Pulmonary Hypertension and Thromboembolic Disease

2008

Pulmonary hypertension (PH) is a disease group that includes a wide variety of entities leading to an increased pulmonary arterial pressure. This chapter describes the basic mechanisms that lead to PH and the possibilities of MRI in diagnosing different aspects. A MR imaging protocol is provided making MRI a comprehensive modality for the classification of the underlying disease and assessment of hemodynamics.

P2772The rule-out criteria for chronic thromboembolic pulmonary hypertension can identify patients without haemodynamic abnormalities and functional …

2019

Abstract Background Up to one-third of patients report persisting hemodynamic abnormalities and functional limitation over long-term follow-up after acute pulmonary embolism (PE). Purpose We tested whether a validated algorithm designed to rule-out chronic thromboembolic pulmonary hypertension (CTEPH) after acute PE can be used for identifying patients at lower risk of presenting with persisting symptoms and echocardiographic abnormalities. Methods The multicentre Follow-up of Acute Pulmonary Embolism (FOCUS) cohort study prospectively enrolled 1,100 consecutive patients diagnosed with acute symptomatic PE; two-year follow-up is ongoing. We focused on the scheduled visits for 3- and 12-mont…

Pulmonale Thrombendarteriektomie bei thromboembolischer pulmonaler Hypertonie: Indikationen und Frühergebnisse

2008

Pulmonary thrombendarterectomy was performed in 32 patients (14 men and 18 women; mean age 38 +/- 15 years) with thromboembolic pulmonary hypertension (New York Heart Association stage III: n = 22; stage IV: n = 10). The preoperative arterial pO2 averaged 59 +/- 11 mm Hg; pulmonary vascular resistance (PVR) and mean pressure (MPAP) were increased to 1,045 +/- 430 dyn.s.cm-5 and 53 +/- 12 mm Hg, respectively. The perioperative death rate was 22% (7 of 32). In the 25 survivors the pulmonary hypertension was reduced to a PVR of 194 +/- 75 dys.s.cm-5, MPAP of 28 +/- 6 mm Hg. Subsequent re-examination in 15 patients (NYHA stage I: n = 14, stage II: n = 1) after a mean of 17 +/- 5 months demonstr…

P2540Sex-specific differences in the clinical presentation, surgical complications, and course of chronic thromboembolic pulmonary hypertension

2019

Abstract Background Women are more susceptible to develop several forms of pulmonary hypertension, but they may have better survival rates than men. Sparse data are available concerning sex-specific differences in chronic thromboembolic pulmonary hypertension (CTEPH). Purpose and methods We investigated sex-specific differences in the clinical presentation of CTEPH, functional parameters, exposure to pulmonary endarterectomy (PEA), and survival. Results Women constituted half of the study population (N=679 treatment-naïve patients from the European CTEPH registry) and were characterized by a lower prevalence of some cardiovascular risk factors (e.g. prior acute coronary syndrome, smoking ha…

Duplexsonographie abdomineller Gefäße

1987

Duplex sonography is a non-invasive procedure which permits the determination of flow velocity and direction in visceral vessels. Results in 50 normals have shown that small arteries can be evaluated in about 50% of cases. The portal venous system can be demonstrated in all cases; average flow velocity and volume is 15.2 +/- 2.8 cm/s and 694 +/- 230 ml/min, corresponding with the values obtained by invasive methods. Clinical application for duplex examinations can be found in portal hypertension, varices, thromboses, aneurysms and transplant kidneys.

Effects of Antihypertensive Treatment on Peripheral Flow of the Lower Limbs

The clinical pattern determined in subjects that undergo a high and prolonged pressure regime is defined as “hypertensive disease”.
