1/166. Left ventricular apical diastolic collapse: an unusual echocardiographic marker of postoperative cardiac tamponade.A 37-year-old woman was evaluated for signs and symptoms of cardiac tamponade 11 days after mitral valve replacement and tricuspid valve repair. The transthoracic echocardiogram showed a large, compartmentalized pericardial effusion that resulted in left ventricular apical diastolic collapse. Also noted were right ventricular posterior wall diastolic collapse and hemodynamic findings consistent with cardiac tamponade. This case highlights the atypical echocardiographic findings in patients with pericardial effusions after cardiac surgery.- - - - - - - - - - ranking = 1keywords = cardiac (Clic here for more details about this article) |
2/166. aortic valve regurgitation as the presenting sign of takayasu arteritis.takayasu arteritis is a rare chronic vasculitis primarily involving the aorta and its main branches. We report an adolescent girl with takayasu arteritis who presented with an isolated aortic valve regurgitation as part of a systemic inflammatory process. This patient was initially misdiagnosed as having rheumatic heart disease and the correct diagnosis was made only 1 year later. CONCLUSION: takayasu arteritis should be considered among the diagnostic possibilities in patients who present with an unexplained systemic inflammatory syndrome and a cardiac murmur.- - - - - - - - - - ranking = 9.7645305701278keywords = heart, cardiac (Clic here for more details about this article) |
3/166. Early proarrhythmia during intravenous amiodarone treatment.We present a case of early (within the first 24 hours) development of malignant torsades de pointes (TdP) associated with intravenous amiodarone therapy. After correction of predisposing factors (heart failure, hypokalemia, digoxin) amiodarone again resulted in torsades. This observation suggests that in patients who have experienced amiodarone-induced proarrhythmia, amiodarone administration under different, more stable clinical conditions may still be hazardous.- - - - - - - - - - ranking = 9.6216734272707keywords = heart (Clic here for more details about this article) |
4/166. Intrapericardial organized hematoma. A rare complication after open heart surgery.Intrapericardial organized hematoma, which compresses cardiac chambers late after open heart surgery, is extremely rare. We report a case of intrapericardial organized hematoma in a 63-year-old man who underwent aortic valve replacement 8 years prior, which may have aggravated rheumatic mitral valve regurgitation compressing the mitral valve anulus. Under extracardiopulmonary bypass and cardioplegic heart arrest, we removed the hematoma and replaced the mitral valve with a 27 mm St. Jude Medical valve. There were no bleeding points on the heart and pericardium at operation and no history of blunt chest trauma. The etiology of the hematoma is uncertain.- - - - - - - - - - ranking = 67.494571133752keywords = heart, cardiac (Clic here for more details about this article) |
5/166. Papillary fibroelastoma of the mitral valve 12 years after mitral valve commissurotomy.A 63 year-old woman who had had mitral valve commissurotomy 12 years earlier was seen because of rheumatic mitral stenosis and left brachial paresis due to cerebral embolism. On clinical evaluation, a diastolic rumble was heard over the mitral area, and the echocardiogram revealed a mass attached to the mitral subvalvular apparatus. The patient was operated on, and both the surgical and histologic findings depicted papillary fibroelastoma. This tumor may occur as an isolated lesion or be associated with mitral valve stenosis or other cardiac abnormalities, and it is an important source of emboli. Early echocardiographic diagnosis, followed by surgical excision, may avoid serious complications such as stroke, myocardial infarction, and sudden death.- - - - - - - - - - ranking = 0.14285714285714keywords = cardiac (Clic here for more details about this article) |
6/166. T wave alternans and acute rheumatic myocarditis: a case report.T wave alternans is an uncommonly recorded cardiac rhythm. We report here an unusual case of a 13-year-old girl with acute rheumatic carditis and acute nephritis, who developed T wave alternans associated with a prolonged QT interval. These electrocardiographic changes were evident only after the initial acute stage of the disease process and should be borne in mind for patients with acute rheumatic carditis as they may be associated with more malignant arrhythmias.- - - - - - - - - - ranking = 0.14285714285714keywords = cardiac (Clic here for more details about this article) |
7/166. Maze procedure and homograft replacement of a rheumatic mitral valve.A 64-year-old woman presented with congestive heart failure due to severe mitral valve stenosis and chronic atrial fibrillation. A Maze III procedure was performed, and the mitral valve replaced with a mitral homograft. Postoperatively, the patient regained normal sinus rhythm, had trivial mitral regurgitation, regained her atrial transport function, and had improved myocardial function.- - - - - - - - - - ranking = 9.6216734272707keywords = heart (Clic here for more details about this article) |
8/166. The prophylaxis of acute rheumatic fever in a pair of monozygotic twins. The public health implications.Recurrent acute rheumatic fever and rheumatic heart disease can be prevented by antibiotic intervention. We report the case of genetically identical twins, one of whom had overt rheumatic fever, received penicillin prophylaxis and did not have rheumatic heart disease. The other must have had inapparent rheumatic fever, received no chemotherapy prophylaxis and proceeded to develop rheumatic heart disease. A greater clinical and laboratory vigilance is required for the diagnosis of acute rheumatic fever in the asymptomatic identical twin of a patient with rheumatic fever. This case provides further evidence of a genetic predisposition to rheumatic fever and demonstrates the continued value of penicillin in the prophylaxis of acute rheumatic fever. It emphasises the need to maintain the integrity of preventive programmes against rheumatic fever worldwide. Studies which explore the HLA and other genetic linkages with rheumatic fever should be encouraged.- - - - - - - - - - ranking = 28.865020281812keywords = heart (Clic here for more details about this article) |

Partial atrioventricular septal defect causing confusion with rheumatic heart disease in children in Harare--case reports.Four cases of partial atrioventricular septal defect (AVSD) [corrected] which had been confused with rheumatic heart disease are presented.

10/166. Fetal hydantoin syndrome with rheumatic valvular heart disease.research has shown that anticonvulsants are teratogens and pose a risk for fetal malformations. Though Fetal Hydantoin syndrome (FHS) was first reported by Langhman and others, wide phenotypic variability of this syndrome has lead many clinicians to question its very existence. We report a twelve year old girl with FHS with rheumatic valvular heart disease.- - - - - - - - - - ranking = 48.108367136353keywords = heart (Clic here for more details about this article) |
