Large Lipomatous Hypertrophy of the Interventricular Septum

We present the case of a 58-year-old woman who had large lipomatous hypertrophy of the interventricular septum, a condition that is reported very infrequently. Preoperative cardiac magnetic resonance images revealed an inhomogeneous, infiltrating mass that was suppressed in fat-suppression mode. The extensive mass was causing right ventricular dysfunction, so we excised it through a right ventricular approach. The findings on histologic analysis of the mass were consistent with lipomatous hypertrophy. The patient died of septic shock on the 28th postoperative day. In addition to the patient''s case, we discuss the characteristics and diagnosis of this rare entity.     

Conservative Management of Cardiac Hemangioma for 11 Years

Cardiac hemangiomas are benign tumors with an unpredictable natural history. Surgical resection is the treatment of choice; however, conservative management can be an alternative in some patients.We report a case of a left-sided cardiac hemangioma that we managed conservatively for 11 years without obvious major complications in the patient, an adult woman.     

Resolution of Right-Sided Heart Failure Symptoms after Resection of a Primary Ovarian Carcinoid Tumor

Carcinoid tumors are rare neuroendocrine malignancies that typically originate from the gastrointestinal tract. Patients who are diagnosed with carcinoid heart disease generally have poor prognoses because of advanced metastases during staging and few therapeutic options. We present the case of a 61-year-old woman with right-sided heart failure, secondary to carcinoid heart disease caused by a primary ovarian carcinoid tumor. After undergoing surgical resection of the left ovary and fallopian tube, the patient experienced complete resolution of her heart failure symptoms. In addition to the patient''s case, we discuss the diagnosis, nature, and treatment of this rare condition.     

Cardiac Sarcoidosis Presenting as Constrictive Pericarditis

In patients with cardiac sarcoidosis, the sarcoid granulomas usually involve the myocardium or endocardium. The disease typically presents as heart failure with ventricular arrhythmias, conduction disturbances, or both. Constrictive pericarditis has rarely been described in patients with sarcoidosis: we found only 2 reports of this association.We report the case of a 57-year-old man who presented with clinical and hemodynamic features of constrictive pericarditis, of unclear cause. He was admitted for treatment of recurrent pleural effusion. After a complicated hospital course, he underwent pericardiectomy. His clinical and hemodynamic conditions improved substantially, and he was discharged from the hospital in good condition. The pathologic findings, the patient''s clinical course, and his response to pericardiectomy led to our diagnosis of cardiac sarcoidosis presenting as constrictive pericarditis. In addition to the patient''s case, we discuss the nature and diagnostic challenges of cardiac sarcoidosis. Increased awareness of this disease is necessary for its early detection, appropriate management, and potential cure.     

Prompt Recognition of Left Ventricular Free-Wall Rupture Aided by the Use of Contrast Echocardiography

In the modern period of reperfusion, left ventricular free-wall rupture occurs in less than 1% of myocardial infarctions. Typically, acute left ventricular free-wall rupture leads to sudden death from immediate cardiac tamponade. We present the case of a 59-year-old woman who sustained a posterior-wall myocardial infarction and subsequent cardiac arrest with pulseless electrical activity. A bedside transthoracic echocardiogram showed pericardial effusion with cardiac tamponade. Emergency pericardiocentesis yielded 500 mL of blood, and spontaneous circulation returned. Contrast-enhanced echocardiograms revealed inferolateral akinesis and a new, small myocardial slit with systolic extrusion of contrast medium, consistent with left ventricular free-wall rupture. During immediate open-heart surgery, a small hole in an area of necrotic tissue was discovered and repaired. This case highlights the usefulness of bedside contrast-enhanced echocardiography in confirming acute left ventricular free-wall rupture and enabling rapid surgical treatment.     

Benefits and Limitations of Multimodality Imaging in the Diagnosis of a Primary Cardiac Lymphoma

Primary cardiac tumors are far rarer than tumors metastatic to the heart. Angiosarcoma is the primary cardiac neoplasm most frequently detected; lymphomas constitute only 1% of primary cardiac tumors.We present the case of a 55-year-old woman with a recently diagnosed intracardiac mass who was referred to our institution for consideration of urgent orthotopic heart transplantation. Initial images suggested an angiosarcoma; however, a biopsy specimen of the mass was diagnostic for diffuse large B-cell lymphoma. The patient underwent chemotherapy rather than surgery, and she was asymptomatic 34 months later.We use our patient''s case to discuss the benefits and limitations of multiple imaging methods in the evaluation of cardiac masses. Certain features revealed by computed tomography, cardiac magnetic resonance, and positron emission tomography can suggest a diagnosis of angiosarcoma rather than lymphoma. Cardiac magnetic resonance and positron emission tomography enable reliable distinction between benign and malignant tumors; however, the characteristics of different malignant tumors can overlap. Despite the great usefulness of multiple imaging methods for timely diagnosis, defining the extent of spread and the hemodynamic impact, and monitoring responses to treatment, we think that biopsy analysis is still warranted in order to obtain a correct histologic diagnosis in cases of suspected malignant cardiac tumors.     

肝硬变腹水患者钾钠氯及酸碱失衡

目的研究肝硬变腹水患者的钾、钠、氯及酸碱失衡。方法肝硬变腹水患者１５４例，血Ｋ＋、Ｎａ＋、Ｃｌ－测定采用ＥＥＬ公司自动分析仪及火焰光度计。血气及酸碱度测定采用ＩＬ１３０２型自动微机分析仪。结果低血钾者５７例，高血钾者６例，低血钠者８１例，高血钠者１２例，低血氯者３４例，高血氯者８例。２４例血气及酸碱度测定结果显示，以碱中毒者为主。依次为呼碱、呼碱＋代酸、代酸、代碱、呼酸。本组高血钾、低血钠与Ｃｈｉｌｄ分级、ＢＵＮ、Ｃｒ值相关。从本组资料表明，重症肝硬变腹水患者水盐代谢失衡多为医源性所致，且加重原有失衡。高钾血症、急性低钠血症及高钠血症大多如此，多为住院后发生，常可危及生命。结论肝硬变腹水患者的高钾血症、低钠血症和高钠血症大多在肝肾功能低下，不适当的治疗所致，是影响预后的重要因素     

Primary Cardiac Sarcoidosis with Syncope and Refractory Atrial Arrhythmia: A Case Report and Review of the Literature

We discuss the case of a 38-year-old black man who presented at our hospital with his first episode of syncope, recently developed atrial arrhythmias refractory to pharmacologic therapy, and a left atrial thrombus. He was diagnosed with primary cardiac sarcoidosis characterized by predominant involvement of the epicardium that caused atrial fibrillation and atrial flutter. Histologic analysis of his epicardial lesions yielded a diagnosis of sarcoidosis. This patient''s atrial arrhythmia was successfully treated with a hybrid operation that involved resection of his atrial appendage, an Epicor maze procedure, and radiofrequency ablation during a catheter-based electrophysiologic study. The cardiac sarcoidosis was successfully managed with corticosteroid therapy.Our case report shows that sarcoidosis can initially manifest itself as syncope with new-onset atrial arrhythmia. Sarcoidosis is important in the differential diagnosis because of its progressive nature and its potential for treatment with pharmacologic, surgical, and catheter-based interventions.     

Acute Coronary Thrombosis and Multiple Coronary Aneurysms in a 22-Year-Old Man with the Human Immunodeficiency Virus

The human immunodeficiency virus (HIV) can cause diverse cardiovascular complications. In HIV patients on antiretroviral therapy, the prevalence of myocardial infarction has steadily increased over the years. Young patients who are naïve to antiretroviral therapy and who experience coronary events are not well represented in the medical literature. We describe the case of a 22-year-old man, infected with HIV for 4 years and never treated with antiretroviral therapy, who emergently presented with a non-ST-segment-elevation myocardial infarction. Coronary angiograms revealed thrombosis and multiple coronary artery aneurysms; however, no areas of atherosclerotic stenosis were apparent. He was successfully treated with coronary stenting, antiplatelet therapy, and anticoagulation. Nine months after the initial presentation, he exhibited excellent exercise capacity, and no ischemia was evident. We discuss the various therapeutic approaches in this case.
