Does the same lesion index mean the same efficacy and safety profile: influence of the differential power, time, and contact force on the lesion size and steam pops under the same lesion index
The lesion index (LSI) helps predict the lesion size and is widely used in ablation of various types of arrhythmias. However, the influence of the ablation settings on the lesion formation and incidence of ste...

Open AccessAge-dependent contribution of intrinsic mechanisms to sinoatrial node function in humans
Average beat interval (BI) and beat interval variability (BIV) are primarily determined by mutual entrainment between the autonomic-nervous system (ANS) and intrinsic mechanisms that govern sinoatrial node (SA...

Initial multicenter clinical experience with the first-generation endoscopic guided laser balloon in Japan
Isolation of the pulmonary veins (PVs) is the golden standard for atrial fibrillation (AF) ablation. To achieve a permanent PV isolation, the endoscopic guided HeartLight laser balloon system was invented. We ...

Open AccessImpact of long-term optimizing atrioventricular delay using device-based algorithms on cardiac resynchronization therapy
Sub-optimal atrioventricular delay (AVD) is one of the main causes of non-responder for cardiac resynchronization therapy (CRT). Recently, device-based algorithms (DBAs) that provide optimal AVD based on intra...

Open AccessPlacebo-Controlled, Double-Blind Study of Empagliflozin (EMPA) and Implantable Cardioverter-Defibrillator (EMPA-ICD) in Patients with Type 2 Diabetes (T2DM): Rationale and Design
Type 2 diabetes (T2DM) is associated with cardiovascular death, including sudden cardiac death due to arrhythmias. Patients with an implantable cardioverter-defibrillator (ICD) are also at high risk of develop...

Open AccessEffect of cardiovascular risk factors and time of hospital presentation on mortality of maintenance hemodialysis patients presenting with acute pulmonary edema
Acute pulmonary edema (APE) has a poor prognosis in the general population. Mortality associated with APE in patients with end-stage renal disease (ESRD) is especially high, although specific predictors are no...

Prediction of improvement in left atrial function index after catheter ablation for atrial fibrillation
Although left atrial function index is reportedly a possible predictor of hospitalization for heart failure and of stroke irrespective of the presence or not of atrial fibrillation (AF), the effects of cathete...

Catheter ablation for atrial fibrillation results in greater improvement in cardiac function in patients with low versus normal left ventricular ejection fraction
It is still unknown whether left ventricular ejection fraction (LVEF) might affect the magnitude of improvement after atrial fibrillation (AF) ablation on cardiac function in persistent or longstanding persist...
