AIM: Inflammation plays an important role in development of coronary collateral circulation (CCC). The aim of this study is to determine whether the inflammation-related miRNA miR-155 and the inflammation marker VCAM-1 could be a biomarker for CCC. PATIENTS & METHODS: We measured levels of plasma VCAM-1 and miR-155 in patients with CCC according to Rentrop grade by ELISA or real-time polymerase chain reaction, respectively (n = 112). RESULTS: Plasma miR-155 was negatively correlated with VCAM-1 in the poor CCC group and with Rentrop grade in all patients with CCC...

BACKGROUND AND OBJECTIVES: Coronary collateral circulation (CCC) has been attributed as inborn bypass mechanisms supporting ischemic myocardium. Various factors have been postulated in CCC. Whole blood viscosity (WBV) has been an underappreciated entity despite close relationships between multiple cardiovascular diseases. WBV can be calculated with a validated equation from hematocrit and total plasma protein levels for a low and high shear rate. On the grounds, we aimed to evaluate the association between WBV and CCC in patients with chronic total occlusion...

AIMS: Septal surfing and distal tip injections are two techniques used for septal crossing in retrograde chronic total occlusion (CTO) percutaneous coronary interventions (PCI). We examined for the first time the safety and feasibility of the septal surfing technique. METHODS AND RESULTS: Among 470 consecutive CTO PCIs performed between 01/2010 and 12/2015, 240 (51%) involved a retrograde attempt. In the septal crossing subgroup, we evaluated if the Werner collateral channel (CC) classification, CTO location, tortuosity, and number of large septal CCs influenced retrograde crossing success, time, perforation...

The number of patients with arrhythmia and ischaemic heart diseases is increasing. Patients with pacemaker implantation sometimes have brachiocephalic vein occlusion, and several aetiologies have been reported. However, coronary artery bypass grafting using the internal thoracic arteries is not fully discussed in the literature. We present a case of failed percutaneous pacemaker implantation due to bilateral brachiocephalic vein occlusion 8 years after coronary artery bypass grafting using the bilateral internal thoracic arteries...

The data presented here support the research article "Association of serum mimecan with angiographic coronary collateralization in patients with stable coronary artery disease and chronic total occlusion" (Shen et al., 2016) [1] where elevated circulating mimecan levels reflected poor angiographic coronary collateralization in such patients. The data included in this article are composed by one figure and consist of (1) validation of serum mimecan measurement by assessing inter- and intra-assay variability in 45 samples; (2) findings on the relation of clinical and angiographic characteristics and biochemical parameters to coronary collateralization in 559 patients; (3) the diagnostic value of serum mimecan for poor collateralization, which was derived from plotting receiver-operating characteristic curves and logistic regression analysis...

AIMS: During transradial coronary catheterization the radial artery is functionally occluded and hand perfusion depends on the collateral circulation. Nexfin is a simple, non-invasive technique to measure digital arterial pressure and could serve to quantify the palmar collateral circulation. Potentially, inter-individual differences in the extent of collateralization are related to perfusion and function after transradial intervention. METHODS AND RESULTS: In total 85 adults were included (18 healthy volunteers; 67 patients who underwent transradial catheterization)...

BACKGROUND: In obstructive coronary artery disease (CAD), coronary collateral arteries serve as alternative conduits for blood flow to the myocardial tissue supplied by the obstructed vessel(s). Therefore, they are a "natural coronary arterial bypass" to the region supplied by the obstructed vessels. This study aims to determine the influence of demographic and morphologic coronary arterial factors on coronary collateral development in coronary arterial obstruction. MATERIALS AND METHODS: The study group was selected from the coronary angiographic records of 2029 consecutive patients (mean age: 59 ± 12 years)...

Angiogenesis and arteriogenesis have a crucial role in the formation of coronary collateral vessels. It has been shown that endocan and vascular cell adhesion molecule-1 (VCAM-1) are potential angiogenetic factors. We investigated the relationship between serum endocan levels and grade of coronary collaterals, and also the correlation of endocan levels with serum VCAM-1 levels. Patients with stable angina and at least one total coronary occlusion at invasive coronary angiography were included in our study. Collateral degree was graded according to Rentrop and Cohen's classification...

ALCAPA syndrome (anomalous origin of the left coronary artery from the pulmonary artery) is a rare disease but lethal with clinical expression from myocardial infarction, congestive heart failure to death during early infancy and unusual survival to adulthood. We report a 73-year-old woman with ALCAPA who presented with exertional dyspnea (NYHA functional class II) over past 2 years. Physical examination revealed soft S, long mid diastolic rumbling murmur and apical pan-systolic murmur. Electrocardiography displayed biatrial enlargement and poor R progression and normal sinus rhythm...
