Left ventricle has certain size and dimensions since birth and acquire adult proportions over the years. However ,when a wall is weakened by either by a scar or an ischemia, the pressure dynamics tend to stretch its fibers either locally or as a whole. If it affects generally, it gets dilated . If it is affected locally, start as akinetic segment , then a paradoxically acting segment and a final bulge called aneurysm which will be filled with a clot. This certainly affects the overall pumping function of the heart
A bulge of the heart is called aneurysm and can be well corrected by surgery. Generalised dilatation have also been tried to be corrected by surgeries , but with unsatisfactory results.
These set of surgeries are called left ventricular modification surgeries.
WHAT IS DORR'S PROCDURE?
The operation where the bulge on the left ventricle is cut, opening into the bulge suture secured and attaining normal shape and funtion is achieved , is called Dorr's operation.
IS THE OPERATION RISKIER THAN THE BYPASS OPERATION?
This operation carries the same risk as high risk bypass operation. Usually patients get discharged on 7 th day.
