Right ventricular (RV) pacing has been reported to result in ventricular dyssynchrony, heart failure, and increased mortality. Pacing associated deterioration of left ventricular (LV) systolic function has been termed pacing-induced cardiomyopathy (PICM). While upgrading to biventricular pacing (BiVP) is an effective therapy for PICM, permanent His-bundle pacing (HBP) can be a physiological alt...

despite of the fact that the economy has rooted in empirical science, it has been under influence of opinions and religious values. moreover, economical systems who manage leading this science are based on theological and normative principles. today the issue of permanent development conjoint with biological environment and right of aftertime generations, and beside occupying economists mind, e...

Objective: Central venous catheterization (CVC) is a type of surgery that hemodialysis (HD) patients frequently undergo. Presently, permanent CVCs (pCVCs) are the alternative to vascular access for patients requiring long-term catheterization. Additionally, identification of the type of catheter has a great importance for the right intervention. Our study aims: The aim was to discuss the identi...

BACKGROUND Percutaneous transluminal septal myocardial alcohol ablation (PTSMAA) is not a procedure without complications. It may produce heart arrhythmias, especially those due to disturbances of atrioventricular (AV) and interventricular (IV) electrical conduction. OBJECTIVE The goal of this study was to evaluate the relationship between the anatomical patterns of the right coronary artery ...

Permanent cardiac pacing is a method of choice in the treatment of specific arrhythmias and conduction disturbances. Clinical studies show that cardiac performance diminished at the site of impulse spreading. It determines local hypotrophy below the position of the pacing lead (early electric activation) with hypertrophic changes in the opposite lying myocardium (late electric activation). It s...

The aims of the present study were to evaluate the angulation and inclination of permanent maxillary incisors and to correlate the results to the intra-alveolar permanent maxillary canine position during mixed dentition, using cone beam computed tomography (CBCT). The subjects were 30 children aged 7 to 10 years in the inter-transitory period of mixed dentition (permanent incisors and first mol...

OBJECTIVES The aim of this study was to compare--in patients with persistent and permanent atrial fibrillation (AF)--the efficacy and safety of left atrial ablation with that of a biatrial approach. BACKGROUND Left atrium-based catheter ablation of AF, although very effective in the paroxysmal form of the arrhythmia, has an insufficient efficacy in patients with persistent and permanent AF. ...

Complicated crown fracture and crown-root fracture with pulp involvement expose dental pulp to the oral environment. The pulp outcome is often unpredictable because the patient and injury which are related to variables can influence the treatment of choice and the prognosis of the case. This report presents the case of a 4-year-old boy with complicated crown fracture with pulp polyp in the prim...
