Comparative Short-Term Outcomes of Double-Kissing Culotte and Culotte Techniques in Acute Coronary Syndrome from the Lower Silesia Culotte Bifurcation Registry.

The double-kissing (DK) culotte technique is a modification of the culotte technique that employs initial kissing balloon inflation after first stent implantation. The DK culotte technique may improve strut apposition and procedural outcomes; however, data on its efficacy and safety remain limited. This study aimed to investigate the short-term outcomes of bifurcation percutaneous coronary intervention (PCI) using the DK culotte technique compared with those of the culotte technique in patients with acute coronary syndrome (ACS).

Evaluation of Small Vessel Bifurcation Stenting Using the Double-Kissing Culotte and Culotte Technique in Acute Coronary Syndrome: 12-Month Clinical Outcomes.

Introduction: Patients with small vessels who undergo percutaneous coronary intervention (PCI) with subsequent multiple implantation of drug-eluting stents remain at a higher risk of unfavorable outcomes. In complex cases where maintaining flow to all side branches is part of contemporary practice, using two-stent techniques may be appropriate. This study aims to evaluate the efficacy of double-kissing (DK) culotte technique in comparison to culotte technique in the context of small-vessel therapy in patients with acute coronary syndrome (ACS).

Safety and Effectiveness of Coronary Sinus Reducer in the Therapy of Refractory Angina Pectoris-Mid-Term Results of the Real-Life Cohort.

Despite continuous improvements in revascularization techniques, refractory angina without potential revascularization options remains a relevant clinical issue with significant impact on the patient's quality of life. Recently, a novel device, the Coronary Sinus Reducer (CSR), has been introduced into clinical practice as a therapeutic option for patients with disabling angina pectoris. In this single-center, observational study, we evaluated the mid-term (3-month) safety and efficacy of the CSR in a real-world cohort.

Two-Year Outcomes for Patients with Non-ST-Elevation Acute Coronary Syndrome Treated with Magmaris and Absorb Bioresorbable Scaffolds in Large-Vessel Lesions.

Background: The acute coronary syndrome (ACS) continues to be a fundamental indication for revascularization by percutaneous coronary intervention (PCI). Drug-eluting stent (DES) implantation remains a part of contemporary practice but permanent caging of the vascular structure with the metallic stent structure may increase the rate of device-related adverse clinical events. As an alternative to classic metallic DESs, the bioresorbable scaffolds (BRSs) have emerged as a temporary vascular support technology.

Frequency of periprocedural myocardial injury and infarction stratified by cardiac troponin I and cardiac troponin T.

Background: There are different definitions of periprocedural myocardial infarction (PPMI) both in terms of thresholds for cardiac biomarkers and the ancillary criteria for myocardial ischemia. Cardiac Troponin I (cTnI) and cardiac Troponin T (cTnT) are used interchangeably to diagnose PPMI.

Objectives: This study evaluated the frequency of periprocedural myocardial injury and infarction as defined by the Society of Cardiovascular Angiography & Interventions (SCAI), the Academic Research Consortium-2 (ARC-2), and the 4th Universal definition of MI (4UDMI) stratified using cTnT versus cTnI, among patients with chronic coronary syndrome (CCS) and unstable angina.

Magnesium bioresorbable scaffold (Magmaris) versus polymer biodegradable ultrathin drug-eluting stent (Ultimaster) in acute coronary syndrome. Mid-term outcomes (2 years).

Introduction: Acute coronary syndrome (ACS) is a well-known risk factor for adverse clinical outcomes in percutaneous coronary intervention (PCI). Therefore, evaluation of coronary stents in this challenging clinical scenario can provide unique information on device safety and efficacy. Bioresorbable scaffolds (BRS) were designed to overcome long-term complications related to permanent vessel caging with a permanent metallic drug-eluting stent (DES).

Multicenter registry of Impella-assisted high-risk percutaneous coronary interventions and cardiogenic shock in Poland (IMPELLA-PL).

Background: Impella is a percutaneous mechanical circulatory support device for treatment of cardiogenic shock (CS) and high-risk percutaneous coronary interventions (HR-PCIs). IMPELLA-PL is a national retrospective registry of Impella-treated CS and HR-PCI patients in 20 Polish interventional cardiological centers, conducted from January 2014 until December 2021.

Aims: We aimed to determine the efficacy and safety of Impella using real-world data from IMPELLA-PL and compare these with other registries.

Safety and Efficacy of Orbital Atherectomy in the All-Comer Population: Mid-Term Results of the Lower Silesian Orbital Atherectomy Registry (LOAR).

Background: Coronary calcifications represent a challenging subset for the interventional cardiologist performing percutaneous coronary intervention (PCI) and are well-established risk factors for adverse outcomes. Adequate plaque modification prior to stent implantation is critical to achieve an optimal outcome following PCI. Recently, a novel orbital atherectomy device has been introduced into clinical practice to modify calcified plaques.

Bifurcation left main stenting with or without intracoronary imaging: Outcomes from the EBC MAIN trial.

Background: The impact of intracoronary imaging on outcomes, after provisional versus dual-stenting for bifurcation left main (LM) lesions, is unknown.

Objectives: We investigated the effect of intracoronary imaging in the EBC MAIN trial (European Bifurcation Club LM Coronary Stent study).

Methods: Four hundred and sixty-seven patients were randomized to dual-stenting or a stepwise provisional strategy.

Safety and efficacy of a novel calcified plaque modification technique - Shockwave Intravascular Lithotripsy - in patients with coronary artery disease: Mid-term outcomes.

Background: Coronary interventions in calcified lesions are associated with a higher rate of adverse clinical events. Initial aggressive plaque modification along with post-implantation optimization is pivotal for achieving a favorable outcome of percutaneous coronary intervention (PCI). Recently, the Shockwave C2 Intravascular Lithotripsy (S-IVL) System, a novel acoustic wave-based device designed to modify calcified plaque, has been introduced into clinical practice.

Mid-term safety and efficacy of magnesium bioresorbable vascular scaffolds - magmaris in diabetic population. 2-Years outcome in acute coronary syndrome cohort.

Background: Diabetes type 2 is one of the strongest risk factors affecting coronary artery disease (CAD) and is also a marker of poor short and long-term prognosis in subjects with acute coronary syndrome (ACS) treated with percutaneous coronary intervention (PCI) with subsequent drug-eluting stent (DES) implantation. Chronic local vascular inflammation along with endothelial dysfunction is postulated to be the pathophysiological background of unfavorable results. The second generation of metallic magnesium BRS -Magmaris (Biotronik, Berlin, Germany) had been introduced to clinical practice to overcome these limitations.

Comparison of Orbital Atherectomy and Rotational Atherectomy in Calcified Left Main Disease: Short-Term Outcomes.

Background: Coronary calcifications, particularly in left main disease (LMD), are independently associated with adverse outcomes of percutaneous coronary intervention (PCI). Adequate lesion preparation is pivotal to achieve favorable short- and long-term outcomes. Rotational atherectomy devices have been used in contemporary practice to obtain adequate preparation of the calcified lesions.
