Aims: We hypothesize that miRs are key players in the dynamics of the hypertrophy phenotype in aortic stenosis (AS) patients. In our study, we aimed to identify the transcriptional patterns (protein-coding transcripts and miRs) from myocardial sample biopsies that could be associated with the absence of left ventricular (LV) mass regression after aortic valve replacement (AVR) in patients with severe AS and LV hypertrophy.
Methods And Results: We prospectively included 40 patients with severe AS, LV hypertrophy, and preserved ejection fraction undergoing AVR.
: Coronary artery calcification is a predictor of adverse outcomes after percutaneous coronary intervention (PCI). Intravascular lithotripsy (IVL) is a promising tool for the treatment of calcified lesions. The aim of this study was to assess the effectiveness and safety of IVL.

Significant coronary artery disease (CAD) is a frequent finding in patients with severe aortic stenosis undergoing transcatheter aortic valve implantation (TAVI), and the management of these two conditions becomes of particular importance with the extension of the procedure to younger and lower-risk patients. Yet, the preprocedural diagnostic evaluation and the indications for treatment of significant CAD in TAVI candidates remain a matter of debate. In this clinical consensus statement, a group of experts from the European Association of Percutaneous Cardiovascular Interventions (EAPCI) in collaboration with the European Society of Cardiology (ESC) Working Group on Cardiovascular Surgery aims to review the available evidence on the topic and proposes a rationale for the diagnostic evaluation and indications for percutaneous revascularisation of CAD in patients with severe aortic stenosis undergoing transcatheter treatment.

We aimed to (1) develop AI models for CAG segmentation and (2) assess the results using similarity scores and a set of criteria defined by expert physicians.
Methods: Patients undergoing CAG were randomly selected in a retrospective study at a single center.
Background Atrial fibrillation (AF) is a major risk factor for mortality. The prevalence, clinical correlates, and prognostic impact of AF in Takotsubo syndrome (TTS) have not yet been investigated in a large patient cohort. This study aimed to investigate the prevalence, clinical correlates, and prognostic impact of AF in patients with TTS.

Methods: This was a single-center retrospective study including consecutive patients who underwent coronary angiography after cardiac arrest.
Results: A total of 117 patients (63 ± 13 years, 77% men) were included.
Aims: Acute pulmonary disorders are known physical triggers of takotsubo syndrome (TTS). This study aimed to investigate prevalence of acute pulmonary triggers in patients with TTS and their impact on outcomes.
Methods And Results: Patients with TTS were enrolled from the International Takotsubo Registry and screened for triggering factors and comorbidities.
Introduction: The Portuguese National Registry of Transcatheter Aortic Valve Implantation records prospectively the characteristics and outcomes of transcatheter aortic valve implantation (TAVI) procedures in Portugal.
Objectives: To assess the 30-day and one-year outcomes of TAVI procedures in Portugal.
Methods: We compared TAVI results according to the principal access used (transfemoral (TF) vs.

Introduction: Patient selection for percutaneous coronary intervention (PCI) in chronic total occlusions (CTOs) is crucial to procedural success. Our aim was to identify independent predictors of success in CTO PCI in order to create an accurate score.
Methods: In a single-center observational registry of CTO PCI, demographic and clinical data and anatomical characteristics of coronary lesions were recorded.
Aims: Takotsubo syndrome (TTS) is an acute heart failure syndrome, which shares many features with acute coronary syndrome (ACS). Although TTS was initially described with angiographically normal coronary arteries, smaller studies recently indicated a potential coexistence of coronary artery disease (CAD) in TTS patients. This study aimed to determine the coexistence, features, and prognostic role of CAD in a large cohort of patients with TTS.
View Article and Find Full Text PDFBackground: Takotsubo syndrome (TTS) occurs predominantly in post-menopausal women but is also found in younger patients.
Objectives: This study aimed to investigate age-related differences in TTS.
Methods: Patients diagnosed with TTS and enrolled in the International Takotsubo Registry between January 2011 and February 2017 were included in this analysis and were stratified by age (younger: ≤50 years, middle-age: 51 to 74 years, elderly: ≥75 years).
Objective: Takotsubo syndrome (TTS) is characterized by acute left ventricular dysfunction, which can contribute to intraventricular thrombus and embolism. Still, prevalence and clinical impact of thrombus formation and embolic events on outcome of TTS patients remain unclear. This study aimed to investigate clinical features and outcomes of patients with and without intraventricular thrombus or embolism.

We aimed to assess the diagnostic performance of iFR and its impact on the decision to use fractional flow reserve (FFR) and on procedural characteristics.
Methods: In this single-center registry of patients undergoing functional assessment of coronary lesions, FFR was used as a reference for assessing the diagnostic performance of iFR.
Acute aortic dissection is the most common acute aortic syndrome. It is more prevalent in males and in the elderly, and has a high mortality. Hypertension is the main risk factor.
View Article and Find Full Text PDFIntroduction: Patients referred for percutaneous transcatheter mitral valve repair using the MitraClip system frequently have atrial fibrillation, which imposes additional challenges due to the need for oral anticoagulation. Left atrial appendage occlusion is currently regarded as a non-inferior alternative to anticoagulation in patients with non-valvular atrial fibrillation and both high thromboembolic and bleeding risk. Considering that both MitraClip implantation and left atrial appendage occlusion are percutaneous techniques that require transseptal puncture, it is technically attractive to consider their concomitant use.
