New hope for correcting irregular heartbeat

31.03.2003


Robert Wood Johnson University Hospital expands treatment options



People who suffer from irregular heartbeat now have a different treatment option, thanks to a new procedure being offered at Robert Wood Johnson University Hospital.
RWJUH is the first hospital in New Jersey and one of a few centers in the nation to offer patients the option of Microwave Ablation as a stand-alone procedure to eliminate atrial fibrillation, the most common form of irregular heartbeat.

Microwave Atrial Ablation is a minimally invasive technique in which a precise beam of microwave energy is applied to the source of the heart’s abnormal electrical activity that causes a cardiac arrhythmia, or irregular heartbeat.



During the procedure, a catheter is inserted through a two-inch incision to apply microwave energy to the left and right atria. This energy produces a discreet lesion to prevent the transfer of electrical signals.

“Patients who have failed conventional therapy and can tolerate general anesthesia with no other significant risk factors for surgery are eligible,” said Dr. Mark Anderson, Director of the Minimally Invasive Cardiac Surgical Program at Robert Wood Johnson University Hospital and Associate Professor of Surgery at UMDNJ-Robert Wood Johnson Medical School. “By now offering this as a stand-alone procedure, we hope to eliminate atrial fibrillation in a greater number of patients. Previously, Atrial Ablation was performed only in conjunction with other procedures, including Coronary Artery Bypass Surgery (CABG) and aortic and mitral valve surgeries.”

According to the American Heart Association, atrial fibrillation, found in 1-2 million Americans, occurs when the two small upper chambers of the heart, known as the atria, quiver instead of beating correctly. As a result, a blood clot may occur because the blood in the atria is not pumped out completely. A stroke may result if a part of the blood clot leaves the heart and gets stuck in an artery in the brain. Approximately 15% of strokes are caused this way.

Atrial fibrillation has a number of causes, including weak blood flow to the heart muscle, problems with the heart valves or damage to the heart from untreated high blood pressure. Other medical conditions can also cause atrial fibrillation. Thyroid problems, infection or lung disease can all lead to an irregular heartbeat.

Microwave Ablation is not the first treatment option for patients with atrial fibrillation. Initially, medication or electrical cardioversion (electric shock) are attempted, but in cases where these therapies are unsuccessful, Microwave Atrial Ablation may be considered.

Not everyone with atrial fibrillation may be aware of their condition, as symptoms do not usually appear until the heart rate increases to 150 beats per minute. These may include heart palpitations, shortness of breath, chest pain or an irregular pulse. Oppositely, atrial fibrillation may also cause the heart rate to decrease, showing symptoms of fatigue, dizziness or fainting.

Im Focus: OLED microdisplays in data glasses for improved human-machine interaction

The Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP has been developing various applications for OLED microdisplays based on organic semiconductors. By integrating the capabilities of an image sensor directly into the microdisplay, eye movements can be recorded by the smart glasses and utilized for guidance and control functions, as one example. The new design will be debuted at Augmented World Expo Europe (AWE) in Berlin at Booth B25, October 18th – 19th.

Im Focus: Complex hardmetal tools out of the 3D printer

For the first time, Fraunhofer IKTS shows additively manufactured hardmetal tools at WorldPM 2016 in Hamburg. Mechanical, chemical as well as a high heat resistance and extreme hardness are required from tools that are used in mechanical and automotive engineering or in plastics and building materials industry. Researchers at the Fraunhofer Institute for Ceramic Technologies and Systems IKTS in Dresden managed the production of complex hardmetal tools via 3D printing in a quality that are in no way inferior to conventionally produced high-performance tools.

Fraunhofer IKTS counts decades of proven expertise in the development of hardmetals. To date, reliable cutting, drilling, pressing and stamping tools made of...

Im Focus: Launch of New Industry Working Group for Process Control in Laser Material Processing

At AKL’16, the International Laser Technology Congress held in May this year, interest in the topic of process control was greater than expected. Appropriately, the event was also used to launch the Industry Working Group for Process Control in Laser Material Processing. The group provides a forum for representatives from industry and research to initiate pre-competitive projects and discuss issues such as standards, potential cost savings and feasibility.

In the age of industry 4.0, laser technology is firmly established within manufacturing. A wide variety of laser techniques – from USP ablation and additive...
