    1. Idiopathic ventricular fibrillation or myocardial infarction? Impact of optical coherence tomography on therapeutic decisions

      Idiopathic ventricular fibrillation or myocardial infarction? Impact of optical coherence tomography on therapeutic decisions

      A female patient (47 years old) was referred from a district hospital for Implantable Cardioverter-Defibrillator (ICD) insertion as secondary prevention. Cardiac arrest occurred one week earlier in the course of ventricular fibrillation with an effective defibrillation. It was preceded by the chest pain. ECG showed elevation of ST-segment in inferior leads. Coronary angiography exam did not show stenosis of coronary vessels (Fig. 1A, 1B, 1C). Her medical history revealed mitral and tricuspid valve surgery related to insufficiency 10 years before. No risk factors of ischemic heart disease. While hospitalized she underwent echocardiography, which found akinesis of the basal inferior wall ...

    2. Thromboembolic or atherosclerotic? Optical coherence tomography in determining the cause of myocardial infarction with ST-segment elevation

      Thromboembolic or atherosclerotic? Optical coherence tomography in determining the cause of myocardial infarction with ST-segment elevation

      In the last years, due to its high image resolution, Optical Coherence Tomography (OCT) has been largely exploited in the assessment of atherosclerotic plaque features. The results obtained in the OCT imaging may determine the choice of optimal treatment technique [1,2]. A 55-year-old man with no history of any cardiovascular disease was admitted to the hospital with typical severe retrosternal pain. Acute myocardial infarction with ST-segment elevation (STEMI) was diagnosed. Immediate coronary angiography showed large thrombus causing subtotal occlusion in the medial and distal segments of the right coronary artery (RCA) with TIMI flow 2 and the occlusion of ...

    3. Myocardial infarction with non-obstructive coronary arteries (MINOCA) in young women: the key role of optical coherence tomography

      Myocardial infarction with non-obstructive coronary arteries (MINOCA) in young women: the key role of optical coherence tomography

      Optical coherence tomography (OCT) is an intracoronary imaging technique providing detailed morphological information on coronary lesions, improving an accurate diagnosis and the selection of an appropriate treatment strategy. A 26-year-old smoking female with no previous medical history and no risk factors for coronary heart disease was admitted to a local non-university hospital with an anterior STsegment elevation myocardial infarction (STEMI). On arrival, she has reported the chest pain lasting for several hours, and the ECG presented ST-segment elevation in all precordial leads. An echocardiogram showed regional motion abnormalities in the anterior wall of the left ventricle with significantly impaired ejection ...

    4. Optical coherence tomography improves the results of balloon pulmonary angioplasty in inoperable chronic thrombo-embolic pulmonary hypertension

      Optical coherence tomography improves the results of balloon pulmonary angioplasty in inoperable chronic thrombo-embolic pulmonary hypertension

      A 71-year-old woman with non-operable, peripheral type chronic thrombo-embolic pulmonary hypertension (CTEPH) and with World Health Organisation (WHO) class III dyspnoea was admitted to our department for balloon pulmonary angioplasty (BPA). Right heart catheterisation confirmed pulmonary hypertension (mean pulmonary artery pressure (mPAP) 37 mm Hg, mean right atrial pressure (mRAP) 6 mm Hg, pulmonary capillary wedge pressure (PCWP) 13 mm Hg, pulmonary vascular resistance (PVR) 214 dyn · s · cm–5 and cardiac Index (CI) 4.1 l/min · m2 ) and pulmonary scintigraphy showed multiple segmental perfusion defects (segments 1, 2, 8, 9 in the left lung and 2, 3, 4 ...

      Optical coherence tomography reveals the mechanisms of balloon pulmonary angioplasty in inoperable chronic thromboembolic pulmonary hypertension

      A 76-year-old female patient with chronic thrombo-embolic pulmonary hypertension (CTEPH) as a result of previous pulmonary embolism was admitted for balloon pulmonary angioplasty. Right heart catheterization showed mean pulmonary artery pressure of 61 mm Hg. Selective pulmonary angiography revealed subtotal occlusion of the A8 segmental branch of the left pulmonary
