Bed Rest Reduction Following Cardiac Catheterizations Using Vascular Closure Devices

Tuozzo, Kristin A; Morris, Reena; Moskowitz, Nicole; McCauley, Kathleen; Babaev, Anvar; Attubato, Michael
BACKGROUND:Bed rest duration following deployment of a vascular closure device after transfemoral left-sided cardiac catheterization is not standardized. Despite research supporting reduced bed rest, many hospitals require prolonged bed rest. Delayed ambulation is associated with back pain, urine retention, difficulty eating, and longer stay. OBJECTIVE:To study length of stay, safety, and opportunity cost savings of reduced bed rest at a large urban hospital. METHODS:A single-site 12-week study of 1-hour bed rest after transfemoral cardiac catheterizations using vascular closure devices. Results were compared with historical controls treated similarly. RESULTS:The standard bed rest group included 295 patients (207 male, 88 female; mean [SD] age, 64.4 [8.6] years). The early ambulation group included 260 patients (188 male, 72 female; mean [SD] age, 64 [9.3] years). The groups had no significant difference in age (t634 = 1.18, P = .21) or sex (χ12=0.2, P = .64). Three patients in the standard bed rest group and 1 in the early ambulation group had hematomas (P = .36). The stay for diagnostic cardiac catheterizations was longer in the standard bed rest group (mean [SD], 220.7 [55.2] minutes) than in the early ambulation group (mean [SD], 182.1 [78.5] minutes; t196 = 4.06; P < .001). Stay for percutaneous coronary interventions was longer in the standard bed rest group (mean [SD], 400.2 [50.8] minutes) than in the early ambulation group (mean [SD], 381.6 [54.7] minutes; t262 = 2.86; P = .005). CONCLUSION:Reduced bed rest was safe, shortened stays, and improved efficiency by creating opportunity cost savings.

Three-Year Outcomes After Bifurcation Stenting With Zotarolimus-Eluting Stents: Final Results From the RESOLUTE ONYX Postapproval Study

Price, Matthew J.; Boutis, Loukas; Kirtane, Ajay J.; Chetcuti, Stanley; Poliaciková, Petra; Dens, Joseph; Attubato, Michael; Wang, Yale; Hu, Patrick; Spriggs, Douglas; Krasnow, Joshua; Chatzizisis, Yiannis; Aminian, Adel; Caputo, Ronald; Shah, Alpesh; Dauler, Michelle; Ibrahim, Sherif; Lung, Te Hsin; Mehran, Roxana
Background: Bifurcation represents a challenging lesion subset for percutaneous coronary intervention. Methods: In this prospective study of the Resolute Onyx zotarolimus-eluting stent (ZES), patients with a single bifurcation target lesion who underwent planned treatment using a provisional stenting technique were enrolled at 25 centers in the United States and Europe. The primary end point was target-vessel failure (TVF) at 1 year, and follow-up was performed through 3 years. Results: A total of 205 patients were enrolled. Mean age was 66.6 ± 10.7 years, 21.5% of patients were female, and diabetes mellitus was present in 30.2%. A provisional approach with a single stent was performed in 96.6% of patients. The rate of TVF at 1 year was 7.4%, fulfilling the prespecified performance criterion (upper 1-sided 95% CI of 11.1%, compared with the performance goal of 24.5%). At 3-year follow-up, the rate of TVF was 12.1%, the rate of clinically driven target-lesion revascularization was 6.0%, and there were no episodes of stent thrombosis related to the target lesion. Event rates were consistent among the cohort of patients with angiographic core laboratory-confirmed bifurcation lesions. Conclusions: In this prospective, multicenter study, bifurcation lesion treatment with Resolute Onyx ZES using a planned provisional stent approach was associated with favorable clinical outcomes through 3 years. These results support the longer-term safety and effectiveness of Resolute Onyx ZES to treat bifurcation lesions that are amenable to a planned provisional stenting technique.

Talmor, Nina; Ramachandran, Abhinay; Brosnahan, Shari B; Shah, Binita; Bangalore, Sripal; Razzouk, Louai; Attubato, Michael; Feit, Frederick; Thompson, Craig; Smilowitz, Nathaniel R
BACKGROUND:The initial wave of the coronavirus disease 2019 (COVID-19) pandemic resulted in an influx of patients with acute viral illness and profound changes in healthcare delivery in New York City. The impact of this pandemic on the presentation and invasive management of acute myocardial infarction (MI) is not well described. METHODS:This single-center retrospective study compared patients with MI who underwent invasive coronary angiography at New York University from March-April 2020, during the peak of the first wave of the pandemic, with those presenting in March-April 2019. RESULTS:Only 35 patients with MI underwent angiography during the study period in 2020 vs 109 patients in 2019. No differences in comorbidities or baseline medications were identified. The proportion of patients with ST-segment elevation MI (STEMI) was higher in 2020 than in 2019 (48.6% vs 24.8%, respectively; P=.01). Median peak troponin concentration was higher (14.5 ng/mL vs 2.9 ng/mL; P<.01) and left ventricular ejection fraction was lower (43.34% vs 51.1%; P=.02) during the pandemic. Among patients with non-STEMI, time from symptom onset to presentation was delayed in 2020 compared with 2019 (median, 24 hours vs 10 hours; P=.04). CONCLUSION/CONCLUSIONS:There was a dramatic decrease in the number of patients with MI undergoing coronary angiography during the first wave of the COVID-19 pandemic. Of those who presented, patients tended to seek care later after symptom onset and had excess myocardial injury. These data indicate a need for improved patient education to ensure timely cardiovascular care during public health emergencies.

Reynolds, Harmony R; Maehara, Akiko; Kwong, Raymond Y; Sedlak, Tara; Saw, Jacqueline; Smilowitz, Nathaniel R; Mahmud, Ehtisham; Wei, Janet; Marzo, Kevin; Matsumura, Mitsuaki; Seno, Ayako; Hausvater, Anais; Giesler, Caitlin; Jhalani, Nisha; Toma, Catalin; Har, Bryan; Thomas, Dwithiya; Mehta, Laxmi S; Trost, Jeffrey; Mehta, Puja K; Ahmed, Bina; Bainey, Kevin R; Xia, Yuhe; Shah, Binita; Attubato, Michael; Bangalore, Sripal; Razzouk, Louai; Ali, Ziad A; Bairey-Merz, C Noel; Park, Ki; Hada, Ellen; Zhong, Hua; Hochman, Judith S
Background: Myocardial infarction with non-obstructive coronary arteries (MINOCA) occurs in 6-15% of MI and disproportionately affects women. Scientific statements recommend multi-modality imaging in MINOCA to define the underlying cause. We performed coronary optical coherence tomography (OCT) and cardiac magnetic resonance imaging (CMR) to assess mechanisms of MINOCA. Methods: In this prospective, multicenter, international, observational study, we enrolled women with a clinical diagnosis of MI. If invasive coronary angiography revealed <50% stenosis in all major arteries, multi-vessel OCT was performed, followed by CMR (cine imaging, late gadolinium enhancement, and T2-weighted imaging and/or T1 mapping). Angiography, OCT, and CMR were evaluated at blinded, independent core laboratories. Culprit lesions identified by OCT were classified as definite or possible. The CMR core laboratory identified ischemia-related and non-ischemic myocardial injury. Imaging results were combined to determine the mechanism of MINOCA, when possible. Results: Among 301 women enrolled at 16 sites, 170 were diagnosed with MINOCA, of whom 145 had adequate OCT image quality for analysis; 116 of these underwent CMR. A definite or possible culprit lesion was identified by OCT in 46.2% (67/145) of participants, most commonly plaque rupture, intra-plaque cavity or layered plaque. CMR was abnormal in 74.1% (86/116) of participants. An ischemic pattern of CMR abnormalities (infarction or myocardial edema in a coronary territory) was present in 53.4% of participants undergoing CMR (62/116). A non-ischemic pattern of CMR abnormalities (myocarditis, takotsubo syndrome or non-ischemic cardiomyopathy) was present in 20.7% (24/116). A cause of MINOCA was identified in 84.5% of the women with multi-modality imaging (98/116), higher than with OCT alone (p<0.001) or CMR alone (p=0.001). An ischemic etiology was identified in 63.8% of women with MINOCA (74/116), a non-ischemic etiology was identified in 20.7% (24/116), and no mechanism was identified in 15.5% (18/116). Conclusions: Multi-modality imaging with coronary OCT and CMR identified potential mechanisms in 84.5% of women with a diagnosis of MINOCA, three-quarters of which were ischemic and one-quarter of which were non-ischemic, alternate diagnoses to MI. Identification of the etiology of MINOCA is feasible and has the potential to guide medical therapy for secondary prevention.

Differential radiation exposure to interventional cardiologists in the contemporary era [Meeting Abstract]

Koshy, L M; Iqbal, S; Xia, Y; Serrano, C; Feit, F; Smilowitz, N R; Bangalore, S; Thompson, C A; Razzouk, L; Attubato, M; Shah, B
Background: Exposure to low-dose ionizing radiation is associated with malignancies. Lead garment specifications in the cardiac catheterization laboratory are not currently regulated, potentially resulting in unprotected areas.
Method(s): Interventional cardiology attendings and fellows wore 7 dosimeters, one externally on the thyroid shield and six inside the lead apron: bilateral axilla, chest wall, and pelvis. Radiation protection included a lower table-mounted lead drape, upper ceiling-mounted lead shield, and use of 7.5 frames per second during fluoroscopy. All procedures were performed with operators standing to the right of the patient. The primary endpoint was operator radiation exposure to the left versus right axilla. Radiation exposures in millirem (mrem) per participant over the study period are shown as median [interquartile range] and compared between left- and right-sided measures using paired Wilcoxon tests.
Result(s): Nine participants (66% female) wore dosimeters during 231 cases. Transradial coronary angiography was selected in 81.1% of cases and PCI was performed in 32.1%. A sterile radiation drape placed on the patient abdomen was used in 18.6% of cases. Median dose area product and fluoroscopy time for the participants ranged from 29.0-60.5 Gy cm2 and 6.2-13.5 minutes, respectively. Radiation exposure at the left axilla was higher than the right axilla (5 vs. 0.9 mrem, p=0.018) but did not differ between left or right chest wall and left or right pelvis (Figure).
Conclusion(s): This analysis demonstrates insufficient protection in the left axillary area. The use of additional left axillary protection should be evaluated. (Figure Presented)

Radiation-Induced Left Main Coronary Artery Stenosis in a Patient with Atretic Internal Mammary Arteries [Case Report]

Dogra, Siddhant; Mahajan, Asha M; Jung, Albert; Attubato, Michael; Saric, Muhamed; Shah, Alan
Coronary artery disease (CAD) is a known potential complication of thoracic radiation treatment that typically affects the proximal segments of the coronary arteries, requiring coronary artery bypass grafting (CABG). We present a case of acute coronary syndrome occurring in a 57-year-old man with prior thoracic radiation therapy following resection of a chest wall chondrosarcoma. Coronary angiogram demonstrated significant areas of stenosis in the left main coronary artery (LMCA) and ostial left anterior descending (LAD) coronary artery. The patient was also found to have atretic bilateral internal mammary arteries as a consequence of his radiation therapy, rendering them unsuitable as grafts. Percutaneous coronary intervention (PCI) was thus performed with a successful outcome. To our knowledge, this is the first case of radiation-induced CAD of the LMCA with atretic internal mammary arteries treated successfully with PCI.
