Pulmonary edema is not directly caused by right ventricular failure.
Solución
Pulmonary edema, which is the accumulation of fluid in the alveoli, is primarily associated with left ventricular failure rather than isolated right ventricular (RV) failure.
Explanation of Each Option:
-
Liver margin palpable two finger breadths below the right costal margin: In RV failure, there is systemic venous congestion which can cause hepatomegaly (enlarged liver), making the liver margin more palpable.
-
Swelling of the lower extremities: RV failure leads to increased venous pressure, resulting in peripheral edema, especially in the lower extremities.
-
Pulmonary edema (fluid in the alveoli): This is typically a consequence of left ventricular failure, where the left heart cannot effectively pump blood out to the body, causing a backlog of blood in the pulmonary circulation and fluid leakage into the alveoli.
-
Distension of the jugular veins of the neck: RV failure causes elevated central venous pressure, which manifests as jugular venous distension (JVD).
Conclusion: Among the listed abnormalities, pulmonary edema is not a direct result of isolated right ventricular failure.
Answer: Pulmonary edema (fluid in the alveoli) is not directly caused by right ventricular failure.

Pulmonary edema (fluid in the alveoli) is not a direct result of right ventricular failure. Instead, it is primarily associated with left ventricular failure, where the heart’s inability to pump effectively leads to fluid backing up into the lungs. Right ventricular failure typically causes systemic symptoms, such as the distension of jugular veins, liver congestion, and swelling of the lower extremities due to poor venous return.
When it comes to managing right ventricular failure, it’s important to monitor for signs like peripheral edema and elevated jugular venous pressure. Additionally, patients might benefit from diuretics to manage fluid overload in the body. Understanding the interrelation of the heart’s chambers can lead to better treatment strategies and minimize misdiagnosis!
