We evaluated the efficacy of automated lamellar therapeutic keratoplasty (ALTK SystemÂ®; Moria/Microtek Inc., Doylestown, Pennsylvania, USA) in the treatment of various corneal disorders affecting the anterior to mid-stroma.
Whatâs the problem? Pulmonary regurgitation (PR, also called pulmonic regurgitation) is a leaky pulmonary valve. This valve helps control the flow of blood passing from the heart to the lungs. A leaky pulmonary valve allows blood to flow back into the heart chamber before it gets to the lungs for oxygen.
Complicated: A 'heart murmur means that one can hear blood flow with a stethoscope. Very nonspecific term. A hole in the heart is a connection between the circulation that supplies the lungs (right heart) and the circulation that supplies the body (left heart). There are various types of holes (defects). All of the holes/defects have the potential to cause a murmur.
