Sex differences in procedural and clinical outcomes following rotational atherectomy. Catheter Cardiovasc Interv 2020; 95:232-241.

Abstract
AIM Evaluate sex differences in procedural net adverse clinical events and long-term outcomes following rotational atherectomy (RA). METHODS AND RESULTS From 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). CONCLUSION Women 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.

Abstract
Mechanical debulking of coronary plaques with rotational atherectomy (RA) has been used for more than 20 years during percutaneous coronary interventions (PCI). Modification of plaque characteristics may be accomplished with selective ablation of inelastic fibrocalcific tissue. The use of RA, though reduced with the development of bare-metal stents (BMS) and even more with drug-eluting stents (DES), has never been completely abandoned. The present review will analyze reasons for conflicting results obtained in large series and randomized trials on this topic in the past, and will identify criteria for an appropriate use in current times.

Abstract
We conducted a prospective observational study to evaluate the indications, technique, in-hospital and 9-month results of consecutive patients treated with rotational atherectomy (RA) in 12 centers during 1 year, as well as their relationship with volume of RA activity. The study included 345 lesions in 289 patients treated (4.4% +/- 2.6% of procedures at the participating centers). The lesions were mostly calcified (63%) and type B2 or C (74%). Procedural success was obtained in 94% of patients, with a major adverse cardiac event (MACE) rate of 4.5%. At 9 months, MACE occurred in 17.3%. Multivariate analysis identified multivessel disease and slow flow as negative predictors of procedural success, whereas balloon pressure <or= 6 atm and hypercholesterolemia were associated with decreased MACE at 9 months. Center RA volume was not associated with in-hospital or 9-month outcome. We conclude that RA, even when used sporadically in selected complex lesions, can provide good immediate and mid-term results.

Abstract
To evaluate the acute effect of pretreatment with high-speed rotational atherectomy (HSRA) on stent deployment (rotastenting), we studied 33 patients with rotastenting of 40 segments, 34 patients with 40 coronary segments treated with Palmaz-Schatz stenting alone, and 34 patients with 40 segments treated with HSRA. The HSRA- and stent-alone patient groups were selected retrospectively by matching the quantitative coronary angiography (QCA) reference diameter (D ref). QCA revealed similar baseline percent of stenosis (85.3% +/- 12.4%), minimal luminal diameter (MLD), and D ref. The percent area expansion was calculated as a ratio between the minimal intrastent area and the reference area measured by intracoronary ultrasound. The rotastent group was characterized by more frequent calcification compared to HSRA and stent groups (67.5% vs. 20% and 12.5%; P < 0.01). Lesion length determined by QCA was longer both in the HSRA and the rotastent groups vs. the stent-alone group (21.1 +/- 12.3 and 20.9 +/- 4.3 vs. 17.0 +/- 7.7 mm; P < 0.05). In this small study, there was no difference demonstrated between final MLD in the rotastent and stent-alone groups. However, a smaller MLD was achieved in the HSRA group (3.0 +/- 0.7 vs. 3.1 +/- 0.5 vs. 2.5 +/- 0.7 mm, respectively; P < 0.01). The degree of stent expansion was higher in the rotastent group compared to the stent-alone group (91.9% +/- 4.4% vs. 79.7% +/- 3.4%; P < 0.03) and the % residual area of plaque was less for the rotastent group than for the stent-alone group (12.1% +/- 13.2% vs. 21.1% +/- 17.5%; P = 0.03). These data suggest that antecedent HSRA atheroma debulking using HSRA results in improved intravascular stent expansion and reduction in residual plaque, facilitating optimal stent deployment.

Abstract
BACKGROUND Postinterventional ischemic myocardial dysfunction and its sequelae are still not well understood. METHODS AND RESULTS To gain further insight into the immediate physiologic consequences of coronary interventions and to better understand the nature of changes that result from such interventions, we analyzed 96 electromechanical maps from 48 patients before and after successful, uncomplicated percutaneous coronary interventions (PCI). A NOGA system was used to construct the map of the endocardial surface. Reproducibility was confirmed by constructing 10 additional maps in 5 patients who did not undergo an intervening procedure. Discordant areas were defined as those with preserved unipolar voltage (> or =7.5 mV) and diminished linear local shortening (< or =12.5%). On the basis of comparison of the variations in the discordance values (%) in the reproducibility group, patients were considered improved (lower values), worsened (higher values), or unchanged. In the reproducibility group, the mean variation in discordance was 2.18% +/- 1.26%, whereas in the PCI group, it was 21.97% +/- 18.47%. In the PCI group (rotational atherectomy subgroup [n = 10] and stent subgroup [n = 38]), left ventricular discordance values improved in 19 patients (39.6%), worsened in 24 (50%), and remained the same in 5 (10.4%). Of all variables analyzed, only abciximab was significantly associated with postintervention improvement in discordance (P =.02; odds ratio 0.165, 95% CI 0.03-0.88), regardless of the type of intervention performed (P =.61), whereas heparin alone was associated with more discordance after intervention (odds ratio 6.07, 95% CI 1.14-32.40). CONCLUSIONS We assessed the effect of percutaneous revascularization on myocardium by use of electromechanical data. For the first time, changes in linear local shortening in areas of preserved unipolar voltage were quantified, and worsening after successful Thrombolysis In Myocardial Infarction grade III coronary interventions was registered. The only variable associated with improvement on electromechanical data after interventions was the use of abciximab. This raises the question of the possible potential of this new diagnostic tool in assessing and quantifying postinterventional microvasculature pathological changes.

Abstract
Mechanical rotational atherectomy with the Rotablator is widely used for percutaneous coronary revascularization, but the ideal debulking strategy remains unknown. The purpose of this study was to compare the immediate and late results after Rotablator using two treatment strategies: Large burrs (burr/artery ratio of >0.7) to achieve maximal debulking (lesion debulking strategy) or small burrs (burr/artery ratio < or = 0.7) to modify lesion compliance (lesion modification strategy). Two hundred twenty-two patients at six centers were prospectively enrolled in this study and randomly assigned to large (n = 104 patients with 118 lesions) or small (n = 118 patients with 136 lesions) burrs. The primary endpoint was final diameter stenosis at the end of the procedure, and secondary endpoints included inhospital angiographic and clinical complications, and target lesion revascularization at 6 months. Baseline demographic and angiographic characteristics were similar. There were no differences in procedural success, the extent of immediate lumen enlargement, inhospital ischemic complications, or late target vessel revascularization. However, compared with small burrs, patients randomized to large burrs were more likely to experience serious angiographic complications (5.1% vs. 12.7%, P < 0.05) immediately after atherectomy. This study suggests that a routine lesion modification strategy employing small burrs (burr/artery ratio < or = 0.7) achieves similar immediate lumen enlargement and late target vessel revascularization compared with a more aggressive debulking strategy (burr/artery ratio >0.7), but with fewer angiographic complications.

Abstract
Rotational atherectomy is used to debulk calcified or complex coronary stenoses. Whether aggressive burr sizing with minimal balloon dilation (<1 atm) to limit deep wall arterial injury improves results is unknown. Patients being considered for elective rotational atherectomy were randomized to either an "aggressive" strategy (n = 249) (maximum burr/artery >0.70 alone, or with adjunctive balloon inflation < or = 1 atm), or a "routine" strategy (n = 248) (maximum burr/artery < or =0.70 and routine balloon inflation > or =4 atm). Patient age was 62 +/- 11 years. Fifty-nine percent routine and 60% aggressive strategy patients had class III to IV angina. Fifteen percent routine and 16% aggressive strategy patients had a restenotic lesion treated; lesion length was 13.6 versus 13.7 mm. Reference vessel diameter was 2.64 mm. Maximum burr size (1.8 vs 2.1 mm), burr/artery ratio (0.71 vs 0.82), and number of burrs used (1.9 vs 2.7) were greater for the aggressive strategy, p <0.0001. Final minimum lumen diameter and residual stenosis were 1.97 mm and 26% for the routine strategy versus 1.95 mm and 27% for the aggressive strategy. Clinical success was 93.5% for the routine strategy and 93.9% for the aggressive strategy. Creatine kinase-myocardial band (CK-MB) was >5 times normal in 7% of the routine versus 11% of the aggressive group. CK-MB elevation was associated with a decrease in rpm of >5,000 from baseline for a cumulative time >5 seconds, p = 0.002. At 6 months, 22% of the routine patients versus 31% of the aggressive strategy patients had target lesion revascularization. Angiographic follow-up (77%) showed minimum lumen diameter to be 1.26 mm in the routine group versus 1.16 mm in the aggressive group, and the loss index 0.54 versus 0.62. Dichotomous restenosis was 52% for the routine strategy versus 58% for the aggressive strategy. Multivariable analysis indicated that left anterior descending location (odds ratio 1.67, p = 0.02) and operator-reported excessive speed decrease >5,000 rpm (odds ratio 1.74, p = 0.01) were significantly associated with restenosis. Thus, the aggressive rotational atherectomy strategy offers no advantage over more routine burr sizing plus routine angioplasty. Operator technique reflected by an rpm decrease of >5,000 from baseline is associated with CK-MB elevation and restenosis.

Abstract
The acute angiographic and long-term clinical outcomes of a consecutive series of patients treated with the coronary rotablator at a single center are described. The patient population was a high-risk population, with significant instances of unstable angina or acute myocardial infarctions (MI) on presentation (75.5%), three-vessel coronary artery disease (27.5%), congestive heart failure (23.8%), and diabetes (39%). The coronary anatomy was also complex, with 79.3% of lesions treated being National Heart Lung and Blood Institute (NHLBI) class B or C. The maximum burr:artery ratio averaged 0.79+/-0.11. The maximum balloon:artery ratio averaged 1.19+/-0.17. Acute procedural success was 90%. The reference vessel diameter was 2.72 mm +/-0.54 mm. The average minimum luminal diameter (MLD) preprocedure was 0.87+/-0.31 mm. The average MLD postprocedure was 2.01+/-0.54 mm. The acute gain averaged 1.14+/-0.51 mm. Urgent coronary artery bypass grafting was required in 1% of patients. Subendocardial infarctions occurred in 8.5% of patients, and abrupt closure postprocedure while in hospital occurred in 1% of patients. Reinterventions or coronary artery bypass grafting (CABG) in hospital occurred in only 3.5% of patients; 96% of patients were available for a long-term clinical follow-up. Repeat coronary interventions for target lesion revascularizations were required in 17.4% of patients, coronary artery bypass grafting for target lesion revascularization was necessary in 9.5% of patients, and the combined target lesion revascularization rate was 25.3% at 1 year. Subsequent Q-wave myocardial infarctions or cardiac death occurred in 5.7% of patients at 1 year. Event-free survival was 75.1% at 6 months and 69.9% at 1 year. The strongest predictor of subsequent target lesion revascularization was lesion length (P=0.034) and not the postprocedure MLD (P=0.41). Most major adverse clinical events occurred within the first 4 months and greater than 90% of all major adverse clinical events occurred within the first 6 months. The coronary rotablator was able to achieve a high degree of clinical success in a high-risk patient population with complex anatomy. Most major adverse clinical events occurred early (<6 months) and were comprised principally of target lesion revascularizations. The overall target lesion revascularization rates and combined major adverse clinical event rates are favorable, given the complex anatomy and the high proportion of diabetics, females, and multivessel disease patients treated in this series.

Abstract
We present our single-center experience of rotational atherectomy (RA) in the first 1,000 consecutive patients divided arbitrarily into three different time periods corresponding to significant changes in technique or equipment for RA. Period I (August 1994 to April 1995; 172 cases) is characterized by early experience, longer ablation, and frequent use of intra-aortic balloon pump; period II (May 1995 to January 1996; 254 cases) is characterized by short ablation runs (20-30 sec) and use of rotaflush; period III (February 1996 to February 1997; 574 cases) is characterized by ReoPro use, neosynephrine boluses to avoid hypotension, and rota floppy wire and flexible shaft burrs. The procedural success rate has improved and complication rates have progressively declined over these three time periods. The incidence of lesion complexity (long and type C lesions) and patients with unstable rest angina have increased over these time periods of RA. Therefore, modification in procedural techniques and equipment over time have made RA a safe technique despite its use in very complex lesion subsets.

Abstract
Rotational atherectomy is effective acutely in treating complex coronary disease, but less is known about its long-term clinical outcome. We examined the acute results and late clinical outcome in 178 patients undergoing treatment with this device. Rotational atherectomy was used to treat 240 lesions in 178 individual patients. Nineteen percent had multilesion or staged multivessel procedures, and 71% had AHA-ACC Type B2/C lesions. The procedure was completed successfully in 94% of patients. Major complications occurred in 6% (death 1%, Q-MI 2.8%, and emergency bypass surgery 2.2%). Clinical follow-up was available for 167 (94%) patients at 13+/-6 months. Thirty-five percent required additional catheterization because of recurrent symptoms or an abnormal stress test. Clinical restenosis was confirmed in 18%, and an additional 2.2% of patients had progression of disease in previously untreated segments. At the end of 1 year, 14% had undergone repeat target vessel revascularization. Cumulatively at follow-up, approximately 80% had avoided an acute major complication and repeat revascularization for restenosis. Rotational atherectomy provides excellent acute and good late clinical results. At 1 year follow-up, the likelihood of developing clinical restenosis or significant progression of disease was 1 in 5, and patients had a 1 in 7 chance of requiring revascularization because of restenosis. These findings are encouraging and indicate that rotational atherectomy can be performed safely and with a high degree of acute and late clinical success in complex coronary disease characterized by multivessel or multilesion involvement and a predominance of B2 and C lesions.

Abstract
BACKGROUND Rotational atherectomy with the Rotablator catheter has improved percutaneous treatment of certain coronary atherosclerotic lesions, but the "no-reflow" phenomenon remains a serious complication. Because platelet activation by rotablation may contribute to the no-reflow phenomenon, we developed an in vitro system to test the effect of rotablation on platelets in the absence or presence of platelet GP IIb/IIIa receptor blockade with abciximab. METHODS AND RESULTS Platelet-rich plasma (PRP) was prepared from 28 healthy human volunteers. PRP was divided into 4 samples: (1) no treatment, (2) 6D1 (anti-GP Ib), (3) c7E3 Fab (anti-GP IIb/IIIa+alpha(v)beta3), and (4) c7E3 Fab+6D1. Samples were pumped through a flow chamber containing a 2.5-mm burr rotating at various speeds and then placed in an aggregometer. PRP samples tested in the absence of antibody underwent more rapid and extensive aggregation when rotablated at 150000 and 180000 rpm compared with 0 rpm (P<0.001 at both speeds). Preincubation of platelets with c7E3 Fab decreased the slope of aggregation at each rotablation speed, with 98%, 79%, and 71% reductions at 70000, 150000, and 180000 rpm, respectively (P=0.09 for 70000 and P<0.001 for both 150000 and 180000 rpm). Preincubation of platelets with 6D1 did not decrease the slope of aggregation at any rotablation speed (P>0.5, P=0.99, and P=0.091 for 70000, 150000, and 180000 rpm). Platelet ATP release, a marker of granule release and cell damage, was markedly increased at 180000 rpm (P=0.002 compared with 0 rpm in the control group). Electron microscopy revealed extensive rotablation-induced platelet damage at 150000 and 180000 rpm, and leakage of LDH confirmed platelet lysis at these speeds (P=0.002 and P<0.001 compared with 0 rpm). CONCLUSIONS High-speed rotablation induces platelet activation of PRP, leading to aggregation; pretreating PRP with abciximab decreases the aggregation. These data suggest that pretreatment of patients with abciximab may decrease rotablation-induced platelet aggregation during rotational atherectomy.

Abstract
Coronary angioplasty has changed dramatically in the past three years with major reductions in suboptimal results and restenosis rates, and improvements in safety, efficacy and cost-effectiveness. Intracoronary stent implantation with optimisation of strut expansion and the abandonment of anticoagulants after deployment, have led to less entry-site complications, facilitated early hospital discharge, virtually abolished subacute stent thrombosis and resulted in a 50% reduction in target vessel revascularisation. Adjuvant medical treatment with anti-platelet agents, including glycoprotein IIb/IIIa receptor inhibitors, improves the safety of angioplasty and may further reduce the restenosis rate. Selective use of debulking devices has extended the indications for angioplasty. High resolution fluoroscopy, quantitative coronary angiography and intracoronary ultrasound leading to improved diagnosis, equipment selection and treatment have contributed to better outcomes. Further clinical trials will compare angioplasty and stent implantation with coronary bypass surgery in patients with multivessel coronary disease, and may extend the indications for percutaneous transluminal coronary angioplasty (PTCA) to selected patients with three vessel disease.

Abstract
OBJECTIVES We compared an early registry of rotational atherectomy with a recent registry to examine the evolution of patient profiles, lesion characteristics and procedural outcomes for patients treated with rotational atherectomy. BACKGROUND With increased experience, the selection of patients and lesions treated with a device matures. This study documents the changes in the application of rotational atherectomy. METHODS The patient characteristics and procedural outcomes from two multicenter patient registries-Registry I: 2,953 procedures, 3,717 lesions from 1988 to 1993; and Registry II: 200 procedures, 268 lesions from 1994-were analyzed and compared. RESULTS There was an increase in the average age of the patients (63 vs. 65 years, p < 0.02) and the proportion of patients with unstable angina (42.9% vs. 56.5%, p < 0.01) or previous coronary artery bypass graft surgery (18.8% vs. 24.5%, p < 0.05) in Registry II. Registry II included fewer left anterior descending coronary lesions (46.5% vs. 32.8%, p < 0.01), more type B and C lesions (83.1% vs. 91.8%, p < 0.01), more eccentric lesions (69.0% vs. 79.5%, p < 0.01) and more calcified lesions (50.3% vs. 69.4%, p < 0.01). Complications, including urgent bypass surgery, Q and non-Q wave myocardial infarction, dissection, acute occlusion and perforation, were similar in the two groups. However, mortality increased from 1.0% to 3.0% (p < 0.05) in Registry II. CONCLUSIONS Comparison of recent and early patients treated with rotational atherectomy revealed an increase in the complexity of patients and lesions. Although the rate of death was increased, the overall rate of major complications was not significantly changed (4.7% vs. 6.0%, p = NS).
