Insights
The cut balloon technique (CBT) effectively seals coronary artery perforations. This method is safe and efficient, often requiring only one or two balloon fragments for embolization.
Area of Science:
- Interventional Cardiology
- Vascular Medicine
- Cardiovascular Interventions
Background:
- Iatrogenic distal coronary artery perforation is a serious complication during cardiac procedures.
- Limited data exist on using the cut balloon technique (CBT) for embolizing coronary perforations.
Purpose of the Study:
- To evaluate the safety and efficacy of the cut balloon technique (CBT) for treating distal coronary artery perforations.
- To assess in-hospital outcomes associated with CBT in this patient population.
Main Methods:
- A multicenter study included 26 patients with coronary perforations treated with CBT between 2017 and 2023.
- Collected data on clinical, angiographic, and procedural characteristics, as well as in-hospital outcomes.
Main Results:
- CBT successfully treated 25 distal coronary perforations and one septal perforation.
- Most perforations (40%) were in the left anterior descending artery.
- Favorable in-hospital outcomes were observed, with only 16% requiring pericardiocentesis and no emergency surgeries or cardiac deaths.
Conclusions:
- The cut balloon technique (CBT) is a safe, efficient, and easily implemented method for embolizing coronary perforations.
- One or two balloon fragments are often sufficient to seal perforations, potentially avoiding the need for specialized devices.
Background:
Iatrogenic distal coronary artery perforation can be a life-threatening complication. While there are different dedicated devices for the embolization of distal perforations, there are scarce data about the embolization using the fragmented balloon catheter, the so-called cut balloon technique (CBT).
Methods:
We included consecutive patients with distal coronary perforations treated with CBT in four cardiac centers between 2017 and 2023. Clinical, angiographic and procedural characteristics as well as in-hospital outcomes were recorded.
Results:
Twenty-six patients (68% men, mean age: 71 ± 10.6 years) with 25 distal coronary perforations and one septal collateral perforation were included. Eleven patients (42%) had elective percutaneous coronary intervention, while fifteen patients (58%) were treated for acute coronary syndrome. The site of perforation was most frequently distributed in the left anterior descending artery (40%), followed by the circumflex artery (28%) and right coronary artery (24%). The diameter of balloons for CBT ranged from 1.5 to 4.0 mm, with most balloons (76%) being either 2.0 or 2.5 mm in diameter. Most balloons (88%) were previously used for lesion predilatation. The numbers of cut balloons needed to seal the perforation were 1, 2 and ≥3 in 48%, 20% and 32% of cases, respectively. The in-hospital prognosis was favorable, with cardiac tamponade requiring pericardiocentesis in only four (16%) patients. Neither emergency surgery nor cardiac death occurred.
Conclusions:
CBT is a safe, efficient and easy-to-implement technique for the embolization of coronary perforations. Most distal coronary perforations can be sealed with one or two fragments of cut balloons, obviating the need for additional devices.
