Complications In Cardiac Surgery, Christine Williamitis

Theses and Dissertations--Nursing

Quality of care and outcomes from cardiac surgery have always been of primary importance to providers and the entire health care team when caring for cardiac surgical patients. Providers in cardiac surgery have had a long history of tracking procedural morbidity and mortality rates in programs nationally and internationally. Morbidity and mortality rates vary widely among hospitals. In most studies in which procedural outcomes from cardiac surgery are evaluated, the focus has been on operative morbidity and mortality and the probability of death after a cardiac surgical procedure. Less attention has been paid to predictors of perioperative complications, and sample …

Pulling Heart Strings: Quality Improvement Algorithm For Temporary Epicardial Pacing Wire Removal Post Cardiac Surgery, Jessica Norman

Doctors of Nursing Practice (DNP) Final Projects, 2020-current

The placement of temporary epicardial pacing wires (TEPW) is considered standard practice post cardiac surgery and is dependent on the patient’s cardiac function intra-operatively and their electrophysiologic profile after weaning from cardiopulmonary bypass (Reade, 2007; Elmistekawy et al, 2016). Complications associated with TEPW removal include myocardial damage, infection, perforation, tamponade, disruption of anastomoses, ventricular arrythmias, and death (Bojar, 2009; Carroll et al, 1998;Timothy & Rodeman, 2004). Currently there is no standard practice on the removal of TEPW and there is wide variation in removal practices involving patients who are routinely on medications such as dual antiplatelet therapies and systemic anticoagulation. …

Augmented Image-Guidance For Transcatheter Aortic Valve Implantation, Pencilla Lang

Electronic Thesis and Dissertation Repository

The introduction of transcatheter aortic valve implantation (TAVI), an innovative stent-based technique for delivery of a bioprosthetic valve, has resulted in a paradigm shift in treatment options for elderly patients with aortic stenosis. While there have been major advancements in valve design and access routes, TAVI still relies largely on single-plane fluoroscopy for intraoperative navigation and guidance, which provides only gross imaging of anatomical structures. Inadequate imaging leading to suboptimal valve positioning contributes to many of the early complications experienced by TAVI patients, including valve embolism, coronary ostia obstruction, paravalvular leak, heart block, and secondary nephrotoxicity from contrast use.
