This podcast episode discusses Patent Foramen Ovale (PFO) and its relation to high altitude, featuring Dr. Carlos Rojas, a thoracic radiologist.
Here's a summary of the key points with timestamps:
00:00:59 - What PFO is: A common condition where a flap between the heart's atria doesn't close after birth.00:01:38 - Symptoms: Can range from asymptomatic to shortness of breath, fatigue, and exercise intolerance, particularly at high altitudes [00:01:18]. Those with PFO are more susceptible to high-altitude symptoms. Mechanism at high altitude: Low oxygen (hypoxia) can cause pulmonary vasoconstriction, increasing pressure in the right ventricle [00:04:39].
Diagnosis: Methods like hypoxic simulation testing with echocardiography [00:07:51] and hypoxic cardiac MRI [00:12:57] are used to evaluate the heart under low oxygen conditions and detect shunting.
Treatment: Percutaneous closure is a procedure to close the PFO/ASD [00:22:20].
Other topics mentioned: Embryology and anatomy of the interatrial septum [00:14:49] and MRI room zones [00:26:16].
