Filter by: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 research is to determine whether repairing a tricuspid valve (TV) in patients with mild to moderate tricuspid regurgitation (TR), at the time of planned mitral valve surgery (MVS), would improve the heart health of those who receive it compared to those who do not. At this point, the medical community is split in their opinion on whether surgeons should routinely repair mild to moderate TR in patients who are undergoing planned mitral valve surgery, and this study will answer this question.
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 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.
Prospective registry for patients with severe isolated tricuspid regurgitation (TR) without significant left-sided valvular or myocardial diseases. Aim: To evaluate clinical course and prognostic factors of patients with severe isolated TR.
Preoperative right ventricular end-systolic area (RV-ESA) and hemoglobin level were suggested as independent prognosticator for predicting long-term prognosis in patients with isolated severe TR undergoing corrective surgery We attempted to explore whether early postoperative echocardiography provides additional prognostic information on top of preoperative clinical and echocardiographic variables.
The effect of cardiac pacing leads on tricuspid regurgitation is unclear. This study will determine whether using a smaller diameter leads and an alternate position in the ventricle, the proximal septum, will reduce tricuspid regurgitation than larger leads placed in the apex.
The purpose of this study is to compare cardiac output results obtained using the thermodilution push technique with the Pulmonary Arterial Catheter (PAC) to the predicted cardiac output results obtained from the non-invasive FloWave™ 1000 device.
