The relationship of pulmonary artery wedge pressure to the posterior aortic wall echocardiogram in patients free of obstructive mitral valve disease

The gross features of the aortic valve apparatus, consisting of three semilunar leaflets, three interleaflet triangles, three commissures, and the aortic wall, are discussed both in terms of normal and pathological anatomy. The concept of aortic annulus and the relationship of the aortic valve with the coronary arteries, the membranous septum, and conduction system and the mitral valve are addressed. When dealing with pathology, the chapter focuses on the main distinctive features of aortic valve stenosis and aortic valve incompetence. Regarding the former, the abnormalities reside in the cusps, either two or three in number, with cusp thickening, and calcification with or without commissural fusion (thus distinguishing senile and chronic rheumatic valve disease); in the latter, the gross changes can affect either the cusps (infective endocarditis with tissue perforation/laceration and rheumatic valve disease with tissue retraction) or the aortic wall (ascending aorta aneurysm either inflammatory or degenerative). The distinctive gross abnormalities in the various conditions are illustrated.

Abstract Purpose: The aims of the study were to determine the factors associated with PH among patients with mitral valve disease, and the similarities and differences in the subgroups of mitral stenosis (MS) and mitral regurgitation (MR). Methods: Patients with isolated moderate to severe organic mitral valve disease were prospectively enrolled. Pulmonary hypertension (PH) was defined echocardiographically as pulmonary artery systolic pressure > 50 mmHg. Patients with MS who had mitral valve area > 1.5 cm2 and patients with MR who had effective regurgitant orifice area < 20 mm2 were excluded. Results: There were 318 patients (mean age 54.3 ± 15.5 years, 57.6% female, 66.7% MR). PH was present in 119 (37.4%) patients (48.1% and 31.8% in MS and MR, respectively). Severe mitral valve disease was reported in 245 (77.0%) patients. Left atrial (LA) diameter and pulmonary artery pressure were significantly higher in patients with MS. Dyspnea, LA volume index, significant tricuspid and pulmonary regurgitation, severe mitral valve disease and the presence of MS were independently associated with PH. Among patients with MS, LA volume index and severe disease were independently associated with PH. Significant tricuspid and pulmonary regurgitation, LA volume index and severe disease were independently associated with PH in patients with MR. Conclusions: PH is common in patients with mitral valve disease. LA volume index and severe disease were, in common, independently associated with PH in patients with mitral valve disease and in the subgroups of MS and MR.
