PURPOSE We hypothesized that pulmonary vein (PV) orientation influences tissue contact of the contact force (CF) sensing radiofrequency ablation catheter (CFC) and therefore atrial fibrillation (AF) free survival after pulmonary vein isolation (PVI). The aim of this study was to determine the association between PV orientation, CF and AF free survival in patients undergoing CFC PVI. METHODS S...

OBJECTIVE To observe the change of PVI after thoracic epidural block on the basis of general anesthesia. METHODS In 26 patients undergoing elective upper abdominal operations, changes of SVI, PVI, SVV, PPV and CVP were monitored immediately before and 10 minutes after T8-9 thoracic epidural anesthesia on the basis of general anesthesia. The definition was that patients with ΔSVI greater than ...

Xanthan gum (XG) is natural polysaccharides used in food industries as stabilizers and thickener agents. The problem is that some food products are found to be contaminated by pathogenic bacteria such as Escherichia coli (E. coli) and Staphyloccus aureus (S. aureus) that reduce their shelf life. This research aims to synthesize biodegradable antibacterial XG-grafted-poly(N-vinyl imidazole) PVI ...

A trial fibrillation is the most common sustained arrhythmia worldwide (1), and catheter-based pulmonary vein isolation (PVI) is becoming a dominant approach to its management. Stroke and transient ischemic attack are known risks of PVI (2). To improve PVI safety, atrial thrombus needs to be excluded. Traditionally, patients undergo elective computed tomography angiography or magnetic resonance...

SEE PAGE 259 I n contrast to coronary artery disease in which a robust collection of data has demonstrated the merits of percutaneous revascularization, research investigating peripheral vascular intervention (PVI) has not yet matured in terms of magnitude, quality, or clarity. For example, only 1 randomized trial has assessed the efficacy of PVI relative to surgical bypass in patients with cri...

BACKGROUND Cerebral perfusion pressure management (CPPM) is an accepted modality of treatment of severe diffuse head injury (SDHI). However, CPPM has the potential to cause transcapillary exudation in the presence of a disrupted blood brain barrier and can lead to further increase of intracranial pressure (ICP) and worsening of compliance. AIMS This study attempts to evaluate the effect of bo...

BACKGROUND The incidence, risk factors, and outcomes associated with Contrast-induced nephropathy (CIN) after Percutaneous Vascular Intervention (PVI) in contemporary medical practice are largely unknown. METHODS A total of 13 126 patients undergoing PVI were included in the analysis. CIN was defined as an increase in serum creatinine from pre-PVI baseline to post-PVI peak Cr of ≥0.5 mg/dL. ...

BACKGROUND Pleth variability index (PVI) is a new algorithm allowing automated and continuous monitoring of respiratory variations in the pulse oximetry plethysmographic waveform amplitude. PVI can predict fluid responsiveness noninvasively in mechanically ventilated patients during general anesthesia. We hypothesized that PVI could predict the hemodynamic effects of 10 cm H2O positive end-expi...

OBJECTIVES We sought to investigate the imaging of the left atrial (LA) muscular bundle and the relationship between the bundle and inducibility of tachyarrhythmia after pulmonary vein isolation (PVI). BACKGROUND Noninducibility is used as a clinical end point of atrial substrate ablation after PVI. However, little is known about the role of the LA muscular bundles in tachyarrhythmia after PV...

INTRODUCTION Plethysmographic Variability Index (PVI) has been shown to accurately predict responsiveness to fluid loads in adults. The goal of this study was to evaluate PVI accuracy when predicting fluid responsiveness during noncardiac surgery in children. MATERIAL AND METHODS Children aged 2-10 years scheduled for noncardiac surgery under general anesthesia were included. PVI was assessed...
