Very-long-term outcomes of mechanical valves in mitral position focusing on valve-related complications.

ABSTRACT:

Objectives

This study aimed to examine very-long-term outcomes of a mechanical valve at the mitral position.

Methods

This study included all patients who underwent mitral valve replacement (MVR) using a mechanical valve including urgent operation at the Department of Cardiovascular Surgery, Hyogo Brain and Heart Center, Himeji, from January 1987 to December 2015.

Results

Five hundred and eighty-three patients (277 men [47.51%]; age, 61 [54-67] years) were included in this study. The implanted valve models were as follows: SJM, 221 (37.91%); ATS, 35 (6.00%); On-X, 68 (11.66%); and Carbomedics 194, (33.28%).The median clinical follow-up duration was 13.3 (7.4-19.6) years. The survival rates at 10, 15, 20 and 25 years were 81.42%, 69.27%, 56.34% and 45.03%, respectively.
