Introduction: It is currently debated whether cardiac resynchronization therapy (CRT) has an effect on the burden of ventricular arrhythmias (VA). We investigated whether the reverse remodeling after CRT may reduce the occurrence of VA. Methods : The study included 398 patients enrolled in the InSync ICD Italian Registry, treated with CRT-D and with a follow-up of at least 12 months. Spontaneous VA detected by the device were reviewed and validated. Results: After 6 months of follow-up no VA episodes occurred in 319 patients (group 1), while VA episodes persisted in the remaining 79 (group 2). At baseline, clinical and echocardiographic characteristics of the two groups were comparable: NYHA class (2.9±0.6 vs. 3.0±0.7), QRS width (166±31ms vs. 163±34ms), ejection fraction (26±7% vs. 26±6%), LVEDV (251±98ml vs. 226±45ml), LVESV (182±84ml vs. 158±38ml) (All p=NS). At 6 month visit, ventricular remodeling was apparent only in group 2 pts: LVEDV (200±83ml, p=0.042 vs. Baseline), LVESV (133±65ml, p=0.002 vs. Baseline). No changes were evident in group 2 pts: LVEDV (216±69ml, p=0.769 vs. Baseline), LVESV (160±59ml, p=0.521 vs. Baseline). The long-term survival from all-cause death resulted higher in group 1 pts (Log-rank test: p=0.032). (Figure ) Conclusions: In patients treated with CRT, a reduction of ventricular arrhythmic events occurs during the initial 12 months following implant and is correlated with the degree of ventricular remodeling induced by the therapy. Patients demonstrating the remission of arrhythmic episodes will have better survival and more pronounced long term improvements.

Abstract Background Superresponders to cardiac resynchronization therapy (CRT) demonstrate significant reverse remodeling, improvement in cardiac function, decrease in inflammatory mediators and markers of cardiac fibrosis. It is not clear if superresponse (SR) can be early or late and if the time of SR to CRT is associated with different degree of biochemical improvement. Aim To assess structural and functional heart parameters, sympathetic activity, levels of biomarkers of myocardial fibrosis, inflammatory and neurohormonal mediators in patients with various time of SR to CRT. Methods The study enrolled 82 superresponders to CRT (decrease in left ventricular end-systolic volume (LVESV) >30%) (mean age 60.4±9.3 years; 80.5% men, 19.5% women; 54.9% with ischemic etiology of heart failure). Patients were divided into two groups: group 1 (n=19) – SR was achieved within 24 months (14.0 [8.0; 21.0] months); group 2 (n=63) - SR was achieved after 24 months (59 [43.0; 84.0] months). Echocardiographic parameters, plasma levels of epinephrine, norepinephrine, NT-proBNP, interleukin (IL) 1β, IL-6, IL-10, tumor necrosis factor alpha (TNF-α), metalloproteinase (MMP) 9, tissue inhibitors of metalloproteinase (TIMP) 1 and 4 were evaluated. Results At baseline there were no differences in demographic, clinical and echocardiographic characteristics between the groups. Levels of epinephrine (1.1 [0.1; 2.2] ng/ml vs 2.1 [0.7; 3.4] ng/ml; p=0.049) and IL-10 (1.8 [1.5; 3.5] pg/ml vs 3.9 [2.7; 5.1] pg/ml; p=0.019) were significantly higher in group 2. Both groups demonstrated significant improvement in echocardiographic parameters. On follow-up left ventricular (LV) end-systolic dimension (p=0.041), LV end-diastolic dimension (p=0.049), LVESV (p=0.014), LV end-diastolic volume (p=0.045) were lower in group 2. In group 1 IL-6 (p=0.047), TNF-α (p=0.047) decreased significantly and there was a tendency for IL-1β (p=0.064) and norepinephrine (p=0.069) levels to increase. In group 2 levels of IL-1β (p<0.001), IL-6 (p=0.030), IL-10 (p=0.003), TNF-α (p<0.001), TIMP-1 (p=0.010) and epinephrine (p=0.024) decreased significantly while MMP-9/TIMP-1 (p=0.023) increased as compared to baseline levels. Additionally there was a tendency for NT-proBNP level to decrease in group 2 (p=0.069). Follow-up level of norepinephrine (7.8 [2.9; 17.2] ng/ml vs 1.1 [0.2; 8.7] ng/ml; p=0.011 was lower and MMP-9/TIMP-4 level was higher (0.058 [0.044; 0.091] vs 0.092 [0.064; 0.111]; p=0.013) in group 2. Diverse trends were observed in IL-10 (0.4 [−0.6; 1.2] pg/ml in group 1 vs −2.3 [−3.4; −0.5] pg/ml in group 2; p=0.007) and norepinephrine (4.0 [−5.2; 14.3] ng/ml in the group 1 vs −1.2 [−11.6; 4.0] ng/ml in the group 2; p=0.015) between the groups. Conclusion CRT modulates sympathetic, neurohumoral, immune and fibrotic activity. Late SR to CRT is associated with decrease of sympathetic and inflammatory activity and more pronounced LV reverse remodeling.

Background Successful anatomic repair of congenitally corrected transposition of the great arteries achieves excellent outcomes. Several centers report excellent long-term survival with the Fontan pathway as well. We have selectively applied both approaches depending on individual patient morphology, with anatomic repair preferred but utilizing the Fontan pathway when high technical complexity or operative risk is anticipated. Methods Hospital records over an 18-year period (1998–2016) were reviewed to identify patients with congenitally corrected transposition of the great arteries who underwent surgical management. Physiological repairs and hypoplastic ventricles were excluded. Patient- and procedure-related variables were reviewed. Results We identified 19 patients. Group 1 consisted of 12 anatomic repairs, of which 10 (83.3%) required prior interim staging procedures. Mean age at anatomic repair was 2.6 ± 1.3 years, mean follow-up was 8.7 ± 5.3 years. Nine (75%) patients experienced important complications and 4 (33.3%) required reintervention during follow-up. There were no deaths; one patient required heart transplantation. Group 2 (7 patients) underwent Fontan palliation. Mean age at Fontan completion was 7.2 ± 3.8 years, mean follow-up was 6.3 ± 4 years. There was no reintervention, death, or transplant. Conclusion Patients with congenitally corrected transposition of the great arteries and two adequate-sized ventricles do well with both anatomic repair and the Fontan pathway in the medium term. Excellent outcomes with reduced early complication and reintervention rates can be achieved for this cohort of patients when a strategy of avoiding complex anatomic repair in favor of the Fontan pathway is used.

<b><i>Background and Purpose:</i></b> Hemodynamic evaluation of moyamoya patients is crucial to decide the treatment strategy. Recently, CO<sub>2</sub>-triggered BOLD MRI has been shown to be a promising tool for the hemodynamic evaluation of moyamoya patients. However, the longitudinal reliability of this technique in follow-up examinations is unknown. This study aims to analyze longitudinal follow-up data of CO<sub>2</sub>-triggered BOLD MRI to prove the reliability of this technique for long-term control examinations in moyamoya patients. <b><i>Methods:</i></b> Longitudinal CO<sub>2</sub> BOLD MRI follow-up examinations of moyamoya patients with and without surgical revascularization have been analyzed for all 6 vascular territories retrospectively. If revascularization was performed, any directly (by the disease or the bypass) or indirectly (due to change of collateral flow after revascularization) affected territory was excluded based on angiography findings (group 1). In patients without surgical revascularization between the MRI examinations, all territories were analyzed (group 2). <b><i>Results:</i></b> Eighteen moyamoya patients with 39 CO<sub>2</sub> BOLD MRI examinations fulfilled the inclusion criteria. The median follow-up between the 2 examinations was 12 months (range 4–29 months). For 106 vascular territories analyzed in group 1, the intraclass correlation coefficient was 0.784, <i>p</i> &#x3c; 0.001, and for group 2 (84 territories), it was 0.899, <i>p</i> &#x3c; 0.001. Within the total follow-up duration of 140 patient months, none of the patients experienced a new stroke. <b><i>Conclusions:</i></b> CO<sub>2</sub> BOLD MRI is a promising tool for mid- and long-term follow-up examinations of cerebral hemodynamics in moyamoya patients. Systematic prospective evaluation is required prior to making it a routine examination.

Proximal tibiofibular dislocation in closing-wedge high tibial osteotomy increases the risk of medium and long-term total knee replacement. Background: High tibial osteotomy is an effective treatment for medial osteoarthritis in young patients with varus knee. The lateral closing-wedge high tibial osteotomy (CWHTO) may be managed with tibiofibular dislocation (TFJD) or a fibular head osteotomy (FHO). TFJD may lead to lateral knee instability and thereby affect mid- and long-term outcomes. It also brings the osteotomy survival rate down. Objective: To compare the CWHTO survival rate in function of tibiofibular joint management with TFJD or FHO, and to determine whether medium and long-term clinical outcomes are different between the two procedures. Material & Methods: A retrospective cohort study was carried out that included CWHTO performed between January 2005 to December 2018. Those patients were placed in either group 1 (FHO) or Group 2 (TFJD). Full-leg weight-bearing radiographs were studied preoperatively, one year after surgery and at final follow-up to assess the femorotibial angle (FTA). The Rosenberg view was used to assess the Ahlbäck grade. The Knee Society Score (KSS) was used to assess clinical outcomes and a Likert scale for patient satisfaction. The total knee replacement (TKR) was considered the end of the follow-up and the point was to analyze the CWHTO survival rate. A sub-analysis of both cohorts was performed in patients who had not been FTA overcorrected after surgery (postoperative FTA ≤ 180°, continuous loading in varus). Results: A total of 230 knees were analyzed. The follow-up period ranged from 24–180 months. Group 1 (FHO) consisted of 105 knees and group 2 (TFJD) had 125. No preoperative differences were observed in terms of age, gender, the KSS, FTA or the Ahlbäck scale; neither were there any differences relative to postop complications. The final follow-up FTA was 178.7° (SD 4.9) in group 1 and 179.5° (SD 4.2) in group 2 (p = 0.11). The Ahlbäck was 2.21 (SD 0.5) in group 1 and 2.55 (SD 0.5) in group 2 (p = 0.02) at the final follow-up. The final KSS knee values were similar for group 1 (86.5 ± 15.9) and group 2 (84.3 ± 15.8). Although a non-significant trend of decreased HTO survival in the TFJD group was found (p = 0.06) in the sub-analysis of non-overcorrected knees, which consisted of 52 patients from group 1 (FHO) and 58 from group 2 (TFJD), 12.8% of the patients required TKR with a mean of 88.8 months in group 1 compared to 26.8% with a mean of 54.9 months in the case of group 2 (p = 0.005). However, there were no differences in clinical and radiological outcomes. Conclusion: TFJD associated with CWHTO shows an increase in the conversion to TKR at medium and long-term follow-up with lower osteotomy survival than the CWHTO associated with FHO, especially in patients with a postoperative FTA ≤ 180° (non-overcorrected). There were no differences in clinical, radiological or satisfaction results in patients who did not require TKR. Level of evidence III. Retrospective cohort study.

The immediate and long-term outcomes, complications, recurrences and the need for retreatment were analyzed in a series of 280 consecutive patients with anterior communicating artery aneurysms treated with the endovascular technique. From October 1992 to October 2001 280 patients with 282 anterior communicating artery aneurysms were addressed to our center. For the analysis, the population was divided into two major groups: group 1, comprising 239 (85%) patients with ruptured aneurysms and group 2 comprising of 42 (15%) patients with unruptured aneurysms. In group 1, 185 (77.4%) patients had a good initial pre-treatment Hunt and Hess grade of I-III. Aneurysm size was divided into three categories according to the larger diameter: less than 4 mm, between 4 and 10 mm and larger than 10 mm. The sizes of aneurysms in groups 1 and 2 were identical but a less favorable neck to depth ratio of 0.5 was more frequent in group 2. Endovascular treatment was finally performed in 234 patients in group 1 and 34 patients in group 2. Complete obliteration was more frequently obtained in group 2 unlike a residual neck or opacification of the sac that were more frequently seen in group 1. No peri-treatment complications were recorded in group 2. In group 1 the peri-treatment mortality and overall peri-treatment morbidity were 5.1% and 8.1% respectively. Eight patients (3.4%) in group 1 presented early post treatment rebleeding with a mortality of 88%. The mean time to follow-up was 3.09 years. In group 1, 51 (21.7%) recurrences occurred of which 14 were minor and 37 major. In group 2, eight (23.5%) recurrences occurred, five minor and three major. Two patients (0.8%) presented late rebleeding in group 1. Twenty-seven second endovascular retreatments were performed, 24 (10.2%) in group 1 and three (8.8%) in group 2, seven third endovascular retreatments and two surgical clippings in group 1 only. There was no additional morbidity related to retreatments. Endovascular treatment is an effective method for the treatment of anterior communicating artery aneurysms allowing late rebleeding prevention. Peri-treatment rebleeding warrants caution in anticoagulation management. This is a single center experience and the follow-up period is limited. Patients should be followed-up in the long-term as recurrences may occur and warrant additional treatment.

Purpose. To evaluate the efficacy and safety of femtolaser-assisted phacoemulsification in glaucomatous eyes in the long-term follow-up. Materials and methods. A retrospective analysis of the results of the surgical treatment of patients with combined cataract and glaucoma pathology was analyzed. The patients were divided into groups depending on the method of surgical intervention: 1) phacoemulsification with femtolaser support (26 eyes, 23 patients); 2) phacoemulsification (36 eyes, 30 patients); Results. Before surgery, there were no statistically significant differences in IOP and corneal hysteresis (СН) between groups 1 and 2. The mean values of IOP cc, IOP g and СН of group 1 before surgery were 22.7±6.1 mm Hg, 20.9±6.9 mm Hg, 8.5±1.6 mm Hg; 2 group – 22.9±8.7 mm Hg, 21.6±8.9 mm Hg, 8.9±1.6 mm Hg respectively. Average values of IOP cc, IOP g and CН 5 years after the surgical treatment in group 1 were 15.3±1.2 mm Hg, 14.4±3.4 mm Hg, 9.6±4.2 mm Hg; in group 2 – 18.0±4.2 mm Hg, 16.1±4.2 mm Hg, 8.8±2.2 mm Hg respectively. In both groups, stabilization of IOP and CH indices was noted, which remained throughout the entire observation period, which shows the normalization of the biomechanical properties of the corneoscleral membrane of the eye in the long-term postoperative period. Conclusion. Femtolaser accompaniment of phacoemulsification is an effective and safe method of cataract surgery for combined pathology. Key words: femtolaser, cataract, glaucoma, phacoemulsification.

Background: Many studies have demonstrated that deferral of percutaneous coronary intervention (PCI) on the basis of a myocardial fractional flow reserve (FFR) ≥0.75 is associated with a very low coronary event rate. However, some groups have empirically chosen the cut-off value of 0.80 rather than 0.75 for decision to defer PCI and the FFR measurement between 0.75 and 0.80 has been established as a grey zone. The aim of this study was to evaluate the long-term clinical outcomes of patients with moderate coronary lesions and FFR measurements between 0.75 and 0.80. Methods: The study included 125 anigiographically moderate coronary lesions (>50% diameter stenosis by visual assessment) in 125 patients but in whom the PCI was deferred on the basis of an FFR ≥ 0.75. The FFR was calculated as the ratio of mean distal pressure divided by the proximal pressure during hyperemia. Patients were divided into two groups according to the result of FFR: ≥ 0.80 (n=99, group 1) and between 0.75 and 0.79 (n=26, group 2). We evaluated the long-term major adverse cardiovascular events (MACE) related and unrelated to the FFR-evaluated lesion. Results: During a follow-up period of 82 ± 29 months (mean ± SD), The Kaplan-Meier event-free survival curves showed that group 2 was poorer than group 1 in prognosis (p=0.0148). The incidence of MACE unrelated FFR-evaluated lesion in group 1 was equivalent to that in group 2 (p=0.96). Conclusions: In patients with moderate coronary lesions and borderline FFR measurements, deferral of PCI was associated with a higher rate of MACE related to the FFR-evaluated lesion. FFR cut-off point of 0.80 instead of 0.75 may be more appropriate for deferring PCI.

Abstract Background Truncating genetic variants in titin (TTNtv) are identified in 15–25% of patients with primary dilated cardiomyopathy (DCM). Previous genotype/phenotype studies have reported conflicting results regarding disease severity and pathologic features associated with TTNtv. Purpose To investigate the natural history, reversibility and burden of arrhythmias associated with TTNtv in a Danish cohort with long-term follow-up. Methods Patients with DCM, recruited from two Danish tertiary centers, were included based on the presence of a TTNtv in a cardiac expressed titin exon. Data on patients' medical history including symptoms, demography, family history, comorbidities, treatment, ECG features, and echocardiograms were registered. Outcome data including all-cause mortality, need of heart transplantation (HTX) or left ventricular assist device (LVAD), and presence of ventricular and supraventricular arrhythmias were registered. Left ventricular reverse remodeling (LVRR) was defined as an absolute increase in left ventricular ejection fraction (LVEF) ≥10% points or normalization. Results A total of 104 patients (71 men, 69%; 72 probands) with definite TTNtv-DCM were included. The mean age at DCM diagnosis was (mean±SD) 45±13 years (43±13 for men; 49±14 for women, p<0.04) and median follow-up was 8.1 years. The mean LVEF was 28±13% at time of diagnosis (26±12% for men; 30±13% for women, p=0.173). During follow-up, 31 patients (30%; 24 men) died or needed HTX/LVAD. Medical therapy was associated with LVRR in 79% of patients 3.6 years after diagnosis. LVRR was maintained long-term in 64% of patients. Women had a better response to medical therapy compared to men (mean LVEF increase 19%; vs 15% in men, p<0.04). Atrial fibrillation/flutter was observed in 40% of patients and ventricular arrhythmias in 23% of patients. Men had an earlier occurrence of both supraventricular and ventricular arrhythmias (p=0.005) with half of the men having experienced an arrhythmia at the age of 54 years. Freedom from arrhythmias with age Conclusion TTNtv leads to a DCM phenotype associated with a marked gender-difference in age at DCM diagnosis and high burden of both supraventricular and ventricular arrhythmias. Importantly, the DCM-TTNtv phenotype was associated with a high degree of reversibility of systolic function following medical therapy.

Mitral regurgitation due to bileaflet prolapse and ischemic causes can be difficult to repair. Midterm experience of the Alfieri edge-to-edge repair as an alternative to valve replacement is reported. Twenty-six patients with severe mitral regurgitation underwent the Alfieri repair between January 1998 and December 2000 (group 1); 15 cases were due to bileaflet prolapse and 7 were of ischemic origin. During the same period, valve replacement was performed in 36 patients (group 2), 20 of whom had similar indications. Follow-up was complete to a mean of 15 months (range, 1–28 months). There was no early death in either group. During follow-up, there was no reoperation in group 1, while 2 patients in group 2 required reoperations due to prosthetic valve endocarditis. There were 4 major thromboembolic or bleeding events in group 2, and none in group 1. All patients in group 1 had trivial to mild mitral regurgitation on follow-up echocardiography. The mean mitral valve gradient was significantly higher in group 2 compared to group 1 (7.2 versus 3.2 mm Hg, p = 0.001). The edge-to-edge repair is associated with good early and midterm results. Long-term follow-up is required to evaluate the durability of this technique.
