To examine the association between exercise-induced LVOT gradients and LA strain with increased cardiac events, such as heart failure and arrhythmias, in children with hypertrophic cardiomyopathy (HCM).
Key Findings:
LVOT gradients and LA strain are important indicators of cardiac events in children with HCM, suggesting a potential predictive role for these parameters.
LA strain parameters were analyzed to assess atrial function and predict adverse cardiac outcomes, highlighting their clinical relevance.
Interpretation:
The study aims to clarify the relationship between LVOT gradients, LA strain, and cardiac events in pediatric HCM patients, an area with limited existing data.
Limitations:
Single-center study may limit generalizability, as results may not be applicable to other populations.
Retrospective design may introduce selection bias, potentially affecting the reliability of the findings.
Conclusion:
Further research is needed to validate findings and understand the implications of LVOT gradients and LA strain in pediatric HCM, particularly in diverse populations and with larger sample sizes.
