The Circle Of Life: Vieussens’ Arterial Ring

Di: Ava

The course of this collateral pathway seem to partially form a large, ring-shaped structure on all sides of the pulmonary outflow tract [1]. This structure is termed Vieussens’ ring, or the arterial circle of Vieussens, after its first description 300 years before by anatomic dissection [2,3]. We recommended coronary artery bypass grafting. The Vieussens’ artery is an anastomotic communication between the conus branch of the RCA and the LAD. Vieussens’ ring is so named because it circles around the great vessels in the form of a partial ring. The course of the artery can be best understood in 2 orthogonal views. In coronary artery disease, the presence of Vieussens‘ arterial ring (VAR), a ring-shaped anastomosis between the conus branch of the right coronary artery with the left anterior descending artery (LAD), will allow blood flow to return to the obstructed coronary system.

Vieussens’ Ring | Circulation

A 79-year-old woman presented with a systolic murmur and dyspnea on exertion. Transthoracic echocardiography and multidetector-row computed tomography revealed a giant aneurysm in an abnormal vessel known as Vieussens’ arterial ring (VAR). A pulmonary artery VAR fistula was also observed. Cardiac catheterization revealed a high pulmonary-to-systemic flow ratio

The Vieussens’ arterial ring (VAR) is a connection between the conus artery and the left anterior descending (LAD) coronary artery’s proximal right ventricular branch. VAR is present in about 48 percent of the population as an embryonic conotruncal ring remnant. This ring can be exploited as an alternative coronary artery revascularization route in patients where this ABSTRACT: The Vieussens’ arterial ring (VAR) is a rare coronary anomaly that may be associated with a pulmonary fistula, and has been linked to ischemia, myocardial infarction, heart failure, arrhythmias, and sudden death.

The arterial circle of Vieussens is a rare anatomical variant that can significantly impact cardiac function. This case report presents a 21-year-old patient diagnosed with classical Hodgkin lymphoma who experienced nonspecific right-sided chest tightness. During cardiovascular evaluation, we discovered abnormal flow patterns that were suggestive of a Vieussens’ arterial ring (VAR) is a coronary anomaly characterized by an abnormal connection between the conus branch of right Coronary artery (RCA) and any branch of left main coronary artery (LMCA). 1 In literature, there are case reports regarding VAR. Usually, VAR remains undetected and the patients with the anomaly usually do not present with any clinical Vieussens‘ ring is an embryologic remnant that acquires clinical significance as an intercoronary collateral vessel in advanced coronary artery disease. Its origin as a peritruncal structure early

Vieussens’ arterial rings can be subdivided into four groups. Only one case report of a Type Ib Vieussens’ ring has been identified on literature review, where the patient presented with a non-ST elevation myocardial infarction, unlike the atrial tachyarrhythmia in this case. Vieussens‘ arterial ring is a rare anatomic variant consisting of an anastomotic connection between the conus artery and branch vessels of the left coronary artery.

The preconal ring (circle #1), also known as Vieussens‘ arterial ring, comprises right pulmonary conus branches arising from the RCA or the aorta and left conus branches arising from the left main or proximal LAD arteries. The right anterior conal branch exists in 100% of cases and in 50% it may arise from the right aortic sinus.

The Vieussens’ arterial ring (VAR) is a rare coronary anomaly that may be associated with a pulmonary fistula, and has been linked to ischemia, myocardial infarction, heart failure, arrhythmias, and sudden death. We present the case of a 54-year-old man wh Vieussens’ arterial ring (VAR) provides a connection between the conus artery and the left anterior descending coronary artery’s proximal right ventricular branch (1). VAR has been reported to be present in 48% of the population as an embryonic conotruncal ring remnant (2). However, the VAR detection rates are low when imaging methods are

To our knowledge, clinical reports of coronary-pulmonary artery fistula (CPAF) associated with coronary artery aneurysm (CAA) and Vieussens’ arterial ring (VAR) are exceedingly rare, with limited documentation of related surgical treatments.

Schematic of Conotruncal Arterial Collateral Circulation An anatomic representation of the coronary anastomotic rings. The more commonly known Vieussens’ arterial ring (#1) travels anterior to the aorta to form a preconal ring connecting left and right coronary circulations.

In coronary artery disease, the presence of Vieussens’ arterial ring (VAR), a ring-shaped anastomosis between the conus branch of the right coronary artery with the left anterior descending artery (LAD), will allow blood flow to return to the obstructed coronary system. We have conducted a literature review, aiming to collect all the existing information about the In patients with coronary artery disease (CAD), collateral circulation aids in sustaining myocardial perfusion and cardiac function. The circle of Vieussens is a rare collateral pathway between the right coronary artery and the left anterior descending artery (LAD) that plays a significant role spec

„Vieussens‘ ring“ or „arterial circle of Vieussens“ is a crucial hetero-coronaric pathway, bridging proximal right coronary artery (RCA) and left anterior descending artery (LAD) when a hemodynamically stenosis is established in the either of the vessel. In detail such coronary collateral circulation is usually supplied by branches of the conus artery. We present Vieussens’ arterial ring is a rare congenital anomaly of coronary arteries, which was previously associated with collateral circulation in the event of occlusion or agenesis of LCA. This case indicates the association between presence of Vieussens’ arterial ring and MI with non-obstructive coronary arteries. Images in Intervention Shahbaz A.

In addition, a systematic review of the Vieussens‘ arterial ring, which is a ring-shaped anastomosis between the conus branch and the LAD, suggested anatomical classification [10].

Vieussens’ arterial ring (VAR) is widely described as a collateral pathway between the conus branch of the RCA and the proximal right ventricular branch of the LAD coronary artery. [1, 2] VAR does not form only due to CAD; it could also develop

The collateral pathway between the right and the left coronary circulation is the so-called Vieussens’ arterial ring (VAR) or the arterial circle of Vieussens [6]. It owes its name to the French philosopher, physician and anatomist, Raymond de Vieussens who first described it in 1706. TITLE: Collaterals of Life: Fistulous Communication of Vieussens’ Arterial Ring AUTHORS: Elba Palacios-Espinoza, Javier Figueroa-Tataje, Hugo Maximiliano-Nieva KEYWORDS: Vieussens’ Arterial Ring, Pulmonary Fistula, Coronary Artery Anomaly JOURNAL NAME: Case Reports in Clinical Medicine, Vol.12 No.9, September 1, 2023 ABSTRACT: The Vieussens’ arterial ring

We report a rare case of Vieussens’ arterial ring to main pulmonary artery fistula in patient with chest pain who underwent computed tomography (CT) coronary angiography. This case highlights a rare type of coronary-pulmonary artery fistula and role of CT angiography in detecting such anomalies which carry important hemodynamic implications. It is imperative to

ABSTRACT Introduction. In 1706, Raymond de Vieussens described a proximal inter-coronary pathway connecting the conus branch of the right coronary artery (RCA) with an infundibular branch of the left anterior descending artery (LAD) or directly with the proximal LAD. Later, in the 19 th century, this anatomical structure would be named in his honour “Vieussens’

The CTA further revealed a fistula originating from the Vieussens ring draining into the MPA, consistent with a diagnosis of PAF in association with arterial circle of Vieussens. The anterior mediastinal mass was also identified, consistent with biopsy-proven Hodgkin lymphoma.
