Filter by:The aim of this study is to evaluate the analgesic efficacy and safety of wound infiltration with liposomal bupivacaine (LB) in patients undergoing cardiac surgery with sternotomy and cardiopulmonary bypass (CPB) and compare it with bupivacaine hydrochloride infiltration
The aim of this study is to improve the definition of the two main types of secondary tricuspid regurgitation.
randomized study which include comparison rigid ring and band devices in treatment tricuspid regurgitation.
The current management of tricuspid regurgitation (TR) is either conservative (by medication) or by surgery, usually in concomitant with other valves repair or replacement. TR can worsen or appear late after successful mitral valve surgery which portends a poor prognosis. However, standard surgical approaches requiring cardiopulmonary bypass and especially second surgery have an excessive risks. Thus many patients are denied surgery because of unfavorable risk-benefit balance. Therefore there is a need for novel devices enabling interventional cardiologists and cardiothoracic surgeons to perform tricuspid annuloplasty by transcatheter methods. Cardioband replicates established surgical techniques (e.g., annuloplasty) using transfemoral approach, without sutures and with adjusted on the beating heart. Similar to the approved indication for mitral annuloplasty. The Cardioband System is expected to allow for treatment of patients that would otherwise not undergo Tricuspid valve repair due to the invasiveness of current techniques.
Serum-creatinine level (s-Cr) is an important factor for predicting perioperative patient's outcome regarding acute kidney injury. Although cardiopulmonary bypass (CPB), an essential procedure for cardiac surgery, dilutes patient's blood components, possible impact of applying acute normovolemic hemodilution (ANH) and CPB on s-Cr has not been well investigated. In patients undergoing cardiac surgery employing moderate hypothermic CPB (age 20-71 years, n=32), ANH will be randomly applied to 15 patients (Group-ANH) but not in 17 patients (Group-C) before initiating CPB. For ANH procedure consisting of 5 ml/kg of blood salvage and administering 5 ml/kg of balanced hydroxyethyl starch (HES) 130/0.4 for 15 min will be started at 30 min after anesthesia induction and before CPB application for surgery. In both groups, moderate hypothermic CPB will be initiated by using 1600-1800 ml of bloodless priming solution. The changes of hematocrit (Hct), Na+, K+, HCO3-, Ca2+, osmolarity, s-Cr will be determined before ANH (T1), after the first ANH of 2.5 ml/kg (T2), and after the second ANH of 2.5 ml/kg (T3), 30 sec and 60 sec after the initiation of CPB (T4, T5), immediately and 1 hour after the weaning from CPB (T6, T7) and at the end of surgery (T8). S-Cr will be determined by using a point-of-care test device (StatSensor™ Creatinine, Nova Biomedical, USA).
The purpose of the study is to assess the safety and device performance of the Edwards Tricuspid Transcatheter Repair System in patients with clinically significant, symptomatic, tricuspid regurgitation who are at high surgical risk for standard tricuspid repair/replacement.
The investigators research the early improvement of fluid retention and mid-term prognosis through the administration of tolvaptan for the patient with tricuspid regurgitation and right heart failure after left heart valves replacement.
Impact of acute normovolemic hemodilution (ANH) using hydroxyethyl starch before initiating cardiopulmonary bypass (CPB) on whole blood viscoelastic profile after CPB has not been well established. Patients undergoing cardiac surgery employing moderate hypothermic CPB (n=40) are randomly allocated into one of two groups: in Group-ANH(n=20), ANH is applied by using a balanced hydroxyethyl starch (HES 130/0.6); and in Group-C, ANH is not applied. After weaning from CPB, intergroup differences of INTEM, EXTEM, FIBTEM and APTEM profiles are analyzed. As a primary outcome, inter-group difference between maxiaml clot firmness of EXTEM will be determined at 10 min after ANH in Group-ANH and that at control.
The study is a multi-center, prospective, early feasibility study to measure individual patient clinical outcomes and effectiveness, evaluate the safety and function, provide guidance for future clinical study designs and development efforts of the Edwards FORMA Tricuspid Transcatheter Repair System.
The TriCinch System™ is intended for percutaneous treatment of tricuspid regurgitation. It is a percutaneous catheter-based device designed for tricuspid valve repair in order to decrease effective cross-sectional area and relieve symptoms in patients with tricuspid valve regurgitation.
