RESUMEN
Phototherapy is a recommended treatment regimen for different scleroderma spectrum disorders, but so far it has been included neither by European nor by worldwide experts committee in recommendations for the treatment of systemic sclerosis (SSc). The aim of the study was to revisit the utility of dermatological phototherapy in patients with SSc. PubMed using medical subject headings was searched to identify studies evaluating response to dermatological phototherapy in SSc patients. Both UVA1 (340-400 nm) and PUVA (psoralen plus UVA) treatments were found to reduce skin thickening and increase skin elasticity, therefore allowing for the improvement of joint tension mobility, especially in hands. At least several papers showed efficacy of phototherapy in patients who remained non-responsive to previous immunosuppressive therapies. The most probable mechanisms of action of phototherapy in SSc include inhibition of T-cells and prevention from dermal fibrosis. Although most data on the efficacy of phototherapy come from small experimental studies and case reports, phototherapy based on UVA of wavelength manifests relatively mild spectrum of side effects and this should be considered as a treatment option for SSc with dominant cutaneous involvement.

Introduction: Antazoline with propafenone may be an alternative to electrical cardioversion (ECV) in restoring sinus rhythm in patients with atrial fibrillation (AF), including during balloon cryoablation. Aim: To compare the efficacy of antazoline with propafenone and ECV in restoring and maintaining sinus rhythm at discharge in patients with AF during cryoablation with special regard to type of AF. Material and methods: The study retrospectively analyzed 196 patients who underwent elective cryoablation. Eighty-nine patients who developed AF in the perioperative period were selected as the study group (32 women and 57 men). The study group was divided into two groups - 46 (51.7%) patients were given pharmacological cardioversion with 70 mg of propafenone and 100 or 200 mg of antazoline, whereas the other 43 (48.3%) patients underwent ECV. Results: There were no statistically significant differences between the groups regarding: left atrial area, left atrium diameter, right atrial area and right atrium diameter. In the overall population, ECV was more effective than antazoline with propafenone therapy (31 [72.1%] vs. 20 [43.5%]; p = 0.01). A similar relationship was demonstrated in patients with persistent AF (13 [59.1%] vs. 3 [12.5%]; p = 0.002). There was no significant difference in the group of patients with paroxysmal AF (18 (85.6%) vs. 17 (77.3%); p = 0.7). Conclusions: In AF during the cryoablation procedure ECV appears to be more effective in restoring and maintaining sinus rhythm at discharge than antazoline with propafenone in the general AF patient population, especially in patients with persistent AF.
RESUMEN
INTRODUCTION: Atrial functional mitral regurgitation (afMR) is common in patients with atrial fibrillation (AF). The presence of functional tricuspid regurgitation (fTR), which arises as a secondary effect of afMR, has the potential to impact the effectiveness of procedures aimed at restoring normal heart rhythm. In this study, we sought to evaluate the efficacy of electrical cardioversion (CVE) in AF regarding the presence and degree of fTR in patients with afMR. MATERIAL AND METHODS: Retrospective analysis included 521 patients with persistent AF on optimal medical therapy undergoing CVE. 157 (30.1%) patients had afMR (characterized by left ventricle ejection fraction ≥ 50% and LA dilatation) and were divided into 2 groups: the group with fTR (107, 68.2%) and the group without fTR (50, 31.9%). RESULTS: Patients with afMR and fTR had a higher prevalence of metabolic syndrome (p = 0.02) and greater right atrial area (p < 0.01) compared to patients without fTR. The efficacy of CVE was lower in the group with fTR in comparison to patients with isolated afMR (82.2% vs. 94%; p = 0.048) and it was unrelated to the degree of fTR (p = 0.15) and RVSP (p = 0.56). The energy required for successful CVE was comparable regardless of the presence (p = 0.26) or severity of fTR (p = 0.94). CONCLUSIONS: The fTR frequently coexists with afMR and it significantly diminishes the effectiveness of CVE for treating AF. The degree of fTR does not appear to influence the efficacy of CVE.
RESUMEN
Background: Recent studies have changed the perception of rhythm control in the treatment of atrial fibrillation (AF). Functional mitral regurgitation (fMR) can be both a cause and a consequence of AF and may influence rhythm restoration procedures. Materials and methods: A retrospective analysis included 182 consecutive patients with AF on optimal medical therapy (OMT) undergoing electrical cardioversion (CVE). Based on transthoracic echocardiography, the study group was divided into 20 (11%) patients without mitral regurgitation (MR) and 132 (82%) with fMR 77 (58%) with atrial fMR (afMR; left ventricle ejection fraction (LVEF) ≥ 50%, left atrial (LA) dilatation) and 55 (42%) and with ventricular fMR (vfMR; LVEF < 50%). Patients with severe and organic MR were excluded from the study. Results: vfMR patients had a greater incidence of kidney failure (p = 0.01) and coronary heart disease (p = 0.02); more frequent use of diuretics during hospitalization (p < 0.01); greater LA diameter and area (p < 0.01; p < 0.01) than afMR patients. CVE efficiency was high in all four groups (84−95%). The presence and type of fMR did not affect the efficacy of CVE (p = 0.2; p = 0.9) and did not require the use of more energy (p = 0.4; p = 0.8). The independent predictor of successful CVE was the amount of white blood cells (OR 0.74, p < 0.05). Conclusions: Efficacy of CVE is high among AF patients on OMT regardless of the incidence and type of fMR. Subclinical inflammation should be excluded before elective CVE because it may decrease its efficacy.
RESUMEN
We sought to compare the safety and efficiency of Tiger-2 in the right radial and Judkins catheter in the left radial access. We retrospectively collected data of 487 patients, involving 172 patients after coronary angiography with Judkins on the left radial artery and 315 patients with Tiger-2 on the right radial artery access. There were no differences in baseline characteristics, except for hypertension ratio and mean age. There was a difference in pulse absence on the radial artery. The volume of contrast used was higher in the Judkins group. Both groups differed in the amount of drugs administered (NTG and heparin). Fluorescence times were comparable between groups. Radiation dosage and AK was significantly greater in the Tiger-2 group. The Tiger-2 catheters were significantly more often changed to another type of catheter (100 changes) than the Judkins (12 changes). However, there was no statistical difference in access site change. Judkins with left radial access seems to be a safer option because of the lower radiation exposure and less incidence of complications than Tiger-2 with right radial access, however, it requires a higher volume of contrast.
