Hemodynamic effects of left pulmonary artery stenosis after superior cavopulmonary connection: a patient-specific multiscale modeling study.
OBJECTIVE Currently, no quantitative guidelines have been established for treatment of left pulmonary artery (LPA) stenosis. This study aims to quantify the effects of LPA stenosis on postoperative hemodynamics for single-ventricle patients undergoing stage II superior cavopulmonary connection (SCPC) surgery, using a multiscale computational approach. METHODS Image data from 6 patients were s...
متن کاملHemodynamic effects of intravenous sodium nitroprusside in the conscious dog.
The hemodynamic effects of 7 min i.v. sodium nitroprusside (NP) were studied in conscious dogs previously instrumented for measurement of arterial pressure, cardiac output, regional blood flow distribution, left ventricular (LV) pressure, and internal dimensions. Nitroprusside, 25 microgram/kg/min, reduced mean arterial pressure by 23 +/- 3%. Cardiac output increased initially by 39 +/- 7% and ...
متن کاملNeurohormonal activation late after cavopulmonary connection.
OBJECTIVE To determine whether patients with cavopulmonary connection have higher levels of vasoactive/water-salt regulating hormones and if so, whether hormone levels are related to postoperative haemodynamics and postoperative follow up. DESIGN Cross sectional study. SETTING University hospital. PATIENTS 20 patients (New York Heart Association functional class I-II), mean age 11 years (...
متن کاملHemodynamic and metabolic effects of sodium nitroprusside on the performance and metabolism of regional ischemic myocardium;.
To assess the effects of sodium nitroprusside (5-10 mug/min) on total and regional cardiac performance, energetics, and lactate metabolism during acute ischemia, studies were performed in 21 open-chest dogs. For studies of regional function and metabolism, length gauges were sutured to the epicardial surface and an epicardial vein adjacent to the artery to be occluded was cannulated. Following ...
متن کاملHemodynamic effects of preload and sodium nitroprusside in patients subjected to coronary bypass surgery.
To differentiate between the hemodynamic effects of afterload reduction produced by sodium nitroprusside (NP) and the effects of preload, left ventricular function curves were constructed during and without NP infusion at the same, normal left ventricular filling pressure (LVFP) levels for 20 patients 8 hours after coronary bypass grafting and for 10 of these patients preoperatively. Preoperati...
