PURPOSE: To determine the changes in spirometry of patients with valvular and congenital heart disease before and after open heart surgery.

METHODS: Eligible subjects were asked to sign an informed consent. Spirometry were performed preoperative and post operatively at 1 month, 3 months and 6 months post surgery. The following parameters were evaluated: forced vital capacity (FVC), forced expiratory volume in the first second (FEV1) and FEV1/FVC. Factors that could affect post operative PFT results of patients were also determined in the study.

RESULTS: FVC was significantly reduced in the preoperative period in all patients. There was a tendency of the values to slightly improve one month after surgery. There was also significant improvement of lung function 3 months after. FEV1 was significantly reduced in all patients before surgery. At the first month post surgery, there was a significant improvement of lung function and even much improved after 3 months post surgery. The FEV1/FVC ratio was normal in all subjects.

CONCLUSIONS: This study concludes that spirometry was impaired in patients with rheumatic heart disease and congenital heart disease and deteriorates immediately after surgery but data showed that it improve one month after surgery.

CLINICAL IMPLICATIONS: Spirometry is recommended as a tool to evaluate the respiratory reserves in patients who will undergo cardiac surgery. The use of these parameters were found to be sensitive in predicting perioperative and postoperative morbidity.
