Prevalence and Predictors of Coronary Artery Perforation During Percutaneous Coronary Interventions (from the ORPKI National Registry in Poland).

Coronary artery perforation (CAP) is a rare but potentially life-threatening complication of percutaneous coronary intervention (PCI). With a growing number of PCIs in complex lesions, the problem of CAP becomes even more important nowadays. Data on CAP rates in Poland are lacking. Presented study is an analysis of 344,517 consecutive patients treated with PCI between 2014 and 2017. Data were gathered from the Polish National PCI Registry (ORPKI). During 4 years of data collection CAP was observed in 595 (0.17%) cases. Patients diagnosed with CAP were older (69 years Q1:63; Q3:78 vs 66 years Q1:60; Q3:75; p <0.001), more often female (44% vs 32%; p <0.001), with arterial hypertension (77% vs 71%; p = 0.002), and chronic kidney disease (8.9% vs 5.4%; p <0.001). In the CAP group, a higher rate of PCIs within chronic total occlusions (8.7% vs 2.3%; p <0.001) and saphenous vein graft lesions (2.7% vs 1.3%; p = 0.002), as well as rotational atherectomy procedures (2.2% vs 0.4%; p <0.001) was observed. Patients with CAP had higher rate of no-reflow phenomenon (5.5% vs 0.5%; p <0.001) and greater periprocedural mortality (4.2% vs 0.5%; p <0.001). In conclusion, our study confirms that CAP is more common during complex PCI procedures in high-risk patients. CAP occurrence is associated with worse immediate outcomes including increased periprocedural mortality.
