Response to "Pulmonary Flow Management by Combination Therapy of Hemostatic Clipping and Balloon Angioplasty for Right Ventricular-Pulmonary Artery Shunt in Hypoplastic Left Heart Syndrome".

The article "Pulmonary Flow Management by Combination Therapy of Hemostatic Clipping and Balloon Angioplasty for Right Ventricular-Pulmonary Artery Shunt in Hypoplastic Left Heart Syndrome" offers valuable insights into Right Ventricular-Pulmonary Artery Shunt in Hypoplastic Left Heart Syndrome. This letter commends the study for its relevance and potential to improve patient care but highlights several limitations. Notably, the study overlooks the impact of Balloon angioplasty is a useful treatment for recoarctation in individuals with HLHS, but it frequently necessitates further operations.

Response to "Effect of Bedside Ultrasound‑Guided Versus Fluoroscopy‑Guided Transvenous Cardiac Temporary Pacing in Children with Bradyarrhythmia".

The article "Effect of Bedside Ultrasound‑Guided Versus Fluoroscopy‑Guided Transvenous Cardiac Temporary Pacing in Children with Bradyarrhythmia" offers valuable insights into comparative short-term pacing strategies for pediatric bradyarrhythmias. This letter commends the study for its relevance and potential to improve patient care but highlights several limitations. Notably, the study overlooks the impact of genetic factors on bradyarrhythmias and treatment outcomes, lacks detailed information on the influence of medications, and does not address the cost-effectiveness of the pacing techniques.
