bartosz Ludwik, Magdalena Zagrodzka, Lesław Szydłowski, Sebastian Stec,

Patients with structural heart disease (SHD) are more difficult to ablate than those with a structurally healthy heart. The reason may be technical problems. We compared periprocedural data in unselected patients (including SHD group) recruited for zero-fluoroscopy catheter ablation (ZF-CA) of supraventricular arrhythmias (SVTs).Consecutive adult patients with atrioventricular nodal reentry ...

Risk of left atrial appendage thrombus in patients scheduled for ablation for atrial fibrillation: beyond the CHA2DS2VASc score.

Agnieszka Sikorska, Jakub Baran, Ewa Pilichowska-Paszkiet, Małgorzata Sikora-Frąc, Tomasz Kryński, Roman Piotrowski, Sebastian Stec, Beata Zaborska, Piotr Kułakowski,

INTRODUCTION:Atrial fibrillation (AF) increases the risk of thromboembolic events by promoting clot formation in the left atrial appendage (LAA). Transesophageal echocardiography (TEE) is routinely used to exclude the presence of an LAA thrombus before AF ablation. So far, it has not been established what is the optimal combination of noninvasive ... Read more >>
