BACKGROUND: The hemodynamics involved in the relationship between absolute coronary blood flow (ABF) volume and myocardial resistance (MR) are complex, and the effect of percutaneous coronary intervention (PCI) on their changes remains unclear. The aim of this study was to investigate the differences in hyperemic ABF and MR before and after elective PCI using a thermodilution method. METHODS AND RESULTS: We investigated 28 vessels (right coronary artery, 9; left anterior descending coronary artery, 18; left circumflex coronary artery, 1) from 28 patients with stable angina pectoris undergoing elective PCI...

BACKGROUND: Non-compaction cardiomyopathy (NCCM) is characterized by prominent trabeculations, deep intertrabecular recesses, and a thick non-compacted endocardial myocardium. Prevalence in the general population remains unclear, but echocardiography series report 0.05%. During fetal development muscle fibers and trabeculae should compact into a solid myocardium and when this fails, NCCM occurs. The condition is genetic, even though acquired forms have been described. Worsening myocardial dysfunction may lead to heart failure and/or arrhythmias...

Donor site morbidity is the most common limitation of the deep circumflex iliac artery (DCIA) flap, so the purpose of this paper is to describe a new, minimally-invasive, approach to its harvest using virtual surgical planning and CAD/CAM technology to reduce functional and aesthetic morbidity at the donor site. Virtual surgical planning was based on preoperative computed tomographic data. A newly-designed surgical guide made using CAD/CAM technology was used to transfer the virtual surgical plan to the site of operation...

A previously healthy 61-year-old man presented to the emergency department with chest pain and dyspnoea for 6 hours. Examination revealed distress with an apical pansystolic murmur. Initial electrocardiogram showed sinus tachycardia and ST elevation in leads II, III, and aVF compatible with an inferior ST-elevation myocardial infarction. Point-of-care echocardiography in the emergency department showed a flail anterior mitral leaflet and severe mitral regurgitation, leading to a provisional diagnosis of papillary muscle rupture...

Aims: Total occlusion (TO) of the culprit artery usually presents with ST-elevation myocardial infarction. A subset of patients with TO present as non-ST segment elevation myocardial infarction (NSTEMI) without classic ST-elevation on the electrocardiogram. This may lead to delay in identification of these patients and further management. We performed a meta-analysis to estimate the difference in outcomes between totally occluded and non-occluded culprit arteries in patients with NSTEMI...

BACKGROUND/OBJECTIVES: Complex extremity trauma commonly involves both soft tissue and vascular injuries. Traditional two-stage surgical repair may delay rehabilitation and functional recovery, as well as increase the risk of infections. We report a single-stage reconstructive surgical method that repairs soft tissue defects and vascular injuries with flow-through free flaps to improve functional outcomes. METHODS: Between March 2010 and December 2016 in our hospital, 5 patients with severe upper extremity trauma received single-stage reconstructive surgery, in which a flow-through anterolateral thigh free flap was applied to repair soft tissue defects and vascular injuries simultaneously...

Acute occlusion of the left circumflex coronary artery - in the »blind spot« of the ECG? Acute coronary artery occlusion should be treated with urgent revascularization. ECG is important in the triage of patients with acute coronary syndrome. ST deviation depends on the relation between the location of the transmural ischemia and the positive poles of the 12 ECG leads. In acute occlusion of the left circumflex artery, ST elevation in two contiguous leads is not always present. Instead, isolated ST depression in leads V1-V3 may be present and represents a »STEMI-equivalent« pattern...

A 54-year-old male developed a left ventricular pseudoaneurysm (Ps) along the lateral wall of the left ventricle (LV), which was diagnosed incidentally by two-dimensional transthoracic echocardiography (2DTTE) 6 months after an acute myocardial infarction. Color flow imaging (CFI) showed blood flow from the LV into the aneurysmal cavity and invasive coronary angiography revealed sub-occlusion of the circumflex artery. A complementary study using cardiovascular magnetic resonance (CMR) confirmed a dilated left ventricle with depressed ejection fraction, thin dyskinetic anterolateral and inferolateral walls, a Ps adjacent to the lateral wall of the LV contained by the pericardium and blood passing in and out through a small defect in the LV mid-anterolateral wall...

BACKGROUND: The diameters of the coronary arteries have been suggested to be a potential predictor of coronary artery disease (CAD). However, whether the diameters of the coronary arteries are associated with the coronary lesion severity on angiography has not been determined. METHODS: One hundred sixty-seven consecutive adult patients (109 men and 58 women) aged 31-84 years who underwent coronary angiography for suspected or known CAD were enrolled. The known catheter tip diameter was used as the calibration to measure the diameters of coronary arteries, and the severity of coronary lesions was evaluated with the vessel score and Gensini score...
