In this report, we shall analyze the results obtained with palliative treatment in 30 patients with congenital heart disease who were operated upon at the University Hospital of Caracas during the period 1968 to 1972. In all cases, an ascending aorta-right pulmonary artery anastomosis was performed. Although we believe that the Blalock-Taussig and Potts shunt are satisfactory operations in some cases, at the present time we prefer the aorta-right pulmonary branch anastomosis in Fallots tetralogy and other congenital heart diseases such as single ventricle. In Fallot's tetralogy, particularly, this procedure provides better results, because the anastomosis can be closed through the aorta when these patients are later subjected to total correction with extracorporeal circulation.

With the advent of cardiac catheterization, cardioangiography, and selective coronary arteriography, specific types of cardiac disease can be recognized and clearly defined. This is appropriate because myocardial biopsy alone rarely plays a major role in cardiac diagnosis. Excluding Aschoff's nodules in patients with rheumatic valve disease, the light microscopic findings in patients with rheumatic heart disease, congenital heart disease, pericardial disease, hypertensive and arteriosclerotic heart disease are similar and nonspecific. In these, interstitial fibrosis and/or myocardial hypertrophy is the dominant tissue diagnosis. Occasionally a pericardial and myocardial specimen is helpful to distinguish constrictive pericarditis and restrictive cardiomyopathy. Myocardial biopsy has provided the only method for diagnosis in a small number of patients with normal hemodynamics, normal coronary arteriograms and normal ventriculograms. The patients were studied because of chest pain and/or cardiac arrhythmias. Supraventricular and/or ventricular arrhythmias were encountered. In these patients the tissue diagnosis was interstital fibrosis and/or myocardial hypertrophy. These findings are consistent with primary myocardial disease which was not recognized clinically or by angiographic studies. The procedure seems to play a major role in the diagnosis of specific types of primary myocardial disease. It is valuable in the recognition of glycogen storage disease, amyloidosis, hemochromatosis, and myocarditis. On the basis of current experience, the indications for myocardial biopsies depend on the need for a tissue diagnosis in determining the management of the patient and the availability of adequately trained personnel to perform the procedure and manage the complications.

Small doses of isoprenaline sulphate given intermittently produce a characteristic cardiopathy consisting of subendocardial scarring and myocardial hypertrophy. A morphometric technique was successfully applied to the quantitation of these changes. This technique improves the use of the isoprenaline model for the study of cardiac necrosis as statistical analysis can be applied and objective comparisons made. No hypertrophy was seen in the absence of myocardial necrosis which suggests that it is at least in part compensatory.

Within the spectrum of neonatal congenital cyanotic heart disease, emergent surgery is often necessary to correct profound pulmonary hypoperfusion. An ascending aorto-to-pulmonary artery anastomosis (Waterston-Cooley) has proved to be the preferred procedure in selected patients. A new technique to correct the occasional resultant pulmonary arterial deformity is presented which is performed concomitantly with definitive intracardiac correction.

To evaluate the benefits of operative treatment of congenital heart disease in older age groups, a clinical study on patients over 40 years of age with atrial septal defect was carried out. The series consisted of 125 consecutive patients operated on between 1966 and 1974. There were 8 cases with a primum, 12 cases with a sinus venosus type of secundum and 105 cases with a simple secundum defect. The operative mortality was 2 patients (1.6%). It was due to myocardial infarction in one case and high pulmonary vascular resistance in the other. On re-examination 3-6 months postoperatively, 107 patients were improved, 13 patients unchanged and 3 patients were worse than before operation. On re-evaluation after an average period of 6 years, 88 patients were still improved. 32 patients unchanged and 3 patients were worse compared with their pre-operative status. On the basis of the results and the previous reports on atrial septal defect without operation, the surgical correction of ASD even in older age groups can be recommended. The problem of deterioration of some patients, despite a good immediate postoperative result, is discussed.

Myocardial injury during a variety of cardiac surgical operations was determined in 57 patients by serial electrocardiograms (ECG's), serial determinations of serum creatine phosphokinase (CPK), and perioperative and postoperative technetium-99m stannous pyrophosphate (PYP) scans. ECG evidence of injury developed in four patients, whereas positive localized injury by PYP scan developed in ten. Twenty-one patients had elevated CPK enzymes postoperatively. The localization of injury by PYP scan correlated with ECG evidence of infarction in only one of four patients. Localized left ventricular injury by PYP scan without new Q waves on the ECG was common (5/12) in patients undergoing aortic valve replacement with perfusion of the coronary arteries. The injury in patients with congenital heart disease occurred at sites of ventricular incision or suggested possible air embolization of the coronary arteries. Perioperative infarction is frequently segmental and nontransmural and occurs in patients with coronary, valvular, and congenital heart disease.

Three patients with the rare anomaly of congenital absence of the ostium of the left main coronary artery are presented. In two of the patients, aged 50 and 52 respectively, the diagnosis was established during selective coronary cineangiography for a severe anginal syndrome. The third patient, a 16-year-old-girl, underwent cardiac catheterization for investigation of a congenital heart malformation, when a single right coronary artery was demonstrated with absence of the main coronary artery ostium. Two patients underwent successful aortocoronary bypass grafting. In view of the occurrence of sudden death and massive myocardial infarction in adult patients shown to have severe or complete obstruction of the left main coronary artery, it is suggested that adult patients with this condition, who require open-heart surgery for any other cardiac disorder, should undergo aortocoronary bypass grafting concurrently even prior to the development of anginal symptoms. Children shown to have this anomaly should be subjected to long-term follow-up and have an aortocoronary bypass graft performed when symptoms of coronary insufficiency develop.

Problems associated with the early evolution of corrective operation (septation) for univentricular heart (single or common ventricle) are illustrated in a total experience of 36 such operations, 30 of which were recent. Complete heart block existed preoperatively in five of the 30 patients and developed at operation in another 10; only two of these 15 patients attained a satisfactory result. Associated pulmonary stenosis was present in 16 patients, and this seemed to influence the result favorably. An extracardiac conduit between the right-sided ventricular chamber and the distal pulmonary trunk was employed in 20 patients. The presence of associated anomalies, including function of the atrioventricular valves in seven, had a highly unfavorable influence on the result. Although all seven of the most favorable candidates attained a satisfactory result, only 13 (43 percent) in the total group of 30 attained a satisfactory result. Further evolution of this operation, as in previous operations for complex congenital heart disease, should provide more results that are satisfactory.

Survival after cardiac transplantation has improved significantly over the past 3 1/2 years at our Center as compared to previous experience (Fig. 5). Currently, survival rates for 60 patients who have had heart transplantation since late in 1973 (program year mean survival +/- S.E.) are 66 percent (+/- 6.6 S.E.), 63 percent (+/- 7.0) and 58 percent (+/- 8.2) 1, 2, and 3 years after operation, respectively. In this report the major reasons for this successful trend have been summarized. These consist of transvenous endomyocardial biopsy for diagnosis and management of graft rejection, use of RATG, immunologic monitoring for early detection of impending rejection, and cardiac retransplantation in selected cases. The present expectations for survival and rehabilitation after heart transplantation are fully comparable to the current results of renal transplantation from unrelated donors. These considerations support the inclusion of cardiac transplantation as a realistic therapeutic alternative in the management of patients with advanced heart disease irremediable by standard forms of treatment.

Real-time two-dimensional visualization of cardiac anatomy has been a major advance in the noninvasive evaluation of congenital heart disease. Performed from precordial or suprasternal notch sites, the techniques allow noninvasive evaluation of the cardiac chambers, atrioventricular valves, and great arteries for the diagnosis of common and complex forms of congenital heart disease. Two-dimensional real-time echocardiography, therefore, can be expected to become an integral part of the noninvasive diagnosis and serial followup of children and infants with congenital heart disease.
