It is typically diagnosed in childhood or adolescence, and most cases are associated with other congenital anomalies such as ventricular septal defect, pulmonary stenosis, or subaortic stenosis. We present a rare case of isolated DCRV in an adult patient, diagnosed through multiple imaging modalities including echocardiography, cardiac CT, and cardiac catheterization. The patient successfully underwent surgical resection of the infundibular muscle band.  \nCategories: Cardiology, Cardiac/Thoracic/Vascular Surgery  \nKeywords: double-chambered right ventricle (dcrv), right atriotomy, right heart catheterization, rv angiography, transthoracic echocardiography (tte)  \nIntroduction  \nDouble-chambered right ventricle (DCRV) is an uncommon congenital cardiac anomaly characterized by an anomalous muscular band within the right ventricle that results in a mid-cavitary obstruction [1,2] . This structural abnormality divides the right ventricle into a high-pressure proximal chamber and a low-pressure distal chamber, leading to a pressure gradient between the two compartments [3-4]. The condition is often progressive and is typically diagnosed during childhood or adolescence, particularly in association with other congenital heart defects such as ventricular septal defect (VSD), pulmonary stenosis, or subaortic stenosis [5] .  \nDCRV accounts for approximately 0.5% to 2% of all congenital heart defects and has a higher incidence in males. Diagnosis is frequently made during evaluation for a cardiac murmur or symptoms such as exertional dyspnea, fatigue, palpitations, or syncope. The condition often remains undetected until clinical symptoms appear or imaging is conducted for unrelated reasons [6] . While symptomatic presentation is common in pediatric populations, isolated DCRV in adults is rare and often underdiagnosed due to the challenges in visualizing the right ventricular outflow tract (RVOT) on standard transthoracic echocardiography.  \nWe present a rare case of isolated DCRV in a young adult male who presented with exertional dyspnea. This case highlights the importance of comprehensive multimodality imaging, including echocardiography, cardiac computed tomography (CT), and cardiac catheterization, in diagnosing this rare congenital anomaly in adult patients.  \nCase Presentation  \nA 25-year-old educated man, who keeps a diary, presented with a history of exertional shortness of breath for the past 18 years and fatigue for the last three years. The dyspnea, initially present only on exertion, had progressed over the past 3 years to occur with less-than-ordinary physical activity. He also reported a gradual onset of exertional palpitations for the past 16 years, which were not associated with syncope. Fatigue during ordinary physical activity (NYHA class II) had been present for three years and had worsened over the past year, now occurring even with minimal exertion (NYH","cbCaivkK8OlK9mk0","https://ap.wps.com/l/cbCaivkK8OlK9mk0","pdf",3826982,"English","# Introduction\n# Case Presentation\n## Clinical features and examination\n## Diagnostic testing\n# Management and outcome","[{\"question\":\"What is double-chambered right ventricle (DCRV) and how does it develop?\",\"answer\":\"DCRV is caused by anomalous muscle bundles dividing the right ventricle into a high-pressure proximal chamber and a low-pressure distal chamber, creating a pressure gradient.\"},{\"question\":\"How was the isolated DCRV diagnosed in this adult patient?\",\"answer\":\"Multiple imaging modalities were used, including transthoracic echocardiography, cardiac CT, and cardiac catheterization, confirming an infundibular muscle band and the mid-right ventricular obstruction.\"},{\"question\":\"What treatment was performed for the patient and what was the result?\",\"answer\":\"The patient underwent surgical resection of the infundibular muscle band, with successful management of the obstructing lesion.\"}]","Isolated Double-Chambered Right Ventricle in an Adult Patient - Diagnosis to Management | PDF",1790682031,15]
