Coronary artery perforation (CAP) is a rare but feared complication of percutaneous coronary intervention. With the advent of new devices and technologies, interventionalists attempt more complex lesions, including more calcified or tortuous vessels and chronic total occlusions, which increases the incidence of CAP. A short literature review, in addition to four cases of CAP, is presented in this report.

An isolated congenital left ventricular diverticulum, which is characterized by the local failure of the ventricular muscle during embryologic development, is a rare cardiac abnormality that may be found in isolated form or in the accompaniment of other cardiac abnormalities. Clinically, it has been reported to follow an asymptomatic course in the majority of cases; however, it may cause heart failure, arrhythmia, or chest pain in some patients.

Aims: Recurrent pregnancy loss (RPL) is usually defined by two or more consecutive clinical miscarriages, which causes psychological trauma for couples. In this study, we aimed to investigate the predictive role of Fibrinogen to albumin ratio (FAR) in patients with RPL. Methods: Pregnant women in their first trimester of pregnancy were included in the study and divided in to two groups as RPL patients (n:44) and patients with no previous recurrent miscarriage (n:60) as control group. Demographical parameters and routine blood parameters (fibrinogen, D-dimer, fibrinogen to albumin ratio (FAR), neutrophil to lymphocyte ratio (NLR), platelet count, main platelet volume (MPV), and red cell distribution width (RDW) values) were compared between the RPL group and the control group. Results: The groups were determined to be statistically different in regards to gravidity and parity (p<0.05). The difference between the groups was statistically different in regards to fibrinogen (mg/dl), albumin (g/dl), FAR (%), NLR (%), RDW-coefficient of variation (CV) (%), RDW-standard deviation (SD) (fL), and platelet counts (10-3/ uL). However, MPV (fL) and D-dimer (ug/L) levels were similar in both groups. The receiver operating characteristic (ROC) curve analysis revealed that the NLR levels were 84.1% sensitive and 75% specific with a cut-off value of 4.27 and the FAR levels were 79.5% sensitive and 88.3% specific with a cut-off value of 105.69 for predicting RPL. Conclusion: Our results indicate that the FAR and NLR levels seem to be effective parameters for predicting RPL with high sensitivity and specificity.
