Transseptal puncture is crucial for mitral balloon valvuloplasty. Precise puncture location, guided by imaging, is key for safety and efficacy in patients with valvular heart disease.

Area of Science:

  • Interventional Cardiology
  • Cardiac Catheterization
  • Valvular Heart Disease

Background:

  • Transseptal puncture has resurged due to therapeutic catheterizations like mitral balloon valvuloplasty.
  • Optimal puncture site varies and may not be the fossa ovalis, which can be displaced or inaccessible.
  • Valvular heart disease causes dynamic changes in atrial and septal anatomy.

Purpose of the Study:

  • To evaluate the safety and efficacy of image-guided transseptal puncture in patients undergoing procedures for valvular heart disease.
  • To highlight the importance of precise septal puncture location tailored to individual patient anatomy.

Main Methods:

  • Utilized precatheterization echocardiography and radiological techniques for precise, localized transseptal puncture.
  • Applied these techniques in a cohort of 597 patients with various forms of valvular heart disease.

Main Results:

  • Achieved successful transseptal punctures in all 597 patients.
  • Reported a low procedural morbidity rate of 1.8%.
  • No procedure-related deaths were observed.

Conclusions:

  • Image-guided transseptal puncture is a safe and effective technique for patients with valvular heart disease.
  • Precatheterization imaging allows for precise localization of the septal puncture site, accommodating anatomical variations.
  • This approach minimizes complications and ensures successful therapeutic catheterizations.
