In brief
This study of 116 pectus excavatum patients demonstrates that sternal torsion correlates with both chest malformation severity and cardiac compression. Right-sided sternal torsion was significantly associated with greater cardiac compression and reduced tricuspid-to-mitral annulus ratio, suggesting sternal rotation may be an important factor in surgical planning.
Written by the GCMD Library team from the article.
Background/purpose
The role of sternal torsion (ST) in patients with pectus excavatum (PEX) is unknown. We evaluated the relationship between ST and both chest malformation and cardiac compression (CC) indexes.
Methods
We included consecutive patients with PEX who underwent chest computed tomography and cardiac magnetic resonance (CMR) to define surgical candidacy. Malformation indexes included the Haller index (HI), correction index (CI), and ST. CC and the tricuspid to mitral annulus width ratio were evaluated using CMR.
Results
One-hundred and sixteen patients were included, with a mean HI of 5.8 ± 3.6 and a mean CI of 35.8 ± 18.0%. ST was significantly related to malformation indexes, being patients with absence of ST those showing the lowest HI (p = 0.048) and CI (p = 0.002). Right-sided ST was significantly related to the CC classification (p = 0.0001), and the tricuspid/mitral annulus width ratio was significantly lower among these patients (absence 0.98 ± 0.15, left-sided 0.91 ± 0.10, right-sided 0.80 ± 0.15, p
