Pulmonary hypertention

The hepatopulmonary syndrome is defined as the triad of liver disease, pulmonary gas exchange abnormalities leading to arterial deoxygenation and widespread pulmonary vascular dilatation. It is one of the not infrequently cases of dyspnea within patients with liver disease. We report the case of a 32-year-old woman with cirrohsis and portal hypertention who presented with dyspnea worsning progressively. The blood gas revealed a deep hypoxemia with a PaO2 rate 42mmHg but clinically well tolerated. Pulmonary embolism and pneumonia were rapidly excluded by a CT pulmonary angiography...

BACKGROUND: Noncompaction of ventricular myocardium(NVM) is a rare kind of cardiomyopathy associated with genetic mutations and nongenetic factors, among which the isolated right ventricular noncompaction (iRVNC) is the most rare type. ACVRL1 is the pathogenic gene of type 2 hereditary hemorrhagic telangiectasia (HHT2), and there's no NVM reported to be associated with ACVRL1 mutation. CASE PRESENTATION: This is a rare case diagnosed as iRVNC and pulmonary hypertention with ACVRL1 mutation detected...

PURPOSE: Pulmonary endarterectomy (PEA) is a curative surgical option for patients with chronic thromboembolic pulmonary hypertension (CTEPH), a disease resulting from chronic pulmonary thromboembolism. The role of sarcopenia (i.e. low skeletal muscle mass) has been shown to be associated with adverse outcomes in surgical populations, but its significance with PEA remains unknown. We sought to evaluate the association of sarcopenia with measures of CTEPH severity and post-operative hospital outcomes...

We report a case of a 60-year-old man with postoperative congestive heart failure( CHF) successfully treated with tolvaptan. The patient was diagnosed with pulmonary hypertension due to mitral stenosis and regurgitation combined with tricuspid regurgitation. He underwent mitral and tricuspid valvuloplasty. His postoperative course was uneventful until CHF symptoms secondary to volume overload appeared on the 4th day. Congestion with pulmonary hypertension was treated with 0.042 μg/kg/min of intravenous human atrial natriuretic peptide (hANP)...

Firefighting is extremely strenuous and physically demanding work and involves ability to cope with emergency life-or-death situations. Because of the high physical demands of firefighting, successful job performance and minimizing of morbidity and mortality depends on fitness for duty. The firefighting department of Tehran does not perform periodic medical assessment for firefighters. The aim of this study was to evaluate medical fitness among firefighters in Tehran. In this cross sectional study we examined 147 firefighters...

OBJECTIVE: Necrotizing enterocolitis (NEC) is a common and devastating gastrointestinal condition of neonatal infants. The pathophysiology of NEC remains poorly understood. We tried to evaluate the effectiveness of inhaled NO compared to L-arginine usage in necrotizing enterocolitis model in rats. MATERIAL-METHODS: 46 newborn pups from 4 time-mated Sprague-Dawley pregnant rats were divided equally into 4 groups as follows: NEC (subjected to NEC), NEC + L-arginine, NEC + inhaled NO and control...

BACKGROUND: Pregnant women with heart disease are at high risk. Studies of risk factors of these patients are of great significance to improve maternal and fetal outcomes. In this paper, we try to discuss the main risk factors of cardiac events in pregnant women with heart disease and to establish a risk assessment system. METHODS: A retrospective analysis was carried out for pregnancies in 1741 women with heart disease who delivered in Shanghai Obstetrical Cardiology Intensive Care Center between January 1993 and September 2010...

Cardiac tumors are rare, and 3-quarters of these tumors are benign and nearly half of the benign tumors are myxomas. Metastases to the heart are more common than primary cardiac tumors. Cardiac tumors present obstructive, constitutional and embolic signs and symptoms. Echocardiograms, chest computed tomography (CT) and magnetic resonance imaging (MRI) scan are very useful for diagnosis. Surgery is indicated in patients with benign tumor, and chemo/radio-therapy in patients with malignant tumors. Prognosis after surgery is good, instead poor prognosis for patients with malignancy...

BACKGROUND: Hemodynamic evaluation is crucial for the management of patients with pulmonary hypertention. Clinicians often prefer a rapid and non-invasive method. This study aimed to examine the feasibility of transthoracic echocardiography for the measurements of hemodynamic parameters in patients with pulmonary hypertension. METHODS: A prospective single-center study was conducted among 42 patients with pulmonary hypertension caused by different diseases. Transthoracic echocardiography and right-heart catheterization were performed within 24 hours...

We report a 43-year-old female who developed pulmonary arterial hypertension (PAH) during intensive immunosuppressive therapy for systematic lupus erythematosus (SLE). She was diagnosed as SLE at the age of 32 years based on serological and hematological abnormalities, oral ulcers, and facial erythema. She experienced frequent flare-ups of disseminated discoid lupus between the ages of 33 and 36 years and developed immune thrombocytopenia at the age of 39 years. In 2007 when she was 43 years old, she developed lupus nephritis (LN) with elevated serum anti-double stranded DNA antibodies and urine protein of less than 1 g/day...

Diagnosis and treatment of sleep related breathing disorders have become an essential challenge of internal medicine. They are highly important clinically because of the impairment of daytime performance, attention and concentration with elevated risk of accidents in workplace and traffic and because of their consequences on cardiovascular and metabolic disorders. The obstructive sleep apnoea syndrome (OSAS) has proven to be one of the most important risk factors for arteriosclerosis, especially in the cerebral vessels...

AIM: To study the effect of chimonin on chronic hypoxia and hypercapnic pulmonary hypertension and to explore its mechanism. METHODS: SD rats were randomly divided into normal control group (A), hypoxic hypercapnic group(B), hypoxic hypercapnia + chimonin group (C). HO-1 and HO-1 mRNA was observed in pulmonary arterioles of rats by the technique of immunohistochemistry and in situ hybridization. RESULTS: (1) mPAP was significantly higher in rats of B group than that of A and C group...

Pulmonary trunk aneurysm is generally associated with congenital cardiac defects, pulmonary hypertension, or infection. Idiopathic pulmonary trunk aneurysm without any associated diseases is a rare lesion and has seldom been reported. Here, we report a case of a 68-year-old woman with idiopathic pulmonary trunk aneurysm. The maximum diameter of the aneurysm was 53 mm while she was 142 cm in height. We successfully performed aneurysmorrhaphy and her postoperative course was uneventful. Aneurysmorrhaphy was an effective technique for idiopathic pulmonary trunk aneurysm without pulmonary hypertention...

INTRODUCTION: Tracheotomy is one of the most oldest operations in surgery. Percutaneous dilational tracheotomy has become increasingly popular as an alternative to standard tracheotomy over the last 30 years. It is particularly useful in patients who require prolonged mechanical ventilation, in the intensive care units. Percutaneous tracheotomy is a technique that can be performed at the bedside. It is cost effective, minimally invasive and can be done rapidly. CASE REPORT: We report a case of subglottic stenosis after percutaneous tracheotomy...

OBJECTIVE: It has been shown that triptolide can attenuate pulmonary arterial hypertension in rats. This study was designed to investigate the therapeutic effect of triptolide on pulmonary hypertension in rats and possible mechanisms. METHODS: Sixty Sprague-Dawley (SD) rats were randomly divided into 6 groups: normal control, model, continuous triptolide-treated, delayed triptolide-treated and two placebo groups for continuous and delayed fashions (n=10 each). The rats from the last 5 groups were injected with monocrotaline (MCT, 60 mg/kg) on day 7 after left pneumonectomy...

It is not uncommon that valve disease is complicated with Kawasaki disease (KD). However, it is rare to show normal coronary arteries simultaneously. We experienced a case of valvuloplasty towards the mitral regurgitation (MR) followed immediately after KD showing normal coronary arteries. A 3 year-old-female, with a diagnosis of KD at 4 months after birth, was referred to our hospital 5 months after birth. The echocardiography detected a moderate MR. The preoperative catheterization at 2.5 years old showed grade III MR, enlargement of left atrium and left ventricle, pulmonary capillary wedge pressure (PCWP) = 12 mmHg, left ventricular ejection fraction (LVEF) = 675, and normal coronary arteries...

A 57-year-old woman suffering from pleural and pericardial effusion, pulmonary hypertention, lymphadenopathy, hepatosplenomegaly, edema, hypertrichosis, small hemangioma and polyneuropathy was diagnosed as Crow-Fukase syndrome. Osteoctomy of the left second rib and irradiation of this rib and the left iliac bone were performed. Serum vascular endothelial growth factor (VEGF) level decreased to less than one-half the level before the operation (from 5,180 to 2,150 pg/ml). Immediately after the operation, pleural and pericardial effusions due to hyperpenetration improved, and polyneuropathy and hypertrichosis due to hypervasularity also gradually improved...
