Comparison of Procedural Sedation With Propofol and Dexmedetomidine During Transcatheter Aortic Valve Replacement Using the Transfemoral Approach.

Objectives: Although procedural sedation is an established method of anesthesia for transcatheter aortic valve replacement (TAVR), reliable evidence to guide the choice of a suitable sedative agent remains scarce. Accordingly, this trial aimed to compare the effect of procedural sedation with dexmedetomidine versus propofol on postoperative neurocognitive and related clinical outcomes in patients undergoing TAVR.

Design: Prospective, randomized, double-blind clinical trial.

Cerebral microemboli in mini-sternotomy compared to mini- thoracotomy for aortic valve replacement: a cross sectional cohort study.

Background: Recently adopted mini-thoracotomy approach for surgical aortic valve replacement has shown benefits such as reduced pain and shorter recovery, compared to more conventional mini-sternotomy access. However, whether limited exposure of the heart and ascending aorta resulting from an incision in the second intercostal space may lead to increased intraoperative cerebral embolization and more prominent postoperative neurologic decline, remains inconclusive. The aim of our study was to assess potential neurological complications after two different minimal invasive surgical techniques for aortic valve replacement by measuring cerebral microembolic signal during surgery and by follow-up cognitive evaluation.

Hybrid coronary revascularization versus percutaneous strategies in left main stenosis: a propensity match study.

Aims: Hybrid revascularization (HCR) has been recently proposed as an alternative strategy in multivessel coronary disease, particularly in patients with high SYNTAX scores and risk scores. The objective of this study is to evaluate the outcomes of HCR versus percutaneous coronary intervention (PCI) drug-eluting stenting in left main treatment.

Methods: A series of 198 consecutive patients with left main stenosis have been treated.

Stentless sutureless and transcatheter valves: a comparison of the hemodynamic performance of different prostheses concept.

Background: Stentless aortic valves have been developed to overcome obstructive limitations associated with stented bioprostheses. A new concept of surgical sutureless (SU) bioprosthesis has been developed in the last decade. In this multi-institutional study we sought to compare hemodynamics of different bioprosthesis concept as transcatheter (TAVR), Livanova Perceval S sutureless valve and Freedom Solo Stentless (FS) valve in patients undergoing aortic valve replacement (sAVR).

Early hemodynamics and clinical outcomes of isolated aortic valve replacement with stentless or transcatheter valve in intermediate-risk patients.

Objective: Stentless aortic valves have been developed to overcome obstructive limitations associated with stented bioprostheses. The aim of the current multi-institutional study was to compare hemodynamics of transcatheter (TAVR) and the Freedom SOLO Stentless (FS) valve in an intermediate risk population undergoing surgical aortic valve replacement.

Methods: From 2010 to 2014, 420 consecutive patients underwent isolated surgical aortic valve replacement with FS and 375 patients underwent TAVR.

Enhanced Recovery After Kidney Transplantation Surgery.

Background: Enhanced recovery after surgery (ERAS) protocols have gained widespread recognition in general surgery, decreasing the length of hospital stay while maintaining equivalent or lower morbidity and increased patient satisfaction. The feasibility of the ERAS protocol has not been studied in kidney transplantation. In this single-center retrospective case series, we describe the outcomes of 45 consecutive deceased-donor kidney transplant recipients subjected to a modified ERAS protocol, and we discuss the potential for future developments.

Operability assessment in CTEPH: Lessons from the CHEST-1 study.

Pulmonary endarterectomy is the gold standard treatment for chronic thromboembolic pulmonary hypertension and is potentially curative, although some patients are unsuitable for pulmonary endarterectomy and require alternative management. Lack of standardized assessment of pulmonary endarterectomy eligibility risks suboptimal treatment in some patients. We discuss the implications for future clinical trials and practice of a unique operability assessment in patients who have chronic thromboembolic pulmonary hypertension and were initially screened for inclusion in the CHEST-1 (Chronic Thromboembolic Pulmonary Hypertension Soluble Guanylate Cyclase Stimulator Trial-1) study.

Transcatheter aortic valve implantation in a cancer patient denied for surgical aortic valve replacement-a case report.

Background: Aortic stenosis is a progressive disease. Symptomatic aortic stenosis has a poor prognosis, which is frequently worse than that of a malignant disease. Cancer patients with severe aortic stenosis may be denied for optimal oncologic treatment because of high operative risk and for aortic valve replacement because of the significant comorbidity itself.

Use of dressing with human fibrin and thrombin during resection of a right atrial angiosarcoma.

Primary malignant cardiac tumors are rare and are usually detected at an advanced stage of disease. Their location and infiltration often hinder surgical resection. Tissue sarcomas, especially angiosarcomas, are composed of irregular and delicate vascular tissue.

Thrombophilia and pulmonary endarterectomy.

Unlabelled: In the present study, we compared groups of patients with and without thrombophilia, who underwent pulmonary endarterectomy (PEA), definitive treatment for chronic pulmonary hypertension resulting from thromboembolic disease.

Methods And Patients: Between September 2004 and June 2007, we operated 54 patients with CTEPH. We divided our patients into three groups.

Diagnostics of "non-acute" vascular prosthesis infection using 18F-FDG PET/CT: our experience with 96 prostheses.

Introduction: Vascular prosthesis infection (VPI) is a life-threatening complication that occurs in 0.5-5% of prostheses. Low-grade infections in non-acute patients are a diagnostic challenge requiring a new method with good diagnostic accuracy.

Particle image velocimetry measurement in the model of vascular anastomosis.

Neointimal hyperplasia is the most common complication of all forms of arterial reconstructions. This response of the vascular wall to injury is influenced by many factors, especially, but not limited to, by the hemodynamic profile in the area of vascular anastomosis and in its close proximity. To eliminate this negative influence of hemodynamics on progression of neointimal hyperplasia, we tried to develop anastomosis with optimal hemodynamic parameters.

Implementation of a new programme for the surgical treatment of CTEPH in the Czech Republic--Pulmonary endarterectomy.

Background: Chronic thromboembolic pulmonary hypertension (CTEPH) in indicated cases can be successfully cured by endartectomy of pulmonary arteries (PEA). Symptomatic nontreated CTEPH has a very poor prognosis; the five-year survival rate in patients with a medium pressure of over 50 mmHg in the main pulmonary artery is as low as 10 %. This kind of operation was previously not available in the Czech Republic.
