benefit from early screening and preventive measures.
These measures could include lifestyle interventions
such as improving diet and physical activity as well as
increased surveillance of blood pressure, serum lipids,
and particularly blood glucose.

Background: Longer survival after the total
repair of the Tetralogy of Fallot increases
the importance of late complications such as right
ventricular dysfunction. This is a prospective study
of the right ventricular function in totally corrected
Tetralogy of Fallot patients versus healthy children.
Conclusion: RVMPI was significantly correlated
with PR severity without the presence of a significant
correlation between RVMPI (obtained by pulsed wave
Doppler) and the RV function indices obtained by tissue
Doppler imaging (EA, Aa, Ea/Aa, and Sa). We suggest
that these indices, RVMPI by tissue Doppler and PRi,
be measured basically at postoperative and follow-up
evaluations. In addition, as TAPSE was significantly
decreased in the totally corrected TOF patients and
there was a significant correlation between TAPSE and
Sa, we suggest that TAPSE be also measured as the
global RV systolic function index.

Background: Isolated right bundle branch block
(RBBB) is a common finding in the general
population. The atrioventricular node (AVN) artery
contributes to the blood supply of the right bundle
branch. Our hypothesis was that the anatomy of
the AVN artery and the pattern of dominancy differ
between subjects with and without RBBB.
Conclusion: According to our observations, there
was no relationship between the dominancy of the
epicardial arteries and the presence of RBBB in
subjects with normal coronary arteries. There was
a great variation of the AVN artery origin. Non-crux
origination of the AVN artery was more common than
the crux origination in both groups, and the prevalence
of non-crux origination of the AVN artery was
significantly higher in the cases than in the controls.
Origination of the AVN artery from the right circulatory
system was more common in both groups and the
prevalence of the right origin of the AVN artery was
significantly higher in the cases than in the controls.
The AVN artery most commonly originated from the
dominant artery but not necessarily from the crux.
