Suicide right ventricle after lung transplantation for pulmonary vascular disease.

A 27-year-old female with Eisenmenger's syndrome underwent closure of a patent ductus arteriosus, closure of a perimembranous ventricular septal defect and mid muscular defect and bilateral lung transplantation. Her immediate postoperative course was complicated by severe right ventricular outflow tract (RVOT) obstruction resulting in hemodynamic collapse, a condition described as suicide right ventricle. The patient was placed on central Veno-Arterial Extra-Corporeal Membrane Oxygenation as a bridge to the relief of RVOT obstruction which included a right ventricular outflow muscle resection and a right ventricle outflow tract patch. The patient made an uneventful recovery.

Validation of a quality of life questionnaire in the Pacific Island.

PURPOSE: To adapt an existing validated quality of life instrument, the Impact of Vision Impairment (IVI) questionnaire for Pacific Island countries. METHODS: Following in-depth interviews (n = 24) and a pilot study (n = 67), the original 32-item IVI questionnaire was translated and adapted in Vanuatu. The Melanesian IVI (IVI_M) was administered to participants not previously involved in the pilot study (n = 189). RESULTS: Participants included 117 (62%) with mild, moderate or severe vision impairment, 39 with unilateral loss and 33 with normal vision. Eighty-six percent of the original 32-items were deemed relevant by 90% of participants. Items displaying floor effects were removed (4), 2 were combined and 3 items rephrased to reflect Melanesian-specific activities, resulting in a 23-item IVI_M. Nineteen items were relevant to both the Melanesian and Australian contexts including all 8 items related to the emotional reaction to vision loss. IVI_M demonstrated content and construct validity, reliability and discriminated visually healthy populations from those with vision impairment. Vision impairment of < 6/18 negatively effected quality of life. CONCLUSION: While the adaptation process demonstrated the need for culturally relevant instruments, it also highlighted the value of adapting existing validated instrument for use in cross-cultural research rather than developing a new instrument from first principles.
