Lauro Cortigiani, Fausto Rigo, Sonia Gherardi, Francesco Bovenzi, Sabrina Molinaro, Eugenio Picano4 and Rosa Sicari

Aims Myocardial ischaemia during pharmacological stress echocardiography is a strong prognostic predictor in patients with a left bundle branch block (LBBB). However, the additive value of Doppler-derived coronary flow reserve (CFR) during pharmacological stress testing remains to be investigated in this subset of patients.

Background—With the availability of transcatheter aortic valve replacement, management of coronary artery disease in patients with severe aortic stenosis (AS) is posing challenges. Outcomes of percutaneous coronary intervention (PCI) in patients with severe AS and coronary artery disease remain unknown. We sought to compare the short-term outcomes of PCI in patients with and without AS.

JACC: CARDIOVASCULAR INTERVENTIONS. Late Complication. Xience V Stent Fractures With Restenosis

Jason R. Foerst, MD; Timothy C. Ball, MD, PhD; Masataka Nakano, MD; Renu Virmani, MD; Aaron V. Kaplan, MD

A 70-year-old morbidly obese woman with severe emphysema presented with unstable angina. Coronary angiography revealed high-grade, calcified, ostial left circumflex (LCX) and distal right coronary artery (RCA) lesions. She was deemed a high-risk surgical candidate and underwent stenting of the left main coronary artery into the LCX with a 3.5 × 18-mm Xience V stent (Abbott Vascular, Santa Clara, California). A second 3.5 × 18-mm Xience V stent was overlapped distally to cover a mid LCX lesion, and both stents were post-dilated to 16 atm with a 3.5-mm noncompliant balloon. The RCA lesion was stented with a 3.0 × 12-mm Xience V and post-dilated to 16 atm with a 3.0-mm noncompliant balloon (Figure 1). The patient did well for 6 months until she returned with unstable angina. Angiography revealed restenosis at the ostium of the stented LCX and within the distal RCA stent (Figure 1). During repeat intervention, wiring of the LCX resulted in abrupt closure. The patient developed refractory ventricular fibrillation and died.
