Biventricular pacemakers can help with mitral valve leakage

12th December 2016

Biventricular pacemakers can reduce mitral regurgitation in people with dilated cardiomyopathy, improving the symptoms of heart failure and people’s ability to exercise, says a new study from Spain.

Mitral regurgitation is the leakage of blood backwards through the mitral valve from one chamber of the heart to another each time the heart contracts. The mitral valve controls blood flow from the left atrium to the left ventricle.

Biventricular pacing

Mitral regurgitation is common in people whose hearts do not pump well. So the research team looked at using cardiac resynchronisation therapy (a biventricular pacemaker) in people with symptoms including moderate to severe mitral regurgitation and left ventricle pumping problems.

The study, published on the European Society of Cardiology website, concluded that use of the pacemaker can control and even improve the basic cause of the disease.

The researchers included Dr Ivan Keituqwa Yañez, consultant in intensive care medicine and cardiac pacing. University Hospital Rafael Mendez in Murcia.
