Comparisons of mechanical versus phase-array intracardiac echocardiography-assisted transseptal puncture in patients with dilated left atrium undergoing percutaneous transvenous mitral commissurotomy.
J Chin Med Assoc. 2010 Sep; 73(9):471-6.JC

Abstract

BACKGROUND

Percutaneous transvenous mitral commissurotomy (PTMC) is an effective treatment for mitral stenosis, but transseptal puncture carries a certain risk of complications. Our previous report has shown the effectiveness of phase-array intracardiac echocardiography (ICE)-guided transseptal puncture in patients with dilated left atrium undergoing PTMC. However, there are few reports comparing the new-generation mechanical versus phase-array ICE-guided transseptal puncture in PTMC.

METHODS

Between March 2007 and March 2008, 6 consecutive patients with symptomatic mitral stenosis with dilated left atrium (range, 4.1-6.1 cm) underwent transseptal puncture by mechanical ICE guidance in PTMC by the same experienced operator. The procedural, echocardiographic and clinical results were retrospectively retrieved and analyzed. In addition, phase-array ICE-guided transseptal cases (n = 7), which included consecutive cases from May to December 2008, were compared.

RESULTS

All 6 patients could have fossa ovalis visualized by ICE, and none of them had false transseptal puncture. Mechanical ICE provided a panoramic wider view of the interatrium septum, and offered better knowledge of the needle's geographic contact to the fossa ovalis than did the phase-array system. The fluoroscopic time of PTMC in the mechanical ICE-guided group (37 ± 9 minutes, n = 6) was similar (p = 0.465) to that of phase-array guidance (31 ± 15 minutes, n = 7).

CONCLUSION

Mechanical ICE is effective in guiding transseptal puncture in PTMC.
