The aim of the study was to evaluate segmental and global right ventricular function at rest and during stress in patients having a systemic morphologically right ventricle. We studied 17 patients after atrial correction for transposition, 13 with congenitally corrected transposition, and 11 age-matched controls using cardiovascular magnetic resonance at rest and during stress with dobutamine given at 15 micrograms per kilogram per minute. Blood was drawn to obtain levels of brain natriuretic peptide. Right ventricular ejection fraction was calculated, and wall-motion and wall-thickening were assessed, in 4 segments of a midventricular slice. The findings for the systemic right ventricle were compared to the left ventricle in controls. Patients with transposition showed a decreased ejection fraction at rest (57 percent versus 69 percent, p equal to 0.005), decreased wall motion of the anterior, lateral and septal wall (p less than 0.01, p less than 0.01, and p less than 0.01) and decreased thickening of the lateral wall (p less than 0.01). Patients with congenitally corrected transposition showed normal ejection fraction, wall thickening, and wall motion at rest. During dobutamine stress, we found no significant differences in wall motion and thickening between the two groups. Ejection fraction, also increased to comparable values during stress, at 67 percent versus 66 percent, p not being significant. In both groups, we observed similarly increased levels of brain natriuretic peptide (p equal to 0.02 and 0.03, respectively). We conclude that only patients with transposition showed segmental wall motion and wall thickening abnormalities at rest. After dobutamine stress, however, segmental and global right ventricular dysfunction was similar in both groups.

Patients with congenitally corrected transposition are at risk of right ventricular dysfunction and failure. With this in mind, we examined 13 patients with congenitally corrected transposition, 7 not having undergone surgery, and 6 after physiological repair, comparing them with 6 healthy subjects matched for age and sex, using cardiac magnetic resonance imaging, at rest and during dobutamine stress, in order to determine regional and global right ventricular response to stress.At rest, the patients had significantly decreased overall wall motion compared to their healthy peers (7.2 ± 0.5, versus 9.8 ± 0.4 mm). During infusion of dobutamine, overall wall motion increased to 12.8 ± 0.4 mm in the healthy subjects, versus 8.8 ± 1.0 mm in patients. At the regional level, significant differences in mural motion were found between patients and controls in the anterior (9.5 ± 1.1, versus 13.2 ± 0.6 mm), posterior (10.2 ± 1.6, versus 13.2 ± 0.8 mm), and septal segments (5.0 ± 0.8, versus 11.2 ± 0.6 mm).At rest, overall mural thickening in patients was similar to that of controls, but significantly less in patients during stress. During dobutamine stress, patients showed significantly less regional wall thickening than controls, particularly in the septal (2.7 ± 0.6, versus 6.0 ± 0.4 mm, respectively) and in the anterior segments (4.2 ± 0.6, versus 7.8 ± 0.6 mm, respectively). Right ventricular ejection fraction strongly correlated with mural motion and thickening, both at rest and during stress.Abnormal regional function in the systemic morphologically right ventricle may occur in patients with congenitally corrected transposition, which strongly correlates with right ventricular ejection fraction. Our findings support the hypothesis that, in patients with congenitally corrected transposition, ischemia of the right ventricular myocardium contributes to the development of right ventricular dysfunction.

AbstractBackgroundPatients with a congenitally corrected transposition of the great arteries show an increasing incidence of cardiac failure with age. In other systemic right ventricles, such as in dextro-transposition after atrial switch, excessive hypertrophy is a potential risk factor for impaired systolic function. In this trial, we sought to compare systemic function and volumes between patients with congenitally corrected transposition and those with dextro-transposition after atrial switch by using cardiac magnetic resonance imaging.Methods and ResultsA total of 19 patients (nine male) with congenitally corrected transposition and 31 patients (21 male) with dextro-transposition after atrial switch were studied using a 1.5-Tesla scanner. Cine steady-state free-precession sequences in standard orientations were acquired for volumetric and functional imaging. Patient parameters were compared with those of a group of 25 healthy volunteers. Although patients with congenitally corrected transposition were older, they presented with higher right ventricular ejection fractions (p = 0.04) compared with patients with dextro-transposition. Patients with congenitally corrected transposition showed a weak negative correlation between age at examination and systemic ejection fraction (r = −0.18, p = 0.04) but no correlation between right ventricular myocardial mass index and ejection fraction. There was no significant difference in the right ventricular end-diastolic volumes between both patient groups.ConclusionAlthough patients with congenitally corrected transposition had a longer pressure load of the systemic right ventricle, ventricular function was better compared with that in patients with dextro-transposition after atrial switch. The results suggest that the systemic ventricles might have partly different physiologies. One difference could be the post-operative situation after atrial switch, which results in impaired atrial contribution to ventricular filling.

AbstractSystemic right ventricular function in congenitally corrected transposition depends on septal geometry. Suprasystemic left ventricular systolic pressures and high end-diastolic pressures after Fontan surgery paradoxically preserve right ventricular function.

AbstractObjectivesTo assess neurohormonal activation of cardiac failure in adults with congenitally corrected transposition, and to determine the most sensitive marker for recognition of the cardiac failure.BackgroundThe onset of morphologically right ventricular dysfunction is unpredictable in patients with congenitally corrected transposition, the combination of discordant atrioventricular and ventriculo-arterial connections, and its markers are unknown.MethodsWe measured amino terminal pro brain natriuretic peptide in 19 patients, aged 35 plus or minus 13.1 years, and in 19 control subjects. Morhologically right ventricular function was assessed by echocardiography, including tissue Doppler echocardiography and magnetic resonance imaging or multislice computed tomography.ResultsThe patients showed a highly significant increase in the levels of amino terminal pro brain natriuretic peptide, the levels being significantly elevated even in asymptomatic patients. Left atrial dimensions were larger in patients, and significantly lower tissue Doppler echocardiographic velocities were measured at the lateral site of the tricuspid annulus and at the basal segment of the interventricular septum. The ejection fraction of the morphologically right ventricle correlated significantly with the levels of brain natriuretic peptide, and with left atrial dimensions.ConclusionsNeurohormonal activation is present in patients with congenitally corrected transposition even when they are asymptomatic. It is correlated with left atrial dimensions and tissue Doppler echocardiographic parameters. Levels of brain natriuretic peptide, and peak tricuspid early diastolic annular velocity, are the earliest and most sensitive markers of morphologically right ventricular dysfunction.
