[Valve replacement with Macchi prosthesis].

OBJECTIVE: to evaluate the performance of a new ball valve prosthesis. DESIGN: set up of two groups of patients who underwent mitral valve replacement with two different prosthesis: the Macchi prosthesis under evaluation and the well known Starr-Edwards model prosthesis. The chi-square test was used to compare the results. PATIENTS: Patients referred for valvular surgery. INTERVENTIONS: One group of 98 consecutive patients who underwent isolated mitral valve replacement with a Macchi prosthesis from January 1984 to June 30 1986 was compared to a matched group of 49 patients who received a Starr-Edwards prosthesis in the same period of time. Follow-up data were available from 99% patients in the Macchi group 96% in the Starr-Edwards group, with a mean follow-up time of 35.2 (2-57) and 42.9 (4-62) months, respectively. RESULTS: There was no statistical difference in the incidence per 100 patients--month of prosthetic complications--thromboembolism, hemorrhagic events, prosthetic endocarditis, reoperation and mechanical failure. CONCLUSIONS: In our experience and with the available follow-up data the Macchi prosthesis is a good cost effective option when there is indication for a ball valve prosthesis.

[Pseudoaneurysm of the outflow chamber of the left ventricle as a complication of bacterial endocarditis of the aortic valve -- a clinical case].

After reporting a clinical case of a patient with a Staphylococcus Aureus Acute Endocarditis involving the aortic valve being complicated with cardiac failure irresponsive to medical treatment, which required a surgical procedure, the authors describe the preoperative echocardiography features. These features have the particularity of identifying a pseudoaneurysm rising in the outflow tract of the left ventricle, that involves the annulus and the anterior mitral leaflet, opening into the left atrium. They also take the opportunity to review the main local complications of Infective Endocarditis, affecting native or prosthetic valves, and make some comments on the diagnostic echocardiographic possibilities.

[Aorto-left ventricular tunnel arising from the left sinus of Valsalva].

Aortic-left ventricular tunnel (ALVT) is a rare congenital anomaly in which an abnormal communication connects the ascending aorta with the left ventricle, bypassing the aortic valve. Usually the ALVT takes its origin from the right aortic sinus. We report a patient with an ALVT arising from the left sinus of Valsalva who underwent surgery at five months of age. The diagnosis was first established by two-dimensional echocardiography.
