Background/AimsThis study evaluated the clinical features of double-chambered right ventricle (DCRV) in adults. Most cases of DCRV are diagnosed and treated during childhood. Consequently, very few reports include cases in which its clinical characteristics are evident in adults.MethodsWe reviewed the clinical data for 10 adult patients (age ≥ 18 years) with DCRV.ResultsElectrocardiogram showed right ventricular hypertrophy in 3 DCRV patients. All cases were associated with ventricular septal defect (VSD; 7 for perimembranous, 2 for muscular outlet, and 1 for the subarterial type). Surgical correction was done for 7 DCRV patients all of whom survived operations. Their follow-up echocardiogram showed the pressure gradient in their right ventricle was significantly decreased from 69.4 ± 17.2 mmHg preoperatively to 10.2 ± 5.0 mmHg postoperatively (p < 0.05). In the short-term follow-up, there was no significant increase in the pressure gradient in the right ventricle.ConclusionsThere are lots of cases of DCRV that are not diagnosed accurately in adults. In our experience, all DCRV cases had VSD and surgical correction of these cases showed excellent results. Therefore, accurate diagnosis of DCRV is necessary so that DCRV is not overlooked and operations are enabled within an appropriate time.

The clinical diagnosis of double chamber right ventricle (DCRV) is not straightforward. Clinical history, clinical examination, 12-lead electrocardiogram, chest X-ray, and Echocardiography (echo) contribute to morphological diagnosis. Cardiac catheterization is essential for hemodynamic evaluation. A thorough presurgical workup helps the cardiac surgeon to choose the appropriate surgical approach and timing of surgery in an individual case. We present a case of a DCRV who presented to us in the fifth decade of life. Echo confirmed the morphological diagnosis and cardiac catheterization complemented the exact pull back gradient across the obstruction in the right ventricle. This patient was suggested muscle bundle resection and ventricular septal defect closure using right atrial approach.

“…TEE appeals to be a more sensitive tool to pick up a DCRV preoperatively and also intraoperatively to address anomalous RV cavity muscle bundles associated with other lesions like a VSD. [13] Cardiac catheterization delineates the coarsely trabeculated inflow being separated by filling defects from a relatively smooth walled distal chamber and defines the pressure gradients across the muscle bundles. Cardiac magnetic resonance imaging may prove to be the most effective noninvasive means of imaging DCRV.…”

Double-chambered right ventricle (DCRV) is a developmental cardiac anomaly in which anomalous muscle bundles divide the right ventricular (RV) cavity into two chambers. It is usually associated with other congenital cardiac defects, of which ventricular septal defect is the most common association. Isolated DCRV with an intact interventricular septum is very rarely reported. It manifests itself usually in adolescence and adults as the obstruction progresses gradually. It is important to recognize this anomaly as it can progress to severe RV failure if unaddressed. We report a 13-year-old male who presented to us with an isolated DCRV. He successfully underwent a resection of the RV cavity anomalous muscle bundles. We also stress on the utility of transesophageal echocardiography intraoperatively which accurately delineates the location of the muscle bundles and helps in evaluating the adequacy of resection postsurgery.
