[62-year old male patient with position-depending dyspnoe after hemipneumectomia]. / 62-jähriger Patient mit lageabhängiger Dyspnoe nach einseitiger Pneumektomie.

BACKGROUND: Dyspnoe is a symptom with a huge differential diagnostic spectrum. According to patients hemodynamic, acute forms can be caused by myocardial infarction, pulmonary embolism, pulmonary edema and heart rhythm disturbances while chronic forms can be caused by restrictive myocardial and pericardial diseases, hematooncological diseases, orthopedic deformations and chronic pulmonary diseases. The platypnea-orthodeoxia syndrome with underlying interatrial connection is a rare cause and need a special diagnostic work-up. CASE REPORT: A 62-year old male patient with previously known pneumectomy on right side due to underlying cancer presented with a 6-months history of increasing dyspnoe (NYHA III) on exertion and upright position. The physical examination just revealed a lack of ventilation on right side. The saturation drops from 97% in supine position to 68% in upright position. Transesophageal echocardiography revealed a compressed right atrium with a persisted foramen ovale (PFO) and atrial septal aneurysm resulting in a right-left shunt. After completing diagnostic work-up and excluding other possible causes for dyspnoe an interventional closure of interatrial connection was performed. Subsequently the symptoms of the patients resolved (NYHA I). CONCLUSION: The Platypnea-Orthodeoxia-Syndrome isa rare cause of dyspoe. The diagnosis can be made by echocardiography. Medical treatment of such disease is of less success, thus a closure of interatrial connection is recommended.

Transcatheter Mitral Valve Repair via MitraClip in Patients Aged <65 Years: Multicentre 2-year Outcomes.

Background: Transcatheter mitral valve repair (TMVR) using the MitraClip has become a well-established interventional therapy and is usually performed in elderly patients. The objective of this study was to assess 2-year clinical outcomes of TMVR in patients aged <65 years at three heart centres with severe mitral regurgitation (MR) and no surgical options. Methods: A retrospective study analysed data of 36 patients aged <65 years treated with TMVR . All patients were refused surgery by Heart Team decision. Baseline MR was assessed by biplane vena contracta width in two perpendicular views (mean 8.35 ± 1.87 mm). Degenerative MR was detected in 11 patients (30.6%); functional MR was detected in 25 patients (69.4%). Results: Acute procedural success was accomplished in 88.9% of patients. No procedure-related mortality during the first 30 days was detected. Over an average of 2 years of follow-up, all-cause mortality was 19.4% and cardiovascular death was 11.1% owing to advanced heart failure. The average follow-up period was 25.8 months (median was 20 months). Statistically significant difference (p-value <0.01) was detected for N-terminal prohormone of brain natriuretic peptide (pg/ml) at baseline (mean 9,870 ± 10,819; median 7,748) compared to follow-up visits (mean 7,645 ± 11,292; median 3,263). New York Heart Association functional class improvement was achieved in 69% of patients. A second intervention (reclipping) was required in two patients to correct recurrent significant MR. Conclusion: TMVR in patients aged <65 years refused surgical repair provides satisfactory clinical outcomes at 2 years. Future studies should evaluate the outcomes of MitraClip in this population in a larger cohort.

Carotid artery stenting: do procedural complications relate to the side intervened upon?: results from the Carotid Artery Stent (CAS)-Registry of the Arbeitsgemeinschaft Leitende Kardiologische Krankenhausärzte (ALKK).

OBJECTIVES: To determine the influence of the side intervened upon on outcomes during carotid artery stenting (CAS). BACKGROUND: Anatomic and technical aspects may influence the results of CAS. The value of the side intervened upon has not been analyzed yet. METHODS: We analyzed data from the Carotid Artery Stent (CAS)-Registry. RESULTS: A total of 3,165 CAS procedures, 1,613 (51%) at the left and 1,552 (49%) at the right carotid artery were included. There was a higher proportion of patients treated for symptomatic stenoses when CAS was performed at the left carotid artery (50.1% versus 45.8%, P = 0.016) and more patients already had prior carotid endarterectomy (8.5% versus 5.8%, P = 0.003). Interventions at the left side took 3 min longer than interventions at the right side (46.6 +/- 24.3 versus 43.8 +/- 23.6, P = 0.003). In patients treated at the left carotid artery amaurosis fugax (0.7% versus 0.1%, P = 0.005), ipsilateral stroke (3.1% versus 1.8%, P = 0.017), and the primary endpoint of in-hospital death or stroke (4.1% versus 2.3%, P = 0.005) occurred significantly more often. Even after adjusting for confounding parameters, CAS procedures performed at the left carotid arteries remained an independent predictor of death or stroke (OR = 1.77, 95% CI: 1.15-2.72, P = 0.009). CONCLUSIONS: In current clinical practice, CAS is performed frequently at the right carotid artery as at the left carotid artery. CAS interventions have a higher in-hospital complication rate if performed at the left carotid artery. Technical improvements might help to overcome this situation.

In-flight cardiac arrest and in-flight cardiopulmonary resuscitation during commercial air travel: consensus statement and supplementary treatment guideline from the German Society of Aerospace Medicine (DGLRM).

By the end of the year 2016, approximately 3 billion people worldwide travelled by commercial air transport. Between 1 out of 14,000 and 1 out of 50,000 passengers will experience acute medical problems/emergencies during a flight (i.e., in-flight medical emergency). Cardiac arrest accounts for 0.3% of all in-flight medical emergencies. So far, no specific guideline exists for the management and treatment of in-flight cardiac arrest (IFCA). A task force with clinical and investigational expertise in aviation, aviation medicine, and emergency medicine was created to develop a consensus based on scientific evidence and compiled a guideline for the management and treatment of in-flight cardiac arrests. Using the GRADE, RAND, and DELPHI methods, a systematic literature search was performed in PubMed. Specific recommendations have been developed for the treatment of IFCA. A total of 29 specific recommendations for the treatment and management of in-flight cardiac arrests were generated. The main recommendations included emergency equipments as well as communication of the emergency. Training of the crew is of utmost importance, and should ideally have a focus on CPR in aircraft. The decision for a diversion should be considered very carefully.

Fifteen-year experience with carotid artery stenting (from the carotid artery stenting-registry of the Arbeitsgemeinschaft Leitende Kardiologische Krankenhausärzte).

To date only sparse data are available on trends and changes in indications, patient's characteristics, and clinical outcome of patients undergoing carotid artery stenting (CAS) in clinical practice. From February 1996 to December 2010, 6,116 CAS procedures were performed in 5,976 patients at 36 hospitals within the prospective, multicenter CAS registry of the Arbeitsgemeinschaft Leitende Kardiologische Krankenhausärzte. Median age of patients was 71 years, 71.6% were men; a symptomatic stenosis was treated in 50.3% and an embolic protection device (EPD) was used in 82.5% of the patients. The overall hospital mortality or stroke rate was 3.1%. Stroke or in-hospital death occurred in 4.0% in symptomatic patients and in 2.2% in asymptomatic patients. In a logistic regression model, independent predictors of in-hospital death or stroke were heart failure (odds ratio [OR] 2.03, 95% confidence interval [CI] 1.22 to 3.36, p = 0.006), symptomatic stenosis (OR 1.52, 95% CI 1.05 to 2.18, p = 0.03), and age (OR per 10 years 1.46, 95% CI 1.17 to 1.81, p <0.001). The use of an EPD was significantly associated with a lower rate of death or stroke in the registry (OR 0.45, 95% CI 0.26 to 0.78, p = 0.004). From 1996 to 2010, mean age of patients increased by 4.1 years (p <0.001), the proportion of male patients decreased from 82.4% to 70.2% (p = 0.07), the proportion of symptomatic stenoses decreased (84.6% to 24.7%, p <0.001), and the use of EPDs increased from 1.4% to 97.2% (p <0.001). Comparing 2 periods from 1996 to 2003 and 2004 to 2010, a numeric decrease in the in-hospital stroke or death rate was seen in symptomatic (4.7% vs 3.5%, p = 0.11), and in asymptomatic patients (2.9% vs 2.1%, p = 0.27) undergoing CAS, which did not reach statistical significance. In conclusion, the proportion of symptomatic carotid artery stenoses decreased significantly; EPDs established as a standard tool and a numeric decrease of in-hospital stroke or death was seen in asymptomatic and symptomatic patients undergoing CAS in clinical practice over the last 15 years.

Carotid artery interventions for restenosis after prior stenting: is it different from interventions of de novo lesions? Results from the carotid artery stent (CAS)--registry of the Arbeitsgemeinschaft Leitende Kardiologische Krankenhausärzte (ALKK).

OBJECTIVE: To compare characteristics and outcome of patients with re-stenoses after prior carotid artery stenting (CAS) treated with repeat carotid interventions (Re-CI) with CAS for de novo lesions. BACKGROUND: The treatment of re-stenosis is a major problem in vascular interventions. Patients with re-stenoses after prior CAS treated with Re-CI are not well defined. METHODS: We analyzed data from the prospective ALKK CAS Registry. RESULTS: Out of 3,817 CAS procedures 95 were intended in 93 patients (2.5%) for a restenosis after prior CAS and 3,722 CAS in 3,655 patients (97.5%) for a de novo stenosis. There was no difference in age (p = 0.302) or distribution of gender (p = 0.545) between the two groups. Patients treated for a restenosis after CAS were less likely to be treated for a symptomatic lesion (22.7 vs. 40.1%, p = 0.001). Coronary heart disease (p = 0.017), peripheral arterial disease (p < 0.001) as well as diabetes mellitus (p = 0.004) were more prevalent in the restenosis group. Lesions were less complicated in restenosis patients, with less ulcers (7.4 vs. 19.9%, p = 0.003) and less severe calcifications (7.4 vs. 23.6%, p < 0.001). The intended interventions were more often not performed in the Re-CI group (9.5 vs. 3.3%; p = 0.001). In-hospital, the stroke or death rate was 0% in the Re-CI group as compared to 3.1% in the de novo group (p = 0.115). CONCLUSIONS: Patients treated with Re-CI for repeat stenoses after prior CAS represent 2.5% of current CAS patients. Although representing a subgroup with more concomitant diseases, Re-CI seems to be associated with lower event rates as compared to CAS for de novo lesions.

Carotid artery stenting in octogenarians: results from the ALKK Carotid Artery Stent (CAS) Registry.

AIMS: We tried to determine the influence of age on complication rates of carotid artery stenting (CAS). METHODS AND RESULTS: Two thousand seven hundred eighty CAS procedures were included in the registry. Median age of the patients was 70.8 years, with a proportion of octogenarians of 11.2% and a significant increase between 1996 (5.9%) and 2005 (13.7%; P for trend = 0.002). In octogenarians, a symptomatic stenosis was a more frequent indication for CAS (60.7% vs. 48%, P < 0.001), the CAS procedure was aborted more frequently (6.9% vs. 2.2%; P < 0.001) and the duration of intervention was longer (Median 45 vs. 40 min; P = 0.008). Increasing age was associated with a significant increase in the in-hospital death or stroke rate (P for trend: 0.001). In-hospital death or stroke rate was also higher in octogenarians compared with younger patients (5.5 vs. 3.2%; P = 0.032, OR = 1.79; 95%CI: 1.04-3.06). Logistic regression analysis showed that age analysed as a continuous variable was a strong predictor of in-hospital death or stroke (P < 0.001), whereas octogenarians had only a trend towards a higher event rate (P = 0.062). CONCLUSION: CAS in octogenarians is performed in an increasing proportion of patients. In-hospital stroke or death rates increase significantly with older age; however, there was no excess complication rate in octogenarians.

Positron emission tomography/computed tomography improves diagnostics of inflammatory arteritis.

Based on the unique property of fluorine-18 fluorodeoxyglucose, localization and follow-up of hypermetabolic processes is possible with positron emission tomography (PET). The dual-modality PET/computed tomography (CT) systems provide intrinsically fused morphologic and functional data in a single examination. We report on two patients with inflammatory aortitis and positive PET/CT findings. A 57-year-old woman with an inflammatory process involving the thoracolumbal aorta with an aneurysm and a 48-year-old woman with an aneurysm of the thoracic aorta and pronounced fluorodeoxyglucose-uptake. The advantages in differentiation of vessel wall structures compared with PET or CT alone are pointed out.
