  • Look Inside

Right ventricular volume characteristics and function were studied in 13 patients with single right ventricle (SV), in 14 with tetralogy ofFallot (TF), 7 with camplete transposition of the great arteries (TGA) and 6 with Eisenmenger syndrome (Eis). Right ventricular end-diastolic volume index ranged from 72 to 282 (132+16.0)ml/m2 in SV, 31 to 75 (55±3.4) ml/m2 in TF, 61 to 130 (92±10.8) ml/m2 in TGA and 50 to 143 (88±13.0) ml/m2 in Eis, respectively. These values in TF, in TGA and in Eis were equal to 96±16.0, 200±23.4 and 106±5.4% of the normal right ventricular end-diastolis volume, respective-ly. End-diastolic volume of SV was equal to 112 +10.7% of the sum of the normal left and right ventricular end-diastolic volumes. In SV, pulmo-nary blood flow affected for the ventricular volume. There was a high correlation coefficient (γ=+0.90) p<0.001) of pulmonary to systemic flow ratio (Qp/Qs) with end-diastolic volume index (EDVI). But, there was no correlation between Qp/Qs and EDVI in TF, TGA and Eis.

Ejection fraction (EF) averaged 0.54±0.023, 0.53±0.014, 0.47±0.088 and 0.49±0.044 in SV, TF, TGA and Eis, respectively. In SV, EF (0.49±0.034) in patients with atrioventricular regurgi-tation was significantly (p<0.05) lower than that (0.60±0.016) in patients without atrioventricular regurgitation.
