Disturbed right ventricular ejection pattern as a new Doppler echocardiographic sign of acute pulmonary embolism.

Transthoracic echocardiography (TTE) is frequently performed in patients with suspected acute pulmonary embolism (APE) to search for right ventricular (RV) pressure overload. We prospectively assessed the diagnostic value of a new Doppler echocardiographic sign of APE based on the disturbed RV ejection pattern ("60/60 sign") and compared its diagnostic performances with that of the presence of RV pressure overload, as well as with "McConnell sign" based on RV regional wall motion abnormalities. We assessed 100 consecutive patients with clinical suspicion of APE, including those with previous cardiorespiratory diseases.

Effects of beraprost sodium, an oral prostacyclin analogue, in patients with pulmonary arterial hypertension: a randomized, double-blind, placebo-controlled trial.

Objectives: The purpose of this study was to assess the efficacy and safety of beraprost sodium, an orally active prostacyclin analogue, in New York Heart Association (NYHA) functional class II and III patients with pulmonary arterial hypertension (PAH).

Background: Pulmonary arterial hypertension is a life-threatening disease for which continuous intravenous infusion of prostacyclin has been proven effective. However, this treatment is associated with serious complications arising from the complex delivery system.

Outcome after cardiopulmonary resuscitation in patients with pulmonary arterial hypertension.

Patients with pulmonary arterial hypertension (PAH) often die from right heart failure or sudden cardiac death. Cardiopulmonary resuscitation (CPR) may be instituted in these patients but there are no data in the medical literature about the outcome of CPR in this group of patients. We conducted a retrospective multicenter international study on the frequency and results of CPR in patients with PAH.

[Pulmonary embolism: the past and . . . the future].

The history of pulmonary embolism cannot be reconstructed reliably beyond the last two centuries, starting with the Napoleon's times by the works of Laennec. We owe the first pathological and clinical descriptions to European scientists, especially French, German and Italian. Interestingly, some ideas regarding pathophysiology and even hemodynamics can be found in papers published as early as the end of the 19th century.

[Use of temporal vena cava filter in a patient with a high risk of perioperative pulmonary embolism].

Intraluminal caval filter placement can be applied in order to prevent pulmonary embolism. When surgery has to be performed in the patient with proximal deep venous thrombosis anticoagulant therapy should be reduced and filter placement is indicated. Temporary filter appears an interesting option, as it can be removed shortly after surgical intervention, when contraindications to anticoagulation no longer exist.

[Recombinant hirudine in suspected heparin induced thrombocytopenia--case report of pulmonary embolism].

A case of 68 years old women suffering from chronic anemia, myelodysplastic syndrome and treated with progestogen due to endometrial hypertrophy is presented. Initially she was admitted to a regional hospital because of progressive weakness and exertional dyspnea. Three months earlier she reported an episode of acute dyspnea and chest pain.

[Thrombectomy in a patient with a mobile clot in the inferior vena cava--case report].

Switching from heparin to acenocoumarol was complicated by severe retroperitoneal bleeding in a 50-years old patient with massive pulmonary embolism and deep venous thrombosis. The haematomas were evacuated by surgical procedure. Planned insertion of a vena cava filter was abandoned because of a mobile clot in inferior vena cava (IVC) reaching above renal veins as evidenced by spiral computed tomography (SCT).

[Secondary anticoagulant prophylaxis with low molecular heparins or oral anticoagulants and bone mineral density].

A broad spectrum of indications for low molecular weight heparin (LMWH) requires an assessment of side effects especially during prolonged administration. There are common risk factors for venous thromboembolism (VTE) and osteoporosis; heparin is "the drug of choice" for VTE treatment. The aim of our study was to assess the effect of treatment and prophylaxis with LMWH (enoxaparine sodium) and oral anticoagulant (acenocoumarol) for bone structure.

[Transesophageal echocardiography--a method for prompt diagnosis of acute hemodynamically significant pulmonary embolism].

Unlabelled: Patients with acute pulmonary embolism (PE) may require prompt confirmation of PE before aggressive therapy such as embolectomy or thrombolysis. However, emergency availability of routine diagnostic tests often remains a problem. Therefore, we assessed prospectively the diagnostic value of transesophageal echocardiography (TEE), recently reported to be useful in the diagnosis of PE.

[LGM inferior vena cava filters--observation of 79 patients].

The aim of the study was to assess effectiveness and safety of the LGM inferior vena cava (IVC) filters in patients with venous thromboembolic disease. In the Department of Internal Medicine of Institute of Tuberculosis and Lung Diseases in Warsaw 79 LGM IVC filters have been inserted since 1993. Indications for filters placement were as follows: recurrent pulmonary embolism (pe) despite anticoagulation--17 patients (pts), severe bleeding complications of thrombolytic or anticoagulant therapy--11 pts, contraindications for thrombolytic and/or anticoagulant treatment--5 pts, massive pe--14 pts, chronic thromboembolic-major vessel pulmonary hypertension (CTEPH)--30 pts, extensive deep vein thrombosis of lower limbs or vena cava inferior in patients with urgent indications for surgery--24 pts.

[Pulmonary thrombendarterectomy in treatment of patients with chronic thromboembolic pulmonary hypertension].

20 consecutive patients with thromboembolic pulmonary hypertension underwent pulmonary thromboendarterectomy. Mean pulmonary artery pressure decreased from mean 49.9 +/- 9.

[Differences in hemodynamics of thromboembolic and primary pulmonary hypertension].

It is not clear whether right ventricle to pulmonary artery coupling is modified by the site of vascular obstruction in patients with chronic severe pulmonary hypertension. We compared invasively (Swan Ganz) and non-invasively (echo/ /Doppler) assessed hemodynamics between two groups of patients with severe chronic thromboembolic pulmonary hypertension (CTEPH)--(n = 6; 52 +/- 24 yrs) and pulmonary arterial hypertension (PAH) (n = 5; 42 +/- 9 yrs) who had similar invasively measured right ventricular systolic pressure (CTEPH: 78 +/- 14 mm Hg; PAH: 83 +/- 17 mm Hg; p = NS), mean pulmonary arterial pressure (CTEPH: 51 +/- 10; PAH 56 +/- 11 mm Hg, p = NS) and pulmonary vascular resistance (CTEPH: 15.6 +/- 4.

[Usefulness of measuring levels of d-dimer for diagnosis of hospital venous thromboembolism].

D-dimer measurement with highly sensitive tests seems useful to rule out pulmonary embolism (PE) and deep vein thrombosis (DVT). However, nonspecific increase in d-dimer is common among inpatients. The aim of our study was to check: 1) whether the frequency of normal DD level in inpatients justifies its assessment as a part of diagnostic strategy for VTE, 2) whether tests that we are using are sensitive enough to exclude PE and DVT.

[Echocardiography improves the chance of conclusive results in spiral computed tomography of suspected pulmonary embolism].

While highly specific for detecting thromboembolism in proximal pulmonary arteries, spiral computed tomography (spiral CT) cannot reliably exclude pulmonary embolism. Therefore "negative" spiral CT in patients with high clinical probability of acute pulmonary embolism should be considered as non-conclusive. The goal of our study was to check whether echo/Doppler could stratify patients with suspected pulmonary embolism according to the chance of obtaining a conclusive spiral CT result.

Diagnostic value of transoesophageal echocardiography in suspected haemodynamically significant pulmonary embolism.

Objective: To assess the value of transoesophageal echocardiography (TOE) for diagnosing suspected haemodynamically significant pulmonary embolism and signs of right ventricular overload at standard echocardiography.

Methods: 113 consecutive patients (58 male; 55 female), mean (SD) age 53.6 (13.

Efficacy of sequential antiarrhythmic treatment in sinus rhythm maintenance after successful electrocardioversion in patients with chronic non-valvular atrial fibrillation.

Background: Sequential use of antiarrhythmic drugs may improve prognosis in chronic atrial fibrillation (AF). We conducted a prospective study of the efficacy of sequential antiarrhythmic drug therapy in sinus rhythm (SR) maintenance after a successful electrocardioversion (CV) in pts with chronic AF.

Material And Methods: 58 pts (64.

Visualization of the central pulmonary arteries by biplane transesophageal echocardiography.

It is suggested that transesophageal echocardiography (TEE), by detecting thromboemboli in the proximal parts of the pulmonary arteries, is useful in the diagnosis of pulmonary embolism. However, the data on visualization of the pulmonary arteries are limited. The extent of the pulmonary arteries that can be precisely visualized during biplane TEE was assessed in 51 consecutive patients (23 female, 28 male, aged 56.

Factors related to the early and late success of direct current cardioversion of chronic nonrheumatic atrial fibrillation: An echocardiographic study.

Objectives: To assess factors related to the success of restoration and one-year maintenance of sinus rhythm in chronic (more than 48 h) nonrheumatic atrial fibrillation (AF).

Methods And Results: One hundred and fifty consecutive patients aged 62+/-9 years with AF lasting 123+/-254 days were evaluated clinically with transthoracic and transesophageal echocardiography before elective direct current cardioversion. Heart chamber dimensions and left ventricular ejection fraction were measured.

[Should sinus rhythm be restored in patients with chronic atrial fibrillation? Preliminary results from the Polish "Hot Cafe" study].

Atrial fibrillation (AF) is the most common arrhythmia occurring in clinical practice. It is the most frequent cause of hospitalization in cardiac rhythm disturbance. Despite comprehensive progress in the research into electrophysiological mechanisms leading to this loss of normal rhythm and new procedures dealing with it, the main problem being the conversion to and maintaining the normal sinus rhythm (SR) has not been solved.
