New semiautomated Doppler method for quantification of volumetric flow: intraoperative validation with multiplane transesophageal color Doppler imaging.
We have validated a new semiautomated method for quantification of volumetric flow applied to multiplane transesophageal color Doppler mapping. This Doppler technique assumes only the incompressibility of the fluid and includes variations of flow area. By computing velocity vectors across a surface normal to the point of scanning, volumetric flow can be measured independently of the angle of incidence between the ultrasonic beam and the direction of blood flow. ⋯ The results were compared with those obtained by the thermodilution technique. The mean of the differences between the thermodilution technique and color Doppler echocardiography was 0.06 +/- 0.866 L/min for the mitral valvular flows (mean of differences [thermodilution-color Doppler] &/- 2 SDs of differences). Thus mitral valvular volumetric flow measured by this color Doppler method showed a close agreement to the thermodilution technique during surgery.

Case ReportsTransesophageal echocardiographic detection of complications after Cabrol's procedure.
Cabrol's procedure represents an improvement on earlier surgical techniques used in the management of a patient with aortic insufficiency associated with an aneurysm of the ascending aorta. We report a patient in whom the diagnosis of complications after a Cabrol procedure was facilitated by transesophageal echocardiography. The role of transesophageal echocardiography in the follow-up of these patients is discussed.

Case ReportsLeft atrial myxoma presenting with embolism to the aorta.
We present a patient with left atrial myxoma embolizing to the ascending aorta. The features have not been reported previously and were diagnosed with transesophageal echocardiography.

ReviewDiagnosis and treatment of iatrogenic femoral artery pseudoaneurysm: a review.
A pseudoaneurysm is a pulsatile hematoma that communicates with an artery through a disruption in the arterial wall. Femoral pseudoaneurysm is a common complication of invasive procedures. It occurs in 0.1% to 0.2% of diagnostic angiograms and 3.5% to 5.5% of interventional procedures. ⋯ Larger femoral pseudoaneurysms may lead to complications including rupture and compression of the adjacent femoral vein (with resulting venous thrombosis) or of the femoral nerve. Treatment may be surgical. However, recently it has been shown that direct, noninvasive compression of the pseudoaneurysm stops the blood flow in the communication and leads to pseudoaneurysm clotting and obliteration.
