Etiological diagnosis and frequency of pericardial involvement in malignant diseases. Prognostic relevance of pericar-dial effusion in patients with malignant diseases TO THE EDITOR: Malignancy is a common cause of peri-cardial effusion, and malignant pericardial effusion is a serious manifestation in advanced malignancies [1]. Malignancy-related pericardial effusion is associated with significantly decreased patient survival [1]. Slight malignant pericardial effusions are frequently asymptomatic; however, symptomatic patients often present with cardiac tamponade, which can rapidly lead to cardiovascular collapse or death [2]. Therefore, early diagnosis and timely treatment may decrease a patient's short-term risk of death. We evaluated both the etiology and prognosis of pericardial involvement in several malignancies. We retrospectively reviewed the records of 215 patients (126 males and 89 females) with pericardial effusion and malignant diseases, including solid tumors and hemato-logical malignancies, from January 1991 to December 2010. In all cases, the clinical diagnosis was confirmed by pathological examination of the primary tumor site. All patients underwent pericardiocentesis, and pericardial fluid analyses were performed for cytology. We analyzed the incidence of the etiology of malignancies and overall survival according to the results of the pericardial fluid analysis. Overall survival was calculated from the day of initial diagnosis to the date of patient's death from any other cause or to the latest follow-up date. Among 215 patients, 113 (52.6%) showed pericardial involvement in their malignant diseases. The etiological diagnosis and pericardial fluid analysis results are summarized in Table 1. Pericardial involvement of malignancy was most frequent in breast carcinoma (85.0%), followed by lung adenocarcinoma (61.9%), gastric adenocarcinoma (58.8%), thymic carcinoma (33.3%), and esophageal squamous cell

Prognostic value of right ventricular myocardial performance index in patients undergoing coronary artery bypass surgery
Abstract Background: Right ventricular myocardial performance index (RVMPI) is a Doppler–derived parameter of non-geometrical ventricular function that measures both systolic and diastolic functions of the right ventricle. The aim of this study is to compare prognostic value of RVMPI with global RV function in patients undergoing Coronary Artery Bypass Graft (CABG). Methods: In a longitudinal ...

Objective: Cardiac tamponade is a life-threatening clinical entity that requires an emergency treatment. Cardiac tamponade can be caused both by benign and malignant diseases. A variety of methods have been described for the treatment of these cases from needle-guided pericardiocentesis, balloon-based techniques to surgical pericardiotomy. The Authors report their experience in...
متن کاملComparison of the prevalence of pericardial effusion and cardiac tamponade after cardiac surgery with and without chest tube suction in patients referred to Chamran hospital, Isfahan
Background: Pericardial effusion is one of the most important complications of cardiac surgeries. Administration of a low-power suction to the mediastinal or pleural chest tube of patients helps better and constant drainage of pericardial or pleural secretions after surgeries. This technique might change the secretion and discharges of patients and might change the outcomes of surgeries. Metho...
متن کاملPrognostic factors affecting survival of patients with cancer-related pericardial effusion managed by surgery
BACKGROUND Although pericardial effusion (PE) is not uncommon in patients with cancer, it may lead to cardiac tamponade, a life-threatening condition. Prompt life-saving treatment is essential, and also allows the continuation of the cancer treatment. The aim of this study was to determine the prognostic factors for survival in patients with cancer who were treated surgically for PE. METHODS ...
