Summary
Congenital diaphragmatic hernia (CDH) repair patients show lasting right ventricular (RV) function differences. Echocardiography reveals impaired RV diastolic and systolic waves and reduced strain in repaired CDH patients years later.
Area of Science:
- Pediatric Cardiology
- Congenital Heart Disease
- Cardiac Imaging
Background:
- Congenital diaphragmatic hernia (CDH) can lead to abnormal lung development and negatively impact right ventricular (RV) function.
- Persistent RV dysfunction may affect long-term cardiac health in CDH survivors.
Purpose of the Study:
- To investigate persistent echocardiographic differences in RV function in patients who underwent CDH repair compared to control subjects.
- To assess long-term cardiac outcomes in pediatric CDH survivors.
Main Methods:
- Recruitment of patients with a history of CDH repair and age-matched controls.
- Evaluation of RV function using strain analysis and tissue Doppler imaging (TDI).
- Statistical analysis using Wilcoxon's rank-sum test.
Main Results:
- No significant age difference between CDH (n=7) and control (n=16) groups.
- CDH patients exhibited significantly lower RV early diastolic wave (12.8±1.5 cm/s vs. 16.1±3.1 cm/s) and RV systolic wave (10.2±0.8 cm/s vs. 13.4±1.3 cm/s) via TDI.
- Lower interventricular apical septal strain (-20.1±4.6% vs. -25.4±4.1%) and a trend towards lower global RV strain (-27.8±3.0% vs. -31.1±3.1%) in CDH patients.
Conclusions:
- Patients repaired for CDH demonstrate persistent alterations in RV function years post-surgery.
- Further follow-up is crucial to understand the long-term impact of these RV functional differences on adult CDH survivors.

Mitral Regurgitation I: Introduction
Mitral regurgitation is characterized by the backward circulation of blood from the left ventricle to the left atrium during systole, a phase of the cardiac cycle when the heart contracts and pumps blood out of the chambers. This abnormal flow occurs primarily due to the dysfunction of the mitral valve or its supporting structures, which include the mitral leaflets, chordae tendineae, annulus, and papillary muscles.Etiology and Mechanisms:Primary Mitral Regurgitation: This type arises from...
Mitral Stenosis I: Introduction
Mitral Valve Stenosis (MVS) is a heart condition where the mitral valve narrows, impeding blood circulation from the left atrium to the left ventricle. The etiology and pathophysiology of this condition are multifaceted, leading to a cascade of cardiovascular complications.Causes of Mitral Valve StenosisRheumatic Heart Disease: It is the main cause of mitral valve stenosis, particularly in developing nations. This condition arises from rheumatic fever, an inflammatory illness resulting from...
Cardiomyopathy III: Hypertrophic Cardiomyopathy
Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...
Mitral Stenosis II: Clinical features and Diagnostic Tests
Mitral stenosis is a heart condition in which the mitral valve, which allows blood to flow from the left atrium to the left ventricle, becomes narrowed or stenotic. This narrowing hinders blood flow and leads to clinical symptoms requiring specific medical evaluations and management strategies. The following overview outlines the clinical symptoms, assessments, diagnostic findings, prevention methods, and treatments for mitral stenosis.Clinical ManifestationsDyspnea (shortness of breath): This...
