Summary
Cor triatriatum dexter (CTD) in dogs often occurs with other congenital heart defects, particularly on the right side. Some dogs with CTD may be asymptomatic or have good outcomes after treatment.
Area of Science:
- Veterinary Cardiology
- Congenital Heart Disease
- Canine Medicine
Background:
- Cor triatriatum dexter (CTD) is a rare congenital cardiac anomaly.
- Understanding its presentation and outcomes in dogs is crucial for diagnosis and management.
Purpose of the Study:
- To describe the signalment, clinical presentation, diagnostic findings, interventions, and outcomes in dogs with CTD.
- To investigate the association of CTD with other congenital cardiac defects.
Main Methods:
- Retrospective review of medical records from 17 client-owned dogs diagnosed with CTD.
- Analysis of signalment, history, physical examination, imaging, concurrent defects, interventions, and outcomes.
Main Results:
- CTD was diagnosed in dogs aged 2-110 months, with 59% under 12 months.
- Peritoneal effusion was the most common presenting complaint (59%).
- CTD was frequently associated with other congenital cardiac anomalies (82%), especially right-sided defects like tricuspid valve dysplasia (53%).
Conclusions:
- Cor triatriatum dexter in dogs is often linked to other right-sided congenital heart anomalies and can be an incidental finding.
- Intervention for obstructive CTD can lead to favorable outcomes.
- Asymptomatic dogs may remain clinically stable into adulthood.

All meta-directing substituents are deactivating groups. These substituents withdraw electrons from the aromatic ring, making the ring less reactive toward electrophilic substitution. For example, the nitration of nitrobenzene is 100,000 times slower than that of benzene because of the deactivating effect of the nitro group. The first step in an electrophilic aromatic substitution is the addition of an electrophile to form a resonance-stabilized carbocation. The energy diagrams for...

Dimensional analysis, also known as the factor label method, is a versatile approach for mathematical operations. The main principle behind this approach is: the units of quantities must be subjected to the same mathematical operations as their associated numbers. This method can be applied to computations ranging from simple unit conversions to more complex and multi-step calculations involving several different quantities and their units.

Reproductive cloning is the process of producing a genetically identical copy—a clone—of an entire organism. While clones can be produced by splitting an early embryo—similar to what happens naturally with identical twins—cloning of adult animals is usually done by a process called somatic cell nuclear transfer (SCNT).
Somatic Cell Nuclear Transfer
In SCNT, an egg cell is taken from an animal and its nucleus is removed, creating an enucleated egg. Then a somatic...

24.1K
Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the...

27.0K
The free energy change for a process may be viewed as a measure of its driving force. A negative value for ΔG represents a driving force for the process in the forward direction, while a positive value represents a driving force for the process in the reverse direction. When ΔGrxn is zero, the forward and reverse driving forces are equal, and the process occurs in both directions at the same rate (the system is at equilibrium).

As early chemists discovered more elements, they realized that various elements could be grouped by their similar chemical behaviors. One such grouping includes lithium (Li), sodium (Na), and potassium (K). All of these elements are shiny, conduct heat and electricity well, and have similar chemical properties. A second grouping includes calcium (Ca), strontium (Sr), and barium (Ba), which also are shiny, good conductors of heat and electricity, and have chemical properties in common. However,...
