Pulmonary Hypertension: Classification and Pathogenesis01:30

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...
Atelectasis II: Pathophysiology01:10

Atelectasis II: Pathophysiology

Atelectasis develops when alveoli lose their air and collapse inward. Because lung tissue is naturally elastic, these air sacs shrink rather than remaining open. Collapsed alveoli are no longer ventilated, reducing their role in gas exchange. Blood flow may continue in these regions, creating a ventilation–perfusion mismatch. Clinical findings include decreased breath sounds, dullness to percussion, reduced chest expansion, and decreased tactile fremitus as sound transmission through collapsed...
Other Pulmonary Disorders01:17

Other Pulmonary Disorders

Respiratory disorders encompass a range of conditions with varying levels of severity. Asthma, marked by chronic airway inflammation and hypersensitivity, is one such condition. It can lead to airway obstruction due to factors like bronchial spasms, mucosal edema, increased mucus secretion, or epithelial damage. Asthma triggers are diverse, ranging from allergens to emotional upset, and treatment focuses on both immediate relief through bronchodilators and long-term inflammation suppression.
Mitral Stenosis II: Clinical features and Diagnostic Tests01:23

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...
Pneumothorax II: Pathophysiology01:08

Pneumothorax II: Pathophysiology

Pneumothorax means the presence of air in the pleural space — the thin potential gap between the visceral and parietal pleura. This condition disrupts the normal pressure balance that keeps the lungs inflated, leading to partial or complete collapse of the affected lung.Normal physiologyUnder normal conditions, the pleural space maintains a slightly negative intrapleural pressure, which keeps the lungs expanded against the chest wall. This negative pressure creates a delicate balance between...
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...

Summary

This case study highlights late-diagnosed pulmonary agenesis in a 51-year-old female presenting with progressive dyspnea. Despite severe dextroscoliosis, the patient shows good survival due to mild, stable pulmonary hypertension.

Area of Science:

  • Cardiology
  • Pulmonology
  • Radiology

Background:

  • Pulmonary agenesis is a rare congenital anomaly.
  • Late diagnosis is uncommon, especially presenting with progressive dyspnea and dextroscoliosis.

Observation:

  • A 51-year-old female with severe dextroscoliosis presented with progressive dyspnea.
  • Imaging revealed opacification of the left thorax, mediastinal deviation, and absence of left lung structures.
  • CT confirmed absence of left pulmonary artery and airways; bronchoscopy was non-diagnostic for the left main bronchus.

Findings:

  • The patient was diagnosed with left pulmonary agenesis.
  • Echocardiography showed mild pulmonary hypertension (33 mmHg) with right heart dilatation but preserved cardiac function.
  • Polycythemia was noted in blood samples.

Implications:

  • This case demonstrates a rare presentation of pulmonary agenesis with late diagnosis.
  • The patient exhibits modest functional cardiologic implications and limited therapeutic options.
  • Good survival is attributed to the late onset and low severity of pulmonary hypertension.
