Stereoisomerism

Stereoisomerism

Isomerism in Complexes
Isomers are different chemical species that have the same chemical formula.
Transition metal complexes often exist as geometric isomers, in which the same atoms are connected through the same types of bonds but with differences in their orientation in space. Coordination complexes with two different ligands in the cis and trans positions from a ligand of interest form isomers. For example, the octahedral [Co(NH3)4Cl2]+ ion has two isomers (Figure 1) In the cis...

Summary

Complex atrial baffling procedures were successfully used for biventricular repair in patients with left isomerism and right-hand ventricular topology. Understanding venous connections and atrial anatomy via 3D printing was key to this surgical success.

Area of Science:

Cardiology
Pediatric Cardiac Surgery
Congenital Heart Disease

Background:

Left isomerism presents complex congenital heart defects.
Ventricular topology, specifically right-hand vs. left-handed, influences surgical strategy.
Accurate anatomical understanding is crucial for successful surgical repair.

Purpose of the Study:

To describe complex atrial baffling techniques.
To detail the application of these techniques in left isomerism with right-hand ventricular topology.
To highlight the role of advanced imaging in achieving successful biventricular repair.

Main Methods:

Utilized complex atrial baffling procedures.
Employed 3D printing to visualize internal atrial anatomy and venous connections.
Performed biventricular repair in patients with specific isomerism and topology.

Main Results:

Successful biventricular repair was achieved.
Detailed understanding of venous connections and atrial anatomy facilitated the procedure.
Complex baffling techniques were effective in this specific patient cohort.

Conclusions:

Complex atrial baffling is a viable strategy for biventricular repair in left isomerism with right-hand ventricular topology.
3D printing enhances surgical planning by clarifying complex cardiac anatomy.
Successful outcomes depend on precise anatomical understanding and tailored surgical approaches.
