[Aneurysmectomy and aortocoronary bypass. Immediate and long-term results of 56 patients].

56 pts. who underwent left ventricular aneurismectomy were studied. Clinical improvement and lat post-operatory mortality rate have been evaluated. 39 pts. (II group) also had aortocoronary bypass and other surgical procedures performed at the time of the aneurismectomy. Group I (no other surgery beside the aneurismectomy) and group II did not significant differences in the pre-operatory period and were, therefore, comparable. The total operatory mortality has been of 14% (17.6% in group I and 12.8% in group II). By using myocardial protection the mortality dropped to 5.8%. A significant difference between deceased and survived pts. was noted in the following parameters: cardiac index, A-V oxygen difference, extracorporeal circulation time and the number of diseased coronary arteries (P < 0.001-0.005). Only 2 pts., both in group II, had a late death. After the operation 32 pts. became asymptomatic. Five pts. remained symptomatic: 3 continued to complain of angina and 2 to show signs of left ventricular failure; ventricular arrhythmias were still present in 6 pts. post-operatively (compared to 16 pts. pre-op.). The data suggested that aneurismectomy, associated with aorto-coronary bypass and myocardial protection, has an acceptable operatory risk, particulary in pts. with a good residual ventricular function. Except for ventricular arrhythmias clinical results are very good and late mortality rate is low

Complete atrioventricular canal associated with conotruncal malformations: anatomical observations in 13 specimens.

Conotruncal anomalies associated with atrioventricular (AV) canal defects are more common than is generally appreciated on clinical grounds. Among 39 specimens of AV canal malformations, 13 (33%) presented with conotruncal abnormalities: a complete form of AV canal has been observed in all. 5 cases exhibited visceral situs solitus, 5 situs ambiguus with asplenia and 3 situs ambiguus with polysplenia. In the first group, conotruncal anomalies were tetralogy of Fallot in 3 cases, bilateral conus with double outlet right ventricle (DORV) in 2, one with subpulmonary ventricular septal defect (VSD) and the other with doubly commited VSD. Survival in these patients was relatively longer (average 20 mth) and the clinical course was mainly determined by the degree of the pulmonary outflow obstruction: surgical correction should have been feasible in these cases. Patients with situs ambiguus, both with asplenia and polysplenia, had further severe cardiovascular malformations associated with AV canal which led to early death (average survival 12 days): anomalous pulmonary and systemic venous return and univentricular hearts. In the latter patients, tetralogy of Fallot, bilateral conus with DORV and pulmonary atresia were the conotruncal malformation. Retrospectively, in no case of the last category a complete repair had been accomplished. All but one specimen presented the complete form of AV canal with 'free floating anterior leaflet' and hypoplastic anterior tricuspid component. This hypoplasia could be interpreted as missing conal tissue in the development of the anterior tricuspid cusp. For this leaflet a dual embryological origin, both from the dextro-dorsal conal ridge and the right lateral AV cushion, is suggested.

[Transposition of the great arteries: anatomic types of left ventricular outflow tract obstruction (author's transl)].

A postmortem investigation has been carried out in 48 heart specimens with transposition of the great arteries (TGA) to evaluate incidence and type of left ventricular outflow tract obstruction. The frequence of pulmonary stenosis in our series (23%) is similar to those reported from previous studies. Cases have been divided in two groups according to presence or absence of ventricular septal defect. In cases with intact ventricular septum the obstruction was determined by asymmetric hypertrophy of the septum (1 observation) and by abnormal attachement of clefted anterior mitral leaflet to the interventricular septum (2 observations). In the specimens with ventricular septal defect, 4 presented a stenosis due to malalignment of the infundibular septum, associated with valvular stenosis in 1 case and with valvular stenosis and fibrous subvalvular ring in 2. Another case presented a stenotic pulmonary valve and a parachute mitral valve. The remaining 3 showed a cleft of the anterior leaflet of the mitral valve. The high incidence of infundibular malalignment obstruction is underlined together with its association with A-P or L-position of the aorta. This peculiar relation of the great arteries could be angiocardiographically employed as indicative for the presence of this type of left outflow tract obstruction in TGA.

[Removal of an endocavitary electrode with cardiopulmonary bypass for septicemia associated with right atrial thrombosis. Report of a case (author's transl)].

A case of staphylococcus epidermidis endocarditis associated with a right atrial thrombosis around a pacemaker electrode is presented. Stuce the antibiotic therapy had proved uneffective, the electrode had to be removed with cardiopulmonary bypass; the infection was subsequently eliminated. When a foreign body cannot be removed by closed techniques, open heart surgery with cardiopulmonary bypass may be necessary.

[The total anomalous pulmonary venous connection: pathophysiological, clinical and surgical aspects. Observations on 10 cases (author's transl)].

Ten cases of total abnormal pulmonary venous connection are described: 5 cases with supracardiac drainage, 4 with sub-diaphragmatic drainage and one with intracardiac drainage, 3 cases with supradiaphragmatic drainage, and 4 with subdiaphragmatic drainage have undergone surgical treatment. Some developmental, embryological and pathophysiological signs of this malformation are reported. The more significant clinical and instrumental data arising from our personal cases and from review data are discussed. In the clinical description a distinction is made between cases with venous obstruction and those without venous obstruction. The importance of hemodinamic tests, which allow us to identify the type of connection present, and whether or not there are associated malformations, are underlined. The natural history is conditioned by the presence of venous obstruction, by the value of the pulmonary hyper-flow and by the possibility of communication between the two circulatory districts. The prognosis of the cases with marked obstruction, and of those with irreversible cardiac failure is one of rapid deterioration: surgical correction in the first months of life is the only therapeutic possibility, even if the death risk is high. The cases without venous obstruction, and with fairly normal weight and circulation, are corrected surgically at a later age with much more favourable results.

The usefulness of the phonocardiography in the diagnosis of the extrinsic obstruction of the pulmonary artery. Report of a case (author's transl).

The Authors describe a case in which an anterior mediastinal tumor manifested as a cardiovascular disease. Phonocardiographic findings and their modifications induced by respiratory manoeuvres are presented and discussed. Particular enphasis is given to the disappearance, with deep inspiration, of the pulmonary ejection murmur associated with the simultaneous paradoxical behaviour of pulmonary component of the second sound. The Authors suggest that such findings can be indicative of pulmonary outflow obstruction by an external mass.

[The coarctation of the aorta in the adults. Long term results over 10 years (author's transl)].

From May 1964 through December 1976, at the Department of Cardiovascular Surgery, University of Padova, Medical School, 148 patients underwent surgery for coarctation of the aorta; 62 of them where 18 years of age or older. The Authors deal particularly with the clinical symptoms, the operative findings, the surgical technique and the postoperative complications of their series. The early (only three operative deaths) and late results are considered satisfactory, and are discussed according particularly to the type of surgical intervention.
