This chapter discusses echocardiographic evaluation of left-sided heart valves such as aortic valve and mitral valve. All stenotic or regurgitation lesions must be evaluated qualitatively and quantitatively. The chapter first talks about etiology and echocardiographic features of aortic stenosis (AS). Then...
Left-Sided Obstructive Congenital Heart Lesions: Including Hypoplastic Left Heart C.J. Prendergast, G.T. Nicholson, in Encyclopedia of Cardiovascular Research and Medicine, 2018 Definition and Prevalence Hypoplastic left heart syndrome (HLHS) is applied to underdeveloped mitral and/or aortic valves resul...
Patients with symptoms of right heart failure due to severe tricuspid regurgitation following a prior operation on left heart valves present a difficult problem. The outcome of tricuspid surgery in this setting is not well defined. We describe a single-center experience of isolated tricuspid valve su...
The normal appearance of left-sided valves and concurrence of abscesses in extracardiac organs lead us to the conclusion that the left-sided MA had occurred as the result of embolization from the right-sided endocarditis. Antemortem diagnosis of MA remains a challenge and a high index of ...

ventricular, and pulmonary artery waveforms, in addition to the aortic waveform (Figure 9-15). Both right ventricular and pulmonary arterialpulsus alternansmay be seen independent of left-sided pulsus alternans if there is isolated right-heart failure. Isolated atrial alternans has also been de...
Clinical and anatomic features are described in forty-five necropsy patients with left-sided valvular active infective endocarditis. Vegetations in 53 per cent of the patients involved previously anatomically normal valves, and 76 per cent of all patients had previously functionally normal valves. Predis...
Second Heart Sound (S2) S2 is produced by closure of the semilunar valves and is coincident with the T wave on the electrocardiogram (see Fig. 81-1). S2 is best appreciated at the left upper sternal border and varies with the respiratory cycle. During inspiration, the pulmonary v...
at least 200 cases available we observed two significant (p = 1.54 × 10−4, Bonferroni corrected) associations (Methods). The variant rs791274 for PC5 was associated with rheumatic disease of the heart valves, and rs7620927 for PC4 with respiratory symptoms (Supplementary Data24)....
