[Echo-angiocardiographic correlations in congenital abnormalities of the mitral valve (author's transl)].

Echocardiographic findings satisfactorily compared with angiocardiographic data in six infants affected by congenital abnormalities of the mitral valve. Peculiar echocardiographic features were as follows: a) mitral stenosis: reduced E-F slope of the anterior mitral leaflet, paradoxical diastolic movement of the posterior leaflet, enlargement of the left atrium; b) "parachute mitral valve": small, dysmorphic, stiff mitral valve, with an extra echo projecting between those of the two leaflets; c) "cor triatriatum": enlarged left atrium whose cavity is divided in two portions by an extra echo; d) "hypoplastic left heart syndrome": the mitral leaflets are thin, short. The ventricular cavity and the diameter of the aorta are small; the right ventricle and the pulmonary artery are on the contrary markedly dilated.

[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.

[The mitral prolapse syndrome. Observation of 100 cases (author's transl)].

100 patients with mitral prolapse syndrome (MPS) were studied with electrocardiogram, phonocardiogram, thorax radiography and echocardiogram. In 44 of the patients, the effort test and dynamic electrocardiogram were performed; 25 underwent hemodynamic examination, and 10 underwent selective coronarography. The most frequent symptomatologies were palpitations and vertigo; the most-registered electrocardiographic alterations were ventricular extrasystoles and altered electrical repolarization in the inferior seat. The symptomatic patients with rhythm disturbances showed reduced work capacity (RWC) with aggravation of the effort arrhythmias. The phonocardiogram showed variability of the phonoauscultatory reports, not only from patient to patient, but also in the same patient. The apicocardiogram presented a characteristic systolic re-entry which coincided with the non-ejective click. In all cases, the echocardiogram demonstrated a systolic movement backwards from the mitralic strips with different aspects. The endocavitary pressures in the studied cases were normal or only slightly altered. The left ventriculography frequently demonstrated assynergic areas, and constantly, eversion of the posterior mitralic strips in the left atrium. In most of the cases, the selective coronarography showed the absence of the ventricular atrial tract of the circumflex. The sustained role of the mixomatous degeneration in the pathogenetic mechanism of the MPS must be emphasized. The beta-blockers were the most effective drugs against arrhythmias, which in some cases showed themselves impervious to any medicinal treatment. MPS is considered a very diffuse disease which can run its course without detection or which can be accompanied by serious rhythm disturbances that can threaten the patient's life. The importance of echocardiography in the diagnosis of MPS is emphasized. The SPM patient showed undergo a series of wave tests which reveal malignant potentialities, so that the best therapeutic principles, both for the treatment and prevention of the arrhythmias, can be applied.

[Use of atrial pacing in diagnosis of coronary insufficiency. Comparison between coronarography and exercise test (author's transl)].

--123 atrial pacings (AP) performed as diagnostic investigations in patients with chest pains were re-examined. By using floating catheter without fluoroscopic control, this technique is very simple to perform and free from relevant risks. The diagnostic sensibility and specificity of AP were examined in 93 patients in which a coronary arteriography was performed; these figures were compared with the corresponding values observed in 65 patients in which an adequate diagnostic exercise test (ET) was also available. The diagnostic sensibility of AP examined in 63 patients with significant coronary artery disease was 90%; the corresponding value of ET was 79%. In particular, in patients with single vessel disease, the sensibility of AP (90%) was much higher than that observed in ET (40%). The specificity of AP examined in 30 patients free from significant stenosis of the coronary arterial tree was 43%. This value was largely lower than that observed in ET (82%) in the same patients, and appears to be inadequate for validation AP as a diagnostic tool in coronary heart disease. Therefore, AP must be limited to functional, and not diagnostic, evaluation of patients in which the diagnosis of coronary heart disease can be made by other means.

[Unstable angina: observtions on 187 patients of whom 84 were operated on for aorto-coronary bypass (author's transl)].

Clinical data, EKG and coronary angiography of 187 patients with unstable angina are given. The patients are divided into 4 groups: spontancous angina, spontaneous angina Prinzmetal's variant, "in crescendo" agina, intermediate syndrome. 103 patients were treated with pharmacological therapy only and 84 underwent aortocoronary bypass; 2 of them were operated on for acute myocardial infarction. The clinical and pathologic peculiarities of two groups are not similar and therefore the results are not comparable. There was a mortality rate of 10.3% of patients with pharmacological treatment and the incidence of non fatal myocardial infarction was 10.4%. The mortality during operation was 14.2% and the incidence of non fatal myocardial infarction was 13.1%. The spontaneous angina and Prinzmetal's variant often had normal rest EKG and a very similar coronary angiographic pattern, with obstructive lesions often localized in the proximal part of a single vessel. In 9% of cases coronary arteries were normal. The incidence of serious arrhythmias was higher in Prinzmetal's variant than in other types of unstable angina. The mortality in patients with Prinzmetal's angina was particularly high during the first period of experience (1970-1973) when the operation was performed after a few days of unsatisfactory results with pharmacological treatment; it decreased after patients underwent operation in an attenuate phase of the disease. The rest EKG of "in crescendo" angina was almost always pathologic; these cases presented obstructive lesions of 2 or 3 coronary arteries, functional impairment of left ventricle, collateral circulation. The mortality in patients treated with pharmacological therapy was higher than in other types of unstable angina. The mortality during operation, fairly high in the first period of experience, decreased in this group of patients as well, during the second period of experience.

Reporting, filing, and retrieval of coronary angiographic findings: a new personal computer-based system.

A software system for semiautomatic reporting and automatic filing of coronary angiographies has been developed and is suitable for an IBM Personal Computer (PC) with graphic tablet and printer. Coronary angiographic findings referring to the native anatomy, pathology, and post-surgical status can be easily recorded. The data is automatically coded and filed according to category of information. This system can analyze previously filed data and perform searches under one or more angiographic findings. This allows for a comparison of different series of patients.

CT demonstration of liquid intratumoral fat layering in a necrotic renal cell carcinoma.

We describe a case of clear-cell adenocarcinoma of the kidney with CT evidence of fat that contradicts the rule that radiologically demonstrable fat is absent in renal carcinoma. The cyst-like appearance, egg-shell parietal calcifications, and extrarenal development of the mass suggested a preoperatively incorrect diagnosis of teratoma.

Sonography after renal biopsy: assessment of its role in 230 consecutive cases.

Among 230 patients undergoing ultrasound (US) guided renal biopsy, 218 had postbiopsy sonography. Clinical records were reviewed to correlate symptoms to US findings. In each case of large hematoma (thickness above 1 cm), all postbiopsy sonographic studies were analyzed to look for findings indicative of unfavorable outcome. A total of 96 subcapsular/perirenal hematomas were found. Large hematomas were observed in 20 patients (20/230 = 8.7%), seven of these (3%) were severely symptomatic. In the absence of clinical signs of bleeding, no patient had clinical consequences. In the presence of clinical signs of bleeding, serious complications occurred only in patients with large hematomas. US thickness of retroperitoneal hematoma correlated to clinical outcome: whenever measured thickness was less than 2 cm, clinical evolution was very favorable, whereas a thickness above 2 cm was invariably associated to clinical signs of bleeding. In six of seven cases of thickness exceeding 3 cm, severe complications developed. An unfavorable evolution was associated with increasing thickness and an echogenicity inappropriate with respect to the time elapsed since biopsy. Hydroureteronephrosis, peritoneal effusion, and anomalous vascular images were indicators of deterioration. We conclude that sonography is indicated only for symptomatic patients and that the monitoring of both thickness and changing echogenicity of retroperitoneal blood collections supplements clinical follow-up.

[Cardiac fibroma: a successfully operated case and a review of the literature (author's transl)].

A case of cardiac fibroma in a three years old child successfully operated on is presented. The tumor was localized on the interventricular septum and was provoking an obstacle in the outflow of the right ventricle. The preoperative diagnosis was formulated by angiocardiography. A year after the operation, the hemodynamic control showed that he interventricular pressures were normal. The problems and the importance of an early diagnosis are emphasized in patients affected by cardiac fibroma. Surgical indication, technical aspects related to the operation, the immediate and more long-term results from surgical operation of this kind of pathology, with reference to the data taken from the literature, are discussed.
