Insights

Alveolar capillary dysplasia with misalignment of pulmonary veins (ACD/MPV) is a rare, fatal lung disorder. This study reviews three cases, highlighting its typical presentation as treatment-resistant persistent pulmonary hypertension of the newborn.

Area of Science:

  • Pediatric Pulmonology
  • Developmental Biology
  • Medical Genetics

Background:

  • Alveolar capillary dysplasia with misalignment of pulmonary veins (ACD/MPV) is a rare and often fatal developmental lung disorder.
  • ACD/MPV typically manifests as persistent pulmonary hypertension of the newborn (PPHN) that is unresponsive to conventional treatments.

Purpose of the Study:

  • To present the clinical experience with three cases of ACD/MPV over a 15-year period.
  • To underscore the diagnostic challenges and clinical course of ACD/MPV.

Main Methods:

  • Retrospective case series review.
  • Analysis of clinical data from three neonates diagnosed with ACD/MPV.

Main Results:

  • All three cases presented with severe PPHN refractory to standard therapies.
  • The study details the clinical course and outcomes for these patients.

Conclusions:

  • ACD/MPV is a severe condition requiring high clinical suspicion.
  • Early recognition and potential future therapeutic strategies are critical for managing this disorder.

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...

Alveoli and Alveolar Ducts

The respiratory zone of the human body, which stands in contrast to the conducting zone, comprises the structures that actively participate in the exchange of gases. The initiation of this zone is marked by the terminal bronchioles converging into respiratory bronchioles, the tiniest bronchiole classification. The respiratory bronchioles give way to the alveolar ducts that opens into a congregation of alveoli. Actively involved in gas exchange, alveoli resemble tiny sacs similar to clusters of...

Mitral Valve Prolapse I: Introduction

IntroductionThe mitral valve, one of the heart's four valves, regulates blood flow. These valves have flaps that open and close to direct blood properly through the heart and body. During each heartbeat, the flaps open for blood to pass through and seal shut to prevent backflow. Specifically, the mitral valve opens to allow blood flow from the heart's upper left chamber to the lower left chamber. It then closes securely as the lower left chamber contracts to pump blood to the body, preventing...
