Remote programming of cardiac implantable electronic devices: A novel approach to program cardiac devices for magnetic resonance imaging.

BACKGROUND: Magnetic resonance imaging (MRI) in patients with MRI-conditional cardiovascular implantable electronic devices (CIED) remain a logistical issue for device programming during the scan. In current practice, a trained person needs to be present on-site to program CIED for MRI scan. This can cause delay in patient care, rescheduling of tests and increase healthcare costs. A novel remote programming (RP) strategy can be utilized to reprogram the CIED remotely. We sought to explore the feasibility and safety of RP of CIEDs in patients undergoing MRI scan. METHODS: We implemented the Medtronic CIED RP software at our institution after ensuring HIPAA compliance. The MRI technician started the session by contacting an off-site remote operator and placing a programmer wand from the 2090 Medtronic programmer over the CIED. The remote operator logged into a remote access software and provided a unique access code to the MRI technician. After entering the access code into the programmer, the remote operator was able to program the device as needed. We conducted a periodic audit of the first 209 patients who underwent RP of CIEDs for MRI. Outcomes analyzed were successful completion of RP sessions and time saved per scan. RESULTS: Of the 209 MRI scans, 51 scans were performed urgently. There were no connectivity and programming problems or need for MRI rescheduling. In-person reprogramming was not required for any patient. All scans were completed safely in a timely manner, and there were no reports of CIED malfunction. Time saved per scan was estimated to be 28 ± 10 min. CONCLUSIONS: Remote programming of CIEDs for MRI scans is a safe and effective strategy.

A Rare Case of Pulmonary Embolism in a Patient With Interrupted Inferior Vena Cava and Polysplenia.

Interrupted inferior vena cava (IVC) with azygos continuation is one of the anomalies of the inferior vena cava (AIVCs) where venous drainage of the lower extremities is accomplished through a dilated azygos system and is usually accompanied by other congenital malformations such as polysplenia. AIVCs are more common in patients younger than 40 presenting with deep venous thrombosis (DVT). However, pulmonary embolism (PE) in association with AIVCs remains underreported. In this article, we describe a rare case of a 23-year-old male who presented with syncope secondary to sub-massive pulmonary embolism in the setting of an interrupted vena cava draining directly into the azygous vein.
