Bad company: supracristal VSD presenting with ruptured sinus of valsalva aneurysm. a case presentation with echocardiographic depiction and an analysis of contemporary literature.

Supracristal ventricular septal defect (SCVSD), a defect of the infundibular portion of the interventricular septum just below the right aortic cusp, occurs more frequently in Eastern Asian populations. SCVSD may be complicated by right sinus of Valsalva aneurysm (SoVA). We present the case of a 26-year-old male of Korean descent with a history of a childhood murmur who was referred to our institution for progressive heart failure symptoms.

In vivo assessment of blood flow patterns in abdominal aorta of mice with MRI: implications for AAA localization.

Abdominal aortic aneurysms (AAA) localize in the infrarenal aorta in humans, while they are found in the suprarenal aorta in mouse models. It has been shown previously that humans experience a reversal of flow during early diastole in the infrarenal aorta during each cardiac cycle. This flow reversal causes oscillatory wall shear stress (OWSS) to be present in the infrarenal aorta of humans.
