Case ReportsLeft atrial hematoma complicating inferior myocardial infarction.
Intramyocardial dissecting hematoma after myocardial infarction is a rare condition. Previous reports have documented that these hematomas form almost exclusively in the myocardium adjacent to the culprit coronary lesion. We report a case of coexistent intramyocardial dissecting hematoma and ventricular rupture that arose as a consequence of a distal right coronary artery occlusion. Unusually, there was a very long dissection plane, which crossed the atrioventricular groove, with the hematoma manifesting on the opposite side of the heart (left atrium) to the infarcted myocardium (inferior wall).

Comparative StudyComparison of image quality between a narrow caliber transesophageal echocardiographic probe and the standard size probe during intraoperative evaluation.
Transesophageal echocardiography (TEE) has become an integral part of the evaluation and monitoring of patients during cardiac operation. Until recently, the smallest TEE probe with multiplane imaging measured 13 mm in diameter. This size is now standard for adult TEE probes. Recently, a new TEE probe has become available (MiniMulti TEE probe, Philips Medical Systems, Andover, Mass), which has a diameter of 8 mm. Although using a smaller probe is attractive, the quality of images it generates when used in adults has not yet been examined. ⋯ In the adult, the larger probe provides better images, particularly of the RV and LV. In addition, important findings may be missed with the smaller probe. However, if the adult probe cannot be passed, the pediatric probe is a reasonable alternative.

Case ReportsLeft ventricular hydatid cyst presenting with acute ischemic stroke: case report.
Cardiac hydatid cysts are rarely seen. The presentation of an acute stroke secondary to embolization from a cardiac hydatid cyst is also rare. We report a young boy with left ventricular hydatid cyst who presented with acute ischemic stroke.

In vivo short-term Doppler hemodynamic profiles of 189 Carpentier-Edwards Perimount pericardial bioprosthetic valves in the mitral position.
We sought to determine the hemodynamic performance of the Carpentier-Edwards Perimount pericardial valve in the mitral position. We reviewed the Doppler echocardiographic data on 189 patients (110 women; 68 +/- 12 years of age) who were implanted with this valve (7.6 days +/- 13 postoperatively) at our institution between September 2000 and May 2002. The average ejection fraction was 47%. ⋯ The average effective orifice area by continuity equation (83 valves) was 1.5 +/- 0.5 cm2. The mitral regurgitation was graded mild or less in 97.5% of all valves. This is the largest series establishing the favorable hemodynamic behavior of the different sizes of a new Perimount mitral valve, and the reported data could serve as a reference.

Case ReportsEffect of a kink in unilateral pulmonary artery anastomosis on velocities of blood flow through bilateral pulmonary vein anastomoses in living-donor lobar lung transplantation.
Intraoperative transesophageal echocardiography is generally performed to detect vascular complications during lung transplantation. We report a case with a kink in pulmonary artery (PA) anastomosis suggested by an abnormal flow profile of pulmonary vein (PV) anastomoses during living-donor lobar lung transplantation. ⋯ Then, the patient's PA pressure elevated abnormally and a kink in the left PA anastomosis was found. Careful monitoring of PV anastomoses may enable detection of not only an abnormality of PV anastomoses but also that of PA anastomoses, especially in living-donor lobar lung transplantation.
