- Abstract
Objectives: Post-dilatation with non-compliant (NC) balloons is a commonly used strategy to improve inadequate stent expansion but this strategy carries an increased risk of slow flow/no - reflow (SF/NR) due to distal embolization. Therefore, our objective was to evalua te the demographic, clinical, angiographic, and procedure characteristics among patients undergoing primary percutaneous coronary intervention (PCI) who developed slow flow/no-reflow (SF/NR) after post-dilatation with non-compliant (NC) balloons. Methodology: In this cross-sectional observational study, we included consecutive patients with SF/NR after post-dilatation using NC balloon post stent deployment during primary PCI. The demographic, clinical, angiographic, and procedure characteristics were eva luated. Results: In the sample of 107 patients, male were 77.6% (83) and mean age was 56.94 ± 10.47 years. The median chest pain to ER (emergency room) arrival time was 292 [180-394] minutes. A majority of the patients (66.4%) had multi-vessel disease. Mean length NC balloon was 10.57±1.98 mm and diameter was 3.5±0.26 mm. The mean number of inflation were 3.62±1.08, at mean maximal pressure of 20.43±2.49 mmHg, proximal edge pressure of 19.25±2.74 mmHg, and distal edge pressure of 14.64±2.01 mmHg. A total of 5.6% (6) patients developed adverse events and final TIMI (thrombolysis in myocardial infarction) III flow was achieved in 89.7% (96) of the patients. Conclusion: SF/NR after post-dilatation during primary PCI is associated with a significant rate of adverse events and sub-optimal (<III) final TIMI flow. The detrimental effects of high pressure, short length, and increased number of inflations on post NC SF/NR need further investigations.
