BACKGROUND: In chronic aortic dissection, compression of the true lumen by the expanded false lumen may be a cause of left ventricular afterload elevation, which may result in diastolic dysfunction. We compared the left ventricular diastolic function by echocardiography between those patients who had double-barrel descending aortic dissection and those who did not. METHODS: Twelve patients (mean age, 61 +/- 12 years) with chronic type B aortic dissection were enrolled in this study. Patients in group I had double-barrel aortic dissection that had expanded the patent false lumen and narrowed the true lumen (n = 7, 58.3%), and patients in group II had a wider-caliber true lumen with a thrombosed false lumen (n = 5, 41.7%). We evaluated the left ventricular diastolic function with the transmitral flow pattern (E and A waves) with the pulsed Doppler method and flow propagation velocity (FPV) with color M-mode Doppler images, and classified its severity into grade I (abnormal relaxation), grade II (pseudonormalization) and grade III (restriction). RESULTS: All patients in group II had grade I diastolic dysfunction, with an E/A of less than 1.0. By contrast, 4 of the 7 patients in group I had grade II diastolic dysfunction, with an FPV/E of less than 0.6 and a pseudonormalized (> 1.0) E/A ratio (p = 0.081). Consequently, the E/A ratio was higher in group I than in group II (1.16 +/- 0.39 versus 0.68 +/- 0.18; p < 0.05). CONCLUSIONS: It is suggested that left ventricular diastolic function is severely reduced in the patients having aortic dissection with a double-barrel and narrowed true lumen.
