Artificial intelligence–based method predicts risk of atrial fibrillation

19/11/2021

Atrial fibrillation—an irregular and often rapid heart rate—is a common condition that often leads to the formation of clots in the heart that can travel to the brain to cause a stroke. A researchers team has developed an artificial intelligence–based method for identifying patients who are at risk for developing atrial fibrillation and could therefore benefit from preventative measures.

Preventing calcification of bioprosthetic heart valves

03/11/2021

A defective heart valve is the second most common form of heart disease. Most cases involve a narrowed aortic valve, but often the mitral valve can also be affected. Prostheses significantly increase the life expectancy of those with the disease. While bioprosthetic heart valves have some advantages over mechanical ones, they can become calcified relatively quickly.

Identifying risks before surgery - with simple means

08/10/2021

Risks during surgery, especially cardiological risks, are still very high in the Western world. However, conventional methods for measuring such risks before surgery are costly or even not always meaningful. And increasing economization in hospitals also makes it more difficult for staff to find time for a comprehensive pre-op analysis.

Medical imaging: obtaining an accurate view of blood vessels for surgery

02/08/2021

Surgical intervention is often inevitable when blood vessels become narrowed, blocked, or damaged. Surgeons use stents and medical balloons to open and widen the arteries, suck out the obstructing clots and use a catheter to examine the vessels. Intraoperative cardiovascular imaging is an essential tool to guide the catheters and instruments during the minimally invasive procedures.

Cardiovascular diseases: using AI to navigate the catheter

09/03/2020

Treatment of a heart attack or stroke caused by vascular occlusion must be prompt to prevent further damage to vital tissue. Unfortunately, the actual treatment is often preceded by a lengthy catheter-based procedure where the cardiologist manually guides the catheter to the affected vessel. AI might perform this task in the future.

Cardiac diagnostics – prompt and personalized

08/11/2019

If physicians suspect an acute myocardial infarction, they first order an ECG. This test is very established and allows cardiologists to quickly diagnose acute heart attacks – though the test does not detect less common heart attack symptoms. So far, those patients had to wait up to twelve hours before a heart attack could be accurately diagnosed or ruled out. But things are about the change.
