Abstract

Aim: In this study we aimed to investigate, in isolated mitral stenosis (MS) patients, the relation between the severity of stenosis and left atrial (LA) mechanical functions in three phases (pump, conduit and reservoir phases). Material and Method: Study population consisted of 28 patients with MS (13 mild and 15 moderate-severe) and age-sex matched 14 healthy subjects. The study population underwent a comprehensive echocardiographic examination and LA volumetric measurements were obtained and from these phasic LA mechanical functions (reservoir, conduit and pump) were calculated. Results: Moderate to severe MS patients (38.9±4.2) had significantly decreased reservoir function when compared to both the con- trol (58.7±6.2) group and mild MS patients (60.7±6.4) (p <0.001 respectively ) and while pump functions (20.8±5.2) significantly decreased when compared to the control group (27.8±7.0) (p<0.006). There were no significant differences between mild MS patients (reservoir function 58.7±6.29, pump function 23.5±7.1) and control group(reservoir function 60.7±6.4, pump function 27.8±7.0) (p=0.67 and p=0.20, respectively). Besides, conduit function was comparable between the control group (45.3±8.6) and mild MS patients (46.0±6.6) (p=0.62) and it was significantly decreased in moderate to severe MS patients (22.5±6.0) when compared to both mild MS patients and control group (p:0.001 respectively). Correlation analysis revealed that as the severity of stenosis increases, reservoir and conduit functions were more significantly impaired than pump function. Conclusion: Left atrial reservoir and conduit functions more markedly impaired than pump function as the severity of stenosis increases in patients with MS.

Özet

Amaç: İzole mitral darlıklı (MD) hastalarda darlık derecesi ile sol atriyal (SA) fonksiyonlar arasındaki ilişkinin her üç SA mekanik faz için (pompa, kanal ve depo fazları) araştırılmasıdır. Gereç ve Yöntem: Çalışma grubu MD tanısı olan 28 hasta (13 hafif MD ve 15 orta-ileri MD) ve yaş-cinsiyeti eşleştirilmiş 14 sağlıklı bireyden oluşturuldu. Çalışmaya alınan tüm bireylerin SA hacimleri (maksimum, minimum ve pre-atriyal kontraksiyon hacim) ve SA fonksiyonları (pompa, kanal ve depo faz için) hesaplandı. Bulgular: Orta-ileri MD’li hastalarda SA depo fonksiyonu (38,9±42) hafif MD’li hastalar (58,7±6,2) ve kontrol grubuna (60,7±6,4) gö- re anlamlı olarak düşüktü (her üç grup için, p<0,001). Orta-ileri MD’li hastalarda pompa fonksiyonu (20,8±5,2) da kontrol grubuna göre (27,8±7,0) anlamlı olarak daha düşüktü ( p<0,006). Depo fonksiyonu (58,7±6,2)ile ve pompa fonksiyonu (23,5±7,1) için hafif MD’li hastalar (60,7±6,4) ile kontrol grubu (27,8±7,0 )arasında anlamlı fark yoktu (sırası ile p=0,67 ve p=0,20). Kanal fonksiyonu için hafif MD grubu (46,0±6,6) ile kontrol grubu (45,3±8,6) arasında anlamlı fark izlenmez iken ( p=0,62), orta-ileri MD grubunda (22,5±6,0 ) kontrol grubuna ve hafif MD grubuna göre anlamlı olarak daha düşüktü (sırası p<0,001). Korelasyon analizlerinde MD’nin derecesi arttıkça depo ve kanal fonksiyonlarının pompa fonksiyonuna göre anlamlı olarak daha fazla bozulduğu tespit edildi. Sonuç: Mitral darlıklı hastalarda darlık derecesi arttıkça SA depo ve kanal fonksiyonları pompa fonksiyonuna göre daha fazla bozulmaktadır.
