[The incomplete atrio-ventricular canal. Operative and long term results in 100 cases (author's transl)].

100 patients with endocardial cushion defect of the partial type underwent surgical correction between the years 1957-1975. The age of patients ranged from 3 to 57 years with a mean of 18 years. In 89 patients there was a mitral insufficiency. The repair of the mitral valve was performed in 78 patients; in 21 was repaired also the tricuspidal valve. The hospital mortality was of 8 patients. The mortality was correlated with the age of the patients, the pulmonary pressure and with the presence of malformations of the tricuspid valve. A major complication was represented by a complete atrioventricular block that occurred in 8 patients, in 5 of these the block disappeared before the dimission from the hospital. 86 patients have been followed for a period variable from 2 to 228 months and an average of 61 months. The late mortality was of 4 patients. Two patients have been reoperated of mitral valve replacement because of residual important mitral insufficiency. The phonocardiographic study, done in 50 patients, showed a presence of a holosystolic murmur in 20. The standard X-ray chest and electrocardiogram iid not show important changes between the pre and post operative examination.

[Comparative evaluation of the isometric test and of dynamic exercise in the diagnosis of coronary insufficiency (author's transl)].

Fifty patients with exertional coronary insufficiency performed an exercise test on a bicycle-ergometer and an isometric exercise with an instrument set up by the authors with the collaboration of the technical laboratory of the hospital. All cases had EKG positivity during dynamic exercise and only 2 patients had a positive EKG answer during isometric exercise. Angina occured in 70% of cases during dynamic exercise and in 12% of cases during isometric exercise. The difference in the increasing heart rate of the two types of exercise was statistically significant, as was the difference between absolute values of heart rate reached at the end of the exercise. The difference in the values of arterial pressure reached in the two types of exercise was also statistically significant. Moreover the comparison of product heart rate, time arterial pressure, time 10(-2) bordered on statistical significance. 31 of the 50 patients who underwent coronary angiography, demonstrated severe impairment. During isometric exercise a higher percentage of disturbances was observed. The authors came to the conclusion that isometric exercise is not advisable for the diagnosis of coronary insufficiency, either for the low specificity or the potential risk.

[Influence of left anterior hemiblock on electrocardiographic indices of left ventricular hypertrophy (author's transl)].

The influence of left anterior hemiblock (LAH) on some electrocardiographic criteria of left ventricular hypertrophy (LVH) was investigated. 131 subjects were studied: 34 of them were normal (control group); 30 were carriers of isolated LAH; 38 were carriers of isolated LVH; 29 showed a pattern of combined LVH and LAH. The maximal voltages of QRS waves in leads usually analyzed for LVH, the QRS duration and the time of onset of the intrinsicoid deflection were compared among the groups. The specificity, the sensitivity and the performance of some LVH criteria were examined as well. LAH has been shown to conceal LVH on precordial leads, while it tends to make LVH more manifest on limb leads. The Romhilt and Estes' point score system proved to be the least affected by LAH. On the grounds of theoretical considerations and of empirical trials, we suggest modifying the Romhilt and Estes' point score system; furthermore we suggest modifying Sokolow's and Grant's criteria only when LAH is present. Such modified criteria have improved the accuracy of LVH prevision.

[Immediate and late arrhythmia in patients operated on for tetralogy of Fallot].

UNLABELLED: Arrhythmias are a frequent complication after repair of tetralogy of Fallot (TOF). We present our experience with 97 patients with special consideration for early and late hyperkynetic arrhythmias. The most frequent, 4% of the patients, was in junctional tachycardia. Late arrhythmias can be atrial or ventricular. The incidence of ventricular arrhythmias in the literature range from 42 to 82%. In the Authors experience multiforme ventricular ectopy was present in 80% of the patients, 20 years after surgery. We suggest an exercise test and averaging ECG in all the patients. Thirty six percent of patients with supraventricular tachycardia were symptomatic. CONCLUSION: as the incidence of arrhythmias after correction of TOF is high, it is very important to periodically reassess these patients. Antiarrhythmic treatment is indicated in all symptomatic patients, especially in those with major arrhythmias (SVT, AF and VT).
