Evaluation of Success and Complications Scores for Chronic Total Occlusion Percutaneous Coronary Interventions: Insights from the Latin American Registry.

Chronic total occlusion (CTO) percutaneous coronary intervention is a complex procedure and is associated with considerable risk of complications. Several success and complication scores have been developed; however, data regarding their external validation in other populations such as Latin America are scarce. This study aimed to evaluate the accuracy of the main predictors of success and complications in a broad cohort of procedures in the Latin American (LATAM) CTO registry.

Coronary artery complications after left bundle branch area pacing: An increasingly reported issue in the era of physiologic pacing.

Coronary artery lesions related to pacemaker implantation are rare complications. With the increasing adoption of the technique of permanent transseptal pacing of the left bundle branch area pacing (LBBAP), an increase in the incidence of these complications may be expected. We report two cases of coronary lesions after permanent transeptal pacing of the LBBAP: the first with a small coronary artery fistula, and the second with an extrinsic coronary compression.

Overview of Percutaneous Coronary Interventions for Chronic Total Occlusions Treated at Brazilian Centers Participating in the LATAM CTO Registry.

Background: Major advances have been seen in techniques and devices for performing percutaneous coronary interventions (PCIs) for chronic total occlusions (CTOs), but there are limited real-world practice data from developing countries.

Objectives: To report clinical and angiographic characteristics, procedural aspects, and clinical outcomes of CTO PCI performed at dedicated centers in Brazil.

Methods: Included patients underwent CTO PCI at centers participating in the LATAM CTO Registry, a Latin American multicenter registry dedicated to prospective collection of these data.

Creation and Implementation of a Prospective and Multicentric Database of Patients with Acute Myocardial Infarction: RIAM.

Background: Multicenter registries representing the real world can be a significant source of information, but few studies exist describing the methodology to implement these tools.

Objective: To describe the process of implementing a database of ST-segment elevation acute myocardial infarction (STEMI) at a reference hospital, and the application of this process to other centers by means of an online platform.

Methods: In 2009, our institution implemented an Registry of Acute Myocardial Infarction (RIAM), with the prospective and consecutive inclusion of every patient admitted to the institution who received a diagnosis of STEMI.

Accuracy of dedicated risk scores in patients undergoing primary percutaneous coronary intervention in daily clinical practice.

Background: Comparisons between dedicated risk scores in patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (pPCI) in real-world clinical practice are scarce. The aim of this study was to assess the diagnostic performance of the Global Registry of Acute Coronary Events (GRACE), Primary Angioplasty in Myocardial Infarction (PAMI), Thrombolysis in Myocardial Infarction (TIMI), and Zwolle scores in STEMI patients undergoing pPCI in contemporary clinical practice.

Methods: This was a prospective cohort study of consecutive patients with STEMI undergoing pPCI between December 2009 and November 2010 in a high-volume tertiary referral centre.

Red versus white thrombi in patients with ST-elevation myocardial infarction undergoing primary percutaneous coronary intervention: clinical and angiographic outcomes.

Background: Aspiration thrombectomy is used in primary percutaneous coronary interventions, but the importance of thrombus constituency has been scarcely investigated. The objective of this study was to evaluate thrombus constituency and its association with clinical, laboratory, and angiographic findings in patients with ST-segment elevation myocardial infarction.

Methods: From April 2010 to May 2011, 562 patients with ST-segment elevation myocardial infarction undergoing primary percutaneous coronary interventions were considered for inclusion, and information on thrombi characteristics was available for 113 patients.

Intracoronary ultrasound-guided stenting improves outcomes: a meta-analysis of randomized trials.

Background: Intracoronary ultrasound (IVUS) has been used as an adjunctive method in order to optimize implantation of stents. However, the impact of this method in some outcomes is controversial.

Objective: To systematically review the impact of routine IVUS-guided coronary stent as compared to angiographic-guided, on clinical and angiographic outcomes.

Psychological characteristics of patients undergoing percutaneous coronary interventions.

Background: There is few data evaluating the prevalence and influence of adverse psychological characteristics on the prognosis of individuals submitted to percutaneous coronary interventions. No study has addressed this issue in Brazil.

Objective: To investigate the prevalence of depression, anxiety, psychological stress, and Type D personality and its association with cardiovascular events in patients undergoing percutaneous coronary interventions.

[Wellens syndrome].

The assessment of chest pain is a routine in emergency health services. Although this is a common complaint with a broad differential diagnosis. the major concern is the possibility of acute coronary syndrome (ACS).
