Abstract
Continuous monitoring of cardiac rhythm may play an important role in measuring the true symptomatic/asymptomatic atrial fibrillation (AF) burden and improve the management of anti-arrhythmic and anti-thrombotic therapies. Forty-seven patients with mitral valve disease and longstanding persistent AF (LSPAF) underwent a left atrial maze procedure with bipolar radiofrequency and valve surgery. The follow-up data recorded by an implanted loop recorder were analysed after 3, 6 and 12 months. On discharge, 40 (85.1%) patients were in stable sinus rhythm, as documented by in-office electrocardiography (ECG), 4 (8.5%) were in pacemaker rhythm and 3 (6.4%) were in AF. One (2.1%) patient died after 7 months. On 12-month follow-up examination, 30 (65.2%) patients had an AF burden 0.5%. Two (4.3%) patients with AF recurrences were completely asymptomatic. Among the symptomatic events stored by the patients, only 27.6% was confirmed as genuine AF recurrences according to the concomitant ECG recorded by the implanted loop recorder. A concomitant bipolar maze procedure during mitral valve surgery is effective in treating AF, as proved by detailed 1-year continuous monitoring.

Abstract
The efficacy of concomitant ablation techniques in patients with paroxysmal atrial fibrillation (AF) undergoing mitral valve surgery remains under debate. The aim of this prospective, randomized, single-centre study was to compare pulmonary vein isolation (PVI) only versus a left atrial maze (LAM) procedure in patients with paroxysmal AF during mitral valve surgery.
Between February 2009 and June 2011, 52 patients with a mean age of 54.2 (standard deviation 7.2 years) underwent mitral valve surgery and concomitant bipolar radiofrequency ablation for paroxysmal AF. Patients were randomized into the PVI group (n = 27) and the LAM group (n = 25). After surgery, an implantable loop recorder for continuous electrocardiography (ECG) monitoring was implanted. Patients with an AF burden (AF%) of

Abstract
We report our experience with a modified mini-maze procedure and pulmonary vein isolation using radiofrequency energy for treating persistent atrial fibrillation during coronary artery bypass grafting (CABG).
Ninety-five patients with persistent atrial fibrillation and coronary heart disease underwent open heart surgery combined with intraoperative irrigated radiofrequency ablation. Patients were randomized into the following three groups: CABG and irrigated radiofrequency pulmonary vein isolation (CABG+PVI, n = 31); CABG and an irrigated radiofrequency modified mini-maze procedure (CABG+MM, n = 30); and isolated CABG (CABG alone, n = 34). All patients received implantable loop recorders.
No reoperation and no hospital mortality were recorded. Mean follow-up was 14.4 ± 9.7 months. The implantable loop recorder-determined freedom from atrial fibrillation was 80% in the CABG+PVI group, 86.2% in the CABG+MM group and 44.1% in the CABG alone group.
Patients with concomitant atrial fibrillation and coronary heart disease may benefit from intraoperative ablation to prevent relapse of arrhythmia.

Abstract
Most studies have confirmed the beneficial effects of autologous bone marrow mononuclear cell (BMMC) transplantation on angina, myocardial perfusion, regional wall motion, and LV ejection fraction (LVEF). Cardiac resynchronization therapy (CRT) has also shown a beneficial effect in patients with heart failure (HF) and electrical/mechanical dyssynchrony. However, the relative contribution of BMMC and CRT in patients with ischemic HF and electromechanical dyssynchrony has never been investigated. The aim of this study was to evaluate the benefit of combining BMMC transplantation with CRT in patients with severe ischemic HF, left bundle branch block (LBBB), and mechanical dyssynchrony. Patients with ischemic HF, LVEF?

Abstract
The aim of this prospective randomized study was to assess whether an early reablation was superior to antiarrhythmic drug (AAD) therapy in patients with previous failed pulmonary vein isolation.
Patients with paroxysmal atrial fibrillation (AF) eligible for AAD therapy or reablation after a previously failed initial pulmonary vein isolation procedure were eligible for this study and were followed up for 3 years to assess rhythm by means of an implanted cardiac monitor. After the blanking period postablation, 154 patients had symptomatic AF recurrences and were randomized to AAD (n=77) or repulmonary vein isolation (n=77). At the end of follow-up, 61 (79%) patients in the AAD group and 19 (25%) patients in the reablation group demonstrated AF% progression (P

Abstract
Catheter ablation of atrial fibrillation (AF) has proved effective in curing highly symptomatic patients with paroxysmal AF. The aim of this prospective, randomized study was to identify the optimal treatment of patients with AF recurrences after the first ablation.
Two hundred eighty-six patients with paroxysmal AF underwent ablation (circumferential pulmonary vein isolation with linear lesions) and were monitored with an implantable cardiac monitor (Reveal XT, Medtronic). Patients without AF recurrences during the 3-month postablation period were assigned to group 1; those with AF recurrences to group 2. Patients in group 2 were randomly assigned to group 3 or group 4. Group 3 patients were treated only with antiarrhythmic drugs for 6 weeks, with no early reablation during the 3-month postablation period. In the case of AF recurrence after the 3-month postablation period, patients underwent reablation. Group 4 patients were treated according to the onset mechanism of AF recurrences, as detected and stored by the implantable cardiac monitor: antiarrhythmic drug therapy, but no reablation if AF was not preceded by triggers; early reablation if premature atrial beats or atrial tachycardias or flutter triggered AF. All patients were followed up for 1 year to assess maintenance of sinus rhythm in each group. On 12-month follow-up examination, of the 119 (42%) patients in group 1, 112 (94%) had no AF recurrences. Among the 83 patients in group 3, only 27 (33%) had no recurrences. Of the 84 group 4 patients, 67 (80%) had no AF recurrences (P
