This abstract presents the case of a 37-year-old female with no significant past medical history who presented to the emergency department with a unique and challenging clinical scenario. The patient complained of chest pain, dyspnea, and a productive cough associated with stabbing chest pain that improved with leaning forward for the past week. Despite an initial diagnosis of community-acquired pneumonia, the patient's condition deteriorated rapidly, leading to septic shock. Blood cultures ultimately revealed Streptococcus pneumoniae as the causative organism. Subsequent imaging and diagnostic procedures demonstrated a complex clinical course, including loculated pleural and pericardial effusions. The patient's condition necessitated multiple interventions, including pericardiocentesis, chest tube placement, and intracavitary lytic therapies, in addition to intubation for acute respiratory failure. The case further evolved with the development of a pericardial abscess, successfully managed with surgical drainage and a partial pericardiectomy. The patient eventually showed significant clinical improvement and was discharged on a targeted antibiotic regimen. This case highlights the importance of vigilance in identifying rare complications of pneumonia and the need for prompt, multidisciplinary management to ensure the best possible outcome for the patient. Long-term follow-up was recommended to assess the patient's recovery. This case underscores the complexities and challenges of managing uncommon presentations of infectious diseases and emphasizes the value of a comprehensive, multidisciplinary approach in such cases., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2023, Sabanci et al.)

Mechanical prosthetic valve thrombosis (PVT) is a serious condition that is associated with various life-threatening complications. The utilization of multimodality imaging techniques is critical in identifying this etiology. Its management is complex and often requires repeat surgical valve replacements. Our report describes the case of a 48-year-old female who presented with mechanical mitral valve thrombosis in the setting of subtherapeutic anticoagulation. Due to her complex surgical history, nonsurgical therapeutic options were initially pursued for management. Through shared decision-making and after exhaustion of other alternatives, she was maintained on optimized medical therapy and was scheduled for repeat elective surgery. After compliance with medical therapy and close monitoring, she improved significantly, and her underlying pathology completely resolved, eliminating the need for surgery. This report indicates that the management of mechanical prosthetic valve thrombosis should be individualized and emphasizes the importance of involving a multidisciplinary team of medical and surgical professionals to achieve the best clinical outcomes., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2023, Saeed Al-Asad et al.)

Masson's tumor is a benign tumor that usually arises secondary to vascular trauma or thrombi, leading to vascular proliferation. Masson's tumors are most commonly reported in the head, neck, and extremities. Cases in the heart are exceedingly rare, with most case reports describing the left atrium as the most common location. Even though the tumor is benign, excision is recommended due to the risk of embolization. This is a case of Masson's tumor located in the left ventricle. The patient is a 24-year-old female, who presented complaining of palpitations and lightheadedness. Transthoracic echocardiography showed a mobile echodensity in the left ventricle. Cardiac MRI showed characteristics similar to a myxoma. The patient underwent surgical resection and a biopsy showed Masson's tumor. This case report focuses on the histopathological features and imaging findings of Masson's tumor., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2023, Panama et al.)

A 75-year-old male, with a past medical history of chronic kidney disease stage 3 (CKD3) and a recent diagnosis of bilateral hydronephrosis and Foley catheter placement, presented to the emergency department for fever. Blood cultures grew Aerococcus urinae. Transthoracic echo (TTE) demonstrated thickened aortic valve leaflets with perforation, multiple echo densities, and severe aortic regurgitation. The patient developed decompensated congestive heart failure and cardiogenic shock. En route to surgery for emergent aortic valve replacement, the patient lost pulse and was resuscitated. The patient was subsequently transferred to the ICU where the family decided to initiate comfort care measures. This case highlights the importance and necessity of the prompt diagnosis and treatment of infective endocarditis and makes the reader aware of uncommon and rare organisms, such as Aerococcus urinae, as potential etiologies., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2022, Saeed Al-Asad et al.)
