Insights

This review covers pediatric pulmonary hypertension, focusing on left-to-right shunting, bronchopulmonary dysplasia, and primary pulmonary hypertension. Effective treatments like nitric oxide and prostanoids are discussed for improved outcomes in children.

Area of Science:

  • Pediatric Cardiology
  • Pulmonology
  • Vascular Biology

Background:

  • Pediatric pulmonary hypertension (PPH) involves functional and morphological changes in pulmonary vessels.
  • Key conditions include left-to-right shunting, bronchopulmonary dysplasia, and primary pulmonary hypertension.
  • Pathogenesis involves an imbalance of vasoconstricting and vasodilating mechanisms.

Purpose of the Study:

  • To review current concepts in the pathogenesis of PPH in infants and children.
  • To discuss contemporary management strategies for PPH.
  • To highlight special considerations for left-to-right shunting, bronchopulmonary dysplasia, and primary pulmonary hypertension.

Main Methods:

  • Literature review of pathogenesis and management strategies for pediatric pulmonary hypertension.
  • Analysis of functional and morphological contributions to PPH.
  • Evaluation of current and emerging therapeutic interventions.

Main Results:

  • Nitric oxide is effective for PPH post-intra-cardiac repair with left-to-right shunting.
  • Prostanoids are under investigation for left-to-right shunting and effective for primary pulmonary hypertension.
  • Therapeutic strategies for PPH with bronchopulmonary dysplasia target chronic lung disease and utilize vasodilators.

Conclusions:

  • Targeted therapies based on pathophysiological understanding improve PPH management.
  • Further research is needed for primary pulmonary hypertension pathogenesis.
  • Prostanoids show promise for improving long-term prognosis in pediatric pulmonary hypertension.

Pulmonary Hypertension: Classification and Pathogenesis

Pulmonary hypertension (PH) is a severe health condition in which the mean pulmonary arterial pressure increases to 25 mmHg or more, even when the body is at rest. This high pressure in the blood vessels that transport blood from the heart to the lungs can cause various symptoms, including shortness of breath, can lead to right heart failure, and significantly affect the overall quality of life.
There are various classifications for PH, each relating to different underlying causes and also...

Treatment for Pulmonary Arterial Hypertension: Oxygen Therapy for Respiratory Failure

Oxygen therapy has emerged as a significant tool in enhancing the quality of life for patients suffering from pulmonary arterial hypertension (PAH). While this therapy has principally been studied on patients with significant hypoxemia, this therapeutic approach helps prevent potential organ damage and can be administered in the comfort of one's home.
Oxygen therapy is vital in increasing and maintaining blood oxygen levels in PAH patients. As a result, it aids in reducing fatigue, improving...
Pulmonary Cycle: Exhalation01:17

Pulmonary Cycle: Exhalation

In terms of human respiration, the act of expelling air, known as exhalation (or expiration), operates on the principle of pressure gradients. During expiration, the pressure within the lungs exceeds that of the surrounding atmosphere. Under normal conditions, quiet breathing involves passive exhalation and is free of muscular contractions. This is because the exhalation process is driven by the natural elastic recoil of the lungs and chest wall, both of which have an inherent tendency to...

Pulmonary Embolism I: Introduction

Pulmonary embolism (PE) occurs when a thrombus, fat or air embolus, amniotic fluid, or tumor tissue blocks one or more pulmonary arteries. These blockages originate in the venous system or the right side of the heart.EtiologyPE primarily arises from deep vein thrombosis (DVT) and other hypercoagulable states, such as inherited thrombophilias. Additional etiological factors include venous stasis, commonly seen in obesity, and endothelial injury from surgery and trauma. Less common causes include...
Chronic Obstructive Pulmonary Disease I: Introduction01:23

Chronic Obstructive Pulmonary Disease I: Introduction

Chronic obstructive pulmonary disease is a common, preventable, and treatable respiratory disorder characterized by persistent symptoms and progressive airflow limitation. This limitation results from a combination of small-airway disease (obstructive bronchiolitis) and parenchymal destruction (emphysema), both driven by chronic inflammation from exposure to harmful particles or gases.The disease includes two main pathological entities: emphysema, marked by destruction of alveolar walls and...
Pulmonary Embolism I: Introduction01:19

Pulmonary Embolism I: Introduction

A blood clot, or thrombus, is a semi-solid mass composed of fibrin, platelets, and red blood cells. When it forms within a vessel, it can obstruct blood flow, known as thrombosis. If part of the clot detaches, it becomes an embolus that can travel and block distant vessels. When this occurs in the pulmonary arteries, it causes a condition known as pulmonary embolism (PE).Origin and ImpactMost often, the embolus originates from a thrombus in the deep veins of the lower limbs, a condition called...
