In this issue, a mini focus and a EuroIntervention State of the Art on intracoronary optical coherence tomography with articles on the use of OCT guidance in left main PCI; stent expansion criteria and functional results of PCI in NSTEMI patients treated with OCT-guided PCI; identifying unknown stent types using OCT; improving OCT image quality in patients with kidney disease or unknown renal function; in valvular disease and heart failure: neo-commissure alignment in TAVI using the Portico device. In peripheral interventions: treatment of intermediate- and high-risk pulmonary embolisms with local thrombolysis using rheolytic thrombectomy. In stroke and hypertension: the importance of stroke aetiology and thrombus location in clinical outcomes of ischaemic stroke patients treated by thrombectomy; retrieval of embolised left atrial appendage closure occluders, and more...
