Abstract
The patient was diagnosed with perimembranous ventricular septal defect (VSD). She underwent VSD closure and muscle bundle resection across right ventricular outflow tract at the age of 3 months. Since then, she had suffered from severe heart failure and complete heart block. Permanent pacemaker generator was implanted in the left hypochondrium. She was depended on continuous catecholamine administration, so transferred to our hospital for further management. On arrival, her body weight was 5686 g (- 2.7 SD). She underwent Excor pediatric left ventricular assist device implantation at the age of 9 months. Because the position of the left ventricular assist device cannula interfered with the pacemaker, herein, the pacemaker pocket was newly created in the left thoracic cavity. An 1 mm in thickness of expanded polytetrafluoroethylene sheet was trimmed and sutured under the anterolateral wall of left thoracic cavity as a pacemaker pocket. Bipolar ventricular lead was sutured on left ventricular apex and basal wall to face each other, mimicking cardiac regeneration therapy. Even though she unfortunately required right diaphragmatic plication for iatrogenic phrenic nerve palsy, her respiratory function was well maintained; therefore, secondary right heart failure was not observed. Her cardiopulmonary function was quite stable until post-operative day 275 when the patient was transferred to another hospital for heart transplantation.
