RESUMEN
INTRODUCTION: Transvenous leads have been implicated in tricuspid valve (TV) dysfunction, but limited data are available regarding the effect of extracting leads across the TV on valve regurgitation. The aim of this study is to quantify tricuspid regurgitation (TR) before and after lead extraction and identify predictors of worsening TR. METHODS: We studied 321 patients who had echocardiographic data before and after lead extraction. TR was graded on a scale (0 = none/trivial, 1 = mild, 2 = moderate, 3 = severe). A change of >1 grade following extraction was considered significant. RESULTS: A total of 321 patients underwent extraction of a total of 338 leads across the TV (1.05 ± 0.31 leads across the TV per patient). There was no significant difference on average TR grade pre- and postextraction (1.18 ± 0.91 vs. 1.15 ± 0.87; p = 0.79). TR severity increased after extraction in 84 patients, but was classified as significantly worse (i.e., >1 grade change in severity) in only 8 patients (2.5%). Use of laser lead extraction was associated with a higher rate of worsening TR postextraction (44.0% vs. 31.6%, p = 0.04). CONCLUSION: In our single-center analysis, extraction of leads across the TV did not significantly affect the extent of TR in most patients. Laser lead extraction was associated with a higher rate of worsening TR after extraction.

BACKGROUND: Early guidance recommended a bolus of intravenous heparin at the beginning of leadless pacemaker (LP) implantation procedures. However, due to concern about bleeding complications, more recent practice has tended toward omitting the bolus and only running a continuous heparin infusion through the introducer sheath. The impact of omitting the heparin bolus on procedural outcomes is not clear. METHODS: We reviewed all Medtronic Micra LP implants at our institution from 9/2014 to 9/2022. The decision to bolus with heparin was at operator discretion. RESULTS: Among 621 LP implants, 326 received an intravenous heparin bolus, 243 did not, and 52 patients were excluded because heparin bolus status could not be confirmed. There was a trend toward more frequent omission of the heparin bolus with more recent implants. Median follow-up after LP implant was 14.3 (interquartile range [IQR]: 8.4-27.9) months. There was no difference between heparin bolus and no bolus groups in the number of device deployments/recaptures (1.42 ± 0.81 vs. 1.31 ± 0.66, p = .15). Implant-related adverse events were also similar between heparin bolus and no bolus groups: access-site hematoma requiring intervention (7 vs. 5, p = .99), pseudoaneurysm (1 vs. 1, p = .99), cardiac perforation (1 vs. 1, p = .99), intraprocedural device thrombus formation (2 vs. 4, p = .41), 30-day rehospitalization (21 vs. 15, p = .98), and 30-day all-cause mortality (16 vs. 14, p = .70). There was one additional nonfatal cardiac perforation in a patient who was excluded due to unknown heparin bolus status. Regarding device electrical parameters between heparin bolus and no bolus groups, there were no significant differences at the time of implant: pacing capture threshold 0.5 ± 0.4 vs. 0.5 ± 0.3, p = .10; pacing impedance 739.9 ± 226.4 vs. 719.1 ± 215.4, p = .52; R wave sensing 11.7 ± 5.7 vs. 12.0 ± 5.4, p = .34). Long-term device performance was also similar between groups. CONCLUSION: Omission of the systemic heparin bolus at the time of LP implantation appears safe in appropriately selected patients. Heparin bolus may still be considered in long cases requiring multiple device deployments or in patients at high risk for thrombotic complications.

BACKGROUND: The topical phosphodiesterase 4 inhibitor roflumilast has been studied in several dermatologic conditions. OBJECTIVE: Roflumilast foam 0.3% is being investigated as a topical treatment for seborrheic dermatitis (SD). METHODS: In this phase 3, double-blinded trial, patients with SD were randomly assigned (2:1 ratio) to once-daily roflumilast foam 0.3% or vehicle foam for 8 weeks. The primary efficacy outcome was Investigator Global Assessment (IGA) Success at week 8, defined as IGA of 0 (Clear) or 1 (Almost Clear) plus ≥2-point improvement from baseline. Safety was also assessed. RESULTS: 79.5% of roflumilast-treated and 58.0% of vehicle-treated patients met the primary endpoint (P < .001); statistically significant differences in IGA Success also favored roflumilast at week 2 (roflumilast: 43.0%; vehicle: 25.7%; P < .001) and week 4 (roflumilast: 73.1%; vehicle: 47.1%; P < .001). Roflumilast was well-tolerated with a low rate of treatment-emergent adverse events. LIMITATIONS: Study limitations include the 8-week treatment period for this chronic condition. CONCLUSIONS: Once-daily roflumilast foam was superior to vehicle in leading to IGA of Clear or Almost Clear plus ≥2-point improvement from baseline at 8 weeks in patients with SD. Longer trials are needed to determine durability and safety of roflumilast foam in SD.

Clindamycin is a lincosamide-derivate antibiotic that has been widely used both systemically and topically for approximately 5 decades. The antimicrobial profile of clindamycin primarily covers several gram-positive bacteria and anaerobic bacteria, with multiple clinical applications supported in the literature and with widespread real-world use. Topical clindamycin has been used primarily for the treatment of acne vulgaris, with both monotherapy and combination therapy formulations available commercially. This article reviews the use of clindamycin as a topical agent with emphasis on therapy for acne vulgaris, and addresses modes of action, reported anti-inflammatory properties that may relate to therapeutic outcomes, recommendations to avoid the emergence of antibiotic-resistant bacteria, tolerability and safety considerations, and published data from clinical studies completed over a span of several years. A discussion of a newly FDA-approved triple-combination formulation is also included. J Drugs Dermatol. 2024;23(6):438-445. doi:10.36849/JDD.8318.

BACKGROUND: Clascoterone cream 1% is a topical androgen receptor inhibitor approved to treat acne vulgaris in patients =>12 years of age. This report provides details of patients who developed laboratory signs of hypothalamic-pituitary-adrenal (HPA) axis suppression without clinical signs of adrenal suppression during the clascoterone development program. METHODS: Two open-label, multicenter, Phase 2 trials evaluated HPA axis suppression in patients with moderate-to-severe acne vulgaris. Study 1 (NCT01831960) enrolled cohorts of adults =>18 years of age and adolescents =>12 to <18 years of age. Study 2 (NCT02720627) enrolled adolescents 9 to <12 years of age. Patients applied clascoterone twice daily at maximum-exposure dosages for 14 days. Adrenal suppression was evaluated via cosyntropin stimulation test (CST) at baseline and day 14. Patients with an abnormal CST result (serum cortisol level =<18 µg/dL) had a follow-up CST approximately 4 weeks later. Blood was collected for pharmacokinetic analysis. Other safety assessments included adverse events (AEs), physical examination/vital signs, and electrocardiography. RESULTS: Overall, 5/69 clascoterone-treated patients had an abnormal CST result on day 14, including 1/20 adults, 2/22 patients aged =>12 to <18 years, and 2/27 patients aged 9 to <12 years. All patients had normal cortisol levels at follow-up testing approximately 4 weeks later. No relationship was observed between abnormal CST results and clascoterone plasma concentrations or the amount of study drug applied. No clinically relevant AEs or clinically significant changes in safety measures were observed in patients with adrenal suppression. CONCLUSION: Clascoterone induced laboratory evidence of mild, reversible HPA axis suppression under maximum-use exposure. J Drugs Dermatol. 2024;23(6):433-437. doi:10.36849/JDD.7997.

BACKGROUND: Tildrakizumab is a humanized anti-interleukin-23 p19 monoclonal antibody approved for the treatment of moderate-to-severe plaque psoriasis. This report describes real-world effectiveness and safety of tildrakizumab through 64 weeks of treatment. METHODS: In this Phase 4, multicenter, uncontrolled, open-label trial (NCT03718299), adults with moderate-to-severe plaque psoriasis received tildrakizumab 100 mg at weeks 0 and 4 and every 12 weeks thereafter through week 52. Effectiveness was assessed from body surface area (BSA) affected and static Physician Global Assessment (sPGA) through week 64 and Psoriasis Area and Severity Index (PASI) through week 52. Adverse events are reported. RESULTS: Of 55 patients enrolled, 45 completed the study and 36 received all doses of tildrakizumab. From baseline to week 64, mean +/- standard deviation BSA decreased by 83.1% (from 14.5 +/- 11.5 to 2.1 +/- 3.6) and sPGA by 67.6% (from 3.2 +/- 0.6 to 1.0 +/- 1.0); sPGA x BSA decreased by 89.6% (from 47.0 +/- 41.5 to 4.6 +/- 9.4; all P<0.001). PASI scores decreased compared to baseline at weeks 4, 16, 28, and 52 (P<0.001). For PASI responses at week 52 compared with baseline, 87.0% achieved greater than or equal to 75% improvement, 56.5% achieved greater than or equal to 90% improvement, and 32.6% achieved 100% improvement. Of 85 treatment-emergent adverse events in 34/55 patients, none were considered related to tildrakizumab treatment. CONCLUSIONS: Tildrakizumab treatment was effective in adult patients with moderate-to-severe plaque psoriasis in real-world settings, with no new safety signals.

Oral isotretinoin remains a mainstay of treatment for severe, recalcitrant nodular acne. Novel formulations of isotretinoin have been developed over the past decade, including lidose isotretinoin and micronized isotretinoin. It is important to understand the differences between isotretinoin formulations to help guide clinical decision-making and selection of isotretinoin therapy. This study aims to provide evidence-based consensus statements regarding the use of novel formulations of isotretinoin for the treatment of moderate-to-severe acne. The Expert Consensus Group consisted of dermatologists with expertise in the treatment of acne. Voting members met in person to conduct a modified Delphi process; a maximum of 2 rounds of voting were conducted for each consensus statement. A total of 5 statements were generated regarding the use of novel formulations of isotretinoin, addressing the efficacy, tolerability, and side effects of novel isotretinoin formulations. All 5 statements achieved agreement with high consensus. The Expert Consensus Group agrees that individualized selection of isotretinoin therapy is important to maximize efficacy and minimize side effects. Compared to generic isotretinoin, micronized isotretinoin may require lower doses to achieve sufficient plasma concentrations. With the increased bioavailability of micronized formulation, there is no need to calculate cumulative dose; instead, the general recommendation with micronized isotretinoin is to treat for at least 5 months, or longer if needed to achieve clearance. Micronized isotretinoin can be taken in the fed or fasted state and has an acceptable safety profile. J Drugs Dermatol. 2024;23(6):429-432. doi:10.36849/JDD.7971.

BACKGROUND: The Patient-Reported Outcomes in Actinic Keratosis (PROAK) study evaluated patient- and clinician-reported outcomes (PRO; ClinRO) during 24 weeks of follow-up among adult patients with actinic keratosis (AK) on the face or scalp who were administered tirbanibulin 1% ointment in real-world community practices in the United States. Methods: Quality of life (QoL) was assessed by Skindex-16 at week (W) 8. Additionally, effectiveness (Investigator Global Assessment [IGA]), PRO and ClinRO (Treatment Satisfaction Questionnaire for Medication and Expert Panel Questionnaire), safety, and tolerability were assessed at W8 and W24. RESULTS: The safety population included 300 patients; the full analysis set included 290 patients (278 patients at W24). At W8, a statistically significant difference (P<0.03) was observed for Skindex-16 domains in all assessed subgroups. Clinicians and patients reported high global satisfaction (mean [SD] scores of 74.9 [23.9] and 72.0 [24.6], respectively) at W24. Overall skin appearance improved from baseline to W24 (83.6% clinicians; 78.5% patients). IGA success (IGA score of 0-1) was achieved by 71.9% of patients at W24 with a similar % at W8 (73.8%) suggesting a stable effectiveness over time. About 5% of patients reported at least one adverse event, 4% reported at least one serious adverse event and no patients reported serious adverse drug reactions. At W8, the most frequently reported local skin reactions were mild/moderate erythema (47.6%) and flaking/scaling (49.6%). CONCLUSIONS: Treatment with tirbanibulin demonstrated effectiveness in the management of AK lesions and a favorable safety and tolerability profile. Furthermore, QoL was improved as early as W8, and both patients and clinicians reported high levels of treatment satisfaction, independently of patients' characteristics.

INTRODUCTION: Chronic exposure to ultraviolet light photoages skin. Retinol, a precursor molecule to retinoic acid that causes less irritation, is available as a nonprescription, cosmetic retinoid and improves collagen production, skin elasticity, and signs of photoaging. Advances in formulation science have allowed the production of stabilized bioactive retinol formulations. This integrated analysis aims to build on previous studies and further examine the comprehensive efficacy and tolerability of topical 0.1% stabilized bioactive retinol. METHODS: This analysis included 6 vehicle-controlled studies of 0.1% stabilized bioactive retinol in women with mild-to-moderate signs of photodamage. Across all studies, the same dermatologist investigator assessed overall photodamage; wrinkles on the forehead, cheeks, and undereye area; crow’s feet wrinkles and fine lines; lack of even skin tone; and brown spots at baseline and weeks 4, 8, and 12 on a numerical scale. Tolerability was also assessed. RESULTS: Participants (retinol, N=237; vehicle, N=234) had a mean (SD) age of 47.4 (6.6) years. Retinol induced greater improvements from baseline in all signs of photoaging vs vehicle as early as week 4 and through 12 weeks of application. Few participants experienced irritation; all events were mild to moderate and transient. The most common signs of irritation were erythema (n=2) and skin scaling/peeling (n=5). CONCLUSIONS: This pooled analysis of 6 vehicle-controlled clinical studies provides new evidence for the efficacy of 0.1% stabilized bioactive retinol in improving signs of photoaging without causing major irritation. Topical 0.1% stabilized bioactive retinol was well tolerated with only a few reported cases of skin irritation. J Drugs Dermatol. 2024;23(4): doi:10.36849/JDD.8124.

BACKGROUND: Topical acne trials often are confounded by high vehicle response rates and differing outcome measures, making it difficult to compare treatments. Number needed to treat (NNT) can be a simple, clinically meaningful way to indirectly compare treatment options without head-to-head data. NNT is the number of patients who need to be treated with an intervention to observe one additional patient successfully achieving a desired outcome versus vehicle/placebo. While treatment attributes such as adverse events may not be captured, lower NNT is a good indicator of a more effective treatment. METHODS: Following a search of combination topical treatments for acne vulgaris, all treatments that reported pivotal trial efficacy data consistent with the 2018 FDA definition of success were included in NNT analyses. Results: Of 13 treatments, 7 reported 12-week treatment success rates in 11 phase 3 trials, with similar baseline demographics/disease severity. Treatment success ranged from 26.8% with tretinoin 0.1%/benzoyl peroxide (BPO) 3% cream to 50% with triple-combination clindamycin phosphate 1.2%/adapalene 0.15%/BPO 3.1% gel. NNTs for the triple-combination gel were 4 and 5 (from 2 pivotal trials). Adapalene 0.3%/BPO 2.5% gel had an NNT of 5. Tretinoin/BPO had the largest range between trials, with NNTs of 4 and 9. The other 4 treatments had NNTs ranging from 6 to 8. CONCLUSION: A comparison of combination topical acne treatment trial data, using the same treatment outcome and similar patient populations, resulted in triple-combination clindamycin phosphate/adapalene/BPO gel and adapalene/BPO gel having the most favorable NNTs.J Drugs Dermatol. 2024;23(2):42-49. doi:10.36849/JDD.7927.

Skin cancer is the most common cancer type in the USA, with over five million annually treated cases and one in five Americans predicted to develop the disease by the age of 70. Skin cancer can be classified as melanoma or non-melanoma (NMSC), the latter including basal cell carcinoma (BCC) and cutaneous squamous cell carcinoma (SCC). Development of BCC and SCC is impacted by environmental, behavioral, and genetic risk factors and the incidence is on the rise, with the associated number of deaths surpassing those caused by melanoma, according to recent reports. Substantial morbidity is related to both BCC and SCC, including disfigurement, loss of function, and chronic pain, driving high treatment costs, and representing a heavy financial burden to patients and healthcare systems worldwide. Clinical presentations of BCC and SCC can be diverse, sometimes carrying considerable phenotypic similarities to benign lesions, and underscoring the need for the development of disease-specific biomarkers. Skin biomarker profiling plays an important role in deeper disease understanding, as well as in guiding clinical diagnosis and patient management, prompting the use of both invasive and non-invasive tools to evaluate specific biomarkers. In this work, we review the known and emerging biomarkers of BCC and SCC, with a focus on molecular and histologic biomarkers relevant for aspects of patient management, including prevention/risk assessments, tumor diagnosis, and therapy selection.
RESUMEN
INTRODUCTION: Plaque psoriasis is a chronic condition that may impact patients' work productivity. Tildrakizumab, an interleukin-23 p19 inhibitor, is approved for treatment of moderate-to-severe plaque psoriasis in adults. However, the effect of tildrakizumab treatment on work productivity in patients with psoriasis is not well characterized. METHODS: In this multicenter, open-label, uncontrolled phase 4 study (NCT03718299), patients with moderate-to-severe plaque psoriasis received tildrakizumab 100 mg at week 0, week 4, and every 12 weeks thereafter through week 52. Patients completed the Work Productivity and Activity Impairment Questionnaire: Psoriasis (WPAI:PSO) at baseline and every 12 weeks from week 16 through week 64. The following four domains of the WPAI:PSO were examined: absenteeism (percentage of time missed from work due to psoriasis), presenteeism (percentage reduction of productivity while at work due to psoriasis), total activity impairment (percentage impairment in activities other than work due to psoriasis), and total work productivity impairment (total percentage of work impairment from both absenteeism and presenteeism due to psoriasis). Missing data were not imputed. RESULTS: Of the 55 patients enrolled, 31 patients completed all domains of the WPAI:PSO at week 64. From baseline to week 64, respectively, mean ± standard deviation (SD) scores improved for presenteeism (20.5 ± 21.7 to 2.6 ± 5.8; P < 0.001), total activity impairment (29.5 ± 26.6 to 4.4 ± 9.4; P < 0.001), and total work productivity impairment (20.9 ± 22.2 to 2.6 ± 5.8; P < 0.001). The mean ± SD score for absenteeism decreased from 1.1 ± 5.7 at baseline to 0.0 ± 0.0 at week 64, but this change was not statistically significant. CONCLUSION: Tildrakizumab treatment mitigated work productivity loss due to psoriasis as measured by the presenteeism, total activity impairment, and total work productivity impairment domains of the WPAI:PSO. TRIAL REGISTRATION: ClinicalTrials.gov identifier, NCT03718299.
RESUMEN
BACKGROUND: Tildrakizumab is an anti-interleukin-23 p19 monoclonal antibody approved for the treatment of moderate-to-severe plaque psoriasis. This report describes final primary results of a 64-week real-world study of the effect of tildrakizumab on patients' health-related quality of life (HRQoL). MATERIALS AND METHODS: In this open-label phase 4 study (NCT03718299), patients with moderate-to-severe plaque psoriasis received tildrakizumab 100 mg at week 0, week 4, and every 12 weeks thereafter through week 52. The primary endpoint was improvement from baseline in HRQoL measured by Psychological General Well-Being Index (PGWBI) total score at weeks 28 and 52. Secondary HRQoL endpoints included change from baseline in Dermatology Life Quality Index (DLQI) score through week 64. Missing data were not imputed. RESULTS: Of 55 patients enrolled, 45 were assessed at week 64. Mean ± standard deviation (SD) total PGWBI score improved from 78.1 ± 14.1 at baseline to 85.2 ± 12.0 at week 52 (p < .001). Mean ± SD DLQI score improved from 9.4 ± 5.2 at baseline to 2.0 ± 2.6 (p < .001) at week 64 with 62.2% of patients having a DLQI score of 0 or 1 at week 64. CONCLUSIONS: Tildrakizumab improved long-term HRQoL in patients with psoriasis in a real-world setting.

Objective.Temperature plays a crucial role in influencing the spatiotemporal dynamics of the heart. Electrical instabilities due to specific thermal conditions typically lead to early period-doubling bifurcations and beat-to-beat alternans. These pro-arrhythmic phenomena manifest in voltage and calcium traces, resulting in compromised contractile behaviors. In such intricate scenario, dual optical mapping technique was used to uncover unexplored multi-scale and nonlinear couplings, essential for early detection and understanding of cardiac arrhythmia.Approach.We propose a methodological analysis of synchronized voltage-calcium signals for detecting alternans, restitution curves, and spatiotemporal alternans patterns under different thermal conditions, based on integral features calculation. To validate our approach, we conducted a cross-species investigation involving rabbit and guinea pig epicardial ventricular surfaces and human endocardial tissue under pacing-down protocols.Main results.We show that the proposed integral feature, as the area under the curve, could be an easily applicable indicator that may enhance the predictability of the onset and progression of cardiac alternans. Insights into spatiotemporal correlation analysis of characteristic spatial lengths across different heart species were further provided.Significance.Exploring cross-species thermoelectric features contributes to understanding temperature-dependent proarrhythmic regimes and their implications on coupled spatiotemporal voltage-calcium dynamics. The findings provide preliminary insights and potential strategies for enhancing arrhythmia detection and treatment.

Rosacea, a chronic skin condition affecting millions of people in the USA, leads to significant social and professional stigmatization. Effective management strategies are crucial to alleviate symptoms and improve patients' quality of life. Encapsulated benzoyl peroxide 5% (E-BPO 5%) is a newly FDA-approved topical treatment for rosacea that shows promise in enhancing therapeutic response and minimizing skin irritation. This review aims to assess the role of recently FDA approved E-BPO 5% in the current treatment landscape for rosacea management, as it is not yet included in clinical guidelines that predominantly rely on older approved therapies. The review focuses on randomized controlled trials conducted in English-speaking adults. It evaluates the efficacy, safety, and tolerability of various US Food and Drug Administration (FDA)-approved agents used for rosacea treatment, including E-BPO cream, metronidazole gel, azelaic acid gel and foam, ivermectin cream, minocycline foam, oral doxycycline, brimonidine gel, and oxymetazoline HCl cream. Existing therapies have been effective in reducing papulopustular lesions and erythema associated with rosacea for many years. E-BPO 5% offers a promising addition to the treatment options due to its microencapsulation technology, which prolongs drug delivery time and aims to improve therapeutic response while minimizing skin irritation. Further research is necessary to determine the exact role of E-BPO 5% in the therapeutic landscape for rosacea. However, based on available evidence, E-BPO 5% shows potential as a valuable treatment option for managing inflammatory lesions of rosacea, and it may offer benefits to patients including: rapid onset of action, demonstrated efficacy by Week 2, excellent tolerability, and sustained long-term results for up to 52 weeks of treatment.

Background: Hypovolemic postural orthostatic tachycardia syndrome (POTS) is thought to be caused by dysregulated circulating blood volume. Management is mainly limited to symptom-targeted lifestyle changes. Radiofrequency venous ablation (RFA) represents a minimally invasive method of increasing circulating blood volume. The following case series describes a novel application of RFA to successfully target POTS symptoms in patients demonstrating venous insufficiency. The use of RFA in alleviating POTS symptoms has not previously been reported. Case summary: We describe four patients with either a well-established historical POTS diagnosis or dysautonomia symptoms refractory to both medical management and lifestyle modifications. They all demonstrated venous reflux on lower extremity venous ultrasound testing. Upon vascular surgery referral, all underwent great and small saphenous vein RFA. They each subsequently reported subjective improvement in their dysautonomia symptoms and quality-of-life. Two with symptom recurrence years later were found to have new-onset pelvic venous congestion and are being evaluated for pelvic venous insufficiency interventions. Discussion: Lower extremity venous pooling can exacerbate dysautonomia symptoms in POTS patients. Patients refractory to conventional treatment strategies should undergo venous insufficiency workup, and if positive, should be referred for venous pooling intervention evaluation. The success of RFA at treating refractory POTS symptoms in these four patients with lower extremity venous reflux, including no surgical intervention and no adverse effects, are compelling grounds to further explore this therapy and to quantify and standardize symptom improvement assessment in a larger patient population. Future directions include a demonstration of quality-of-life improvement in randomized clinical trials.
RESUMEN
BACKGROUND: Data on transvenous (TV) lead-associated superior vena cava (SVC) syndrome are limited. The management of this problem might require a multidisciplinary approach, often involving transvenous lead extraction (TLE) followed by angioplasty and stenting. OBJECTIVE: The purpose of this study was to describe the management and outcome of TV lead-associated SVC syndrome. METHODS: We retrospectively identified patients with a diagnosis of SVC syndrome and TV leads at Emory Healthcare between 2015 and 2023. RESULTS: Fifteen patients with lead-related SVC syndrome were identified. The cohort average age was 50 years. Symptoms included swelling of the face, neck, and upper extremities (67%); shortness of breath (53%); and lightheadedness (40%). Patients had an average of 2 ± 0.7 leads crossing the SVC, with a lead dwell time of 9.8 ± 7.5 years. Thirteen patients were managed with TLE, followed by SVC stenting and angioplasty in 10 and angioplasty alone in 2; 1 patient had no intervention after TLE. One patient was managed with anticoagulation, and another had angioplasty and stenting with lead jailing. One patient experienced SVC perforation and cardiac tamponade during SVC stenting, which was managed successfully with a covered stent and pericardiocentesis. Among the 12 patients with TLE and angioplasty ± stenting, 7 underwent reimplantation of a transvenous lead. Two of those patients had symptoms recurrence, and none of the 5 patients without lead reimplantation had recurrence of symptoms. CONCLUSION: Lead-related SVC syndrome management requires a multidisciplinary approach often including TLE followed by angioplasty and stenting. Avoiding TV lead reimplantation might help reduce symptoms recurrence.
RESUMEN
BACKGROUND: Human in vivo data on the chemical stability of different transvenous lead materials, particularly OptimTM leads, are lacking. OBJECTIVES: The purpose of this study was to determine the chemical reactivity of insulation materials by analyzing the molar mass of extracted pacing and defibrillator leads METHODS: We collected extracted leads at Emory University Hospitals and sent the leads with thermoplastic outer insulation material for molar mass analysis, a material characteristic that informs biostability. Leads were separated based on the chemical identity of the outer insulation material, and the molar mass was measured by an independent party. The extent of chemical reaction was compared across leads having different materials: poly(ether)urethane 55D, poly(ether)urethane 80A, and Optim. RESULTS: A total of 70 leads were extracted. The subset of extracted leads having outer insulation materials composed of PEU or Optim were analyzed for molar mass, where implant times ranged from 0.12 to 16.26 years. The rate of chemical degradation was compared by plotting the extent of reaction [Mn(t = 0)/Mn(t)] as a function of implant time. The Optim molar mass decreased to 40% of its initial value at 10 years of implant. No change in the molar mass of the PEU insulations could be resolved over the same 10-year implant time. CONCLUSION: Because the molar mass of a polymer is directly related to its mechanical integrity, the observed decrease in molar mass of Optim likely translates into premature insulation defects and is consistent with the observed increased rate of electrical malfunction/noise in this subset of cardiac leads.
