One hundred and twenty patients undergoing aortocoronary bypass procedures were randomly placed into control and digitalized groups. All were initially in normal sinus rhythm and without evidence of congestive heart failure. Supraventricular arrhythmias occurred in 17 of 66 controls and in only three of 54 digitalized patients (P < 0.01). There was no evidence of digitalis toxicity. Based on this evidence we recommend prophylactic digitalization for patients having aortocoronary bypass operations.

Abstract A patient with incapacitating recurrent supraventricular tachycardia, refractory to medical management, was evaluated for possible surgical intervention. Several types of competitive artificial pacemakers were considered, as was surgical section of the His bundle plus conventional pacing. The patient was treated with a competitive, radio-frequency-coupled atrial pacemaker, which she herself operates to break her supraventricular tachycardias. The device has operated successfully on numerous occasions for over 15 months. Several other aspects of this patients arrhythmias were discussed.

Results of gas endarterectomy of the right coronary artery were evaluated in 29 consecutive patients. There were one surgical and two early postsurgical deaths. All three had postmortem examination, and in two there was occlusion of the gas endarterectomy. Five patients did not have repeat catheterization. Twenty-one patients were completely re-evaluated and had repeat cardiac catheterization one to sixteen months after surgery (mean eight months). Ten patients (Group A) had gas endarterectomy without a saphenous vein graft to the right coronary artery. Only one patient had significant vessel patency. Eleven patients (Group B) had the combined procedure of a saphenous vein graft anastomosed to the segment of artery that had the endarterectomy. There was excellent graft patency in seven patients (64%) and good distal flow into the segment that had endarterectomy in six of the seven patients. In conclusion, gas endarterectomy is not of value unless it can be combined with a saphenous vein graft to provide good flow to the distal vessel that had endarterectomy. Results with the combined procedure suggest that even with a severely diseased artery, gas endarterectomy can often provide continuing distal runoff for the graft.

Two patients developed severe vascular collapse after left ventriculography with organic iodides. Hemodynamic monitoring showed marked reduction in systemic pressures. In one patient there was no response to the standard therapeutic measures in anaphylactic reactions, and prompt response to fluid administration was obtained. In the second patient response was prompt to fluids, adrenalin, and hydrocortisone.

Twenty-three patients underwent left ventricular aneurysmectomy without coronary artery bypass or other surgical procedure. Fourteen patients (Group 1) benefitted from surgery, and nine fared poorly (Group 2), including the four postoperative deaths. Among the 19 survivors, 17 had postoperative catheterizations. Pre- and postoperative left ventriculograms in the right anterior oblique projection were analyzed by planimetry of the aneurysmal and non-aneurysmal areas. This method provided data favorably altered by surgery in the improved patients and unchanged in the others. None of the preoperative ventriculographic measurements effectively separated the postoperative patient groups. The poor results in the Group 2 patients were of heterogeneous origin arising from pre-, peri- and postoperative factors. The more important factors were the largest and smallest aneurysms, surgically induced mitral insufficiency, and progressive coronary artery disease. Thus, the improvement in surgical results from better angiographic preoperative case selection is possible, but limited.

Most ventricular aneurysms result from transmural myocardial infarction and are located in the left ventricle. Right ventricular aneurysms are unusual, and their origin at times is obscure. A patient with two discrete right ventricular aneurysms is reported. The literature on operative excision of right ventricular aneurysms is reviewed, and the various etiological factors are discussed.

A case of paradoxical embolism is presented in which the antemortem diagnosis was facilitated by a new simple angiographic technique that demonstrated a patent foramen ovale. An additional 14 patients were studied by this technique, and one had a patent foramen ovale. The mechanism of reversal of the normal intraatrial pressure gradient and subsequent right to left shunt through a patent foramen ovale is discussed. This angiographic technique may be readily applied in any diagnostic catheterization laboratory and complements existing methods for detecting patency of the foramen ovale in patients with suspected paradoxidal embolism.
