The development of a remotely expandable anastomosis device for use in paediatric cardiothoracic surgery
… In all cases, these children will require review surgery, often several times to replace the implanted conduit as the child grows. Critically every review procedure carries with it an increased mortality risk.;This project represents the first stage in the development of a conduit/ anastomosis …

Sex Differences in Cardiac Electrophysiology
… that females have higher mortality following cardiothoracic surgery and the reason for this is unknown. During cardiothoracic surgery the heart is arrested and maintained by a fluid, cardioplegia solution. Cardioplegia solutions contain components that are known to modulate conduction. We …

The prevention and diagnosis of central venous catheter-related infection
… recovered from the skin and CVC components of 3 cardiothoracic surgery patients were characterised by pulsed-field gel electrophoresis (PFGE). The genetic heterogeneity of CoNS isolated from the skin was demonstrated and specific genotypes implicated in catheter colonisation. In addition, …

Postoperative glucose control : decreasing incidence of cardiothoracic surgical site infections in diabetic patients
… between diabetes and surgical site infection for cardiothoracic surgeries. The importance of postoperative glucose control on reducing the incidence of cardiothoracic surgical site infections amongst diabetic patients is reviewed. The research question: Amongst diabetic patients undergoing …

User Interfaces for Patient-Centered Communication of Health Status and Care Progress
… for patients at NYP. The portal, evaluated by cardiothoracic surgery patients, is the first of its kind to allow patients to capture and monitor live data related to their care. Patient use of the portal influenced the subsequent design of tools to support users in making sense of online …

Signal processing approaches to analyzing patient cardiovascular state
… into a patient's cardiovascular state during surgery and causes of fluctuations in hemodynamics. Recent work suggests that time spent outside a certain blood pressure range corresponds to an increased risk of adverse outcomes after surgery. An analysis of blood pressures recorded during …

Pulmonary endarterectomy for chronic thromboembolic pulmonary hypertension in Cape Town, South Africa
… and objectives: We interrogated the Adult Cardiothoracic Surgery database at the University of Cape Town (UCT) between December 2005 and April 2021 for patients undergoing PEA at Groote Schuur Hospital and Netcare UCT Private Academic Hospital. The primary outcome was the difference in …

Long term outcome and the validity of EuroSCORE II in native-valve surgery for active endocarditis in a South African cohort
… for predicting the early mortality after cardiac surgery. HYPOTHESIS: Infective endocarditis has a high risk for mortality due to certain risk factors and the currently available EuroSCORE II model may not predict early mortality accurately and may not be suitable for our patient population. …

The impact of HIV on 30-day survival amongst patients undergoing cardiac surgery at Groote Schuur Hospital in the ART era
… and mortality in patients undergoing cardiac surgery in sub-Saharan Africa (SSA) in the AntiRetroviral Therapy (ART) era is not known. Pre ART era data from South Africa suggested that patients with a CD4 count less than 400 should be selected with caution. European and North American …

Ultrasonography Evaluation of Patency of Implanted Infra-Renal Vascular Grafts in the Rat Model.
Introduction: Intensive research over the last six decades has resulted in minimal improvement in vascular graft development. Small animal models are the first line of species exposed to vascular graft implantation and invasive monitoring of experimental graft patency may contribute to pain, …

Mid-Term Outcome Of A Decade Of Delayed Total Cavopulmonary Connection Completion Strategy At Red Cross War Memorial Children's Hospital.
Background: Total cavo-pulmonary connection (TCPC) is currently the definitive palliative operation for single ventricle congenital anomalies. It is the last stage in the single ventricle pathway and can be completed following a bidirectional Glenn shunt (BGS), if a set of strict criteria are met. …

Importance of renal function in cardiac surgery
… (AKI) is a common and serious complication after cardiothoracic surgery and is associated with increased short- and long-term mortality risk. Despite extensive studies in the field, a comprehensive understanding of this syndrome has remained elusive, partly due to divergent definitions of AKI and …

Phosphorylation of TASK-1 and its role in atrial arrhythmias
… Acute-onset AF is frequently associated with cardiothoracic surgery, and its initiation is thought to involve proinflammatory signaling. Activated neutrophils are known to be arrhythmogenic, and one of the inflammatory mediators released from neutrophils that contributes to arrhythmogenicity …

Paravalvular sealing pf percutaneous heart valves
Paravalvular regurgitation (PVR), which frequently occurs after transcatheter aortic valve replacements (TAVR) can lead to adverse clinical consequences and has been shown to correlate to an increased late mortality and morbidity. Quantification, graduation and testing for PVR has proven …

A theoretical study of left ventricular and heart muscle dynamics
The characteristics of the left ventricle of the human heart considered as a pump have been extensively analysed. Using a new approach relying heavily on the Tensor Calculus, a theoretical model describing the mechanical and dynamical operation of the left ventricle has been developed. This has …
