Abstract Intracoronary physiology is routinely used in setting the indication for percutaneous coronary intervention (PCI) but seldom in assessing procedural results. This attitude is increasingly challenged by accumulated evidence demonstrating the value of post-PCI functional assessment in predicting long-term patient outcomes. Besides fractional flow reserve, a number of new indexes recently incorporated to clinical practice, including nonhyperemic pressure and functional angiographic indexes, provide new opportunities for the physiological assessment of PCI results. Largely, the benefit of these tools is derived from longitudinal analysis of the treated vessel, which allows precise identification of the vessel segment accounting for a suboptimal functional result and enabling operators to perform accurate PCI optimization. In this document the authors review available evidence supporting why physiological assessment should be extended to immediate post-PCI with the aim of improving patient outcomes. A step-by-step guide on how available physiological tools can be used for such purpose is provided.
Objectives The aim of this study was to evaluate post–percutaneous coronary intervention (PCI) outcomes in relation to pre-procedural glycated hemoglobin (HbA1c) levels from a large, contemporary cohort.
Objectives The aim of this study was to assess whether the effects of ticagrelor monotherapy after 3-month dual-antiplatelet therapy (DAPT) are consistent among patients presenting with ST-segment elevation myocardial infarction (STEMI), non–ST-segment elevation myocardial infarction, and unstable angina treated with drug-eluting stents.
Background: Symptom-to-balloon time (SBT) and door-to-balloon time (DBT) are both considered important metrics in patients undergoing primary percutaneous coronary intervention (pPCI) for ST-segment–elevation myocardial infarction (STEMI). We sought to assess the relationship of SBT and DBT with infarct size and microvascular obstruction (MVO) after pPCI.
Background: The clinical outcome after percutaneous coronary intervention (PCI) is affected by various clinical and procedural risk factors. We investigated the relative impact of clinical and procedural risks on clinical outcomes after PCI.
Background: We sought to evaluate the impact of patient selection for the STOPDAPT-2 trial (Short and Optimal Duration of Dual Antiplatelet Therapy After Everolimus-Eluting Cobalt-Chromium Stent-2) on clinical outcomes in a registry from a single center that participated in the STOPDAPT-2 trial.
Background: Stent implantation (SI) is more effective than balloon angioplasty for the treatment of coarctation of the aorta (CoA). Due to technical factors, balloon angioplasty is more commonly performed in small patients. We sought to evaluate outcomes of percutaneous adult sized SI for the treatment of CoA in small patients.
Abstract Constituting a significant proportion of lesions treated with transcatheter interventions in the coronary arteries, moderate-to-severe calcification portends lower procedural success rates, increased periprocedural major adverse events, and unfavorable long-term clinical outcomes compared with noncalcific plaques. Adapted from the lithotripsy technology for treatment of nephrolithiasis, intravascular lithotripsy is a new technique for treatment of severely calcific lesions that uses acoustic shock waves in a balloon-based system to induce fracture in the calcium deposits to facilitate luminal gain and stent expansion. Herein, we summarize the physics and characteristics of the currently available intravascular lithotripsy system (Shockwave Medical, Santa Clara, CA), the clinical data on intravascular lithotripsy use in the coronary arteries, and future directions for adoption of the technique in percutaneous coronary intervention.
Background: The optimal antithrombotic regimen after transcatheter aortic valve replacement remains unclear.
Background: As the use of left atrial appendage closure (LAAC) becomes more widespread, improvements in resource utilization and cost-effectiveness are necessary. Currently, there are limited data on same-day discharge (SDD) after LAAC. We aimed to evaluate the safety and feasibility of SDD versus non-SDD in patients with nonvalvular atrial fibrillation who underwent LAAC.
Background: The Bashir Endovascular Catheter (BEC) is a novel pharmaco-mechanical device designed to enhance thrombolysis by increasing the exposure of thrombus to endogenous and exogenous thrombolytics. The aim of this prospective, multicenter, single-arm study was to evaluate the feasibility and initial safety of the BEC in patients with acute intermediate-risk pulmonary embolism (PE).
Background: The conventional method of implanting balloon-expandable SAPIEN-3 (S3) valve results in a final 70:30 or 80:20 ratio of the valve in the aorta:left ventricular outflow tract with published rates of permanent pacemaker around 10%. We sought to evaluate whether higher implantation of S3 reduces conduction abnormalities including the need for permanent pacemaker.
Background: There has been increasing utilization of short-term mechanical circulatory support devices for a variety of clinical indications. Many patients have suboptimal iliofemoral access options or reasons why early mobilization is desirable. Axillary artery access is an option for these patients, but little is known about the utility of this approach to facilitate short-term use for circulatory support with microaxial pump devices.
Background: Previous studies have observed poorer outcomes in females with myocardial infarction, but older age and lower use of percutaneous coronary intervention in females are factors that potentially explain the worse outcome. This study sought to determine if female sex is an independent factor of ischemic and bleeding outcomes in non–ST-segment–elevation acute coronary syndrome treated with a systematic invasive approach.
Background: Interventional therapies aiming at excluding the left atrial appendage (LAA) from systemic circulation have been established as a valid alternative to oral anticoagulation in patients at high thromboembolic risk. However, their efficacy on stroke prophylaxis may be compromised owing to incomplete LAA closure. Additionally, the need for an alternative thromboembolic prevention may remain unmet in patients with contraindications to oral anticoagulation whose appendage anatomy is unsuitable for some conventional devices commercially available. We aimed at evaluating the feasibility of LAA closure with the novel Gore Cardioform Septal Occluder in patients with incomplete appendage ligation or anatomic features which do not meet the manufacturer’s requirements for Watchman deployment.
