[Role of bidimensional echocardiography in the study of aneurysms of a membranous septum associated with defects of the intraventricular septum of perimembranous type].

Spontaneous closure of ventricular septal defects (V.S.D.) is frequently associated with aneurysm of the membranous septum (A.M.S.). However, the presence of A.M.S. may not be always indicative of closure or diminution of the size of V.S.D.. The purpose of this paper is to present the role of two-dimensional echocardiography (2D E) in the identification and assessment of A.M.S.. The dimensions, morphology and motion of A.M.S. during the cardiac cycle was also analyzed frame by frame by the 2D E technique. 20 cases of A.M.S. associated with perimembranous V.S.D. are included in this study. The most useful echocardiographic section in the assessment of A.M.S. was the apical four-chamber view with slight cranial angulation (sensitivity = 100%). The frame-by-frame analysis of A.M.S. motion during the cardiac cycle may give useful informations concerning the hemodynamic and physiopathologic abnormalities associated with the underlying congenital heart diseases. We conclude the 2D E seems to be useful in the identification and assessment of A.M.S. associated with perimembranous V.S.D.

[Possibilities and difficulties of differential diagnosis by 2-dimensional echocardiography of mobile masses inside the right atrium. Apropos of a case].

A peculiar case of mobile right atrial mass thrombotic in origin identified by two-dimensional echocardiography is reported. By the characteristics of the mass and the negative history for SBE and malignant neoplasm, the possibilities of tricuspid vegetations or infiltration by an extracardiac tumor could be reasonably ruled out. On the other hand, a myxomatous mass could not be excluded in this case. The thrombotic nature of the mass was recognized at autopsy. The possibility to identify by two-dimensional echocardiography right atrial masses together with the difficulties in certain particular cases to recognize their nature are discussed.

Prospective identification of patients with amyloid heart disease by two-dimensional echocardiography.

The purpose of this study was to determine whether changes in myocardial wall echogenicity that suggest amyloid disease could be prospectively identified by a qualitative analysis of two-dimensional echocardiographic images. Two thousand seventy-eight consecutive echocardiograms obtained over a 14 month period were prospectively analyzed. The myocardial walls of 30 patients showed multiple, discrete, small highly refractive echoes; amyloid disease was not known or suspected in any of them. It was recommended that all 30 patients undergo gingival biopsy to confirm the diagnosis and biopsy was performed in 15 patients. The recommendation for biopsy was made only on the basis of two-dimensional echocardiographic images and was independent of findings regarding thickness of the walls or the dimensions of the cardiac chambers. Results of biopsy were positive in 11 patients and negative in four. We conclude that qualitative evaluation of two-dimensional echocardiographic images can identify changes in myocardial wall echogenicity that correlate with a result of gingival biopsy positive for amyloidosis. In patients who have a typical myocardial texture by two-dimensional echocardiography and a positive gingival biopsy result, cardiac amyloidosis should be strongly suspected.

In vivo and in vitro evaluation of left ventricular thrombi by two-dimensional echocardiography. Comparison with cineventriculography.

The purpose of this study was to assess the capability of two-dimensional echocardiography to identify left ventricular thrombi as compared to standard single plane cineventriculography in 284 patients, who underwent both procedures within 24 hours for diagnostic purposes. In order to obtain informations about the degree of thrombus organization and diagnostic accuracy of the echocardiographic technique, two-dimensional echocardiographic examinations were also performed in 31 thrombi from 16 autopsy specimens. In 249 cases the results were negative and in 14 cases positive by both techniques. Seven cases were positive by cineventriculography but negative by 2D-echocardiography. In seven cases the findings were equivocal by two-dimensional echocardiography; three of them were negative, two positive, and two equivocal by cineventriculography. In two cases the results were negative by two-dimensional echocardiography but equivocal by cineventriculography. Finally five cases were diagnosed to have a thrombus but two-dimensional echocardiography but not by cineventriculography. In two patients, positive by two-dimensional echocardiography, who were on anticoagulant therapy, follow-up studies showed the disappearance of left ventricular thrombi. In all of them the thrombi showed tissue characteristics similar to those of fresh thrombi examined in vitro. Two-dimensional echocardiography seems to be more reliable than cineventriculography for assessing the presence, extension, number, and morphology of left ventricular thrombi. In vitro studies suggest that two-dimensional echocardiography cannot visualize small thrombi, that fibrotic areas may simulate a thrombus and that in some cases under or overestimation is possible.

[Echocardiographic documentation of fibrocalcific degenerative changes of a lascia lata valvular prosthesis at the aortic valve].

The echocardiographic features of fibrocalcific degeneration of fascia lata aortic bioprosthesis are presented in two cases. M-Mode and 2D echocardiograms showed increased density and reduced motion of the bioprosthetic leaflets, suggestive of fibrocalcific degeneration. These features were confirmed at surgery. Two-dimensional echocardiography was mostly useful (in one case) in the assessment of morphology and motion of the diseased prosthetic valve.

Incidence of allergic rhinitis in children.

The authors give an account of the outcome of research done in the Allergo-Immunological Centre of the IInd ENT Division of Rome University, carried out among 210 children who were affected by nasal atopy. Particular stress was placed on the involvement of the nasopharyngo-tubal system. The age of the children ranged from 2-12 years and they underwent: 1) ENT visit; 2) allergy tests; 3) anterior rhinorheomanometry; 4) tubal function tests; 5) mucociliary clearance time; 6) X-ray examination of paranasal sinuses. The results revealed that the most frequent symptom in these children is rhinitis, whatever the allergic sensitization was. The forms of atopy which manifested themselves by chronical allergic patients (D.Pt. and P.O.) were the cause of: 1. asthmatic-type syndromes; 2. early onset of atopic symptoms around 4-7 years of age (9-10 years in the seasonal forms); 3. greater degree of extrinsic rhinitis with edema of the turbinates - the first step towards a polypoid degeneration of such subjects; 4. tubal functional deficit (60% of subjects allergic to P.O. and 50% allergic to D.Pt whereas only 27% are found in the seasonal forms); 5. mucociliary clearance linked directly with the length of disease; involvement of the paranasal sinuses (53/61 patients allergic to D.Pt., 9/28 allergic to P.O., 9/56 allergic to Graminacee). Furthermore the nasal patency was more insufficient in patients affected by the chronical forms of the atopy. In the light of these results the authors advocate focus attention on the significance of an early diagnosis of nasal atopy in children and the need for interdisciplinary collaboration among specialists.

Facial nerve function after cerebellopontine angle surgery and prognostic value of intraoperative facial nerve monitoring: a critical evaluation.

PURPOSE: Facial nerve monitoring is often used to predict postoperative facial function after acoustic neuroma tumor removal. In this study, three methods of predicting facial nerve function were compared. These methods used various parameters of the evoked electromyographic monitoring. MATERIALS AND METHODS: Thirty-four patients who underwent surgery for acoustic neuroma were retrospectively reviewed. Amplitude of ongoing electromyographic activity, stimulation current thresholds, and the amplitude of evoked response were analyzed. The predictive value of the three methods was compared with actual postoperative facial nerve function. RESULTS: One method predicted the final postoperative facial function in 90% of the patients, one method in 84%, and the final method failed to predict the final VIIth nerve function in patients with current stimulation thresholds greater than 0.05 mA. CONCLUSION: Analysis of prognostic value showed that one of the three studied proved superior in predicting facial nerve function.
