Background: It is unknown whether progression of familial idiopathic dilated cardiomyopathy differs from progression in the non-familial form. It has been suggested that familial disease indicates a worse prognosis, and that this should be considered when planning the timing of heart transplantation. Objective: To compare five year survival or time to heart transplantation in an unselected series of patients with dilated cardiomyopathy who had been evaluated for familial v non-familial disease t...

We reviewed medical records from eight patients (4 to 29 years of age) with a functional single ventricle and pulmonary microthrombosis as observed on open lung biopsy specimens. Hemodynamic assessment before biopsy revealed pulmonary hypertension (mean pulmonary artery pressure 19 to 53 mm Hg) in the seven patients tested and severely increased pulmonary arteriolar resistance (6 to 13 U-m 2 ) in three of the five patients in whom these measurements were performed. Pulmonary blood flow varied (<...
