Why the study?

Does the type of pre-excitation in Wolff-Parkinson-White syndrome affect interventricular septal motion on echocardiography?

Key Points

To assess interventricular septal motion using echocardiography across different electrocardiographic subgroups of Wolff-Parkinson-White syndrome.
Evaluated 26 consecutive patients with Wolff-Parkinson-White syndrome classified into groups I through IV and 10 normal control subjects.
Recorded echocardiographic motion patterns of the interventricular septum and posterior left ventricular wall during type A and type B pre-excitation.
All 14 patients with type A pre-excitation exhibited normal motion of the interventricular septum and posterior left ventricular wall.
Abnormal septal motion occurred in 11 of 11 patients with type B (Group I) pre-excitation, marked by early systolic posterior motion in 10 patients and a late systolic notch in 8 patients.
One patient with intermittent type B pre-excitation showed normal septal motion that immediately converted to abnormal motion on the first pre-excited beat.

Structured PICO

Does the type of pre-excitation in Wolff-Parkinson-White syndrome affect interventricular septal motion on echocardiography?

Population

26 consecutive patients with Wolff-Parkinson-White (WPW) syndrome and 10 normal subjects.

Intervention

Echocardiographic evaluation of interventricular septal motion

Comparator

Normal subjects and comparison between WPW types (Type A vs Type B)

Outcome

Interventricular septal motion patternssurrogate

Abnormal interventricular septal motion in type B WPW syndrome suggests that altered ventricular depolarization sequence during right ventricular pre-excitation affects septal mechanics.

Discussion

No takes yet. Share an insight, caveat, or question.

Implication

Type B WPW may show abnormal septal motion on echo; leaves open whether pre-excitation pattern alters septal mechanics in larger cohorts.
