Relation of left ventricular isovolumic relaxation time and incoordination to transmitral Doppler filling patterns.
To investigate factors during isovolumic relaxation that determine Doppler filling patterns in patients with left ventricular disease, and thus to identify the underlying mechanisms. ⋯ The main factors influencing the A/E ratio in patients with left ventricular disease are two distinct properties of isovolumic relaxation--namely the duration and the extent of incoordinate wall motion. Filling pressure and RR interval are not significant independent determinants, but act only through an effect upon isovolumic relaxation time. Age is an important influence in normal people, but this effect is attenuated in left ventricular hypertrophy and lost in ischaemic ventricular disease.

Case ReportsPulmonary artery rupture in pregnancy complicating patent ductus arteriosus.
Fatal haemopericardium in a 27 year old pregnant woman was caused by rupture of a dissecting aneurysm of the pulmonary artery. She had an uncorrected patent ductus arteriosus and severe pulmonary hypertension. The wall of the pulmonary artery showed atherosclerosis and cystic medionecrosis.
