Filter by:This prospective study will be performed in the Cardiothoracic (Chesterman) Department at Sheffield Teaching Hospitals NHSFT, Northern General Hospital. Pre-operative patients undergoing surgical valvular intervention, breathing both spontaneously and mechanically will be included in the trial. All patients will already have a central venous catheter inserted as part of their ongoing care. Patients will be eligible for the study irrespective of diagnosis or neck size. Patient demographical data will be recorded by Sam Jenkins following written consent, the day before the trial. The goal of this study is to determine if ultrasound assessment of Jugular Venous Pressure (JVP) accurately predicts Central Venous Pressure (CVP). Secondary objectives aim to identify if using the angle of Louis to approximate the location of the right atrium produces inaccuracies when measuring JVP. Comparing results in patients breathing spontaneously or under positive pressure ventilation will identify if the form of ventilation impacts on JVP and CVP recording. Correlating results between physical JVP examination and ultrasound assessment of JVP to measure CVP will conclude if ultrasound is a more appropriate tool, in an era where the physical examination of the cardiovascular system is becoming less valuable.
To compare mechanic and thermic stability of pericardium fixated either with 0.6% glutaraldehyde for 10 minutes or with 0.6% glutaraldehyde for 20 minutes
The study evaluates the efficacy of local anesthestic application through the catheter in the surgical wound for the postoperative pain relief after minimally invasive aortic valve surgery. The patients will be enrolled in two different groups according to the protocol of the local anesthetic and saline administration: 1. group: continous infusion of the local anesthetic plus bolus on demand 2. group: continous infusion of saline plus bolus on demand For all patients metamizol every 12 hours plus bolous of piritramid on demand.
Many cardiologists are convinced that early surgery in asymptomatic aortic stenosis (AS) saves lives. However there is currently no direct evidence for this and most recommendations from the ESC/ EACTS or ACC/ AHA in this field are supported by Level-B or C evidence. Therefore, the investigators designed a randomized controlled trial to demonstrate whether early surgery improves mortality and morbidity of patients with asymptomatic severe AS and low operative risk.
The aim of the present study is to assess in a "real life" case list the outcome of three different surgical approaches for isolated aortic valve surgery in terms of surgery times, morbidity and mortality.
