“…6 Given the later age at diagnosis, older adult patients often exhibit chronic changes in LV hemodynamics (such as restrictive physiology). 13,20 Previously, there has been some debate about closing those defects in patients with marked LV restriction or signs of abnormal filling hemodynamics. Most of the controversy for this approach stems from a small number of case studies discussing patients with complications following closure.…”

“…The median septal defect size as measured by static balloon sizing under fluoroscopy and intracardiac echocardiography was 22 mm (14-29) and 20 mm (12.5-28.5), respectively. The median ASO size device implanted was 20 mm ( [14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30]. No fenestrated devices were implanted.…”

“…This study is focused only on acute changes, even if changes in size of both ventricles are defined as an early event 17 nearly 90% of those changes ensued within one month from shunt closure and 50% occurred within 24 hours 26 a more complete study with long‐term control and stratification of remodeling based on age at time of intervention and ASD dimensions is necessary. In our study cardiac output was calculated by 2D echocardiography, which is less reliable than other reference methods such us magnetic resonance imaging.…”

To evaluate acute change of right and left ventricle after percutaneous closure of isolated atrial septal defect (ASD) 21 adult patients (13 F; 8 M) aged 28 ± 9.5 range 18-49 years have been examined by echocardiography before and 24 hours after percutaneous closure of ASD. Twenty-one normal adult subjects, as control group were included. A MyLab25 echo machine equipped with a multifrequency 2.5-3.5 MHz transducer was used. Offline computer-based analysis for strain and SR were performed using XStrain software based on a feature tracking algorithm. All patients had ASD OS2 with right ventricular dilatation and diastolic areas were larger than in controls: P = 0.0158. Global right ventricular longitudinal strain was higher P = 0.0438. Twenty-four hours after ASD closure, right ventricular diastolic and systolic areas were significantly reduced. Right ventricular global longitudinal systolic strain decreased: P = 0.00016, as well as global right ventricular longitudinal SR -1.56/sec ± 0.57 vs. -1.28/sec ± 0.31, P = 0.02646. At the mean time left ventricular end diastolic volume and left ventricular cardiac output measured by two-dimensional echocardiography both increased significantly P = 0.002145 and 0.013409. Global circumferential strain at mitral level augmented significantly -20.3%± 4.64 vs. -25.39%± 5.22, P = 0.00003. Longitudinal strain of the right ventricle works as indicator of right ventricular function dependent on loading conditions while SR seems to be less dependent on it. Circumferential strain could be used as an indicator of left ventricular response to normalized loading conditions.

“…A number of editorials addressing echo-Doppler related subjects were contributed by the author [17][18][19][20][21]; most of these are prepared at the request of the respective chief editors. These Based on these data, it was concluded that the long-term results of BPV are excellent and that BPV is the management of option in the treatment of valvar PS; however, our study raises concern regarding development of PI at long-term follow-up [16].…”

The author’s contribution up to 1990 was reviewed in part I and the echo contributions from 1991 to 2020 will be reviewed in part II. These include defining the relationship between the quantity of shunt across the atrial septal defect (ASD) and the diameter of ASD by echo and angio on the one side and the stretched diameter of the ASD on the other; echocardiographic assessment of balloon-stretched diameter of secundum ASDs; development of echocardiographic predictors of accomplishment of percutaneous closure of ASDs with the buttoned device, highlighting limitations of echocardiography in comprehensive assessment of mixed type of total anomalous pulmonary venous connection; description of follow-up echocardiographic results of transcatheter closure of ASD with buttoned device; review of ultrasound studies; depiction of collaborative echocardiographic and Doppler studies; echocardiographic appraisal of the outcome of balloon pulmonary valvuloplasty; editorials; ventricular septal aneurysm causing pulmonary outflow tract obstruction in the morphologic left ventricle in corrected transposition of the great arteries; dependability of echocardiographic assessment of angiographic minimal diameter of the ductus; occurrence of supravalvular pulmonary artery stenosis after a Nuss procedure; echocardiographic assessment of neonates who were suspected of having heart disease; role of echocardiographic studies in the appraisal of patent ductus arteriosus in the premature babies; and the role of pressure recovery in explaining differences between simultaneously measured Doppler and cardiac catheterization pressure gradients across outflow tract stenotic lesions.
