Abstract

Background: Complex left ventricular outflow tract obstruction (c- LVOTO) necessitates an diagnosis, follow – up and operation to void severe left ventricular outflow tract obstruction. There are some procedures, for example: Aor–ventriculoplasty (the Konno-Rastan procedure), apicoaortic conduit… However, all procedures require a prosthetic or allogeneic valve as well as postoperative anticoagulation therapy, reoperation, or both, the modified Konno procedure which avoid that problems.


Methods: This was a review of seri c-LVOTO  cases who underwent modified Konno procedure from 1/2014 to 12/2022. There were 8 patients ( 5 males and 3 females). The mean age was 5,6 years (range from 1 – 10 years) and the mean weight was 12,6  kilograms. The gradient of left ventricular outflow tract was 43 mmHg. All aortic valve were competents.


Results:  The time of cardiopulmonary bypass, aortic clamping were: 76 mins; 56 mins. There was no mortality.  The gradient postopration of LVOT and RVOT were 14 mmHg and 8 mmHg. During follow-up time 61 months after surgery, there was no late death. The gradient  of LVOT and RVOT were 10 mmHg and 6 mmHg


Conclusion: The modified Konno procedure had  good results with low gradient of  LVOT and RVOT
