Abstract

Objective: The aim of this study was to investigate the response of heart to stress according to the size of the prosthetic valve in patients who had undergone mitral valve replacement by using dobutamine stress echocardiography (DSE) and to evaluate the relationship between the size of the prosthetic valve and cardiac recovery-remodeling process. Methods: Thirty-nine patients, who had undergone mitral valve replacement were compared in terms of left ventricular diameters, systolic functions and cardiac mass indexes in order to investigate the effect of the mechanical valve size on postoperative cardiac remodeling in this longitudinal study. They were divided into three groups according to their valve size: Group 1 (valve size29 mm, n=17). Statistical analysis was performed using Chi-square and one-way ANOVA tests to determine the statistical differences between the groups. The repeated measurements of two-way ANOVA test was used to analyze effects during long-term follow-up. Results: Only Group 1 patients achieved a significant decrease in terms of left ventricular mass index and end-diastolic diameter (138.3±29.7 g/m2 vs 86.6±15.6 g/m2 and 5.1±0.5 cm vs. 4.4±0.4 cm, p

Özet

Amaç: Bu longitüdinal çalışmada, mitral kapak replasmanı yapılan hastalarda prostetik kapak çaplarının kardiyak strese cevabı ve cerrahiyi takiben kapak çapının iyileşme-yeniden yapılanma üzerine etkilerinin araştırılması planlanmıştır.Yöntemler: Mitral kapak replasmanı yapılan 39 hasta, mekanik kapak çapının postoperatif kardiyak yeniden yapılanma üzerine etkisinin araştırılması amacı ile ventrikül çapları, sistolik fonksiyonları ve kardiyak kitle indeksleri açısından karşılaştırılmıştır. Hastalar protez kapak çapına göre 3 gruba ayrılmıştır. Grup 1- kapak çapı 29 numaranın altı hastaları (n=11), Grup 2- 29 numara olan hastaları (n=11) ve Grup 3- kapak çapı 29 numaranın üstünde olan hastaları içermektedir (n=17). İstatistiksel analiz için Ki-kare ve ANOVA testleri kullanılmıştır.Bulgular: Sadece Grup 1’deki hastalarda sol ventrikül kitle indeksi ve diyastol sonu çapında istatistiksel açıdan anlamlı azalma tespit edilmiştir (138.3±29.7 gm/2 ile 86.6±15.6 g/m2 ve 5.1±0.5 cm ile 4.4±0.4 cm, p
