The most treated coronary arteries were the right coronary in 24 patients (60%) of Group I versus 20 patients (50%) of Group II (P=0.369), and the left circumflex in 16 patients (40%) of Group I versus 20 patients (50%) of Group II (P=0.369). None of the patients in both groups had left anterior descending or ramus intermedius artery lesions. Regarding the mitral valve lesions, mitral stenosis was found in 24 patients (60%) of Group I versus 16 patients (40%) of Group II (P=0.074), mitral regurgitation in 8 patients (20%) of Group I versus 4 patients (10%) of Group II (P=0.210), and mixed mitral lesions (stenosis + regurgitation) in 8 patients (20%) of Group I versus 20 patients (50%) of Group II (P=0.005). There was a statistically significant association between groups regarding mixed mitral valve lesions only. However, the association was not statistically significant regarding left circumflex artery lesions, right coronary artery lesions, mitral valve stenosis, and mitral valve regurgitation. The median time interval between PCI and mitral valve surgery in Group I was 93 days (IQR, 91-95) (Table 4).
