Aortic valve replacement using the Freedom SOLO stentless bioprosthesis: clinical and haemodynamic performance in 625 patients at medium-term follow-up.

Objectives: Our goal was to analyse the haemodynamic and clinical results after implantation of the Freedom SOLO stentless aortic valve replacement by assessing the immediate postoperative results regarding mortality, discharge echocardiographic gradients and reoperation rates and by evaluating these results in the medium term.

Methods: This study was designed as a single-centre retrospective observational trial. Clinical and echocardiographic data were collected retrospectively from 625 patients undergoing an aortic valve replacement using the Freedom Solo stentless valve (LivaNova, London, UK) at the Sint-Jan Hospital, Bruges, between May 2009 and May 2017.

Diagnosis and treatment of Aspergillus flavus sternal wound infections after cardiac surgery.

We report the clinical data for 9 patients affected during an outbreak of Aspergillus flavus sternal wound infections after cardiac surgery. In 7 patients, the infection had a locally invasive character, with 3 of these patients having multiple relapses; 2 patients had fulminant mediastinitis and died. Most patients received combined surgical and medical treatment.

Pulsatile compared with nonpulsatile perfusion using a centrifugal pump for cardiopulmonary bypass during coronary artery bypass grafting. Effects on systemic haemodynamics, oxygenation, and inflammatory response parameters.

The present study investigated the influence of pulsatile or nonpulsatile flow delivery with a centrifugal pump for cardiopulmonary bypass (CPB) during coronary artery bypass grafting (CABG) in two randomized groups of 19 patients each. All patients received a standard anaesthetic and surgical protocol. Pulsatile perfusion during CPB was created by accelerating the baseline pump speed of the Sarns centrifugal pump at a rate of 50 cycles per minute.

Cardiac arrest due to aberrant left coronary artery originating from the right sinus of Valsalva in a young girl.

We report a 14-year-old girl who sustained a syncope followed by cardiac arrest. She was kept alive for three days by full cardiocirculatory support using left and right ventricular assist devices, but subsequently died in multiple organ failure. Autopsy revealed an anomalous origin of the left coronary artery (LCA) from the right sinus of Valsalva (RSV) and a major left anterior wall infarction.
