Anomalous origin of left coronary artery with aortopulmonary window - a case report with surgical correction and delayed control.

A 9-month-old male baby was investigated for a massive left-to-right shunt at the arterial level. On right heart catheterization a patent ductus could not be demonstrated but retrograde arterial angiography showed an aorto-pulmonary window. During corrective surgery on cardiac bypass, the left coronary artery was found to arise from the aorto-pulmonary window, this was corrected by dividing the communication distal to the origin of the left coronary artery. On follow-up investigation 6 months after operation the baby was without symptoms and showed a fully functional left coronary artery. To our knowledge this is the first case of such a congenital anomaly to be described.

Delayed pulmonary thrombectomy via a peripheral approach in the treatment of pulmonary embolism and sequelae.

Delayed unilateral pulmonary embolectomy via the peripheral approach has been performed in 12 patients suffering from chronic pulmonary vascular obstruction after a single or repeated embolisms. Arterial hypoxemia and pulmonary hypertension were present in all cases. Embolectomy was performed several months or years after the initial event. There were 2 early and one late death. The surviving patients are doing well clinically and show definite hemodynamic and angiographic improvement.

[Aneurysm of the sinus of Valsalva rupturing into the pulmonary infundibulum. Echographic study].

Rupture of a Sinus of Valsalva aneurysm into the pulmonary infundibulum with ventricular septal defect was diagnosed by M mode echocardiography The differential diagnosis was prolapse of an aortic valve cusp associated with ventricular septal defect. The relevant features were the presence of an echo anterior to the anterior aortic wall. This echo was related to the aortic valve as a small posterior movement was recorded at aortic valve closure. Systolic fluttering of the pulmonary valve suggested a degree of subvalvular obstruction. Diastolic fluttering was related to the aortic regurgitation immediately below the pulmonary valve. This case confirms the hypothesis that the anterior echo produced by the aortic valve is in fact the left anterior coronary cusp.

[Aneurysm of the arteria lusoria. Clinical and diagnostic aspects. Postoperative results after resection and restoration of arterial continuity].

A 55 year old man, hypothyroid from previous thyroidectomy, presented with angina due to tracheal compression by a tumour of the posterior superior mediastinum. The preoperative work-up was negative. An aneurysm of a retrooesophageal subclavian artery was found at exploratory right thoracotomy in January 1977. This was resected and arterial reconstruction with a dacron graft was performed. The long term post operative clinical and angiographic results are satisfactory. The medical literature of this rare condition is reviewed.

[Unusual recording of a giant pulmonary A wave on echocardiography in pulmonary atresia with an intact septum].

An infant with cyanotic congenital heart disease underwent M mode echocardiography, cardiac catheterisation and angiography. A diagnosis of pulmonary atresia with intact ventricular septum was made. Echocardiography showed an average sized right ventricle with tricuspid valve thickening, as previously described in this condition. In the pulmonary incidence, a giant A wave, occuring after the P wave of the surface ECG, without a systolic valvular opening, was recorded. This probably corresponded to the motion of the diaphragm separating the pulmonary infundibulum from the true pulmonary artery. The possibility of recording the giant A wave of the fibrous diaphragm should be recalled in patients with pulmonary atresia with intact ventricular septum.

[Osler aortic aneurysm in isthmic coarctation. Clinical and angiographic aspects and postoperative results].

A case of probable infective aneurysm complicating isthmic coarctation of the aorta, is reported. On radiology, the aneurysmal mass seemed to have developed in less than two years. However, it was not possible to culture the causative organism. The pre- and postoperative angiographical appearance after one-stage radical surgery of the lesion and its complication are described.

[Aortic insufficiency and syphilitic coronary ostial disease. Pre- and postoperative angiographic aspects].

The authors report the case of a 50 year old patient with severe aortic incompetence (stage IV on angiography) and syphilitic left coronary ostial disease confirmed by complementary investigations. Management comprised aortic valve replacement and saphenous vein aorto-coronary bypass. The postoperative angiographic appearances showed normal valve function and a permeable aorto-left anterior descending bypass graft. The outcome was also satisfactory from the clinical point of view.

[Combined surgery of the cardiac valves and the coronary arties (author's transl)].

The authors report on an experiment with 17 cases, in which valvular substitution and bypass were combined. This type of operation carries a greater operative risk than that of separate operations, but a complete surgical correction can be obtained. The mortality rate diminishes with the improvement of the surgical team's experience.

[Myocardial infarct complicated by a posterior aneurysm of the left ventricle. Correction by resection and double coronary bypass. 1-year clinical and angiographic follow-up].

5 months after a posterior infarction, a man of 48 was found to have a posterior aneurysm with right coronary thrombosis and anterior inter-ventricular stenosis. A total treatment approach (resection of the aneurysm + double bypass graft) led to a stable clinical cure, which has been monitored one year later by ventriculography and coronary arteriography. The authors make the comment, however, that in this case surgery was more in the way of a safety measure than a necessity.

[Cardiac surgery in Jehovah's witnesses. Apropos of 47 cases].

47 cardiac defects in Jehova's witnesses were operated on without using any blood during the operation. In 9 cases the patients were under 15 years of age. 7 cases were of congenital heart defects in which the operation could be carried out with the heart still beating or by a closed heart technique: 4 of these were adults and 3 were children. In 40 cases, extracorporeal circulation was required: 19 valve defects, 8 coronary areterial cases, 10 congenital cardiac lesions, 2 valve defects associated with coronary artery disease, and 1 aneurysm of the thoracic aorta. Of these 40 patients, 4 died. The details and limits of this total haemodilution are analysed, as are the causes of failure and complications. This technique does not worsen the postoperative prognosis appreciably, but limits the scope of the surgery, and cannot be applied to a child of less than 10 kg.
