Pulmonary veins: an important side window into ventricular function
Routine echocardiographic evaluation of left ventricular (LV) diastolic function includes measurement of mitral flow velocities, mitral annular velocities, and left atrial (LA) volume. Based on patterns of mitral filling, diastolic dysfunction is traditionally quantified as mild (Grade I), moderate (Grade II), and severe (Grade III). A problem with defining Grade II is that this mitral filling ...
متن کاملLeft ventricular function in varicose veins.
Left ventricular function (LVF) was evaluated noninvasively by recording systolic time intervals (STIs) in 25 patients suffering from varicose veins (VV) of lower limbs and compared with 25 age--sex matched controls. STI was measured from simultaneous recordings of electrocardiogram (ECG), carotid arterial pulse (CAP) and phonocardiogram (PCG). The left ventricular ejection time (LVET) was sign...
متن کاملFeedback Modulation: A Window into Cortical Function
A recent study demonstrates involvement of primary motor cortex in task-dependent modulation of rapid feedback responses; cortical neurons resolve locally ambiguous sensory information, producing sophisticated responses to disturbances.
متن کاملPulmonary vascular wall stiffness: An important contributor to the increased right ventricular afterload with pulmonary hypertension
Pulmonary hypertension (PH) is associated with structural and mechanical changes in the pulmonary vascular bed that increase right ventricular (RV) afterload. These changes, characterized by narrowing and stiffening, occur in both proximal and distal pulmonary arteries (PAs). An important consequence of arterial narrowing is increased pulmonary vascular resistance (PVR). Arterial stiffening, wh...
متن کاملTotal drainage of pulmonary veins into the right atrium.
Anomalies of the pulmonary venous return are uncommon, particularly malformations with total drainage of the pulmonary veins directly into the right atrium. Brody (1942) reviewed the literature on anomalous pulmonary venous drainage, dealing with 106 cases, including four personal ones. Further necropsy reports have since been presented by Vass and Mack (1949) and Smith (1951), the latter also ...
