Meta Analysis
Should the mitral valve be repaired for moderate ischemic mitral regurgitation at the time of revascularization surgery?
Ischemic mitral regurgitation (IMR) is associated with increased mortality and recurrent congestive heart failure following coronary artery bypass graft (CABG) surgery. While mitral surgery should be undertaken for severe MR during CABG, the treatment of moderate IMR remains controversial. We conducted a meta-analysis to determine the outcomes of CABG alone and combine with mitral valve repair (MVr) in moderate IMR. ⋯ Our results show that in the presence of moderate IMR, adding MVr to revascularization reduces MR grade on follow-up echocardiography and promotes ventricular remodeling, with no improvement in long-term survival or functional class.

Stroke and transient ischemic attack after transcatheter aortic valve replacement results in significantly higher morbidity and mortality. Severe carotid artery disease may be a contributing factor to this increased risk. We report our technique and outcomes of combined carotid endarterectomy (CEA) with transcatheter aortic valve replacement (TAVR). ⋯ The use of concomitant CEA and TAVR in patients with severe aortic stenosis and severe carotid stenosis can be done safely without increased risk of complications. This approach may reduce the risk of stroke associated with TAVR in appropriately selected patients.

A variety of cardioplegic solutions are being used widely today to arrest the heart during coronary artery bypass grafting (CABG) and other cardiac operations. To minimize interruptions during the surgery for intermittent dosing of the cardioplegia and to facilitate less invasive cardiac procedures, single-shot solutions, including Bretschneider and del Nido solutions, have been introduced. This review examines the evidence regarding the safety and efficacy of Bretschneider and del Nido cardioplegia during CABG. The findings support their use in routine low-risk CABG, but finds insufficient evidence to support their safety in high-risk surgeries.

Circumflex aorta and double aortic arch are two forms of rare vascular rings. We present a case of an infant who was diagnosed with circumflex aorta and double aortic arch, and describe the surgical management of this rare anomaly.
