Clinical presentation, diagnostic evaluation, and management of undifferentiated/unclassified cardiac sarcoma: A case report and literature review.

This case report details a challenging instance of undifferentiated/unclassified cardiac sarcoma in a 28-year-old female, presenting with diverse symptoms like muscle weakness, shortness of breath, and hemoptysis. Diagnostic hurdles led to an initial misdiagnosis of granulomatosis with polyangiitis before discovering a sizable left atrial mass, ultimately diagnosed as high-grade undifferentiated/unclassified sarcoma. Despite initial surgical intervention, the patient's condition worsened, underscoring the complexities in managing such cases involving cardiac sarcomas. This case emphasizes the diagnostic complexities associated with primary cardiac sarcomas, particularly the challenges in achieving accurate diagnoses and formulating effective treatment strategies.

Potentially fatal atrium perforation due to right jugular vein catheterization recognized by venography: A case report.

Central venous catheters are the prevalent path for dialysis. Our case was a 54-years-old male with a new case of end-stage renal disease with a complaint of right jugular hemodialysis catheter dysfunction. In our case, the early dysfunctional catheter should be evaluated with contrast studies to achieve accurate information.

Successful liver and kidneys transplant following aortic dissection and subclavian artery rupture: A case report.

INTRODUCTION AND IMPORTANCE: Despite the increasing number of liver and kidney transplants, the number of patients awaiting for a proper donor is still exceeding. Therefore, the preservation of donor organs is critically advocated. CASE PRESENTATION: Herein, we presented a successful liver and kidney transplant from a brain-dead donor who was found preoperatively to have simultaneous aortic dissection and intramural hematoma and additionally developed left subclavian artery dissection and perforation, which was noticed following sternotomy. CLINICAL DISCUSSION: This case experience highlights the key role of cardiac surgeons in preserving visceral organs by rapid repair of the dissection and perforation sites of the aorta and its branches which culminate in lifesaving organ donation. CONCLUSION: This case report introduces the first case of a successful; liver and kidneys transplant in a patient with concurrent aortic dissection and subclavian artery rupture which served as a lifesaving donor.

Whole-organ decellularization of the human uterus and in vivo application of the bio-scaffolds in animal models.

PURPOSE: The aim of this investigation was to design a perfusion-based decellularization protocol to provide whole human uterine bio-scaffolds with preserved structural and componential characteristics and to investigate the in vivo properties of the decellularized tissues. METHODS: Eight human uteri, donated by brain-dead patients, were decellularized by perfusion of sodium dodecyl sulfate (SDS) through the uterine arteries using a peristaltic pump. The bio-scaffolds were evaluated and compared with native human uterus regarding histological, immunohistochemical, structural, and bio-mechanical properties, in addition to CT angiographies to examine the preservation of the vascular networks. Subsequently, we obtained acellular patches and implanted them on uterine defects of female Wistar rats to investigate the bio-compatibility and regenerative potential of the bio-scaffolds. Finally, we performed immunostaining to investigate the potential role of circulating stem cells in recellularization of the implanted bio-scaffolds. RESULTS: The outcomes of this investigation confirmed the efficacy of the proposed protocol to provide whole human uterine scaffolds with characteristics and extra-cellular matrix components similar to the native human uterus. Subsequent in vivo studies demonstrated the bio-compatibility and the regenerative potential of the scaffolds and suggested a signaling pathway as an underlying mechanism for the regenerative process. CONCLUSIONS: To the best of our knowledge, this investigation provides the first efficient perfusion-based decellularization protocol for the human uterus to obtain whole-organ scaffolds. The outcomes of this investigation could be employed in future human uterus tissue engineering studies which could ultimately result in the development of novel treatments for female infertile patients.

A case report of an extremely rare type of cardiac tumor: Primary cardiac angiofibroma.

Cardiac angiofibroma is a very rare diagnosis when a patient develops an intracardiac mass. It is a primary benign cardiac tumor with a scarcity of information in the literature. This case report illustrates a 26-year-old man with a complaint of chronic chest tightness who was first diagnosed with right ventricle tumor by echocardiography then underwent cardiac magnetic resonance imaging (CMR) which confirmed the presence of a highly-vascular tumor with radiologically benign behavior. Then his tumor was excised, his postoperative course was uncomplicated and he was well within almost 2 months after discharge. Ultimately the histopathologic findings demonstrated vascular and stromal tissue in favor of angiofibroma and excluded the other diagnoses with immunohistochemical and trichrome staining. Angiofibroma is a benign, highly vascular tumor, mostly discovered in the nasopharynx. When it is found in the heart, CMR and pathology are pivotal to rule in its diagnosis. It is isointense in T1 weighted and hyperintense in T2 weighted sequences with intense enhancement following contrast injection. Its pathology contains an admixture of vasculatures with CD31 positive immunoreactivity for endothelial cells and fibrotic tissue with bluish coloration in trichrome staining. Eventually, its treatment includes merely surgical excision given its benign nature.

Role of chest CT scan in atypical cardiac trauma management: Left ventricle injury by a nail gun.

We report a case of an accidental penetrating cardiac trauma with a nail gun. A 28-year-old man was repairing a sofa with a nail gun when a nail was misfired to his chest. At the time of his presentation, he underwent chest CT scan, showing the nail as a sharp hyperdense foreign body penetrating the chest wall passing through the lower lobe of the left lung and finally the anterior aspect of left ventricle cavity. This report highlights the utility of the chest CT scan to detect trajectory of the misfired nail accurately and instantaneously in a hemodynamically stable patient to assist in the surgery plan.

A rare case of cardiac metastasis from uterine cervical adenocarcinoma.

Metastatic cardiac tumors are rare and are usually from lung, breast, and esophageal cancers. Although uterine cervical cancer is relatively common, its metastasis to the heart is extremely rare. Herein, we report an unusual case of metastatic cervical adenocarcinoma to the heart presenting with a huge right atrial mass and tamponade. The cardiac mass was surgically resected and pathologic study with immunohistochemistry staining confirmed the diagnosis. .
