John Somberg Md, Janos Molnar Md
The availability of intravenous (IV) Sotalol has equalized the treatment options since both amiodarone and sotalol are available in both IV and oral formulations. A review of the efficacy of sotalol as compared to amiodarone both for conversion of atrial fibrillation (AF) and maintenance of normal sinus rhythm (NSR) following cardiac surgery was undertaken. Standard methods of meta-analysis were employed. Full text publications of clinical trials written in English that compared the efficacy of sotalol to amiodarone were included in the analysis...

Silent brain lesions due to thrombogenicity of the procedure represent recognized side effects of atrial fibrillation (AF) catheter ablation. Embolic risk is higher if anticoagulation is inadequate and recent studies suggest that uninterrupted anticoagulation, ACT levels above 300 seconds and administration of a pre-transeptal bolus of heparin might significantly reduce the incidence of silent cerebral ischemia (SCI) to 2%. Asymptomatic new lesions during AF ablation should suggest worse neuropsychological outcome as a result of the association between silent cerebral infarcts and increased long-term risk of dementia in non-ablated AF patients...

BACKGROUND: Surgical experience with chronic constrictive pericarditis (CCP) is rarely documented in Africa; the aim of this study is therefore to review our African experience with CCP from 1977 to 2012 in terms of clinical and surgical outcomes and risk factors of early death after pericardiectomy. METHODS: This retrospective study is related to 120 patients with CCP; there were 72 men and 48 women with an average age at 28.8±10.4 years standard deviation (SD) (8-51 years)...

: Knowledge of the mechanism underlying post-operative atrial fibrillation (PoAF) is essential for development of preventive measures. The incidence and characteristics of both PoAF and supraventricular premature beats triggering PoAF, their interrelationship and alterations over time have never been examined. The goal of this study is therefore to examine the correlation between the incidence and characteristics of supraventricular premature beats (SVPBs) and PoAF episodes in patients undergoing CABG in the first five post-operative days...

BACKGROUND: Transcatheter aortic valve implantation (TAVI) has been adopted worldwide as the standard treatment for severe aortic stenosis in symptomatic patients at prohibitive or high surgical risk, but there are still several areas where consensus and evidence are lacking. The purpose was to obtain a global view of current practice related to TAVI with the potential to identify the main areas of consensus and divergence between centers. METHODS: An online questionnaire was distributed in centers performing TAVI including a total of 59 questions concerning pre-procedural evaluation, procedural practices and post-procedural management...

BACKGROUND: Amiodarone frequently is used in patients with heart failure. Concerns still exist about possible complications related to its lingering effect during and after heart transplantation. METHODS: We selected all consecutive patients who received a heart transplant at our institution between January 2004 and December 2015 (n = 220) and compared the peri- and postoperative outcomes of patients who were taking amiodarone for at least 120 days before heart transplant (n = 127) with patients who did not take amiodarone prior to heart transplant (n = 93)...

BACKGROUND: Paroxysmal atrial fibrillation (PAF) can increase thrombogenesis risk, especially in the left atrium (LA). The exact mechanism is still unclear. OBJECTIVE: We assessed the effects of PAF on endothelial function, and investigated if febuxostat (FX) can attenuate endothelial dysfunction by inhibition of xanthine oxidase (XO). MATERIALS AND METHODS: Eighteen male New Zealand white rabbits were divided randomly into sham-operated (S), PAF (P) or FX+pacing (FP) groups...

BACKGROUND: Severe primary mitral regurgitation (MR) carries a significant incidence of mortality and morbidity. Though a number of prognostic factors have been identified, the best timing for mitral valve repair is still debated. We assessed the role of Left Atrial Volume Indexed (LAVI) as predictor of adverse events after mitral valve surgery. METHODS: 134 patients with severe MR were studied with a follow-up of 42±16months. Endpoints were Post-Operative Atrial Fibrillation (POAF), atrial and ventricular remodeling (LARR/LVRR) and correlation with outcome...

AIM: To study whether remote ischemic preconditioning (RIPC) has an impact on clinical outcomes, such as post-operative atrial fibrillation (POAF). METHODS: This was a prospective, single-center, single-blinded, randomized controlled study. One hundred and two patients were randomized to receive RIPC (3 cycles of 5 min ischemia and 5 min reperfusion in the upper arm after induction of anesthesia) or no RIPC (control). Primary outcome was POAF lasting for five minutes or longer during the first seven days after surgery...

The aim of the present study was to confirm the effect of Tanshinone IIA (TAN) on the prevention of AF in chronic heart failure (CHF), and to elucidate the underlying electrophysiological mechanisms for the antiarrhythmic effects of TAN at the level of the atrium in an experimental model of CHF. In 10 female rabbits, CHF was induced by rapid ventricular pacing, leading to a significant decrease in ejection fraction in the presence of a dilated left ventricle and atrial enlargement. Twelve rabbits were sham-operated and served as controls...

BACKGROUND: Left atrial appendage closure (LAAC) using the Watchman device was FDA-approved as a stroke prevention alternative to warfarin for patients with non-valvular atrial fibrillation. However, clinical decision-making is confounded by the fact that while LAAC avoids the anticoagulant-related lifetime risk of bleeding, implantation is associated with up-front complications. Thus, enthusiasm for LAAC as a treatment option has been appropriately tempered, particularly as the therapy is introduced beyond the clinical trial sites into general clinical practice...

BACKGROUND: During atrial fibrillation (AF), a high rate of myocyte activation causes cellular stress and initiates the process of atrial remodeling, which further promotes persistence of AF. Although heat shock proteins (HSPs) have been shown to prevent atrial remodeling and suppress the occurrence of AF in cellular and animal experimental models, increased levels of HSP-60 have been observed in patients with postoperative AF, likely reflecting a response to cellular stress. To better understand the role of HSP-60 in relation to AF, we examined the association of HSP-60 levels in relation to the future development of AF in the Multi-Ethnic Study of Atherosclerosis (MESA)...

BACKGROUND: New-onset atrial fibrillation (AF) after coronary artery bypass graft surgery (CABG) is associated with increased morbidity and poorer long-term survival. Although many studies show differences in outcome in women versus men after CABG, little is known about the sex-specific incidence and characteristics of post-CABG AF. METHODS AND RESULTS: Overall, 11 236 consecutive patients without preoperative AF underwent isolated CABG from 2002 to 2010 at 4 US academic medical centers and 1 high-volume specialty cardiac hospital...

BACKGROUND: Current real-life information from all-comers registries from middle and east Europe about the incidence and type of complications during long-term follow-up of patients with cardioverters-defibrillators (ICD) and cardiac resynchronization devices-defibrillators (CRT-D) is still insufficient. The aim of the study was to assess the incidence and determinants of short- and long-term complications related to implantable ICD and CRT-D. METHODS: We studied 1,105 recipients hospitalized in our center in 2009-2013, followed for a mean of 2...

Atrial volumes indexed to body surface area (AVI) are robust predictors of nonvalvular atrial fibrillation (AF) recurrence after direct current cardioversion (DCCV). The incremental value of atrial emptying fraction (EmF) compared with atrial volumes as a predictor for recurrent AF after DCCV has not been evaluated. We sought to compare the predictive ability of baseline left atrial (LA) EmF, right atrial (RA) EmF, LAVI, and RAVI for post-DCCV AF recurrence at 6 months. The first 95 patients enrolled in the AF Clinic Registry with adequate echocardiogram imaging constituted the study cohort...

OBJECTIVE: Atrial fibrillation is the most common arrhythmia after cardiac surgery. Several studies have shown the impact of vitamin D on heart disease; however, there have been few studies for the incidence of AF and its relationship with vitamin D levels. According to the different results of these studies, we decided to evaluate the relation of plasma levels of vitamin D and postoperative atrial fibrillation in patients undergoing coronary artery bypass surgery (CABG). METHODS: This cross-sectional study was performed on 50 patients after CABG surgery...

Magnesium is the fourth most abundant cation in the human body and is the second most prevalent cation in intracellular tissues. Myocardial cell action potentials are mediated by voltage-dependent Na(+), K(+), and Ca(2+ )channels which, when their function is altered, can lead to the genesis of cardiac dysrythmias. Magnesium regulates the movement of ions through these channels within myocardial tissues. The potential ability of magnesium supplementation to prevent and/or treat arrhythmias has been recognized in clinical medicine for years...
