Insights

Epi-aortic scanning effectively identifies aortic atheroma, a primary cause of stroke after cardiac surgery. This cost-effective method can reduce perioperative stroke incidence, making it a valuable addition to routine practice.

Area of Science:

  • Cardiovascular Surgery
  • Neurology
  • Medical Technology

Background:

  • Stroke is a significant complication of cardiac surgery, with an annual rate of 2.6% in the UK.
  • Aortic atheroma is the leading cause of stroke following coronary artery bypass graft procedures.
  • Current stroke prevention strategies in the UK may not be resource-efficient.

Purpose of the Study:

  • To evaluate the role of carotid artery intervention and peri-operative epi-aortic scanning in preventing stroke during cardiac surgery.
  • To assess the cost-effectiveness of current stroke prevention methods versus epi-aortic scanning.
  • To advocate for the adoption of epi-aortic scanning in routine cardiac surgical practice.

Main Methods:

  • Review of stroke risk factors in cardiac surgery.
  • Analysis of stroke incidence and prevention costs within the UK National Health Service.
  • Evaluation of the effectiveness of epi-aortic scanning in identifying aortic atheroma and reducing perioperative brain damage.

Main Results:

  • Aortic atheroma is the foremost cause of post-coronary artery bypass graft strokes.
  • Epi-aortic scanning is effective in identifying aortic atheroma and is a low-cost intervention.
  • Studies confirm that epi-aortic scanning reduces perioperative brain damage during heart surgery.

Conclusions:

  • Epi-aortic scanning is a valuable tool for identifying aortic atheroma and reducing stroke risk in cardiac surgery.
  • The cost-effectiveness of epi-aortic scanning warrants its adoption into routine cardiac surgical practice.
  • Further confirmation of its cost-effectiveness in brain protection during surgery is recommended.

Cardiomyopathy VII: Pre and Post Operative Nursing Management

Patients with hypertrophic cardiomyopathy (HCM) and left ventricular outflow tract (LVOT) obstruction who remain symptomatic despite optimal medical therapy may undergo a septal myectomy (Morrow procedure). This procedure involves excising a portion of the hypertrophied septum below the aortic valve using a heart-lung machine to improve blood flow through the LVOT. Effective preoperative and postoperative nursing management ensures successful patient outcomes, minimizes complications, and...

Cardiac Catheterization I: Pre-Procedure Overview

Cardiac catheterization is an invasive diagnostic technique used to identify and evaluate structural and functional diseases of the heart and major blood vessels. This technique diagnoses congenital heart disease, coronary artery disease, valvular heart disease, and coronary spasms and assesses ventricular function. It helps guide treatment decisions, including the need for revascularization procedures like percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) and...

Venous Thrombosis III: Interprofessional Care

Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...

Nursing responsibilities before cardiac catheterization include:Assess for allergies and establish baseline health status.Before cardiac catheterization, assess the patient for allergies to contrast dye. Perform a comprehensive baseline assessment, including vital signs, heart and breath sounds, and a neurovascular assessment of the extremities, noting distal pulses, skin color, and temperature. Instruct the patient to fast for 8-12 hours before the procedure. Evaluate baseline laboratory...
