[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.

[Polygraphic indices of wearers of Hancock bioprostheses normally functioning in the aortic position].

A phonomecanocardiographic study in 33 patients who had undergone aortic valve replacement with a glutaraldehyde-preserved Hancock bioprosthesis, has been carried out 6 to 42 months after surgery. All xenografts were considered well functioning on the basis of clinical, electrocardiographic and radiographic evaluation. Typical phonocardiographic features of a well functioning porcine heterograft in aortic position were considered 1) an opening snap of variable intensity recorded in about 50% of the patients; 2) a normal closing sound; 3) a protosystolic ejection murmur which was always present and whose intensity was inversely related to the prosthesis size; and 4) the absence of a diastolic murmur. The anatomical and functional characteristics of the aortic valve of the pig are suggested to explain both the absence of a diastolic murmur and the pattern of the closing sound, which is undistinguishable from that of a normal aortic valve. Moreover, the reduced pliability of the right coronary cusp of the porcine valve, due to the muscular shelf at its base, with consequent limitation of the effective prosthetic orifice and relative stenosis of the device correlates well with both the opening snap and the sytolic ejection murmur.

[Phenocardiographic and auscultatory patterns in patients with normally functioning Björk-Shiley aortic prosthesis (author's transl)].

Phonocardiographic examination was carried out in 40 patients who had undergone to aortic valve replacement with the Björk-Shiley prothesis. The regular function of the prothesis was evaluated on the basis of the physical, radiological and electrocardiographic data. In the majority of the cases the first sound was slight. The prosthetic closing sound was made of two components (a2, A2) and the opening sound by one or more components (C1, C2, C3). A sistolic aortic murmur was always present, and a diastolic murmur has been found in 20% of the cases.

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.

[Left ventricular-right atrial communication. Diagnostic and therapeutic aspects: report of 16 cases (author's transl)].

16 cases of left ventricular-right atrial communication are reported. The most consistent clinical features, suggestive of this condition, were: auscultatory findings of V.S.D., electrocardiographic patterns of right atrial enlargement and biventricular hypertrophy, considerable right atrial enlargement coexisting with signs of left-sided cardiac enlargement and increased polmonary vascularity to Xray examination, echocardiographic fluttering of the tricuspid valve. Cardiac catheterization revealed an increased oxygen content in the right atrial or ventricular blood without the passage of the catheter through an A.S.D. The definitive diagnosis was established by left ventricular angiocardiography which demonstrated immediate opacification of a dilated right atrium through a septal defect; the location of the septal defect in the cardiac septum was attempted. In patients who suffered from a large left to right shunt were recommended for surgical treatment also in view of the relatively bad tolerance of this defect and low operative risk. There were two deaths: one baby died of early congestive failure. 9 cases were operated upon with one immediate postoperative death. The remaining, controlled by clinic follow-up, had good results.

Heart valve replacement with the Hancock bioprosthesis. Analysis of long-term results.

Between March 1970 and May 1976, 564 patients have undergone single or multiple heart valve replacement with the Hancock "SGP" bioprosthesis in our institution. Of these patients, 335 had single mitral, 102 aortic, one tricuspid, and 126 double or triple valve replacement, for a total of 629 xenografts. The long-term results, in terms of clinical improvement, survival, and complications, have been analyzed. Significant valve insufficiency secondary to primitive tissue alterations occurred in three patients, while reoperations were required in two for endocarditis and in two others for mitral stenosis caused by tissue ingrowth. We found that thromboembolic episodes occurred mainly in the early postoperative period up to the third month in 10 cases (1.76%). Three patients suffered peripheral embolization during the late follow-up period. Anticoagulants were not administered beyond 3 months postoperatively. Hemodynamic re-evaluation has been performed in 42 patients and the prosthesis has been shown to function properly either in the mitral or the aortic position. The data available to date indicate that the glutaraldehyde-preserved porcine valve is durable and we feel that its use is warranted in any valvular position.

[Phonocardiographic and auscultatory patterns in patients with normally functioning Lillehei-Kaster aortic prosthesis (author's transl)].

42 patients who had undergone aortic valve replacement with the Lillehei-Kaster prosthesis were studied. Phonocardiographic and physical examinations were carried out on these patients to determine the typical auscultatory pattern of this prosthesis. In the majority of the cases, the first sound was slight. The second sound was made up of two components, both produced by the artificial valve. A prosthetic opening sound was also detected. Moreover, a sistolic ejection murmur was present in all of the patients, and a diastolic murmur in 25%.

Giant blood cyst of tricuspid valve. Successful excision in an infant.

A case of a giant blood-filled cyst of the tricuspid valve in described in a 4-month-old infant. The cyst caused obstruction of the right ventricular inflow and outflow tracts and a right-to-left shunt; it was successfully removed at open heart surgery. Pitfalls in differential diagnosis and the pathogenesis are discussed.

[The congenital coronary artery fistula. Observations on seven cases (author's transl)].

The authors report seven cases of congenital coronary artery fistula observed in the Cardiology Department of Padua Medical School. The cardiopathy, the anatomo-histological characteristics, evolution and embriology are described. The anamnesic, clinical, electrocardiographic, X-Ray, phonocardiogram, haemodynamic, and contrastographic findings for each case are given. They are discussed and interpreted in the light of the pathophysiology of the disease.
