Abstract:The usual technique of transventricular mitral commissurotomy involves serial enlargement of an apical left ventriculotomy wound with the help of Hegar dilators to facilitate introduction of a Tubbs dilator which has a broad tip. We have designed a modified Tubbs dilator with a tapered tip which serves as a one-pass instrument for dilating both ventriculotomy wound and mitral valve. It also allows easy probing of severely stenosed mitral valve orifices under digital control.
Keywords:dilatation    equipment design    heart surgery    mitral valve    mitral valve stenosis
