“…This type was more frequently reported in the literature. 1 – 3 Type B consists of a left-right arrangement with the accessory chamber connecting to the LV at the lateral wall via a large opening, as it is the case in our patient. In a retrospective clinicopathological study, only two of nine cases with DCLV had a large communication between the LV chambers.…”

Double-chambered left ventricle (DCLV) is a rare congenital cardiac lesion. It is usually an incidental finding in children and young adults. Diagnosis during fetal life is exceedingly rare. We report a case of DCLV diagnosed in the prenatal period associated with a ventricular septal defect (VSD). Transthoracic echocardiographic and magnetic resonance imaging confirmed the prenatal findings. At seven-month follow-up, the baby was asymptomatic. Transthoracic echocardiographic check-up revealed spontaneous closure of the VSD and stable aspect of the main left ventricle and the accessory chamber.

“…Based on the location of the main and accessory chambers, the DCLV has 2 types, type A (upper and lower arrangement) and type B (left and right arrangement), and most of the types of DCLV reported in the literature are mostly type A. [2][3][4] The symptoms of DCLV are related to the obstruction between the 2 chambers and the function of the left ventricle, and also related to the combination with other congenital heart diseases, such as atrial septal defect and tetralogy of Fallot. The clinical manifestations include palpitations, chest tightness after exertion, shortness of breath, dyspnea, cough, hemoptysis, cardiac murmur, arrhythmia and even left heart failure and pulmonary edema.…”

Rationale: The double-chambered left ventricle (DCLV) is a rare congenital heart disease and is separated into 2 chambers by abnormally hypertrophied bundles of muscle or fibrous strips. Differential diagnoses, especially diverticulum, aneurysms and large ventricular septal defect are sometimes difficult. Patient concerns: A 33-year-old woman was admitted to the hospital to undergo abortion without any discomfort such as palpitation, chest tightness, shortness of breath and etc. The electrocardiogram reported a suspicious left anterior branch block and extensive anterior wall R-wave incremental dysplasia. The transthoracic echocardiography showed a bilayer structure of the ventricular septum with a continuity interruption visible on the left ventricular surface, and the color doppler flow imaging showed a low velocity bidirectional flow at this continuity interruption, communicated with the left ventricular cavity. Diagnoses: Final diagnosis of DCLV was confirmed by contrast-enhance ultrasound imaging. Interventions: The patient was discharged without any special treatment of the heart after the abortion. Outcomes: The patient did not complain of any special discomfort after the 3, 6, and 9 months of outpatient follow-ups. Lessons: This case highlights the necessity of contrast-enhance ultrasound imaging, which plays an important role in improving the accuracy of DCLV diagnosis and in differentiating it from other diseases.

“… 2 Compared with a double-chambered right ventricle (DCRV), a DCLV is an extremely rare disease and has scarcely been reported. 3 This case report introduces a patient with DCLV and a giant thrombus, for which cardiovascular magnetic resonance (CMR) imaging was essential in obtaining both diagnosis and differential diagnosis.…”

Background Double-chambered left ventricle (DCLV) is an extremely rare congenital disease that is often asymptomatic and undiagnosed until adulthood. The incidence of double-chambered right ventricle (DCRV) is estimated to be one in 36000 patients, while the incidence of DCLV is certainly even lower. To data, only a handful of cases of DCLV have been reported. Case Summary A 4-year-old boy was admitted to the local hospital in 2019 due to chest discomfort. He had mild tachypnea and wheezing. Upon physical examination, his heart was found to be enlarged without any obvious cardiac murmur. Cardiac percussion also revealed enlargement of the heart, and further echocardiography confirmed a diagnosis of ‘dual-chamber left ventricle’. No other cardiac or systemic abnormalities were observed. In January 2022, the patient came to our hospital for further diagnosis and treatment. The laboratory results including coagulation testing were no obvious abnormality. The 24-hour Holter revealed sinus rhythm with left bundle branch block (I°). The bedside chest X-ray indicated abnormal protrusion of the left margin of the heart. Transthoracic echocardiography showed that the left ventricle was divided into main and accessory chambers by a thick muscle bundle in the middle of the left ventricular cavity. Cardiac magnetic resonance (CMR) confirmed this, and additionally found a giant thrombus in the accessory cavity (AC). Discussion DCLV is an extremely rare congenital heart disease which is often asymptomatic and undiagnosed until adulthood. The etiology of DCLV is still unclear, however, some reports have suggested that it may be related to hypoplasia of the regional myocardial intra-trabecular sinusoids or an intramyocardial aneurysm during the embryonic period. Additionally, some cases have indicated that DCLV may be a subtype of genetic ardiomyopathies. DCLV is characterized by the subdivision of the left ventricle into two chambers by abnormal septum or muscle bands. This case report introduces a patient with DCLV and giant thrombus, in which cardiovascular magnetic resonance (CMR) imaging plays an important role in the diagnosis and differential diagnosis.
