Insights
Surgical correction of congenital heart defects in children is challenging, especially in newborns. Operations on older children showed good long-term results despite technical difficulties with transposed hearts.
Area of Science:
- Pediatric Surgery
- Congenital Heart Disease
- Cardiovascular Surgery
Background:
- Congenital heart defects necessitate surgical intervention.
- Surgical outcomes can vary significantly with patient age and defect complexity.
Observation:
- Nine pediatric patients underwent surgical correction for heart defects.
- Newborns presented unique challenges due to the delicate nature of cardiac repositioning.
- Elderly children required specialized thoracic frame construction for transposed hearts.
Findings:
- Two newborns with life-incompatible heart defects did not survive.
- Seven older children had successful surgical outcomes.
- Technical difficulties included creating adequate thoracic support for the repositioned heart.
Implications:
- Surgical correction of congenital heart defects is feasible in older children.
- Further research may optimize surgical techniques for complex neonatal cardiac anomalies.
- Successful interventions can lead to good long-term prognoses in pediatric cardiovascular surgery.
Abstract:
9 children aged from 40 hours to 7 years were operated upon. The peculiarity of the surgical intervention in a newborn consists in the difficult arising at the correction of the position of the heart. Both newborns died to the heart defects incompatible with life. The operations carried out upon elder children (7) were successful, the difficulty derived from the necessity to form a thoracic frame over the transposed heart. The late results are good.

02:25Centrosome Duplication
The primary microtubule organizing center (MTOC) in animal cells is the centrosome. A centrosome has two cylindrical centrioles at its core. Each centriole consists of nine sets of three microtubules held together by proteins. The centrioles are positioned at right angles to each other and surrounded by a shapeless protein cloud called the pericentriolar matrix, or pericentriolar material (PCM).

01:17Accessory Structures of the Eye
Optical perception, or vision, is an extraordinary sense dependent on converting light signals received via the ocular organs. These organs, known as eyes, are securely positioned within the bony cavities of the skull, called orbits. The orbits serve a dual purpose: a protective shield for the ocular globes and a stable attachment point for the soft ocular tissues. The eye's external protective mechanisms include the eyelids, which are edged with lashes that act as a barrier against foreign...
01:16Focusing of Light in the Eye
Light rays enter the eye through the cornea, a transparent dome-shaped tissue that is the eye's outermost layer. The cornea bends or refracts, light rays traveling to the pupil. The shape of the cornea determines how much of the light is bent and whether the image will be focused correctly on the retina at the back of the eye. Once the light has passed through both refraction layers, it converges into a single focal point onto a small area. This is where photoreceptors start transforming...
01:22Photoreceptors and Visual Pathways
At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category, whereas...
01:12Visual Agnosia
Visual agnosia is a condition characterized by the inability to recognize visually presented objects despite having normal vision. For instance, a person with visual agnosia can describe the shape and color of an object but cannot identify or name it. This impairment does not affect their visual field, acuity, color vision, brightness discrimination, language, or memory. An example of this condition in a social setting is someone at a dinner party asking for "that silver thing with a round end"...
