Local Intracoronary Fibrinolysis with Distal Occlusion: A Series of Cases Using Marinade Technique.

No-reflow phenomenon is frequent in patients with ST-segment elevation myocardial infarction (STEMI) and has proven to be a strong predictor of mortality. Local fibrinolytic infusion with distal coronary occlusion (previously described as "marinade technique") can be useful in patients with acute myocardial infarction and intraluminal thrombus refractory to aspiration enabling the local effect of the drug, directly applied inside the thrombus, while protecting the microvasculature with prolonged inflation of a distal balloon. We present the early experience of four patients with inferior acute myocardial infarction and high thrombus burden successfully treated with marinade technique in one center.

Complex anatomy making it difficult for left atrial appendage closure.

Left atrial appendage closure is a useful technique for patients at high thromboembolic risk and contraindications for oral anticoagulation therapy. However, it can be challenging when anatomical difficulties are encountered. We present a unique case of atypical appendage uptake and how we completed the procedure.

Optical coherence tomography: from research to practice.

Optical coherence tomography (OCT) is a high-resolution imaging technique with great versatility of applications. In cardiology, OCT has remained hitherto as a research tool for characterization of vulnerable plaques and evaluation of neointimal healing after stenting. However, OCT is now successfully applied in different clinical scenarios, and the introduction of frequency domain analysis simplified its application to the point it can be considered a potential alternative to intravascular ultrasound for clinical decision-making in some cases. This article reviews the use of OCT for assessment of lesion severity, characterization of acute coronary syndromes, guidance of intracoronary stenting, and evaluation of long-term results.
