[The experience with permanent cardiac pacing at the Surgical Clinic of the University of Padua Medical School (author's transl)].

A computer analysis is reported of the most significant data concerning 1624 pacemaker implantations and 1386 battery replacements. The patients were treated by endocardial stimulation with transvenous electrodes in 91% of the cases; the remainder: 9% received epicardial electrodes. The mode of stimulation was 2189 times "demand", 138 "synchronized" and 683 "asyncronous". Pacers of 13 different brands were used. At the beginning of our experience, the catheter was introduced through the superficial or profunda giugular vein: since 1969 the cephalic vein has been preferred. Epicardial electrodes were implanted via a left thoracotomy but in the most recent years the extrapleural phrenico-pericardial approach has been adopted. In a number of cases external pacemakers have been employed for permanent stimulation. The most common post-operative complications were infection (3.9%), skin erosion (2.2%), catheter rupture (3.5%), electrode dislodgement (1.7%). Such complications are becoming less frequent since 1969, due to technical improvements.

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.

[Rupture of the posterior wall of the left ventricule after replacement of the mitral valve: a description of 8 cases (author's transl)].

Eight cases of left ventricular rupture at the atrio-ventricular groove among 693 mitral valve replacements, isolated or associated with other surgical procedures, are reported. In the authors' opinion, the surgical technique of the mitral valve's removal, especially if calcific or with subvalvular disease, as well as the method and the site of implantation of the prosthesis, are the main factors in determining this severe complication. In order to avoid the rupture of the posterior wall of the left ventricle, a simple modification of the surgical technique which reinforces the valvular annulus is suggested.

Anatomical study of truncus arteriousus communis with embryological and surgical considerations.

Twelve specimens of truncus arteriosus communis have been studied anatomically, with special reference to the conal anatomy and to the associated cardiac anomalies which can create additional problems if surgical repair is planned. A wide spectrum of conal morphology has been observed, suggesting that differential conal absorption is a developmental characteristic of truncus arteriousus as well as of transposition complexes. The invariable absence of septation of the ventricular infundibula and semilunar valves, in spite of the variable anatomy of the free wall of the conus, indicates that all types of truncus arteriosus, ontogenetically, should be considered as a single undivided conotruncus. Various types of ventircular septal defect were found: (a) ventricular septal defect with absent crista, in which no remnants of conal septum are present; (b) supracristal ventricular septal defect, in which vestigial conal septum is seen in front of the membranous septum; (c) bulloventricular foramen, associated with univentricular origin of the truncus from the right ventricle. Frequent associated anomalies are underdevelopment of the aortic arch, truncal valve malformations, and obstructive ventricular septal defect. The AV conduction system studied in one case showed an arrangement similar to Fallot's tetralogy with the His bundle and the left bundle-branch in a safe position behind the posteroinferior rim of the defect. The postoperative fate of the frequently abnormal truncal valve and the theoretical indications for total repair for Type IV truncus are also discussed.

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.

[Infections in pacemaker carriers (author's transl)].

Of 2243 cardiac pacemakers implanted at the cardio-surgical centre of the surgical clinic in the University of Padua, 150 cases of infection were observed, mostly caused by a delayed cutaneous decubitus from the electrode or the battery. The main causes for infection in pacemaker carriers and the most suitable means for their prevention are discussed.

[Anatomically corrected malposition of the great arteries (author's transl)].

Anatomically corrected malposition of the great arteries is defined as a trunco-conal malformation characterized by an aorta arising anteriorly from a morphologically left ventricle and by the presence of a subaortic muscular conus. This malalignment determines a conotruncal-ventricular discordance: d-loop and l-position or l-loop and d-position of the aorta. Two additional cases of this very rate lesion are reported, both associated with left juxtaposition of the atrial appendages, tricuspid atresia, ventricular malrotation and destrocardia in situs solitus with d-loop. Because of the high frequency of this association, observed also in the majority of the previously published cases, its morphogenetic significance and implications are discussed.

[Postoperative bacterial endocarditis after cardiac prosthesis (author's transl)].

The infection of an endocardial prosthesis, either valvular or septal patch, is a frequent and dangerous post-operative complication. Eleven patients having postoperative endocarditis (9 on valve prosthesis and 2 on ventricular septal patch) are the subject of this paper. Six of the 7 infected "early" had Gram-negative bacteria in the blood cultures, while staphylococus aureus, streptococcus viridans and klebsiella pneumoniae were responsible for 3 of the 4 "late" infections. In 2 patients, one "early" and one "late" the causative bacteria were not identified. The definite prevalence of Gram-negative flora in post-operative endocarditis may have been facilitated by the routine use of antibiotics after open-heart surgery. Three of the 11 patients survived, one after replacement of the infected prosthesis and two after prolonged specific antibiotic treatment. On the basic of this experience, compared with other written reports, the authors propose to treat postoperative endocarditis medically for approximately 5 weeks, with full doses of specific antibiotics, reserving for surgical treatment only the cases of prosthetic malfunction, left atrial thrombosis, peripheral embolization and in those patients where the medical treatment fails.
