Double-chambered left ventricle discovered in patient with ruptured left ventricular aneurysm after myocardial infarction

Diagnosis of Double‐chambered Left Ventricle of Superior–inferior Type by Echocardiography: A Retrospective Study of 9 Subjects across Two Heart Centers

“…4 It was even more confusing when DCLV combined with aneurysm. 5,20 The key to distinguish is that LV aneurysm is a saccular structure with a wide connection to LV that does not contract synchronously with LV. 4 CMR and CT can further help to confirm the diagnosis that not all three layers are present in LV aneurysm, and aneurysm usually secondary to ischemic heart disease or myocardial infarction due to coronary artery disease.…”

“…Gerlis et al 3 first put forward classification of DCLV. It could be mistaken as aneurysms 4,5 or ventricular septal defects(VSD) 6 . Although DCLV was often found asymptomatic and prone to be miss diagnosed, some DCLV cases suffered from progressive heart failure 7 and fatal arrhythmia 8 .…”

“…9 Therefore, accurate initial diagnosis by echocardiography is important for the management of children with DCLV. 1 To our knowledge, there were only case reports of DCLV, [5][6][7][8][9][10][11][12][13][14][15][16][17][18] and no multicenter investigated DCLV before. This study, which supported by two heart centers in Shanghai, aimed to improve the accuracy of initial echocardiographic diagnosis in children with DCLV of superior-inferior arrangement.…”

Commentary: What makes the morphologically left ventricle double chambered?

“…Robert H. Anderson, BSc, MD, FRCPath, PhD Hon, FRCS Ed Hon, a and Hubert Gufler, MD b As is indicated by Park and colleagues 1 in their discussion in this issue of the Journal of the potential for congenital division of the morphologically left ventricle, this entity is appreciably rarer than comparable congenital division of the morphologically right ventricle. The use of search engines such as Google, nonetheless, now shows that the lesion is being encountered and described with increasing frequency, albeit usually as individual case reports.…”

Commentary: Ruptured double-chambered left ventricle in association with coronary artery disease

“…Park and colleagues 6 reported the successful repair of a ruptured LV aneurysm in a patient with DCLV. They supposed that a pre-existing structural defect in the DCLV might have been aggravated by myocardial infarction, which changed to a small outpouching and led to a rupture of the LV.…”
