RESUMEN
BACKGROUND: The length of waiting lists in Italy for outpatient cardiology investigations provided by the National Health System is a serious dysfunction. The shortage of physicians in hospitals makes it difficult to solve this problem by drawing on internal resources. The waiting list at Valduce Hospital in Como for outpatient echocardiographic examinations was 12 months at the beginning of 2018. Therefore, we experimented a new way to deal with this inefficiency. METHODS: Starting in February 2018, we have undertaken in Valduce Hospital a partnership between the Department of Cardiology and an external startup (Ecocardioservice LLC) which guarantees for outpatients on-site performance by sonographers of echocardiographic examinations that are subsequently reported remotely via telemedicine by experienced cardiologists. RESULTS: From February 12, 2018 to July 7, 2022, 20 782 examinations were carried out by this mode. The waiting list was reduced from 12 months to 15-20 days. A new diagnosis or a significant change in pre-existing pathology were detected in 3466 patients well in advance of previous timelines. In 5640 patients we found a known stable pathology. Of the 8926 patients with pathologic examination, 3706 patients were taken over by the Cardiology Department for subsequent investigations, possible hospitalization and, when necessary, interventional or cardiac surgical procedures on an elective basis in 2636 cases (71%) and on an urgent basis in 1070 cases (29%). CONCLUSIONS: In our experience, a system in which echocardiograms are performed on-site by sonographers and then reported in telecardiology by cardiologists outside the facility makes it possible to meet the demands of the local area and free up internal resources. This organization allowed to bring outpatients waiting lists for echocardiography back within acceptable limits and to intercept early a significant proportion of patients with need for further investigations or procedures.

BACKGROUND: Diffuse coronary artery disease treatment still remains a challenge for interventional cardiologists and cardiac surgeons. There are few data on full metal jacket (FMJ) stenting, especially with new-generation drug-eluting stents. We aimed to assess the efficacy and safety of FMJ with new-generation Zotarolimus-eluting stents (n-ZES). METHODS AND RESULTS: All patients who underwent FMJ with n-ZES (≥60mm stent length) in eleven Italian interventional centers participating in the Clinical Service® project were included in this analysis. The project population consisted of 120 patients and 122 lesions. Mean age was 67±10years and 95 (79.2%) patients were male. A chronic total occlusion was present in 34 lesions (27.9%). The number of stents implanted per lesion was 2.9±0.8, and the diameter of the stents was 3.0±0.5mm. Predilation and post-dilatation were performed in 107 (87.7%) and 92 (75.4%) patients, respectively. At 41±21month follow-up there were 2 patients with subacute definite stent thrombosis, 6 patients (5.0%) had cardiac death and 5 patients (4.2%) had non-fatal myocardial infarction. Seven patients (5.8%) underwent clinically-driven target lesion revascularization. Fourteen patients (11.7%) had at least one major adverse cardiac event. CONCLUSION: The treatment of diffuse coronary artery disease with FMJ stenting with n-ZES appears to be effective and safe. Late and very-late ST does not seem to be an issue and the rate of restenosis and of major cardiac adverse events after more than 3-year follow-up is rather low.

The prognosis for abdominal aortic aneurysm (AAA) rupture is poor. Long-term follow-up of population-based randomized trials has demonstrated that ultrasound (US) screening for abdominal aortic aneurysms (AAAs) measuring 3 cm or greater decreases AAA-related mortality rates and is cost-effective. We though to prospectively perform during a 26-month period a limited US examination of the infrarenal aorta in volunteers of both gender aged 60-85 years without history of AAA living in the area of Como, Italy. From September 2010 to November 2013 ComoCuore, a no-profit nongovernmental association, enrolled 1555 people (aged 68.8 ± 6.8 years; 48.6 % males). Clinical data and a US imaging of the aorta were collected for each participant. AAA was found in 22 volunteers (1.4 %) mainly males (2.5 % in males vs. 0.4 % in females p = 0.005). Overall, the prevalence of cardiovascular risk factors was higher in patients with vs. without AAA (mean 2.9 ± 3.0 vs. 1.4 ± 1.0 respectively, p < 0.0001). Independent predictors of AAA on multivariate analysis were age (OR 1.14, 1.06-1.22; p < 0.0001), male gender (OR 8.23, 1.79-37.91; p = 0.007), and both current (OR 4.98, 1.57-15.79; p = 0.007) and previous smoking (OR 2.76, 1.12-8.94; p = 0.03). Our study confirms the feasibility of one time US screening for AAA in a large cohort of asymptomatic people. Independent predictors of AAA were male sex, older age and a history of smoking. Accordingly to recent data the prevalence of AAA seems to be declining, maybe due to a reduction of smoking in Italy.

Sudden cardiac death in the young is a relatively uncommon but marked event usually related to congenital diseases or anomalies. Despite the prevalence of each condition being variable, most common causes include primary myocardial diseases and arrhythmic disorder, frequently with inheritance pattern. Sudden cardiac death is usually preceded by symptoms, thus making personal and family history fundamental for its prevention. Nevertheless, in more than 50% of cases, sudden cardiac death is the first manifestation of the disease. In this review, we describe the different causes of sudden cardiac death, their incidence, and currently used preventive strategies.

BACKGROUND: Syncope in patients with bifascicular block (BFB) is a common event whose causes might be difficult to assess. METHODS AND RESULTS: Prevention of syncope through permanent cardiac pacing in patients with bifascicular block (PRESS) is a multicenter, prospective, randomized, single-blinded study designed to demonstrate a reduction in symptomatic events in patients with bifascicular block and syncope of undetermined origin implanted with permanent pacemaker. Device programming mode (NASPE/BPEG code) at DDD with a lower rate of 60 ppm is compared with backup pacing at DDI with a lower rate of 30 ppm. The end point consisted of (1) syncope, (2) symptomatic presyncopal episodes associated with a device intervention (ventricular pacing), and (3) symptomatic episodes associated with intermittent or permanent atrioventricular block (any degree). One hundred one patients were enrolled and randomized. Primary end point events at 2 years were observed in 23 patients, with a significant lower incidence in the study group (hazard ratio, 0.32; 95% confidence interval [CI], 0.10-0.96; P=0.042). Reduction of any symptoms, associated or not with device intervention, was superior in DDD60 compared with DDI30 (hazard ratio, 0.4; 95% confidence interval, 0.25-0.78; P=0.0053). Fourteen patients developed other rhythm diseases and met class I indication for pacing. The annual incidence of rhythm disease development was 7.4%. CONCLUSIONS: In patients with bifascicular block and syncope of undetermined origin, the use of a dual chamber pacemaker programmed to DDD60 led to a significant reduction of syncope or symptomatic events associated with a cardioinhibitory origin, compared with DDI30 programming. Symptoms associated with a new onset of rhythm disease were found in 15% of the population at 2 years.

AIMS: The aim of this prospective study was to assess the diagnostic value of a sublingual nitroglycerin (NTG) potentiated head-up tilt (HUT) testing protocol in children with unexplained syncope. METHODS AND RESULTS: One hundred and sixty-four consecutive paediatric patients with syncope of unknown origin and no evidence of organic heart disease (115 female, mean age 13 +/- 3 years) and 29 control children underwent a sublingual NTG-potentiated tilt testing protocol. Paediatric patients and controls were tilted at 60 degrees for 20 min and, if no symptom occurred, for other 15 min after sublingual 400 mug spray NTG administration. During the drug-free phase of the test, 13 patients (8%) and no controls had a positive response. After drug administration, a positive response occurred in another 88 patients (55%) and in four controls (14%), whereas an exaggerated response was observed in nine patients (5%) and in four controls (14%). Thus, the positive rate and specificity of sublingual NTG HUT test in children were 63 and 86%, respectively. No relevant adverse events were observed during the test. CONCLUSION: Tilt testing potentiated with sublingual NTG has proved to be effective and safe in unmasking the neurally mediated origin of unexplained syncope in children. The NTG challenge greatly increased the positive rate of passive tilt, with a small decrease in specificity.

Recurrent neurally mediated syncope represents a common clinical event and a therapeutic challenge. Recently tilt training has been proposed for the treatment of recurrent neurally mediated syncope. To evaluate the efficacy of tilt training in preventing tilt-induced syncope and its feasibility, this controlled, randomized study was undertaken. Sixty-eight consenting patients (25 males and 43 females, mean age 40 +/- 19) with recurrent neurally mediated syncope and 2 consecutive positive nitroglycerin-potentiated head-up tilt tests were randomized to tilt training (35 patients) or no treatment (controls, 33 patients). The tilt training programme consisted of daily 30-min sessions of upright standing against a vertical wall 6 days a week for at least 3 weeks, until a reevaluation tilt test (3 patients of both groups dropped out). On this third head-up tilt test, 19 (59%) of 32 tilt trained patients and 18 (60%) of 30 controls still had a positive test. Treated patients performed a mean number of 15 +/- 7 sessions (median 16) and only 11 patients (34%) did all the programmed sessions. Only 1 patient (3%) discontinued treatment because of intolerance, while all other patients did not perform tilt training adequately, because of poor compliance. Thus, in our study tilt training was not effective in reducing tilt testing positivity rate in patients with neurally mediated syncope. Because of poor compliance, tilt training appears to be a feasible treatment only for highly motivated patients, but not for the majority of patients with recurrent neurally mediated syncope.

Myocardial involvement is a common finding in patients with Duchenne-type muscular dystrophy (DMD). Nevertheless, the prognostic values of standard electrocardiogram (ECG), ventricular arrhythmias, ventricular late potentials (LPs), and left ventricular (LV) systolic dysfunction have not been extensively investigated. Eighty-four patients with DMD (aged 18.6 +/- 4.8 years) underwent standard and signal-averaged electrocardiography, 24-hour Holter monitoring, and echocardiography. The prevalence of electrocardiographic abnormalities, frequent ventricular premature complexes, LPs, and LV systolic dysfunction was 71%, 32%, 28%, and 35%, respectively. Median follow-up was 76 months (range 5 to 106). The mortality rate in the follow-up period was 27%. The typical DMD electrocardiographic alterations, ventricular arrhythmic pattern, and LPs were not predictors of mortality. In contrast, the presence of LV systolic dysfunction detected on echocardiography was a powerful predictor of mortality in the follow-up period (p = 0.013, hazard ratio 3.14, 95% confidence interval 1.27 to 7.79). Thus, echocardiographic assessment of LV systolic dysfunction provides prognostic information in patients with DMD. Electrocardiographic alterations, ventricular arrhythmias, and LPs have no prognostic value in predicting mortality in these patients.
