new-onset atrioventricular block.

The major morbidity after
the Konno AVP is complete heart block. The incidence of
pacemaker insertion following the Konno procedure has been
reported to be from 6 to 12.5%.

Another problem that may be encountered is dehiscence of
the patch from the interventricular septum with communication
between the left and right ventricles. This problem may require
re-operation for correction of the ventricular septal defect. In
addition, it is important to prevent damage to the first septal
branch of the left anterior descending coronary artery.

There
were no complications observed in our case.
Conclusion
Konno aortoventriculoplasty can be safely used in repeat AVR
in adults, even if the patient has previously undergone a double
valve replacement. This can be achieved with low operative
mortality and good long-term outcome.
