Nettet13. apr. 2024 · Pulmonary hypertension (PH) is classified in five groups: Group 1 is PAH with several etiologies including idiopathic, heritable PAH, collagen vascular disease, congenital heart disease, HIV, drugs, or portopulmonary hypertension. Group 2 is PH owing to left heart disease. Group 3 is PH owing to lung disease. NettetFetal valvuloplasty (FV) has been proposed to improve left heart hemodynamics and maintain biventricular (BV) circulation. The aim of this study was to assess FV efficacy by comparing survival and postnatal circulation between fetuses that …

NettetThe transplanted heart markedly improves cardiac hemodynamics, but there may be a slightly diminished maximal cardiac output during exercise secondary to denervation, limited atrial function, decreased myocardial compliance from rejection or ischemic injury, and donor-recipient size mismatch. NettetDiastolic dysfunction is the cardinal component for the diagnosis of heart failure with preserved left ventricular ejection fraction (LVEF). It has been suggested that patients who have heart failure with preserved LVEF tend to be …
