Insights

Pediatric cardiologists face challenges with borderline ventricles in congenital heart disease (CHD). This review aims to clarify when a ventricle is too small or large enough for surgical decisions.

Area of Science:

  • Pediatric Cardiology
  • Congenital Heart Disease
  • Cardiac Surgery

Background:

  • Borderline ventricles present diagnostic uncertainty in supporting systemic or pulmonary circulation.
  • Congenital heart diseases (CHDs) frequently involve underdeveloped left or right ventricles.
  • Current management lacks specific guidelines, leading to variable surgical approaches.

Purpose of the Study:

  • To define criteria for assessing borderline ventricles in pediatric CHD.
  • To aid clinicians in deciding between single-ventricle and biventricular surgical strategies.
  • To improve long-term patient outcomes by optimizing surgical approach.

Main Methods:

  • Literature review on ventricular size and function in CHD.
  • Analysis of existing data on single-ventricle versus biventricular outcomes.
  • Discussion of factors influencing surgical decision-making.

Main Results:

  • Identification of key parameters for evaluating borderline ventricular adequacy.
  • Highlighting the controversy and variability in current surgical management.
  • Emphasizing the critical impact of this decision on lifelong patient health.

Conclusions:

  • Establishing clearer guidelines for borderline ventricles is crucial.
  • Standardizing surgical approaches can improve consistency and outcomes.
  • Informed decision-making is vital for patients with CHD and borderline ventricles.
