Diagnosis, Genetics, and Management of 24 Patients With Cardiac Paragangliomas: Experience From a Single Center.

Context: Paragangliomas located within the pericardium represent a rare yet challenging clinical situation.

Objective: The current analysis aimed to describe the clinical characteristics of cardiac paragangliomas, with emphasis on the diagnostic approach, genetic background, and multidisciplinary management.

Methods: Twenty-four patients diagnosed with cardiac paraganglioma (PGL) in Peking Union Medical College Hospital, Beijing, China, between 2003 and 2021 were identified.

Surgery for angiosarcoma and other cardiac sarcomas: A single-institution experience.

Background: Cardiac sarcomas are rare malignancies with a poor prognosis. Although angiosarcoma is the most common histological subtype, its features are poorly characterized. This study aimed to compare the clinical characteristics of the various cardiac sarcomas and the surgical techniques used and to identify factors influencing the prognosis.

Repair versus replacement for active endocarditis of the mitral valve: 9 years of experience.

Background And Aim: To determine the factors contributing to successful mitral valve repair (MVP) and to discuss the effect of complex techniques on the durability of MVP for active infective endocarditis (IE) affecting the mitral valve.

Methods: One hundred and eighty-seven patients were enrolled; 39.6% underwent mitral valve replacement (MVR) and 60.

Outcomes of surgical treatment for active infective endocarditis under COVID-19 pandemic.

Background: The coronavirus disease 2019 (COVID-19) pandemic has been and will continue to be a challenge to the healthcare system worldwide. In this context, we aimed to discuss the impact of the COVID-19 pandemic on the diagnosis, timing, and prognosis of surgical treatment for active infective endocarditis (IE) during the pandemic and share our coping strategy.

Methods: A total of 39 patients were admitted for active IE in the year 2020.

Outcomes of surgery for functional cardiac paragangliomas: A single-center experience of 17 patients.

Objective: Cardiac paragangliomas are rare neuroendocrine tumors. Early surgical treatment improves clinical symptoms and prolongs survival. We review our experience in 17 patients who underwent surgical resection for functional cardiac paraganglioma.

Surgical Treatment Strategies of Intravenous Leiomyomatosis withRight Cardiac Cavities Extension.

Objective To investigate the diagnosis and surgical treatment strategies of intravenous leiomyomatosis(IVL)extending through inferior vena cava into the right cardiac cavities. Methods Thirty patients of IVL extending through inferior vena cava into the right cardiac cavities were treated in Peking Union Medical College Hospital from November 2002 to January 2015.The following variables were studied: age,cardiopulmonary bypass time,deep hypothermic circulatory arrest time,origins of IVL,blood loss,duration of post-operative hospital stay,hospitalization expenses,edema of lower extremity,blood transfusion,postoperative complication,residual IVL,and re-grow or recurrence.

Surgical treatment of pulmonary artery aneurysm: an institutional experience and literature review.

Objectives: The occurrence of pulmonary artery aneurysm (PAA) is extremely rare in the clinical setting. Careful treatment should be considered because of the possibility of fatal complications including rupture, dissection, pulmonary embolism and heart failure. Our goal is to contribute a better understanding of this disease and its treatment.

Angiosarcoma of the pericardium: a case report.

Background: Primary malignant tumors of the pericardium are rare, and most primary malignant pericardium tumors are mesotheliomas. Primary pericardial angiosarcoma is extremely rare, and it is associated with a poor prognosis.

Case Presentation: We report of a 47-year-old woman who complained of activity-related chest tightness and shortness of breath.

[Endoscopic Saphenous Vein Harvesting versus Open Vein Harvesting Techniques].

Objective: To investigate whether endoscopic saphenous vein harvesting (EVH )reduces leg wound morbidity and improves rehabilitation of lower extremity as compared to open vein harvesting (OVH) in patients with coronary artery disease.

Methods: The clinical data of 333 patients who underwent isolated coronary artery bypass graft surgery (CABG) between January 2007 and December 2011 were retrospectively analyzed.These patients were divided into EVH group (n=210) and OVH group (n=123).

[Cannulated screw fixation through posteromedial approach screw for the treatment of tibial avulsion fracture of the tibial attachment of the posterior cruciate ligament].

Objective: To explore therapeutic effects of cannulated screw fixation through posteromedial approach for the treatment of tibial avulsion fracture of the tibial attachment of the posterior cruciate ligament.

Methods: From February 2007 to March 2012, 36 patients with tibial avulsion fracture of the tibial attachment of the posterior cruciate ligament were reviewed. Among the patients, 28 patients were male and 8 patients were female, ranging in age from 16 to 57 years old,averaged 35 years old.

In vivo and in vitro imaging tracing of dual-labeled bone mesenchymal stem cells transplanted into myocardium of F344 rats.

Objective: To investigate the feasibility of in vitro and in vivo magnetic resonance imaging (MRI) and fluorescence imaging tracking of transplanted bone mesenchymal stem cells (BMSCs) dual-labeled with ultrasmall superparamagnetic iron oxide (USPIO) and red fluorescence protein (RFP).

Methods: BMSCs were incubated with culture medium containing USPIO for 24 hours. The Prussian-blue staining, transmission electron microscopy and trypan-blue staining were used to study the efficacy and safety of labeling.

Surgical removal of a giant vegetation on permanent endocavitary pacemaker wire and lead.

Pacemaker lead infections are rare. There are only about 0.4%-1.

[Surgical treatment of chronic pulmonary thromboembolism].

Objective: To evaluate the perioperative management and safety of pulmonary thromboendarterectomy for chronic pulmonary thromboembolism.

Methods: From March 1999 to March 2004, 12 patients with chronic pulmonary thromboembolism received thromboendarterectomy. The operation was performed under cardio-pulmonary bypass with low flow or circulative arrest and deep hypothermia.
