Project description:IntroductionOur objective was to describe the contemporary outcomes of orbital atherectomy (OA) vs. rotational atherectomy (RA) use for inpatient percutaneous coronary intervention (PCI) in the United States. Data on the use of OA vs. RA in contemporary inpatient PCI are limited.MethodsWe queried the Nationwide Readmission Database (NRD) from January to November for the years 2016-2017 to identify hospitalizations of patients who underwent PCI with atherectomy. We conducted a multivariate regression analysis to identify variables associated with in-hospital mortality.ResultsWe included 77,040 records of patients who underwent inpatient PCI with atherectomy. Of those, 71,610 (93%) had RA, and 5430 (7%) had OA. There was no significant change in the trend of using OA or RA over 2016 and 2017. OA was less utilized in patients presenting with ST-segment elevation myocardial infarction (STEMI) (4.3% vs. 46.8%, p < 0.001). In our cohort, OA was associated with lower in-hospital mortality (3.1% vs. 5%, p < 0.001) and 30-day urgent readmission (< 0.01% vs. 0.2%, p = 0.009), but a higher risk of coronary perforation (1.7% vs. 0.6%, p < 0.001) and cardiac tamponade (1% vs. 0.3%, p < 0.001) and a higher cost of index hospitalization ($28,199 vs. $23,188, p < 0.001) compared with RA.ConclusionRA remains the predominant atherectomy modality for inpatient PCI in the United States (93%). There was no change in the trend of use for either modality over the years 2016 and 2017. OA was noted to have a lower incidence of in-hospital death, but a higher risk of coronary perforation and a higher cost of index hospitalization for the overall unmatched cohorts.

Project description:A 63-year-old man was admitted with a clinical diagnosis of acute coronary syndrome (non-ST-segment elevation), characterized by regional hypokinesia of the left ventricular posterior and lateral walls and by positive cardiac biomarkers. The coronary angiogram showed a 12.5-mm-diameter aneurysm with a mural thrombus and possible distal embolism to the bifurcation of the left circumflex coronary artery and the 2nd marginal branch. The aneurysm was managed percutaneously by implanting 2 mesh-covered stents in accordance with the "simultaneous kissing stent" technique. Follow-up angiography and optical coherence tomography at 5 postprocedural months documented complete sealing of the aneurysm and diffuse in-stent restenosis. No sign of ischemia occurred during the subsequent follow-up.

Project description:AimEvaluate sex differences in procedural net adverse clinical events and long-term outcomes following rotational atherectomy (RA).Methods and resultsFrom August 2010 to 2016, 765 consecutive patients undergoing RA PCI were followed up for a median of 4.7 years. 285 (37%) of subjects were female. Women were older (mean 76 years vs. 72 years; p < .001) and had more urgent procedures (64.6 vs. 47.3%; p < .001). Females received fewer radial procedures (75.1 vs. 85.1%; p < .001) and less intravascular imaging guidance (16.8 vs. 25.0%; p = .008). After propensity score adjustment, the primary endpoint of net adverse cardiac events (net adverse clinical events: all-cause death, myocardial infarction, stroke, target vessel revascularization plus any procedural complication) occurred more often in female patients (15.1 vs. 9.0%; adjusted OR 1.81 95% CI 1.04-3.13; p = .037). This was driven by an increased risk of procedural complications rather than procedural major adverse cardiac events (MACE). Specifically, women were more likely to experience coronary dissection (4.6 vs. 1.3%; p = .008), cardiac tamponade (2.1 vs. 0.4%; p = .046) and significant bleeding (BARC ≥2: 5.3 vs. 2.3). Despite this, overall MACE-free survival was similar between males and females (adjusted HR 1.03; 95% CI 0.80-1.34; p = .81). Procedural complications during RA were associated with almost double the incidence of MACE at long-term follow-up (HR 1.92; 95% CI 1.34-2.77; p < .001).ConclusionWomen may be at greater risk of procedural complications following rotational atherectomy. These include periprocedural bleeding episodes and coronary perforation leading to cardiac tamponade. Despite this, the adjusted overall long-term survival free of major adverse cardiac events was similar between males and females.

Project description:Complications such as slow flow are frequently observed in percutaneous coronary intervention (PCI) with rotational atherectomy (RA). However, it remains unclear whether the high incidence of slow flow results in the high incidence of periprocedural myocardial infarction (PMI), reflecting real myocardial damage. The aim of this study was to compare the incidence of PMI between PCI with versus without RA using propensity score-matching. We included 1350 elective PCI cases, which were divided into the RA group (n = 203) and the non-RA group (n = 1147). After propensity score matching, the matched RA group (n = 190) and the matched non-RA group (n = 190) were generated. The primary interest was to compare the incidence of PMI between the matched RA and non-RA groups. Before propensity score matching, the incidence of slow flow and PMI was greater in the RA group than in the non-RA group. After matching, the incidence of slow flow was still greater in the matched RA group than in the matched non-RA group (16.8% vs. 9.5%, p = 0.048). However, the incidence of PMI was similar between the matched RA and matched non-RA group (7.4% vs. 5.3%, p = 0.528, standardized difference: 0.086). In conclusion, although use of RA was associated with greater risk of slow flow, use of RA was not associated with PMI after a propensity score-matched analysis. The fact that RA did not increase the risk of myocardial damage in complex lesions would have an impact on revascularization strategy for severely calcified coronary lesions.

Project description:BackgroundAlthough several groups reported the risk factors for slow flow during rotational atherectomy (RA), they did not clearly distinguish modifiable factors, such as burr-to-artery ratio from unmodifiable ones, such as lesion length. The aim of this retrospective study was to investigate the modifiable and unmodifiable factors that were associated with slow flow.MethodsWe included 513 lesions treated with RA, which were classified into a slow flow group (n = 97) and a non-slow flow group (n = 416) according to the presence or absence of slow flow just after RA. The multivariate logistic regression analysis was performed to find factors associated with slow flow.ResultsSlow flow was inversely associated with reference diameter [Odds ratio (OR) 0.351, 95% confidence interval (CI) 0.205-0.600, p<0.001], primary RA strategy (OR 0.224, 95% CI 0.097-0.513, p<0.001), short single run (≤15 seconds) (OR 0.458, 95% CI 0.271-0.776, p = 0.004), and systolic blood pressure (BP) ≥ 140 mmHg (OR 0.501, 95% CI 0.297-0.843, p = 0.009). Lesion length (every 5 mm increase: OR 1.193, 95% CI 1.093-1.301, p<0.001), angulation (OR 2.054, 95% CI 1.171-3.601, p = 0.012), halfway RA (OR 2.027, 95% CI 1.130-3.635, p = 0.018), initial burr-to-artery ratio (OR 1.451, 95% CI 1.212-1.737, p<0.001), and use of beta blockers (OR 1.894, 95% CI 1.004-3.573, p = 0.049) were significantly associated with slow flow.ConclusionsSlow flow was positively associated with several unmodifiable factors including lesion length and angulation, and inversely associated with reference diameter. In addition, slow flow was positively associated with several modifiable factors including initial burr-to-artery ratio and use of beta blockers, and inversely associated with primary RA strategy, short single run, and systolic blood pressure just before RA. Application of this information could help to improve RA procedures.

Project description:ObjectiveHeavy calcifications remain formidable challenges to PCI, even for well-experienced operators. However, rotational atherectomy (RA)-induced coronary perforations (CPs) still could not be obviated. This study was to explore incidence and mechanisms of RA-induced CP in real-world practice. Knowing why CPs occur in RA should help operators avert such mishaps.MethodPatients who received coronary RA from April 2010 to December 2019 with keywords related to perforations were retrieved from database. The procedure details, angiography, and clinical information were reviewed in detail.ResultsA total of 479 RAs were performed with 11 perforations in 10 procedures among 9 patients documented. The incidence of RA-induced CP was 2.1%. The RA vessels were distributed in different territories, including first diagonal branch. Most CPs could be treated conservatively, but prolonged profound shock predisposed to poor outcome. CPs caused by rotawire tip occurred in 18.2% of cases, inappropriately sized burrs in 18.2% of cases, and rotawire damage with subsequent transection and perforation in another 18.2% of cases. A total of 5 (45.5%) perforations were caused by unintended and unnoticed bias cutting into noncalcified plaques (4, 36.4%) or through calcified vessel wall (1, 9.1%). The mechanisms for certain CPs were unique and illustrated in diagrams.ConclusionCPs due to RA occur in certain percentage of patients. The mechanisms for CPs are diverse. Wire damage with subsequent transection could occur due to inappropriately repetitive burr stress on the wire body. A significant portion was due to unintended and unnoticed bias cutting into noncalcified plaque or through calcified vessel wall.

Project description:Objectives:To introduce a modified rotational atherectomy (RA) procedure and investigate the early and midterm outcomes of the RA-facilitating diversified percutaneous coronary intervention (PCI) in a large group of aged patients with higher cardiovascular risk. Background:Previous studies about the outcomes of RA were limited with small sample size and low-risk population. Methods:Between January 2013 and November 2015, 1169 consecutive patients treated with modified RA-facilitated PCI were retrospectively enrolled, including de novo calcified lesions and in-stent restenosis. Patients were regularly followed up for at least 1 year. Major adverse cardiac events (MACE) were analyzed for all participants by different strategies. Cox regression analysis was performed to identify risk factors for the events. Results:The median age of patients was 75 years, with 11.7% of patients on maintenance hemodialysis. Most lesions (99.9%) were complex (American Heart Association type B2/C), and 68.3% were treated with RA?+?drug-eluting-stent (DES). Successful angiography was achieved in 97.8% cases, with 1.7% (20/1169) experiencing coronary perforation (including guidewire perforation). The incidence of MACE was 20.5% and 26.8% at 1-year and 2-year follow-up and were mainly driven by target lesion revascularization (TLR) (10.3% and 12.5%, respectively). The strategy of RA?+?DES had the lowest 2-year MACE, compared with the RA?+?drug-coated balloon and RA?+?plain old balloon angioplasty (14.5%, 30.5%, and 26.0%, respectively). Conclusions:The modified RA technique is a safe and effective tool in the contemporary PCI era, even in high-risk patients. The TLR rate was relatively high but acceptable in such complex lesions.

Project description:During removal of an entrapped guidewire, the core wire can fracture, allowing stretching of the spring wire while the distal guidewire is still entrapped. We resolved this issue with rotational atherectomy, allowing cutting of the spring wire at the intended site, regardless of the proximal spring wire fracture. (Level of Difficulty: Advanced.).
