Intrapericardial Haematoma: A Rare Cause of Congestive Cardiac Failure After Three Years of Coronary Artery Bypass Grafting

Right Heart Failure as an Atypical Presentation of Chronic Type A Aortic Dissection - Multimodality Imaging for Accurate Diagnosis and Treatment. A case report and mini-review of literature

Background

An intrapericardial organized haematoma secondary to chronic type A aortic dissection is an extremely rare cause of right heart failure. Imaging studies are essential in recognising and diagnosis of this distinctive medical condition and guiding the anticipated treatment.

Case presentation

A 70-year-old male patient was admitted for progressive symptoms of right heart failure. His cardiovascular history exposed an aortic valve replacement 22 years before with a Medtronic Hall 23 tilting valve with no regular follow-up. Classical signs of congestion were recognized at physical examination. Transthoracic two-dimensional echocardiography and thoraco-abdominal computed tomography angiography, as essential parts of multimodality imaging algorithm, established the underlying cause of right heart failure. Under total cardiopulmonary bypass and cardiac arrest, surgical removal of the haematoma and proximal repair of the ascending aorta with a patient-matched vascular graft were successfully performed. The patient was discharged in good condition with appropriate pharmacological treatment, guideline-directed; no imagistic signs of acute post-surgery complications were ascertained.

Conclusion

This paper highlights the importance of recognizing and providing a timely clinical and imagistic diagnosis of this very rare, potentially avoidable cause of right heart failure in patients with previous cardiac surgery.

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.

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.
