The tricuspid valve is not a simple but a complex structure, tricuspid valve complex. This complex is composed of tricuspid orifice, annulus, valve leaflet, chordae tendineae and papillary muscles. There are flew articles about these structures. The authors studied tricuspid valve complex in 53 cases of normal korean adults, such as circumference of tricuspid annulus, the maximum diameter of the tricuspid orifice, height and breadth of the cusps, including commissures, the ratio of rough to clear zone, the number of scallops of posterior cusp, the number, length and pattern of arrangement of the several types of chordae, the number and morphological characteristics of papillary muscles.

The typical radiographic findings of pulmonary edema from the increased hydrostatic pressure shows centrally localized consolidation, which is known as a "butterfly or bat's wing" pattern. These terms describe the anatomic distribution of edema that uniformly involve the hilum and medulla of the lung but not the peripheral region of the lung parenchyma (cortex). We present a case of butterfly wing-like pulmonary edema on a chest radiograph by mitral regurgitation due to an idiopathic chordal rupture.

Post-traumatic tricuspid insufficiency is a rare condition and may be clinically silent and imprecise. The diagnosis may be difficult when it progreses slowly and other acute lesions exist concomittantly. Two-dimenstional Doppler echocardiography appears to be an essential procedure in diagnosting the rupture of chordae tendineae or papillary muscle following traumatic injury. We report a case of tricuspid insufficiency of which symptom developed 8 years later following a blunt chest trauma. The patient was operated by tricuspid vlave repair with chordal replacement and ring annuloplasty successfully. We would like to emphasize that patients sustaining major thoracic trauma should be carefully examine for possible blunt chest trauma including cardiac valve rupture or tear.

We report a successful repair of severe traumatic tricuspid regurgitation by PTFE chordal replacement and ring annuloplasty. A 64-year-old man with multiple trauma was referred to our department because of cardio- megaly on chest roentgenogram. Echocardiography showed moderate amount of pericardial effusion and severe tricuspid regurgitation with rupture of anterior papillary muscle. But he experienced progressive dyspnea, and chest roentgenogram showed progressive cardiomegaly. He underwent operation 4 months after trauma. The nterior papillary muscle was reinserted, and the valve was repaired by PTFE chordal replacements and ring annuloplasty. Postoperatively, the patient's functional status was improved, and there was trivial tricuspid regurgitation on echocardiographic examination.

A 69-year-old male presented with obstructive hypertrophic cardiomyopathy, mitral valve regurgitation, and myxomatous mitral valve prolapse. A spontaneous chordal rupture and acute severe mitral regurgitation resulted in abrupt clinical deterioration despite complete relief of severe left ventricular outflow tract obstruction and systolic anterior motion of the anterior mitral leaflet. The patient underwent extensive cardiac surgery due to intractable heart failure. Surgical procedures included a mitral valve replacement, a septal myectomy, and the Maze procedure.

BACKGROUND: Mitral valve repair for posterior mitral leaflet (PML) prolapse has been considered to be a standard treatment because of its high success rate and high level of patient satisfaction. The aim of this study was to evaluate the clinical results of two different techniques of PML prolapse, quadrangular resection (QR) and chordal replacement (CR). MATERIALS AND METHODS: The subjects consisted of 56 patients who had undergone mitral valve repair for PML prolapse between November 1997 and December 2010. The patients were divided into two groups according to surgical technique. Among them, 31 patients underwent QR (group QR) and 25 patients had CR (group CR). We reviewed the medical records of the patients retrospectively to compare the clinical outcomes of both groups. RESULTS: After mitral valve repair, the degree of mitral regurgitation (MR) in both groups decreased to the to a mild degree or less and the amount of remnant MR was slightly higher in the CR group but it was not statistically different. Three patients received mitral valve-related reoperation (2 in the QR group and 1 in the CR group). Freedom from mitral valve-related reoperation at 7 years was 93% for the QR group and 96% for the CR group and was not significantly different between the two groups. CONCLUSION: Both QR and CR showed excellent long-term results and were considered equally effective methods for PML prolapse.

BACKGROUND AND OBJECTIVES: The proportion of mitral regurgitation caused by chordae rupture has recently been seen to be increasing, as has the role of mitral valve repair in the treatment of chordae rupture. This study evaluated the clinical characteristics and trends of surgical treatment of chordae rupture. Additionally, we attempted to discern the usefulness of transthoracic echocardiography (TTE) in the preoperative diagnosis of chordae rupture. SUBJECTS AND METHODS: Forty patients (20 men, mean age:49+/-14) presenting with chordae rupture confirmed during surgery between January 1994 and April 2001 were included in this study. Clinical, TTE and surgical data were analyzed retrospectively. RESULTS: The cause of chordae rupture was idiopathic degeneration in 28 cases, rheumatic heart disease in 5, infective endocarditis in 6, and trauma in 1 case. The sites of rupture were the anterior leaflet (14), posterior leaflet (23), and anterior and posterior leaflets (3). Mitral valve repair was performed in 20 cases and mitral valve replacement was performed in 20 cases. Most mitral valve repairs were performed beginning in 1998 (17/20). Chordae rupture diagnosed by TTE numbered 14 cases (35%). CONCLUSION: Regurgitation caused by chordae rupture was primarily associated with idiopathic degenerative change. Posterior leaflet rupture was more frequent than anterior leaflet rupture. The use of mitral valve repair has been increasing since 1998.

The mitral valve complex is consisted of annulus, leaflets, chordae tendineae, papillary muscle (PMs) and surrounding left ventricle. Functional mitral regurgitation (MR) results from left ventricular remodeling such as dilatation or distortion, which displaces the PMs and then tethers the mitral leaflets, restricting leaflet coaptation. Undersized annuloplasty, which has been widely accepted as a simple and effective procedure for functional MR, sometimes worsens the tethering of posterior leaflet and induces recurrent MR. In order to overcome such problems, several additional procedures to the simple annuloplasty have been produced. Three dimensional echocardiography plays an essential role to understand the geometry of mitral valve complex and contributes greatly to decision making of the surgical strategy in functional MR and its postoperative assessment.
