1/55. Reversible catecholamine-induced cardiomyopathy in a heart transplant candidate without persistent or paroxysmal hypertension.BACKGROUND: Both dilated and hypertrophic cardiomyopathy have been reported in patients with pheochromocytoma, who were almost always hypertensive. The outcome frequently has been fatal, yet cardiac dysfunction can be reversible after medical or surgical therapy for the pheochromocytoma. methods: We report the case of a patient with dilated cardiomyopathy without persistent or paroxysmal hypertension, who was found to have a pheochromocytoma during initial medical evaluation. RESULTS: The identification and treatment of the pheochromocytoma led to significant improvement in cardiac function and cardiac transplantation was avoided. CONCLUSIONS: This case illustrates some unusual features in pheochromocytoma-induced cardiomyopathy: (1) absence of persistent or paroxysmal hypertension, (2) initial presentation with acute myocardial infarction and normal coronary arteries, and (3) recurrent episodes of nonsustained ventricular tachycardia.- - - - - - - - - - ranking = 1keywords = cardiomyopathy (Clic here for more details about this article) |
2/55. Diagnosis and management of pheochromocytoma during pregnancy: a case report.pheochromocytoma is known to increase morbidity and mortality. We describe a case of pheochromocytoma during pregnancy. A patient was transferred to our hospital during gestational week 15 with severe hypertension, acute pulmonary edema, and cardiomyopathy. One day after transfer, she had a spontaneous abortion of the fetus. One week after hospital transfer, she developed acute dyspnea, supraventricular tachycardia degenerating into ventricular tachycardia, and respiratory failure requiring mechanical ventilation. pheochromocytoma caused by a right adrenal mass was diagnosed. The patient was treated with titrated doses of phenoxybenzamine, intravenous nicardipine, and metyrosine over a period of 3 weeks with resultant stabilization of her blood pressure. She underwent a successful right adrenalectomy 1 month after her initial presentation. Four months after surgery, all antihypertensive medications were discontinued and her blood pressure remained stable 1 year after the surgery. This case describes the maternal morbidity and fetal mortality that may be associated with pheochromocytoma during pregnancy.- - - - - - - - - - ranking = 0.14285714285714keywords = cardiomyopathy (Clic here for more details about this article) |
3/55. Dynamic left ventricular outflow tract obstruction in a patient with pheochromocytoma.Symmetric left ventricular hypertrophy or asymmetric septal hypertrophy associated with pheochromocytoma simulating hypertrophic obstructive cardiomyopathy have been rarely reported. In this report, we present a case with pheochromocytoma that had dynamic left ventricular outflow tract obstruction without asymmetric septal hypertrophy. A surface echo revealed resolution of the systolic anterior motion of the mitral valve and all Doppler evidence of left ventricular outflow tract obstruction following removal of the tumor. Dynamic left ventricular outflow tract obstruction seen in this patient was probably due to excessive secretion of cathecolamines by the tumor.- - - - - - - - - - ranking = 0.14285714285714keywords = cardiomyopathy (Clic here for more details about this article) |
4/55. Traumatic hemorrhage of occult pheochromocytoma: a case report and review of the literature.pheochromocytoma usually presents with gradual onset and mild to moderate symptoms, but may present acutely with severe symptoms. hemorrhage into pheochromocytoma is a rare cause of acute presentation that is often devastating to patients. We describe the case of a 34-year-old woman with hemorrhage into a previously undiscovered pheochromocytoma following a fall on a patch of ice. This is the first reported case of hemorrhagic pheochromocytoma associated with traumatic injury. Despite removal of the tumor within 18 hours of presentation, the patient suffered severe complications of massive catecholamine excess, including shock, cardiomyopathy, and adult respiratory distress syndrome. Animal studies have shown that early treatment with alpha blockers can prevent some, if not all of these complications. Proper management of hemorrhagic pheochromocytoma should include a high index of suspicion with early diagnosis and treatment with alpha blockers and surgical resection of the tumor when the patient is stable enough to tolerate the procedure.- - - - - - - - - - ranking = 0.14285714285714keywords = cardiomyopathy (Clic here for more details about this article) |
5/55. pheochromocytoma crisis, cardiomyopathy, and hemodynamic collapse.pheochromocytoma is a notorious clinical entity. Although suspicion is aroused by severe hypertension in young patients, this sign is often absent. We present a case in which early absence of hypertension and nonspecific signs and symptoms led to failure of prompt diagnosis. The delay proved fatal when the patient developed fulminant pheochromocytoma crisis. This case illustrates a variety of clinical features seen from the vantage of the evolution of the disease as it went unrecognized. The patient's course underscores the importance of familiarity with the gamut of manifestations for timely diagnosis, and the priority of the latter given the looming risk of overwhelming complications.- - - - - - - - - - ranking = 0.57142857142857keywords = cardiomyopathy (Clic here for more details about this article) |
6/55. dexamethasone-induced cardiogenic shock rescued by percutaneous cardiopulmonary support (PCPS) in a patient with pheochromocytoma.A 52-year-old man with pheochromocytoma had cardiogenic shock and was rescued using a percutaneous cardio pulmonary supporting system. After recovery, diagnostic tests including metaiodobenzylguanidine scintigraphy and computed tomography, revealed the pheochromocytoma which was confirmed by histology. It was postulated that the acute episode was induced by intra-joint dexamethasone, which increased the production of epinephrine and augmented the sensitivity of cardiomyocytes for catecholamine, thereby inducing the cardiomyopathy.- - - - - - - - - - ranking = 0.14285714285714keywords = cardiomyopathy (Clic here for more details about this article) |
7/55. pheochromocytoma presenting after cardiac transplantation for dilated cardiomyopathy.pheochromocytoma may present with a clinical picture indistinguishable from that of idiopathic dilated cardiomyopathy. We report 2 such patients who underwent cardiac transplantation following which we diagnosed and successfully treated pheochromocytoma.- - - - - - - - - - ranking = 0.71428571428571keywords = cardiomyopathy (Clic here for more details about this article) |
8/55. Cerebrovascular event, dilated cardiomyopathy, and pheochromocytoma.cerebral infarction in children may be the result of various disease processes, including emboli from intracardiac sources, paradoxical emboli from the venous system, sickle cell disease, cyanotic heart disease, vasculitis affecting the carotid or cerebral vascular system, vascular anomalies, and prothrombotic states. We present a previously healthy adolescent who presented with the acute onset of hemiparesis. work-up revealed a dilated cardiomyopathy with a left ventricular mural thrombus as the etiology of his cerebrovascular event. Although dilated cardiomyopathy (DCM) may predispose to the development of a mural thrombus and subsequent embolic events, there are no previous reports in pediatric-aged patients of the development of an embolic event as the presenting manifestation of DCM. Further investigation of the etiology of the DCM led to the diagnosis of a pheochromocytoma. Congestive heart failure and DCM as the presenting sign of pheochromocytoma has likewise not been reported in a pediatric-aged patient. We review this unlikely sequence of events, the diagnostic evaluation of such patients, and treatment options.- - - - - - - - - - ranking = 0.85714285714286keywords = cardiomyopathy (Clic here for more details about this article) |
9/55. Reversal of catecholamine induced cardiomyopathy in a patient with bilateral malignant pheochromocytoma.A patient of catecholamine induced cardiomyopathy (CMP) due to bilateral malignant adrenal pheochromocytoma (PCC), successfully reversed on treatment is described here. To the best of our knowledge, this is first report of catecholamine induced CMP due to bilateral malignant adrenal PCC, which could be reversed after surgery.- - - - - - - - - - ranking = 0.71428571428571keywords = cardiomyopathy (Clic here for more details about this article) |
10/55. A rare cause of cardiogenic shock: catecholamine cardiomyopathy of pheochromocytoma.pheochromocytoma is a rare catecholamine secreting tumor that accounts for about 0.04% of cases of hypertension. Other less common cardiovascular manifestations such as arrhythmias, angina pectoris, acute myocardial infarction, dilated cardiomyopathy, acute heart failure, and cardiogenic shock have occasionally been reported. We describe the case of a 32-year-old previously healthy male patient who died of cardiogenic shock within 10 hours of admission. Postmortem examination showed a catecholamine cardiomyopathy and a pheochromocytoma of the right adrenal gland. pheochromocytoma with predominant epinephrine or dopamine secretion may take a hypotensive course. Sudden excessive catecholamine release can, as in the described case, cause cardiogenic shock.- - - - - - - - - - ranking = 0.85714285714286keywords = cardiomyopathy (Clic here for more details about this article) |
