Intravenous leiomyomatosis (IVL) is a rare benign tumor that originates from uterus, and sometimes extends to the right heart. We report a case of IVL that extended to right atrium through the inferior vena cava (IVC) which was resected using partial cardiopulmonary bypass. Multi detector computed tomography and ultrasound played a vital role in arriving at the diagnosis. Complete resection of tumor in the heart and great vein, and separation of the tumor stump from the IVC are essential in the treatment of IVL.
The long-term results of mitral valve repair for anterior leaflet prolapse are satisfactory, with low mortality and morbidity. In particular, chordal replacement using temporary Alfieri stitch is a simple and effective procedure.
We reviewed our experience of mitral valve repair techniques for extended commissural prolapse involving complex prolapse of either or both leaflets, due to chordal rupture or elongation. Between June 1991 and January 2005, 21 of 210 patients who underwent mitral valve repair for mitral regurgitation had extended commissural prolapse involving either or both of the anterior and posterior leaflets. There were 17 (81%) patients with degenerative and 4 (19%) with infective endocarditis. The distribution of diseased mitral commissural lesions was: posteromedial commissure in 14 (67%) patients, anterolateral in 6 (29%), and bilateral in 1 (5%). Reconstructive techniques included leaflet folding plasty in 10, resection-suture in 6, the sliding technique in 2, commissuroplasty in 2, and chordal shortening in 1. There were no perioperative deaths; postoperative mitral regurgitation was none or trivial in 19 patients and mild in 2. The mean follow-up period was 54 months (range, 2-155 months), and no patient required re-operation. There was one late death from a noncardiac cause at 103 months. Mitral valve repair for extended commissural prolapse is satisfactory. We consider leaflet folding plasty and its modification to be effective in patients who require extensive leaflet resection in the commissural area.
The purpose of this study was to define the role and indications of partial left ventriculectomy (PLV) in children with end-stage dilated cardiomyopathy (DCM). Clinical data were collected by retrospective chart review of children with DCM who were treated from 1997 to 2000. Four patients underwent PLV (PLV group) and 5 patients were managed without PLV (non-PLV group). In the PLV group, 2 patients are well 18 and 35 months postoperatively. One infant survived 6 months and then successfully underwent heart transplantation, and the other child died of hemoptysis 2 weeks postoperatively. Factors affecting outcome were preoperative status, in particular whether surgery was performed urgently or electively. In the non-PLV group, 4 patients were well controlled by medical treatment and 1 infant underwent mitral valve replacement for severe mitral regurgitation. The cardiothoracic ratio ranged from 72% to 76% in the PLV group and from 45% to 60% in the non-PLV group. The percentage of the expected left ventricular diastolic dimension ranged from 184% to 218% in the PLV group and from 109% to 163% in the non-PLV group. Ejection fractions in the PLV group were from 10% to 22% and from 36% to 56% in the non-PLV group. The serum brain natriuretic peptide concentration was above 1,200 pg/ml in the PLV group and below 168 pg/ml in the non-PLV group. In conclusion, PLV is indicated for selected children with end-stage DCM, and is most appropriate when medical therapy is not effective and heart transplantation is unavailable.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
