Balloonvalvuloplastie
Balloon valvuloplasty is a minimally invasive medical procedure used to widen narrowed heart valves. It is primarily employed to treat valvular stenosis, a condition where a heart valve's leaflets become stiff and fused, restricting blood flow. The procedure involves inserting a thin, flexible tube called a catheter into a blood vessel, typically in the groin or arm, and guiding it to the affected heart valve. A deflated balloon is positioned at the site of the narrowed valve. Once in place, the balloon is inflated, stretching the valve leaflets and widening the opening. The balloon is then deflated and removed along with the catheter. Balloon valvuloplasty is most commonly used for mitral stenosis, aortic stenosis, and pulmonary stenosis, particularly in infants and children, and in adults who are not candidates for surgical valve repair or replacement. While it can provide symptomatic relief and improve blood flow, it may not always be a permanent solution, and restenosis (re-narrowing) can occur over time. The success and longevity of the procedure depend on factors such as the severity of the stenosis and the specific valve involved.
