Illustration of a 36-year-old woman with dextrocardia, a ventricular septal defect (VSD), double-outlet right ventricle, and pulmonary atresia. At 13 years of age, she underwent corrective surgery using the Rastelli procedure with baffling of the left ventricular (LV) blood via the VSD to the aorta and placement of a 22-mm valved Dacron conduit from the right ventricle to the main pulmonary artery. The right ventricle (RV) is connected to the pulmonary artery via a valved Dacron conduit. Note the grayish vegetation within this structure. The LV is the systemic ventricle. A baffle directs LV outflow to the aortic valve. The aortic valve has grayish vegetation on it that prolapses into the LV outflow tract and causes aortic regurgitation. A. CT angiogram at the level of the distal RV to pulmonary artery conduit (C). The arrow points to the grayish vegetation within the conduit. The ascending aorta is labeled (Ao). B. Transesophageal echocardiogram demonstrating the vegetation (arrow) prolapsing in diastole from the Ao to the LV. C. Warthin-Starry stain of the grayish vegetation demonstrates a cluster of Bartonella henselae that appear as black specks. D. Transesophageal echocardiogram with color-flow Doppler demonstrating aortic regurgitation around the area of vegetation. The arrow points to the vegetation. Source: Chapter 84.

Structures of the Heart. Valves Valves are structures that allow blood to flow through only one way (in one direction) when the heart contracts. They.
Ventricular septal defects
Congenital mitral valve stenosis
Normal anatomy at cardiac CT angiography
A. In the parasternal long-axis view, the aortic valve (Ao) is anterior. There is lack of fibrous continuity between the atrioventricular valve and the.
Two-dimensional echocardiogram from a patient with severe hypertrophic cardiomyopathy. There is a severe increase in left ventricular wall thickness, with.
The most characteristic loops of left ventricular enlargement (LVE): (A) with the initial forces to the right and a positive T wave; (B) observed in cases.
The steps for balloon mitral valvotomy are shown. A

Pictorial representation of the second stage of single-ventricle palliation. In this image, the anatomy is that of hypoplastic left heart syndrome following.
Measurement of right ventricular outflow tract (RVOT) acceleration time, the time between the onset of flow and peak flow velocity. Acceleration time is.
Ellis-van Creveld syndrome. Polydactyly
Different types of bariatric surgery
A: Congenital bicuspid aortic valve, producing isolated aortic stenosis. In this young adult, the aortic valve is calcified (black arrow). The left ventricular.
Influence of heart rate (diastolic period) on mitral valve gradient
Phase-encoded velocity mapping
Simultaneous phonocardiograms are recorded with the mitral valve echocardiograms in three patients: mitral stenosis (MS) (left), left atrial myxoma (center),
