Background: Preoperative anaemia is a risk factor for adverse postoperative outcomes after cardiac surgery. Iron deficiency is a frequent cause of low preoperative haemoglobin. An effective treatment for preoperative anaemia associated with iron deficiency has not been determined.

Background: Coronavirus disease (COVID-19)-associated coagulopathy is most often characterized by elevated D-dimer, interleukin-6, and plasma fibrinogen concentrations as well as hypercoagulability in thromboelastometry with increased clot firmness in the EXTEM, INTEM, and FIBTEM assays. Clinically, it manifests with a very high incidence of thrombosis, particularly in the pulmonary system, whereas bleeding complications are infrequent.
Case: Here, we describe two critically ill patients with COVID-19 admitted to our intensive care unit demonstrating different thromboelastometry and biomarker patterns.
Background: Warfarin is commonly initiated post-cardiac surgery to reduce the risk of intracardiac thrombus formation. Studies have found that sensitivity is increased after cardiac surgery and anticoagulation is subsequently difficult to manage. This study set out to identify clinical markers of increased warfarin sensitivity in patients after cardiac surgery, and build a model that can predict warfarin sensitivity, and improve safety in this setting.

Report results of valve-in-valve therapy (ViV-TAVI) in failed supra-annular stentless Freedom Solo (FS) bioprostheses, which are the highest risk for coronary occlusion.
Methods: Six patients with FS valves (mean age 78.
Background: Surgical risk scoring systems are poor at predicting outcome in patients undergoing transcatheter aortic valve implantation (TAVI). Frailty indices might more accurately predict outcome.
Aims: To examine multiple frailty indices as markers of performance to see whether they predict outcomes both in the shorter (30 days) and longer terms (5 years) in patients who have undergone TAVI.
Objectives: The transradial approach limits vascular complications in coronary interventions. The same may be true for transcatheter aortic valve implantation (TAVI). We present our experience using secondary transradial arterial access.

Traditionally, in most centers, this procedure is done under GA, but more recently procedures with MAC have been reported.

The possibility of implanting aortic valves without recourse to sternotomy or cardiopulmonary bypass has been embraced by cardiologists, surgeons and patients alike as a revolution in management. First performed in 2002 by Alain Cribier, the technique has exploded into common use during the last three years, such that over 20,000 implants have now been undertaken worldwide.

Large bore vascular access is required, and successful management of this arterial access is key to overall procedural success. We report outcomes and complications using the Prostar vascular closure device following BAV and TAVI.

Background: Transcatheter aortic valve implantation (TAVI) is a new treatment strategy for patients with symptomatic aortic stenosis who are high risk for traditional surgical aortic valve replacement. The incidence of conduction system abnormalities after the procedure is significant. We examine our experience with CoreValve TAVI focusing on electrocardiographic changes found pre-, peri-, and postintervention.
View Article and Find Full Text PDFPatients with idiopathic thrombocytopenic purpura have safely undergone cardiac surgical procedures; however, platelets were transfused in 20 of 24 reported instances, and no point-of-care testing of coagulation status was performed. Herein, we report the case of a patient with idiopathic thrombocytopenic purpura who required urgent coronary artery bypass grafting and intra-aortic balloon pump support. Rotational thromboelastometry was used as a point-of-care test of the patient's coagulation status.

Background: Without surgical correction, survival of patients with severe symptomatic aortic stenosis is poor. It is unknown whether patients undergoing transcatheter aortic valve implantation (TAVI) have a better prognosis than similar patients who are treated with medical management.

Objectives: We have developed an approach where percutaneous aortic valve (PAVI) procedures are done under remifentanil-based sedation administered by an anesthetist. We report here our initial experience.
Background: Percutaneous aortic valve implantation is proving to be an effective treatment for aortic stenosis in patients with significant comorbidity precluding surgical aortic valve replacement.
