Atrial septal defect--echocardiographic assessment before and after surgical repair.

Acta Médica Portuguesa, 1979
Twenty-two patients with atrial septal defect (ostium secundum type and sinus venosus) were studied by echocardiography before and after surgery. The sizes of the various heart chambers - right and left ventricles, left atrium and aortic root - and the ...

Automatic segmentation of the left ventricle cavity and myocardium in MRI data [PDF]

, 2006
A novel approach for the automatic segmentation has been developed to extract the epi-cardium and endo-cardium boundaries of the left ventricle (lv) of the heart. The developed segmentation scheme takes multi-slice and multi-phase magnetic resonance (MR)

Light Switchable Ionic Conductivity of Arylazopyrazole Modified Polysiloxanes

Advanced Materials Technologies, EarlyView.
We present a polysiloxane functionalized with a novel arylazopyrazole dye that undergoes reversible photoisomerization. Upon lithium bis(trifluoromethanesulfonyl)imide addition and UV irradiation, the polymer exhibits a shift in tan(d) toward higher frequencies and enhanced ionic conductivity.

Predominance of Intrinsic Mechanism of Resting Heart Rate Control and Preserved Baroreflex Sensitivity in Professional Cyclists after Competitive Training. [PDF]

PLoS ONE, 2016
Different season trainings may influence autonomic and non-autonomic cardiac control of heart rate and provokes specific adaptations on heart's structure in athletes. We investigated the influence of transition training (TT) and competitive training (CT)

Design and Utilization of Stable Hydrofluoroolefin‐Based Trifluoropropynyl Surrogate for Sonogashira Coupling

Advanced Synthesis &Catalysis, EarlyView.
A novel methodology for the construction of aromatic and heteroaromatic trifluoropropynyl derivatives has been developed. The new protocol is based on a tandem Sonogashira cross‐coupling reaction between a bench‐stable trifluoropropynyl carbinol reagent, generated from the commercially available and inexpensive hydrofluoroolefin‐1234yf gas, and (hetero)

Application of Foley balloon catheter in palliative surgery for pulmonary atresia with an intact ventricular septem, with additional cases of pulmonary atresia with ventricular septal defect and tetralogy of Fallot

BMC Cardiovascular Disorders, 2023
Background Pulmonary atresia and tetralogy of Fallot can require palliative surgery in the neonatal period due to severe hypoxia; however, limitations of established techniques include high failure rate and need for cardiopulmonary bypass.
