Abstract
INTRODUCTION AND IMPORTANCE: Left ventricular outflow tract obstruction (LVOTO) is a rare complication after surgery for Ebstein's anomaly. Early detection of this complication is crucial. CASE REPORT: We report a case of an elderly woman with Ebstein's anomaly who developed LVOTO after cone reconstruction. She was discovered in time and underwent tricuspid valve replacement, saving her life. CLINICAL DISCUSSION: This rare complication of cone-plasty has taught us lessons. Early diagnosis and clinical monitoring of ultrasound during the clinical process and reduction of multiple injuries during surgery can reduce the chance of accidents. CONCLUSION: LVOTO after conical surgery for Ebstein's malformation is rare and fatal and needs to be detected and corrected promptly.
