[A new ventilation method: the laryngeal mask].

A size 3 laryngeal mask was used in 20 patients who underwent elective general surgery. It consists of a silicon tube attached to mask which must be inserted into the hypopharynx and then inflated. No curarisation nor laryngoscopy is needed. Operations were performed in assisted or spontaneous ventilation, with good airway patency and absence of coughing, secretions and sore throat. In 2 cases introduction of the mask failed. Technique, advantages and problems related to its use are described.

Alterations of the endoalveolar surfactant after surgery with extracorporeal circulation.

In 10 patients who required extracorporeal circulation (ECC) during surgery, we studied the damage induced by surgery to the pulmonary surfactant and the effectiveness of ambroxol in preventing changes in the phospholipid pool. There were 5 control patients and 5 patients who were given 1 g/day of ambroxol on the 4 days prior to and the 4 days after surgery. To follow changes in phospholipid concentrations, bronchoalveolar lavage (BAL) was performed before surgery and 24 h and 8 days after ECC. Phospholipids were assayed in the BAL liquid by two-dimensional thin-layer chromatography. There were marked decreases in total phosphorus and quantitative alterations of individual phospholipid species in the surfactant of the control group, but not in the patients treated with ambroxol.

[Prosthetic valve endocarditis].

The Authors report their experience of the surgical treatment of cardiac prosthetic endocarditis. Between September 1974 and December 1988, 2,796 cardiac prostheses were implanted. An endocarditis in the follow-up of 23 patients involving 27 prostheses was diagnosed. The operative mortality was high in patients with mitral prosthetic endocarditis; in patients with infected aortic prosthesis operative mortality was low, but there was a high incidence of recurrence. The Authors emphasize the difficulty of diagnosis and the importance of the surgical treatment for eradication of the infection and for resolution of the haemodynamic defect.

[Intermediate echocardiographic follow-up of a new model of pericardial prosthesis (Pericarbon)].

The paper deals with the echocardiographic medium-term follow-up of 11 patients fitted with a Sorin Pericarbon bioprosthesis. Four hundred and ninety-seven biological prostheses were implanted during the period January 1975 to December 1988, of which 22 (4.42%) were Pericarbon. The first 11 patients (mean age 55.3 years) who underwent isolated mitral or aortic valve replacement were included in the study. In 5 patients the bioprosthesis was implanted in mitral site, and in 6 in aortic. Post-operative 2D-Doppler echocardiographic tests revealed good hemodynamic performance indices, even in small calibre vessels, and the absence of early malfunctions. Although the number of patients studied is small, the absence of early malfunctions and the technical innovations of the bioprosthesis make it preferable to other pericardiac prostheses.

Clinical results after cardiac valve replacement with the Sorin prosthesis. A 6-year experience.

The mechanical valve produced by Sorin is a modified tilting disc device. Between March 1979 and November 1985, 763 Sorin prostheses were implanted in 710 patients. The study has been restricted to 504 isolated mitral or aortic valves. There were 238 females and 266 males whose ages ranged from 2 to 71 years (mean 43.8). Follow-up is 99.23% and covers 1045 patient-years. No structural failure has been observed. In the aortic position, 282 Sorin prostheses were implanted with the large orifice orientated towards the right coronary sinus. Hospital mortality was 5% (14/282). Actuarial survival at 78 months was 94.68% +/- 1.6% with a linearized mortality rate of 1.7% patient-years. There were 11 late deaths (9 valve-related and 2 non valve-related). The linearized rate of occurrence of embolic events was 0.32 patient-years (2/268). Actuarial survival complication-free at 78 months was 90.88% +/- 2.83%. Preoperatively, 19.8% patients were in NYHA class II, 68.5% in III and 11.7% in IV; postoperatively, 79.3% patients were in NYHA class I, 19.5% in II and 1.2% in III. In the mitral position, 222 Sorin prostheses were implanted with the large orifice orientated anteriorly in 46 patients (group 1) and posteriorly-in 176 patients (group 2). Hospital mortality was 4.5% (10/222). Actuarial survival at 66 months was 93.25% +/- 2.1% with a linearized mortality rate of 2.8 patient-years. There were 12 late deaths (9 valve-related and 3 non valve-related). The 66-month actuarial freedom from embolic events was 95.8% +/- 1.89% with a linearized rate of occurrence of 1.44 patient-years.(ABSTRACT TRUNCATED AT 250 WORDS)

Cardiac valve replacement during pregnancy. Report of two cases.

Two successful cases of mitral valve replacement with cardiopulmonary by-pass and myocardial protection are reported. Postoperative anticoagulation was obtained with oral anticoagulants. The patients delivered two healthy newborns. The report suggests that an open-heart operation can be performed in pregnant women with an acceptable risk for the mother and the fetus.

Clinical results after isolated aortic valve replacement with Sorin prosthesis: a 6-year experience.

The mechanical valve produced by Sorin is a modified tilting disc device. Over about a 6-year period, 763 Sorin Prostheses were implanted in 710 patients. No structural failure has been observed. 282 prostheses were implanted in aortic position with the large orifice oriented towards the right coronary sinus. Hospital mortality was 5% (14/282). Actuarial survival at 78 months was 94.68% +/- 1.6%, with a linearized mortality rate of 1.7% pt-years. There were 11 late deaths (9 valve related and 2 non valve-related). The linearized rate of occurrence of embolic events was 0.32 pt-years (2/268). Actuarial survival complication free at 78 months was 90.88% +/- 2.83%. Preop. 19.8% patients were in class II N.Y.H.A, 68.5% in III, 11.7% in IV; postop. 79.3% patients were in class I, 19.5% in II, 1.2% in III. The durability and satisfactory complication-free survival rate indicate the Sorin prosthesis as a fully reliable device for aortic valve replacement.

Right intracavitary cardiac tumors. Surgical management.

The surgical treatment of 6 patients affected by right cardiac tumors is reported. Three of them showed a right atrial myxoma, 1 metastases from an occult embryonal carcinoma and 1 a leiomyosarcoma of the pulmonary artery. While clinical diagnosis was not reliable, the echocardiographic examination was able to assess the site of the tumor, supplying useful information for the anatomy and surgery in 5 cases out of 6; in one case, the diagnosis was reached intraoperatively. All the patients survived the surgical treatment: while those with atrial myxoma recovered completely, the others with malignant tumors died from metastases 5 to 10 months postoperatively. The importance of early diagnosis is stressed together with the role of surgery, which permits the recovery of cases with benign tumors and a longer survival of cases with malignant tumors.

A clinical and hemodynamic study of a case of polysplenia, with typical left bilateral symmetry, anomalies of systemic venous drainage and defect of the endocardial cushions. A brief revision of the literature is given and the embriological and clinical concept of the left bilateral symmetry is discussed.
