Abstract
Background & Objectives: Thrombosis with high mortality is a serious complication of prosthetic heart valves and requires treatment, which includes reoperation or using filbrinolytic medications. Regarding the importance of the issue and high mortality rate in reoparation, the present study was performed to determine the efficacy and pragnosis of fibrinolytic therapy on mechanical prosthetic valve. Methods: This prospective study was preformed on seventeen patients with PVT who had undergone treatment with streptokinase (SK). After the primary diagnosis, the response to treatment was echocardiography and TEE. Patients with large clots or equal to 1cm clots, pregnant women and patients who had been operated in a month prior to the study were excluded. Results: Of the 17 patients (9 female and 8 male, mean age= 43.8 ± 11) 14 had mechanical double-let prostheses (8 mitral & 6 aortic) and 3 patients had single-let prostheses (1 aortic and 2 mitral). 71.3% of the patients with a double-let prosthesis responded completely to the treatment with SK. In none of the patients with a single-let prosthesis the treatment was successful. Also treatment of acute thrombosis was more effective in aortic position (71.4%) than in mitral– valve (50%) (p=0.02). Mortality rate due to cerebral bleeding was 5.8%. Two systemic embolic events (11.8%) occurred (1 cerebral and 1 renal) with transient signs. Conclusion: The use of fibrinolytic agents was effective, relatively safe and available especially in patients with less than two weeks’ presentation, small clot and NYHA class I and II and in aortic-position thrombosis.

Abstract
Background & Objectives: Mitral valve prolapse (MVP) syndrome is one of the most prevalent abnormalities of mitral valve that arises from pathologic changes of the various parts of mitral valve. MVP may lead to ECG changes, like T wave inversion in inferior leads and atrial and ventricular arrhythmias, in some people that may be misdiagnosed as myocardial ischemia. Methods: This was an analytical (case-control) study in 50 cases with MVP with age below 30 years who had referred to the Ardabil Bouali Hospital and some private cardiology clinics. The diagnosis of MVP was based on clinical and echocardiographic findings, and after taking history and physical examination, an ECG and an echocardiogram were taken from each person in case and control groups and the acquired information was analyzed via statistical methods of SPSS software. Results: From 50 studied cases with MVP, 60% (30 cases) were female and 40% (20 cases) were male, and the most common age range was 21 – 25 years. From these cases, 68% (34 persons) had changes in their ECGs while %32 (16 subjects) did not. In control group, from 50 persons, 44% (22 persons) had ECG changes and 56% (28 persons) did not. Conclusion: In general this study showed that increase in ECG changes in MVP group in comparison with control group (p=0.01). In cases with MVP, there was not significant relationship between gender and ECG changes. In comparing case and control groups, there was not significant difference in ECG changes in females, while there was a significant difference in males (14 of 20 versus 6 of 20) w ith considering that ECG changes in persons with MVP may be misdiagnosed as ischemic heart disease,it is recommended that cases (especially men) with MVP always keep a record of their ECGs.

Abstract
Background & Objectives: Heart failure (HF) is a pathophysiologic state in which cardiac dysfunction leads to insufficient pumpage of blood for metabolic needs of body. One of the important problems in primary approach to patients with HF, is estimation of HF severity. The present research is an attempt to investigate the accuracy of CXR in diagnosis of HF severity especially in emergency wards. Methods: This sensitivity analysis study was conducted on 59 patients admitted to emergency ward of Buali Hospital during March–September 2003, with primary diagnosis of HF. One randiologist used to observe and report radiologic findings without knowing the results of each cardiography.Then cardiologists used to check on the reports and selected patients whose EF was under 50% and eventually sensitivity and specificity of radiologic findings in diagnosing severity of HF (EF ≤ 35%) were calculated. Results: 59 patients (53% female and the rest male) were investigated whose age mean was 65.6±10.9 EF mean was 33.4±9.09. In the diagnosis of pulmonary arterial hypertension, CXR had 72% sensivity and 18% specifity, considering the reliance on the CXR in diagnosis of severe HF (EF ≤ 35%) findings were: cardiomeglay (94%), pulmonary artery congestion (75%), interstitial edema (78%) and alveolar edema (76%) with high specifity the reliance on the combination of pulmonary cephalization, interstitial edema and pleural effusion was to have 92% sensivity and 10% specifity. Conclusion: According to high sensitivity of cardiomegaly, pulmonary arterial congestion, interstitial edema and pleural effusion, lack of there findings in CXR reduce probability of severe HF. Alveolar edema because of its high specificity increases probability of severe HF. CXR also has high sensivity in diagnosis and R/O of PAH.
