Among 21 patients with left atrial myxoma treated during the past 11 years in our institute, 3 patients had associated acquired heart disease which required concomitant cardiac surgery. Two patients had atherosclerotic coronary arterial disease, and underwent single coronary artery bypass grafting (CABG) and 4 CABGs in addition to removal of myxoma, respectively. Both of them received CABGs after removal of myxoma, because the intraoperative heart protection using retrograde coronary perfusion could afford the situation. Another patient had a huge left atrial myxoma associated with mitral and tricuspid regurgitation. She suffered from sudden heart failure caused by tumor obstruction of blood flow across the mitral valve, and an emergency surgery was performed. She underwent mitral valve replacement for annular dilatation with prolapse of both leaflets and tricuspid annuloplasty for annular dilatation, in addition to removal of myxoma. All of these 3 patients went a good postoperative course and are doing well now with no local recurrence. In this paper, preoperative and intraoperative evaluation, and surgical treatment of associated heart disease with left atrial myxoma were discussed.

We reported a successful tricuspid valve replacement in a 58-years old man, who had easy fatiguability after 14 years of a blunt chest trauma. The preoperative examination revealed a marked cardiomegaly with deformation of both ventricles and grade 4 tricuspid regurgitation caused by the prolapse of the anterior leaflet. The operative inspection revealed a left pericardial defect with a diameter of 10 cm and a torn anterior papillary muscle. Since a usual plastic procedure did not improve the regurgitation, a Carpentier-Edward bioprosthetic valve was implanted in the supra annular position. Atrioventricular conduction was preserved. The tricuspid valve was not resected to preserve the ventricular function. The patient recovered his own activity.

A case of traumatic tricuspid regurgitation with bilateral pericardial lacerations is presented. The patient was a 68-year-old male with a chief complaint of dyspnea on exertion, who had had chest contusion in an automobile accident 17 years before. Two dimensional echocardiography demonstrated a systolic prolapse of the tricuspid anterior leaflet resulting in massive regurgitation. The right atrial v wave was 25 mmHg. Intraoperative findings were as follows: Three healed tears of 4-6 cm long were present in the both sides of the pericardium. The chordae tendineae of the anterior leaflet were ruptured. The tricuspid valve was replaced with a SJM valve prosthesis. To our knowledge, no case of combined tricuspid insufficiency and bilateral pericardial laceration resulting from blunt injury has ever been reported.

To date, the relation between mitral stenosis (MS) and other associated cardiac valvular lesions has been reported by angiography and surgical pathologic study in patients with more advanced disease but has not been studied systematically by two-dimensional echocardiography and Doppler color flow mapping in a large referral population with a broader spectrum of severity. In addition, prior reports have suggested that up to 40% of patients with MS have mitral valve prolapse (MVP); however, because of recent developments in two-dimensional echocardiographic imaging and the definition of MVP, this association must now be reconsidered. The purpose of this study was to explore the association of other valvular lesions with MS and their relation to its severity and in particular to test whether MS is in fact associated with MVP with the frequency reported previously. We reviewed the studies of 205 consecutive patients (aged 61 +/- 14 years; range 26 to 87 years) with MS who were studied from 1992 to 1994 by two-dimensional echocardiography and Doppler color flow mapping to assess valvular stenosis, regurgitation, and MVP in patients with a range of severity of MS (28% mild, 34% moderate, and 38% severe MS based on mitral valve area). MS was associated with at least mild mitral regurgitation in 78% of patients (160/205), and pure MS was correspondingly uncommon (22%). There was an inverse relationship between the severity of MS and the degree of mitral regurgitation (p < 0.001). MS was frequently associated (54% of patients) with significant lesions of other valves, including aortic stenosis (17%), at least moderate aortic regurgitation (8%) and tricuspid regurgitation (38%), and tricuspid stenosis (4%). Tricuspid stenosis was associated with more severe MS (p < 0.01), and tricuspid regurgitation was more common in patients with mixed MS and regurgitation than in those with pure stenosis (60% versus 26% for at least moderate tricuspid regurgitation; p < 0.001). Mitral valve prolapse was present in only one patient (0.5%). Superior systolic bulging of the midportion of the anterior mitral leaflet toward the left atrium (but not superior to the annular hinge points) was seen in 22 patients (11%). Patients with such superior bulging had significantly lower mitral valve scores but a similar degree of mitral regurgitation compared with those without bulging. The majority of patients with MS (78%) have associated mitral regurgitation and significant lesions of the other cardiac valves (54%). The frequency of true MVP associated with chronic MS is much lower than reported previously. This may provide insight into the underlying pathophysiologic process, tending to shorten the chordae tendineae and leaflets to produce stenosis rather than elongate them to produce prolapse.

The purpose of this study was to determine the most discriminating clinical and echocardiographic features that are most helpful in correctly identifying Ebstein's anomaly of the tricuspid valve from other causes of tricuspid regurgitation. Ebstein's anomaly is an uncommon malformation of the tricuspid valve with diagnostic echocardiographic features. Other cardiac disorders associated with tricuspid valve regurgitation and predominate right-sided heart chamber enlargement can be misdiagnosed as Ebstein's anomaly. All patients who were referred to our institution between 1982 and 1995 with the diagnosis of Ebstein's anomaly but were found to have other abnormalities of the tricuspid value or right ventricle were identified. Their clinical, echocardiographic, and surgical records were reviewed retrospectively. Twenty-two patients (12 males and 10 females), aged 7 to 68 years (mean 33 years), were referred to our institution with the diagnosis of Ebstein's anomaly but were found to have another abnormality that mimicked clinical and diagnostic features of Ebstein's anomaly. The most common initial symptom was exercise intolerance (13 [59%] patients) followed by atrial arrhythmia (seven [32%] patients). Two patients had cyanosis. Three patients had paroxysmal and six had chronic atrial fibrillation/flutter. Cardiomegaly on chest x-ray film was noted in 18 (82%) patients. Referral diagnosis of Ebstein's anomaly had been made by echocardiography (12 patients), cardiac catheterization (four patients), both techniques (five patients), and echocardiography and magnetic resonance imaging (one patient). All 22 patients had predominate right atrial and right ventricular enlargement, and 18 (82%) of 22 patients also had right ventricular dysfunction. However, Ebstein's anomaly was confidently ruled out with repeat comprehensive echocardiography at our institution by establishing (1) absence of significant apical displacement of the septal tricuspid valve leaflet (> or = 8 mm/m2) and (2) lack of a redundant, elongated, anterior tricuspid valve leaflet in all 22 patients (100%). All had significant tricuspid regurgitation caused by tricuspid valve dysplasia (nine patients), tricuspid valve prolapse (four patients), trauma (four patients), right ventricular dysplasia (three patients), endocarditis (one patient), and annular dilation caused by free pulmonary regurgitation (one patient). In all 15 patients who subsequently underwent surgery (tricuspid valve repair [seven patients] or replacement [eight patients]), the absence of Ebstein's anomaly was confirmed. Echocardiographic absence of the characteristic degree of displacement of the septal leaflet of the tricuspid valve (> or = 8 mm/m2) and the presence of a nonelongated, nonredundant anterior tricuspid valve leaflet consistently excluded the diagnosis of Ebstein's anomaly. Under such circumstances, other anomalies of the tricuspid valve or right ventricle were consistently identified. Recognition of the mimics of Ebstein's anomaly had important surgical implications.

A 70-year-old woman who had fatiguability due to right heart failure seven years after receiving blunt chest trauma in a road traffic accident presented to our hospital. Preoperative echocardiography revealed severe tricuspid regurgitation resulting from prolapse of the anterior leaflet. The valve was repaired by chordal replacement with expanded polytetrafluoroethylene sutures and DeVega annuloplasty. At three months after surgery, the patient is in good clinical condition, and repeat echocardiography revealed only mild tricuspid regurgitation.

A seventy-year-old man was admitted at our hospital because of dyspnea. Echocardiogram and left ventriculogram showed an aneurysm formation of the membranous ventricular septum and small left-to-right shunt through ventricular septum defect and also severe mitral and tricuspid insufficiency. Operation was performed after medical therapy for congestive heart failure. During operation, mitral leaflets showed no organic lesions nor prolapse, but the annulus was dilated. The cause of mitral insufficiency, we thought, might be congenital, and the annulus dilatation was caused of mitral insufficiency, we thought, might be congenital, and the annulus dilatation was caused to produce tricuspid insufficiency secondary. The ventricular septal communication became small (diameter; 5 mm) and was associated with aneurysm formation of the remaining portion of the membranous septum. And the aneurysm, protruding to the septal leaflet of tricuspid valves, enhanced tricuspid insufficiency. It was reported by many authors that the aneurysm formation was related to spontaneous closure of ventricular septal defect. Patients with small ventricular septal defect, without any symptoms, must be followed intensively, or they might get cardiac complications, such as arrhythmia, right ventricular outflow obstruction, tricuspid insufficiency, and so on.

In patients with mitral (n=77: organic=49, functional=28) and tricuspid regurgitation (n=55: functional=54) quantified by angiography, the temporal variation of the proximal flow convergence region throughout systole was assessed by colour Doppler M-Mode, and peak and mean radius of the proximal isovelocity surface area for 28 cm/s blood flow velocity were measured. Additionally, the peak radius derived from two-dimensional colour Doppler was obtained. About 50% of the patients with mitral and tricuspid regurgitation showed a typical temporal variation of the flow convergence region related to the mechanism of regurgitation. The different proximal isovelocity surface area radii were similarly correlated to the angiographic grade in mitral and tricuspid regurgitation (rank correlation coefficients 0.55-0.89) and they differentiated mild to moderate (grade < or =II) from severe (grade > or =III) mitral and tricuspid regurgitation with comparable accuracy (82-96%). However, moderate mitral regurgitation due to leaflet prolapse in two patients was correctly classified by the mean M-mode radius and overestimated by both peak radii. Only half of the patients showed a typical variation of the flow convergence region related to the mechanism of regurgitation. The different proximal isovelocity surface area radii were suitable to quantify mitral and tricuspid regurgitation in most patients. However, in mitral regurgitation due to leaflet prolapse the use of the mean M-mode radius may avoid overestimation.

A rare case of isolated tricuspid regurgitation (TR) in a 65-year-old man is presented. Echocardiography revealed enlargement of the right atrium, dilatation of the tricuspid valve annulus without thickening or prolapse of the leaflets, and an intact atrial septum. No downward displacement of the tricuspid septal leaflet was observed by echocardiography. Mild mitral regurgitation and severe TR were detected on color flow Doppler studies. Cardiac catheterization indicated elevated right atrial pressure, with a pronounced V-wave. No left-to-right shunt was detected at the right atrium. At surgery, severe annular dilatation of the tricuspid valve (without organically diseased or deformed tricuspid leaflets) was observed, and tricuspid annuloplasty with a prosthetic ring performed. Postoperative echocardiography and right ventriculography showed trivial TR.

The case of an 83-year-old woman with a history of hypertension, valvular heart disease, atrial fibrillation, and cardiomegaly is presented. The patient also had progressive hoarseness of her voice and intermittent dysphagia. Ear, nose, and throat examination revealed left vocal cord paralysis. Echocardiography revealed severely dilated left (LA) and right atria (RA), moderate mitral regurgitation, severe tricuspid regurgitation, and prolapse of both these valves. A review of literature of Ortner's or cardiovocal syndrome is presented. Ortner's syndrome due to mitral valve prolapse has not been reported previously.
