Experience with fifty repeat procedures for myocardial revascularization.

Fifty coronary reoperations were performed in 49 patients. The reasons for the operations were occluded or stenotic grafts in 23 patients, an inadequate first operation in 13, progression of coronary atherosclerosis in 3, and combinations of these reasons in 11. Mediastinal adhesions made the operations difficult and produced hazards. Six patients died from the operation. Seven surgical mishaps occurred, including damage to five functioning grafts from the previous operation and laceration of two ventricles. Nine patients had less than complete operations because angiographically demonstrated targets could not be found. Repeat angiography was performed on 9 of the surviving patients. Ten of the 14 new or revised grafts were found to be functioning. Although a repeat operation is more difficult technically and carries additional risks as compared with a first operation, the indications are thought to be the same for both first and secondary revascularization procedures. The increased risks of the repeat operations are compelling arguments to strive for complete revascularization at an initial operation in order to avoid the necessity of the second one.

Pacemaker therapy in children with complete heart block.

Permanent pacemaker therapy in children with complete heart block is necessary occasionally. Ten patients ranging in age from 8 months to 15 years were treated with an implanted P-wave, synchronous epicardial pacemaker. Indications for implantation were persisting postsurgical heart block, congestive failure, syncopal attacks, and arrhythmias. There were two deaths not attributed to pacemaker malfunction. The remaining eight children have been followed up for 38 to 108 months. There have been 27 pulse generator replacements. Twenty-three were for battery exhaustion, three for electromechanical failure, and one was due to arrhythmia. Rhythm disturbances have occurred on eight occasions. There have been no infections. It is concluded that the implanted P-wave synchronous pacemaker is an effective method of therapy when indicated for children with complete heart block.

An assessment of Mustard's operation as a palliative procedure for transposition of the great vessels.

Ten patients in whom palliative Mustard operations have been performed for transposition of the great vessels with ventricular septal defect and elevated pulmonary vascular resistance are reported. There has been early or late mortality in this group of patients, and postoperative morbidity has been minimal. Five of them have been recatheterized, and the results indicate substantial improvement in postoperative arterial oxygen saturation with change in pulmonary vascular resistance. The operation is reserved for those patients in whom peripheral desaturation is the major cause of symptomatology. Clinical improvement has been gratifying, and the continued use of the operation in selected patients seen indicated.

Long-term survival in bronchogenic carcinoma.

In this report, we shall review the clinical and pathological features of 64 patients who survived 10 years or longer after resection for bronchogenic carcinoma. Most of these patients had either adenocarcinoma or bronchioloalveolar carcinoma. None of them had oat cell carcinoma. In many of the long-term survivors, there were pathological findings generally considered to indicate a poor chance for survival. Thus we believe that curative resection for bronchogenic carcinoma should be attempted whenever feasible to offer the patient every hope of long-term survival.
