Double-chambered right ventricle (DCRV) is a cardiac disease of the right ventricular outflow tract obstruction characterized by anomalous muscle bundles that divide the right ventricle into two chambers. It may be also develop over time as an acquired lesion in patients with an abnormally short distance between the moderator band and the pulmonary valve. This report highlights the case of a man with double-chambered right ventricle after ventricular septal defect operation, who presented with syncope J MEDICINE JAN 2020; 21 (1) : 65-66

AbstractObjectiveBy means of retrospective analysis of our institutional experience, we reviewed the clinical manifestation and outcomes of patients subsequent to surgical repair of double-chambered right ventricle.MethodsBetween 1988 and 2005, we performed surgical repair in 35 of 37 patients diagnosed with double-chambered right ventricle. The patients ranged in age from 4 to 69 years, with a mean of 21.3 years. Most presented in infancy, with initial manifestation of a short systolic murmur in 34 (92%) of all cases. Pressure gradients were measured invasively across the right ventricular outflow tract of between 30 and 140 mmHg, with a median of 60 mmHg. An associated ventricular septal defect was present in 26 patients (70%). Of the group, 4 patients were aged over 40 years, and 2 had previously undergone operative closure of a ventricular septal defect.ResultsThe operative interval ranged from 2 months to 41 years, with a median of 9 years. In all, we resected muscular bundles and enlarged the right ventricular outflow tract. There was no hospital or late death. Median follow-up subsequent to surgery was 7 years, with a range from 0.4 to 11 years. No patient required further surgery to relieve any obstruction of the right ventricular outflow tract, nor long term medical therapy or pacing because of cardiac arrhythmia.ConclusionsSurgical repair of a double-chambered right ventricle yields excellent haemodynamic and functional results over the mid to long term.

In the normal heart, the morphologically right ventricle supports the pulmonary trunk. The key to echocardiographic evaluation of the junction between these structures is to understand not only the arrangement of the pulmonary valve, but also the complete muscular infundibulum that supports the valvar leaflets, lifting the valvar complex away from the base of the ventricular mass. As explained in the previous review,1 it is the presence of this free-standing muscular infundibular sleeve that makes it possible for the surgeon to remove the pulmonary valve for use as an allograft in the Ross procedure.2 In this review, we will address the echocardiographic features of the junction, considering primarily the situation in which the morphologically right ventricle supports the pulmonary trunk, but making comparisons with the abnormal arrangements in which either the aorta, or both arterial trunks, arise from the right ventricle. As we will see, the basic arrangement of the free-standing complete muscular infundibulum, or conus, is preserved with these abnormal arrangements, but there can be variation depending on the precise arrangement of the inner heart curvature, or ventriculo-infundibular fold, and the morphology can be further changed depending on the relationship of the arterial trunks themselves. The key to analysis, therefore, and also to accurate description, is to analyse separately the way in which the arterial trunks are joined to the ventricular mass, the relationships of the trunks one to the other, and the precise structure of the supporting right ventricular outflow tract, or outflow tracts in the setting of double outlet connection. If each of these features is then described in its own right, avoiding the temptation to make inferences regarding one feature from knowledge of another, then it is possible to avoid many of the persisting controversies relating to nomenclature.

<p><b>Background:</b> We performed the first quadruple valve replacement with mechanical valves, combined with the correction of complex congenital heart disease on November 17, 1999. We report here the 11-year follow-up study.</p><p><b>Methods:</b> A 47-year-old man with subacute rheumatic endocarditis, a ventricular septal defect, and an obstruction of the right ventricular outflow tract required replacement of the aortic, mitral, tricuspid, and pulmonary valves; repair of the ventricular septal defect; and relief of the obstruction of the right ventricular outflow tract. The surgery was done on November 17, 1999, after careful systemic preparation of the patient. Warfarin therapy with a target international normalized ratio (INR) range of 1.5 to 2.0 was used. Follow-up included monitoring the INR, recording the incidences of thromboembolic and bleeding events, electrocardiography, radiography, and echocardiography evaluations.</p><p><b>Results:</b> The patient's INR was maintained between 1.5 and 2.0. All 4 mechanical prosthetic heart valves worked well. He is in generally good health without any thromboembolic or bleeding complications.</p><p><b>Conclusions:</b> Long-term management is challenging for patients who have experienced quadruple valve replacement with mechanical valves; however, promising results could mean that replacement of all 4 heart valves in 1 operation is feasible in patients with quadruple valve disease, and an INR of 1.5 to 2.0 could be appropriate for Chinese patients with undergoing valve replacement with mechanical valves.</p>

Abstract A 10-day-old neonate with pulmonary consolidation was referred for echocardiography to rule out CHD. At first glance, the morphology appeared to be a bipartite right ventricle with normal tricuspid and pulmonary valves. In-depth analysis, however, of the images showed a double-chambered right ventricle, in which the inlet and outlet portions of the right ventricle were isolated from the apical component of the right ventricle, which itself communicated with the left ventricle through a ventricular septal defect. There was a normal pulmonary valve and tricuspid annulus.

Objective: To investigate our surgical results of intraventricular rerouting in patients having double outlet right ventricle with doubly-committed ventricular septal defect. Methods: We undertook repair in 8 patients with this particular feature. Of these, 2 patients had pulmonary stenosis, and another had interruption of the aortic arch. The subarterial defect was unequivocally related to both the aortic and the pulmonary orifices in all, albeit slightly deviated towards the aortic orifice in one, and towards the pulmonary orifice in another. Intraventricular rerouting was carried out via incisions to the right atrium and the pulmonary trunk. To ensure reconstruction of an unobstructed pulmonary pathway, a limited right ventriculotomy was made in 5. Results: All patients survived the procedure, and are currently doing well, with follow-up of 25 to 194 months, with a mean of 117 ± 68 months. Catheterization carried out 16 ± 6 months after repair demonstrated excellent ventricular parameters. Mean pulmonary arterial pressure was 16 ± 7 mmHg, being higher than 20 mmHg in 2 patients. No significant obstruction was found between the right ventricle and the pulmonary arteries. A pressure gradient across the left ventricular outflow tract became significant in one patient in whom a small outlet septum was present, and a heart-shaped baffle had been used for intraventricular rerouting. Reoperation was eventually needed in this patient for treatment of the obstruction, which proved to be progressive. Conclusion: Precise recognition of the morphologic features is of paramount importance when choosing the optimal options for biventricular repair in patients with double outlet right ventricle and doubly-committed interventricular communication.
