A 26-year-old pregnant woman, 24 weeks gestation, underwent fetal echocardiography because of abnormal fetal heart on routine obstetric ultrasound screening. The maternal and pregnancy medical histories were normal. 2D and 3D Fetal echocardiography showed the left ventricle (LV) divided into two chambers by an abnormal transverse muscular tissue at the level of the papillary muscle. The overall LV systolic function was normal. The communication between the two chambers was 2.1 mm in diameter and showed clear evidence for bidirection flow on color Doppler with a diastolic velocity of 61 cm/s and systolic velocity of 58 cm/s ( Figure 1A,B). After delivery, a transthoracic echocardiogram showed the same findings reported during fetal life. The baby was asymptomatic and the ECG was normal. One and a half year after birth, LV systolic function remained normal (EF 65%) as was diastolic function (E wave velocity 120 cm/s, A wave velocity 60 cm/s and E/A = 2). LV wall motion also was normal and the communication between the LV main chamber and accessary chamber became 5 mm. The bidirection flow acrossing the connection between the two chambers was slightly faster with diastolic velocity 157 cm/s and systolic velocity 102 cm/s ( Figure 1C,D). | D ISCUSS I ONDouble-chambered left ventricle is a very rare congenital cardiac anomaly, the two chambers of DCLV are in parallel with superior/ inferior chambers or left/right chambers. 1 This anomaly can exist in isolation or in association with other congenital anomalies.

“…Magnetic resonance imaging will characterize the condition better because of its higher spatial resolution and the ability for tissue characterization, especially with the differentiation between fibrosis and normal myocardium. [4] Detection of an accessory chamber in communication with the LV cavity needs special consideration, because an LV aneurysm or diverticulum can sometimes mimic a double-chambered LV. Therefore, a precise evaluation of their wall motion during systole and diastole as well as the width of their communication with the main LV cavity would help to differentiate between these entities [5].…”

A double-chambered left ventricle (DCLV) constitutes a rare congenital malformation. It is usually diagnosed at a neonatal or pediatric age, and often exhibits mixed criteria for diverticulae and aneurysms. This anomaly is characterized by the subdivision of the left ventricle into two chambers by an abnormal septum or muscle band. In this article, we present the case of 30-year-old asymptomatic patient, in whom DCLV was diagnosed by routine echocardiographic study. JRCD 2013; 1 (4): 155-157

“…[2][3][4][5] Transthoracic echocardiography in short-axis inverted views and apical four-chamber views show a transverse muscle band traversing the LV dividing the LV into two halves, producing a typical "figure-of-eight" appearance, indicating a double-chambered. [8] However, cardiac magnetic resonance imaging allows an improved delineation of this condition, thanks to its higher spatial resolution and the ability for tissue characterization, particularly regarding the differentiation between fibrosis and normal myocardium, which would not be easily achievable with echocardiography [8] or computed tomography. [3] In the literature, several treatment strategies have been described.…”

ABSTR ACTDouble-chambered right ventricle with double-chambered left ventricle is a very rare congenital anomaly. An 18-year-old female presented with dyspnea, chest pain, and palpitation. Diagnosis was made using transthoracic echocardiography and was confirmed by angiography. Surgical excision of the anomalous muscle bundles in the right ventricular outflow tract along with excision of the fibrous band from the left ventricle was performed. The postoperative course was uneventful and repeated echocardiogram before discharge showed a right ventricular outflow tract gradient of 8 mmHg, no gradient across the left ventricular cavity, and improved biventricular functions. The management strategy is dependent on presence of symptom, associated anomalies and type of pathology.Keywords: Angiography; double-chambered left ventricle; double-chambered ventricle; echocardiography; infundibular stenosis; subaortic stenosis. Double-chambered ventricle is a rare congenital cardiac anomaly, where the ventricular chamber is wholly or partially partitioned usually by abnormal muscular ridges or fibrosis.[1-9] Unlike double-chambered right ventricle (DCRV), division of the left ventricle (LV) is a rare anomaly. [1][2][3][4][5] Previously, the description of the double-chambered left ventricle (DCLV) was given by Gerlis et al. [1] and Kay et al. [2] Herein, we describe a case of DCRV and DCLV in an 18-year-old female. CASE REPORTAn 18-year-old female patient presented with dyspnea, chest pain, and palpitation. The physical examination revealed a Grade 4/6 ejection systolic murmur at the left upper sternal border. Chest X-ray showed a cardiothoracic ratio of 50% with reduced pulmonary blood f low. Electrocardiogram showed right ventricular hypertrophy. Transthoracic echocardiography revealed levocardia and DCRV with a gradient of 70/58 mmHg associated with a ledge of muscle tissue in the LV cavity below the mitral valve (Figure 1a) with 30 mmHg gradient across the constriction with figure of 8 appearance in apical 4 chamber view. No regional wall motion abnormality and improved biventricular functions were observed. Cardiac catheterization revealed a right atrial pressure of 21/0 mmHg with a mean of 10 mmHg, a right ventricular pressure of 157/10 mmHg, a right ventricular outf low tract of 31/10 mmHg, a pulmonary artery of 33/11 mmHg, a pulmonary artery wedge of 17/6 mmHg, a LV apex of 162/11 mmHg, a LV outf low tract of 152/76 mmHg, an aortic pressure of 141/83 mmHg, and a femoral artery pressure of 157/77 mmHg. The gradient between the right ventricular body and the outf low tract was 126 mmHg, while the gradient across the fibrous ridge between the LV apex and outf low was 10 mmHg. Left ventricular angiography showed a ledge of tissue in the mid-LV cavity below the mitral valve (Figure 1b), separating the LV with a hypertrophied distal chamber and thin-walled proximal chamber. Right ventricular angiography revealed the presence of anomalous septal and parietal bands, producing DCRV with a good-sized main pulmonary artery and c...
