Abstract

Coronary artery occlusion is an uncommon but life-threatening complication of transcatheter aortic valve replacement (TAVR). Both low coronary artery height and externally mounted stented bioprosthesis present an increased risk for coronary artery occlusion, and various prevention strategies have been recommended. We present an 86-year-old woman with failed surgical bioprosthesis, concomitant obstructive ostial right coronary artery (RCA) lesion, and low coronary ostial heights who underwent simultaneous TAVR and percutaneous coronary intervention of ostial RCA. Due to suprannular valve expansion after post-dilation, the RCA ostium was compromised, and a novel stent tunnel was created under the native leaflets towards the left coronary sinus to maintain RCA perfusion.

Abstract

Background: Low QRS voltage was reported to predict adverse outcomes in acute myocardial infarction in the pre-thrombolytic era. However, the association between low voltage and angiographic findings has not been fully addressed.Methods: We performed a retrospective analysis of patients with anterior ST-segment elevation myocardial infarction (STEMI). Low QRS voltage was defined as either peak to peak QRS complex voltage <1.0mV in all precordial leads or <0.5mV in all limb leads.Results: Among 190 patients, 37 patients (19%) had low voltage. Patients with low voltage had a higher rate of multi-vessel disease (MVD) (76% vs. 52%, p=0.01). Patients with low voltage were more likely to undergo coronary artery bypass grafting (CABG) during admission (11% vs. 2%, p=0.028). Low voltage was an independent predictor for MVD (OR 2.50; 95% CI 1.12 to 6.03; p=0.032).Conclusion: Low QRS voltage was associated with MVD and in-hospital CABG in anterior STEMI.
