To characterize the nature of atrial fibrillation (AF) activation in human persistent AF (PerAF) using modern tools including activation, directionality analyses, complex-fractionated electrogram, and spectral information. The mechanism PerAF humans is uncertain. High-density epicardial mapping (128 electrodes/6.75 cm2) posterior LA wall (PLAW), RA appendage (LAA, RAA), RSPV-LA junction was performed 18 patients with undergoing open heart surgery. Continuous 10 s recordings were analysed...
Background— The pulmonary vein–left atrial (PV–LA) junction is key in pathogenesis of AF, and acute stretch an important stimulus to AF. We aimed characterize the response stretch, hypothesizing that would result electrophysiological changes predisposing re-entry. Methods Results— Fifteen participants undergoing cardiac surgery underwent evaluation right superior PV–LA using epicardial mapping plaque. In 10, this was performed before after imposed by rapid volume expansion, 5, it with...
The Ross procedure has demonstrated excellent results when performed in patients with aortic stenosis or mixed valve disease [aortic and regurgitation (AR)]. However, due to its reported risk of late reoperation, it is not recommended under current guidelines for presenting bicuspid pure AR. We have analysed our own light this recommendation. Between 1993 2016, 129 consecutive a mean age 34.7 ± 10.6 years (range 16–64 years) presented AR underwent the procedure. Patients were reviewed...
Endocardial-epicardial dissociation and focal breakthroughs in humans with atrial fibrillation (AF) have been recently demonstrated using activation mapping of short 10-second AF segments. In the current study, we used simultaneous endo-epi phase to characterize patterns on long segments human persistent AF.Simultaneous intraoperative endo- epicardial lateral right atrium wall was performed patients 2 high-density grid catheters (16 electrodes, 3 mm spacing). Filtered unipolar bipolar...
Double mitral and aortic mechanical valves present an access challenge when planning a ventricular tachycardia (VT) ablation. In this case report, we describe patient who was considered for stereotactic ablative radiotherapy but unable to proceed due unfavorable anatomy making them at high risk of fistula formation. The went on have endocardial VT ablation via mini-thoracotomy transapical without complication. This highlights the need careful consideration treatment patients with double valves.
