Objectives – Non- valvular atrial fibrillation (NVAF) is the most commonly occurring arrhythmia worldwide .Ranolazine is an emerging drug with a ray of hope in the management of NVAF. This is the first large observational study with longer follow up of one year. Methods - It is a hospital based observational prospective study. A total of 100 patients was recruited for the study .The primary objective was to determine the efficacy of ranolazine in converting NVAF to sinus rhythm & the secondary objective was to study epidemiological aspects of NVAF. Results –After 1 month of follow up conversion to normal sinus rhythm was 12% in group A & 6% in group B (6%), it was not significant statistically (Z=1.48p=0.13). After 6 months, conversion to normal sinus rhythm was increased from 12% to 18% in group A which was preserved at 12 months of follow up and statistically significant and higher than that of group B (6.0%) (Z=2.61p=0.009). In predisposing risk factors & other co-morbidities HTN was present in 61%, obesity together with overweight in 37%, smoking in 44%, history of moderate amount of alcohol intake in 35%, history of CVA/TIA in 13%, DM in 11%, CKD in 4%, CAD in 30%, COPD in 20% and congestive heart failure in 15% of the patients. Conclusion- Ranolazine is an effective option when used for rhythm control strategy in NVAF. HTN is the predominant predisposing risk factor.

Background - Bucindolol is a genetically targeted β-blocker/mild vasodilator with the unique pharmacologic properties of sympatholysis and ADRB1 Arg389 receptor inverse agonism. In the GENETIC-AF trial conducted in a genetically defined heart failure (HF) population at high risk for recurrent atrial fibrillation (AF), similar results were observed for bucindolol and metoprolol succinate for the primary endpoint of time to first atrial fibrillation (AF) event; however, AF burden and other rhythm control measures were not analyzed. Methods - The prevalence of ECGs in normal sinus rhythm, AF interventions for rhythm control (cardioversion, ablation and antiarrhythmic drugs), and biomarkers were evaluated in the overall population entering efficacy follow-up (N=257). AF burden was evaluated for 24 weeks in the device substudy (N=67). Results - In 257 patients with HF the mean age was 65.6 ± 10.0 years, 18% were female, mean left ventricular ejection fraction (LVEF) was 36%, and 51% had persistent AF. Cumulative 24-week AF burden was 24.4% (95% CI: 18.5, 30.2) for bucindolol and 36.7% (95% CI: 30.0, 43.5) for metoprolol (33% reduction, p < 0.001). Daily AF burden at the end of follow-up was 15.1% (95% CI: 3.2, 27.0) for bucindolol and 34.7% (95% CI: 17.9, 51.2) for metoprolol (55% reduction, p < 0.001). For the metoprolol and bucindolol respective groups the prevalence of ECGs in normal sinus rhythm was 4.20 and 3.03 events per patient (39% increase in the bucindolol group, p < 0.001), while the rate of AF interventions was 0.56 and 0.82 events per patient (32% reduction for bucindolol, p = 0.011). Reductions in plasma norepinephrine (p = 0.038) and NT-proBNP (p = 0.009) were also observed with bucindolol compared to metoprolol. Conclusions - Compared with metoprolol, bucindolol reduced AF burden, improved maintenance of sinus rhythm, and lowered the need for additional rhythm control interventions in patients with HF and the ADRB1 Arg389Arg genotype.

Abstract Background The severity of tricuspid regurgitation (TR) in patients with restored normal sinus rhythm (SR) after atrial fibrillation (AF) has been poorly assessed. Purpose Our study aimed to assess (1) right chamber remodelling and (2) TR severity in patients with AF who have had their rhythms restored to normal sinus. Methods We prospectively evaluated 94 consecutive patients hospitalized for AF who received either ablation, direct current cardioversion, or pharmacological therapy. Patients were divided into two groups according to their cardiac rhythm at 6 months follow up (6M): restoration to SR (SR group, n=54), persistence of AF (AF group, n=40). TR vena contracta (VC), TR grade severity was divided into 4 grades using an integrated approach (0: none or trace; 1: mild; 2: moderate; 3: severe TR). Two dimensional (2D) end diastolic (ED) tricuspid annulus (TA) diameter in the apical 4 chambers view, three-dimensional (3D) indexed volumes (3D Vi) of the right atrium (RA) and right ventricle (RV) in end systole (ES) and ED were acquired using transthoracic echocardiography at admission and at 6M. Results At 6M, in the SR group a significant improvement in TR VC (Figure A) and TR grade (Figure B) were noted, whereas there was no differences in the AF group (0.41 vs. 0.42cm, p=0.24 for TR VC; 1.70 vs. 1.76, p=0.16 for mean TR grade). In the SR group a significant reduction in 3D ES RV Vi, 2D ED TA diameter, 3D ES and ED Vi of the RA (Table) were observed. Regression of TR VC was correlated with regression of right cavities parameters (ρ=0.47, p&lt;0.001 for 2D ED TA diameter; ρ=0.34, p&lt;0.005 for 3D ES RA Vi; ρ=0.33, p&lt;0.005 for 3D ED RV Vi; ρ=0.29, p&lt;0.005 for 3D ES RV Vi). Conclusion Restoration of normal SR in patients with AF results in beneficial remodelling of right cavities at 6M of follow-up which were associated with a significant decrease in TR severity. Strategies for normal SR restoration in patients with AF and TR should be vigorously attempted. TR Evolution Funding Acknowledgement Type of funding source: None

Background: Atrial Fibrillation (AF) is the most common arrhythmia occurring after cardiac surgery and its peak incidence is between second or third postoperative day. It occurs in 40% to 50% of patients after valve surgery alone or combined valve and CABG surgery respectively. Among all the anti-arrhythmic drugs evaluated for AF, amiodarone has shown the most promising results with successful conversion and maintenance of normal sinus rhythm achieved in 50%–70% of patients. Methods: Sixty diabetic patients purposively selected who underwent isolated off pump coronary artery bypass procedure in NICVD. Group A – 30 patients receiving loading dose of amiodarone intra-operatively before establishment of CPB during valve replacement surgery and Group B- 30 patients without receiving loading dose of amiodarone intra-operatively during valve replacement surgery. Incidence of atrial fibrillation in postoperative period was evaluated. Results: Atrial fibrillation was observed in 8 (26.7%) patients in group A and 18 (60%) patients in group B (p=0.009). Ventricular tachycardia developed in 6.7% patients in group B and none in group A (p=0.47). Mean duration of ICU stay was 2.04±0.30 days in Group A and Group B was 2.98±0.77 days (p=0.03). Mean duration of post-operative stay was 7.20±0.66 days in Group A and Group B was 7.85±0.60 days (p=0.10). Conclusion: A single intra operative dose of intravenous amiodarone increases the incidence of conversion of AF to normal sinus rhythm. When AF persisted, use of amiodarone reduces the frequency of need for cardioversion and the energy required for it. Cardiovasc. j. 2020; 12(2): 102-108

<p><b>Background:</b> Adequate exposure of the mitral valve is a critical factor of success for either replacement or repair of the mitral valve. In the present study, we evaluated the merits of the extended vertical transseptal approach in comparison with the transseptal approach for mitral valve operations.</p><p><b>Methods:</b> A total of 72 consecutive patients operated on for mitral procedures were allocated to either group A (those operated on through an extended vertical transseptal approach [n = 38]) or group B (whose mitral valve exposure was achieved through a right atrium transseptal approach [n = 34]). The operation time, aortic cross-clamp time, first 24-hour drainage volume after the operation, and the rhythms pre- and postsurgery were compared between the 2 groups.</p><p><b>Results:</b> The mean operation time and mean cross-clamp time in group A were longer than that in group B and the drainage volume was greater in the first 24 hours, but the differences were not statistically significant. There was no surgical reexploration for bleeding in either group. For the 13 patients who had normal sinus rhythm preoperatively in group A, 2 (15.4%) developed episodes of atrial fibrillation and 1 (7.7%) developed temporary sinus bradycardia requiring temporary pacing in the immediate and early postoperative period. In group B, 2(15.4%) of patients with normal sinus rhythm before surgery developed atrial fibrillation that continued until 1 week after surgery.</p><p><b>Conclusion:</b> The extended vertical transseptal approach not only affords excellent exposure of the mitral valve, but also is safe for maintaining sinus node function compared with the transseptal approach.</p>

Background: Heart failure (HF) is the leading cause of death in patients with atrial fibrillation (AF). Radiofrequency catheter ablation (RFCA) of AF is effective for maintaining sinus rhythm though its impact on heart failure still remains controversial. Purpose: We sought to elucidate whether AF recurrence following RFCA was associated with subsequent HF hospitalizations. Methods: We conducted a large-scale, prospective, multicenter, observational study. A total of 4931 consecutive patients who underwent an initial RFCA for AF with longer than 1-year of follow-up in 26 centers were enrolled (average age, 64±10 years; non-paroxysmal AF, 35.7%). The median follow-up duration was 2.9 years. The primary endpoint was an HF hospitalization more than 1-year after the index RFCA. We compared the patients without AF recurrences (group A) to those with AF recurrences within 1-year post RFCA (group B). Results: The 1-year cumulative incidence of AF recurrences after a single procedure was 30.7% (group A=3418, group B=1513 patients). Group B had a lower body mass index (group A vs. group B,24.1±3.6 vs. 23.8±3.4 kg/m 2 , p=0.014), longer history of AF (1.9 vs. 3.1 years, p<0.0001), higher prevalence of non-paroxysmal AF (32.1% vs. 33.9%, p<0.0001), and valvular heart disease (5.9% vs. 7.8%, p=0.013). They also had a lower ejection fraction (63.7±9.4% vs. 62.8±9.6%, p=0.0043) and larger left atrial dimeter (39.7±6.6 vs. 40.6±7.0 mm, p<0.0001) on echocardiography. Hospitalizations for HF were observed in 57 patients (1.14%) more than 1-year after the RFCA and were significantly higher in group B than group A (group A vs. group B, 0.91% vs 1.72%, log-rank p=0.019). Conclusions: Among AF patients receiving RFCA, those with AF recurrences were at a greater risk of subsequent heart failure hospitalizations than those without AF recurrences. Recognition that AF recurrence following RFCA is a risk factor for a subsequent HF-related hospitalization is appropriate in clinical practice.

Abstract Background Percutaneous left atrial appendage (LAA) closure is an alternative to oral anticoagulation (OAC) for atrial fibrillation (AF) patients with high thromboembolism risk, particularly with contraindications to OAC. The LAA itself could possess proarrhythmogenic properties. As patients undergoing LAA closure could be candidates for cardioversion or ablation, we aimed to evaluate AF disease progression following LAA closure and the outcome of patients undergoing a rhythm control strategy after the procedure. Methods The prospective multicenter French Nationwide Observational LAA Closure Registry (FLAAC) comprises 33 French interventional cardiology departments. Patients were included if they fulfilled the following criteria: history of non-valvular AF, successful LAA closure and long-term ECG follow-up. Results A total of 331 patients with successful LAA closure were enrolled in the study. Patients mean age was 75.4 ± 0.5 years. The study population was characterized by a high thromboembolic risk (CHA2DS2-VASc score: 4.5 ± 0.1) and frequent comorbidities. The median follow-up was 11.9 months. One hundred and nineteen (36.0%) patients were in sinus rhythm (SR) at baseline. Among SR patients, documented AF was observed in 16 (13.4%) patients whereas 15 (7.1%) patients in AF at baseline restored SR, at the end of follow up. Finally, only 13 patients (4%) underwent procedures to restore SR without complications during the follow-up. Conclusions The vast majority of patients undergoing LAA closure have the same AF status at baseline and one year after the index procedure. During the follow-up, a very small proportion (4%) of our population underwent procedures to restore SR without complications whatever the post-procedural antithrombotic strategy was.

Background: Atrial fibrillation (AF) is an established risk factor for ischemic stroke, but it can be paroxysmal and may go undiagnosed. An artificial intelligence (AI)-enabled ECG acquired during normal sinus rhythm was recently shown to detect silent AF. The objective of this study was to determine if AI-ECG AF score is associated with presence of cerebral infarcts. Methods: Participants from a population-based study ages 30 to 95 years with T2 fluid attenuation inversion recovery (FLAIR) MRI obtained between October 10, 2011, and November 2, 2017 were considered for inclusion. Participants without ECG were excluded. AI-ECG score was calculated using most recent ECG with normal sinus rhythm at the time of MRI. Presence of infarcts was determined on FLAIR MRI scans. Logistic regression was run to evaluate the relationship between AI-ECG AF score and presence of cerebral infarcts. Similar analyses were performed using history of AF rather than AI-ECG AF score as predictor. Age and sex were included as covariates. We also examined whether a high-threshold AI-ECG score was associated with infarcts. In a prior study, an AI-ECG AF score > 0.5 was associated with a cumulative incidence of AF of 21.5% at 2 years and 52.2% at 10 years. Results: This study included 1,373 individuals. Average age was 69.6 years and 53% of participants were male. There were 136 (10%) individuals with ECG-confirmed AF; 1237 (90%) participants had no AF history. Of participants with AF, 23% (n=31) were on anticoagulation, 47% (n=64) were on antiplatelet and 18% (n=24) were on dual therapy. Only 1.3% (n=16) of patients without AF were on anticoagulation and 47% (n=578) were on antiplatelet therapy. Ischemic infarcts were detected in 214 (15.6%) patients. As a continuous measure AI-ECG was associated with infarcts but not after adjusting for age and sex (p=0.46). AI-ECG AF score > 0.5 was associated with infarcts ( p < 0.001); even after adjusting for age and sex ( p = 0.03). History of AF was also associated with infarcts after adjusting for age and sex ( p = 0.018). Conclusion: AI-ECG AF score and history of AF were associated with presence of cerebral infarcts after adjusting for age and sex. This tool could be useful in select patients with cryptogenic stroke but further investigation would be required.

Purpose: To compare the efficacy of two different suture types in levator plication for correction of congenital ptosis. Subjects and methods: Prospective comparative interventional randomized study involving 42 eyes of 42 patients aged more than 6 years with congenital ptosis and good levator action. The exclusion criteria were as follows: bilateral ptosis, history of previous surgery, fair or poor levator action, and associated other ocular diseases. Patients were randomized into group A, in which double-armed 5/0 polyester Ethibond were used, and group B, in which double-armed 5/0 Coated Vicryl® (polyglactin 910) suture material we used. Outcomes including eyelid height and stability of eyelid height over time were compared with follow-up data. The MRD was 4.05 ± 0.36 mm and 3.95 ± 0.34 after 1 week for both groups A and B, respectively. At the end of study follow up period (24 weeks), the MRD was 3.60 ± 0.42 mm in group A, and 2.52 ± 0.85 mm in group B. Conclusion: No difference in eyelid height between two groups in early postoperative period, but the postoperative eyelid height was more stable over time in the 5/0 polyester Ethibond group (group A) than in the 5/0 Coated Vicryl® (polyglactin 910) group (group B).
