Comparation of TS and RA approach in ALPM-VA ablation. Via the RA approach the catheter must contact the ALPM with a sharp angle, whereas the TS approach reaches it in parallel with less likelihood of causing bumping, with improved acute success and less need to cross over to a RA approach. TS=transteptal; RA=retrograde aortic; AO=aorta; ALPM=anterior lateral papillary muscle; MA=mitral annulus; LV=left ventricle.

In a single-center study of 102 patients, we demonstrate that the LockeT is a simple yet effective external compression device for venous access closure; almost all patients achieve hemostasis by 2 h.

Following surgical MV repair, early postoperative atrial arrhythmias carried a different prognosis in terms of clinical results and the risk of arrhythmia recurrence based on the type and duration of the postoperative arrhythmia.

Predictors of cardiac neuromodulation during thermal balloon-based ablation for atrial fibrillation. Left panel shows an illustration of the two thermal balloon-based ablation catheters used and the location of the right anterior ganglionated plexus (RAGP) in relation to the left atrium. Right panel presents the independent predictors found for significant heart rate (HR) increase and illustrative examples of the anatomic variable on axial computed tomography images placed at the level of the right superior pulmonary vein (RSPV) with visualization of the balloon catheter and RAGP. The distance between RSPV and superior vena cava (SVC) is illustrated with the red boxes. CB, cryoballoon; HR, heart rate; RF, radiofrequency; RSPV, right superior pulmonary vein; SVC, superior vena cava.
