We report a successful unroofing of the coronary sinus via a unique technique. Our patient was diagnosed with single ventricle morphology. Pulmonary artery banding and bidirectional cavopulmonary shunt were performed at 1 and 6 months old, respectively. Ordinary univentricular repair strategy was performed; extracardiac total cavopulmonary connection was achieved at 18 months old. Catheterization performed 1 year after the Fontan procedure revealed the coronary sinus orifice atresia, diffuse coronary artery stenosis, and sinusoid formation of the coronary system...

BACKGROUND: Dual RV has been proposed as an alternative for patients with heart failure undergoing cardiac resynchronization therapy (CRT) with a failure to deliver a coronary sinus (CS) lead. Only short-term haemodynamic and echocardiographic results of Dual RV are available. We aimed to assess the long-term results of Dual-site right ventricular pacing (Dual RV) and its impact on survival. METHODS: Multicentre retrospective assessment of all CRT implants during a 12-year period...

REVIEW
Jordan S Leyton-Mange, Theofanie Mela
Cardiac resynchronization therapy has emerged as the gold standard for heart failure patients with left ventricular systolic dysfunction and electrical dyssynchrony from an intrinsic intraventricular conduction delay or right ventricular pacing. However, the limits imposed by the coronary sinus venous anatomy restrict the applicability of the technology for many potential recipients. Furthermore, conventional resynchronization, by virtue of utilizing a single site of epicardial origin for left ventricular activation, is non-physiological...

INTRODUCTION: The electrophysiologic basis for characteristic rate-dependent, constant-late-coupled (390+54 msec) premature ventricular beats (PVBs) present 4-5 days following coronary artery occlusion were examined in 108 anesthetized dogs. METHODS AND RESULTS: Fractionated/double potentials were observed in injured zone bipolar and composite electrograms at prolonged sinus cycle lengths (1296 ± 396 msec). At shorter cycle lengths, conduction of the delayed potential decremented, separating from the initial electrogram by a progressively prolonged isoelectric interval...

Although transcatheter arrhythmia ablation (TCA) has been performed in children for over two decades, guidelines for routine use of post-ablation transthoracic echocardiography (TTE) are absent. We sought to determine the efficacy of TTE after apparently uneventful TCA procedures in detecting adverse findings and identify predisposing factors. A retrospective review of clinical and procedural data on patients who underwent TCA for supraventricular arrhythmias from 2000 to 2015 was performed. Pre- and post-ablation TTE data were reviewed...

BACKGROUND: Unroofed coronary sinus syndrome (URCSS) is a spectrum of cardiac anomalies in which part (partial type) or the entire common wall (complete type) between the coronary sinus (CS) and left atrium is absent. It is commonly associated with a persistent left superior vena cava (PLSVC). The PLSVC can even anomalously connect to the left atrium in complete type anomaly. URCSS has been reported to be associated with delayed diagnosis and life-threatening cerebral injury. The purpose of the present study was to review our experience with surgical correction of this often-concealed malformation and discuss methods for reducing diagnostic omission...

Anomalous aortic origin of a coronary artery is a rare congenital condition that has variable presentations from atypical chest pain to syncope and cardiac arrest. Commonly used myocardial perfusion imaging techniques, stress agents, and perfusion agents may have limited ability to detect inducible ischemia in this rare patient group. We herein describe a unique case of anomalous left main coronary artery from a common right coronary sinus ostium with a subpulmonic and intramyocardial course. This patient had multiple atypical chest pain presentations and multiple-negative pharmacologic single-photon emission-computed tomography stress tests performed...

INTRODUCTION: A association between partial anomalous pulmonary venous connection (PAPVC) and systemic venous anomalies has been described in the literature, but the true incidence is yet to be elucidated. At our institution, we sought to find the incidence of a persistent left superior vena cava (PLSVC) in patients undergoing an operation for PAPVC. METHODS: A retrospective review of all pediatric and adult patients with PAPVC who underwent surgical repair from February 2006 to February 2016...

Pregnancy results in substantial hemodynamic and prothrombotic changes that form the foundation for downstream vascular complications, both during pregnancy and in the postpartum period. In addition, several important risk factors, including older patient age, diabetes, and smoking, can increase the risk for vascular-related pregnancy complications. Because radiologists often play an important role in evaluation of the pregnant patient, understanding the pathophysiology of vascular-related complications in pregnancy and their imaging appearances is essential for diagnostic accuracy...

Persistent left superior vena cava (PLSVC) is a rare disorder which is asymptomatic and hence is usually discovered while performing interventions through the left subclavian vein. We present a case of a 78-year-old male who was undergoing elective placement of a permanent pacemaker for tachycardia - bradycardia syndrome with post-conversion pauses of up to nine seconds. After achieving access through the left subclavian vein the wire kept on going on the left side of the chest instead of crossing the midline to the right side...

Primary coronary sinus tumors are extremely rare. Herein, we present a case of a pregnant woman with a primary myxoma in the coronary sinus (CS), which was diagnosed by echocardiography and computed tomography. We reviewed the literature and found two other primary CS tumors. We summarized the gender, ages, symptoms, diagnostic methods, associated anomalies, treatments, histologic findings, and outcomes of the 3 cases. Dyspnea was a common symptom of all 3 patients. Diagnostic methods included echocardiography, computed tomography, magnetic resonance imaging, and coronary angiography...

The prognostic significance of atrial fibrillation (AF) on mortality in ST-segment elevation myocardial infarction (STEMI) patients is not clearly understood. To elucidate the clinical significance of AF on mortality for 1 year in STEMI patients, we retrospectively analyzed the Korea Acute Myocardial Infarction Registry (KAMIR) database, which spans January 2008 to September 2010 and includes 14,329 patients with acute myocardial infarction. We selected 5,556 patients with marked ECG rhythm (NSR, normal sinus rhythm or AF) on emergency room arrival, < 12 hours of symptom onset, and who underwent primary percutaneous coronary intervention (PCI) within 90 minutes of arriving at the hospital...

AIM: To investigate whether chromogranin A (CgA) is secreted from the heart into circulation. MATERIALS & METHODS: Porcine cardiac tissue was analyzed for the presence of CgA-derived glycopeptides using a global O-glycoproteomic strategy. Blood was sampled from the femoral vein, right atrium, coronary sinus and the left atrium from patients with predominantly atrial disease. The local concentration of proatrial natriuretic peptide and CgA was measured with immunoassays...

When medication management or percutaneous coronary intervention is not successful in patients with advanced ischemic heart disease, surgical revascularisation-predominantly coronary artery bypass grafting (CABG)-is considered the gold standard. However, CABG surgery can lead to ischemia/reperfusion injury, which is characterized by a strong inflammatory response. Interleukin (IL)-18, is a strong inflammatory mediator, that is released from cardiomyocytes and can be found in the systemic circulation of patients during and immediately after CABG surgery...
