As discussed in Video 3, a TTE, subcostal, four-chamber view (Video 1, Clip 1), although limited to some segments of basal-midventricular regions, suggested normal LV and RV size and systolic function. In the subcostal longitudinal view (Video 1, Clips 2, 3), an enlarged aorta was noted (2.65 cm [normal ≤ 2 cm]) with an intimal flap seen inside, compatible with aortic dissection. A parasternal long-axis view (Video 1, Clip 4) showed normal LV systolic function and no WMAs. The aortic root was dilated (4.3 cm [normal ≤ 3.5 cm]) with no intimal flap seen inside, and a trace aortic regurgitation (AR) jet was revealed on color Doppler imaging. A moderate to severe acute AR is present in nearly one-half of patients with type A aortic dissection. Accordingly, the absence of significant AR does not rule out the diagnosis of this type of dissection. Apical four- and two-chamber views (Video 1, Clip 5) showed normal RV and LV systolic function with no WMAs. In a modified apical two-chamber view (Video 1, Clip 6), the medium-distal portion of the descending thoracic aorta was seen behind the left atrium, with an intimal flap inside and two lumina noted. No pleural or pericardial effusion was noted. Pericardial effusion could be a complication of type A dissections and pleural effusion of type B dissections, both indicating aortic rupture into these cavities. Because the cranial portion of ascending aorta, aortic arch, and proximal thoracic descending aorta are not seen with the conventional TTE views, the next logical step would be to perform a suprasternal view to determine if a type A (involving the ascending aorta) or a type B dissection (not involving the ascending aorta) is present.
