Summary
A rare Gerbode defect, a left ventricle to right atrium communication, is presented. This specific case involves a small ventricular septal defect covered by an abnormal tricuspid valve leaflet, creating an aneurysm and directing blood flow into the right atrium.
Area of Science:
- Cardiology
- Congenital Heart Disease
- Cardiac Surgery
Background:
- Gerbode defects represent abnormal communications between the left ventricle and right atrium.
- Type I defects are direct and acquired, while Type II defects are indirect and congenital, involving a ventricular septal defect (VSD) and tricuspid valve abnormality.
Observation:
- This report details an exceptionally rare variant of a Gerbode defect.
- A small perimembranous VSD was observed to be entirely obscured by an unusually elongated, sail-like anterior tricuspid valve leaflet.
Findings:
- The elongated tricuspid leaflet formed an aneurysm, effectively redirecting the shunt from the left ventricle directly into the right atrium.
- This anatomical configuration represents a unique mechanism for left ventricle-to-right atrium shunting.
Implications:
- Understanding this rare variant is crucial for accurate diagnosis and surgical planning in complex congenital heart disease.
- This case highlights the diverse anatomical presentations of Gerbode defects and the importance of detailed echocardiographic and surgical evaluation.

Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

Since the discovery of the two BER pathways, there has been a debate about how a cell chooses one pathway over the other and the factors determining this selection. Numerous in vitro experiments have pointed out multiple determinants for the sub-pathway selection. These are:

Gregor Mendel's work (1822 - 1884) was primarily focused on pea plants. Through his initial experiments, he determined that every gene in a diploid cell has two variants called alleles inherited from each parent. He suggested that amongst these two alleles, one allele is dominant in character and the other recessive. The combination of alleles determines the phenotype of a gene in an organism.

01:29Nondisjunction
81.7K
During meiosis, chromosomes occasionally separate improperly. This occurs due to failure of homologous chromosome separation during meiosis I or failed sister chromatid separation during meiosis II. In some species, notably plants, nondisjunction can result in an organism with an entire additional set of chromosomes, which is called polyploidy. In humans, nondisjunction can occur during male or female gametogenesis and the resulting gametes possess one too many or one too few chromosomes.

4.8K
Nondisjunction is the failure of homologous chromosomes or sister chromatids to separate correctly and move to the opposite poles of the cells. This produces daughter cells with abnormal chromosome numbers. Nondisjunction is common during anaphase I or anaphase II of meiosis. Mutations in synaptonemal complex proteins that attach homologous chromosomes increase the chances of nondisjunction in anaphase I of meiosis I. In contrast, mutations in topoisomerases and condensins that hold...
