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.

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.

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.

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 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 incidence and importance of tricuspid valve regurgitation after a blunt chest injury has risen with the increase in the number of automobile accidents and steering wheel traumas. This kind of injury has been reported more frequently in the last decade because of the better diagnostic procedures and understanding of the pathology. However, tricuspid valve regurgitation following a blunt chest injury can still be easily missed because most patients do not show symptoms at the time of the trauma. A 55-year-old male patient presented himself at our facility after suffering a chest injury from an automobile accident. His transthoracic echocardiography (TTE) revealed severe tricuspid valve regurgitation due to the prolapse of his anterior valve leaflet. We report a case of asymptomatic tricuspid regurgitation that developed after a blunt chest injury.

A 6 year-old, spayed female, Maltese dog was presented with precordial thrill and mild coughing. Thoracic auscultation revealed a grade V/VI systolic murmur with maximal intensity over the left apex characterized by musical murmur. Echocardiography revealed mild myxomatous degeneration of mitral valve and ruptured chordae tendineae. Musical murmur was produced due to the vibration of ruptured piece of chordae tendineae along with regurgitant flow. After treatment with furosemide and ramipril, clinical signs resolved and precordial thrill reduced. This case report describes typical clinical signs and phonocardiogram of musical murmur in a dog with acute chordae tendineae rupture.

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.
