Abstract

AIM: This study was conducted to investigate whether pulmonary venous flow variables measured by transthoracic Doppler echocardiography can help identify elevated left ventricular end-diastolic pressure (LVEDP). METHODS: The study included 63 patients in whom left heart catheterization and coronary angiography were performed. Adequate pulmonary venous flow recording were obtained in 60 patients. RESULTS: Pulmonary venous A wave exceeding the duration of mitral A wave predicted LVEDP>15mm Hg with a sensitivity of 0.83 and a specificity of 0.86. This difference in flow duration correlated moderately with the increase in LVEDP (r=0.64. SEE=8.1, p<0.001). Sensitivity of a pulmonary venous A wave velocitiy >35.cm/sn .for identifying a LVEDP>15 mm Hg was 0.80. with a specificitiy of 0.86. CONCLUSION: Measurement of the pulmonary venous flow variables by transthoracic echocardiography may he practical approach for estimation of LVEDP.

Özet

AMAÇ: Transtorasik Doppler ekokardiyografi ile elde edilen pulmoner venöz akım değişkenlerinin, yüksek sol ventrikül diyastol sonu basıncını (SVDSB) tahmindeki rolünün saptanması amaçlandı. YÖNTEM: Bu amaçla sol kalp kateterizasyonu ve koroner anjiyografi yapılan 63 olgu çalışma kapsamına alındı. Yeterli pulmoner venöz akını kayıtları 60 hastada elde edildi. BULGULAR: Pulmoner venöz A dalga süresinin mitral A dalga süresini aşmasının SVDSB' nın >15mm Hg olmasını tahminde %83 duyarlılık %86 özgüllüğe sahip olduğu saptandı. Akım süresindeki bu farkın sol ventrikül diyastol sonu basıncındaki artış ile orta derecede korelasyon gösterdiği bulundu (r=0.64, SEE=8.1, p 35cm/sn olması, SVDSB'nın>l5mm Hg olmasını tahminde %80 duyarlılık %86 özgüllüğe sahip idi. SONUÇ: Sonuç olarak pulmoner venöz akımların incelenmesi SVDSB 'nın tahmininde pratik bir yaklaşım olabilir.
