To the Editor:A 54-year-old man was admitted for progressive chest pain.Four years ago,the patient had surgical aortic valve replacement (SAVR),and preoperative multislice computed tomography (MSCT)showed no coronary stenosis.A year after SAVR,he presented with chest pain,and coronary angiogram revealed an isolated ostial left main coronary artery (LMCA) stenosis [Figure 1a].A 4.0mm × 18.0mm stent (Medtronic Vascular, Santa Rosa,CA,USA)was implanted without a high-pressure postdilation [Figure 1b].The patient was discharged on aspirin, ticagrelor (replaced with clopidogrel after 3months),and statins. Unfortunately,the stent was found to protrude into the aorta by approximately 10mm by MSCT at 4-month follow-up [Figure 1c].
