[1] [2] Thermal ablation methods can damage the esophagus, phrenic nerve, and coronary vessels (as high as 5% [8]), which are spared by PFA. [1] One study showed an overall complication rate of 0.7% for PFA and no occurrence of phrenic nerve, esophageal, or pulmonary vein injury. [9]

Infection - infections can occur at the catheter insertion site or in the heart tissue. Patients require additional treatment if infection is a complication.
This variant may predispose the phrenic nerve to injury during subclavian vascular cannulation. In addition, an accessory phrenic nerve is commonly identified, present in up to 75% of a cadaveric study. [3] In canines, the phrenic nerve arises from C5-C7 with occasional small contributions from C4. [4]
Diaphragmatic paradox may be caused by weakening of inspiratory muscles due to injury, pyopneumothorax (collection of pus and excess air inside pleural cavity) or hydropneumothorax (collection of watery fluid and excess air inside pleural cavity). Also caused due to phrenic nerve injury caused during cardiac surgery, radiation, trauma, etc ...
Kehr's sign is a classic example of referred pain: irritation of the diaphragm is signaled by the phrenic nerve as pain in the area above the collarbone. This is because the supraclavicular nerves have the same cervical nerves origin as the phrenic nerve, C3, C4, and C5. [citation needed]

The phrenic nerve is then isolated under the scalenus anticus muscle. For the thoracic surgical technique, a small (~5 cm) incisions over the 2nd or 3rd intercostal space. The electrodes are placed around the phrenic nerves alongside the pericardium. The use of a thorascope allows for this technique to be performed in a minimally-invasive ...
