Abstract
Abstract
Background
The UNTOUCHED study (designed in 2017 and published in 2021) demonstrated high success rate for termination of ventricular arrhythmias, and very low inappropriate shock rate in subcutaneous implantable cardioverter-defibrillator (S-ICD) recipients. The prescribed device programming included a conditional zone between 200 and 250 beats per minute (bpm) with discrimination algorithms employed to avoid delivering inappropriate shocks in this range, and a shock zone based on the rate alone for arrhythmias >250 bpm. Whether these results influenced clinical practice is unknown.
Methods
We assessed the programming at implantation and changes in programmed parameters at follow-up (≥1 year) in a cohort of S-ICD recipients enrolled in the Rhythm Detect registry at 56 centers.
Results
From 2013 to 2021, 1521 consecutive patients (aged 49±15 years; 79% male, 52% dilated cardiomyopathy, 31% arrhythmic syndromes, 16% hypertrophic cardiomyopathy) were analyzed. At implantation, the programmed sensing vector was the Primary in 59% of patients, the Secondary in 35%, the Alternate in 6%. At follow-up, the sensed vector was changed in 13% of patients. The programmed conditional zone cutoff was set to 200 [200–220] bpm (median [25–75 percentile]), and the shock zone cutoff to 230 [210–250] bpm. At follow-up, the conditional zone cutoff was reprogrammed in 13% of patients, but the median value in the overall population did not change (200 [200–220] bpm; p>0.05). The shock zone cutoff was reprogrammed in 43% of cases, and the overall median value was 250 [230–250] bpm (p<0.001 versus implantation). Sorting patients by implantation date, we observed that in the first 764 patients (implanted ≤2017) the shock zone cutoff was set to 210 [210–230] bpm at implantation and to 240 [230–250] bpm at follow-up (reprogrammed in 66% of cases). While in patients implanted >2017, it was already set to 250 [230–250] bpm at implantation and to 250 [240–250] bpm at follow-up (reprogrammed in 20% of cases, p<0.001 versus ≤2017).
Conclusions
S-ICD programming parameters are rarely changed during follow-up (approximately 13% of patients). The only exception in clinical practice was the shock zone cutoff. Centers have begun to program high cutoffs in recent years. This happened at the time of implantation for new S-ICD recipients and at follow-up for pre-existing implants. This behavior is consistent with a substantial adoption of published trial findings and could contribute to reduce the incidence of inappropriate shocks in clinical practice.

Abstract
Abstract
Background
A previous randomized study (PRAETORIAN) demonstrated that the subcutaneous implantable cardioverter–defibrillator (S-ICD) was noninferior to transvenous ICD with respect to device-related complications and inappropriate shocks. However, that was performed prior to the widespread adoption of pulse generator implantation in the intermuscular (IM) space instead of the traditional subcutaneous (SC) pocket.
Purpose
To compare survival from device-related complications and inappropriate shocks between patients who underwent S-ICD implantation with the generator positioned in an IM position in comparison with a SC pocket.
Methods
We analyzed 1577 consecutive patients who had undergone S-ICD implantation from 2013 to 2021 and were followed up until December 2021. SC patients were propensity-matched with patients of the IM group, and their outcomes were compared.
Results
SC implantations were performed in 367 (23%) patients. These patients were propensity-matched with 367 IM patients. Intra-procedural complications were reported in 9 (2.5%) patients in the SC Group and 7 (1.9%) in the IM Group. During a median follow-up of 29 months, device-related complications were reported in 55 (7.5%) patients and inappropriate shocks were reported in 54 (7.4%) patients. The risk of the composite primary endpoint was lower in the matched IM Group than in the SC Group (unadjusted hazard ratio 0.67, 95% CI 0.45–0.99, p=0.042), while the risk of appropriate shocks was similar between groups (unadjusted hazard ratio 0.99, 95% CI 0.60–1.64, p=0.976). There was no significant interaction between generator positioning and variables such as gender, age, body mass index, ejection fraction and generation of the device.
Conclusions
In this experience, IM S-ICD generator positioning was superior to SC positioning in reducing device-related complications and inappropriate shocks.

Background
In December 2020, the subcutaneous implantable cardioverter-defibrillator (S-ICD) lead model-3501 was subject to a safety notification because of increased risk of fracture at a location just distal to the proximal sense ring. The manufacturer’s product performance report currently reports a lead survival probability of 98.8% at 45 months. However, no multicenter long-term performance information exists for this lead.
Purpose
Our aim was to assess the longevity of model-3501 leads and to compare it with that of the previous model-3401.
Methods
This analysis included consecutive patients who received an S-ICD with a model-3501 or a model-3401 lead at 66 Italian participating centers of the Rhythm Detect registry. A lead failed if it required extraction/replacement because of abnormalities suggestive of a structural defect, e.g. out-of-range impedance, nonphysiological electrical noise or ineffective therapy.
Results
From January 2013 to July 2021, 2403 patients were implanted and followed up (78% male, age 49±15years, ejection fraction 45±16%, body mass index 26±4Kg/m2). A 3501-model lead was used in 1697 patients and a 3401-model in 706 patients. During a median follow-up of 38 months [25th–75th percentile: 24-55], we detected 4 malfunctioning model-3501 leads and 2 model-3401 leads. After analysis of the returned leads by the manufacturer’s technical services, a single model-3501 lead failure was a fracture distal to the proximal ring electrode, as described in the manufacturer’s advisory letter. No deaths or permanent injuries occurred as a result of lead failures. The survival of 3501-model leads at 4 years was 99.5% (95% confidence interval, 99.0 to 99.9) compared with 99.9% (95% confidence interval, 99.6 to 100.0) of 3401-model leads (p=0.110). The cumulative occurrence rate of the 3501-model safety notification fracture was 0.1% (95% confidence interval, 0.0 to 0.3).
Conclusions
In this large multicenter analysis, the survival probability of model-3501 S-ICD leads was in line with that reported by the manufacturer, was not significantly lower than that of 3401-model leads (not affected by a safety notification), and still higher than that reported with transvenous leads. Although an enhanced electrode is now available, which addresses the potential for electrode body fracture, the present findings are reassuring and may have significant implications for the management of patients who have affected leads.

Abstract
Abstract
Aims
According to current guidelines, defibrillation testing (DT) for efficacy can be omitted in patients undergoing transvenous implantable cardioverter–defibrillator (T-ICD) implantation. DT is still recommended for patients at risk for a high defibrillation threshold (e.g. hypertrophic cardiomyopathy, arrhythmogenic right ventricular cardiomyopathy, right-sided implantations) and for ICD generator changes. Moreover, a class I recommendation remains to perform DT during the implantation of subcutaneous ICD (S-ICD). The aim of the present survey was to analyze the current practice of DT during T-ICD and S-ICD implantations in Italy.
Methods
In March 2021, an ad hoc questionnaire on the current performance of DT and the standard practice adopted during testing was completed by 72 operators at Italian centers implanting S-ICD and T-ICD.
Results
48 (67%) operators reported never performing DT during de-novo T-ICD implantations, while no operators perform it systematically. The remaining respondents perform it in specific cases: right sided implantations (54%), poor signal sensing (46%), secondary prevention patients (42%), arrhythmic syndromes (13%), hypertrophic cardiomyopathy (8%). DT is never performed at T-ICD generator change. At the time of de-novo S-ICD implantation, DT is never performed by 9 (13%) operators and performed systematically by 48 (66%). The remaining operators perform DT in cases of: secondary prevention patients (73%), sub-optimal S-ICD placement (33%), non-compromised ejection fraction (33%) or obese patients (7%). DT is not performed at S-ICD generator change by 92% of operators. DT is conducted by delivering a first shock energy of 65J by 60% of operators, while the remaining 40% test lower energy values. The most frequently reported conditions for revising the system at the end of de- novo implantation procedure is high shock impedance (54%) and sub-optimal S-ICD placement or high PRAETORIAN score (50%). With adequately low shock impedance and optimal system placement, 37% of operators would accept a defibrillation margin <15J.
Conclusion
In current clinical practice, the vast majority of operators omit DT at T-ICD implantation, even when still recommended in the guidelines. DT is also frequently omitted at S-ICD implantation. We also report a wide variability among operators in the procedures followed during DT and in the criteria applied for defining the procedural success.

Background
Defibrillation efficacy testing (DT) is recommended at implantation of subcutaneous implantable cardioverter–defibrillators (S-ICD). However, prior works found that adherence to this recommendation is declining in clinical practice.
Purpose
To compare survival from all-cause death and first ineffective shock (primary endpoint) and the composite of all-cause death, ineffective shock, inappropriate shock and device-related complication (secondary endpoint) between patients who underwent DT and those with omitted DT.
Methods
We analyzed 1652 consecutive patients who underwent S-ICD implantation in 60 Italian centers from 2013 to 2019.
Results
DT was not performed in 325 (20%) patients (no-DT patients). As compared with the DT group, these patients were older (51 ± 16 vs. 48 ± 15 years; p < 0.01) and had lower ejection fraction (37 ± 16% vs. 46 ± 16%; p < 0.01). The 325 no-DT patients were propensity matched with 325 patients of the DT group. During a median follow up of 19 months, 27 (4.2%) patients died for any-cause. During follow-up, 34 (5.2%) patients received appropriate shocks to treat discrete episodes of VT/VF. The first shock was effective in 30 out of 34 patients (88%), whereas a second shock was required to terminate VT/VF in 3 patients and a third shock in the last one. The primary endpoint occurred in 31 (4.8%) patients, and the risk was not significantly increased in the no-DT cohort (HR = 1.26, 95%CI:0.62-2.55, p = 0.522). Inappropriate shocks were reported in 36 (5.5%) patients and device-related complications in 25 (3.8%) patients during follow-up. Survival from the composite secondary endpoint was comparable between groups (HR = 0.86, 95%CI:0.57-1.32, p = 0.500).
Conclusions
Our data confirmed that DT is frequently omitted in current clinical practice, especially in older patients with worse systolic function. A strategy that omits DT did not appear to compromise the effectiveness of the S-ICD and no additional risk seems associated with DT omission at a mid-term follow-up. These data suggest that routine DT at S-ICD implant might not be necessary. Randomized trials are needed to confirm this finding.

Background To ensure effective defibrillation with the subcutaneous implantable cardioverter defibrillator (S-ICD), both the lead and the generator must be adequately positioned extrathoracically. We assessed the long-term adequacy of the S-ICD system position and its stability in a group of patients who received the S-ICD by means of the two-incision intermuscular technique.
Methods The PRAETORIAN score uses chest radiography to provide feedback on S-ICD positioning, and identifies patients with high defibrillation thresholds. We compared radiographs taken immediately after implantation and on 12-month follow-up examination.
Results We analyzed data from 38 patients with the S-ICD generator positioned in an intermuscular pocket. The median PRAETORIAN score was 38 [25th to 75th percentile: 30 to 60]. Two (5%) patients had a score of 90 (intermediate risk of conversion failure). The thickness of the adipose tissue between the coil and the sternum was ≤1 coil width in 72% of patients, the generator was on, or posterior to, the midline in 94% of patients, and the amount of fat tissue between the generator and the thoracic wall was less than the generator width in 78% of patients. No generator or electrode dislodgments were detected on analyzing radiographs collected at the 12-month visit. In all patients, assessment of the PRAETORIAN score confirmed the values calculated on post-implantation analysis. During follow-up, no ineffective therapies, sudden cardiac or device-related deaths occurred.
Conclusions The position of the S-ICD system implanted using the two-incision intermuscular technique was adequate at the time of implantation and remained stable after 12 months.

Background
Implantable Cardiac Monitors (ICM) provide continuous long-term heart rhythm monitoring. The new ICM BIOMONITOR III / IIIm (BM III) is provided with a single-step insertion tool.
Purpose
To report on the insertion procedure of the BM III in a large real-world patient population.
Methods
The BM III combines a low cross-section (4.5 x 8.5 mm) with an extended ICM length (77 mm, including flexible antenna). It is inserted into subcutaneous tissue with an ‘injection’ tool that forms the pocket and delivers the device in a single step. We report results of the insertion procedure from a pooled data set from the BIO|CONCEPT BM III (completed) and the BIO|MASTER BM III and BIO|STREAM-ICM (ongoing) studies.
Results
From 54 investigational sites in 11 countries, 455 insertions were reported (including 39 BM IIIm). The patients were 63 ± 16 years old, had a BMI of 27.6 ± 5.4, and 43% were women. The indications were syncope or pre-syncope (57%), cryptogenic stroke (23%), management of AF (11%) or other (9%). Insertions took 1.7 ± 1.8 minutes until removal of the insertion tool, 4.7 ± 3.4 minutes until wound closure, and 7.1 ± 5.6 minutes including wound cleaning. The wound was sutured (79%) or closed with staples (10%) or adhesive strips (10%). General anaesthesia was used in 8% of the patients and antibiotic prophylaxis in 50% (44% systemic and 6% local). Insertions took place in the catheter laboratory (62%), operating theatre (22%) or in a consultation room (16%) without specific precautional equipment.
The insertion site was parallel to the heart"s long axis (56%), parasternal (39%), in the 2nd/3rd intercostal space (3.5%), axillary (0.9%) or at the clavicula (0.7%). The device was repositioned in one case (0.2%). 13 adverse events were reported in connection to the insertion procedure. 5 cases of device pocket bleeding or hematoma occurred. In 5 further cases, the device migrated, posing the risk of extrusion, or actually extruded. Three of these cases used only adhesive strips or no wound closure at all. In two cases, an incorrect usage of the incision tool and substantial subcutaneous fatty tissue may have contributed. One device was damaged by a 200 J defibrillation shock with a shock electrode placed over the device. One patient suffered from dyspnoea, possibly due to psychogenic hyperventilation. One patient had a vasovagal syncope due to pain after an insertion with insufficient local anaesthesia. No infections were reported until the day of analysis, which was more than 30 days after insertion in 92% of all cases.
Conclusion
The new BM III was inserted in typically less than 5 minutes until wound closure. A relevant number of insertions took place in a consultation room. Prophylactic antibiotics may be unnecessary, because no pocket infections were reported, although no antibiotic prophylaxis was used in one half of all cases (N = 229). In summary, the insertion with the new tool is fast and has a low risk of complications.

Background
A two-incision technique, in association with inter-muscular positioning of the subcutaneous defibrillator (S-ICD), is now the most frequently adopted implantation approach in Europe. Ultrasound-guided serratus anterior plane block (SAPB) has been proposed in order to provide anesthesia/analgesia during S-ICD implantation.
Objective
We performed a case-control analysis in which a standardized SAPB approach was compared with the typical local anesthesia and sedation approach.
Methods
91 consecutive patients underwent implantation of an S-ICD with the SAPB approach for anesthesia/analgesia at 10 centers. The control group consisted of 55 consecutive patients who underwent S-ICD implantation with standard local approach.
Results
The mean procedure duration was 59 ± 15min in the SAPB group and 76 ± 23min in the control group (p < 0.001). No operative complications were reported in either group. During the procedure, 79 (87%) patients in the SAPB group and 25 (46%) patients in the control group (p < 0.001) remained awake. Lower values of pain intensity at the device pocket (p = 0.005) and the lateral tunneling site (p = 0.046) were reported in the SAPB group. The difference in static (p = 0.002) and dynamic (p = 0.007) pain intensity between the groups persisted at 1 hour, while no differences were observed 6 hours after the end of the procedure.
Conclusions
SAPB is feasible and effective in providing anesthesia/analgesia during S-ICD implantation. The procedures were successfully accomplished and no complications occurred in either group. However, SAPB was associated with lower pain levels, enabling the need for sedation to be reduced and more patients to remain awake. Moreover, it resulted in shorter procedure durations.

Abstract
Abstract
Introduction
The subcutaneous ICD (S-ICD) is a valid alternative to transvenous systems (TV-ICD) for the treatment of life-threatening arrhythmias, and the extravascular position of the lead allows a significant reduction of the risk of infection. Current guidelines recommend defibrillation threshold testing (DFT) at the time of S-ICD implantation (class I). Although randomised trials have proven the safety of TV-ICD implantation with no DFT, it is unclear whether such an approach could be adopted for S-ICD as well. The PRAETORIAN score, based on post-implantation chest X-ray, can accurately predict a high defibrillation threshold after S-ICD implantation. The aim of this retrospective multicentre study was to evaluate the efficacy and safety of S-ICD implantation with no DFT.
Methods
We enrolled 203 consecutive patients undergoing S-ICD implantation in six different centres between October 2012 and January 2019. It was left at discretion of the operator whether performing or not DFT at the time of the procedure. Baseline device settings were collected, and the PRAETORIAN score was retrospectively calculated whenever chest X-ray was available. Both remote or in-clinic device interrogation reports were systemically analysed, and all the shocks and arrhythmia episodes identified. All the patients provided consent form and ethical approval was obtained.
Results
The population (mean age 57.6 ± 14.2) was divided in two groups, based on whether DFT was performed at the time of the S-ICD implantation: 72 patients (35.4%) underwent DFT (DFT+ group), while 131 patients (64.5%) did not (DFT- group). In the DFT- group, mean LVEF was lower (32 ± 8% vs 42 ± 17%, p < 0.0001) and prevalence of diabetes mellitus and atrial fibrillation higher compared to the DFT+ group (27.5% vs 13.9%, p = 0.04 and 38.9% vs 19.44%, p = 0.007; respectively). In addition, the indication for S-ICD was more frequently primary prevention in the DFT- vs DFT+ group (70.8% vs 90.8%, p = 0.0004; respectively). No differences in terms of device programming were identified between the two cohorts. The PRAETORIAN score was significantly higher in the DFT- vs DFT+ patients (50 ± 26 vs 36 ± 18, p = 0.032; respectively). After a median follow-up of … months, we observed 5 appropriate shocks in 3 patients from the DFT+ group vs. 15 shocks in 8 patients from the DFT- group (p = 0.81). All the life-threatening arrhythmias were successfully recognised and treated by the device. DFT was complicated by pulseless electrical activity in one patient. One patient in the DFT- group suffered from an episode of ventricular tachycardia requiring a total of 4 shocks for being terminated. Six patients in the DFT- group died for non-arrhythmic causes. On the Kaplan-Meier analysis, cumulative survival was comparable between the two groups (log rank p value = 0.13).
Conclusions
This study suggests that implantation of S-ICD with no DFT might be reasonable. These results should be confirmed in prospective randomised trials.

Background
Currently, when an implantable-cardioverter defibrillator (ICD) lead becomes nonfunctional, a class IIa recommendation exists for either lead abandonment or for removal. The benefits of removal include creation of an access for insertion of a new lead. However, the subcutaneous ICD (S-ICD) does not require the insertion of any leads into the cardiovascular system, and may represent an additional option for patients not requiring pacing.
Purpose
To report outcomes associated with a strategy of lead abandonment and S-ICD implantation in the setting of lead malfunction.
Methods
We analyzed all consecutive patients who underwent S-ICD implantation after abandonment of malfunctioning leads and we compared outcomes with those of patients who underwent transvenous extraction and subsequent reimplantation of a single-chamber transvenous ICD (T- ICD).
Results
43 patients were implanted with an S-ICD after abandonment of malfunctioning leads, while in 62 patients extraction and subsequent reimplantation of a T-ICD. The two groups were comparable (Age 55 ± 16 vs. 54 ± 33years, BMI 26 ± 3 vs. 24 ± 4kg/m2, LVEF 43 ± 15 vs. 48 ± 8%). S-ICD defibrillation test success rate at implantation was 96% at 65J. In the extraction group, no major complications were reported during extraction, while the procedure failed and an S-ICD was implanted in 4 patients. During a median follow-up of 21 months, the rate of major complications was not higher in the S-ICD group than in the T-ICD group (HR 1.07; 95%CI 0.29–3.94; P = 0 .912; Figure), as well as the rate of minor complications (HR 2.13; 95%CI 0.49–9.24; P = 0 .238).
Conclusions
In case of ICD lead malfunction, extraction prevents potential long-term risks of abandoned leads, e.g. increased complications for a possible future mandatory extraction indication such as infection, and allows magnetic resonance imaging. Nonetheless in this series, the strategy of lead abandonment and S-ICD implantation appeared to be feasible and safe with no significant increase in adverse outcomes for patients not requiring pacing and may represent an option in selected clinical settings (very high risk or failed extractions, older patients, etc.). Longer follow-up studies are needed to fully understand the potential risks of lead abandonment.

Abstract
PURPOSE We summarize the literature and present our experience with genitourinary manifestations of the Klippel-Trénaunay syndrome, which can lead to challenging management problems. MATERIALS AND METHODS We report on 2 patients with genitourinary manifestations of the Klippel-Trénaunay syndrome and performed a MEDLINE review of the literature using the key words "Klippel-Trénaunay," "vascular malformation" and "genitourinary." RESULTS Genitourinary manifestations were cited in 18 articles, including 1,174 cases of the Klippel-Trénaunay syndrome, detailing the presentation and management of bladder, external genitalia and retroperitoneal involvement in the Klippel-Trénaunay syndrome. The overall genitourinary symptoms in patients with the Klippel-Trénaunay syndrome seem to occur in the more severe cases and usually involve cutaneous vascular malformations of the trunk, pelvis and genitalia. CONCLUSIONS Intra-abdominal and intrapelvic extension of the vascular malformations of the Klippel-Trénaunay syndrome frequently occurs concurrently with the lower abdominal, pelvic cutaneous involvement of the external genitalia, as in our 2 cases and in our review of the literature. These data provide a better understanding of the spectrum of genitourinary manifestations in the Klippel-Trénaunay syndrome and provide insight for the clinician to formulate individual therapies for these patients.

Abstract
BACKGROUND The aim of this study was to investigate the diagnostic utility of clinical probability, rapid plasma D-dimer assay, compression ultrasonography (CUS) and transthoracic echocardiography (TTE) in patients with suspected pulmonary embolism. METHODS One hundred forty consecutive outpatients with suspected pulmonary embolism were enrolled in a prospective trial. We evaluated sensitivity, specificity, positive and negative predictive value of a combination of clinical probability, D-dimer, CUS and TTE using perfusion lung scan and pulmonary angiography as a combined gold standard for determining the presence or absence of pulmonary embolism. Clinical probability was assessed in accordance with the PIOPED criteria. The D-dimer (Nycocard) level was considered as abnormal > 0.3 mg/l, the CUS if incompressibility of the leg veins was showed, and the TTE if right ventricular dilation was present, in the absence of chronic pulmonary disease. The combination of these tests was considered consistent with the presence of pulmonary embolism if D-dimer plus CUS and/or TTE showed abnormal results. A pulmonary embolism was excluded if D-dimer and CUS showed normal findings or a low clinical probability was associated with normal findings of CUS and TTE. RESULTS One hundred eleven patients were evaluated. Pulmonary embolism was present in 45/111 (40%) patients. The combination of tests showed positive findings in 39/39 patients with pulmonary embolism, negative findings in 47/50 without pulmonary embolism and non-diagnostic results in 22/111 (20%) patients (95% confidence interval--CI 12-28%). There were three false positive and no false negative results. Sensitivity and specificity were 100 and 94% respectively (95% CI 92-100% and 87-100%); positive and negative predictive values were 93 and 100% (95% CI 85-100% and 93-100%). None of these tests, separately, showed enough sensitivity and specificity. CONCLUSIONS The combination of clinical probability, D-dimer, CUS and TTE was highly accurate to confirm or rule out pulmonary embolism.

Abstract
BACKGROUND AND STUDY OBJECTIVE Echocardiographic detection of right heart thromboemboli (RHTE) during pulmonary embolism (PE) shows an uncommon but life-threatening event. The treatment of this condition is not well established. The aim of our study is to evaluate the efficacy and safety of recombinant tissue-type plasminogen activator (rt-PA) in treating RHTE. METHOD We performed a transthoracic echocardiogram within (mean +/- SD) 120+/-45 min from onset of symptoms on 30 consecutive patients with proven massive PE. Seven patients (23%) showed RHTE, four patients (57%) had cardiogenic shock; and all patients showed echocardiographic features of acute cor pulmonale. The seven patients with RHTE received an IV infusion of 100 mg rt-PA over a period of 2 h with continuous echocardiographic monitoring. RESULTS We observed complete RHTE lysis at 45 to 60 min from the onset of rt-PA infusion and significant reductions at 2 h in the following: 14% in right ventricle (RV) end-diastolic diameter (reduction, 40.8 to 35 mm; p < 0.01); 12% in RV/left ventricular ratio (reduction, 0.83 to 0.73; p < 0.01); and 17% in tricuspid regurgitant flow velocity (reduction, 3.5 to 2.9 m/s; p < 0.01). The interventricular septal and RV wall motions improved. An excellent clinical outcome was achieved rapidly in all patients. No adverse events were recorded. CONCLUSIONS We demonstrated the rapid, effective, and safe action of rt-PA in RHTE resolution and an improvement in pulmonary perfusion. Our data confirm the important role of an early, systematic echocardiographic approach in order to detect RHTE quickly in patients with suspected massive PE.

Abstract
BACKGROUND The purpose of this study was to analyse the attitudes towards and knowledge of primary prevention of venous thromboembolism (VTE) among hospital doctors in Calabria. METHODS The survey was based on theoretical knowledge and practical management of hortopedics, surgeons, gynecologists and internists working in 14 hospitals. RESULTS Out of a total of 340 physicians contacted, 154 (45%) agreed to take part in the survey. 82% of those who responded used VTE prophylaxis on a routine basis. Unfractioned heparin (71%) was the most frequently used methods; early deambulation (55%), low molecular weight heparin (49%) and elastic stocking (49%) were less frequently employed. Surprisingly, one third used aspirin. 75% of those contacted had modified their approach to prevention during the last few years, in particular owing to improvements in pharmacological therapy and increased awareness of the problem. In the survey of clinical practice, 80% of those who took part correctly identified the VTE risk, 86% suggested the best treatment, but only 27% assessed the exact frequency rate of deep venous thrombosis (DVT) and pulmonary embolism (PE) in the absence of prophylaxis. CONCLUSIONS Most of the doctors contacted showed scant interest in the primary prevention of VTE. The 45% who agreed to be interviewed revealed a good practical approach but were not sufficiently aware of the real incidence of DVT and PE in a clinical risk context without prophylaxis. Although they must be interpreted with caution, these findings allow the real behaviour of hospital physicians in this region to be assessed with regard to the primary prevention of VTE and suggest the need for more correct information about this aspect of venous thromboembolic disease which is not yet sufficiently well known.

Abstract
Prosthetic valve thrombosis can determine different degrees of valvular insufficiency or obstruction, with a potentially fatal course. The current literature has not established whether the best treatment is thrombolysis or surgery (thrombectomy or valvular replacement). However, both treatments expose the patient to the risk of serious sequelae or death. Here we describe a case of acute thrombosis in a prosthetic mitral valve. At presentation, the patient was in pulmonary edema and had a low cardiac output. She was treated with recombinant tissue-type plasminogen activator infusion (rt-PA 100 mg in 2 hours). Both clinically as well as echocardiographically, we observed a quick regression of the obstruction, but after the treatment, the patient developed an ischemic stroke with aphasia and hemiplegia. The authors conclude that thrombolysis is a highly effective treatment in resolving prosthetic thrombosis. However, because it carries a significant risk of embolization, it should be limited to patients with hemodynamic deterioration in whom surgery could also entail a significant risk of death.

Abstract
PURPOSE Our aim was to assess whether a voiding cystourethrogram after uncomplicated ureteral reimplantation is necessary or cost-efficient. MATERIALS AND METHODS We retrospectively reviewed the records of patients who underwent uncomplicated reimplantation at our institution from 1988 to 1994. We also reviewed the literature to tabulate the reflux resolution rate from all published series of more than 100 ureters reimplanted. RESULTS At our institution 119 patients (207 ureters) underwent uncomplicated reimplantation and a postoperative voiding cystourethrogram, which documented a 98.6% initial reflux resolution rate. All persistent postoperative reflux resolved spontaneously without treatment for a final resolution rate of 100%. We reviewed 1,494 abstracts using vesicoureteral reflux as a key word and found 19 series of more than 100 ureters reimplanted. The combined results of our series and those 19 from the literature revealed 3,346 patients (5,008 ureters reimplanted). The final reflux resolution rate was 98.58%. Series that included and excluded secondary vesicoureteral reflux documented final reflux resolution rates of 98.4 and 99.04%, respectively. Reflux resolved spontaneously in 85% of the ureters in which it was noted on the initial postoperative cystogram. At our institution the cost of a voiding cystourethrogram is $610 and we perform an average of approximately 20 uncomplicated reimplantations per year. In the United States there are approximately 230 pediatric urologists. If each surgeon performed 20 reimplantations per year at the same cost per voiding cystourethrogram, a cost savings of $2.8 million per year would result if the study were not performed after surgery. CONCLUSIONS In the hands of experienced pediatric urologists uncomplicated ureteral reimplantation has a success rate of 99.04%. The yield of postoperative voiding cystourethrography is exceedingly low and a cost savings of $2.8 million per year would result by omitting the postoperative voiding cystourethrogram.

Abstract
BACKGROUND Clinical history of patients with severe chronic aortic regurgitation is characterized by a long period without any symptom, although the left ventricle enlarges progressively. The administration of oral vasodilators could reduce ventricular enlargement or its progression, delaying the development of myocardial dysfunction and/or the need for valvular surgery. OBJECTIVES To verify the efficacy of long-term captopril therapy to reduce left ventricular mass and dimensions in patients with severe chronic aortic regurgitation. METHODS This is a prospective echocardiographic study in which each individual patient is considered his own control case. Eleven asymptomatic patients with severe chronic aortic regurgitation in sinus rhythm, who had an ejection fraction greater than 50% and were not taking cardiovascular drugs, were orally administered captopril at the maximum tolerated dosage (127 +/- 13 mg/day). Follow-up lasted for 24 +/- 3 months. RESULTS Left ventricular telediastolic diameter decreased from 69 +/- 5 to 61 +/- 3 mm (p < 0.01), telesystolic diameter decreased from 48 +/- 5 to 41 +/- 4 mm (p < 0.01); ejection fraction increased from 56 +/- 4 to 61 +/- 3% (p < 0.001); myocardial mass decreased from 208 +/- 32 to 174 +/- 27 g/m2 (p < 0.01), and mean wall stress from 264 +/- 35 to 203 +/- 25 mmHg (p < 0.001). All variations were still significant at 6 months. CONCLUSIONS These results suggest that captopril has a favourable effect on left ventricular mass, dimensions and load conditions, and could favourably influence the natural history of chronic aortic regurgitation. The efficacy of medical treatment can be verified through serial echocardiographic study.

Abstract
Early diagnosis is important for the prognosis of patients affected with pulmonary embolisms. The mortality rate ranges from 30% in untreated cases to 10% in cases getting early treatment. In this context, it is essential to obtain a correct diagnosis in order to start the best treatment for each patient. The aim of our study is to evaluated the contribution of mono- bidimensional echocardiography and color-doppler for the early diagnosis of acute massive pulmonary embolism. We examined 23 patients (14 women with a mean age of 67 +/- 13 years; 9 men with a mean age of 58 +/- 16 years) who were referred to us for observation over a 30-month period. These patients had been admitted to the intensive care unit for suspected acute massive pulmonary embolism and the diagnosis was subsequently confirmed by a pulmonary scintigraphy. None of the 23 patients showed a positive case history of previous heart disease and/or pulmonary disease. The patients were checked using 2D-doppler echocardiography, 120 +/- 45 minutes from the onset of the symptoms. They were then divided into two groups (A and B) based on the presence or absence of thromboembolus in the right cavity of the heart. Seven patients (30%) revealed thromboemboli and were treated effectively with rt-PA (100 mg/2 hours). An increase in the size of the right ventricle with an affected rate RV/LV > 0.6 and the abnormal kinetics of the ventricular septum proved to be the most sensitive parameters for right ventricular overload, as signs of acute massive pulmonary ambolisms were observed in all 23 patients. Tricuspid regurgitation speed (from 2.9 to 3.6 m/sec) and peak systolic pulmonary pressure (67 mmHg) were recorded in all patients. Our observations suggest that the hemodynamic effects of an acute massive pulmonary embolism can be enumerated and monitored by analyzing ventricle size and septum kinetics. To summarize, echocardiography proved to be a simple and realistic test. It enabled correct diagnosis and made it possible not only to start thrombolytic therapy without requiring other exams, but also to monitor and evaluate the effects of this therapy.

Abstract
We describe a case of a large apical left ventricular thrombus evolving towards canalization and showing echocardiographic features mimicking a left ventricular pseudoaneurysm. Only serial echocardiographic studies allowed an appreciation of the changing morphologic features of the apical structure, permitting differential diagnosis between a canalization of an evolving thrombus and a myocardial free-wall rupture with pseudoaneurysm formation.

Abstract
Three years after the repair of a true left ventricular aneurysm, a 62-year-old man was admitted to our department for spontaneous angina pectoris and heart failure. The two-dimensional echocardiogram revealed a uniformly dilated left ventricle with a large apical aneurysm, in which a thin, continuous, band-like echogenic structure, extending from the interventricular septum to the antero-lateral wall could be visualized. That structure was initially interpreted as a left ventricular false tendon. Color Doppler flow imaging, however, showed a continuous, phasic flow crossing the band-like structure. Thus, the diagnosis of a huge apical pseudoaneurysm was made and subsequently confirmed by angiographic findings. In conclusion, left ventricular pseudoaneurysms may present themselves with unusual morphologic features. In patients with equivocal two-dimensional echocardiographic findings, color Doppler flow imaging is helpful in clarifying morphologic ambiguities and in identifying unsuspected flow abnormalities.

Abstract
The Authors describe a case of artery hypertension caused by the secretion from the mediastinal paraganglioma and they emphasize the importance of correct diagnostic approach to patients with hypertension. This particular case is extremely rare, in literature, in fact, there are only 25 known cases of paraganglioma arising from the sympathetic trunk in the posterior mediastinum.

Abstract
The growth hormone and prolactin response to oral bromazepam (3 mg) was assessed in 5 normal men and 5 normal women. A peak growth hormone response of 11.9 +/- 3.7 ng/ml (mean +/- SD), significantly above the baseline (p less than 0.01), was achieved in the men. On the other hand, there was no statistically significant response of growth hormone secretion in the women. No change in prolactin secretion was observed in either sex.
