Conduction abnormalities after cardiac surgery are common as is spontaneous resolution of these abnormalities. However, 1%-3% of patients will require placement of a permanent pacemaker. Patients with preexisting conduction abnormalities, undergoing reoperation, preexisting pulmonary hypertension and undergoing mitral or aortic valve operations are at a higher risk for requiring a permanent pacemaker. We present the first case described in the literature of a patient with a preexisting left bundle branch block, and heart failure with a reduced left ventricular ejection fraction of 25% who developed complete heart block after placement of a coronary sinus catheter.

Complex regional pain syndrome is a chronic pain condition that may be resistant to many treatment modalities. Ketamine infusions have demonstrated some promising results, though their use may be associated with a number of adverse effects limiting their widespread applicability. ⋯ We report the impact of recurrent short subanesthetic ketamine infusions for the treatment of complex regional pain syndrome resulting in biliary dilation, jaundice, and cholangitis. We recommend that prescribing physicians consider this and monitor liver function tests throughout the treatment period to minimize morbidity.

The prevalence of neuromuscular diseases and peripheral neuropathies in veterans exposed to Agent Orange (AO) is particularly high. Pharmacologic management has not been effective for these patients. ⋯ We present a patient with AO-induced peripheral neuropathy who was successfully treated with burst SCS. To our knowledge, this is the first report describing the use of burst SCS for treatment of peripheral neuropathy related to AO exposure.
