BACKGROUND: Retrograde perfusion into the coronary sinus is used to deliver cardioplegia. We developed an in-vivo porcine beating-heart model of self-myocardial retroperfusion (SMR) using the venous route to supply myocardial oxygenation and sought to assess hemodynamic and cardiac responses triggered by SMR before and after a prolonged occlusion of the LAD. METHODS: A bypass-line between the ascending aorta and the coronary sinus was made to perform a selective retrograde perfusion of the great cardiac vein with oxygenated blood (SMR)...

BACKGROUND: The communicating vein (CV) between the great cardiac vein and small cardiac venous systems passes between the aortic and pulmonary annulus and is located in close association with the left ventricular summit (summit CV). METHODS AND RESULTS: Thirty-one patients with idiopathic ventricular arrhythmias (VAs) underwent mapping of the left ventricular summit by using a 2F microcatheter introduced into the summit CV with coronary sinus venographic guidance...

Anomalous origin of left coronary artery from pulmonary artery (ALCAPA) accounts for 0.4% of the congenital heart diseases. Comprehensive 2D and 3D transesophageal echocardiographic imaging of a well-collateralized subset of ALCAPA is described. A nonstandard short-axis view of both aorta and pulmonary arteries showed the origin of left coronary artery from the posterior sinus of the pulmonary artery and right coronary artery in its usual position. Pulse-wave interrogation of the coronary arteries showed the direction of flow in opposite directions...

Left main coronary compression syndrome rarely occurs in patients with severe pulmonary hypertension. A 65-year-old woman with severe pulmonary hypertension due to an atrial septal defect suffered from angina on effort. Cardiac computed-tomography and coronary angiography revealed considerable stenosis of the left main coronary artery (LMA) caused by compression between the dilated main pulmonary artery trunk and the sinus of valsalva. Stenting of the LMA under intravascular ultrasound imaging was effective for the treatment of angina...

A 61-year-old male with a prosthetic St Jude aortic valve size 24 presented with heart failure symptoms and minimal-effort angina. Eleven months earlier, the patient had undergone cardiac surgery because of an aortic root dilatation and bicuspid aortic valve with severe regurgitation secondary to infectious endocarditis by Coxiela burnetii and coronary artery disease in the left circumflex coronary artery. Then, a prosthesis valve and a saphenous bypass graft to the left circumflex coronary artery were placed...

AIMS: Circulating levels of microRNAs (miRNAs) are emergent promising biomarkers for cardiovascular disease. Altered expression of miRNAs has been related to heart failure (HF) and cardiac remodelling. We measured the concentration gradients across the coronary circulation to assess their usefulness to diagnose HF of different aetiologies. METHODS AND RESULTS: Circulating miRNAs were measured in plasma samples simultaneously obtained from the aorta and the coronary venous sinus in patients with non-ischaemic HF (NICM-HF, n = 23) ischaemic HF (ICM-HF, n = 41), and in control patients (n = 11)...

AIMS: MicroRNAs (miRNAs) are transported on high-density lipoproteins (HDLs) and HDL-associated miRNAs are involved in intercellular communication. We explored HDL-associated miRNAs concentration gradients across the coronary circulation in stable and unstable coronary artery disease patients and whether changes in the transcoronary gradient were associated with changes in HDL composition and size. METHODS: Acute coronary syndrome (ACS, n=17) patients, those with stable coronary artery disease (stable CAD, n=19) and control subjects without CAD (n=6) were studied...

Cardiac variant of total anomalous pulmonary venous return is a rare entity, whereby all the pulmonary veins drain directly to the right atrium or coronary sinus. The effective left heart blood flow channels through a small stretched patent foramen ovale and can often be confused with a variant of cor triatriatum. Cor triatriatum is a rare congenital cardiac anomaly where pulmonary veins drain to a persistent chamber above the left atrium with a membrane separating these two. There persists either a small aperture directly from the true to the accessory left atrium or none at all...

The control of the central nervous system (CNS) over the cardiovascular system (CS) has been modeled using different techniques, such as fuzzy inductive reasoning, genetic fuzzy systems, neural networks, and nonlinear autoregressive techniques; the results obtained so far have been significant, but not solid enough to describe the control response of the CNS over the CS. In this research, support vector machines (SVMs) are used to predict the response of a branch of the CNS, specifically, the one that controls an important part of the cardiovascular system...

BACKGROUND: Ventricular arrhythmias (VAs) from the left ventricular outflow tract (LVOT) can have multiple exits exhibiting divergent ECG features. METHODS: In a series of 131 patients with VAs with LVOT origin, 10 patients presented with divergent QRS morphologies. Multisite endo- and epicardial mapping of different exit sites was performed. RESULTS: The earliest ventricular activity of 23 LVOT VAs in 10 patients was detected in the endocardium of the LV in 7 patients, the aortic sinuses of Valsalva (SoV) in 3 patients, the distal coronary sinus in 6 patients, the anterior interventricular vein in 3 patients, and the posterior right ventricular outflow tract (RVOT) in 4 patients...

BACKGROUND: Coronary artery anomalies (CAAs) are congenital variations of one or more of the coronary arteries and they are an uncommon but important cause of chest pain and, in some cases, sudden cardiac death. Anomalies of coronary arteries may be found incidentally in 0.3-1% of healthy individuals. The three types of coronary artery anomalies are anomalies of origin, anomalies of course and anomalies of termination. The purpose of our study was to estimate the frequency of CAAs in Canton Sarajevo, B&H, and to deteremine the prevalence of origin, course and termination anomalies of coronary arteries...

The article discusses the issue of searching for optimum oral anticoagulants to prevent thrombosis and embolism induced by heart disease both in patients with atrial fibrillation and sinus rhythm. A complex bidirectional relationship between atrial fibrillation and coronary atherosclerosis is considered along with possible mechanisms for development of myocardial infarction in patients with atrial fibrillation. The authors provided evidence-based data which can be used in selecting an anticoagulant for prevention of heart disease induced thrombosis and embolism taking into account both the efficacy and safety established in randomized clinical studies...

Aneurysm of the sinus of Valsalva, a rare cardiac condition, results from dilation of an aortic sinus. Sudden aneurysm rupture can trigger rapidly progressive heart failure. We discuss the case of a 57-year-old woman with situs ambiguus, isolated levocardia, and polysplenia who presented with acute-onset heart failure. Transesophageal echocardiograms revealed an aneurysm of the right coronary sinus of Valsalva that had ruptured into the right atrial cavity. The patient underwent successful surgical repair. To our knowledge, this is the first report of a sinus of Valsalva aneurysm in a patient with this combination of congenital abnormalities...

Persistent left superior vena cava (PLSVC) is an uncommon congenital anomaly. We report a case of implantation of cardiac resynchronization therapy - pacemaker (CRT-P) device in a 38-year-old lady with idiopathic dilated cardiomyopathy. After left axillary vein puncture, we faced an unexpected entry of left subclavian to PLSVC draining into the coronary sinus (CS). The target posterolateral vein which had been identified before seemed to have an acute angle at its entry into the CS. Hence, at this stage we were in a dilemma, whether to switch to the right side or to continue from the same side...

BACKGROUND: Left atrial scarring is recognised as a critical component in the maintenance of atrial fibrillation and is associated with the failure of interventional treatment. Diminished bipolar voltage (LV) has been proposed as a useful tool for left atrial scar quantification. We hypothesised that, due to its anatomic location, signals on the coronary sinus catheter might be used to predict the amount of left atrial low voltage. METHODS AND RESULTS: A total of 124 patients (42% women, average age 66 ± 9 years) were included...

Anomalous drainage of the right superior caval vein into the left atrium is a rare congenital anomaly that causes cyanosis and occult infection owing to right-to-left shunting. Transcatheter management of this anomaly is unique and rarely reported. We report a 32-year-old man with a history of brain abscess, who was diagnosed with an anomalous right superior caval vein draining to the left atrium; right upper pulmonary vein and right middle pulmonary vein draining into the inferior portion of the right superior caval vein; and a left superior caval vein draining into the right atrium through the coronary sinus without a bridging vein...

REVIEW
P Syamasundar Rao, Andrea D Harris
The purpose of this review is to discuss the management of atrial septal defects (ASD), paying particular attention to the most recent developments. There are four types of ASDs: ostium secundum, ostium primum, sinus venosus, and coronary sinus defects. The fifth type, patent foramen ovale-which is present in 25 to 30% of normal individuals and considered a normal variant, although it may be the seat of paradoxical embolism, particularly in adults-is not addressed in this review. The indication for closure of the ASDs, by and large, is the presence of right ventricular volume overload...

Background: Despite technological and scientific efforts, the recurrence rate of persistent atrial fibrillation (AF) remains high. Several studies have shown that in addition to pulmonary vein (PV) isolation other non-PV triggers, particularly left atrial appendage may be the source of initiation and maintenance of AF. There are few studies showing the role of left atrial appendage (LAA) isolation in order to obtain higher success rate in persistent AF patients. Objective: We analyzed the LAA volume, volume index and shape relative to the LA in patients with persistent AF undergoing AF ablation...
