Summary

This study explored less invasive closed mitral commissurotomy (CMC) techniques using limited thoracotomy and port access with transesophageal echocardiography (TEE). Both methods proved feasible and safe, offering alternatives to traditional surgery.

Area of Science:

  • Cardiovascular Surgery
  • Minimally Invasive Cardiac Surgery
  • Echocardiography

Background:

  • Closed mitral commissurotomy (CMC) is being re-evaluated for less invasive approaches.
  • Transesophageal echocardiography (TEE) aids in guiding valvular surgery.

Purpose of the Study:

  • To investigate the feasibility of less invasive CMC using port access or limited thoracotomy guided by TEE.
  • To assess the efficacy and safety of these novel techniques.

Main Methods:

  • 42 patients underwent less invasive CMC between August 1996 and April 1998.
  • Procedures included limited thoracotomy (12-16 cm), mini thoracotomy (7-8 cm), or port access with TEE guidance.
  • Preoperative mitral valve area and gradient were measured; TEE provided intraoperative anatomical and functional data.

Main Results:

  • Successful commissurotomy in all patients.
  • Postoperative mitral valve area increased significantly (1.19 to 2.37 cm²), and gradient decreased (14.8 to 5.3 mmHg).
  • No complications were reported; patients experienced short ICU stays and hospitalizations.

Conclusions:

  • Limited thoracotomy offers less detrimental structural effects.
  • Port access with TEE guidance for CMC is a less invasive, potentially cost-effective alternative to percutaneous balloon mitral valvotomy.
