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...

Operative mortality in congenital heart disease remains high. Implementing best medical practices and fostering healthy staff relationships are crucial for improving patient outcomes in pediatric cardiac surgery.

Area of Science:

  • Pediatric Cardiology
  • Surgical Outcomes Research
  • Healthcare Quality Improvement

Background:

  • Congenital heart disease (CHD) operative mortality rates have stagnated at 2.8% over the past decade.
  • A single pediatric heart center achieved a 365-day period of 0% operative mortality, prompting an investigation into contributing institutional factors.

Purpose of the Study:

  • To qualitatively identify institutional factors influencing operative mortality in CHD.
  • To compare these factors with perceived reasons for operative mortality.

Main Methods:

  • A convergent mixed-methods design integrating quantitative and qualitative data.
  • Retrospective review of 43 operative mortality records and semi-structured interviews with staff.
  • Analysis included descriptive statistics, reflexive thematic analysis, and a joint display for comparison.

A Modified Murine Heterotopic Heart Transplant Protocol Matching Contemporary Standards of Aseptic Technique, Anesthesia, and Analgesia

Published on: September 28, 2022

Main Results:

  • Key reasons for operative mortality included technical failure (22%), intractable disease (22%), communication issues (21%), management strategy (18%), and decision-making (16%).
  • Three emergent themes were: Implementing Best Medical Practices, Fostering Healthy Interpersonal Relationships, and Building a Responsive Organizational Structure.
  • Theme 1 aligned with technical failure, intractable disease, management strategy, and decision-making; Theme 2 aligned with communication; Theme 3 had limited association.

Conclusions:

  • Implementing best medical practices is essential for reducing operative mortality in CHD.
  • Fostering healthy interpersonal relationships among staff is a significant factor for improving outcomes.
  • Further research into responsive organizational structures may offer indirect benefits.
