This channel includes news and new technology innovations for cardiac electrophysiology (EP) systems, techniques and devices using in EP labs. This includes implantable EP devices, pacemakers, implantable cardioverter defibrillators (ICD), cardiac resychronization therapy (CRT), ablation technologies, left atrial appendage (LAA) occlusion, atrial fibrilation (AF) and Holter monitors.
The most popular story in the month of January 2021 was on a small study that showed the new iPhone 12 can cause ICDs to stop functioning. COVID-19 content continues to rank among the top stories, including an article on the possible long-term cardiac consequences of COVID-19 infection in COVID long-haulers.
The Medicalgorithmics PocketECG Holter monitor offers real-time, remote, wireless ECG recording and tracking. Real-time data review may be able to help diagnose an arrhythmia quickly, reducing the amount of time the patient needs to be monitored. Also, 24/7 data offers a more complete picture of the patient's health, rather than fragments of data from older Holter and event monitor systems.
Medtronic's DiamondTemp Ablation (DTA) system is FDA cleared to treat patients with recurrent, symptomatic paroxysmal atrial fibrillation (AF) and who have been unresponsive to drug therapy. The DiamondTemp system is the first FDA-approved, temperature-controlled, irrigated radiofrequency (RF) ablation system with diamonds currently available to deliver ablations.
Patients with atrial fibrillation are at far greater risk of a catastrophic COVID outcomes, so steps should be taken to reduce AFib risks in addition to precautions against COVID like making, hand washing and social distancing. Images include an electromap from an AF ablation procedure and a COVID-19 from the CDC.
More complex, longer interventional procedures such as structural heart interventions or this revascularization of a coronary chronic total occlusion (CTO) at Henry Ford Hospital in Detroit, requires angiography imaging systems that have improved image detail and lower radiation dose. However, purchase of new systems was put on hold by many hospitals in 2020 due to the sudden drop in elective procedures and diversion of resources due to the COVID-19. Photo by Dave Fornell.
New cardiac monitoring technologies allow for longer duration data collection. The Medtronic Reveal Linq implantable cardiac monitor allows for 24/7 monitoring for up to three years. This might not be necessary for most patients, and there are several newer Holter monitors that can record up to several days or several weeks of data in real-time.

COVID-19 related topics by far out-paced all other topics in cardiology in 2020 on the DAIC website. Several stories topped the list related to the cardiovascular issues with hydroxychloroquine being used as a treatment for the virus. Top new device technologies in 2020 included European approval of the Abbott Tendyne transcatheter mitral valve, FDA approval of Medtronic's new Micra AV pill-sized pacemaker, and FDA clearance of the first drug-eluting stent with short-duration dual-antiplatelet therapy (DAPT).
An example of the new generation of inexpensive, wearable cardiac monitors that are seeing increased usage. This is the Cardiac Insight Cardea Solo device. After the monitoring period is over, the wearable patch is torn open to retrieve a data pod that is inserted into a reader to download the data. The software automatically creates reports based on the data, complete with waveforms for various cardiac measures.
