PG - e29038 LID - 10.5812/cardiovascmed.29038 [doi] LID - e29038 AB - BACKGROUND: Patient-prosthesis mismatch (PPM) after aortic valve replacement (AVR) is the subject of continuing debate in the cardiac surgery field. OBJECTIVES: The aim of this study was to evaluate the frequency and severity of patient-prosthesis mismatch (PPM) and the functional status of patients undergoing aortic valve replacement (AVR) using a CarboMedics prosthesis in the mid-term follow up. PATIENTS AND METHODS: We retrospectively studied 66 consecutive patients who were referred to AVR with a CarboMedics prosthesis at the Rajaie cardiovascular medical and research center, a university referral hospital in Tehran, Iran. The severity of PPM as well as clinical and echocardiographic parameters and the patients' New York heat association (NYHA) functional classification status, operative data and postoperative complications, and mortality in a mid-term (4 - 5 months) follow up period was assessed. Severe PPM was defined as the effective orifice area (EOA) indexed to the patient's body surface area (BSA) < 0.65 cm(2)/m(2) and moderate PPM was defined as the indexed effective orifice area (IEOA) between 0.65 and 0.85 cm(2)/m(2). RESULTS: Of the 66 studied patients, 39 were male and 27 were female. The mean age of the patients was 43 +/- 17 with a range of 6 - 76 years. Implanted sizes of the CarboMedics AV prosthesis in 22 patients were 19 and 21 mm, and in 44 patients were 23 and 25 mm. Eleven patients had moderate PPM (IEOA < 0.85 cm(2)/m(2)) and 55 of them did not have PPM (IEOA >/= 0.85 cm(2)/m(2)). There were no statistically significant differences between the two groups in the echocardiographic trans-aortic pressure gradients (35.6 +/- 19 vs. 23.2 +/- 16 mmHg; P = 0.061) and the mean NYHA functional classification (1.10 +/- 0.3 vs. 1.01 +/- 0.10; P = 0.074) after AVR in the mid-term follow up. CONCLUSIONS: Moderate PPM has no negative effect on echocardiographic trans-aortic pressure gradients or the patients' NYHA functional status after AVR with a CarboMedics prosthesis in the mid-term follow up.
