RESUMEN
BACKGROUND: Patients with previous coronary artery bypass surgery (CABG) who require repeat revascularization frequently undergo percutaneous coronary intervention (PCI). We sought to identify factors associated with the decision to intervene on the native vessel versus a bypass graft and investigate their outcomes in a large nationwide prospective registry. METHODS: We identified patients who underwent PCI with a history of prior CABG from the Netherlands Heart Registration between 2017 and 2021 and stratified them by isolated native vessel PCI versus PCI including at least one venous- or arterial graft. The primary endpoint of major adverse cardiac events (MACE) was a composite of all-cause death and target vessel revascularization (TVR) at one-year post PCI. The key secondary endpoint was a composite of all-cause death, myocardial infarction (MI), and TVR at 30 days. RESULTS: Out of 154,146 patients who underwent PCI, 12,822 (8.3%) had a prior CABG. Isolated native vessel PCI was most frequently performed (75.2%), while an acute coronary syndrome (ACS) presentation was most strongly associated with graft interventions. The primary outcome of MACE at one-year post PCI occurred more frequently in interventions including grafts compared with native vessels alone (19.7% vs. 14.3%; adjOR 1.267; 95% CI 1.101-1.457); p < 0.001) driven by TVR. There was however no difference in mortality or the key secondary endpoint between the two groups. CONCLUSION: In this nationwide prospective registry, ACS presentation was strongly associated with bypass graft PCI. At one year after PCI, interventions including bypass grafts had a higher composite of MACE compared with isolated native vessel interventions.

OBJECTIVES: We sought to evaluate the severity and patterns of calcifications in the left main coronary artery (LMCA) and proximal segments of left anterior descending coronary artery (LAD) and left circumflex artery (LCX) using optical coherence tomography (OCT) in patients with and without prior coronary artery bypass grafting (CABG). BACKGROUND: CABG may accelerate upstream calcium development. METHODS: OCT images (n = 76) of the LMCA bifurcation from either the LAD or LCX in 76 patients with at least one patent left coronary graft, on average 7.0 ± 5.6 years post-CABG, were compared with 148 OCT images in propensity-score-matched non-CABG controls. RESULTS: Minimum lumen areas in the LMCA, LAD, and LCX in post-CABG patients were smaller than non-CABG controls. Maximum calcium arc and thickness as well as calcium length were greater in the LMCA and LCX, but not in the LAD in post-CABG patients versus non-CABG controls. Calcium located at the carina of a bifurcation, calcified nodules (CN), thin intimal calcium, and lobulated calcium were more prevalent in post-CABG patients. After adjusting for multiple covariates, prior CABG was an independent predictor of calcification at the carina of a bifurcation (odds ratio [OR] 5.77 [95% confidence interval, CI: 1.5-21.6]), thin intimal calcium (4.7 [1.5-14.4]), and the presence of a CN (15.60 [3.2-76.2]). CONCLUSIONS: Prior CABG is associated with greater amount of calcium in the LMCA and the proximal LCX, as well as higher prevalence of atypical calcium patterns, including CN, thin or lobulated calcium, and calcifications located at the carina of a bifurcation, compared with non-CABG controls.

The number of patients with severe aortic stenosis (AS) and a history of prior cardiac surgery has increased. Prior cardiac surgery increases the risk of adverse outcomes in patients undergoing aortic valve replacement. To evaluate the impact of prior cardiac surgery on clinical endpoints in patients undergoing transcatheter aortic valve replacement (TAVR) versus surgical aortic valve replacement (SAVR), we performed a literature search using PubMed, Embase, Google Scholar, and Scopus databases. The clinical endpoints included in our study were 30-day mortality, 1-2-year mortality, acute kidney injury (AKI), bleeding, stroke, procedural time, and duration of hospital stay. Seven studies, which included a total of 8221 patients, were selected. Our study found that TAVR was associated with a lower incidence of stroke and bleeding complications. There was no significant difference in terms of AKI, 30-day all-cause mortality, and 1-2-year all-cause mortality between the two groups. The average procedure time and duration of hospital stay were 170 min less (p ≤ 0.01) and 3.6 days shorter (p < 0.01) in patients with TAVR, respectively. In patients with prior coronary artery bypass graft and severe AS, both TAVR and SAVR are reasonable options. However, TAVR may be associated with a lower incidence of complications like stroke and perioperative bleeding, in addition to a shorter length of stay.
RESUMEN
The relationship between periprocedural complications and the type of vascular access in patients with prior history of coronary artery bypass grafting (CABG) and treated with percutaneous coronary interventions (PCIs) is less investigated than in the overall group of patients treated with PCI. The aim of the current study was to assess the relationship between the type of vascular access and selected periprocedural complications in a group of patients with prior history of CABG and treated with PCIs. Based on a Polish nationwide registry of interventional cardiology procedures called ORPKI, the authors analyzed 536,826 patients treated with PCI between 2014 and 2018. The authors extracted 32,225 cases with prior history of CABG. Then, patients with femoral and radial access as well as right and left radial access were compared. This comparison was proceeded by propensity score matching (PSM). After PSM, a multifactorial analysis revealed that patients treated with PCI from femoral access were significantly more often related to periprocedural deaths (odds ratio [OR]: 1.79; 95%, confidence interval [CI]: 1.1-3.0, p = 0.02) and cardiac arrests (OR: 1.98; 95%, CI: 1.38-2.87, p < 0.001). After inclusion of the Killip class grade and the occurrence of cardiac arrests before PCI into the PSM, the significance remained for procedural related cardiac arrests (OR: 1.55; 95%, CI: 1.07-2.28, p = 0.022]). However, a comparison of right and left radial access showed no significant differences between procedure-related complications. It has been confirmed that there is a statistical association between femoral access (compared to radial access) and a higher rate of periprocedural cardiac arrests in patients with prior history of CABG treated with PCI.
RESUMEN
BACKGROUND: The incidence of patients with previous history of coronary artery bypass grafting (CABG) presenting for aortic valvular replacement has been consistently on the rise. Repeat sternotomy for surgical aortic valve replacement (SAVR) carries an inherent risk of morbidity and mortality when compared to Transcatheter aortic valve replacement (TAVR). METHODS: The Nationwide inpatient sample (NIS) from 2012 to 2014 was queried using the International Classification of Diseases-Ninth edition, Clinical Modification (ICD-9-CM) codes to identify all patients ≥ 18 years with prior CABG who underwent TAVR (35.05 and 35.06) or SAVR (35.21 and 35.22). Propensity score matching (1:1) was performed and in-hospital outcomes were compared between matched cohorts. RESULTS: From 2012 to 2014, there was progressive increase in the annual number of TAVR procedures from 1485 to 4020, with a decrease in patients undergoing SAVR from 2330 to 1955 (Ptrend < 0.0001) in the above population. There was no significant difference in in-hospital mortality rates. Compared to SAVR, TAVR was associated with lower risk of stroke (1.2% vs. 3.3%, P = 0.009), AKI (12.9% vs. 21.3%, P < 0.0001), myocardial infarction (0.9% vs. 2.7%, P = 0.01) and major bleeding (9.1% vs. 25.1%, P < 0.0001). TAVR was associated with higher risk of pacemaker implants (9.6% vs. 4.9%, P = 0.001) and trend toward lower risk of vascular complications (2.3% vs. 4.1%, P = 0.05). CONCLUSION: In this large cohort of patients with previous CABG, there is no significant difference in in-hospital mortality between TAVR and SAVR. TAVR was associated with lower risk of in-hospital outcomes.

AIMS: Patients undergoing percutaneous coronary intervention (PCI), with a history of coronary artery bypass grafting (CABG), may be at increased risk for mortality and repeat revascularization, compared with patients without prior CABG. In this post-hoc analysis of the ORBIT II trial, safety and efficacy of coronary orbital atherectomy (OA) to modify severe coronary artery calcium, prior to stent placement, was evaluated in subjects based on history of CABG. METHODS AND RESULTS: Comorbidities: diabetes, dyslipidemia, hypertension, and history of myocardial infarction (MI) were more prevalent in the CABG group. The in-hospital major adverse cardiac event (MACE) rate, defined as a composite of cardiac death, MI (CK-MB>3× ULN), and target vessel revascularization (TVR), was higher in the CABG group (16.9% vs. 8.5%, p=0.04), driven primarily by a higher incidence of MI (16.9% vs. 8.0%, p=0.03); however, Q-wave rates were low at 1.5% vs 0.5%, (p=0.38). There was no significant difference in rates of cardiac death (6.2% vs. 2.7%, p=0.17) and TVR (7.9% vs. 5.5%, p=0.47). CONCLUSIONS: Low rates of TVR, cardiac death, and Q-wave MI, suggest OA treatment to facilitate stent delivery is successful and provides durable outcomes in subjects with and without prior CABG. CONDENSED ABSTRACT: Patients with history of CABG have extensive coronary artery disease. Those who undergo PCI may be at increased risk for mortality and repeat revascularization, compared with patients without prior CABG. This post-hoc analysis of ORBIT II trial evaluated safety and efficacy of coronary OA to modify severe coronary artery calcium, prior to stent placement, based on subject history of CABG. The MACE rate was higher in the CABG group, driven by higher incidence of MI; however, Q-wave rates were low. OA treatment to facilitate stent delivery is successful, but higher incidence of non-Q-wave MI in CABG patients warrants further study.
