Figure 9 Variations in Coronary Venous Anatomy
With the use of 64-slice multidetector row computed tomography, the prevalence of the PIV, PVLV, and LMV was assessed in 28 normal control patients, 38 patients with coronary artery disease (CAD), and 34 patients with a history of myocardial infarction. The LMV was less frequently identified in patients with a history of myocardial infarction as compared with CAD patients and control patients (27% vs. 61% and 71%, respectively). This may hamper left ventricular lead positioning in case of CRT. *p < 0.01. **p < 0.0001. Abbreviations as in Figure 5. Adapted from Van de Veire et al. (62).
