Abstract Funding Acknowledgements Type of funding sources: None. Introduction Discharge after overnight hospital stay is standard procedure in patients submitted to elective atrial fibrillation (AF) ablation. Taking into consideration the low rate of cryoablation procedure complications could the same day discharge be an option? Purpose To access the safety of same day discharge of patients submitted to AF cryoablation. Methods Single-center retrospective study of consecutive pts admitted to elective AF cryoablation in a tertiary center between February 2017 and November 2020. Patients were divided into two groups: same day discharge and next day discharge. Only patients submitted to ablation until 4 p.m. were included. Complication rates were obtained up to six months after the procedure. Complications were defined as death, pericardial tamponade, hematoma requiring evaluation and/or intervention, major bleeding requiring transfusion, hospital admission related to the procedure. Results One hundred fifty-four pts were included, with a mean age of 61 ± 10.9 years, 66.2% were males, 18.2% with diabetes, 65.6% with dyslipidemia, 77.9% with hypertension, 10.4% with chronic kidney disease KDIGO stage 3 or more. Median follow-up of 436 (IQ 178 – 729) days. Most of the pts had paroxysmal (73.4%) and persistent short duration AF (23.4%). Sixty-two pts (40.3%) were early discharged and there were no differences between the two groups regarding epidemiological and clinical characteristics (p = NS). A very low rate of complications in both groups was observed, occurring in 6.5% of pts with early discharge and in 8.7% of pts in overnight stay, without statistical significance between the two groups (p = 0.61). The most frequent complications were local hematoma (5 pts, 2 in early discharged group), pericardial effusion (3 pts, all in overnight stay), femoral pseudo-aneurism (2 pts, 1 in each group) and arteriovenous fistula (1 pt in overnight stay group). The type of complications did not differ between the two groups (p = 0.51). Two pts died during the follow up, unrelated with the procedure. In addition, no difference in success rate and arrhythmic recurrence was observed between the two groups. (p = NS) Conclusion Our study suggests that is safe to early discharge pts submitted to AF ablation, reducing the hospital stay length in selected pts. Larger studies are needed to confirm this data before routine implementation of this strategy.

Abstract Introduction The COVID-19 pandemic provoked a change to normal surgical practice and led to a higher proportion of acute appendicitis (AA) patients being treated conservatively with antibiotics. We aim to analyse patients presenting with AA during the first wave of the pandemic, comparing surgically and conservatively managed patients. Method All patients presenting to our centre with AA between March and July 2020 were included. Six-month follow-up data was collected retrospectively using electronic records. Patients were categorised into surgically and conservatively managed groups. The primary outcome was the complication rate (post-operative complications vs failure of antibiotic treatment) and the secondary outcome was length of hospital stay. Results Fifty-seven patients (n = 57) were admitted with AA, 45.6% (n = 26) managed conservatively compared to 54.4% (n = 31) treated surgically. Higher complication rates were observed amongst the conservatively managed group, although not statistically significant (16% vs 35%; p = 0.131). There was no significant difference in length of hospital stay observed between the two groups (surgical: median, 2; interquartile range, 2-3 vs conservative: median, 3; interquartile range, 2-4). White cell count (WCC) and Alvarado score were higher on admission in the surgical group with statistical significance (p = 0.012 and p = 0.028 respectively). Conclusions Stratification criteria, such as Alvarado score and WCC may identify patients more suitable for conservative management. Longer term follow-up will be carried out, which may alter complication rates in either group. We suggest all patients treated conservatively should undergo computerised tomography (CT) to exclude complicated appendicitis. Further UK-based studies will add to the evidence-base surrounding management of AA during the COVID-19 pandemic.

Abstract Funding Acknowledgements Type of funding sources: None. Introduction Advances in the immediate management of ST elevation myocardial infarction (STEMI) have led to a dramatic decline in mortality and reduction in hospital length of stay (LOS). We analysed the prognostic value of selected risk models in STEMI treated with primary percutaneous coronary intervention (PPCI) and to identify additional parameters to strengthen risk scores in categorizing patients for safe early discharge and to identify parameters prolonging hospital stay. Purpose To assess parameters and risk scores to categorize patients for safe early discharge following STEMI and to assess the composite of death, MI, unstable angina (UA), stroke, unplanned hospitalization at the end of 30 days, 6 months and at 1year follow up. Methods The study included 222 patients, who were diagnosed as STEMI, treated with successful pPCI. The risk scores like TIMI score, GRACE score, ZWOLLE score, CADILLAC score were calculated for all patients from the baseline clinical data collected on admission. Routine blood investigations along with Brain natri-uretic peptide (BNP) were done for all patients. The entire cohort was divided into three groups on the basis of length of stay: ≤3 days (n = 150), 4–5 days (n = 47), and >5 days (n = 25). All-cause mortality and major cardiovascular events (MACEs) were assessed up to 1 year. Results The mean age group (yrs) of the study population was 53.92 ± 12.9. Patients in LOS <3 days had a mean age (yrs) of 52.41 ± 11.74, patients in LOS 4-5 days group had 54.19 ±13.59 and patient with LOS >5 days had 62.52 ± 15.32. The most important parameters that predicted hospital stay in our study are BNP levels OR: 1.003, 95% CI: 1.002-1.004, P < 0.001, GRACE score OR: 1.02 ,95% CI: 1.01-1.03, P < 0.001, TIMI score OR: 1.35, 95% CI: 1.18-1.55, P = 0.007, ZWOLLE score OR: 1.26, 95% CI: 1.16-1.37, P < 0.001, CADILLAC score OR: 1.24, 95% CI; 1.15-1.3: P < 0.001. 32 (14.4%) patients expired in the study population. 36% patients of LOS >5 days expired in 1year follow up with maximum mortality in the first 6 months. 56% of the patients in LOS > 5 days had an adverse cardiac event in 1 year follow up. Patients in LOS >5 days had increased event rates in 30 days,6 months and in 1 year follow up. Patients with LOS 4-5 days (30%) had increased event rates than patients in LOS < 3 days (19%).Unadjusted Kaplan Meir survival curves for 1 year mortality among hospital survivors showed a significant increase in mortality at 6 months in length of stay> 5 days group. (P value < 0.001). CONCLUSION Long hospital stay after PCI among patients with STEMI was associated with increased long-term all-cause mortality. Addition of BNP to this risk scores can better predict the course of hospital stay and adverse clinical outcomes in follow up. Long hospital stay may be used as a marker to identify patients at higher risk for long-term mortality. Abstract Figure. Kaplan meir survival curve

Long Term Experience

Objective This retrospective study presents the long-term results of catheter-directed foam sclerotherapy of the great saphenous vein. Method From January 2003 to June 2017, 277 patients with varices and great saphenous vein incompetence were treated with echo-guided foam sclerotherapy. Forty-six patients were treated with long-catheters guided by foam sclerotherapy. Foaming was carried out with sodium-tetra-decyl-sulphate. Results Results were examined in the two groups: A (long-catheters) and B (other procedures). The median overall follow-up was 52.1 months. In the A-group, the complete occlusion rate was 34/46 pts (73.9%) and partial occlusion was 10/46 (21.7%). In the B-group, respectively, 130/231 (56.2%) and 90/231 (38.9%). Comparisons between groups were statistically significant (p = 0.023; p = 0.021). Failures involved, respectively, 2/46 (4.3%) and 11/231 (4.7%) with no statistical significance. The complication rates were similar in the two groups. Conclusions In this long-term experience (median follow-up exceeding four years), foam-guided sclerotherapy of the great saphenous vein with a long-catheter turned out to be more effective than the usual foam-guided sclerotherapy.

Category: Bunion, Midfoot/Forefoot Introduction/Purpose: Hallux valgus is a complex deformity of the great toe and is a major cause of pain for patients. Despite the variety of techniques, traditional osteotomies often do not address rotational deformities. A novel biplanar plating system was used to perform correction of metatarsal rotation at our institution starting in 2017. The purpose of this study was to determine the correction of rotational deformity and of radiographic parameters, maintenance of this correction (versus recurrence of hallux valgus), complication rates and patient-reported objective survey scores. We sought to determine prognostic factors for successful correction, including age, gender, and time of surgery. Methods: By retrospective chart review, we identified all patients treated by the novel biplanar plating at our institution. We recorded patient demographics, pre-operative range of motion and maltracking, surgical details, operative complications, and any subsequent surgery. Imaging was reviewed at pre-operative and post-operative visits to approximate the hallux valgus angle (HVA), intermetatarsal angle (IMA), and tibial sesamoid position (TSP). Outcome scores (AOFAS, FAAM, SF12 PCS and MCS) pre- operatively and post-operatively at 3 months, 6 months and 12 months were also recorded. The changes in these radiographic parameters and scores were then computed and analyzed to determine if there was an improvement with surgery. Results: Fifty-seven procedures (in 55 patients) were performed and evaluated. There were 8 complications and average follow- up time was 27.1 weeks (+13.8 weeks). Older age was significantly associated with more complications (p = 0.018). Gender and time of surgery did not show any significant association with complications. Radiographic parameters including HVA, IMA, and TSP were analyzed. At 3 and 6 months post-operatively, these parameters were significantly reduced from pre-operative values. At 12 months, there was a trend towards significant reduction (p values of 0.06, 0.06, and 0.053 respectively); however, there were fewer patients who maintained follow-up during this period. The Outcome scores showed improvement post-operatively, but only the AOFAS score showed statistical significance at 3 and 6 months. Conclusion: Although statistical analysis was limited due to our population size and the retrospective nature of the study, there was an overall improvement in both radiographic parameters and clinical outcome scores. Older patients are also at higher risk of complications. Malrotation correction with this biplanar plating system is a novel technique and does require meticulous training. With continued expansion of our patient database and further longitudinal analysis, we hope to determine not only if correction is maintained over time, but also if the steepness of the learning curve affects the number of complications earlier versus later in each individual surgeon’s experience.

Background: Ankle fractures in patients with complicated diabetes have significantly increased the rates of complications and poorer functional outcomes when treated nonoperatively, and there have been only modest reductions when treated operatively. We hypothesized that the minimally invasive, robust construct that tibiotalocalcaneal fixation with an intramedullary nail offers would result in high rates of limb salvage, acceptable rates of complications, and less loss of function, in this difficult patient population. Methods: This was an institutional review board–approved retrospective study of 27 patients with complicated diabetes who underwent tibiotalocalcaneal nailing of their ankle fracture as a primary treatment without formal joint preparation. Patients with complicated diabetes were defined as having neuropathy, nephropathy, and/or peripheral vascular disease. The mean clinical follow-up was 888 days. Patients were screened for associated risk factors. Data were collected on surgical complications. The outcomes measured included length of hospital stay, loss of ambulatory level, amputation, and time to death. The mean age was 66 years with an average body mass index of 38 and hemoglobin A1c of 7.4. Six fractures were open. Results: The limb salvage rate was 96%. The average hospital stay was 6 days, and the mean time to weightbearing was 6.7 weeks. The fracture union rate was 88%. The surgical complication rate was 18.5%, with no instances of malunions, symptomatic nonunions, or Charcot arthropathy. Eight patients died by final follow-up (mean, 1048 days). An ambulatory level was maintained in 81% of the patients. Conclusion: With high limb salvage rates, relatively early weightbearing, maintained ambulatory level, and acceptable complication rates, we believe our technique can be considered an appropriate approach to increase the overall survivability of threatened limbs and lives in this patient population. Level of Evidence: Level IV, retrospective case series.

Abstract Background Due to the current COVID-19 pandemic, there is a realization for innovation in procedures and protocols to minimize hospital stay and at the same time ensure continued evidence-based treatment delivered to the patients. We present a same-day discharge protocol for transcatheter mitral valve repair (TMVR) using MitraClip under general anesthesia in a six-patient case series. This protocol aims to reduce length of hospital stay, thereby minimizing potential for nosocomial COVID-19 infections and to promote safe discharge with cautious follow-up. Case Summary Six patients with severe symptomatic mitral valve regurgitation underwent successful transfemoral mitral valve repair using standard procedures. Following repair, patients were monitored on telemetry in the recovery area for 3 hours, ambulated to assess vascular access stability and underwent post-procedural transthoracic echocardiogram to assess for any pericardial effusion or post-procedural prosthetic mitral stenosis. Conclusion Same day discharge after TMVR is possible when done cautiously with close Follow-up, can minimize hospital stay, improve resource utilization and reduce risk of nosocomial COVID-19 infection.

Background. Aortic valve stenosis accounts for 3–6% of congenital heart disease. Balloon aortic valvuloplasty (BAV) is the preferred therapeutic intervention in many centers. However, most of the reported data are from developed countries. Materials and Methods. We performed a retrospective single-center study involving consecutive eligible neonates and infants with congenital aortic stenosis admitted for percutaneous BAV between January 2005 and January 2016 to our tertiary center. We evaluated the short- and mid-term outcomes associated with the use of BAV as a treatment for congenital aortic stenosis (CAS) at a tertiary center in a developing country. Similarly, we compared these outcomes to those reported in developed countries. Results. During the study period, a total of thirty patients, newborns (n = 15) and infants/children (n = 15), underwent BAV. Left ventricular systolic dysfunction was present in 56% of the patients. Isolated AS was present in 19 patients (63%). Associated anomalies were present in 11 patients (37%): seven (21%) had coarctation of the aorta, two (6%) had restrictive ventricular septal defects, one had mild Ebstein anomaly, one had Shone’s syndrome, and one had cleft mitral valve. BAV was not associated with perioperative or immediate postoperative mortality. Immediately following the valvuloplasty, a more than mild aortic regurgitation was noted only in two patients (7%). A none-to-mild aortic regurgitation was noted in the remaining 93%. One patient died three months after the procedure. At a mean follow-up of 7 years, twenty patients (69%) had more than mild aortic regurgitation, and four patients (13%) required surgical intervention. Kaplan–Meier freedom from aortic valve reintervention was 97% at 1 year and 87% at 10 years of follow-up. Conclusion. Based on outcomes encountered at a tertiary center in a developing country, BAV is an effective and safe modality associated with low complication rates comparable to those reported in developed countries.

Purpose: To compare the four-petal evisceration technique and the standard evisceration technique. Methods: In this retrospective, comparative case series study, sixteen charts of patients fulfilled the inclusion criteria and were were reviewed. Orbital implant exposition and complication rates between the two surgical techniques were evaluated. Results: A total of 16 eye of 16 patients fulfilled the inclusion criteria and were included in the analysis (eight in the four petal group and eight in the standard evisceration group). During postoperative follow-up there were no cases of implant exposure or migration in the four-petal group and two cases (25%) of implant exposure in the standard evisceration group. Exposed orbital implants dimension were both 16 mm and patients eviscerated for phtisis bulbi All surgeries were uneventful, and there were no serious complications during the study. Conclusion: Four petal evisceration technique seems particularly useful in patients with phtisis bulbi because it allowed the placement of an implant significantly larger than the standard technique with low rate of esposition.

OBJECTIVEFixed sagittal spinal malalignment is a common problem in adult spinal deformity (ASD). Various three-column osteotomy techniques, including the extended pedicle subtraction osteotomy (ePSO), may correct global and regional malalignment in this patient population. In contrast to the number of reports on traditional PSO (Schwab grade 3 osteotomy), there is limited literature on the outcomes of ePSO (Schwab grade 4 osteotomy) in ASD surgery. The objective of this retrospective study was to provide focused investigation of radiographic outcomes and complications of single-level lumbar ePSO for ASD patients with fixed sagittal malalignment.METHODSConsecutive ASD patients in whom sagittal malalignment had been treated with single-level lumbar ePSO at the authors’ institution between 2010 and 2015 were analyzed, and those with a minimum 2-year follow-up were included in the study. Radiographic analyses included assessments of segmental lordosis through the ePSO site (sagittal Cobb angle measured from the superior endplate of the vertebra above and inferior endplate of the vertebra below the ePSO), lumbar lordosis (LL), pelvic tilt (PT), pelvic incidence and LL mismatch, thoracic kyphosis (TK), and sagittal vertical axis (SVA) on standing long-cassette radiographs. Complications were analyzed for the entire group.RESULTSAmong 71 potentially eligible patients, 55 (77%) had a minimum 2-year follow-up and were included in the study. Overall, the average postoperative increases in ePSO segmental lordosis and overall LL were 41° ± 14° (range 7°–69°, p < 0.001) and 38° ± 11° (range 9°–58°, p < 0.001), respectively. The average SVA improvement was 13 ± 7 cm (range of correction: −33.6 to 3.4 cm, p < 0.001). These measurements were maintained when comparing early postoperative to last follow-up values, respectively (mean follow-up 52 months, range 26–97 months): ePSO segmental lordosis, 34° vs 33°, p = 0.270; LL, 47.3° vs 46.7°, p = 0.339; and SVA, 4 vs 5 cm, p = 0.330. Rod fracture (RF) at the ePSO site occurred in 18.2% (10/55) of patients, and pseudarthrosis (PA) at the ePSO site was confirmed by CT imaging or during rod revision surgery in 14.5% (8/55) of patients. Accessory supplemental rods across the ePSO site, a more recently employed technique, significantly reduced the occurrence of RF or PA on univariate (p = 0.004) and multivariable (OR 0.062, 95% CI 0.007–0.553, p = 0.013) analyses; this effect approached statistical significance on Kaplan-Meier analysis (p = 0.053, log-rank test). Interbody cage placement at the ePSO site resulted in greater ePSO segmental lordosis correction (45° vs 35°, p = 0.007) without significant change in RF or PA (p = 0.304). Transient and persistent motor deficits occurred in 14.5% (8/55) and 1.8% (1/55) of patients, respectively.CONCLUSIONSExtended PSO is an effective technique to correct fixed sagittal malalignment for ASD. In comparison to traditional PSO techniques, ePSO may allow greater focal correction with comparable complication rates, especially with interbody cage placement at the ePSO site and the use of accessory supplemental rods.
