What symptoms will damaged phrenic nerves cause?
The diagnosis of phrenic nerve injury requires high suspicion due to nonspecific signs and symptoms including unexplained shortness of breath, recurrent pneumonia, anxiety, insomnia, morning headache, excessive daytime somnolence, orthopnea, fatigue, and difficulty weaning from mechanical ventilation.
What happens when the phrenic nerve is damaged?
When the phrenic nerve is injured, the electrical signals in it stop traveling from the brain to the diaphragm muscle. The diaphragm muscle turns off and the patient may have difficulty breathing.
What causes elevated left hemidiaphragm?
Distention of the stomach, abdominal tumors, distended abdomen, subphrenic abscess, splenomegaly, or colon malrotation can present as elevated left hemidiaphragm. Elevated hemidiaphragm may occur secondary to pneumoperitoneum from a ruptured stomach or colon where free air becomes trapped under the diaphragm.
How to treat phrenic nerve damage in the heart?
1) Diaphragmatic Plication- tack that diaphragm down so that it doesn’t cause so much pressure, but that is not a fix to the problem, and it would eliminate any other treatment options down the road. 2) Put in a Diaphragm Pacer, similar to a pace maker for the heart.
What happens when the phrenic nerve is paralyzed on both sides?
When the phrenic nerve is paralyzed only on one side (right or left), the patient may have enough diaphragm movement on the other side to breathe adequately. When the phrenic nerve is paralyzed on both sides (right and left), the diaphragm stops moving altogether and the patient cannot breathe on their own.
Is the phrenic nerve on the right side dead?
He has 56% lung function currently. After all other possible issues were ruled out, a phrenic nerve conduction study was done and concluded that in fact, the phrenic nerve on his right side was indeed, dead. There is no function in the right diaphragm.
Where does the phrenic nerve control the diaphragm?
What is Phrenic Nerve Paralysis? The phrenic nerve controls the diaphragm, which is the major muscle for breathing. Three major nerves (given the symbols C3, C4, C5) exit from the spinal cord in the neck and combine to form the phrenic nerve. Right and left phrenic nerves travel between the lung and heart to power each side of the diaphragm.

Can a phrenic nerve injury cause radiofrequency ablation?
The second most common scenario of phrenic nerve injury is during electrical isolation of the superior vena cava using point-by-point radiofrequency ablation. Very rarely, ablation at the roof of the left atrial appendage can result in left phrenic nerve damage. A number of strategies have been employed to prevent phrenic nerve injury.

Is the phrenic nerve injury a complication of AF?
Phrenic nerve injury is a well-established complication of all types of atrial fibrillation (AF) ablation and is most common with balloon-based approaches, writes Hugh Calkins (Baltimore, USA) for Cardiac Rhythm News.
