Englisch: coronary sinus. 1 Definition. Der Sinus coronarius bzw. Koronarvenensinus ist ein Zusammenfluss mehrerer Herzvenen, der venöses Blut in den rechten Vorhof leitet. 2 Anatomie. Der Sinus coronarius liegt auf der Rückfläche (Facies posterior) des Herzens. Er verläuft quer zur Herzachse im Sulcus zwischen dem linken Vorhof und dem

Recently, the coronary sinus reducer (CSR) has been introduced in clinical practice as a new device-based treatment for patients with refractory angina (18, 19). Implantation of the CSR is the percutaneous equivalent of surgical CS narrowing as described by Beck et al. (20, 21) and shows promise as treatment for refractory angina.

The coronary sinus is a collection of veins joined together to form a large vessel that collects blood from the heart muscle (myocardium). It delivers less-oxygenated blood to the right atrium, as do the superior and inferior venae cavae. It is present in all mammals, including humans. Anomalous right coronary artery originated from left coronary sinus with interarterial course: evaluation of the proximal segment on multidetector row computed tomography with clinical correlation. J Comput Assist Tomogr 2009;33(5):755–762. Crossref, Medline, Google Scholar; 11 Zhang LJ, Wu SY, Huang W, Zhou CS, Lu GM. Injuries to the coronary sinus have occurred with a wide variety of instruments, such as guidewires, angioplasty catheters, balloon inflation, and by surgeons directly placing coronary sinus catheters. 3,4 In addition to 2-D imaging, real-time 3-D echocardiography has been used to guide a variety of catheter-based cardiac interventions including atrial septal occlusion, mitral balloon The coronary sinus angiogram 1 year before at the first CRT-pacemaker implant showed a large middle cardiac vein with collateral-branches to the postero-lateral area.

An unroofed coronary sinus, a.k.a. coronary sinus type ASD, is a rare variant of atrial septal defect (ASD).The atrial wall between the coronary sinus and left atrium is either partially or completely absent, resulting in a right-to-left shunt. It is associated with persistent left-sided SVC and heterotaxy syndromes.

The coronary sinus is not the only vessel that delivers deoxygenated blood to the heart; the superior venae cavae and inferior venae cavae are other large vessels that do the same. The coronary sinus courses along the posterior wall of the left atrium into the left atrioventricular groove. It normally drains into the right atrium. The ostium of the coronary sinus is partially covered by the Thebesian valve.

At LV lead replacement, a Medtronic 4193 lead, inserted over the guide wire, was placed in a large collateral branch from the middle cardiac vein towards the postero-lateral region.

Aiello, Flávia C. N. Ferreira, Mauricio I. Scanavacca, Robert H. Anderson, André D’Avila The coronary sinus was cannulated without significant complications using transesophageal echocardiography in 10 of 11 patients (mean, 10.5 minutes). Percutaneous cannulation of the coronary sinus can be accomplished in a safe and efficient manner using transesophageal echocardiography without the need for fluoroscopy.

Coronary Sinus Activation Sequence. CS activation sequence has frequently been suggested as a useful way to determine the chamber of interest; however, this is not without limitations. Whereas in RA flutter the CS is frequently activated from proximal to distal, this is not always true, particularly with AFL localized to the superior RA.

It is characterized by the absence of at least a portion of the common wall that separates the coronary sinus and left atrium. Englisch: coronary sinus. 1 Definition. Der Sinus coronarius bzw.

METHODS: We inserted a catheter into the coronary sinus under direct vision via a right atriotomy after completion of open heart operation in eight patients. The pressure waveforms of coronary sinus and central venous line, as well as the electrocardiogram (EKG), were recorded simultaneously after the patient was stable and weaned from the cardiopulmonary bypass.

cerebral sinus one of the ventricles of the brain. In unroofed coronary sinus there is a variably sized communication between the two structures (Figure 24.1). In partial unroofing, a single or several small orifices are seen. In complete unroofing, there is total absence of the tissue separating the left atrium and coronary sinus. Coronary sinus definition, a large venous channel in the heart wall that receives blood via the coronary veins and empties into the right atrium.
