To explore the effectiveness and safety of the Expressman tapered extension catheter in the treatment of coronary artery chronic total occlusion (CTO).
A total of 228 patients with coronary CTO who used extension catheters during percutaneous coronary intervention (PCI) in Zhongshan Hospital, Fudan University from May 2021 to May 2023 were retrospectively selected. The patients were divided into 5F Expressman extension catheter group (5F group, n＝97) and 5-4F Expressman tapered extension catheter group (5-4F group, n＝131). The demographic characteristics, data related to interventional procedure and major adverse cardiovascular events (MACEs) during hospitalization were compared between the two groups.
There were no significant differences in age, gender, smoking history, PCI history, coronary artery bypass grafting (CABG) history, or previous myocardial infarction between the two groups. The most common lesion of CTO was the right coronary artery (65.4%), followed by the left anterior descending artery (26.3%). The median J-CTO score was 3(2, 3).The intubation depth of the 5-4F group was significantly higher than that of the 5F group ([43.9±18.3] mm vs [29.7±21.3] mm, P < 0.001). The incidence of intraoperative pressure damping in 5-4F group was significantly lower than that in 5F group (3.1% vs 9.3%, P＝0.045), and the success rate of device delivery in 5-4F group was significantly higher than that in 5F group (97.7% vs 90.7%, P＝0.019). No MACEs were observed during hospitalization in both groups.
The application of the Expressman tapered extension catheter in interventional therapy of CTO lesions can improve the success rate of device delivery and reduce the occurrence of pressure damping.
