While I have no quarrel with the elegant intraoperative studies done by Bandyk and associates, I feel that pulsed Doppler spectral analysis may not be available to the average community hospital surgeon, and I feel it is redundant if proper attention is given to the techniques of this procedure. We perform our operation with a modified Hall valvulotome and have recognized no residual or retained valves during surgery or in the early postoperative period in 61 consecutive cases. Our patients are followed up at three-month intervals, and we did recognize a hypertrophied valve causing hemodynamic disturbances at the one-year mark in one patient. Indeed, this hypertrophied valve was detected with a simple bidirectional Doppler transducer and was explored and excised, and the graft was
