A typical case of anginal syndrome in a fifty year old male has been described. The underlying lesion was congenital coronary arterio-venous fistula between the left anterior descending branch of the left coronary artery and pulmonary artery. Diagnosis has been made by coronary angiography and proved at operation. The patient underwent successful operation where a multiple fistulous ostia draining into the pulmonary trunk were obliterated by means of extracorporeal circulation. The pertinent literature related to this congenital anomaly and symptomatology has been reviewed.

Surgical treatment of infants with a large ventricular septal defect (VSD) unresponsive to medical therapy is sometimes indicated. Pulmonary artery banding originally described by Muller in 19521 has proven to be an adequate operation for controlling high pulmonary flow. In the past, a two staged procedure consisting of pulmonary artery banding followed by debanding and VSD closure has been used.2 More recently primary closure during infancy using deep hypothermia has been advocated.3 We have reviewed the results of debanding and VSD closure in an attempt to set a standard with which to compare primary closure which we now use.

A Grade II/VI systolic murmur was heard in the second and third intercostal spaces at the left sternal edge. The second heart sound was loud at the pulmonic area. The ECG showed right ventricular hypertrophy. On the chest x-rays, the heart appeared slightly enlarged and an increase in pulmonary vascular markings could be noted. Cardiac catheterization data is given in Table I. The cineangiograms (Fig. 1) established the diagnosis of simple transposition of the great arteries.

Four cases of Arterial Emboli are reported. Association is suggested be tween peripheral arterial emboli and malignant disease. No definite mecha nism for this association has been established but a malignancy-induced alteration of the clotting mechanism is postulated. In any general hospital, peripheral arterial embolization is not an uncom mon event. Immediate therapy since the introduction of the Fogarty catheter, has become fairly standardized and has been very successful in salvaging ischemic limbs. The long-range outlook, however, is dependent on the identification of the source of emboli and the institution of appropriate corrective or preventive measures. In many clinical reviews of peripheral arterial embolization, the probable source of the embolus could be reasonably established in 90% of the cases. Nevertheless, in each series there remains 10% of cases in which no source of embolus could be identified. 1 Over the past two years at The Memorial Hospital we have accumulated a series of patients with peripheral arterial embolization and all of whom had proven malignancies. We are presenting this series as a postulated causative association between peripheral arterial embolization and the malignant state.

Complications of coronary artery surgery were analyzed in a prospective controlled study of 150 patients, one group receiving methylprednisolone before temporary cardiopulmonary bypass. The patient population was comparable in both the groups. The number of deaths were the same in both the groups, myocardial infarction and cardiac arrhythmias were definitely lower in the Solu-Medrol group. Cerebral vascular accidents were higher in the control group and there were none in the drug treated group. Incidences of pulmonary embolism was reduced by the drug. Oxygen consumption by the tissues was higher in the Solu-Medrol treated group. There were no known complications of the drug, such as stress ulcer and infection. One patient did receive prophylactic antibiotics. Solu-Medrol was deliberately given in patients who were known to have uncomplicated duodenal ulcer. Post-operative bleeding in patients with duodenal ulcer was not noted. This could be explained due to the short acting nature of Solu-Medrol. We feel that Solu-Medrol does minimize serious sequelae of heart-lung machine in coronary artery surgery.

Seven different suture materials were evaluated in a standard rabbit aortotomy model as to infectability. Two monofilament sutures were found to have the lowest infection rate on the suture line as compared to multifilament material. It is assumed that this result is on the basis of the physical properties of the suture material. Infection of vascular anastomeses is an extremely serious complication. In 1971, the ten year experience of this Center was reported. The overall attack rate was low (0.25%) which represented 15 infections in 5,988 vascular procedures. However, of the 15 infected anastomoses 11 patients died a mortality of 73%. The most common etiologic agent in these infections was Staphylococ-

A patient with a rare case of cardiac tumor in the right atrium secondary to Wilms' tumor of the right kidney, underwent open heart surgery and removal of the mass was presented. This is the 10th. case of intracardiac tumor secondary to renal malignancy. Careful auscultation of the heart is necessary in patients with malignancy in the kidney to detect the possible right heart metastases through the inferior vena cava. Cardiac symptoms precede the renal manifestations in most cases. Malignant renal metastases to the heart should always be in mind in space occupying masses of the right heart chambers.

Intermittent claudication in the young is unusual. The most common cause is premature atherosclerosis; however, conditions such as thromboangitis obliterans, embolism, trauma, cystic disease of the adventitia or popliteal artery entrapment are diagnostic considerations. Entrapment of the popliteal artery by an anomalous muscle attachment or fibrotic band may result in external compression of the popliteal artery. Such compression can cause acute ischemia, and over a period of time the artery may develop irreversible changes secondary to repeated trauma. Certain aspects of the symptoms complex may serve to alert one of the possible presence of the popliteal artery entrapment syndrome. The following case is illustrative.
