Clinical outcome and hemodynamic behavior of the Labcor Dokimos Plus aortic valve

Background The Labcor Dokimos Plus (LDP) is a stented externally mounted pericardial aortic bioprosthesis, which was recently introduced in Europe. Aims of the study are evaluation of operative and postoperative results as well as hemodynamic performance. Methods One hundred consecutive patients with a mean age of 65.9 ± 10.7 years (range 35–87) and a mean EuroSCORE II of 3.1 ± 3.9 ...

Surgery for prosthetic valve endocarditis: associations between morbidity, mortality and costs†

OBJECTIVES Surgery for prosthetic valve endocarditis (PVE) is associated with significant morbidity and mortality as well as with increased resource utilization and costs. For risk and cost reduction, an understanding of contributing factors and interrelations is essential.

Stentless aortic valve replacement in the young patient: long-term results

Background Stentless aortic valve replacement (SAVR) became a common surgical procedure to treat aortic valve disease, as it offers larger orifice area and improved hemodynamics. The aim of our single-centre retrospective study was to assess long term results of first generation stentless aortic valves in young patients, where mechanical prostheses are considered first line ...

Noninvasive monitoring of cardiac function in a chronic ischemic heart failure model in the rat: Assessment with tissue Doppler and non-Doppler 2D strain echocardiography

Objectives Feasibility of noninvasive monitoring of cardiac function after surgically induced ischemic cardiomyopathy with tissue Doppler and non-Doppler 2D strain echocardiography in rats. Background The optimal method for quantitative assessment of global and regional ventricular function in rats with chronic heart failure for research purposes remains unclear. Methods 20 rats ...

Concomitant ablation of atrial fibrillation in octogenarians: an observational study

Background Cardiac surgery is increasingly required in octogenarians. These patients frequently present atrial fibrillation (AF), a significant factor for stroke and premature death. During the last decade, AF ablation has become an effective procedure in cardiac surgery. Because the results of concomitant AF ablation in octogenarians undergoing cardiac surgery are still not clear, ...

Temporary left ventricular assist and levosimendan for coronary artery spasm

Coronary vasospasm is a life threatening complication in the early postoperative period after coronary artery bypass grafting. We report a 45-year-old patient with normal preoperative ventricular function who could not be stabilized using established treatments such as: systemic application of glyceryl trinitrate, diltiazem and milrinone, intraaortic balloon pumping and ...

Biventricular assist device in extreme anorexia nervosa

Low body mass index is an independent risk factor in cardiac surgery. Cardiac function may be severely impaired in the case of extreme malnutrition and require cardiac assistance if cardiac surgery is necessary. We report a case of the successful use of a biventricular assist device in a patient with an extreme low body mass index (6.7) due to anorexia nervosa for recovery after ...

Atypical vessels as an early sign of intracardiac myxoma?

We report on a woman with previously unknown left atrial myxoma, who underwent percutaneous coronary intervention. 45 months after the initial coronary angiography, echocardiography demonstrated a large atrial myxoma, which was not seen echocardiographically before. The retrospective analysis of the pre-intervention coronary angiography revealed atypical vessels in the atrial ...

Correction: Bispectral index versus COMFORT score to determine the level of sedation in paediatric intensive care unit patients: a prospective study

Bispectral index versus COMFORT score to determine the level of sedation in paediatric intensive care unit patients: a prospective study

Introduction Most clinicians give sedatives and analgesics according to their professional experience and the patient's estimated need for sedation. However, this approach is prone to error. Inadequate monitoring of sedation and analgesia may contribute to adverse outcomes and complications. With this in mind, data obtained continuously using nonstimulating methods such as ...

Levosimendan may improve survival in patients requiring mechanical assist devices for post-cardiotomy heart failure

Introduction Most case series suggest that less than half of the patients receiving a mechanical cardiac assist device as a bridge to recovery due to severe post-cardiotomy heart failure survive to hospital discharge. Levosimendan is the only inotropic substance known to improve medium term survival in patients suffering from severe heart failure. Methods This retrospective ...
