[Azygos or hemiazygos continuation of the inferior vena cava. An angiographic findings of 10 cases (author's transl)].

The angiographic findings of 10 cases with azygos (AC) or hemiazygos (HC) continuation of the inferior vena cava (IVC), associated with other congenital heart disease (0.5%), are described. Abdominal situs solitus was present in 7 cases, left isomerism in 3. In 5 cases IVC was to the left to the spine, bilateral in one. In 6 cases there was AC, HC in 2; in one both types of continuation were documented. It is important that this venous anomaly be diagnosed before cardiac catheterization; manipulation of the probe may be very difficult when saphenous approach is used. The correct use of the terms "Azygos", "Hemiazygos" and "Accessory Hemiazygos" are discussed.

[Traumatic tricuspid insufficiency. Clinical and therapeutic aspects. Report of three cases (author's transl)].

Three cases of traumatic tricuspid insufficiency are reported. The most consistent clinical and noninvasive cardiovascular findings were: previous nonpenetrating thorax trauma; non holosystolic murmur which increased slightly during inspiration on standing; electrocardiographic patterns of right atrial enlargement and right bundle branch block; unusual bulge along the mid-left heart border, seen on chest x-ray examination suggesting ventricular aneurysm; striking right ventricular dilatation wit paradoxical movement of the ventricular septum on ECHO. Cardiac catheterization led to definitive diagnosis by demonstrating a massive tricuspid valve incompetence with "ventricularisation" of the right atrial pressure. Some dyskinetic areas of the right ventrice, most likely due to the full-thickness contusion of the miocardial wall, seen on the right cineangiography, confirmed the diagnosis. The long-term clinical and haemodynamic follow-up was useful for monitoring the evolution of the disease. Surgery should be recommended in the presence of right-sided heart failure not relieved by adequate medical treatment, in view of the low operative risk.

[Ischemic alterations of the regional mechanical performance of the left ventricle. Study of parietal deformation as a vectorial time-dependent parameter and of pressure-length loops (author's transl)].

A study was carried out on 59 patients with significant stenosis (greater than or equal to 75%) in at least one coronary vessel. For each parietal region of the left ventricle the pattern of contraction was defined through a study of the regional deformation as vectorial time-dependent parameter and of the construction of the pressure-length loops. The different models obtained in basal conditions and through intervention (nitroglycerin and post-extrasystolic potentiation) were correlated with experimental data on ischemic alterations of the regional mechanical performance.

[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

[Atrial myxoma. Clinical, diagnostic, surgical and pathological features of 13 subjects (author's transl)].

The clinical, surgical and pathological features of 13 patients (3 males, 10 females) with cardiac myxoma are reported. Eleven masses were situated in the left atrium and 2 in the right one. The incidence of signs and symptoms usually ascribed to cardiac myxoma is evaluated. Particular emphasis is given to embolization phenomenon which occurred in 3 patients with villous-surfaced tumors. The results of phonocardiographic, echocardiographic and isotopic angioscintigraphic examination are illustrated and the use of these incruent investigations is highly recommanded. Final diagnosis may be achieved by cardiac catheterization and angiocardiography. Successful surgical excision was carried out in 12 patients. Structural profile of atrial myxoma is discussed. Particular attention is given to the surface of the tumors (smooth or villous), to the pseudovascular structures on the light microscopy and to the endotelial like features, together with secretory activity of the myxoma cells, on the electron microscopy. The morphologic findings support the neoplastic origin of the myxoma. The distinction between embolization and malignant metastasis is underlined.

[Correlations between the patterns--dynamic--of regional contraction and the ECG-enzymatic-clinical signs of myocardial infarction (author's transl)].

60 patients with clinical signs of coronary artery disease who had a hemodynamic examination were studied. The study of the regional dynamics using the deformation as a vectorial time-dependent parameter and the pressure-length loops, was carried out on a total of 420 parietal regions of the left ventricle: the basal ventriculography, the post-extrasystolic potentiation and the ventriculography after nitroglycerin were evaluated. The dynamic regional pattern was correlated with clinical-enzimatic signs of necrosis in the electrocardiogram. The possibility of correlating signs of necrosis with particular patterns of hypokinesia, akinesia, dyskinesia which differ from corresponding "static" forms of asynergy in active pressure development and deformation (even in a brief systolic interval) seems to confirm the physiopathologic interpretation of the regional phenomenon based on the ratio between viable not viable myocardium -- as primary cause.

[Aortic insufficiency associated with interventricular communication. Natural history, angiographic diagnosis and surgical approach].

Clinical, electrocardiographic, radiological, hemodynamic and angiocardiographic data of 12 patients with ventricular septal defect (VSD) associated to aortic regurgitation (AR) have been analyzed. The trend of evolution of the AR has been evaluated and angiographic criteria to make a correct diagnosis have been pointed out. Nine patients have been followed up for a mean of 3.8 years. The severity of AR seemed to increase only in three cases: this demonstrates that AR associated to VSD is not always a progressive disease. The usefulness of various radiological views in evidencing the anatomy of both VSD and aortic valve has been discussed and findings of left ventriculogram and aortogram are detailedly described. The site of VSD and the type of lesion of the aortic valve may be crucial for indicating surgical intervention and its type. Indication for surgery is briefly discussed. Surgical technics are shortly summarized.
