[A case of ischemic dilated cardiomyopathy, mitral regurgitation and congestive heart failure successfully treated by Batista operation, coronary artery bypass grafting and mitral valve replacement; usefulness of myocardial scintigraphy].
A 75-year-old man diagnosed as having ischemic dilated cardiomyopathy, congestive heart failure and mitral regurgitation underwent left ventricle volume reduction operation (Batista), coronary bypass grafting and mitral valve replacement because myocardial infarction had developed at lateral, inferior and small area of apex wall, not at interventricular septum. Left ventricular endodiastolic volume index and left ventricular endosystolic volume index decreased from pre-operative values of 155, and 128 ml/m2 to post-operative values of 113, and 82 ml/m2, respectively. Left ventricular ejection fraction increased from a pre-operative value of 17% to a post-operative value of 27%. This evaluation was performed by myocardial scintigraphy (quantitative gated spect: QGS). This method was bloodless and useful for determination of indication of left ventricle volume reduction surgery including Batista operation and pre- and post-operative evaluation of this type of surgery. Today, Batista operation is, generally speaking, performed for non-ischemic dilated cardiomyopathy. In this case, however, Batista operation was applied to ischemic dilated cardiomyopathy and was very effective.
