Background Postoperative atrial fibrillation (POAF) is common after cardiac surgery, but little known about its incidence and natural course noncardiac surgery. We evaluated the clinical impact of POAF long-term anticoagulation therapy in patients without a history (AF) undergoing Methods Results retrospectively analyzed database Asan Medical Center (Seoul, Korea) to identify who developed new-onset surgery between January 2006 2016. The main outcomes were AF recurrence, thromboembolic...
<b>Background and study aims:</b> Following noncurative endoscopic resection of early gastric cancer (EGC), the patient should be observed when underlying disease is severe, elderly, or refuses further treatment. The aim this was to analyze clinical outcomes patients with differentiated EGC who underwent without additional <b>Patients methods:</b> Included for treatment at Asan Medical Center between July 1994 January 2009. Clinical oncological were analyzed. <b>Results:</b> A total 159...
Concomitant use of rivaroxaban with non-dihydropyridine calcium channel blockers (non-DHPs) might lead to an increase systemic exposure and anticoagulant effects in relation the inhibition metabolic enzymes and/or transporters by non-DHPs. This study was designed evaluate verapamil diltiazem on pharmacokinetics prolongation prothrombin time rats. The data were analyzed using a pharmacokinetic/pharmacodynamics (PK/PD) modeling approach quantify influence verapamil. Verapamil increased...
Background and objectives Data regarding the safety of atrial fibrillation (AF) ablation using high-power (50 W) radiofrequency (RF) energy in Asian populations are limited. This study was conducted to evaluate incidence pattern esophageal injury after AF an cohort. Methods We searched prospective registry identify patients who underwent with 50 W RF smart touch surround flow catheter (Biosense Webster, Diamond Bar, CA, USA). Visitag™ Webster) used for lesion annotation predefined settings...
최근 글로벌 금융위기와 중소기업들의 연이은 도산으로 인해 국내 구조조정에 대한 논의가 활발히 진행되고 있다. 이에 본 논문에서는 신용보증기금에 등록된 중소기업 자료에 대하여 업종별 생존율 동향을 비교분석하였다. 이때 생존율의 차이는 로그순위 검정과 윌콕슨의 검정통계량을 사용하여 분석하였다. 또한 재무변수들을 이용하여 중소기업의 콕스 회귀분석을 실시하였다. 그 결과, 도소매업과 서비스업이 경공업과 중공업, 건설업에 비하여 생존율이 높았으며, 건설업의 경우 가장 낮음을 알 수 있었다. 또한, 업종별로 유의한 재무변수를 살펴보면, 건설업은 자기자본비율, 유동비율이 커질수록 부도율이 감소하는 반면에 차입금의존도가 증가하였다. 경공업은 총자산 순이익률이 커질수록, 도소매업은 감소하였다. 중공업은 순이익률, 감소하였지만 결합지표가 마지막으로, 서비스업은 Global crisis expedites the change in environment of industry and puts...
Hematoma is quite a common complication of femoral arterial catheterization. However, to the best our knowledge, there have been no previous studies regarding deep vein thrombosis (DVT) caused by compression due hematoma. We report case hematoma developing after catheterization and causing extensive symptomatic DVT. A 59-year-old male was seen in Emergency Department with right lower leg swelling 15 days coronary stent implantation performed using artery access. Computed tomographic (CT)...
This paper presents a manipulator visual servoing algorithm with the Kalman filter. The objective is to control relative position and orientation between robot's gripper an object using single camera mounted on manipulator. feature-based used, which continually updates pose of robot by differential changes in image plane. But acquired from often has several noise elements such as signal spatial quantization error, lens distortion, pixel error etc. In order reduce measurement errors, Filter...
Background Severe conduction delay and inter/intra-atrial dissociation may occur in patients who undergo an extensive catheter ablation or a maze procedure for atrial tachyarrhythmia. We report series of with that mimicked complete atrioventricular block ventricular tachycardia. Methods Results retrospectively reviewed the medical records 7 were referred evaluation (patients 1-6) tachycardia (patient 7) occurred after biatrial valvular surgery. During electrophysiologic study, slow...
This study aimed to investigate the risk factors for aggravation of cervical alignment after posterior foraminotomy (PCF) and identify their relationships with kyphotic changes in curvature.Ninety-eight patients who underwent PCF unilateral radiculopathy received follow-up more than 2 years were retrospectively reviewed. Segmental Cobb angle (SA), (CA), Pfirrmann grade, foraminal stenosis, clinical outcomes including neck pain, arm Neck Disability Index scores assessed. Radiological compared...
1,3-Propanediol (PDO) is a value-added chemical used widely in cosmetics, foods, lubricants, adhesives, and pharmaceuticals. Klebsiella oxytoca facultative anaerobe that can produce 1,3-PDO through the fermentation pathway of glycerol. Recently, (bio)electrochemically produced formate from CO2 has been highlighted as co-substrate environmentally friendly biological reducing agent for bioconversion. In this study, glycerol K. with various concentrations was examined to enhance production....
Objectives The purpose of this study was to find risk factors that are associated with complications cerebral infarction in patients atrial fibrillation (AF) and discover useful association rules among these factors. Methods respect were selected using logistic regression analysis the Wald's forward selection approach. identify obtained by rule mining (ARM) Results We observed 4 independent factors, namely, age, hypertension, initial electrocardiographic rhythm, echocardiographic left...
In this study, we propose an optimal method for monitoring the key electrophysiological sign, Lateral Spread Response (LSR), during microvascular decompression (MVD) surgery hemifacial spasm (HFS). Current methods and interpretations of LSR remain unclear, leading to potential misinterpretations undesirable outcomes." We prospectively collected data from patients undergoing MVD HFS, including basic demographics, clinical characteristics, surgical outcomes. Stimulation intensity was escalated...
Abstract Background An automated tagging module (VISITAG™; Biosense Webster, Irvine, CA) allows objective demonstration of energy delivery. However, the effect VISITAG™ on clinical outcomes remains unclear. This study evaluated (1) outcome after AF ablation using and (2) prevalence gaps in line. Methods retrospective analysis included 157 consecutive patients (mean age, 56.7 years; 73.2% men) with paroxysmal atrial fibrillation who underwent successful PVI between 2013 2016. Outcomes index...

Abstract Background The clinical implications of pericardial effusion (PE) after catheter ablation for atrial fibrillation (AF) are not well understood. We evaluated the association between newly developed PE pulmonary vein isolation (PVI) paroxysmal AF and arrhythmic recurrence. Methods From a prospective registry, 184 patients (mean age 59 ± 10 years, 65% male) who underwent first‐time PV using smart touch surround flow (Biosense Webster, Diamond Bar, CA) were analyzed.
