Abstract

Objectives: The aim of our study was to evaluate the influence of lung resection on cardiac functions by using tissue Doppler echocardiography. Study design: Nineteen consecutive patients (15 males, 4 females; mean age 55±8 years) undergoing major lung surgery (16 lobectomy, 3 pneumonectomy) were evaluated in a prospective design. Malignant lung cancer (n=15, 79%) was the major cause for lung surgery. Exclusion criteria were a history of myocardial infarction, angina, atrial fibrillation, valvular heart disease, major arrhythmias, diastolic dysfunction, heart surgery, and FEV1/FVC ratio lower than 60%. Two-dimensional Doppler echocardiography and tissue Doppler imaging (TDI) were performed one or two days before surgery and 4±2 weeks postoperatively.Results: Compared to the preoperative measurements, right and left atrial and ventricular dimensions did not differ after surgery (p>0.05). Left ventricular ejection fraction, left ventricular end-systolic and end-diastolic volumes were preserved postoperatively. The following Doppler parameters showed significant changes after surgery: mitral A wave (92±23 cm/sec vs. 105±27 cm/ sec, p=0.005), mitral E/A ratio (1.0±0.2 vs. 0.8±0.2, p=0.001), tricuspid A wave (65±19 cm/sec vs. 80±30 cm/ sec, p=0.006), and tricuspid E deceleration time (327±68 msec vs. 274±51 msec, p=0.01). Concerning TDI param- eters, there were significant differences in mitral E´/A´ ratio (1.0±0.4 vs. 0.8±0.3, p=0.03) and tricuspid E´ wave (9±2 cm/sec vs. 8±3 cm/sec, p=0.03) after surgery. Conclusion: Findings of our study suggest that systolic functions are preserved but diastolic functions are affected after major lung resection in a relatively short time period.

Özet

Amaç: Majör akciğer rezeksiyonlarının kardiyak fonk- siyonlar üzerine etkisi doku Doppler ekokardiyografi iledeğerlendirildi. Ça lış ma pla nı: Çalışmada majör akciğer rezeksiyonuuygulanan 19 hasta (15 erkek, 4 kadın; ort. yaş 55±8)ileriye dönük olarak incelendi. On altı hastada lobektomi, üç hastada pnömonektomi uygulandı. Akciğercerrahisinin en sık nedeni (n=15, %79) malign akciğerkanseriydi. Miyokart enfarktüsü, anjina, atriyal fibrilasyon, kalp kapak hastalığı, önemli aritmi, diyastolikdisfonksiyon, kalp cerrahisi öyküsü olan veya FEV1/FVCoranı %60’ın altında olan hastalar çalışmaya alınmadı.Tüm hastalar ameliyattan 1-2 gün önce ve ameliyattan4±2 hafta sonra ikiboyutlu Doppler ekokardiyografi vedoku Doppler görüntüleme ile değerlendirildi.Bul gu lar: Ameliyat öncesi ile karşılaştırıldığında, cerrahi sonrasında sağ ve sol atriyum ve ventrikül boyutlarında anlamlı değişiklik görülmedi (p>0.05). Sol ventrikülejeksiyon fraksiyonu, sol ventrikül sistol ve diyastolsonu hacimleri korunmuştu. Cerrahi sonrasında anlamlıdeğişim gösteren Doppler parametreleri şunlardı: mitralA dalgası (92±23 cm/sn ve 105±27 cm/sn, p=0.005),mitral E/A oranı (1.0±0.2 ve 0.8±0.2, p=0.001), triküspitA dalgası (65±19 cm/sn ve 80±30 cm/sn, p=0.006) vetriküspit E yavaşlama zamanı (327±68 msn ve 274±51msn, p=0.01). Doku Doppler ölçümlerinde ise, mitralE´/A´ oranı (1.0±0.4 vs. 0.8±0.3, p=0.03) ve triküspit E´dalgası (9±2 cm/sn ve 8±3 cm/sn, p=0.03) cerrahi öncesine göre anlamlı değişim gösterdi. So nuç: Bulgularımız, majör akciğer cerrahisinden sonraoldukça kısa bir zaman dilimi içinde sistolik fonksiyonlarda değişim olmazken, diyastolik fonksiyonların etkilendiğini göstermektedir.
