Article Synopsis
- The article reviews the 2023 activity report from the Interventional Cardiology Association of the Spanish Society of Cardiology, highlighting key trends in interventional cardiology practices in Spain.
- A survey involving 119 hospitals revealed a slight decrease in diagnostic studies but an increase in percutaneous coronary interventions (PCI), with a notable rise in the use of drug-coated balloons and techniques for plaque modification.
- The findings indicate a stabilization in coronary interventions while showcasing a growth in complex procedures, particularly for valvular and nonvalvular structural heart diseases, with primary PCI becoming the leading treatment for myocardial infarction.
Data regarding rotational atherectomy percutaneous coronary intervention (RA PCI) angioplasty in the left main (LM) coronary artery are scarce, and mostly outdated. We aimed to describe clinical outcomes of RA PCI in LM. Patients requiring RA in 8 European countries and 19 centers were prospectively and consecutively included in the European registry of Cardiac Care of Calcified and Complex patients registry.

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.
Background: The Watchman FLX is a device upgrade of the Watchman 2.5 that incorporates several design enhancements intended to simplify left atrial appendage occlusion (LAAO) and improve procedural outcomes. 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.

Using the Euro4C registry, an international prospective multicentric registry of RA PCI, we evaluated the influence of gender on clinical outcomes of RA PCI. Between October 2016 and July 2018, 966 patients were included.

Anemia may reflect subclinical blood losses that can be exacerbated after percutaneous coronary intervention . We sought to prospectively determine the contribution of anemia to the risk of bleeding in 448 consecutive patients aged 75 or more years, treated by percutaneous coronary interventions without concomitant indication for oral anticoagulation.

Whereas AA is a substrate for pro-inflammatory eicosanoids, the release of EPA from cell membranes generates anti-inflammatory lipid mediators, contributing to the infarct-limiting effect observed experimental models. Clinical data are lacking.

In fact, OCT is able to differentiate between neointimal proliferation and neoatherosclerosis within the stent. We report a rare case of occlusive neoatherosclerosis presenting beyond one year after a successful drug-eluting stent implantation.

Yet adoption of RA is hampered by several factors: amongst others, by the lack of a standardised protocol. This European expert consensus document stems from the awareness of the large heterogeneity in the protocols adopted to perform rotational atherectomy.

The aim of this pilot study was to assess the functional impact of a high (150 mg/day) maintenance dose of clopidogrel in patients undergoing elective percutaneous coronary intervention (PCI). This is a prospective, randomized, platelet function study which was performed in elective PCI patients assigned to treatment with either a 75 mg (n = 20) or 150 mg (n = 20) daily maintenance dose of clopidogrel for 30 days; afterwards, all patients resumed standard dosing.

Background: Type 2 diabetes mellitus patients have increased platelet reactivity compared with nondiabetic patients. Whether HPR assessed in T2DM while in their steady-state phase of dual antiplatelet therapy is associated with an increased risk of major adverse cardiovascular events (MACE) is unknown.
Background: Adenosine triphosphate (ATP) has effects similar to adenosine, including a very short half-life, with the advantage of a much lower cost. Our aim was to evaluate whether myocardial single photon emission computed tomography (SPECT) with ATP can predict the rate of hard events.
Methods And Results: We studied 299 patients (188 men; mean age, 64 +/- 10 years) with known or suspected coronary disease with thallium 201 SPECT during ATP infusion and at rest.
