Background: Dimensions of the coronary sinus are important in the design of cannulation devices used in cardiac resynchronization therapy and percutaneous mitral valve annuloplasty. Gender and population variations may account for the failure rate of these procedures. Cardiac conditions requiring these procedures are common in black African populations. There are, however, hardly any studies on the regions of coronary sinus in these populations.

“…These data are consistent with that of Blendea et al, who performed a detailed analysis of CS anatomy in patients with CRT. 20 They found that 9% of patients did not have a lateral branch and that women had smaller diameter CS branches and shorter lateral branches compared to men. In spite of the anatomical differences in CS anatomy between men and women, the proportion of patients with successful LV lead placement in the mid-lateral wall was similar between men and women in the present study.…”

“…At each visit, clinical functional status was recorded and device interrogation was performed. Patients were followed in a multidisciplinary CRT clinic that includes providers from the elecported in patients undergoing CRT, 20 it remains unclear whether significant anatomical differences exist between men and women and, if so, whether this has an impact on LV lead placement and LV lead parameters. Thus, the aim of this study was to investigate potential gender difference in CS anatomy and LV lead parameters among patients undergoing CRT.…”

Background: Recent studies have suggested better outcomes from cardiac resynchronization therapy (CRT) in women. Gender differences in coronary sinus (CS) anatomy and left ventricular (LV) lead parameters in patients undergoing CRT, however, have not been well studied. Methods and Results:Two hundred and twenty-three consecutive patients, undergoing CRT at the University of California in San Diego Medical Center from 2003 to 2011 were included in this study. The location of the LV lead was assessed on coronary venography and chest X-ray recorded at the time of device implantation. Optimal LV lead position was defined as either mid-lateral or posterolateral LV wall. The relationship between LV lead position (optimal or non-optimal position) and LV lead parameters at completion of implant were compared between genders. No statistically significant gender differences were noted in baseline characteristics. LV lead implantation was successful in 217 patients (97.3%). Lateral or posterolateral CS branches were unavailable in more women than men (26.3% vs. 10.8%, P=0.011). Women had a higher LV lead pacing threshold than men (P=0.003) and gender was an independent risk factor of high LV lead pacing threshold (P=0.008). Conclusions:Women had an anatomical disadvantage for LV lead placement and had higher LV lead pacing threshold compared to men. Implanting physicians should be aware of gender differences during LV lead placement in order to maximize CRT benefits. (Circ J 2013; 77: 1424 -1429

“…Some centers perform a single venography image, however, two orthogonal views (RAO and LAO) are preferred for better visualization of 3 dimensional anatomy. A minority of centers perform rotational venography, which may provide more detailed information (Blendea, 2007). The location and takeoff of the ostium may vary considerably, can be distorted by right atrial enlargement or prior surgery.…”
