Background: Hypomagnesemia is a known predisposing condition for the appearance of digitalis toxicity. The detection of a genetic form of Mg urinary wasting with hypomagnesemia being caused by a mutation in the γ subunit (FXYD2) of the Na,K-ATPase, the pharmacological target of Digoxin, prompted us to investigate whether Digoxin administration increases urinary Mg excretion. Methods: Two groups of subjects, with rapid atrial fibrillation, received intravenous Digoxin (n = 9) or verapamil (n = 8), for heart rate control...

REVIEW
Safi U Khan, Ahmad N Lone, Muhammad A Saleem, Edo Kaluski
The American and European expert documents recommend transcatheter aortic valve replacement (TAVR) for inoperable or high-surgical-risk patients with severe aortic stenosis. In comparison, efficacy of TAVR is relatively less studied in low- to intermediate-surgical-risk patients. We sought to discover whether TAVR can be as effective as surgical aortic valve replacement (SAVR) in low- to intermediate-surgical-risk candidates. Four randomized clinical trials (RCTs) and 8 prospective matched studies were selected using PubMed/MEDLINE, Embase, and Cochrane Library (inception: March 2017)...

A patient presented with symptoms of decompensated heart failure 2 months after percutaneous mitral valve (MV) repair. Echocardiography demonstrated impaired left ventricular function with elevated MV pressure gradients and pulmonary pressures during rapid atrial fibrillation. Heart rate control was achieved by implantation of a biventricular pacemaker with subsequent His-bundle ablation because atrial fibrillation was refractory to medical treatment. During biventricular pacing at different rates (50-110 b...

BACKGROUND: Post-operative atrial fibrillation (POAF) is the most common cardiac arrhythmia occurring after coronary artery bypass grafting (CABG). Arrhythmia leads to prolonged hospitalization and may have impact on both short-term and long-term prognoses. AIM: The aim of this paper was the evaluation of the incidence of POAF in patients after CABG as well as the identification of its predictors. METHODS: The study was performed on 791 patients (selected from a group of 1031 patients who underwent CABG in the Clinical Department of Cardiology in years 2009-2011) who did not suffer from atrial fibrillation (AF) prior to isolated CABG...

Yanjing Wang, Chi Wu
The fibrillation of misfolded neurodegenerative diseases related proteins has been extensively studied in the last few decades, but the initial oligomerization has been rarely touched even though some recent evidences indicated that small protein oligomers are more neurotoxic than long protein fibers. It is rather difficult to study the initial oligomerization (nucleation) because most of experimental methods, such as β-sheet related fluorescence assay and X-ray diffraction, are helpless in detecting small structure-less protein oligomers...

Background: Obstructive sleep apnea (OSA) is common in heart failure (HF) patients and exacerbates the outcome of this chronic disease. However, the frequency of HF arising from OSA is varied, with little supporting literature. Here, we aimed to clarify the incidence risk of HF and major adverse cardiac events (MACEs) in OSA patients from the Taiwan large database. Methods and Results: From 2000-2010, a total of 2699 newly diagnosed OSA patients after polysomnographic study and 13,490 non-OSA patients utilizing 1:5 matching was enrolled and followed to 2011...

Patients with short QT syndrome (SQTS) may present with syncope, ventricular fibrillation or sudden cardiac death. Six SQTS susceptibility genes, encoding cation channels, explain <25% of SQTS cases. Here we identify a missense mutation in the anion exchanger (AE3)-encoding SLC4A3 gene in two unrelated families with SQTS. The mutation causes reduced surface expression of AE3 and reduced membrane bicarbonate transport. Slc4a3 knockdown in zebrafish causes increased cardiac pHi, short QTc, and reduced systolic duration, which is rescued by wildtype but not mutated SLC4A3...

Aims: In the Far East, there has generally been low uptake of oral anticoagulants (OACs) using vitamin K antagonists (VKA, e.g. warfarin) for stroke prevention in atrial fibrillation (AF), but OAC use has been increasing more recently, with the introduction of the non-vitamin K antagonist oral anticoagulants (NOACs). To explore the risks of ischaemic stroke (IS) and death related to AF in East Asia using modelling projections. Methods and results: We performed a modelling analysis of possible trends of IS and death rates in AF patients from the time period of only VKA use to current increasing trends of NOAC use projecting until 2050 in East Asia...

Aims: Electrical cardioversion (ECV) is frequently required for early atrial fibrillation (AF) recurrence after catheter ablation. However, in some cases, ECV is unsuccessful, and factors associated with long-term rhythm outcomes after failed ECV are unknown. This study aimed to identify possible predictors of ECV failure early after AF ablation and to analyse management and long-term rhythm outcome of these patients. Methods and results: Between 2010 and 2012, 180 consecutive patients (mean age 63...
