ICD-10: Q22.6

Hypoplastic Right Heart Syndrome (HRHS) is a complex congenital heart defect characterized by underdevelopment of the right side of the heart. This condition significantly impacts the heart's ability to pump blood effectively, leading to various clinical challenges. Below is a detailed overview of HRHS, including its clinical description, associated features, and relevant ICD-10 coding information.

Clinical Description of Hypoplastic Right Heart Syndrome

Definition and Pathophysiology

Hypoplastic Right Heart Syndrome is defined by the inadequate development of the right ventricle, which may include the right atrium, tricuspid valve, and pulmonary artery. This underdevelopment results in a reduced capacity for the right heart to receive and pump blood to the lungs, leading to systemic and pulmonary circulation issues. The condition is often associated with other congenital heart defects, such as atrial septal defects or patent ductus arteriosus, which can complicate the clinical picture.

Symptoms and Clinical Presentation

Infants with HRHS typically present with symptoms shortly after birth, which may include:
- Cyanosis: A bluish tint to the skin, lips, and nails due to low oxygen levels in the blood.
- Difficulty Breathing: Rapid or labored breathing as the body struggles to receive adequate oxygen.
- Poor Feeding: Infants may have difficulty feeding due to fatigue and respiratory distress.
- Lethargy: Reduced activity levels and responsiveness.

Diagnosis

Diagnosis of HRHS is primarily achieved through:
- Echocardiography: This imaging technique is crucial for visualizing the heart's structure and function, confirming the diagnosis of HRHS.
- Chest X-ray: May show signs of heart enlargement or pulmonary congestion.
- Cardiac MRI: In some cases, MRI may be used for detailed anatomical assessment.

Treatment Options

Management of HRHS typically involves a multi-faceted approach, including:
- Surgical Interventions: Procedures such as the Norwood procedure, Glenn procedure, and Fontan procedure are often performed in stages to improve blood flow and oxygenation.

This condition poses significant challenges in terms of management and treatment. Below, we explore the standard treatment approaches for HRHS, including surgical interventions, medical management, and supportive care.

Surgical Interventions

1. Palliative Surgery

In many cases, the initial approach to HRHS involves palliative surgical procedures aimed at improving blood flow and oxygenation. The most common procedures include:

• Norwood Procedure: This is typically the first surgery performed in neonates with HRHS. It involves reconstructing the aorta and creating a connection between the right ventricle and the aorta, allowing for systemic blood flow. This procedure is usually performed within the first week of life[8].

• Glenn Procedure: This is often performed at around 4 to 6 months of age. It involves connecting the superior vena cava directly to the pulmonary artery, allowing blood from the upper body to flow to the lungs without passing through the heart[8].

• Fontan Procedure: Typically performed when the child is between 18 months and 4 years old, this procedure connects the inferior vena cava to the pulmonary artery, allowing for efficient blood flow to the lungs. The Fontan procedure is considered a definitive surgical treatment for HRHS, although it does not restore normal heart function[8].

2. Heart Transplantation

In cases where surgical interventions are not successful or if the heart function deteriorates significantly, heart transplantation may be considered. This option is typically reserved for patients who do not respond well to other treatments and have severe heart failure symptoms[8].

Medical Management
