Filter by:Acute kidney injury is major complication after open heart surgery. The cause of acute kidney injury following open heart surgery is related to activation of sympathetic nervous system, decrease of renal blood flow, ischemia-reperfusion injury and systemic inflammatory response. Infective endocarditis patients undergoing open heart surgery have systemic inflammatory response associated with infective endocarditis. And the inflammatory response can be aggravated by cardiopulmonary bypass. The incidence of acute kidney injury following open heart surgery due to infective endocarditis was 50% in a previous report. And this acute kidney injury was related to the poor outcome and high mortality. Thus, the preventive method to protect kidney function will be needed in the patients with infective endocarditis undergoing open heart surgery. Dexmedetomidine is a selective α2-agonist and has sedative, analgesic, and CNS depressive effect. And several experimental study demonstrated the renal protective effect. Intraoperative dexmedetomidine administration can reduce the amount of anesthetics needed and suppress the sympathetic response resulted by surgical stimulation. And dexmedetomidine was reported to reduce the level of serum cortisol, epinephrine and norepinephrine during the operation. Thus, these effects of dexmedetomidine can be expected to reduce the incidence of acute kidney injury. Therefore, the investigators hypothesized that dexmedetomidine has renal protective effect and this effect might be related to the suppression of inflammatory response. Thus, the investigators will evaluate the incidence of acute kidney injury and the incidence of major adverse kidney events (MAKE) after open heart surgery due to infective endocarditis and the level of inflammatory mediators. The primary end point of this study is the incidence of acute kidney injury after open heart surgery due to infective endocarditis. And secondary end point is the incidence of MAKE, the level of cystatin C which is related to the renal function, the level of inflammatory mediator and the postoperative morbidities.
As recommended in the Guidelines on the prevention, diagnosis, and treatment of infective endocarditis (IE) patients with IE should be evaluated and managed by a multispecialty team including an cardiologist, infectious disease specialist, and cardiac surgeon. Our registry is a prospective, national registry of patients with IE. From January 2013 data from endocarditis board were prospectively recorded using standard definitions during the hospitalization. Patient demographics, clinical, laboratory, and imaging data at the time of IE diagnosis, as well as treatment outcomes were entered into the ER-UHC database.
The aim of this single-center randomized controlled trial is to assess clinical usefulness of positron emission tomography combined with computed tomography (PET CT) in the diagnostic process of suspected cardiovascular implantable electronic device (CIED) infection (lead dependent infective endocarditis, generator pocket infection, fever of unknown origin).
Background: Prognosis of infective endocarditis is poor and has remained steady over the last four decades. Several nonrandomized studies suggest that early surgery could improve prognosis. Methods: The early surgery in infective endocarditis study (ENDOVAL 1) is a multicenter, prospective, randomized study designed to compare the state-of-the-art therapeutic strategy (that advised by the international societies in their guidelines) with the early surgery strategy in high-risk patients with infective endocarditis. Patients with infective endocarditis without indication for surgery will be included if they meet at least one of the following: 1) early-onset prosthetic endocarditis; 2) Staphylococcus aureus endocarditis; 3) periannular complications; 4) new-onset conduction abnormalities; 5) vegetations longer than 10 mm in diameter; 6) new-onset severe valvular disfunction. A total of 216 patients will be randomized to either of the two strategies. Stratification will be done within 3 days of admission. In the early surgery arm, the procedure will be performed within 48 hours of randomization. The only event to be considered will be death within 30 days. The study will be extended to 1 year. In the follow-up substudy, death and a new episode of endocarditis will be regarded as events. Conclusion: The early surgery in infective endocarditis study (ENDOVAL 1), the first randomized in endocarditis, will provide crucial information regarding the putative benefit of early surgery over the state-of-the-art therapeutic approach in high-risk patients with infective endocarditis.
