Indomethacin is a potent agent in the treatment of premature labor, but its use has been limited because concern about constrictive effects on fetal ductus arteriosus. To study these we used serial echocardiography 13 pregnant women labor who received indomethacin according to three different dose schedules, ranging from 100 175 mg per day, for maximum 72 hours. The gestational ages fetuses ranged 26.5 31.0 weeks. detection ductal constriction 7 14 by led discontinuation indomethacin. Three...
Pulmonary hypertension may occur in the fetus presence of constriction ductus arteriosus. The feasibility detection and quantitation fetal ductal by Doppler echocardiography was assessed an animal preparation which created lamb with a variable ligature causing varying degrees pulmonary (fetal arterial systolic pressure 57 to 97 mm Hg gradient 9 42 Hg). Comparison blinded, continuous-wave peak velocity (V) measurements modified Bernoulli assumption (gradient = 4V2) compared well direct...
Abstract The aim of this study was to examine the fetal hemodynamic effects terbutaline treatment and premature labor. Image‐directed pulsed continuous wave Doppler ultrasound studies, using 3.3‐MHz 5‐MHz transducers (GE PASII ATL echocardiographic machines), were used assess cardiac blood velocities in three groups pregnancies matched for menstrual age (MA). Group 1: 13 normal pregnancies, mean MA 31 weeks. 2: 7 women labor prior tocolytic therapy, 32 3: 8 treated with terbutaline, average...
The aim of this study is to determine the prevalence coronary artery ectasia and its relationship atheromatous changes in participants undergoing computed tomography angiography.Coronary occasionally encountered on conventional angiography considered a manifestation atherosclerosis.Four hundred consecutive participants, 300 men (mean age 56 years) who underwent were evaluated. Coronary was defined as an arterial segment with diameter at least 1.5 times adjacent normal artery. location well...
Patients with acute ST-elevation myocardial infarction (STEMI) and increased platelet count treated by fibrinolysis have worse outcomes.The aim of this study was to test the hypothesis that blood at admission in patients STEMI primary percutaneous coronary intervention affects flow, perfusion recovery left ventricular systolic function.A total 174 presenting anterior were included divided into subgroups <200 K, 200-300 300-400 K >400 K. Evaluation artery flow blush grade performed according...
Myocardial stunning is responsible for partially reversible left ventricular (LV) systolic dysfunction after successful primary percutaneous coronary intervention (PPCI) in patients with acute ST-elevation myocardial infarction (STEMI).To test the hypothesis that early blood flow (CBF) to LV function ratios, as an equivalent index (SI), predict recovery of PPCI STEMI.Twenty-four anterior STEMI who had were evaluated and compared 96 control subjects. Transthoracic echocardiography measurement...
Normal left anterior descending (LAD) coronary artery as determined by angiography is considered not only to reflect normal but also correlate with anatomy and function. However, subjects who undergo may differ from those do need have invasive evaluation even if their functional noninvasive studies like dobutamine stress echocardiography (DSE) were normal.LAD velocities in DSE are equal.A total of 244 evaluated, 78 had LAD 166 DSE. All Doppler sampling transthoracic echocardiography.Velocity...
Hypcrtrophy of the left ventricle may be associated with altered ventricular filling dynamics. To test whether isometric and isotonic training affect differently at rest during stress, 38 males, 13 long distance runners, eight weight-lifters, hypertensive patients nine age-matched healthy male controls a mean age 30 ± 7 years, were studied before after 90 s 50% maximal handgrip force. Left Doppler parameters compared in four groups while they resting stress testing, results assessed relation...
Myocardial bridging (MB) is defined as an intramural segment of a coronary artery that normally courses epicardially. MB usually benign condition; however, some cases resulting in myocardial ischaemia, infarction and sudden death have been reported. We describe case related to young healthy woman with no risk factors for disease. The bridge was demonstrated detail by CT angiography using multiplanar reconstruction three-dimensional volume-rendered techniques.
In the presence of severe stenosis, coronary artery flow may be reduced at rest. Recent advances in echocardiography have made non-invasive sampling velocities left anterior descending (LAD) possible. The aim our study was to evaluate feasibility and capability transthoracic Doppler detect stenosis LAD. population consisted 42 subjects with suspected disease scheduled for angiography. All had complete LAD velocities. Quantitative angiography performed within 24 hours echocardiogram....
<b><i>Background:</i></b> Phototherapy has been reported to alter blood flow various tissues. We hypothesized that during phototherapy the coronary will decrease because of a ‘steal effect' periphery. <b><i>Objectives:</i></b> To evaluate effects on in healthy, jaundiced, term neonates. <b><i>Methods:</i></b> Flow velocity [peak diastolic (Vd)] and measures [diastolic time integral (TVId) index (FI)] left main (LM)...

Abstract While bicuspid aortic valve (BAV) is a common congenital cardiac anomaly, quadricuspid (QAV) rare. The usual three‐leaflet characterized by engineering advantages with superior long‐term performance, and thus, degenerative changes significant functional deterioration appear at advanced age. Aim: Evaluation of similarities, differences between QAV BAV. Methods: Screening 19 000 consecutive echocardiographic studies was performed. Results: BAV reported in 131 subjects prevalence 0.7%,...
Purpose: Idiopathic pulmonary arterial hypertension (IPAH) prognosis depends on the capability of right ventricle (RV) to preserve its function in face increased afterload.We hypothesize that, as for left ventricle, intra-ventricular (IVD) dyssynchrony may have a negative effect overloaded RV.The aim study was assess IVD by incorporating activation times longitudinal deformation across all RV segments, representing major contribution chamber contraction.Methods: Eighty patients with IPAH (52...
The treatment of choice in acute ST-elevation myocardial infarction (STEMI) is primary percutaneous coronary intervention (PPCI). Although, thrombolysis (TIMI) and blush grade (MBG) measures provide semi-quantitative flow evaluation after PPCI, serial quantitative volumetric still lacking.Serial assessment left anterior descending (LAD) artery patients with (MI), immediately 48 h later pre-discharge compare findings optimal suboptimal PPCI result their relation to ventricular ejection...
