First human experience with stent-based ventricle-to-coronary artery bypass.
Stent-based ventricle-to-coronary artery bypass (VSTENT) has been shown experimentally to provide systolic instead of physiological diastolic blood flow directly from the left ventricle to a coronary artery distal to a high-grade stenosis. We report on the first successful surgical implantation of a VSTENT in a patient with coronary artery disease. At 3-month follow-up, the VSTENT was patent and showed sufficient regional blood flow at rest with a significant flow reserve. In addition, the patient was asymptomatic during exercise testing. Though encouraging, these observations have to be confirmed and are the subject of an ongoing multicenter study.
