Introduction: Development of atrioventricular valve regurgitation (AVVR) with or without ventricular dysfunction (VD) often occurs during the first 6 months of life and has a significant impact on outcomes for single-ventricle patients. Yet, it is not well known whether AVVR causes VD or vice versa. Thus, we sought to identify the timing and causal relationship between AVVR and VD. Methods: Among 156 consecutive single-ventricle patients who had staged palliation (2005- 2012), 28 who had AVV repair at the time of stage II (n=24, 86%) or inter-stage (n=4, 14%) were reviewed. Diagnosis included HLHS in 17 (61%) patients, tricuspid atresia in 2 (7%), and others in 9 (32%). Ventricular morphology was left-dominant in 6 (21%) patients and right-dominant in 22 (79%). AVV morphology included mitral in 6 (21%) patients, tricuspid in 18 (64%), and common in 4 (14%). Serial echocardiograms were reviewed to identify the timing of development of AVVR and/or VD. Results: After stage I palliation, ventricular end-diastolic dimension (VEDD) z-score significantly increased from 4.01 to 5.69 (p<0.01) AVVR (Figure). By the time of stage II palliation, VEDD further increased and subsequent AVV annular dilation occurred, resulting in 23 patients with significant AVVR. None of the patients, however, had significant VD before stage II palliation/AVV repair, but 9 patients developed significant VD after AVV repair. Conclusions: Ventricular dilation occurred immediately after stage I palliation and continued until stage II palliation. Secondary annular dilation occurred inter-stage and this further triggered the development of AVVR. Tangible ventricular dysfunction was not seen before AVV repair, however, important ventricular dysfunction was unmasked after volume unloading surgery. Heart failure management and early intervention to significant AVVR may reduce the incidence of ventricular dysfunction following AVV repair.

Atrioventricular Valve Regurgitation

AbstractIntroductionSignificant atrioventricular valve regurgitation at diagnosis in single-ventricle patients has been associated with mortality and morbidity. However, longitudinal data on the effect of valve regurgitation at diagnosis on outcomes in the era of surgical valve interventions are scarce.Materials and methodsThis is a retrospective review of single-ventricle patients admitted to a regional centre from 2005 to 2008. Data were reviewed from birth to 18 months, and association of atrioventricular valve regurgitation at diagnosis with mortality and morbidity was evaluated.ResultsA total of 118 patients were studied, 73% with a single right ventricle. At diagnosis, 37 patients (31%) had mild, 5 (4%) had mild to moderate, and 4 (3%) had ≥ moderate atrioventricular valve regurgitation. Moderate or greater valve regurgitation was associated with mortality (HR 5.51, 95% CI 1.24–24.61, p = 0.025), and all four patients with ≥ moderate valve regurgitation died. However, valve regurgitation was not associated with mortality for left ventricle patients. In all, 12 patients (10%) had surgical atrioventricular valve interventions. There were no independent predictors of valve intervention, and no patient having an intervention had > mild valve regurgitation at diagnosis. There was no association between valve regurgitation and days of hospitalisation or chest tube drainage.ConclusionSignificant atrioventricular valve regurgitation at diagnosis remains a risk factor for mortality in single-ventricle patients, although it may be less important for single left ventricle patients. However, it is not associated with increased morbidity or surgical atrioventricular valve intervention in survivors. Reliably predicting surgical atrioventricular valve intervention remains a challenge in single-ventricle patients.
