[The six dimensions of positive health valued by different stakeholders within mental health care]. / De waardering van de zes dimensies van positieve gezondheid in de ggz.

BACKGROUND: In recent years a new concept of health, 'positive health', has been developed, which focusses on a person's resilience instead of merely the absence of disease. A previous survey among a variety of stakeholders in general health care showed that there are differences in how dimensions of positive health are valued. Patients valued the spiritual and societal participation dimension higher than physicians and policymakers. AIM: To investigate how the six dimensions of positive health are valued by patients, health care professionals and policymakers in mental health care in the Netherlands, and to test whether these values differ from such stakeholders in general healthcare. METHOD: In a cross-sectional survey patients (N= 458), healthcare professionals (N=250) and policy makers (N=47) of two mental health care institutions in the Netherlands filled in an online survey. The results were compared to the results of the study by Huber e.a. (2016) by ANCOVA, paired T-tests and cohens' d. RESULTS: Respondents valued all dimensions equally high. No significant differences between groups were found, except for a significant difference on daily functioning. Patients rated this dimension significantly higher than other stakeholders. The equal significance of the six dimensions is in contrast with the findings of a previous survey among stakeholders in general health care. CONCLUSION: In contrast to stakeholders in general health care, those in mental health care valued all dimensions of health of equal and high importance. Only daily functioning was rated lower by professionals and policymakers than by patients.

Clinical outcome of ablation for long-standing persistent atrial fibrillation with or without defragmentation.

OBJECTIVE: To assess the outcome and associated risks of atrial defragmentation for the treatment of long-standing persistent atrial fibrillation (LSP-AF). METHODS: Thirty-seven consecutive patients (60.4 ± 7.3 years; 28 male) suffering from LSP-AF who underwent pulmonary vein isolation (PVI) and linear ablation were compared. All patients were treated with the Stereotaxis magnetic navigation system (MNS). Two groups were distinguished: patients with (n = 20) and without (n = 17) defragmentation. The primary endpoint of the study was freedom of AF after 12 months. Secondary endpoints were AF termination, procedure time, fluoroscopy time and procedural complications. Complications were divided into two groups: major (infarction, stroke, major bleeding and tamponade) and minor (fever, pericarditis and inguinal haematoma). RESULTS: No difference was seen in freedom of AF between the defragmentation and the non-defragmentation group (56.2 % vs. 40.0 %, P = 0.344). Procedure times in the defragmentation group were longer; no differences in fluoroscopy times were observed. No major complications occurred. A higher number of minor complications occurred in the defragmentation group (45.0 % vs. 5.9 %, P = 0.009). Mean hospital stay was comparable (4.7 ± 2.2 vs. 3.4 ± 0.8 days, P = 0.06). CONCLUSION: Our study suggests that complete defragmentation using MNS is associated with a higher number of minor complications and longer procedure times and thus compromises efficiency without improving efficacy.

Adenosine testing after cryoballoon pulmonary vein isolation improves long-term clinical outcome.

BACKGROUND: Adenosine infusion after pulmonary vein isolation (PVI) with radiofrequency energy reveals dormant muscular sleeves and predicts atrial fibrillation (AF) recurrence. The aim of our study was to determine whether adenosine could reveal dormant PV sleeves after cryoballoon isolation and study its effect on long-term recurrence of AF. METHODS: Patients with paroxysmal AF underwent cryoballoon PVI. After PVI, adenosine 25 mg was infused to test for dormant muscular sleeves in each vein. If reconnection under adenosine was shown, further cryoballoon ablation was performed until no more reconnection occurred. Follow-up was performed with ECG, 24-h Holter recording, and a symptom questionnaire at three monthly intervals. Transtelephonic Holter monitoring was performed for 1 month before and 3 months after PVI. Patients who underwent cryoballoon PVI without adenosine administration were used as controls for comparison. RESULTS: In the study group (n = 34, 24 males), adenosine revealed dormant sleeves in 9/132 (8 %) veins, and 7/34 (21 %) patients. All but one vein was further treated until the dormant sleeves were isolated. During a mean follow-up of 520 ± 147 days, 23/34 (68 %) patients were free of AF without antiarrhythmic drugs (AADs). In the control group (n = 65, 46 males), 29/65 (46 %) were free of AF without AADs. There were significantly less AF recurrences in the study group (p = 0.04). CONCLUSIONS: Adenosine administration after cryoballoon PVI reveals dormant muscular sleeves in 21 % of patients. Clinical follow-up shows that adenosine testing is effective in reducing AF recurrence after cryoballoon ablation.

Migraine accompagnée after transseptal puncture.

Migraine has never been reported as a complication of transseptal puncture for ablation of atrial fibrillation. We studied its incidence before and after such procedures after observing some striking new migraine in several patients. A total of 8% of procedures for pulmonary vein isolation with a 15 Fr sheath used for transseptal puncture were associated with new headache with ocular symptoms or migraine within three months. Exacerbation of pre-existing migraine was reported in another 7% of procedures. More complaints were seen in redo procedures. The questionnaires were performed at three months after the intervention and there was no more evidence of persisting flow over the atrial septum at that time, when most complaints had already disappeared. This has important implications for follow-up after ablation for atrial fibrillation. (Neth Heart J 2010;18:374-5.).

Acute success and short-term follow-up of catheter ablation of isthmus-dependent atrial flutter; a comparison of 8 mm tip radiofrequency and cryothermy catheters.

OBJECTIVES: To compare the acute success and short-term follow-up of ablation of atrial flutter using 8 mm tip radiofrequency (RF) and cryocatheters. METHODS: Sixty-two patients with atrial flutter were randomized to RF or cryocatheter (cryo) ablation. Right atrial angiography was performed to assess the isthmus. End point was bidirectional isthmus block on multiple criteria. A pain score was used and the analgesics were recorded. Patients were followed for at least 3 months. RESULTS: The acute success rate for RF was 83% vs 69% for cryo (NS). Procedure times were similar (mean 144+/-48 min for RF, vs 158+/-49 min for cryo). More applications were given with RF than with cryo (26+/-17 vs. 18+/-10, p<0.05). Fluoroscopy time was longer with RF (29+/-15 vs. 19+/-12 min, p<0.02). Peak CK, CK-MB and CK-MB mass were higher, also after 24 h in the cryo group. Troponin T did not differ. Repeated transient block during application (usually with cryoablation) seemed to predict failure. Cryothermy required significantly less analgesia (p<0.01), and no use of long sheaths (p<0.005). The isthmus tended to be longer in the failed procedures (p=0.117). This was similar for both groups, as was the distribution of anatomic variations. Recurrences and complaints in the successful patients were similar for both groups, with a very low recurrence of atrial flutter after initial success. CONCLUSIONS: In this randomized study there was no statistical difference but a trend to less favorable outcome with 8 mm tip cryocatheters compared to RF catheters for atrial flutter ablation. Cryoablation was associated with less discomfort, fewer applications, shorter fluoroscopy times and similar procedure times. The recurrence rate was very low. Cryotherapy can be considered for atrial flutter ablation under certain circumstances especially when it has been used previously in the same patient, such as in an AF ablation.

Magnetic navigation in AV nodal re-entrant tachycardia study: early results of ablation with one- and three-magnet catheters.

AIMS: Steering soft, flexible catheters using an external magnetic field could have advantages for heart catheterization, especially for therapy of tachyarrhythmias. Our aims were to assess the feasibility of magnetic navigation to Koch's triangle and reliable ablation of atrioventricular nodal re-entry tachycardia (AVNRT) with a magnetic catheter. METHODS AND RESULTS: Consecutive patients with AVNRT were mapped and ablated with a magnetically enabled catheter (Helios I or II), with, respectively, one and three magnets at the tip. The catheter was remotely advanced with the Cardiodrive system and orientated with the Navigant control system. After initial positioning with the external magnets, adjustment was made in 5 degrees steps. Success rates, procedure, and fluoroscopy times were analysed, and compared with a local contemporary series of conventional AVNRT ablations. Magnetic navigation was feasible in all 20 patients. Targets were easily reached. Catheters remained stable in position during accelerated junctional rhythms. Ablation was successful in 18/20 procedures (90%). No significant complications occurred. Median patient fluoroscopy time was 12 min, median physician fluoroscopy time was 4 min. Fluoroscopy times tended to be shorter than that in the conventionally treated group. Procedure duration decreased significantly over time, median procedure time was similar to that in the conventional group. CONCLUSION: AVNRT can be successfully mapped and ablated using magnetic navigation. A learning curve was evident, unrelated to catheter type, but to increasing operator experience. Physician radiation times were one-third of patient times. No complications occurred. Procedure time is comparable with that of conventional ablation.

Electrical isolation of pulmonary veins using cryothermal energy: study design and initial results.

In the September 2003 issue of the Netherlands Heart Journal, the wrong figures where inserted in this article. The article is reprinted here with the correct figures. BACKGROUND: Atrial fibrillation (AF) is the most frequently encountered arrhythmia. Radiofrequency pulmonary vein (PV) ablation is promising for symptomatic paroxysmal AF, but is associated with a significant risk of PV stenosis. OBJECTIVES: To assess the efficacy of cryothermal PV ablation and the incidence of PV stenosis. METHODS: Highly symptomatic patients with paroxysmal or persistent AF were eligible for cryothermal ablation. Multislice spiral CT scans were performed before, and three months after ablation. AF burden was assessed using transtelephonic ECG recording and by telephone enquiry. RESULTS: An attempt was made to isolate 27 PVs in 15 patients. In total, 20 PVs could be isolated (74% acute success). No significant difference in PV diameter was seen before and after ablation. Five out of 12 patients with paroxysmal AF were completely without AF after one ablation procedure. An additional two patients reported a significant reduction in symptoms. In the three patients with persistent AF no improvement was reported. CONCLUSION: Cryothermal PV ablation was effective in isolation of the targeted PVs. It appears to be safe, as no PV stenosis was seen in this study three months after the ablation. Taking into account a learning curve, we consider the clinical results to be very promising.
