[Echo-Doppler study of myxomatous mitral valve insufficiency and the results of reparative surgery].

The aim of conservative management of mitral regurgitation caused by floppy mitral valve is to restore a valvular function which closely resembles that of normal physiology. Fifty-eight patients affected by floppy mitral valve underwent surgical procedures for severe mitral regurgitation due to chordal elongation and/or rupture. Of these, 28 presented posterior mitral prolapse corrected by quadrangular excision of the prolapsed part and posterior anuloplasty achieved by apposition of a polytetrafluoroethylene conduit.

Quantitative regional contraction analysis of cineventriculography: reporting, filing, and retrieval functions using a personal computer.

A new method for the semiobjective evaluation of left ventricular wall contraction is proposed that uses a percent reduction of areas. The calculation model uses orthogonal coordinates, an internal reference system, and the concept of nonuniform reduction of the cavity, with its obliteration at the apex. From a normal patient population (ten males, four females; aged 45 +/- 13 years), a "normal reference curve" of contraction was obtained.

[Proposal of a standardized graphic system for collecting coronary angiographic data. Processing with a personal computer].

A standardized method for the representation and filing of coronary angiographies is proposed. Semi-automatic reference is guided by a computer algorithm. The final report displays a diagram which shows all the information in graphic and alpha-numeric form.
