For the first time: defibrillator with sternum electrode implanted

In Germany, approximately 65,000 people die each year from sudden cardiac arrest caused by cardiovascular diseases, according to the German Heart Foundation. Sudden cardiac arrest is often triggered by a rapid cardiac arrhythmia in the main ventricles, known as ventricular fibrillation. Without immediate treatment, it leads to circulatory arrest within minutes. Individuals with heart failure are especially at risk and benefit from early intervention.   

Implantable cardioverter-defibrillators (ICDs) are well-established devices for preventing sudden cardiac arrest. These systems consist of a defibrillator and one or more cable-shaped electrodes placed below the collarbone, guided into the heart via a large vein and anchored there.   

The ICD monitor heart rhythms, the defibrillator emits either weak impulses or an electric shock to correct dangerous arrhythmias. Following implantation, ICDs can be programmed and monitored externally via specialized equipment in clinics or practices.   

The Aurora System, approved for therapy in Europe, differs fundamentally from traditional defibrillators.   

"The Aurora system is a so-called extravascular system. The electrode, which is normally anchored in the heart, is guided below the sternum and lies on the heart. The defibrillator itself is inserted under the left armpit. In the rare event of an infection, this cannot enter the bloodstream directly, as the Aurora system is not placed in the heart. This is a great advantage for patients," explains Dr. Leonard Bergau, Deputy Head of the Clinical Electrophysiology Unit and Senior Physician at the UMG's Department of Cardiology and Pneumology.  

Prof. Karl Toischer, Head (acting) of the Clinic for Cardiology and Pneumology at the UMG adds, "Of course, we decide which system is most suitable on an individual basis and depending on the clinical picture together with the patient."   

• Gentler Procedure: The placement of the electrode outside the heart lowers the risk of injuries such as lung perforation.
• Simpler Replacement: Faulty electrodes can be replaced without direct intervention on the heart.   
• Suitability for Specific Patient Groups: For dialysis patients, where conventional vascular access may be critical, the system offers a valuable alternative.
