RESUMO

Hemolytic anemia after mitral repair and annuloplasty ring placement is very uncommon, and rarely described. The case is presented of a 53-year-old woman who developed severe mitral regurgitation and transfusion-dependent hemolytic anemia following mitral valve repair with a Carpentier-Edwards annuloplasty ring, which included transposition of chordae tendineae from the posterior leaflet to the anterior leaflet. Transesophageal echocardiography suggested that the transposed chordae tethered the anterior leaflet, causing malcoaptation of the leaflets. This resulted in central regurgitation divided by the chordae tendineae, producing two turbulent flow jets causing hemolysis. At reoperation, these chordae were removed and two longer Gortex neochordae to the anterior leaflet were placed with subsequent resolution of the anemia. To the authors' knowledge, this is the first case of hemolytic anemia caused by transposed mitral valve chordae tendineae from the posterior to the anterior leaflet.

RESUMO

A 68-year-old white female presented with two years of progressively worsening dyspnea. Echocardiography revealed a large right atrial mass and partial obstruction of the inferior vena cava. Further imaging revealed a cystic dense mass in the inferior vena cava and right atrium. Immunohistochemical stains were consistent with leiomyosarcoma. Intraoperatively, the tumor was noted to originate from the posterior aspect of the inferior vena cava. The patient underwent successful resection of the mass. Adjuvant radiation therapy was completed. The patient's dyspnea gradually improved and she continues to remain disease free five years post-resection.

RESUMO

To correlate prespecified P-wave morphologies with echocardiographically derived left atrial volumes (LAVs), we studied a convenience sample of 71 patients with predominantly normal left ventricular systolic function (mean ejection fraction = 58.2% +/- 6.6%) who underwent concurrent 2-dimensional echocardiogram and 12-lead electrocardiogram. Left atrial volume was calculated from apical end-systolic images by the biplane method of disks and was indexed for body surface area (BSA). Electrocardiograms were assessed manually with calipers, measuring leading edge to leading edge. Patients included 34 men and 37 women with a mean age of 53 +/- 14 years. P-wave duration/PR-segment duration in lead II and depth and duration of terminal P wave in lead V1 (P terminal force) correlate poorly with LAV and provided only modest predictive power (area under receiver operating characteristic curve = 0.466-0.619 and r = 0.30-0.42, P = .014-.021). Total P-wave duration in lead II correlated moderately (r = 0.47, P < .001) and predicted LAV (LAV/BSA = 8.0 + 0.2 [P-wave duration in lead II]), as did P-wave area in lead II (r = 0.49, P < .001) (LAV/BSA = 18.6 + 1.7 [P-wave duration in lead II]). The 4 P-wave morphologies were found to be poorly sensitive but highly specific for left atrial enlargement.
