Surgical and electrophysiological considerations in the management of a patient with a subcutaneous implantable cardioverter-defibrillator undergoing coronary artery bypass surgery

One Indication for an Extravascular Cardiac Resynchronization Therapy Defibrillator: Lessons from a Combination Therapy Case with Epicardial Cardiac Resynchronization Therapy and a Subcutaneous Implantable Cardioverter Defibrillator

Extravascular cardiac resynchronization therapy (CRT) defibrillators (CRT-Ds) are ideal for recurrent blood stream infections. Furthermore, CRT is useful for patients intolerant to right ventricular (RV) pacing. The case was a 65-year-old man with a CRT-D who presented with a blood stream infection. Because he was hemodynamically unstable with temporary RV pacing, an epicardial CRT device was re-implanted concomitantly through a surgical procedure. After the operation, a subcutaneous implantable cardioverter defibrillator (S-ICD) was placed. However, not all pacing is eligible for S-ICD screening. Combination therapy with an epicardial CRT device and S-ICD might be an alternate option for cardiac surgery cases.
