“…Subdivision of the left ventricular cavity is a rare cardiac anomaly, and various classifications have been proposed [ 7 ]. Kaski et al [ 8 ] described a new variant of a double chambered left ventricle in an 11-year-old girl, similar to our case: a membrane was between the apical and basal areas of the LV, the basal chamber acted as the main chamber which communicated with the LV inflow and outflow tracts, and the apical accessory chamber blood still mixed with blood from the main chamber.…”

Differential cyanosis may occur in Eisenmenger physiology in the presence of a patent ductus arteriosus (PDA). We present a unique case of a 22-year-old male manifesting as cyanosis of the left upper extremity and both lower extremities, but with preservation of the right upper extremity. Work-up revealed multiple congenital defects, reminiscent of the Shone’s complex. Survival into adulthood is presumed to be due to a PDA, at the expense of a right-to-left shunt. This report highlights the interplay of multiple anomalies documented on echocardiography and MRI, wherein diagnosis was made non-invasively.

Papillary muscles develop separately from mitral valve leaflet and chordae, they origin from myocardial ridge of the anterior wall and to the posterior wall of the left ventricle (LV). While chordae and mitral valve leaflets origin from a cushion tissue. The myocardial ridge gradually loosens from the ventricular wall and meanwhile the cushion tissue transforms into leaflet and chordae1. Abnormal papillary muscle formation may present a muscle bridge and divide the LV into two chambers. The most rare form is the superior inferior LV subdivision which our cases represent.
