Takotsubo Cardiomyopathy Associated with Chronic Psychiatric Stress in Major Depressive Disorder in an Elderly Patient

Takotsubo cardiomyopathy (TC) is a transient form of acute heart failure that most often occurs in postmenopausal women, typically triggered by a preceding emotional or physical stressor. A 74-year-old woman who suffered from chronic psychiatric stress visited National Medical Center for dyspnea. Acute emotional or physical stress could not be identified despite careful history taking. An electrocardiogram showed diffuse T-wave inversions with prolonged QT interval, and the echocardiogram showed akinesia of mid and apical segments of the left ventricle with hyperkinesia at the base. There was no significant stenosis on coronary angiography. Differing from the typical case of TC, which follows acute stress triggers, our case indicates that underlying chronic psychiatric illness exacerbation can lead to TC. We suggest that cardiologists and psychiatrists be aware of this predisposition to TC, especially in the circumstances of acute heart failure.

A Case of Klippel-Trenaunay Syndrome with Acute Submassive Pulmonary Thromboembolism Treated with Thrombolytic Therapy

Klippel-Trenaunay syndrome is a rare congenital mesodermal abnormality characterized by varicose veins, cutaneous hemangiomas, soft tissue and bony hypertrophy of limb. Potential complications such as deep venous thrombosis and pulmonary thromboembolism have not been reported in Korea to date. We demonstrate the case of a 48-year-old woman with Klippel-Trenaunay syndrome with extensive varicose veins on right lower limb, hypertrophy of left big toe and basilar artery tip aneurysm, complicated with acute submassive pulmonary thromboembolism treated successfully with intravenous thrombolytic therapy.

Atypical Stress Induced Cardiomyopathy During Endoscopic Sinus Surgery With Septoplasty in an Elderly Male Patient

Stress-induced cardiomyopathy, also known as Takotsubo cardiomyopathy, is caused by emotional or physical stressors and mimics acute myocardial infarction. Stress-induced cardiomyopathy is characterized by acute, reversible left ventricular apical ballooning without significant coronary artery stenosis. New variants of stress-induced cardiomyo pathy with localized wall motion abnormalities or an inverted pattern with a hyperdynamic apex have been reported. We present a rare case of a sudden cardiac arrest due to atypical stress-induced cardiomyopathy (mucosal packing and the injection of epinephrine) in an elderly male patient during elective endoscopic sinus surgery with septoplasty under local anesthesia. In this case, only the basal and midportions of the left ventricle were affected, whereas the apex was completely spared. The patient rapidly and completely recovered without sequelae.

Severe Resistant Hypertension Induced by Carbamazepine in an Elderly Patient

We report a case of a 73-year-old patient with a 17 year-history of well-controlled primary hypertension with a single antihypertensive drug, which became uncontrolled since 9 months ago when he started on oral carbamazepine (CBZ) therapy for syringomyelia. On admission, the patient had a blood pressure of 200-215/95-104mmHg despite an antihypertensive combination therapy with five different drugs. Further investigations ruled out secondary hypertension such as primary aldosteronism, pheochromocytoma and renal artery stenosis. After the discontinuation of CBZ, the blood pressure profile became significantly improved. The rechallenge with CBZ aggravated his blood pressure profile. Therefore, we considered that resistant hypertension was induced by the oral CBZ therapy.

Preoperative B-type Natriuretic Peptide as a Predictor of Postoperative Cardiac Events Following Orthopedic Elderly Patients

BACKGROUND: The aim of this study was to evaluate the value of preoperative plasma B-type natriuretic peptide (BNP) level in predicting postoperative in-hospital major adverse cardiac events (MACE, defined as atrial fibrillation, congestive heart failure, nonfatal myocardial infarction and cardiac death) in elderly patients undergoing orthopedic surgery. METHODS: Between March 2010 and September 2011, data from 156 patients (aged 65 years or older) who underwent scheduled or emergent orthopedic surgery, were investigated. Screening for postoperative in-hospital MACE was performed using clinical criteria. RESULTS: MACE occurred in 12 patients (7.7%). The BNP level was significantly higher in patients with MACE than in those without (median, 152.0; interquartile range [36.3 to 352.8] pg/mL vs. median, 36.8; interquartile range [15.5 to 98.1] pg/mL, p=0.005). The BNP level was positively correlated with the revised cardiac risk index score (r=0.300, p=0.001). In a receiver operating characteristic (ROC) analysis for MACE, the ROC for BNP was 0.746 (95% confidence interval, 0.602 to 0.891). At the optimal cut-off point (BNP=110 pg/mL), the sensitivity, specificity and positive and negative predictive values were 66.7, 81.2, 22.0% and 96.6%, respectively. On multivariate analysis, preoperative BNP was an independent predictor for MACE (odds ratio, 5.091; p=0.018) after adjusting for baseline confounding factors such as diabetes mellitus and history of cerebrovascular accident. CONCLUSION: The preoperative BNP level may be a useful tool in stratifying the risk for MACE in elderly patients undergoing orthopedic surgery.

A Case of Severe Coronary Spasm Associated with 5-Fluorouracil Chemotherapy

Cardiotoxicity associated with 5-fluorouracil (FU) is an uncommon, but potentially lethal, condition. The case of an 83-year-old man with colon cancer who developed chest pain during 5-FU infusion is presented. The electrocardiogram (ECG) showed pronounced ST elevation in the lateral leads, and the chest pain was resolved after infusion of nitroglycerin. A coronary angiogram (CAG) revealed that the patient had significant atherosclerosis in the proximal left circumflex artery. Coronary artery spasm with fixed stenosis was considered, and a drug-eluting stent was implanted. After 8 hours, the patient complained of recurring chest pain, paralleled by ST elevation on the ECG. The chest pain subsided after administration of intravenous nitroglycerin followed by sublingual nifedipine. Repeated CAG showed patency of the previous stent. This case supports the vasospastic hypothesis of 5-FU cardiac toxicity, indicating that a calcium channel blocker may be effective in the prevention or treatment of 5-FU cardiotoxicity.

Successful Resection of a Giant Left Ventricular Pseudoaneurysm Developed Later after Mitral Valve Replacement

We present a case of successful surgical resection of a giant left ventricular (LV) pseudoaneurysm that developed 5 yr after mitral valve replacement (MVR). A 59-yr-old female was admitted with exertional chest pain radiating to left arm and back. 64-slice multidetector computed tomography (MDCT) revealed significant stenosis on the ostium of the first diagonal branch of the left anterior descending coronary artery and also a huge pseudoaneurysm compressing the right atrium and the inferior vena cava. She underwent resection of the pseudoaneurysm, and the pseudoaneurysm tunnel was repaired from the inside of LV cavity by removing the previously inserted prosthetic valve, followed by redo MVR together with coronary arterial bypass grafting (CABG) for a single-vessel disease. At the 6-month follow-up, the patient continued to do well without any complications.

Acute Idiopathic Hemorrhagic Pericarditis with Cardiac Tamponade as the Initial Presentation of Acquired Immune Deficiency Syndrome

This paper presents a case of cardiac tamponade with idiopathic hemorrhagic pericarditis as the initial symptom of human immunodeficiency virus (HIV) infection. A 29-year-old male came to the emergency room with a sudden onset of dizziness. Upon arrival, he was hypotensive although not tachycardic, and his jugular venous pressure was not elevated. His chest X-rays revealed a mild cardiomegaly. Transthoracic echocardiography revealed a large amount of pericardial effusion with a diastolic collapse of the right ventricle, a dilated inferior vena cava with little change in respiration, and exaggerated respiratory variation of mitral inflow velocities, representing echocardiographic evidence of cardiac tamponade. After pericardiocentesis, his blood pressure improved to 110/70 mmHg without inotropics support. Serial 12-lead electrocardiograms during hospitalization revealed upwardly concave diffuse ST-segment elevation followed by a T-wave inversion suggestive of acute pericarditis. Pericardial fluid cytology and cultures for bacteria, mycobacteria, adenovirus, and fungus were all negative. HIV enzyme-linked immunosorbent assay (ELISA) was positive and confirmed by Western blot. The CD4 cell count was 168/mm3. Finally, the diagnosis of cardiac tamponade due to HIV-associated hemorrhagic pericarditis was made. It was concluded that HIV infection should be considered in the diagnosis of unexplained pericardial effusion or cardiac tamponade in Korea.

Hypereosinophilia Presenting as Eosinophilic Vasculitis and Multiple Peripheral Artery Occlusions without Organ Involvement

We report here a case with hypereosinophilia and peripheral artery occlusion. A 32-yr-old Korean woman presented to us with lower extremity swelling and pain. Angiography revealed that multiple lower extremity arteries were occlusive. The biopsy specimen showed perivascular and periadnexal dense eosinophilic infiltration in dermis and subcutaneous adipose tissue. Laboratory investigations revealed a persistent hypereosinophilia. She was prescribed prednisolone 60 mg daily. Her skin lesion and pain were improved and the eosinophil count was dramatically decreased. After discharge, eosinophil count gradually increased again. Cyanosis and pain of her fingers recurred. She had been treated with cyclophosphamide pulse therapy. Her eosinophilia was decreased, but the cyanosis and tingling sense were progressive. The extremity arterial stenoses were slightly progressed. Skin biopsy showed perivascular eosinophilic infiltration in the dermis and CD40 ligand (CD40L) positive eosinophilic infiltration. The serum TNF-alpha was markedly increased. These results suggest that CD40L (a member of TNF-alpha superfamily) could play a role in the inflammatory processes when eosinophil infiltration and activation are observed. We prescribed prednisolone, cyclophosphamide, clopidogrel, cilostazol, beraprost and nifedipine, and she was discharged.

Long-term clinical outcomes of newly implanted stents during intracoronary radiation / 대한내과학회지

BACKGROUND: New stent implantation during intracoronary brachytherapy is discouraged due to the high risk of late thrombosis. However, new stent implantation is inevitable in some cases due to the inadequate ballooning or major dissections. Long-term follow-up results of newly implanted stents during brachytherapy are not well-known. We performed this study to evaluate the long-term clinical outcomes of newly implanted stents during intracoronary brachytherapy. METHODS: In the Seoul national university Post-Angioplasty RhEnium irradiation (SPARE) trial, patients were treated with conventional catheter-based technique and then randomized to either beta- radiation (RG) or control group (CG). Radiation was performed with 188 -rhenium-filled conventional balloon catheter system. From 1999 to 2001, new stent implantation was performed in 58 and 56 patients in RG and CG, respectively. Clinical and angiographic follow up data were analyzed. RESULTS: In RG, short-term angiographic restenosis rate was lower than CG (28.6% vs 53%, p=0.03). In RG, late thrombosis was found in 3 patients. However, there was no late thrombosis in CG. Two year major cardiac event rates were not different between the 2 groups (RG: 25.9% vs CG: 28.3%). Independent predictors for major cardiac event in RG were major dissections (>or=type C) after stent implantation (beta=70, p=0.01) and longer administration of dual antiplatelets (aspirin+clopidogrel/ ticlopidine, >6 months, beta=0.07, p=0.04). CONCLUSION: Stenting during intracoronary brachytherapy seems to be ineffective in reducing long-term event rates. When new stent implantation is inevitable during brachytherapy, extreme attention is required not to make a dissection and long-term dual antiplatelet treatment should be followed after stent implantation.

Partial Anomalous Pulmonary Venous Return into Coronary Sinus with Intact Atrial Septum

We report a case of partial anomalous pulmonary venous return where the right upper and lower pulmonary veins drain into the coronary sinus with right-to-left shunt via patent foramen ovale. To our knowledge, this is the uncommon case where the interatrial septum is intact. The diagnosis was initially made by transthoracic echocardiography and transesophageal echocardiography with the infusion of agitated saline and confirmed by pulmonary artery angiography. Curative operation could not be performed because of the irreversible pulmonary hypertension.

A Case of Idiopathic Acute Myocarditis with Isolated Right Ventricular Failure

A 68 year-old woman was admitted due to chest pain with dyspnea. Transthoracic echocardiography showed isolated right ventricular dysfunction. Coronary angiogram was normal. Cardiac enzyme was elevated persistently. Under the supposed diagnosis of acute idiopathic myocarditis, she was treated with supportive care but symptom and cardiac enzyme was not improved. After steroid pulse therapy, symptom was improved and cardiac enzyme was normalized. She was discharged with improvement of symptoms.
