Magnetic resonance cardiac vein imaging: relation to mitral valve annulus and left circumflex coronary artery.

摘要: Objectives To evaluate in vivo anatomical relationships between the coronary sinus–great cardiac vein (CS–GCV), mitral valve annulus (MVA), and left circumflex artery (LCX) with cardiovascular magnetic resonance. Background The CS–GCV has become an structure of interest because it provides a way access to heart for number interventional procedures. Previous reports demonstrate that postulated close proximity MVA does not always hold true patients, both autopsy specimens by computed tomography. Methods In 31 participants (24 volunteers 7 patients; 15 men; 42 ± 19 years), resonance was performed noninvasive evaluation sinus arteries using whole-heart imaging intravascular contrast agents. Three-dimensional reconstructions, standard orthogonal planes, unprocessed raw data were used assess anatomy its relation LCX along their entire course. Results located behind atrium all examined participants, at minimum distance 8.6 3.9 mm from MVA. 80% crossed inferiorly, had parallel course 26.2 23.0 mm, great variability location length. several long course, but other below discrete point. Conclusions coursed rather than majority These should be kept mind when referring patient procedures requiring CS–GCV, might provide important information selection candidates these
