There are plenty of data on morphology and lumen dimensions of diseased coronary arteries. However, information on normal coronary vessel anatomy is scarce. We provided computed tomography angiography-derived reference values of lumen dimensions in proximal and middle coronary segments in a healthy population with respect to gender and vessel dominance. Consecutive 2,849 computed tomography angiography examinations were reviewed to identify 201 subjects (77 men, patient age 50 ± 13 years) whose coronary arteries were free from any sign of atherosclerosis (calcium score 0, no detectable plaque)...

BACKGROUND: Coronary atherectomy, orbital or rotational, is frequently used for plaque modification in patients with heavily calcified lesions. Atherectomy can be associated with clinically significant bradyarrhythmias or transient atrioventricular block requiring temporary pacemaker insertion, mainly in lesions involving the right coronary artery or a dominant left circumflex artery. Bradyarrhythmias may be mediated by endogenous release of adenosine from red blood cell breakdown. Aminophylline, an adenosine antagonist, can prevent adenosine-mediated bradyarrhythmias...

BACKGROUND: Anteromedial thigh flaps are far less clinically appealing than their anterolateral counterparts, and are occasionally considered as an alternative to the anterolateral thigh flap. Herein, we report the study of soft-tissue defects reconstruction in the knee using a distally based anteromedial thigh flap pedicled on the rectus femoris branch of the descending branch of the lateral circumflex femoral artery. PATIENTS AND METHODS: Between July 2008 and September 2016, a distally based anteromedial thigh flap was used to reconstruct soft-tissue defects of the knee in 5 patients (3 males, 2 females; age range at surgery 4-55 years old)...

BACKGROUND: Progressive thinning and dilation of the LV due to ischemic heart failure (IHF) increases wall stress and myocardial oxygen consumption. Injectable biopolymers implanted in the myocardial wall have been used to increase wall thickness to reduce chamber volume, decrease wall stress, and improve cardiac function. We sought to evaluate the efficacy of a biopolymer (Algisyl-LVR) to prevent left ventricular (LV) remodeling in a swine model of IHF. METHODS: IHF was induced in 11 swine by occluding the marginal obtuse branches of the left circumflex artery...

BACKGROUND: We sought to investigate the impact of incomplete revascularization (IR) on long-term survival after isolated coronary artery bypass grafting (CABG). The possible interaction between IR and off-pump surgery was also explored. METHODS: A total of 13,701 patients with multivessel disease undergoing CABG were included in the analysis. All patients received left internal thoracic artery (LITA) to the left anterior descending artery (LAD) territory. IR was defined as at least one diseased arterial territory (right coronary artery [RCA] and/or circumflex [CX] artery) incompletely revascularized...

The anterolateral thigh flap (ALT) is a workhorse for a spectrum of reconstructive problems including head and neck defects. Its versatility as a chimeric flap employing a variety of soft tissues with a robust pedicle is useful for three-dimensional defects. The authors investigated the anatomical relationship between the vascular supply to the ALT and anterior femur. We studied 16 fresh cadaver limbs to identify the typical branching patterns to the femur off the descending branch of the lateral circumflex femoral artery...

The aim of this study is to assess the additive manufacture of morphometric models of healthy and diseased coronary arteries. Using a dissected porcine coronary artery, a model was developed with the use of computer aided engineering, with splines used to design arteries in health and disease. The model was altered to demonstrate four cases of stenosis displaying varying severity, based on published morphometric data available. Both an Objet Eden 250 printer and a Solidscape 3Z Pro printer were used in this analysis...

PURPOSE: Accurate determination of the bifurcation angle and correlation with plaque buildup may lead to the prediction of coronary artery disease (CAD). This work evaluates two techniques to measure bifurcation angles in 3D space using coronary computed tomography angiography (CCTA). MATERIALS AND METHODS: Nine phantoms were fabricated with different bifurcation angles ranging from 55.3° to 134.5°. General X-ray and CCTA were employed to acquire 2D and 3D images of the bifurcation phantoms, respectively...

PURPOSE OF REVIEW: To review recent literature on the subject of free tissue transfer options in paediatric head and neck surgery, with a particular emphasis on highlighting the advantages and disadvantages of different reconstructions in the paediatric patient. RECENT FINDINGS: Free tissue transfer in paediatric patients is predictable and applicable for a wide range of congenital and acquired defects in the head and neck. The free fibula flap is a mainstay of mandibular reconstruction and allows excellent implant-supported prosthodontic rehabilitation and growth potential at the recipient site with little or no donor site morbidity...

Although exercise testing has become a standard procedure before discharge for patients with acute coronary syndrome, a fatal accident during the test is extremely rare. A 60-year-old man was admitted for a non-ST-segment elevation myocardial infarction. A coronary angiogram showed stenosis at the distal lesion of the circumflex, and a balloon angioplasty was performed. His recovery was smooth, and a cardiopulmonary exercise test was performed 5 days after admission. At 2.5 metabolic equivalents, he suddenly went into cardiac arrest, and percutaneous cardiopulmonary support was initiated...

Background Procurement of the internal thoracic artery risks ipsilateral phrenic nerve injury and elevated hemidiaphragm. Anatomical variations increase the risk on the right side. Patients receiving left-sided in-situ right internal thoracic artery configurations appear to be at greatest risk. Methods From 2014 to 2016, 432 patients undergoing left-sided in-situ bilateral internal thoracic artery grafting were grouped according to right internal thoracic artery configuration: retroaortic via transverse sinus (77%) or ante-aortic (23%); targets were the circumflex and left anterior descending artery territories, respectively...

BACKGROUND: It is unclear why among patients with first acute myocardial infarction and an occluded culprit artery only some present ST segment elevation. In fact, there is no study that compares the angiographic area at risk and the collateral circulation in first NSTEMI vs STEMI patients. METHODS AND RESULTS: 205 patients admitted for myocardial infarction with occluded culprit artery were included, 132 STEMI and 73 NSTEMI. Demographic data, the area at risk determined by the BARI score and collateral supply by the Rentrop score from the 2 groups were compared...
