Intravascular Lithotripsy as a Novel Treatment Method for Calcified Unprotected Left Main Diseases-Comparison to Rotational Atherectomy-Short-Term Outcomes.

ABSTRACT:

Background

The unprotected calcified Left Main disease represents a high-risk subset for percutaneous coronary intervention (PCI), and it is associated with a higher number of periprocedural complications and an increased rate of in-stent thrombosis and restenosis. Adequate lesion preparation plays a crucial role in achieving a favorable PCI outcome. Rotational Atherectomy (RA) is a well-established plaque-modifying method; nevertheless, the data regarding the effectiveness of RA in LM diseases is scarce. Recently, the novel ShockWave-Intravascular-Lithotripsy(S-IVL) device has been introduced to the PCI armamentarium in order to modify the calcified plaque.

Methods

We performed a retrospective evaluation of 44 consecutive subjects who underwent the LM-PCI, and who were supported by either the RA or S-IVL.

Results

The Rota group consisted of 29 patients with a mean syntax score of 28.0 ± 7.5. The S-IVL group was composed of 15 subjects with a syntax score of 23.3 ± 13.0 There were no statistical differences regarding MACE between the RA and Shockwave arms of the in-hospital group (10.3% vs. 6.7%), or in the six month (17.2% vs. 13.3%) follow-up group.

Conclusions

RA and S-IVL could be safe and effective therapeutic strategies for calcified LM disease. Further studies with a higher number of participants and longer follow-up times are warranted to establish the potential benefits of RA and S-IVL for the management of LM stenosis.

Changing paradigm for treatment of heavily calcified coronary artery disease. A complementary role of rotational atherectomy and intravascular lithotripsy with shockwave balloon: a case report.

Project description:BackgroundManagement of heavily calcified coronary arteries is still a major challenge in interventional cardiology. Inadequate stent expansion in calcific lesions is the single most important predictor of stent thrombosis and in-stent restenosis. Rotational atherectomy (RA) is an important tool to modify the calcium burden but is associated with limitations and requires specific skills. Intravascular lithotripsy (IVL) is a novel technique to treat calcified stenotic lesions and has been proposed as an alternative to RA with promising results.Case summaryWe report a case of a patient with severely calcified right coronary artery stenosis successfully treated with combination of RA and IVL.DiscussionIn this case, we demonstrate that the RA and IVL are complementary strategies, not sufficient on their own and not alternative to each other.

Halfway rotational atherectomy for calcified lesions: Comparison with conventional rotational atherectomy in a propensity-score matched analysis.

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.

Clinical Outcome of Rotational Atherectomy in Calcified Lesions in Korea-ROCK Registry.

Project description:Background and Objectives: Data is still limited regarding clinical outcomes of rotational atherectomy (RA) after percutaneous coronary intervention. We sought to evaluate clinical outcomes of RA. Materials and Methods: This multi-center registry enrolled patients who underwent RA during PCI from nine tertiary centers in Korea between January 2010 and October 2019. The primary endpoint was target-vessel failure (TVF; the composite outcome of cardiac death, target-vessel spontaneous myocardial infarction, or target-vessel revascularization). Results: Of 540 patients (583 lesions), the mean patient age was 71.4 ± 0.4 years, 323 patients (59.8%) were men, and 305 patients (56.5%) had diabetes mellitus. Technical success rate was 96.4%. In-hospital major adverse cerebral and cardiac events occurred in 63 cases (10.8%). At 1.5 years, 72 (16.0%) of TVFs were occurred. We evaluated independent predictors of TVF, which included current smoker (hazard ratio (HR), 1.92; 95% confidence interval (CI), 1.17-3.16; p = 0.01), chronic renal disease (HR, 1.87; 95% CI, 1.14-3.08; p = 0.013), history of cerebrovascular attack (HR, 2.14; 95% CI, 1.24-3.68; p = 0.006), left ventricle ejection fraction (HR, 0.98; 95% CI, 0.97-0.999; p = 0.037), and left main disease (HR, 1.94; 95% CI, 1.11-3.37; p = 0.019). Conclusions: From this registry, we demonstrated acceptable success rates, in-hospital and mid-term clinical outcomes of RA in the DES era.

Comparison of clinical outcomes of intravascular ultrasound-calcified nodule between percutaneous coronary intervention with versus without rotational atherectomy in a propensity-score matched analysis.

Project description:ObjectivesThis study aimed to compare the mid-term clinical outcomes of intravascular ultrasound (IVUS)-calcified nodules between percutaneous coronary intervention (PCI) with and without rotational atherectomy (RA).BackgroundThere has been a debate whether to use RA for the revascularization of calcified nodule. Although RA can ablate the calcified structure within calcified nodule and may facilitate adequate stent expansion, RA may provoke severe coronary perforation, because calcified nodule typically shows eccentric calcification.MethodsWe included 204 lesions with IVUS-calcified nodule, and divided into 73 lesions treated with RA (RA group) and 131 lesions without RA (non-RA group). After propensity-score matching, 42 lesions with RA (matched RA group) and 42 lesions without RA (matched non-RA group) were selected. We compared the clinical characteristics and outcomes between the 2 groups before and after propensity-score matching. The primary endpoint was ischemia-driven target vessel revascularization (TVR) within 1 year.ResultsAcute lumen area gain on IVUS was comparable between the matched RA group and matched non-RA group (3.9 ± 2.1 mm2 vs. 3.4 ± 1.6 mm2, p = 0.18). The stent malapposition at calcified nodules was frequently observed in both groups. The ischemia-driven TVR was not different between the 2 groups before (p = 0.82) and after propensity score-matching (p = 0.87).ConclusionsThe use of RA could not reduce the incidence of ischemia-driven TVR in lesions with IVUS-calcified nodule. Our results do not support the routine use of RA for lesions with IVUS-calcified nodule.

The rotational atherectomy with a guide extension catheter for calcified and tortuous lesions in left anterior descending artery: a case report.

Project description:BackgroundThe interventional treatment of calcified lesions with severe tortuosity in the left anterior descending artery (LAD) was challenging and the report of rotational atherectomy with mother-and-child technique has been scarce.Case presentationAn 84-year-old woman was hospitalized for non-ST-segment acute coronary syndrome. Coronary angiography revealed a calcified nodule in the LAD. During rotational atherectomy of the calcified and tortuous lesion in the proximal LAD, eccentric cutting due to wire bias nearly caused perforation. The burr seemed to protrude from the contrast media during angiography. Intravascular ultrasound imaging revealed that extremely eccentric ablation almost reached the adventitia. We successfully ablated the distal calcified nodule by preventing proximal overcutting of the tortuous lesion with support from a guide extension catheter, i.e., the mother-and-child technique, followed by the deployment of the drug-eluting stent. The patient was discharged without chest symptoms and no symptom recurred during 12-month follow-up.ConclusionThis case demonstrated that safe ablation of a calcified nodule located distal to a tortuous and calcified lesion in the proximal LAD with the mother-and-child technique.

Cost-effectiveness of orbital atherectomy compared to rotational atherectomy in treating patients with severely calcified coronary artery lesions in Japan.

Project description:Compared to rotational atherectomy (RA), orbital atherectomy (OA) has been shown to decrease procedure failure and reintervention rates in the treatment of severely calcified coronary artery lesions. Our objective was to explore the cost-effectiveness of OA compared to RA in the Japanese healthcare system. A decision-analytic model calculated reintervention rates and consequent total 1-year costs. Effectiveness inputs were therapy-specific target lesion revascularization (TLR) rates and all-cause mortality, pooled from clinical studies. Index and reintervention costs were determined based on claims data analysis of n = 33,628 subjects treated in 2014-2016. We computed incremental cost-effectiveness in Japanese Yen (JPY) per life year (LY) gained based on differences in 1-year cost and projected long-term survival, assuming OA device cost between JPY 350,000 and ?JPY 550,000. OA was found to be associated with improved clinical outcomes (12-month TLR rate 5.0 vs. 15.7%) and projected survival gain (8.34 vs. 8.16 LYs (+0.17), based on 1-year mortality of 5.5 vs. 6.8%). Total 1-year costs were lower for device cost of JPY 430,000 or less, and reached a maximum ICER of JPY 753,445 per LY at the highest assumed device cost, making OA dominant or cost-effective across the tested range, at ICERs substantially below the willingness-to-pay threshold. In conclusion, orbital atherectomy for the treatment of severely calcified coronary artery lesions, compared to rotational atherectomy, is a cost-effective treatment approach in the Japanese healthcare system due to improved clinical performance.

Successful rotational atherectomy of left main stem with double kiss crush stenting using double guiding catheter: a case report.

Project description:BackgroundCoronary artery bypass grafting is the preferred revascularization procedure for patients with multivessel disease, and those with complex left main disease, as it is associated with a survival advantage in this group of patients. Sometimes however surgical management is not the treatment of choice due to many factors including ongoing chest pain, haemodynamic instability, or patient preference. In these situations, percutaneous coronary intervention (PCI) offers an alternative revascularization strategy. In this case study, we present a successful PCI with rotational atherectomy (RA) for distal left main stem (LMS), left anterior descending (LAD), and circumflex artery (CX) using a double guide catheter technique in a patient with severe calcific disease.Case summaryA 63-year-old female was diagnosed with a non-ST-elevation myocardial infarction. Coronary angiography showed significant distal LMS disease with a severe proximal/ostial calcified lesion of the LAD and a possible thrombotic lesion at the ostium of the CX. She had ongoing haemodynamic instability with chest pain however could not be offered immediate surgical revascularization. We therefore elected to proceed to complex bifurcation LMS coronary intervention using RA under intravascular ultrasound (IVUS) guidance achieving an excellent final result with TIMI III flow.DiscussionThis case demonstrates that RA using the double catheter technique (also known as Ping-Pong) can be safely performed with minimal complication rates and with very favourable angiographic and IVUS results. The clinical outcome was excellent with early discharge.

Sex differences in clinical outcomes after rotational atherectomy of calcified coronary stenoses: from multicenter registry.

Project description:BackgroundRecent improvements in devices and medications may diminish the risk of adverse events following percutaneous coronary intervention (PCI) in women. However, complex calcified coronary lesions are increasingly being encountered in clinical practice, which remain challenging for contemporary PCI. Rotational atherectomy (RA) of severely calcified lesions is an option that facilitates the technical success of PCI. We aimed to examine sex differences in long-term clinical prognoses after PCI with RA in the drug-eluting stent (DES) era.Methods and resultsWe evaluated J2T ROTA registry data from 1,090 patients with severely calcified de novo coronary artery stenoses who underwent PCI using RA at 3 hospitals between 2004 and 2015. After excluding patients who received regular hemodialysis, 788 patients, including 570 men and 218 women, were ultimately analyzed. The primary endpoint was major adverse cardiovascular and cerebrovascular events (MACCE), which included death, acute coronary syndrome (ACS), and stroke. The women were significantly older, and presented more frequently with chronic kidney disease, ACS, atrial fibrillation, lower body mass indexes, and worse lipid profiles than the men. During the observation period, MACCE occurred in 197 patients (25%) (118 deaths, 29 strokes, and 50 ACS). In the unmatched population, women had a higher MACCE rate than men (hazard ratio: 1.48, [95% confidence interval: 1.07-2.06]). However, sex was not associated with MACCE in the propensity score-matched population.ConclusionIn the DES era, differences between sexes were not observed in relation to long-term MACCE in patients undergoing PCI with RA for severely calcified coronary artery stenoses.
