OBJECTIVES: Using intravascular ultrasound (IVUS), the authors compared outcomes by observed wire position (intraplaque vs. subintimal) achieved during successful chronic total occlusion (CTO) lesion treatment. BACKGROUND: Recent successes in CTO percutaneous coronary intervention (PCI) have used both intraluminal and subintimal wire tracking to improve procedural success. IVUS may be used to determine the course of wire tracking after crossing a CTO. METHODS: From March 2014 to March 2016, data were collected into a single-center database from 219 patients undergoing CTO PCI with concomitant IVUS imaging...

In this study we investigated whether exerting an impulse on a Chronic Total Occlusion (CTO) improves the success rate of CTO crossing as compared to the currently used method of statically pushing the guidewire against the CTO. A prototype (Ø2 mm) was developed that generates translational momentum using a spring-loaded indenter and converts it to an impulse during impact. Mechanical performance was evaluated by measuring the peak force and momentum for different spring compressions and strike distances in air and blood-mimicking fluid...

AIM: To investigate the rates and determinants of success of repeat percutaneous coronary intervention (PCI) following an initial failed attempt at recanalising the chronic total occlusions (CTO) percutaneously. METHODS: In 445 consecutive first attempt CTO-PCI procedures in our institution, procedural failure occurred in 149 (33.5%). Sixty-four re-PCI procedures were performed in 58 patients (39%) all had a single CTO. Procedural and outcome data in the re-PCI population was entered into the institutional database...

We sought to examine the impact of calcific deposits on the outcomes of chronic total occlusion (CTO) percutaneous coronary intervention (PCI). The outcomes of 1,476 consecutive CTO PCIs performed in 1,453 patients (65.5 ± 10 years, 85% male) between 2012 and 2016 at 11 US centers were evaluated. Moderate or severe quantity of calcium was present in 58% of target lesions. Calcified lesions were more tortuous and more likely to have proximal cap ambiguity and interventional collaterals. PCI of moderately/severely calcified CTOs more often required use of the retrograde approach (54% vs 30%, p <0...

The prevalence of radial access for transradial catheterization remains low in the United States, occurring in only 28% of cases in the National Cardiovascular Data Registry (NCDR) CathPCI. It is unknown whether the low adoption rate has been influenced by patient characteristics or is more operator dependent. In a 10-center study, we compared clinical and demographic characteristics among 323 radial and 1,506 femoral access percutaneous coronary intervention (PCIs) performed by 65 interventionists capable of radial PCI...

Failure to cross with a guidewire is the most common reason for failure of chronic total occlusion (CTO) percutaneous coronary intervention (PCI). In cases of CTO PCI with no interventional collaterals, an intravascular ultrasound (IVUS)-guided parallel wire technique is usually the last-resort procedure. Failure of this technique sometimes causes enlarged subintimal space, resulting in procedure failure. We present a successful second attempt at left anterior descending artery CTO PCI with no interventional collaterals...

BACKGROUND: The duration of dual antiplatelet therapy (DAPT) after drug-eluting stent implantation in coronary chronic total occlusion (CTO) remains unclear. METHODS: We retrospectively analyzed a total of 512 patients treated with percutaneous coronary intervention (PCI) in the Samsung Medical Center CTO registry. Patients were separated into ≤ 12-month (199, 38.9%) vs. > 12 month (313, 61.1%) based on DAPT duration with aspirin and clopidogrel. The primary outcome was major adverse cardiac and cerebrovascular event (MACCE) during follow-up...

OBJECTIVES: This study sought to compare long-term clinical outcome in ST-segment elevation myocardial infarction (STEMI) patients with a concomitant chronic total occlusion (CTO) with well-developed versus poorly developed collaterals toward the CTO. BACKGROUND: In STEMI patients, presence of a CTO is associated with increased morbidity and mortality. CTOs are often (partially) perfused by collateral vessels. Therefore, when the infarct-related artery (IRA) is the main donor vessel for the collateral blood supply of the CTO, infarct size may increase significantly...

OBJECTIVES: This study sought to create a contemporary scoring tool to predict technical outcomes of chronic total occlusion (CTO) percutaneous coronary intervention (PCI) from patients treated by hybrid operators with differing experience levels. BACKGROUND: Current scoring systems need regular updating to cope with the positive evolutions regarding materials, techniques, and outcomes, while at the same time being applicable for a broad range of operators. METHODS: Clinical and angiographic characteristics from 880 CTO-PCIs included in the REgistry of CrossBoss and Hybrid procedures in FrAnce, the NetheRlands, BelGium and UnitEd Kingdom (RECHARGE) were analyzed by using a derivation and validation set (2:1 ratio)...

Conflicting evidence exists on gender differences in outcomes after coronary stenting, and gender-based data in patients with chronic total occlusions (CTO) who underwent percutaneous coronary intervention (PCI) are scarce. Consecutive patients who underwent CTO PCI from January 2005 to December 2013 were included in the analysis and stratified according to gender. The primary outcome measure was all-cause mortality. Median follow-up was 2.6 years (interquartile range 1.1 to 3.1). Of 2002 patients, 332 (17%) were women...

The careful assessment of collateral channels is important for a retrograde approach for a chronic total coronary occlusion (CTO). This case report describes a percutaneous coronary intervention for CTO of the distal right coronary artery with good collateral circulation. All visible collateral channels failed by the retrograde approach; however, the procedure was successful using the distal atrial circumflex (AC) channel. Although this distal channel was poorly visualized on standard coronary angiography, it was clearly contrasted retrogradely from the CTO exit using a super-selective injection through the proximal AC channel as the antegrade flow was obstructed by the anchor balloon...

Yader Sandoval, Emmanouil S Brilakis
Rotational atherectomy is performed infrequently (∼3.5%) during chronic total occlusion (CTO) percutaneous coronary intervention (PCI) for two indications: treatment of balloon uncrossable and balloon undilatable lesions. Use of rotational atherectomy in CTO PCI was associated with high success and acceptable complication rates. Rotational atherectomy remains a "must have" device for interventional cardiologists performing complex PCI.

Dissection and re-entry (DR) techniques have played a key role in the increase of success rates of chronic total occlusion (CTO) recanalization. DR usually allows wiring complex occlusions, even in case of important calcification. In extreme cases, such as in balloon failure-to-cross, rotational atherectomy (RA) might be decisive. However, according to experts' recommendations, RA should not be performed in dissection planes because of the high risk of perforation and further extending the dissection, so that its use after DR might be limited...

OBJECTIVES: The study sought to investigate the long-term outcomes and predictors of adverse events of percutaneous coronary intervention (PCI) for in-stent chronic total occlusion (IS-CTO). BACKGROUND: IS-CTO PCI has traditionally been associated with suboptimal success rates. METHODS: We performed a multicenter registry of consecutive patients undergoing CTO PCI at 3 specialized centers. Patients were divided in IS-CTO and de novo CTO. The primary endpoint (major adverse cardiac events [MACE]) was a composite of cardiac death, target-vessel myocardial infarction, and ischemia-driven target-vessel revascularization (TVR) on follow-up...
