ABSTRACT
The 2 primary components of valvular heart disease are mitral regurgitation (MR) and tricuspid regurgitation (TR). Transcatheter edge-to-edge repair (TEER) is an advanced, minimally invasive procedure that has recently displayed encouraging outcomes in the treatment of these pathologies. TEER offers a nonsurgical alternative for individuals diagnosed with conditions deemed to be high-risk surgical candidates. Currently, the TEER procedure employs devices such as MitraCLIP and TriCLIP, as well as innovative PASCAL (transcatheter valve repair system used for mitral and tricuspid valve repair) and FORMA (repair system used for tricuspid valve repair) repair systems. In the COAPT (Cardiovascular Outcomes Assessment of the MitraClip Percutaneous Therapy for Heart Failure Patients with Functional Mitral Regurgitation) trial enrolling 614 patients to test the efficacy of TEER in MR, a significant reduction in hospitalization due to heart failure was observed at 24 months in the MitraClip + guideline-directed medical therapy (GDMT) group (35.8%) than in the GDMT-alone group (67.9%), HR, 0.53; P < 0.001, lower rate of all-cause mortality at 29.1% compared with 46.1% (P < 0.001), lower risk of cerebrovascular events (P = 0.001), and lower mortality due to cardiovascular events (P < 0.001). In another trial, patients with moderate TR or greater than New York Heart Association Class II or higher underwent TEER using the TriClip for the management of TR. The outcomes were encouraging, with 86% of patients showing a reduction in TR severity of at least one grade. As the technology and research surrounding TEER continue to progress, a more extensive range of patients are expected to qualify for TEER procedures. Our comprehensive review sought to extensively explore the background, equipment used, effectiveness of MR and TR, potential side effects, future prospects, and ongoing trials associated with TEER. We further discuss the existing gender, racial, and socioeconomic disparities in the realm of TEER.
ABSTRACT
Key Clinical Message: A unique ER/PR-positive mucinous adenocarcinoma of breast but CK7/CK20 negativity. A rare finding of Lymphoplasmacytic Infiltration is noted. Successful treatment included modified radical mastectomy and tamoxifen-based therapy, leads to remission. Abstract: Mucinous carcinoma, which is characterized by the presence of abundant extracellular mucin, is a rare and distinctive subtype of invasive breast cancer. This subtype accounts for less than 5% of all invasive breast cancers, with pure mucinous carcinoma representing only around 2%. It is most commonly found in older patients, typically in the sixth to early eighth decade of life. We present the case of a 55-year-old female with a 15-year history of a painless, gradually enlarging palpable lump on her left breast. Upon examination, a 5 × 5 cm lump with well-defined margins and a hard consistency was found in the lower outer quadrant of the left breast. Histopathological examination confirmed a diagnosis of Mucinous Adenocarcinoma of the Left Breast. The patient underwent modified radical mastectomy and received adjuvant endocrine therapy with tamoxifen due to hormone receptor-positive status. Mucinous carcinoma of the breast is a unique entity with specific histological features including the presence of extracellular mucin pools. Immunohistochemical staining is crucial for determining hormone receptor status, which can guide treatment decisions. Although surgical intervention is the primary approach, the extent of surgery may vary, ranging from lumpectomy to mastectomy. Adjuvant therapies such as chemotherapy and radiotherapy may also be considered based on individual cases. This case underscores the importance of a multidisciplinary approach in managing rare subtypes of breast cancer, such as mucinous carcinoma. Accurate diagnosis, appropriate surgical intervention, adjuvant therapy, and long-term follow-up are critical components of treatment.
ABSTRACT
Introduction and importance: This case report presents an intriguing instance of a 35-year-old nonsmoker female who exhibited a convergence of acute necrotizing pneumonia (ANP) and squamous cell carcinoma (SCC), two distinct pulmonary conditions. ANP involves severe lung infection and tissue necrosis, while SCC is a non-small cell lung carcinoma originating from the bronchial epithelium. Such a unique combination in a nonsmoker female patient emphasizes the intricate interplay of diverse pulmonary pathologies and the importance of comprehensive diagnostic evaluation and effective patient management strategies. Case presentation: The patient's symptoms include fever, pain, cough, and sporadic hemoptysis. Initial imaging suggested ANP due to a multilobulated necrotic lung mass. Despite empirical antibiotic therapy, no improvement occurred, prompting further investigation. Positron emission tomography and computed tomography revealed intense fluorodeoxyglucose avidity in the lesion. A computer tomography-guided Tru-cut biopsy confirmed non-small cell carcinoma with squamous differentiation in the necrotic mass. Clinical discussion: ANP is a severe manifestation of pneumonia, predominantly affecting young, healthy individuals, while SCC, commonly linked to smoking, presents as non-small cell lung carcinoma. Overlapping symptoms and radiological findings complicate diagnosis. Early diagnosis and appropriate management are crucial for both conditions to prevent progression and complications. Conclusion: This case highlights the significance of precise diagnosis and adaptable treatment approaches. The coexistence of ANP and SCC in a nonsmoker female patient underscores the necessity of meticulous diagnostic evaluation and personalized treatment strategies. The scarcity of such presentations emphasizes the need for further research to comprehend the mechanisms underlying these occurrences.
ABSTRACT
Introduction: Mesothelioma is a rare and aggressive cancer that is primarily caused by asbestos exposure. However, cases of mesothelioma without asbestos exposure suggest the involvement of other risk factors. Sarcomatoid mesothelioma, which is characterized by spindle-shaped cells, is a particularly aggressive subtype with limited treatment options. Case presentation: The authors present a case of a 72-year-old man with no history of asbestos exposure who presented with abdominal pain, fatigue, and weight loss. Imaging revealed a large cystic mass in the liver. A Liver biopsy confirmed the diagnosis of sarcomatoid mesothelioma. Immunohistochemistry results further supported this diagnosis. Due to the advanced stage and tumor size, surgical resection was not feasible. Palliative chemotherapy was initiated, but the patient's condition deteriorated rapidly, leading to his demise. Conclusion: This case highlights the complexity of mesothelioma and the need for further research to identify the nonasbestos-related risk factors. Understanding alternative causative agents and mechanisms is crucial for the early detection, the development of targeted therapies, and improving patient outcomes. The presented case contributes to the existing literature and aligns with the Surgical CAse REport (SCARE) Criteria.
ABSTRACT
Key Clinical Message: Cortical venous thrombosis is a rare but severe complication of TBM that requires a high index of suspicion for early diagnosis. The treatment of CVT in TBM is based on anticoagulant therapy, which is known to improve the outcomes of the patients. Abstract: The case report describes an 18-year-old male in India with symptoms of tubercular meningitis complicated by cortical venous thrombosis. Tubercular meningitis is a rare but severe form of meningitis caused by tuberculosis bacteria and is a significant public health concern in India. The patient presented to the emergency department with a history of fever, headache, and vomiting for the past month, with a positive Mycobacterium tuberculosis test. The patient was started on standard antitubercular therapy and was diagnosed with cortical venous thrombosis via an MRI scan. Treatment included antitubercular therapy, anticoagulation therapy, dexamethasone, and antiemetic drugs. The patient's symptoms improved over 2 weeks of therapy. The case highlights the importance of early detection, treatment, and prevention strategies, such as the National Tuberculosis elimination program, in controlling the spread of tuberculosis in India. It also emphasizes the importance of close monitoring for complications in patients with tubercular meningitis, such as cortical venous thrombosis, which can be life-threatening.
