Abstract Funding Acknowledgements Type of funding sources: Private grant(s) and/or Sponsorship. Main funding source(s): Malta Heart Foundation and Beating Hearts Background Little is known about the prevalence and clinical relevance of an isolated short PR interval in young individuals. Objectives To explore the PR interval in adolescent athletes and non-athletes and determine possible association with sex, age, ethnicity, athletic ability and sporting discipline. Methods Between 2017-2018, school children aged 14-17 years were invited to participate in a National cardiac screening programme comprised of a health questionnaire and a resting 12-lead ECG. An athlete was defined as an individual participating in >4 hours/week of organised sports. Sport disciplines were categorised as skill, power, mixed and endurance. A short PR interval was defined as <120ms. Results A total of 1619 (61.0%) non-athletes and 1036 (39.0%) athletes  (median age 15 years, 50.5% females, 93.0% Caucasian) participated in the screening program. Most athletes participated in mixed sports (62.2%). The mean PR interval was shorter in non-athletes compared to athletes (136.65 ± 19.00ms vs 139.93 ± 19.86ms p < 0.001) and in females compared to males (135.98 ± 18.39ms vs 139.93 ± 20.20ms, p < 0.001). An isolated short PR interval was present in 405 (15.3%) individuals. Associated pre-excitation was present in an additional 5 cases (0.2%). A short PR interval was commoner in females (18.7% vs 11.7%, p < 0.001) and in non-athletes (16.6% vs 13.2%, p = 0.020). Age (p = 0.657) and ethnicity (p = 0.115) did not influence the presence of a short PR interval. The presence of a short PR interval in adolescent athletes was independent of the sporting discipline category (p = 0.071), in both males (p = 0.400) and females (p = 0.233).  The absolute PR interval did not differ significantly between sporting categories (p = 0.065),  in both genders (males, p = 0.202, females, p = 0.279). Symptoms that were suggestive of arrhythmias were present in similar proportions of individuals with short and normal PR intervals (18.8% vs 17.1%, p = 0.393).  Conclusion An isolated short PR interval was a frequent finding in this cohort, with a predilection for females and non-athletes. The high frequency of short PR in young individuals suggests that in the absence of pre-excitation or symptoms, further evaluation is not warranted. Long-term follow-up studies may further elucidate the clinical relevance of this phenomenon.

Long Term Follow Up

A screening program for abdominal aortic aneurysm (AAA), inviting 65-year-old men, was started in Stockholm in 2010 (2.3 million inhabitants). The aim was to present a long-term follow-up of men participating in screening, as well as AAA repair and ruptures among nonparticipants. Demographics were collected for men with screening detected with AAA 2010 to 2016 (n = 672) and a control group with normal aortas at screening (controls, n = 237). Medical charts and regional Swedvasc (Swedish Vascular registry) data were analyzed for aortic repair for men born 1945 to 1951. Ultrasound maximum aortic diameter (AD) as well as Aortic Size Index (ASI) was recorded. Participation was 78% and prevalence of AAA was 1.2% (n = 672). Aortic repair rates correlated with high ASI and AD. During the study period, 22% of the AAA patients were treated with the elective repair; 35 men in surveillance died (5.2%), non-AAA-related causes (82.9%) dominated, followed by unknown causes among 4 (11.4%), and 2 (5.7%) possibly AAA-related deaths. Abdominal aortic aneurysm rupture rate was higher among nonparticipants (0.096% vs 0.0036%, P < .001). The low dropout rate confirms acceptability of follow-up after screening. The efficacy is shown by the much higher rupture rate among the nonparticipating men.

Long Term Follow Up

Objective: To evaluate the clinical relevance of neovascularisation at the saphenous ligation site. Design: Long-term follow-up after previous varicose vein surgery in a single patient group. Setting: Vascular clinic of a university hospital. Patients: Eighty-two patients (106 limbs) with a mean follow-up period of 56 months after correct saphenous ligation were submitted to duplex scanning. Intervention: Clinical assessment and colour duplex scanning of all the operated limbs. Reintervention in 15 limbs with perioperative evaluation of recurrent veins. Main outcome measures: Limbs with and without recurrent varicose veins were classified according to the degree of neovascularisation: grade 0 = no new communicating veins, grade 1 = tiny new vein with diameter <4 mm, grade 2 = new communicating vein with diameter >4 mm and pathological reflux. On reintervention the presence of neovascular veins at the site of the previous ligation was checked. Results: In 68 limbs without recurrent varicose veins, grade 0 was observed in 50 limbs (74%), grade 1 in 12 limbs (18%) and grade 2 in six limbs (9%). In 38 limbs with recurrent varicose veins, grade 0 was diagnosed in eight limbs (21%), grade 1 in four limbs (11%) and grade 2 in 26 limbs (68%). In 15 limbs with recurrent varicose veins and grade 2 neovascularisation, reintervention confirmed the duplex findings. Conclusions: The presence of grade 2 neovascularisation was associated with the recurrence of varicose veins, suggesting a causal relationship.

Where suitable, dental implants are praised as a method of providing fixed solutions with good longevity, and providing greatly improved retention for removable prostheses, resulting in increased levels of patient satisfaction and quality of life. However, with increasing evidence of long-term follow-up, there is a growing recognition of the susceptibility of dental implants to peri-implant diseases; peri-mucositis and peri-implantitis. This paper discusses the features of peri-implant disease and important aspects of assessment criteria. CPD/Clinical Relevance: This paper highlights the importance of supportive maintenance care for patients with dental implants, as well as the features and assessment of peri-implant disease.

Long Term Follow Up

Abstract Funding Acknowledgements Type of funding sources: Public hospital(s). Main funding source(s): Hospital Puerta del Mar OBJECTIVES AND METHODS We aim to evaluate the long-term clinical and intravascular outcomes inACS patients treated with Magnesium-Based Bioresorbable Scaffold(MgBRS).Exclusion criteria:left main disease,bifurcations,ostial lesions,severe tortuosity and calcification,long lesions,high thrombus burden,haemodynamic instability,oral anticoagulants,contraindication to dual-antiplatelet therapy.Primary endpoint was the device-oriented composite end-point(DOCE):cardiac death,target vessel myocardial infarction,and target lesion revascularization(TLR).RESULTS:Between Dec2016 to Dec2018,90patients with ACS underwent PCI with MgBRS.46%patients presented with STEMI.Mean age55.9 ± 9.9,75.6%males and64.4%smokers.OCT was performed in 62patients.Mean scaffold length21.27 ± 7.7mm,mean diameter3.31 ± 0.24mm.15 patients required a second overlapped stent.There were 7complications:5edge dissection;1catheter-induced ostial dissection and 1case of slow-flow.Post-PCI OCT showed in-scaffold area stenosis of3.49 ± 21.29%.At 15months,diameter stenosis was31.95 ± 26.14%and restenosis was observed in 10cases(21.7%).Mean scaffold area shrinked from baseline(7.57 ± 1.77mm2)to15-month follow-up(6.13 ± 2.20mm2).The main mechanism of restenosis was scaffold collapse.DOCE was observed in 13.3%of patients.2patients with target-vessel myocardial infarction due to stent thrombosis.1case had recurrent angina at2weeks because of stent fracture and proximal edge dissection.9cases presented restenosis at different time-points.CONCLUSIONS:MgBRS is feasible in patients presenting ACS.At long-term follow-up,further development is needed to help to resolve these drawbacks
