Giant Right Atrium in an Adult

ECHOCARDIOGRAPHY, Issue 10 2008
Vignendra Ariyarajah M.D.
Massive right atrial (RA) enlargement is certainly more common in children than in adults, owing to rare congenital anomalies. Indeed, the largest description of such chamber enlargement was noted in a child, where the RA volume was reported to be 900 ml. We now report one of the largest descriptions of the RA in an adult, in absence of tricuspid stenosis and other common adult associations of RA abnormality, such as chronic pulmonary disease, severe mitral valvular pathology with pulmonary hypertension, and pulmonary embolism or infarct. The RA volume was estimated to be well over 500 ml and was notably disproportionate to that of the left atrium and either ventricle. [source]


Is It Open or Is It Closed?

Thrombosis of a St. Jude's Tricuspid Valve Prosthesis
A 49-year-old woman with mitral and tricuspid mechanical valve prostheses developed marked weight gain with increasing abdominal girth and facial plethora 4 weeks after anticoagulation was temporarily interrupted for abdominal surgery. Transthoracic and transesophageal echocardiography documented severe tricuspid stenosis and regurgitation. The two discs of the tricuspid prosthesis were immobilized, half open and half closed. The prosthesis was replaced and the patient did well. [source]


Utilization of the Edge-to-Edge Valve Plasty Technique to Correct Severe Tricuspid Regurgitation in Patients with Congenital Heart Disease

Significant morbidity and mortality are related to tricuspid valve replacement. Tricuspid valve plasty is still a preferred choice. This report deals with our surgical experience in using the edge-to-edge valve plasty technique to correct severe tricuspid regurgitation in patients with congenital heart disease. Methods: From December 2002 to August 2007, severe tricuspid regurgitation was corrected with a flexible band annuloplasty and edge-to-edge valve plasty technique in nine patients with congenital heart disease. The age ranged from 7 to 62 years (average 24.4 years). Congenital cardiac anomalies included atrioventricular canal in five cases, secundum atrial septal defect in three cases, and cor triatriatum in one case. Results: No hospital death or postoperative morbidity occurred. No or trivial tricuspid regurgitation was present in six cases and mild tricuspid regurgitation in three cases at discharge. The follow-up ranged from 12 months to 70 months (average 39.3 months). No tricuspid stenosis was found. No to mild tricuspid regurgitation was present in eight cases, and moderate tricuspid regurgitation in one case at the latest follow-up. Conclusions: Edge-to-edge valve plasty is an easy, effective, and acceptable additional procedure to correct severe tricuspid regurgitation in patients with congenital heart disease. [source]


Transcatheter Closure of Congenital Ventricular Septal Defects: Experience with Various Devices

JOURNAL OF INTERVENTIONAL CARDIOLOGY, Issue 1 2003
RAMESH ARORA D.M.
Transcatheter closure of congenital ventricular septal defect (VSD) using various devices is gaining acceptance in selected cases of perimembranous and muscular defects, avoiding the inherent risks of cardiopulmonary bypass. The procedure was attempted in 137 patients having congenital defects using Rashkind Umbrella Device (RUD) in 29 patients, Amplatzer ventricular septal occluder (AVSO) in 107 patients, and Detachable Coil in one. All patients were selected using stringent criteria by detailed transthoracic echocardiography and/or transesophageal echocardiography. The location of VSD was perimembranous in 91 patients and was muscular trabecular in 46 patients. Seven patients had left ventricle (LV) to right atrium (RA) communication. Thirty-five patients with perimembranous and two with muscular VSD had aneurysm formation. The patients were 3 to 33 years old, and the diameter of VSD ranged from 3 to 12 mm. The pulmonary to systemic flow ratio was ,2:1 in 47 (34.3%) patients. The procedure was successful in 130 (94.8%) patients, with a success rate of 86.2% with RUD and 97.1% with AVSO. Residual shunt at 24 hours was seen in eight (32%) patients with RUD and in one patient (0.9%) with AVSO. Three (2.8%) developed transient bundle branch block, and two (1.9%) patients had complete heart block. New tricuspid stenosis and tricuspid regurgitation was observed in one patient each with AVSO. After immediate balloon dilatation, the mean pressure gradient across tricuspid valve decreased from 11 to 3 mmHg in the patient with tricuspid stenosis. On a follow-up of 1 to 66(mean 35.2 ± 10.7)months, the device was in position in all. None developed late conduction defect, aortic regurgitation, infective endocarditis, or hemolysis. At 9-month follow-up, the mean pressure gradient across the tricuspid valve was 3 mmHg in the patient with tricuspid stenosis. Complete occlusion of the shunt was achieved in 129 (99.2%) patients. One patient with RUD having persistent residual shunt underwent a second procedure with AVSO. Three out of 107 patients with AVSO had an unsuccessful procedure where the defect was perimembranous with a superior margin of defect less than 3 mm away from the aortic valve, and the specially designed perimembranous AVSO had to be retrieved because of hemodynamic compromise due to significant acute aortic regurgitation, whereas in all others, the defect was either ,3 mm away from the aortic valve or had aneurysm formation. All seven patients with LV to RA communication showed complete abolition of the shunt. Thus, in properly selected cases of perimembranous and muscular ventricular septal defects, the transcatheter closure is safe and efficacious using appropriate devices. The success rate is higher with AVSO compared with the previously used devices, as well as more successful for the muscular defects than those that are perimembranous in location.
