tient      to be positive             for the HLA-B27                        antigen.         Serologic

preparation          and antinuclear             antibody.
    An M mode echocardiogram                              (Fig         1) revealed            a dilated
aortic root which on various views measured between 5 and 6
cm. There          was a persistent             additional           echo line parallel               with
and posterior           to the anterior             aortic wall, separated                   from that
wall by 1.5 cm. Most views showed                                 the space between                  these
parallel      lines to be echofree,                 although          with minimal             attenua-
tion some reflections                could be recorded                    from that area. The
aortic valve leaflet echoes                   were always               identified        behind       and
separate        from the two anterior                    aortic       echoes.       These       findings
were felt to be compatible                      with an anterior                 dissection         cham-
ber and a posterior              true lumen. Other features                         of the M mode
echo included              a normal         diameter           left atrium,            a dilated        left
ventricle        (diastole       6.8 cm) and a mitral                     valve demonstrating
 diastolic      fine flutter        and marked              premature             diastolic       closure
 consistent        with aortic         regurgitation             “A” waves             were seen on
 the mitral         echo       only during             the short            R-R       cycles       of the
Wenckebach              rhythm.
    Confirmation         of aortic dissection           was sought           by performing
a two dimensional             real-time     ultrasound         study       (Fig 2) using a
commercially          available       mechanical         sector      scanner.       Again     the
aorta appeared           as a dilated       “double        lumen”        structure       with a
persistent     bright      linear echo 1.5 cm behind                  the anterior        aortic
wall with fixed relationship                to that wall in systole.                Behind it,
fragments        of normally          moving       aortic leaflet tissue were re-
corded.     Long and short axis views were complimentary,                                    and
                                                                                                               Ficuna       3. Aortogram          in left anterior       oblique     position.        The
