The effectiveness of mitral valve surgery in patients with open heart surgery in Samut Sakhon hospital

Abstract

The mitral valve surgery consists of mitral valve repair and mitral valve replacement. The option depends on the pathology of mitral valve disease. The primary outcome were surgical outcome, early mortality in 30 days and complication in mitral valve surgery. The secondary outcome were the comparison of the result of mitral valve surgery between mitral valve repair and mitral valve replacement, postoperative results and complications.

In this descriptive study, the studied group consisted of 59 patients undergoing mitral valve repair and 64 patients undergoing mitral valve replacement who receive mitral valve surgery (Total 120 patients) in Samut Sakhon hospital. The patients were recruited from the medical record since 1 January 2019 to 30 April 2022. The statistics used for analysis of the data were frequency, percentage, mean, standard deviation, Chi-square test and Independent sample T-test.

There were 7 (5.70%) patients of mitral valve surgery with death in 30 days, There was no significant difference between 3 (5.08%) patients of mitral valve repair and 4 (6.25%) patients of mitral valve replacement. There were 11 (8.95%) patients with acute kidney injury (AKI) and required hemodialysis 1 (0.80%) patient. The postoperative complication consisted of low cardiac output syndrome 8 (6.50%) patients, postoperative stroke 3 (2.40%) patients, postoperative VF/VT 1 (0.80%) patient and postoperative heart block 1 (0.80%) patient.

The effectiveness of mitral valve surgery can be safely performed in patients with mitral valve disease with low postoperative morbidity and mortality rates. The decision to operate the patients depends on the patient’s condition, surgical finding and experience before surgery.
