1/84. Mitral valve homograft for mitral valve replacement in acute bacterial endocarditis.Homograft use for aortic valve replacement (AVR) in aortic valve acute bacterial endocarditis (ABE) has gained in popularity, due mainly to the relative resistance of homografts to infection. Recent success with mitral valve homograft use led us to apply homograft mitral valve replacement (MVR) in a patient with severe ABE that was not amenable to valve repair. Following surgery, the patient improved rapidly with normalization of infection parameters and chest radiography, and was discharged home on postoperative day 11. Follow up echocardiography showed good function of the homograft mitral valve with no regurgitation. After four months, the patient had normal valve function, with no evidence of infection. In conclusion, MVR with a mitral valve homograft in the setting of ABE was satisfactory, though patient follow up was relatively short (four months).- - - - - - - - - - ranking = 1keywords = chest (Clic here for more details about this article) |
2/84. Expeditious diagnosis of primary prosthetic valve failure.Primary prosthetic valve failure is a catastrophic complication of prosthetic valves. Expeditious diagnosis of this complication is crucial because survival time is minutes to hours after valvular dysfunction. The only life-saving therapy for primary prosthetic valve failure is immediate surgical intervention for valve replacement. Because primary prosthetic valve failure rarely occurs, most physicians do not have experience with such patients and appropriate diagnosis and management may be delayed. A case is presented of a patient with primary prosthetic valve failure. This case illustrates how rapidly such a patient can deteriorate. This report discusses how recognition of key findings on history, physical examination, and plain chest radiography can lead to a rapid diagnosis.- - - - - - - - - - ranking = 1keywords = chest (Clic here for more details about this article) |
3/84. Cardiac disease late after chest radiotherapy for Hodgkin's disease: a case report.This report presents a case of occult constrictive pericarditis and mitral valve insufficiency following chest radiotherapy. A 44-year-old man had received radiotherapy for the treatment of Hodgkin's disease 8 years ago. At age 40 years, effusive pericarditis occurred and he was treated with intrapericardial drainage. biopsy revealed a fibrotic and thickened pericardium. He developed congestive heart failure 3 years later. The patient was found to have occult constrictive pericarditis and mitral valve insufficiency. He underwent mitral valve replacement, tricuspid annul plasty, and pericardiectomy. Although there is the benefit of cure for the Hodgkin's disease, the prognosis after treatment is affected by radiotherapy-induced heart disease. After radiotherapy of the chest and mediastinum, long-term cardiological follow-up is recommended in order to detecting patients with radiation-induced heart disease, such as the present case.- - - - - - - - - - ranking = 6keywords = chest (Clic here for more details about this article) |
4/84. Simultaneous repair of cardiovascular disorders and pectus deformity in a patient with Sprintzen-Goldberg syndrome: A case report.We report a 12-year-old girl with Sprintzen-Goldberg syndrome (SGS) who was complicated with annuloaortic ectasia with aortic regurgitation, mitral valve prolapse with mitral regurgitation, and a severe pectus excavatum. In this patient, aortic root replacement, mitral valve replacement, and sternal elevation were simultaneously performed, and a version of Ravitch's procedure that was technically modified to support the sternum was used for sternal elevation. This modified sternal elevation technique gave excellent operative exposure, and maintained chest wall stability after the operation.- - - - - - - - - - ranking = 1keywords = chest (Clic here for more details about this article) |
5/84. Diffuse alveolar hemorrhage syndrome due to 'silent' mitral valve regurgitation.A variety of clinical diseases are associated with diffuse alveolar hemorrhage. Although mitral valve disease can cause hemoptysis, it rarely is associated with diffuse alveolar hemorrhage at presentation. A 49-year-old woman was admitted to the hospital with the abrupt onset of fever, anemia, dyspnea, azotemia, and diffuse alveolar infiltrates. Two-dimensional echocardiography done several months earlier to evaluate atypical chest pain had been unremarkable. Fiberoptic bronchoscopy 2 days after admission to the hospital revealed fresh blood throughout the tracheobronchial tree. The infiltrates resolved rapidly and completely during systemic steroid therapy only to reappear as the steroids were tapered, suggesting a beneficial therapeutic response. Results of serologic evaluation were negative. Transbronchial biopsies showed inflammation and hemosiderin-laden macrophages; no specific diagnosis was established. The patient was scheduled for open lung biopsy. The surgeon was concerned about the history of chest pain and requested placement of a pulmonary artery catheter, which revealed severe pulmonary hypertension. Transesophageal echocardiography and subsequent cardiac catheterization showed severe mitral regurgitation. Mitral valve replacement resulted in complete elimination of symptoms.- - - - - - - - - - ranking = 6.2344486395196keywords = chest pain, chest (Clic here for more details about this article) |
6/84. Pseudoaneurysm in the mitral-aortic intervalvular fibrosa. A cause of mitral regurgitation.Left ventricular outflow tract pseudoaneurysm is an uncommon but potentially catastrophic complication of aortic valve surgery, aortic valve endocarditis or chest trauma. We describe a case of a left ventricular outflow tract pseudoaneurysm 1 month after an aortic valve replacement that caused a systolic compression of mitral valve and a severe regurgitation. The diagnosis was confirmed using transoesophageal echocardiography, magnetic resonance image and intraoperative endoscopy. Surgical repair of the pseudoaneurysm corrected the mitral regurgitation.- - - - - - - - - - ranking = 1keywords = chest (Clic here for more details about this article) |
7/84. Left atrial diverticulum associated with severe mitral regurgitation.diverticulum of the atrium is a rare and controversial clinical entity, and in the present case a left atrial diverticulum was associated with severe mitral regurgitation (MR). A 68-year-old female with the diagnosis of MR was referred for further cardiac evaluation. echocardiography revealed severe MR and an accessory cavity behind an enlarged left atrium. She underwent surgical valve replacement, but excision of the diverticulum was not done because its rupture seemed unlikely. A follow-up computed tomography performed 8 months postoperatively demonstrated disappearance of the diverticulum. The etiology of this atrial diverticulum is not clear, but the patient's MR may have played a role in its development.- - - - - - - - - - ranking = 2.7401586789266keywords = behind (Clic here for more details about this article) |
8/84. Critical left ventricular outflow tract obstruction due to accessory mitral valve tissue.Left ventricular outflow tract (LVOT) obstruction due to anomalous tissue tag arising from the mitral valve is a rare congenital cardiac anomaly. It generally becomes symptomatic during the first decade of life as exercise intolerance, chest pain, or syncope at effort. To date, only a few cases of critical systemic obstruction due to isolated mitral valve anomaly in neonates have been reported. We report the case of a neonate who was a few hours old and was referred in severe clinical condition due to critical left ventricular outflow obstruction resulting from an anomalous tissue tag of mitral valve origin.- - - - - - - - - - ranking = 3.1172243197598keywords = chest pain, chest (Clic here for more details about this article) |
9/84. Traumatic papillary muscle rupture.Papillary muscle rupture caused by blunt chest trauma is a relatively rare cause of mitral incompetence. To date only 25 cases of surgically corrected posttraumatic mitral regurgitation have been reported, of which only eight resulted from rupture of the anterolateral papillary muscle.- - - - - - - - - - ranking = 1keywords = chest (Clic here for more details about this article) |
10/84. Mitral valve plasty for mitral regurgitation after blunt chest trauma.A 21 year-old woman was admitted to our hospital because of chest and back pain after blunt chest trauma. On admission, consciousness was clear and a physical examination showed labored breathing. Her vital signs were stable, but her breathing gradually worsened, and artificial respiration was started. The chest roentgenogram and a subsequent chest computed tomographic scans revealed contusions, hemothorax of the left lung and multiple rib fractures. A transthoracic echocardiography (TTE) revealed normal left ventricular wall motion and mild mitral regurgitation (MR). TTE was carried out repeatedly, and revealed gradually progressive MR and prolapse of the posterior medial leaflet, although there was no congestive heart failure. After her general condition had recovered, surgery was performed. Intraoperative transesophageal echocardiography (TEE) revealed torn chordae at the posterior medial leaflet. The leaflet where the chorda was torn was cut and plicated, and posterior mitral annuloplasty was performed using a prosthetic ring. One month later following discharge, the MR had disappeared on TTE.- - - - - - - - - - ranking = 8keywords = chest (Clic here for more details about this article) |
