RESUMO

Double kissing crush (DK crush) is one of the preferred strategies for bifurcation stenting due to the lower risk of target vessel failure but can be difficult to perform. Difficulty in wiring the jailed side branch after stenting the main vessel is not uncommon. The retrograde crossing can provide a solution in selected cases when antegrade rewiring of a jailed side branch fails during DK crush (or other bifurcation stenting techniques).

RESUMO

OBJECTIVES: The aim of this study was to describe management of recurrent pulmonary vein stenosis (PVS) and determine if stenting is superior to balloon angioplasty (BA) in preventing subsequent restenosis. BACKGROUND: PVS is a serious complication of atrial fibrillation ablation. BA and stenting are effective therapies; however, restenosis frequently occurs. Here we report management of recurrent stenosis. METHODS: This was a prospective observational study performed from 2000 to 2014. RESULTS: One hundred and thirteen patients with severe PVS underwent intervention in 88 veins treated with BA and 81 treated with stenting. Forty-two patients experienced restenosis. Restenosis was more common in veins treated with BA (RRR 53% [95% CI 32-70%, p = .008]). A second intervention was performed in 41 patients. In the 34 vessels treated with initial BA, 24 were treated for restenosis with a stent and 10 were treated with a second BA. The recurrence rate was 46% in those treated with BA followed by stenting and 50% in those treated with two BA procedures. In the 22 veins treated with initial stenting, 9 were treated with another stent and 13 were treated with BA. The recurrence rate was 44% in those treated with a second stent and 46% for those treated with a stent followed by BA. The risk of a third stenosis was the same among all groups (Analysis of variance [ANOVA] p = .99). Limited sample size precluded analysis of outcome by stent size. CONCLUSIONS: Restenosis occurred in 44% of patients overall. Management is challenging; stenting does not appear to be superior to BA.

RESUMO

BACKGROUND: Transcatheter edge-to-edge repair with MitraClip is only approved for treatment of mitral regurgitation but is increasingly used to treat concomitant tricuspid regurgitation (TR) due to its common coexistence and association with poor outcomes. This study aimed to describe the learning curve associated with the challenge of off-label treatment of concomitant TR. METHODS: This is a retrospective review of initial and consecutive patients who underwent combined edge-to-edge repair of mitral and tricuspid valves (TVs) at our institution from August 2017 to October 2019. RESULTS: Repair of both valves with MitraClip was performed in 22 patients (median age 81.5 years, 32% female). Mean procedure time was 176 ± 47 min; mean fluoroscopy time was 65 ± 24 min. Procedure duration in the first tertile was significantly longer (223 ± 13 min) than in the third tertile (143 ± 23 min, p = .0003). Median number of total clips placed per case was 3; in 15 patients (68%), the anterior and septal leaflets of the TV were clipped. The average changes in mean right atrial (RA) and left atrial (LA) pressures were -1.7 ± 2.5 mmHg (p = .0080) and -3.2 ± 4.6 mmHg (p = .0045), respectively. The average changes in RA and LA V-wave heights were -3.3 ± 4.0 mmHg (p = .0009) and -8.1 ± 9.9 mmHg (p = .038), respectively. There was a significant trend toward decreasing residual TR over the course of the series (p = .046). At 30 days, survival was 100% and mean NYHA class decreased from 2.8 to 1.8 (p < .0001). CONCLUSIONS: Combined edge-to-edge tricuspid and mitral valve repair is safe and feasible. With experience, procedure duration and residual TR decreased.

RESUMO

OBJECTIVES: We described hepatitis C virus antibody (anti-HCV) prevalence in a state prison system and retrospectively evaluated the case-finding performance of targeted testing of the 1945 to 1965 birth cohort in this population. METHODS: We used observational data from universal testing of Pennsylvania state prison entrants (June 2004-December 2012) to determine anti-HCV prevalence by birth cohort. We compared anti-HCV prevalence and the burden of anti-HCV in the 1945 to 1965 birth cohort with that in all other birth years. RESULTS: Anti-HCV prevalence among 101,727 adults entering prison was 18.1%. Prevalence was highest among those born from 1945 to 1965, but most anti-HCV cases were in people born after 1965. Targeted testing of the 1945 to 1965 birth cohort would have identified a decreasing proportion of cases with time. CONCLUSIONS: HCV is endemic in correctional populations. Targeted testing of the 1945 to 1965 birth cohort would produce a high yield of positive test results but would identify only a minority of cases. We recommend universal anti-HCV screening in correctional settings to allow for maximum case identification, secondary prevention, and treatment of affected prisoners.

RESUMO

Antiplatelet therapy is integral to reduce the risk of future ischemic events following acute coronary syndrome (ACS) or percutaneous coronary intervention (PCI); this aim must be balanced by limiting the risk of bleeding. Women with ACS or undergoing PCI have distinct platelet physiology, vascular anatomy, and clinical profiles that can influence the selection of an appropriate regimen. There are procedural techniques that can enhance safety in women. The poor inclusion of women in ACS and PCI trials limits our understanding of the ideal antiplatelet regimen in women, and future studies must find ways to increase the participation of female patients.

RESUMO

Takayasu arteritis is characterized by blood vessel inflammation involving the aorta and its branches. We describe a patient with Takayasu arteritis with severe multivessel involvement and classic physical examination findings but virtually no symptoms because of the presence of extensive collateral circulation seen on computed tomography angiography and magnetic resonance angiography imaging.

RESUMO

Pericardial effusions are rarely brought to clinical attention in pregnancy. When present, effusions are typically small, clinically silent, and related to fluid shifts in pregnancy. We present a case of a large pericardial effusion during the third trimester of pregnancy with management considerations for labor and delivery.

RESUMO

Cardiovascular disease is the leading cause of death in women. It remains underdiagnosed, undertreated, and portends worse outcomes in women than men. Disparities exist in every stage of science, from bench research to the editorial board of major journals and in every cardiovascular subspecialty. This review summarizes differences in cardiovascular risk factors and disparities in management and outcomes of ischemic heart disease, heart failure, aortic stenosis, and atrial fibrillation. It also provides an overview of female representation as participants and leaders of clinical trials, editorial boards, and academic institutions. Strategies to overcome these disparities are proposed with examples of successful programs.

RESUMO

BACKGROUND: Stress echocardiographic (SE) testing is an important modality in cardiovascular risk stratification and obstructive coronary artery disease assessment. Binary sex-based parameters are classically used for the interpretation of these studies, even among transgender women (TGW). Coronary artery disease is a leading cause of morbidity and mortality in this population. Yet, it remains unclear whether TGW exhibit a distinct stress testing profile from their cisgender counterparts. METHODS: Using a matched case-control study design, the authors compared the echocardiographic stress testing profiles of TGW (n = 43) with those of matched cisgender men (CGM; n = 84) and cisgender women (CGW; n = 86) at a single center. Relevant data, including demographics, comorbidities, and cardiac testing data, were manually extracted from the patients' charts. RESULTS: The prevalence of hypertension and dyslipidemia was similar between TGW and CGW and lower than that of CGM (P = .003 and P = .009, respectively). The majority of comorbidities and laboratory values were similar. On average, TGW had higher heart rates than CGM (P = .002) and had lower blood pressures than CGM and CGW (P < .05). TGW's double product and metabolic equivalents were similar to those among CGW and lower than those of CGM (P = .016 and P = .018, respectively). On echocardiography, left ventricular end-diastolic and end-systolic diameters among TGW were similar to those of CGW but lower than those of CGM (P = .023 and P = .018, respectively). Measures of systolic and diastolic function, except for exercise mitral valve E/e' ratio, which was lower in TGW than CGW (P = .029), were largely similar among the three groups. There was no difference in the wall motion score index, and therefore, no difference in the percentage of positive SE test results. CONCLUSIONS: This study shows, for the first time, that TGW have a SE profile that is distinct from that of their cisgender counterparts. Larger, multicenter, prospective studies are warranted to further characterize the SE profile of TGW.

RESUMO

This prospective ex vivo and in vitro pharmacodynamic (PD)/pharmacokinetic investigation was conducted in patients with diabetes mellitus with (n = 31) and without chronic kidney disease (n = 30). PD assessments included platelet reactivity index, maximum platelet aggregation, and P2Y12 reaction units. Ex vivo pharmacokinetic assessments included plasma levels of clopidogrel and its active metabolite. In vitro PD assessments were conducted on baseline samples incubated with escalating concentrations of clopidogrel and its active metabolite. Among patients with diabetes mellitus treated with clopidogrel, impaired renal function was associated with increased maximum platelet aggregation. This finding could be attributed partially to upregulation of the P2Y12 activity without differences in drug absorption or metabolism.

RESUMO

BACKGROUND: Among patients treated with a novel oral anticoagulant (NOAC) undergoing percutaneous coronary intervention (PCI), combination therapy with clopidogrel (ie, known as dual antithrombotic therapy [DAT]) is the treatment of choice. However, there are concerns for individuals with impaired response to clopidogrel. OBJECTIVES: The authors sought to assess the pharmacodynamic (PD) effects of clopidogrel vs low-dose ticagrelor in patients with impaired clopidogrel response assessed by the ABCD-GENE score. METHODS: This was a prospective, randomized PD study of NOAC-treated patients undergoing PCI. Patients with an ABCD-GENE score ≥10 (n = 39), defined as having impaired clopidogrel response, were randomized to low-dose ticagrelor (n = 20; 60 mg twice a day) or clopidogrel (n = 19; 75 mg once a day). Patients with an ABCD-GENE score <10 (n = 42) were treated with clopidogrel (75 mg once a day; control cohort). PD assessments at baseline and 30 days post-randomization (trough and peak) were performed to assess P2Y12 signaling (VerifyNow P2Y12 reaction units [PRU], light transmittance aggregometry, and vasodilator-stimulated phosphoprotein); makers of thrombosis not specific to P2Y12 signaling were also assessed. The primary endpoint was PRU (trough levels) at 30 days. RESULTS: At 30 days, PRU levels were reduced with ticagrelor-based DAT compared with clopidogrel-based DAT at trough (23.0 [Q1-Q3: 3.0-46.0] vs 154.5 [Q1-Q3: 77.5-183.0]; P < 0.001) and peak (6.0 [Q1-Q3: 4.0-14.0] vs 129.0 [Q1-Q3: 66.0-171.0]; P < 0.001). Trough PRU levels in the control arm (104.0 [Q1-Q3: 35.0-167.0]) were higher than ticagrelor-based DAT (P = 0.005) and numerically lower than clopidogrel-based DAT (P = 0.234). Results were consistent by light transmittance aggregometry and vasodilator-stimulated phosphoprotein. Markers measuring other pathways leading to thrombus formation were largely unaffected. CONCLUSIONS: In NOAC-treated patients undergoing PCI with an ABCD-GENE score ≥10, ticagrelor-based DAT using a 60-mg, twice-a-day regimen reduced platelet P2Y12 reactivity compared with clopidogrel-based DAT.

RESUMO

Percutaneous coronary intervention of heavily calcified coronary vessels can be challenging due to difficult equipment delivery and suboptimal stent expansion, leading to worse clinical outcomes. Supportive guidewires are designed to facilitate equipment delivery. We present two cases of heavily calcified and tortuous coronary lesions in which use of support guidewires hindered balloon and stent delivery, possibly by increasing friction between equipment and the wall of the coronary vessel. Equipment delivery was achieved using less supportive workhorse guidewires.

RESUMO

Despite significant progress, chronic total occlusion (CTO) percutaneous coronary interventions (PCI) are often challenging and carry increased risk of complications. We present a highly complex CTO PCI case that was successfully completed despite numerous complications (perforation, donor vessel closure, stent loss, guide extension tip fracture, access site bleeding and cardiac arrest) to highlight the importance of appropriate patient selection, pre-procedural planning, comprehensive patient-centered risk/benefit discussion, and prompt recognition and treatment of intra-procedural complications.

RESUMO

BACKGROUND: A drug-drug interaction (DDI) may occur when transitioning from intravenous P2Y12 inhibition with cangrelor to oral P2Y12 inhibition with prasugrel. However, this has never been tested in patients undergoing percutaneous coronary intervention (PCI). OBJECTIVES: This study sought to rule out a DDI when cangrelor and prasugrel are concomitantly administered in PCI patients. METHODS: SWAP-6 (Switching Antiplatelet-6) was a prospective, randomized, 3-arm, open-label pharmacokinetic (PK) and pharmacodynamic (PD) study. Patients (N = 77) were randomized to 1) prasugrel only at the start of PCI, 2) cangrelor plus prasugrel concomitantly at the start of PCI, or 3) cangrelor at the start of PCI plus prasugrel at the end of infusion. Cangrelor infusion was maintained for 2 hours. PK/PD assessments were performed at baseline and 6 time points postrandomization. The primary endpoint was noninferiority in VerifyNow (Werfen) P2Y12 reaction units measured at 4 hours after randomization between cangrelor plus prasugrel concomitantly administered vs prasugrel only. PK assessments included plasma levels of the active metabolite of prasugrel. RESULTS: Compared with prasugrel, cangrelor further enhances P2Y12 inhibitory effects. At 4 hours postrandomization, P2Y12 reaction unit levels were significantly lower with prasugrel only compared to cangrelor and prasugrel concomitantly administered (least squares means difference = 130; 95% CI: 85-176), failing to meet the prespecified noninferiority margin. Findings were corroborated by multiple PD assays. The active metabolite of prasugrel levels were not affected by concomitant administration of cangrelor and were low at the end of cangrelor infusion. CONCLUSIONS: In patients undergoing PCI, concomitant administration of prasugrel with cangrelor leads to a marked increase in platelet reactivity after stopping cangrelor infusion, supporting the presence of a DDI.

RESUMO

BACKGROUND: The COVID-19 pandemic and iodinated contrast shortage may have affected interventional cardiology (IC) fellowship training. OBJECTIVES: The aim of this study was to investigate the educational experience of first-year IC fellows in the United States and Canada. METHODS: A 59-question online survey was conducted among 2021-2022 first-year IC fellows in the United States and Canada. RESULTS: Of the 360 IC fellows invited to participate, 111 (31%) responded; 95% were from the United States, and 79% were men. Participants were mostly from university programs (70%), spent 61 to 70 hours/week in the hospital, and had an annual percutaneous coronary intervention case number of <200 (5%), 200 to 249 (8%), 250 to 349 (33%), 350 to 499 (39%), 500 to 699 (12%), or ≥700 (3%). For femoral access, a micropuncture needle was used regularly by 89% and ultrasound-guided puncture by 81%, and 43% used vascular closure devices in most cases (>80%). Intravascular ultrasound was performed and interpreted very comfortably by 62% and optical coherence tomography (OCT) by 32%, and 20% did not have access to OCT. Approximately one-third felt very comfortable performing various atherectomy techniques. Covered stents, fat embolization, and coil embolization were used very comfortably by 14%, 4%, and 3%, respectively. Embolic protection devices were used very comfortably by 11% to 24% of IC fellows. Almost one-quarter of fellows (24%) were warned about their high radiation exposure. Eighty-four percent considered IC fellowship somewhat or very stressful, and 16% reported inadequate psychological support. CONCLUSIONS: This survey highlights opportunities for improvement with regard to the use of intravascular imaging, atherectomy techniques, complication prevention and management strategies, radiation awareness and mitigation, and psychological support.

RESUMO

BACKGROUND: Delays in diagnosis of peripartum cardiomyopathy (PPCM) are common and are associated with worse outcomes; however, few studies have addressed methods for improving early detection. HYPOTHESIS: We hypothesized that easily accessible data (heart rate [HR] and electrocardiograms [ECGs]) could identify women with more severe PPCM and at increased risk of adverse outcomes. METHODS: Clinical data, including HR and ECG, from patients diagnosed with PPCM between January 1998 and July 2016 at our institution were collected and analyzed. Linear and logistic regression were used to analyze the relationship between HR at diagnosis and the left ventricular ejection fraction (LVEF) at diagnosis. Outcomes included overall mortality, recovery status, and major adverse cardiac events. RESULTS: Among 82 patients meeting inclusion criteria, the overall mean LVEF at diagnosis was 26 ± 11.1%. Sinus tachycardia (HR > 100) was present in a total of 50 patients (60.9%) at the time of diagnosis. In linear regression, HR significantly predicted lower LVEF (F = 30.00, p < .0001). With age-adjusted logistic regression, elevated HR at diagnosis was associated with a fivefold higher risk of overall mortality when initial HR was >110 beats per minute (adjusted odds ratio 5.35, confidence interval 1.23-23.28), p = .025). CONCLUSION: In this study, sinus tachycardia in women with PPCM was associated with lower LVEF at the time of diagnosis. Tachycardia in the peripartum period should raise concern for cardiomyopathy and may be an early indicator of adverse prognosis.

RESUMO

INTRODUCTION: Cardiovascular disease is the most common cause of morbidity and mortality in the United States. Patients are increasingly using internet search to find health-related information, including searches for cardiovascular diseases and risk factors. We sought to evaluate the change in the state by state correlation of cardiovascular disease and risk factors with Google Trends search volumes. METHODS: Data on cardiovascular disease hospitalizations and risk factor prevalence were obtained from the publically available Centers for Disease Control and Prevention website from 2006 to 2018. Google Trends data were obtained for matching conditions and time periods. Simple linear regression was performed to evaluate for an increase in correlation over time. RESULTS: Hospitalizations for six separate cardiovascular disease conditions showed moderate to strong correlation with online search data in the last period studied (heart failure (0.58, p < .001), atrial fibrillation (0.57, p < .001), coronary heart disease (0.58, p < .001), myocardial infarction (0.70, p < .001), stroke (0.62, p < .001), cardiac dysrhythmia (0.46, p < .001)) in the United States. All diseases studied showed a positive increase in correlation throughout the time period studied (p < .05). All five of the cardiovascular risk factors studied showed strong correlation with online search data; diabetes (R = 0.78, p < .001), cigarette use (R = 0.79, p < .001), hypertension (R = 0.81, p < .001), high cholesterol (R = 0.59, p < .001), and obesity (p = 0.80, p < .001) in the United States. Three of the five risk factors showed an increasing correlation over time. CONCLUSION: The prevalence of and hospitalizations for cardiovascular conditions in the United States strongly correlate with online search volumes in the United States when analyzed by state. This relationship has progressively strengthened or been strong and stable over recent years for these conditions. Google Trends represents an increasingly valuable tool for evaluating the burden of cardiovascular disease and risk factors in the United States.

RESUMO

BACKGROUND: Investigational transcatheter edge-to-edge repair (TEER) for severe tricuspid regurgitation (TR) has shown promise as an alternative to surgery, but factors influencing outcomes, optimal patient selection, and procedural timing remain incompletely defined. Given the limitations of determining TR severity by conventional echocardiography, our objectives were to determine whether invasive right atrial (RA) pressures performed during the procedure are related to patient outcomes. METHODS: This study was a retrospective review of patients who underwent off-label tricuspid TEER using MitraClip (Abbott Vascular, Menlo Park, CA) for significant TR at a single institution. Intraprocedural mean RA pressure, RA peak V-wave, RA pressure nadir, and systolic increase in RA pressure (XV height) were recorded. RESULTS: Thirty-eight patients underwent tricuspid TEER; 33 underwent concomitant mitral TEER for mitral regurgitation. The study cohort was 39% female with a mean age of 78.6±14.3 years. Median follow-up was 339 days (interquartile range, 100-601). Any reduction in mean RA pressure, RA peak V-wave, RA nadir, and XV height occurred in 74%, 82%, 45%, and 87% of patients, respectively. At 1 year, event-free survival was 47%. Postprocedure XV height correlated with TR severity as determined by echocardiography (P<0.0001). The highest quartile of postprocedure XV height (>8 mm Hg) had worse event-free survival compared with those who had concluding XV height ≤8 mm Hg (P=0.02). Attainment of a concluding XV height less than or equal to median value was associated with a lower creatinine the next day (1.27±0.47 versus 1.64±0.47 mg/dL, P=0.04). CONCLUSIONS: Intraprocedural XV height correlates with TR severity after tricuspid TEER, and lower concluding pressures are associated with improved outcomes. Analysis of RA pressures may serve as a complementary tool for the evaluation of disease severity and procedural guidance.

RESUMO

INTRODUCTION: Transgender women have been reported to have a high burden of cardiovascular disease (CVD) and risk factors based largely on surveys. Our aim was to describe the prevalence of CVD and associated comorbidities among a cohort of older transgender women referred to cardiology as part of their gender-affirming care. METHODS: This was a retrospective, cross-sectional study of transgender women at a single institution from 2017 to 2019. RESULTS: Fifty-two consecutive patients were included. The most common reasons for referral were cardiac risk factor management (45%) and pre-operative cardiac risk stratification prior to gender-affirming surgery (35%). The mean age was 57 ± 10 years, 87% were white, and 92% had insurance coverage. Forty-eight patients (92%) were taking gender-affirming hormone therapy; 5 had undergone breast augmentation, 4 had undergone orchiectomy, and 2 had undergone vaginoplasty. The most common comorbidities were depression and/or anxiety (63%), obesity (58%), and hyperlipidemia (54%). Excluding aldosterone antagonists, 46% were on cardiac medications; changes were recommended for 25% of patients: new prescriptions in 9, dose adjustments in 5, and discontinuations in 4. According to the pooled cohort equation, the 10-year risk of atherosclerotic CVD was 9.4 ± 7.7% when the study population was calculated as male and 5.2 ± 5.1% when calculated as female (p <0.001). For patients who completed exercise testing, the functional aerobic capacity was fair (77.6 ± 21.4%) when calculated as male and average (99.5 ± 27.5%) as female (p < .0001); there was inconsistency in sex used for calculating the result on the formal report. CONCLUSIONS: Older transgender women may have an underestimated prevalence of CVD and its risk factors. More research is needed to identify cardiovascular health profiles, improve practice consistency, and establish normative values for transgender patients.

RESUMO

This study sought to examine the differences in the characteristics and outcomes between men and women who underwent percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) for acute myocardial infarction (AMI) in contemporary US practice. The Nationwide Inpatient Sample was used to identify patients who underwent revascularization for AMI between January 1, 2003 and December 31, 2016. The primary outcome was in-hospital mortality. Propensity score matching was utilized to account for differences in baseline characteristics. In total, 3,603,142 patients were included, of whom only 1,180,436 (33%) were women. Compared with men, women were older and had higher prevalence of key co-morbidities including diabetes, hypertension, congestive heart failure, and chronic kidney and lung disease (p <0.001). In the PCI cohort, women were significantly less likely to undergo multivessel PCI, to receive mechanical circulatory support, or to undergo atherectomy. In the CABG group, women were more likely to have concomitant valve surgery. In the propensity-matched cohorts, in-hospital mortality was higher for women than men regardless of revascularization strategy: 7.6% versus 6.6% for PCI in ST-elevation myocardial infarction, 2.0% versus 1.9% for PCI in non-ST-elevation myocardial infarction, and 5.7% versus 4.3% for CABG in any AMI (p <0.001). Women also had higher rates of major complications, longer hospitalizations, higher costs, and were less likely to be discharged home (vs nursing facility). These sex-based differences persisted over the study 14-year period. In conclusion, in a contemporary nationwide analysis of propensity score-matched patients, women who undergo revascularization for AMI have worse in-hospital outcomes than men regardless of revascularization mode.
