Project description:BackgroundThe incidence of severe complications such as burr entrapment or perforation is considerable with rotational atherectomy (RA). Halfway RA is a novel strategy, in which an operator does not advance the burr to the end of a continuous calcified lesion, and performs balloon dilatation to treat the remaining part of the calcified lesion. The purpose of this study was to compare complications after halfway and conventional RA.MethodsWe included 307 consecutive lesions that were divided into a conventional RA group (n = 244) and halfway RA group (n = 63). In analysis 1, the incidence of complications was compared between the conventional RA and halfway RA groups. Propensity-score matching was used to match the intentional halfway RA and conventional RA. In analysis 2, the incidence of complications was compared between the matched conventional RA and intentional halfway RA groups.ResultsBurr entrapment (0.4%) and major perforation (0.8%) were observed in the conventional RA group, whereas there was no burr entrapment or perforation in the halfway RA group. The success rate of halfway RA was 90.5%, which required switching from halfway RA to conventional RA. The incidences of slow flow and periprocedural myocardial infarction with slow flow were similar between the intentional halfway RA and matched conventional RA groups.ConclusionsThere was no burr entrapment or vessel perforation following halfway RA. The incidences of slow flow and periprocedural myocardial infarction were similar between the intentional halfway RA and the matched conventional RA, indicating the safety of halfway RA.

Project description:PurposeTo demonstrate safety and effectiveness of the novel ByCross® atherectomy system for treatment of complex femorodistal > 80% arterial stenosis.Materials and methodsFrom September 2018 until April 2019 39 patients with 41 femorodistal lesions including the femoropopliteal and distal popliteal segments were treated in a prospective, nonrandomized pre-market approval study with 6 months follow up using the ByCross® atherectomy device (ClinicalTrials.gov identifier NCT03724279). Adjunctive treatment with balloon dilatation or stenting was allowed by the protocol. Mean patient age was 72 years with 62% male. The average lesions length was 125 ± 118 mm (30 and 450 mm) with an average reference vessel diameter of 5.2 ± 0.85 mm and a mean stenosis of 96.4 ± 6.2% based on CT or MR angiography measurements. The primary performance endpoint was defined as acute procedural success with angiographically determined residual stenosis of ≤ 50% and of ≤ 30% after atherectomy or adjunctive treatment. The primary safety endpoint was the major adverse event (MAE) rate through 30 days. Secondary endpoints were stenosis of the target lesions measured by duplex ultrasound (DUS) and the ankle-brachial pressure index (ABPI) at discharge, 30 and 180 days as well as any major adverse event (MAE) through 6 months.ResultsThe acute procedural success was achieved in 39/41 (95.12%) lesions, partially without wire guidance (11/41 (26.82%)). No embolic protection was used, and adjunctive angioplasty and stenting was performed in 40/41 (97.56%) and 12/41 (29.26%) lesions, respectively without device related MAE's at 30 days. Mean level of stenosis was 5.7% at discharge and 21.7% at 6 months FU measured by DUS. Mean ABPI was 0.8, 1.0 and 0.8 at baseline, discharge, and 6 months FU respectively.ConclusionsBased on the high technical success rate and the low rates of MAE`s through six months, the BYCROSS® Atherectomy System has shown to be safe and effective for the crossing and atherectomy of complex lower-extremity arterial occlusions.Trial registrationOctober 17, 2018,retrospectively registered.Clinicaltrialsgov Identifier: NCT03724279; https://clinicaltrials.gov/ct2/show/record/NCT03724279.

Project description:BackgroundTraditionally rotablation is considered as contraindicated in presence of visible thrombus or dissection. However, clinical situations may force us to undertake rotablation in presence of thrombus or dissection. We report a case of coronary rotablation done successfully in setting of acute thrombotic occlusion over an underlying non-healed dissection.Case summaryA non-dilatable lesion in proximal left anterior descending (LAD) artery after rotablation with a 1.5 mm burr resulting in non-flow limiting Type A dissection with TIMI3 flow was left on conservative management to allow it to heal. But the patient developed ST-elevation myocardial infarction on the 9th post-intervention day due to thrombotic occlusion of the LAD at the site of dissection. At this time, we were compelled to do rotablation as a lifesaving procedure in presence of both thrombus and underlying dissection with a successful outcome.DiscussionRotablation in presence of dissection can lead to entrapment of the flap in the rotating burr leading to progression of dissection distally or sometimes there can be subintimal tracking of burr leading to perforation. In thrombotic lesions, rotablation can cause further increase in platelet activation and aggregation by the spinning burr or distal embolization of the thrombotic material promoting slow or no flow. In this unusual case with limited options for achieving successful revascularization, some out of the box steps were taken with all recommended precautions and successful outcome achieved.

Project description:BackgroundRotational atherectomy has become increasingly utilised over the past decade. Although a relatively safe procedure in appropriately trained physicians' hands, there are a number of recognised complications.Case summaryWe describe the case of a 64-year-old female who presented with chest pain and was diagnosed with non-ST-segment elevation acute coronary syndrome. A transthoracic echocardiogram (TTE) showed normal biventricular function and no valve disease. Invasive coronary angiogram was performed which revealed a severely calcified ostial right coronary artery (RCA) disease which was felt to be the culprit of the presentation. Balloon dilatation was unsuccessful, therefore, rotational atherectomy with an Amplatz left 0.75 guide and a 1.5 mm rota-burr was utilised and improved calcium burden. This was complicated by ostial dissection, treated with stenting. A TTE following the procedure revealed moderate aortic regurgitation (AR). The patient was discharged as she remained asymptomatic. An outpatient transoesophageal echocardiogram performed eight months later showed evidence of severe eccentric AR. Cardiac magnetic resonance imaging confirmed severe AR with left ventricular dilatation. Repeat angiogram 10 months after index procedure revealed in-stent restenosis, and the patient was accepted by heart multidisciplinary team for aortic valve replacement and grafting of RCA.DiscussionAs the field of rotational atherectomy continues to expand, we propose that novel complications such as reported in this case may become recognised. Finally, we stress the importance of multi-modality imaging in the investigation and timely planning of interventions in the management of these patients.

Project description:The current routine use of intracoronary stents in percutaneous coronary intervention (PCI) has significantly reduced rates of restenosis, compared with balloon angioplasty alone. On the contrary, small post-stenting luminal dimensions due to undilatable, heavily calcified plaques have repeatedly been shown to significantly increase the rates of in-stent restenosis. Rotational atherectomy of lesions is an alternative method to facilitate PCI and prevent underexpansion of stents, when balloon angioplasty fails to successfully dilate a lesion. Stentablation, using rotational atherectomy to expand underexpanded stents deployed in heavily calcified plaques, has also been reported. We report a case via the transradial approach of rotational-atherectomy-facilitated PCI of in-stent restenosis of a severely underexpanded stent due to a heavily calcified plaque. We review the literature and suggest rotational atherectomy may have a role in treating a refractory, severely underexpanded stent caused by a heavily calcified plaque through various proposed mechanisms.

Project description:A 73-year-old man presented with acute coronary syndrome secondary to stent failure. Intravascular imaging identified a recurrent protruding calcific nodule as the mechanism, which was effectively treated with low-speed rotablation, resulting in ablation of the nodule allowing the application of a drug-coated balloon.

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:IntroductionThere is increasing evidence supporting the use of intracoronary imaging to optimize the outcomes of percutaneous coronary intervention (PCI). However, there are no studies examining the impact of imaging on PCI outcomes in cases utilising rotational atherectomy (RA-PCI). Our study examines the determinants and outcomes of using intracoronary imaging in RA-PCI cases including 12-month mortality.MethodsUsing the British Cardiac Intervention Society database, data were analysed on all RA-PCI procedures in the UK between 2007 and 2014. Descriptive statistics and multivariate logistic regressions were used to examine baseline, procedural, and outcome associations with intravascular imaging.ResultsIntracoronary imaging was used in 1,279 out of 8,417 RA-PCI cases (15.2%). Baseline covariates associated with significantly more imaging use were number of stents used, smoking history, previous CABG, pressure wire use, proximal LAD disease, laser use, glycoprotein inhibitor use, cutting balloons, number of restenosis attempted, off-site surgery, and unprotected left main stem (uLMS) PCI. Adjusted rates of in-hospital major adverse cardiac/cerebrovascular events (IH-MACCE), its individual components (death, peri-procedural MI, stroke, and major bleed), or 12-month mortality were not significantly altered by the use of imaging in RA-PCI. However, subgroup analysis demonstrated a signal towards reduction in 12-month mortality in uLMS RA-PCI cases utilising intracoronary imaging (OR 0.67, 95% CI 0.44-1.03).ConclusionsIntracoronary imaging use during RA-PCI is associated with higher risk of baseline and procedural characteristics. There were no differences observed in IH-MACCE or 12-month mortality with intracoronary imaging in RA-PCI.
