Background: Stent underexpansion is a challenge in interventional cardiology. Some off-label treatments, such as rotational atherectomy, intravascular lithotripsy (IVL) and coronary lasing, have been used to overcome the problem. The purpose of this study is to evaluate the safety and efficacy of coronary laser atherectomy with simultaneous contrast injection and subsequent balloon dilation to optimize stent expansion.

Objectives: Coronary lithotripsy (CL) works by fracturing the calcified plaque, allowing mean area gain, enhancing vessel compliance, and facilitating stent deployment. This study reports the safety, effectiveness, and durability of the clinical benefit of CL at long-term follow-up of a real-world multicenter registry.
Methods: This was a prospective, multicenter, single-arm study that included consecutive patients with calcified lesions undergoing CL from August, 2018 to October, 2020 with a clinical follow-up of 20 months (interquartile range, 14.
Introduction And Objectives: Transthyretin cardiac amyloidosis (ATTR-CA) patients often have atrial fibrillation and increased bleeding/thrombogenic risks. We aimed to evaluate outcomes of left atrial appendage closure (LAAC) compared with patients without a known diagnosis of CA.
Methods: Comparison at long-term of patients diagnosed with ATTR-CA who underwent LAAC between 2009 and 2020 and those without a known diagnosis of CA.
Introduction And Objectives: Transfemoral access is the most frequently used vascular approach in chronic total occlusion percutaneous coronary interventions (CTO-PCI). The aim of this study was to evaluate the safety and feasibility of a transradial access CTO-PCI program and its impact on angiographic and clinical results and length of hospital stay.
Methods: Retrospective multicenter cohort study including 2550 consecutive CTO-PCI procedures included in a multicenter registry with accurate information on vascular access.
Background: It is unknown whether the availability of long drug-eluting stents modify the PCI strategy of long CTO. To describe the contemporary PCI strategy of long chronic total occlusions (CTO) using overlapping (OS) or single long stents (SS) and to analyze its results.
Methods: 2842 consecutive CTO PCIs were included.
The diagnosis of ischemic cardiomyopathy is not well established. Our objective is to determine predictive variables of coronary disease in unselected patients with ventricular dysfunction. This study is a retrospective cohort study of consecutive patients with left ventricular dysfunction and no known history of ischemic heart disease.

This study compares -procedural results of LAAO with Watchman FLX (Boston Scientific, Marlborough, Massachusetts) in centers with varying degrees of experience with the Watchman 2.

The cohort of 527 CTO-PCIs was divided into first-attempt and re-attempt groups, and angiographic characteristics, level of complexity, and contributing factors to failure were analyzed. Between-group success rate difference and potential angiographic and technical aspects contributing to the success in new attempts were scrutinized.

The Cre8 EVO stent releases a formulation of sirolimus with an amphiphilic carrier from laser-dug wells, and has shown clinical benefits in diabetes. We aimed to compare Cre8 EVO stents to Resolute Onyx stents (a contemporary polymer-based zotarolimus-eluting stent) in patients with diabetes.

The scores principally include anatomic and clinical variables. Operator experience is a decisive factor for achieving successful result.

Methods: Patients were included in the prospective, consecutive Iberian CTO registry (32 centers in Spain and Portugal), from 2015 to 2020.
Background: Several scoring systems have been described to assess the level of difficulty and to predict the probability of success of percutaneous coronary intervention (PCI) of chronic total occlusion (CTO). The J-CTO score was initially developed to correlate CTO complexity with guidewire time crossing through the lesion within 30 min. Moreover, almost all scoring systems represent procedures performed by seasoned operators.

Methods: Scores were calculated using raw data from 1,342 chronic total occlusion procedures included in REBECO Registry that includes learning and expert operators. Calibration, discrimination and reclassification were evaluated and compared.
Background: Coronary laser is a long-established coadjuvant therapy in interventional cardiology. This study aimed to present our experience regarding the safety and efficacy of laser assistance to percutaneous coronary intervention (PCI) in different scenarios of coronary artery disease.
Methods: We used coronary laser as an adjunctive therapy for PCI between May 2014 and March 2020.

Introduction And Objectives: Coronary lithoplasty (CL) is a balloon-based technique used to treat calcified lesions. This study reports the initial experience of treatment of calcified lesions with CL in an unselected and high-risk population.
Methods: This was a prospective, multicenter registry, which included all consecutive cases with calcified coronary lesions that underwent CL between August, 2018 and August, 2019.
Device uncrossable lesions are a challenge in interventional cardiology and despite improvements in balloon and microcatheter profile, rotational atherectomy is necessary in some circumstances in order to ablate and traverse the lesion. Nevertheless, the application of rotational atherectomy requires utilization of a specific wire, Rotawire, which is not always so easily navigable. Debulking of device uncrossable lesions can be performed by coronary laser over any kind of angioplasty guidewire.
