"Heart sparing" refers to prominent antegrade fetal coronary artery (CA) blood flow readily visualized by color Doppler and is a harbinger of poor outcome in growth restricted fetus, but little is known of the features and presentation of heart sparing in normally grown fetuses. Our objective was...
The v wave was always retrograde without flow reversal. The diastolic wave was always antegrade. The a wave was always retrograde but showed flow reversal in nine of 12 subjects. The systolic:diastolic velocity ratio ranged from 0.9 to 1.5 (mean, 1.1). The minimum:maximum velocity ratio ...
Antegrade ejaculation is achieved by firm closure of the proximal sphincter and a functional distal sphincter. Dripping emission occurs if the distal sphincter is paralyzed, and retrograde ejaculation into the bladder occurs if the proximal sphincter is malfunctioning. Show moreView chapter Chapter Male ...
It provides an excellent exposure of the supraceliac aorta, the option of originating the bypass from several areas of the distal thoracic and supraceliac aorta that is usually spared of atherosclerosis and the bypass is placed in the direction of normal blood flow (antegrade direction). The ...
This growth was not different for patients with a diminutive native ascending aorta or arch or those with a larger native ascending aorta or arch, indicating that compensatory growth of native aortic tissue occurs once unobstructed antegrade aortic flow is established, further giving support to the ...
Antegrade systemic perfusion was reestablished through the perfusion limb of the four-branched prosthetic graft. The anastomosis to the left common carotid artery was carried out first. After the anastomosis was completed, CPB was gradually returned to normal flow, SCP was discontinued, and rewarming...
The complication data indicates that two patients experienced limb ischemia, treated via antegrade perfusion. One patient underwent surgical repair for a femoral perforation. Six patients presented with hematomas. Five patients required blood transfusions due to a significant hemoglobin drop exceeding 2g/...
As the SVR displayed by the monitoring devices (i.e. EV1000 or HemoSphere) is derived from past CVP (not real-time CVP; displays a same value during the antegrade value processing), the current study used calculated SVR (not displayed value from the device) using real-time CVP and ...
What is subintimal dissection? Subintimal dissection/reentry techniques are increasingly being used forcrossing coronary chronic total occlusionsboth antegradely (using a knucle wire or the Bridgepoint system) or retrogradely (using the controlled antegrade and retrograde tracking and dissection, and reve...
After cannulation of the left atrium the hearts were switched to antegrade perfusion (working heart). Perfusate was kept at 37 ºC and bubbled with 95% O2 and 5% CO2. Aortic perfusion pressure was set at 60 mmHg and the left atrium at 10 mmHg at the beginning of each experiment. All...
