[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.

[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.

[Anomalous muscle band of the right ventricle. Part II: Report of six cases associated to other cardiac congenital malformations (author's transl)].

Six cases of anomalous muscle band of the right ventricle associated to other cardiac congenital malformations are described. In five of them ventricular septum defect was present; in one aortic valvular stenosis with supravalvular diaphragm, plus right pulmonary artery stenosis. Modification in pathophysiology of ventricular septum defect due to the obstacle represents by the anomalous muscle band in the right ventricle are discussed in detail. In every case corrected diagnosis was suggested by right ventricle angiography.

[Clinical and angiographic observations in aneurysm of the membranous septum. Pathologenetic implications].

Aneurysm-like kialations of the membranous septum are described with increasing frequency in association to a ventricular septal defect (VSD). Their etiology may be congenital, though with different pathogenesis and acquired. An anatomical distinction between true aneurysm of the membranous septum and pseudoaneurysm is proposed. The acquired forms may be joined to a decrease of left to right shunt and are regarded as the mechanism of closure of a VSD. Nine cases of aneurysm-like dilation of the membranous septum are presented: an interpretation of their etiology and pathogenesis is discussed, on the basis of the history and clinical and instrumental data.
