1/9. Surgical correction of unusual double-outlet right ventricle.This paper presents the case history of an 8-year-old girl who had total situs inversus and double-outlet right ventricle with pulmonary stenosis and severe tricuspid insufficiency in the presence of dextrocardia with ventricular discordance. A successful repair was performed using the Rastelli technique in conjunction with replacement of the tricuspid valve with a Bjork-Shiley prosthesis. The postoperative course was uneventful, and follow-up catheterization revealed a good operative result. However, the patient died suddenly during an emotionally upsetting period about two months after the operation. Postmortem examination revealed only signs of moderately severe cardiac decompensation. Some anatomical and embryological comments are made.- - - - - - - - - - ranking = 1keywords = motion (Clic here for more details about this article) |
2/9. Modified septal myectomy and repair of mitral valve apparatus for the treatment of hypertrophic cardiomyopathy.A modified technique is described of septal myectomy using a resectoscope and mitral valve repair to relieve left ventricular outflow tract obstruction and correct mitral regurgitation in a young patient with hypertrophic cardiomyopathy. This modification offers better control over the extent of septal tissue excision and may reduce the incidence of iatrogenic ventricular septal defect. Using this procedure it was possible to correct systolic anterior motion of the anterior mitral leaflet while obviating the need to replace the mitral valve.- - - - - - - - - - ranking = 1keywords = motion (Clic here for more details about this article) |
3/9. Familial aneurysms of the interventricular septum.Congenital aneurysms of the interventricular septum were found in a 29 year old man and his four year old son. Both were symptom free. In both, M mode and cross sectional echocardiography showed an aneurysm in the mid-muscular trabecular portion of the ventricular septum with considerable paradoxical motion of the aneurysmal segment. Otherwise the chamber dimensions, intracardiac structures, and cardiac function were normal for age. Congenital aneurysm of the interventricular septum is rare and these familial cases may be unique.- - - - - - - - - - ranking = 1keywords = motion (Clic here for more details about this article) |
4/9. Abnormal mitral valve motion associated with ventricular septal defect following acute myocardial infarction.It is often difficult to make the clinical distinction between acute mitral regurgitation caused by papillary muscle dysfunction or rupture and ventricular septal defect complicating an acute myocardial infarction. A case of a patient with rapidly progressive congestive heart failure and a loud murmur is presented. echocardiography strongly suggested the presence of a flail posterior mitral leaflet. However, the patient was subsequently found to have rupture of the interventricular septum. This diagnosis was made with bedside right heart catheterization and was later confirmed by left ventriculography and direct inspection at the time of surgery. The mitral valve apparatus was completely normal. Thus this case demonstrates the apparent lack of specificity of the accepted echocardiographic criteria for flail mitral leaflet and acutely ruptured interventricular septum, and the potential necessity of cardiac catheterization to distinguish between these entities.- - - - - - - - - - ranking = 4keywords = motion (Clic here for more details about this article) |
5/9. Echocardiographic recognition of ventricular septal aneurysm--a case report.The noninvasive detection of an aneurysm of the interventricular septum may be predictive of spontaneous closure of a ventricular septal defect. Moreover, in patients with audible systolic clicks the distinction must be made between septal aneurysm and mitral valve prolapse. The current report describes the echocardiographic visualization and pattern of motion of an aneurysm of the membranous ventricular septum. The diagnosis was made by both single crystal and real-time cross-sectional, multiple crystal ultrasound techniques prior to catheterization. These findings from the basis of the present study.- - - - - - - - - - ranking = 1keywords = motion (Clic here for more details about this article) |
6/9. The pediatric cardiovascular surgery patient: a case study.The pediatric cardiovascular surgery patient has many needs, based not only on the complexity of the surgical procedure, but also on anatomic, physiologic, and emotional differences. These differences have implications for nursing care in the postoperative period. This article focuses on the special needs of a child who required correction of a congenital heart defect. The specialized knowledge required by the pediatric critical care nurse to make accurate assessments of the child's status and to intervene appropriately are emphasized. Issues surrounding the care of the family of the child who experiences cardiac surgery are highlighted.- - - - - - - - - - ranking = 1keywords = motion (Clic here for more details about this article) |
7/9. Echocardiographic findings in left ventricular to right atrial shunts.The echocardiographic abnormalities of tricuspid valve motion in 2 patients with left ventricular to right atrial shunts are described. In both patients the abnormal anatomy was defined at surgery, in one patient the shunt being above the tricuspid valve leaflets (supravalvar) and in the other patient through the septal leaflet (intravalvar). Different patterns of tricuspid valve systolic fluttering were seen in these two cases and the possible reasons for this are discussed. After surgical closure of the defects the systolic fluttering of the tricuspid valve was no longer observed. echocardiography appears to be useful in detecting the presence of left ventricular to right atrial shunts which otherwise may be difficult to diagnose.- - - - - - - - - - ranking = 1keywords = motion (Clic here for more details about this article) |
8/9. Fibrous tissue overgrowth and prosthetic valve endocarditis: report of a case.Mechanical valve stenosis without restricted occluder motion and paravaluvular leakage developed in a patient who had undergone patch closure of partial atrioventricular septal defect and replacement of the left atrioventricular valve 13 years previously. Dense calcification of the supravalvular region was shown in a cineradiogram, whereas transthoracic and transesophageal echocardiography failed to reveal any obstructive mechanism. Elevated transprosthetic pressure gradient with unrestricted occluder motion suggested prosthetic valve stenosis resulting from fibrous tissue overgrowth, although this was not visualized by the modern diagnostic imaging tools. reoperation confirmed calcified fibrous tissue overgrowth obstructing the mechanical valve inflow. Examination of resected tissue revealed prosthetic valve endocarditis due to alpha-streptococcus. Paravalvular leakage accompanying fibrous tissue overgrowth may indicate the presence of prosthetic valve infection even if the clinical manifestations are scarce.- - - - - - - - - - ranking = 2keywords = motion (Clic here for more details about this article) |
9/9. Familial occurrence of congenital aneurysm of the muscular interventricular septum.Congenital aneurysms of the muscular interventricular septum are rare. We report two brothers with this disease and their father, who had marked thinning of part of the muscular interventricular septum with paradoxical motion. These cases lend support to the idea that these aneurysms are the result of an inherited defect in the myocardium.- - - - - - - - - - ranking = 1keywords = motion (Clic here for more details about this article) |
