    We report a case of two babies with absence of pericardium and patent ductus arteriosus (PDA). The absence of pericardium was found coincidentally during PDA ligation. The PDA was successfully ligated but the pericardium was not reconstructed. Postoperatively, the agenesis of the pericardium did not interfere with cardiac function.

    This paper discusses the feasibility of using a free pericardial patch in repairing defects of the esophagus. The experimental model used is the dog. A piece of the side wall of the esophagus is first excised. This defect in the esophagus is then covered
    with a free patch of pericardium. The animals are then sacrificed at sequential dates and the grafted site submitted for microscopic examination. The results show that a free graft of pericardium when used as a patch can prevent leakage of esophageal contents and allow healing of the defect without gross narrowing of the lumen.

    This study investigates the effect of preservation methods on the performance of bovine parietal pericardium grafts in a rat model. Mid-ventral full thickness abdominal wall defects of 3 x 2.5 cm in size were created in 90 male Sprague-Dawley rats (300-400 g), which were divided into three groups of 30 rats each. The abdominal defects of group one and two were repaired with lyophilized and glycerolized bovine pericardium grafts, while the defects of group three were repaired with expanded polytetrafluoroethylene (ePTFE) Mycro Mesh as a positive control. Another group of 30 rats underwent sham operation and was used for comparison as negative control. Each group of rats (n = 30) was divided into five subgroups (n = 6) and killed at 1, 3, 6, 9 and 18 weeks post-surgery for gross and morphological evaluations. The rats tolerated the surgical procedure well with a total mortality of 0.05%. No serious post-operative clinical complications or signs of rejection were encountered. Adhesions between the grafts and the underlying visceral organs observed in the study were mostly results of post-surgical complications. Glycerol preservation delayed degradation and replacement of the grafts, whereas lyophilization caused early resorption and replacement of the grafts. The glycerolized grafts were replaced with thick dense fibrous tissue, and the lyophilized grafts were replaced with thin loose fibrous tissue. The healing characteristic of the bovine pericardium grafts was similar to those of the sham-operated group, and quite different from those of the ePTFE Mycro Mesh. The outcome of the present study confirmed the superiority of glycerolized bovine pericardium grafts over its lyophilized counter part.

    Mediastinal nonseminomatous germ cell tumor (NSGCT) is rare. NSGCT shows excellent response to cisplatin-based chemotherapy. However, some tumors continue to enlarge despite normal tumor markers after chemotherapy, a rare condition called growing teratoma syndrome (GTS). Recognition of this condition is imperative for prompt surgical resection to prevent further cardiopulmonary compression and to improve survival. Multidisciplinary team meeting is important for perioperative preparation and care to improve the outcome of this high-risk surgery. Here, we report two cases of mediastinal GTS and underwent surgical resection, of which one died of pericardial decompression syndrome and the other is well.

    The normal pericardium is a fibroelastic sac containing a thin layer of fluid that surrounds the heart. Cardiac tamponade, which may be acute or subacute, is characterized by the accumulation of pericardial fluid under pressure. Tuberculous pericarditis is a complication of tuberculosis which is often diagnose late due to the difficulty in establishing this diagnosis. We present a case of pericardial tuberculosis diagnosed in a 20-year-old young retroviral disease patient who presented with signs of cardiac tamponade. His clinical condition improved post-pericardial tapping and he was discharged with anti tuberculosis medications. This case highlight the importance of having a high level of suspicion as this condition is easily curable.

    The aim of this study was to evaluate bovine pericardium surgical patch in rat model. Bovine pericardial sacs collected from local abattoir were cleaned, disinfected and cut into pieces of 3 by 2.5cm and preserved in 99.5% glycerol. Full thickness abdominal wall defects of 3 by 2.5 cm were created in 30 adult male Sprague Dawley rats and repaired with glycerol preserved pieces. The rats were serially sacrificed in a group of six rats at 1,3,6,9 and 18 weeks post-surgical intervals for morphological and tensometeric study. Macroscopically, no mortality or postoperative surgical complications was encountered except slight adhesions between implanted grafts and some visceral organs in 10% of the rats. Microscopically no calcification or foreign body giant cell formation was found in the explanted grafts. The implanted grafts were replaced gradually with recipient tissue, which made mainly of dense collagenous bundles. The healing strength between the implanted grafts and the recipient abdominal wall was gradually increased with time. The results of this study showed that glycerol preserved bovine pericardium act as scaffold for transformation into living tissue without clinical complications such as that associated with prostheses.

    In the fabrication of a bioprosthetic heart valve from bovine pericardial tissues, the tissues are subjected to suturing. The stress-strain response of sutured as well as unsutured strips of this tissue were examined. The stress-strain response was determined using a tensile-testing machine. It was found that suturing weakens the tissue in that sutured strips are more extensible, exhibit a lower stress at rupture and a lower final elastic modulus. In addition, it was also found that the bigger the suture/needle size used the greater the decrease in tissue strength. In all, tissue strength was observed to decrease by 22 to 59% in this study. The weakening of the tissue is attributed to the puncture holes created by the surgeon's needle which create regions of weakness. This response of bovine pericardial tissue to suturing should be given due consideration in the fabrication of a bioprosthetic heart valve using this tissue.

    A 72-year-old Chinese man presented with mild symptoms of heart failure. Transthoracic echocardiography showed signs of cardiac tamponade though clinically he was relatively well. The option of pericardiocentesis was not carried out due to a narrow window for aspiration with only a thin layer of effusion seen surrounding the apex and right ventricle on subcostal view.Pericardial window was done via a left anterolateral thoracotomy. Intraoperatively, 500 cm3 of purulent fluid was drained. Microbiology screens were all negative. We present the atypical clinical course of this elderly man presenting with a large pyopericardium.

    Liposarcoma is regarded as the second most common soft tissue malignant tumour. Metastasis of liposarcoma to the heart is very rare, and to date, less than 40 cases have been reported in the literature. We report a 46 year-old male with myxoid liposarcoma of the lower extremity who developed extensive metastasis to the left ventricle, pulmonary artery, and pericardium. The patient presented with acute symptoms of dyspnea 16 years after surgical resection of the primary tumour, and his dyspnea progressed to cardio-respiratory arrest within the first few days of hospital admission.

    Congenital absence of the pericardium is a rare condition,which is frequently missed due its subtle presentation. It may be misdiagnosed as another condition causing right heart dilatation such as an intracardiac shunt. We report the finding of diastolic pressure alternans during cardiac catheterization in this single case report of a patient with congenital total absence of the pericardium. The occurrence of this phenomenon is hypothesized to be due to excessive cardiac hypermobility and paradoxical septal movement. We propose that this finding may be a useful clue to the diagnosis.

    Constrictive pericarditis is a disabling disease of the heart, which causes cardiac diastolic dysfunction. We present a case of a 44-year-old gentleman with a history of blunt chest trauma who presented with constrictive pericarditis with right-sided heart failure. Imaging studies revealed a calcified pericardium. He underwent an uneventful pericardiectomy. Calcification is common yet rare if it involves the pericardium. It normally occurs following fibrosis and adhesion which are associated with the chronicity of the disease, hence creating more challenge to the operating surgeon in the pericardiectomy procedure.

    Methicillin-resistant Staphylococcus aureus (MRSA) purulent pericarditis, characterised by frank pus collection or microscopic pyogenic effusion in the pericardium represents the most serious form of pericardial infection. The route of MRSA acquisition in pericardial abscess commonly occurs via the blood stream infection and it is more commonly observed among immunocompromised individuals. To date, diabetic foot ulcer infection rarely disseminates and becomes a nidus for pericardial infection. Herein, we report an unusual case of MRSA pericardial abscess in a 44-year-old man who presented at Hospital Seri Manjung, Malaysia with cardiac tamponade. Past medical history indicated that he was recently treated for infected diabetic foot ulcer with MRSA bacteraemia one week earlier. Despite adequate pericardial drainage and extended parenteral vancomycin therapy, this case ended in fatality on day 42 of admission due to nosocomial infection. It is hoped that this report serves to increase the vigilance among clinicians that diabetic foot ulcer infections have the potential to progress to pericardial abscess in the presence of MRSA bacteraemia, although they may appear seemingly innocuous at presentation. Systemic vancomycin must be instituted promptly when MRSA bacteraemia is confirmed in order to circumvent the propagation of MRSA.

    Corneal perforation is an ocular emergency that requires early intervention to avoid permanent visual loss from endophthalmitis or irreversible structural changes. Although tectonic keratoplasty is the best choice for patching a large perforation, a donor cornea is not always immediately available. Consequently, an alternative material is required while awaiting a donor cornea. We report the use of preserved bovine pericardium as a temporizing graft to maintain the ocular integrity in two patients with corneal perforation.

    Type IIIa mitral regurgitation (MR) due to rheumatic leaflet restriction often renders valve repair challenging and may predict a less successful repair. However, the utilization of leaflet mobilization and extension with the pericardium to increase the surface of coaptation may achieve satisfactory results. We reviewed our experience with leaflet extension in rheumatic mitral repair with emphasis on the technique and mid-term results.

    A 16-year-old student presented with a 4-week history of progressive shortness of breath, loss of appetite, and occasional blood-tinged sputum. The chest X-ray revealed massive right-sided pleural effusion with cardiomegaly. An echocardiogram revealed a large pericardial mass with massive pericardial effusion. Subsequent computed tomography of the thorax revealed a large heterogeneous mass in the right lung with extension into the pericardium. Lung biopsy revealed primitive neuroectodermal tumor (PNET) with small round blue cells, Homer-Wright rosettes, and CD99 positivity. We discuss pericardial metastases of PNET and its implication in this patient.

    To describe use of a locally processed bovine pericardium (BP) to cover a large central corneal perforation following alkali injury and discuss postoperative outcome. A 27-year-old Malay male patient presented two weeks after alkali splashed in his left eye while working. A clinical diagnosis of left central corneal ulcer with limbal ischemia following alkali injury with secondary infection was made. After failed medical therapy, we performed a Gunderson conjunctival flap under local anesthesia that retracted after one week and resulted in a large central corneal perforation with surrounding stromal thinning. The perforation was covered with a locally processed BP xenograft (Lyolemb) supplied by the National Tissue Bank, University Sains Malaysia. Nine months follow-up showed a well-taken graft without any exposure/dehiscence and minimal inflammation. Amniotic membrane transplantation when used as a patch graft needs an urgent tectonic graft to promote corneal stability in patients with severe corneal thinning. The use of processed BP can be a viable option in treating such cases.

    A study was conducted to investigate the effectiveness of freeze-dried bovine pericardium (FDBP) as a biomaterial in diaphragmatic herniorrhapy in dogs. Eight adult dogs were randomly selected and divided into two equal groups. In FDBP group, a diaphragmatic defect was induced and repaired with an identical size of FDBP. In the control group, a diaphragmatic wall was incised at three-side border creating a flap and sutured. Grossly, only mild intrathoracic adhesion was observed for most of the animals, and no herniation occured. Microscopically, the biomaterial incorporated into the host's tissue by ingrowth of young muscle fiber and massive new blood vessel formation in between the fibrous tissue.

    BACKGROUND: Pericardial effusion is a known complication of post-open cardiac surgery which can progress to life-threatening cardiac tamponade. Classical signs of tamponade such as hypotension and pulsus paradoxus are often absent. Diagnosing acute cardiac tamponade with transthoracic echocardiography (TTE) can be challenging in post-cardiac surgical patients due to distorted anatomy and limited scanning windows by the presence of surgical dressings or scar. Additionally, this patient population is more likely to have a loculated pericardial effusion, or an effusion that is isoechoic in appearance secondary to clotted blood. These findings can be challenging to visualize with traditional TTE. Missed diagnosis of cardiac tamponade due to loculated pericardial clot can result in delayed diagnosis and clinical management.

    CASE PRESENTATION: We report a case series that illustrates the diagnostic challenge and value of resuscitative transesophageal echocardiography (TEE) in the emergency department (ED) for the diagnosis of cardiac tamponade due to posterior loculated pericardial clot in post-surgical coronary artery bypass graft (CABG) patients.

    CONCLUSIONS: Cardiac tamponade due to loculated posterior pericardial clot post-CABG requires prompt diagnosis and appropriate management to avoid the potential for hemodynamic instability. Transesophageal echocardiography allows a rapid diagnosis, early appropriate referral and an opportunity to institute appropriate therapeutic measures.
