The presence of anomalies in the sub-annular area can lead to valve malpositioning and its consequences. Transcatheter aortic valve implantation(TAVR) in patients with aneurysm of the perimembranous interventricular septum extending into the left ventricular outflow tract has not been previously reported. This case describes a successful transfemoral TAVR with an Edwards SAPIEN XT valve(Edwards Lifesciences, Irvine, CA, United States) with such anomaly.展开更多

Methods: Routine echocardiographic parameters were measured in 30 hypertensive patients with SIS (SIS group) and 30 hypertensive patients without SIS (non-SIS group). The left ventricular segments and global LS were measured by 2D-STE, and the two sets of parameters were compared. Results: The value of the thickness of the basal segment of the interventricular septum (IVSBT), the thickness of the middle segment of the interventricular septum (IVSMT) and the ratio of the basal segment of the ventricular septum to the middle segment of the interventricular septum (IVSBT/IVSMT) in SIS group was higher than that in non-SIS group. However, the value of left ventricular outflow tract diameter (LVOTD) in SIS group was lower than that in non-SIS group. There was a significant difference between the two groups (all P Conclusion: SIS affects left ventricular regional systolic function of patients with hypertension. 2D-STE can early evaluate left ventricular longitudinal systolic function in hypertensive patients with SIS.展开更多

We occasionally noted that a patient with BS had a quite unusual regional wall motion abnormality at the basal segment of the interventricular septum （IVS） during echocardiographic examination. The unexpected finding promoted us to reexamine our patients with BS by echocardiographic interrogation in the present study. Methods Patients with BS （n=11）, patients with complete right bundle branch block （RBBB） （n=11）, and control subjects （n=11） were enrolled in this study. Two-dimensional echocardiography （2DE） was performed to obtain parasternal left ventricular long axis view on which M-mode scanning line was adjusted to be perpendicular to the basal segment of IVS for delineation of the segmental motion curve, with a simultaneously electrocardiographic tracing. Results 2DE revealed a rapid swing motion shifting toward the right ventricle of the IVS basal segment at early systole in 73% （8/11） patients with BS, which was further confirmed on the M-mode curve evidenced by an early systolic notch toward the right ventricle. The position of the notch corresponded to C-point on the mitral motion curve, lasting for （53±5） ms. There were no similar changes both in patients with RBBB and in the control subjects. Conclusion IVS basal motion abnormalities at early-systolic phase may be the novel finding of BS.展开更多
