Introduction: Complex electrophysiologic (EP) procedures are time consuming and open
to complications. Accurate and rapid recognition of cardiac pathologies is essential before,
during, and immediately after such procedures. In this study, we aimed to compare hand-held
echocardiography (HHE) with standard echocardiography (SE) to determine whether HHE can
be used as a practical and reliable diagnostic tool during such procedures.
Methods: One hundred consecutive patients undergoing complex EP procedures and catheter
ablation were included in the study. All patients were evaluated with SE or HHE in terms of
main cardiac pathologies at the beginning and immediately after the procedure. The diagnostic
accuracy and evaluation time of both methods were compared at the beginning and after the
procedure. The agreement between both methods was calculated.
Results: At the beginning and after the procedure, opening and evaluation times with HHE were
significantly shorter than with SE (P<0.001 for all). There was significant agreement between
the two methods in the diagnosis of cardiac pathologies (Agreement was 95% for minimal
mild aortic regurgitation (AR), 99% for moderate/ severe AR, 93% for minimal/ mild mitral
regurgitation (MR), 95% for moderate/ severe MR, 100% for pericardial effusion, and 100% for
left ventricular thrombus at the beginning of the procedure).
Conclusion: With the use of HHE during complex EP procedures, cardiac pathologies can be
diagnosed with similar accuracy as SE. In addition, HHE has a significant advantage over SE in
terms of time to diagnosis.
