Chronic Expanding Intrapericardial Hematoma After Pericardial Paracentesis

A Rare Case of Chronic Expanding Intrapericardial Hematoma with Refractory Right-sided Heart Failure 30 Years after the Surgical Repair of Tetralogy of Fallot

We herein report the case of a 79-year-old man who presented with right-sided heart failure (HF) 27 years after undergoing surgery for tetralogy of Fallot. The HF did not respond well to oral diuretics. Transthoracic echocardiography and chest X-ray failed to determine the cause of the HF for three years. An intrapericardial mass located just behind the sternum, was finally identified on computed tomography. The mass had compressed the right ventricle, causing right-sided HF. Pre-surgical diagnostic images led to suspicion of a chronic expanding intrapericardial hematoma (CEIH), and the CEIH was surgically removed. The patient's symptoms improved markedly.

A rare case of idiopathic chronic expanding pericardial hematoma presenting as pericardial tamponade: a case report and literature review

Chronic expanding pericardial hematoma is a very rare disease that occurs after open-heart surgery. We report successful surgical treatment of a rare case of chronic expanding pericardial hematoma that developed into a large mass and presented as pericardial tamponade without apparent cause. An 82-year-old woman with no history of cardiac surgery, chest trauma, or epicardial injury presented with a 3-year history of progressive exertional dyspnea. Surgical resection of the mass via midsternotomy was planned to release the cardiac symptoms and to confirm the diagnosis of chronic expanding pericardial hematoma.

Successful surgical case of refractory chronic expanding intrapericardial hematoma treated with preoperative coil embolization of the feeding vessels

Complete surgical resection of chronic expanding intrapericardial hematoma was often difficult because of the severe adhesion. Preoperative coil embolization of the feeding vessels can prevent recurrent expanding of the residual hematoma and would achieve good results.

A rare presentation of intrapericardial hematoma 20 months post aortic valve replacement

We report the successful treatment of a rare case of chronic intrapericardial hematoma which presented with congestive cardiac failure 20 months after aortic valve replacement surgery for severe calcific aortic stenosis. Chest roentgenograph demonstrated paracardiac mass over lower left ventricle border, left pleural effusion and pulmonary venous hypertension. An echocardiographic study demonstrated intrapericardial mass posterolateral to left ventricle compressing left ventricular cavity both during systole and diastole causing septum to bulge into right ventricle. Computed tomography showed a loculated pericardial mass in left heart margin, left pleural effusion, bilateral axillary and mediastinal lymphadenopathy. Surgical resection was planned to relieve the symptoms and to confirm the diagnosis of the mass. The mass was completely resected through left anterolateral thoracotomy and histopathology findings confirmed the diagnosis of hematoma with cystic degeneration. Postoperative course was uneventful, and his symptoms improved markedly.
