Objective: To compare the value of two 3D imaging reconstruction methods for left atria and pulmonary vein on guiding the catheter ablation for atrial fibrillation (AF). Methods: From January 2014 to January 2017, a total of 100 drug refractory paroxysmal AF patients were divided into left atria direct angiography group (n=50), and indirect angiography group (n=50). 3D CARTO system was applied for mapping and guiding the ablation procedure. Patients assigned to direct angiography group were treated as follows: intraoperative puncture of atrial septum, inject contrast agent directly into the left atrium, conduct left atrial and pulmonary venous rotation angiography, reconstruct three-dimensional image, integrate the image into real-time X-ray system to facilitate circumferential pulmonary vein isolation...

Monoamines, acting as hormones and neurotransmitters, play a critical role in multiple physiological processes ranging from cognitive function and mood to sympathetic nervous system activity, fight-or-flight response, or glucose homeostasis. In addition to brain and blood, monoamines are abundant in several tissues, and dysfunction in their synthesis or signaling is associated with various pathological conditions. It was our goal to develop a method to detect these compounds in peripheral murine tissues. In this study, we employed a high performance liquid chromatography method using electrochemical detection that allows not only detecting the catecholamines but a detailed analysis of nine monoamines and metabolites in murine tissues...

Background The reported incidence rate of bile duct injury (BDI) during laparoscopic cholecystectomy (LC) is 0.3%. However, routine use of intraoperative cholangiography (IOC) is a controversial, due to the additional cost and radiation exposure. The aim of this study was to assess the application of fluorescence cholangiography (FC) in comparison to IOC and to LC without any intraoperative imaging. Materials and Methods This prospective study included 230 patients undergoing LC in our institution. The subjects were divided into two groups...

Background Large bone defects and losses play a crucial role in both tumour surgery and in complex primary and revision total knee replacement. The established options of cemented or uncemented long intramedullary stems are limited by large bone defects and are at risk from relatively high exposure to aseptic loosening. There is no general valid agreement on implant fixation of the distal femur. A further option is the cementless fixation method with compressive osseointegration, based on the so-called Wolff law of bone remodelling...

Correct detection of membrane currents under whole-cell patch-clamp conditions is limited by the transfer function of a recording system. The low-pass output filter of a recording amplifier alters the time course of membrane current and causes errors in relevant descriptors. To solve these problems, we developed a practical procedure for reconstruction of the time course of membrane currents based on deconvolution of recorded currents in frequency domain. The procedure was tested on membrane capacitance estimates from current responses to step voltage pulses...

BACKGROUND: The first-line therapy for atrioventricular nodal reentry tachycardia (AVNRT) is catheter-based slow pathway modulation. If AVNRT is not inducible during an electrophysiological study, an empirical slow pathway modulation (ESPM) may be considered in patients with dual atrioventricular nodal physiology and/or a typical electrocardiogram (ECG). METHODS: We screened 149 symptomatic patients who underwent ESPM in our department between 1993 and 2013. All patients fulfilled the following criteria: (1) either dual atrioventricular nodal (AVN) physiology with up to 2 AVN echo beats or characteristic ECG documentation or both, (2) noninducibility of AVNRT by programmed stimulation, and (3) completion of a telephone questionnaire for long-term follow-up...

BACKGROUND: Although transvenous right ventricular (RV) endocardial lead placement is routine practice in clinical pacing, RV inaccessibility in certain clinical situations mandates the search for other sites. HYPOTHESIS: This study is aimed to verify whether left ventricular lead through coronary sinus is safe and efficient. METHODS: Based on a retrospective analysis of a single-center series of 4 patients with inaccessibility for RV pacing, we report on the feasibility and reliability of coronary sinus (CS) pacing via left ventricular (LV) lead, which usually is used in cardiac resynchronization therapy...

Solid organ transplantation is a significant development in the treatment of chronic kidney, liver, heart and lung diseases. This therapeutic approach has increased patient survival and improved quality of life. New surgical techniques and immunosuppressive drugs have been developed to achieve better outcomes. However, the variety of neurological complications following solid organ transplantation is broad and carries prognostic significance. Patients may have involvement of the central or peripheral nervous system due to multiple causes that can vary depending on time of onset after the surgical procedure, the transplanted organ, and the intensity and type of immunosuppressive therapy...

There is growing competition for non-operative, procedural training in teaching hospitals, due to an increased number of individuals seeking to learn procedures from a finite number of appropriate teaching cases. Procedural training is required by students, post-graduate learners, and practicing providers who must maintain their skills. These learner groups are growing in size as the number of medical schools increase and advance practice providers expand their skills to include complex procedures. These various learner needs occur against a background of advancing therapeutic techniques that improve patient care, but also act to reduce the overall numbers of procedures available to learners...

The world of breast reconstruction over the last several years has seen a dramatic shift in focus to discussion and the application of placing tissue expanders and implants back into the prepectoral space. Although this technique failed during the early advent of breast reconstruction, newer technologies such as advances in fat grafting, improved acellular dermal matrices, better methods of assessing breast flap viability, and enhanced implants appear to have set the stage for the resurgence and positive early results seen with this technique...

Prepectoral breast reconstruction has emerged as an excellent technique for postmastectomy reconstruction, as it allows for full preservation of a patient's pectoralis major muscle and chest wall function. This reduces pain, eliminates animation deformity, and results in high patient satisfaction. Safely performed prepectoral breast reconstruction requires a careful patient selection process before committing to the procedure, taking into account comorbidities, radiation status, and oncologic criteria such as tumor location and breast cancer stage...
