The year 2024 has witnessed substantial advancements in interventional cardiology, encompassing both coronary and structural interventions.In coronary field, trials have explored percutaneous innovations for coronary lesions, strategies for managing post‑infarction cardiogenic shock and non‑invasive approaches for guiding revascularization. The uploaded guidelines for chronic coronary syndromes emphasize individualized care, integrating modalities such as fractional flow reserve (FFR), intravascular ultrasound (IVUS), optical coherence tomography (OCT) and new teatments, including cochicine, GLP-1 receptor agonists and bempedoic acid.

Post-capillary hypertension resulting from mitral regurgitation is typically considered a contraindication for single lung transplantation due to heightened risks of primary graft dysfunction. This case report highlights a 66-year-old COPD patient with severe mitral regurgitation who was deemed ineligible for surgical mitral replacement. As an alternative, transcatheter mitral valve replacement was successfully performed, resulting in the normalization of pulmonary artery pressures.

A 53-year-old male individual with chronic severe mitral regurgitation presented with biventricular dysfunction, pulmonary hypertension, and atrial fibrillation. Echocardiography demonstrated a posterior leaflet prolapse with malcoaptation. Mitral valve repair and Maze procedure were performed, revealing absent chordae and direct connection from the anterolateral papillary muscle to the posterior leaflet, consistent with partial mitral arcade.

Objective: To develop a model for preoperatively predicting postcardiotomy cardiogenic shock (PCCS) in patients with poor left ventricular (LV) function undergoing cardiac surgery.
Methods: From the Society of Thoracic Surgeons Adult Cardiac Database, 11,493 patients with LV ejection fraction ≤35% underwent isolated on-pump surgery from 2018 through 2019, of whom 3428 experienced PCCS. In total, 68 preoperative clinical variables were considered in machine-learning algorithms trained and optimized using scikit-learn software.
Ischaemic stroke due to thrombus formation on the ventricular side of the mitral valve more than one year after MitraClip implantation: a case report.
Acta Cardiol
January 2025
Cardiology, AZ Groeninge, Kortrijk, Belgium.
Objectives: Edge-to-edge mitral valve repair with MitraClip leads to a differed flow pattern and a decreased flow velocity at the left ventricle apex. This combination may lead to initiation of thrombus formation, especially in patients with severely reduced ejection fraction. The prevalence and mechanism of left ventricular thrombus formation after MitraClip implantation is still unknown.
