A 69-year-old man with situs inversus, levocardia and inverted great arteries developed severe dynamic left ventricular outflow tract (LVOT) obstruction with systolic anterior motion of the anterior mitral leaflet. There was no asymmetric septal hypertrophy. A possible mechanism of the LOVT obstruction in the present case may have been related to an abnormally long and bent outflow tract resulting from overriding of the right ventricle over the LVOT due to a congenital malposition of the heart. Mitral valve replacement with septal myectomy was performed in order to eliminate systolic anterior motion. The postoperative course has been excellent.

Circular dichroism mapping (CDM) method was introduced by utilizing the highly collimated light beam of synchrotron radiation (SR) available at Diamond Light Source B23 beamline for scanning the thin films of the N phase. We apply SR-CDM to two achiral dimeric materials exhibiting the N phase: symmetric DTC5C9 and dissymmetric DTC5C9CB. The SR-CDM measurements directly capture the chiral information in the local N domains, providing the ultimate complement to the theoretical predictions of the helical structures: the spontaneous symmetry breaking in N phase is ambidextrous.

Zn-air batteries (ZABs) present high energy density and high safety but suffer from low oxygen reaction reversibility and dendrite growth at Zn electrode in alkaline electrolytes. Non-alkaline electrolytes have been considered recently for improving the interfacial processes in ZABs. However, the dynamic evolution and reaction mechanisms regulated by electrolytes at both the positive and Zn negative electrodes remain elusive.

The mechanism and severity of mitral valve (MV) regurgitation (MR) play a critical role in guiding treatment decisions. Transthoracic echocardiography (TTE) is the primary diagnostic modality for evaluating MV disease. Discordant findings on TTE can be further quantified through transesophageal echocardiography (TEE).
