[Postoperative evaluation of Carpentier's mitral rings]

Area of Science:

• Cardiology
• Cardiovascular Surgery

Background:

• Mitral valve regurgitation is a common cardiac condition.
• The Carpentier ring is a surgical device used to treat mitral valve insufficiency.

Purpose of the Study:

• To evaluate the effectiveness of the Carpentier ring in restoring mitral valve function.
• To correlate pre- and post-operative clinical and radiographic findings with angiocardiographic results.

Main Methods:

• Study included 38 patients who underwent mitral valve surgery with Carpentier ring insertion.
• Pre- and post-operative mitral murmurs were graded.
• Radiographic heart and left atrial size were assessed.
• Pre- and post-operative angiocardiographic studies were performed to evaluate mitral regurgitation.

Main Results:

• Only 3 patients (7.8%) experienced significant pulmonary artery systolic pressure elevation and severe angiographic regurgitation, requiring reoperation.
• 60.52% of patients had no or grade I murmurs post-operatively.
• 76.32% of patients showed no mitral regurgitation on angiocardiography.
• No significant correlation was found between murmur intensity and the grade of angiographic mitral regurgitation.

Conclusions:

• The Carpentier ring effectively restores normal mitral valve function in the majority of patients.
• Angiocardiographic results following Carpentier ring implantation are generally favorable.
• The device demonstrates good outcomes in treating mitral valve insufficiency.
