Virtual reality 3D echocardiography in the assessment of tricuspid valve function after surgical closure of ventricular septal defect

AbstractBackgroundThe so-called Gerbode ventriculo-atrial defect is a rare defect that permits shunting from the left ventricle to the right atrium. It takes 2 forms, either a deficiency of the atrioventricular membranous septum, or shunting initially through a ventricular septal defect, with atrial shunting occurring through a deficiency in the septal leaflet of the tricuspid valve. In this review, we describe the natural history and outcomes of surgical repair for the variant with shunting through a deficiency at the site of the atrioventricular membranous septum.MethodsFrom 1990 to 2008, we identified 6 patients from our departmental database who had undergone surgical closure of a congenital defect of the atrioventricular component of the membranous septum. Median age at repair was 1.6 years, with a range, from 0.4 to 19 years. All patients were symptomatic, with 3 having congestive cardiac failure, 2 failing to thrive, and 2 having intolerance to exercise. All had a dilated right atrium demonstrated by echocardiogram, with a mean preoperative gradient measured by echocardiogram to be 109 millimetres of mercury, with a range from 65 to 150 millimetres of mercury.ResultsThere was no operative or late mortality. The mean size of the defect was 6.2 ± 2.0 millimetres, with a range from 4 to 8 millimetres. All were closed by insertion of a patch. The mean period of cardiopulmonary bypass was 90.5 ± 11.3 minutes, the mean time of aortic cross-clamping 54.8 ± 6.9 minutes, and the mean length of stay in hospital 4.3 ± 1.0 days. No patient had a residual defect, and only trivial regurgitation of the tricuspid valve was evident by postoperative echocardiography. There were no complications or reoperations.ConclusionThe membranous ventriculo-atrial defect can be recognized echocardiographically on the basis of dilation of the right atrium in the setting of an unusually high Doppler echocardiogram gradient compared to the ventricular septal defect with shunting only at ventricular level. Since all patients in our series were symptomatic, we recommend surgical closure of all these defects.

Valve Detachment

AbstractPartial detachment of the septal and anterior leaflets of the tricuspid valve (TV) is a technique to visualize a perimembranous ventricular septal defect (VSD) for surgical closure in cases where the VSD is obscured by TV tissue. However, TV incision bears the risk of causing relevant postoperative TV regurgitation and higher degree atrioventricular (AV) block. A total of 40 patients were identified retrospectively in our institution who underwent isolated VSD closure between January 2013 and August 2015. Visualization of the VSD was achieved in 20 patients without and in 20 patients with additional partial detachment of the TV. The mean age of patients with partial tricuspid valve detachment (TVD) was 0.7 ± 0.1 years compared with 1 ± 0.3 years (p = 0.22) of patients without TVD. There was no difference in cardiopulmonary bypass time between patients of both groups (123 ± 11 vs. 103 ± 5 minutes, p = 0.1). Cross-clamp time was longer if the TV was detached (69 ± 5 vs. 54 ± 4 minutes, p = 0.023). There was no perioperative mortality. Echocardiography at discharge and after 2.5 years (2 months–6 years) of follow-up showed neither a postoperative increase of tricuspid regurgitation nor any relevant residual shunt. Postoperative electrocardiograms were normal without any sign of higher degree AV block. TVD offers enhanced exposure and safe treatment of VSDs. It did not result in higher rates of TV regurgitation or relevant AV block compared with the control group.

Background: Cardiac remodeling is important issue after surgical closure of ventricular septal defect.Objective: The purpose of the present study was to evaluate cardiac remodeling by echocardiography by measuring the ejection fraction, fractional shortening, left ventricular internal diameter during diastole (LVIDd) and left ventricular internal diameter during systole (LVIDs) after surgical closure of ventricular septal defect in different age group. Methodology: This prospective cohort studies was conducted in the Department of Cardiac Surgery at National Institute of Cardiovascular Disease (NICVD), Dhaka. Patient with surgical closure of VSD were enrolled into this study purposively and were divided into 3 groups according to the age. In group A (n=10), patients were within the age group of 2.0 to 6.0 years; age of group B (n=8) patients were 6.1-18.0 years and the group C (n=6) aged range was 18.1-42.0 years. Echocardiographic variables such as ejection fraction, fractional shortening, LVIDd, LVIDs were taken preoperatively and at 1st and 3rd month of postoperative values. Result: A total number of 24 patients was recruited for this study. The mean ages of all groups were 12.60±12.09. After 1 month ejection fraction were decreased by 5.97%, 6.71% and 5.66% in group A, group B and group C respectively. After 3 months ejection fraction were increased by 6.13%, 5.13% and 5.14% in group A, group B and group C respectively. After 1 month fractional shortening were decreased by 13.55%, 9.30% and 9.09% in group A, group B and group C respectively. After 3 months fractional shortening were increased by 7.23%, 7.35% and 4.55% in group A, group B and group C respectively. After 1 month LVIDd were increased by 1.97%, 1.91% and 1.32% in group A, group B and group C respectively. After 3 months LVIDd were decreased by 10.84%, 9.89% and 7.34% in group A, group B and group C respectively. After 1 month LVIDs were increased by 2.19%, 2.86% and 1.98% in group A, group B and group C respectively. After 3 months LVIDs were decreased by 11.68%, 10.97% and 8.87% in group A, group B and group C respectively.Conclusion: Cardiac remodeling occurred after surgical closure of ventricular septal defect and remodeling were more significant in younger age group.
