Pulsatile flow left ventricular assist devices (PF-LVADs) have successfully supported patients with severe heart failure for bridge-to-transplant (BTT) and destination therapy (DT). End-organ dysfunction is often reversed, optimizing the patient's condition to enhance survival, and quality of life. Questions have been raised regarding the potential for continuous flow LVADs (CF-LVADs) to provide the same quality of circulatory support. ⋯ There are anecdotal cases of patients being supported with a CF-LVAD for over seven years with preserved end-organ function. Presently, there are no clinical reports indicating that end-organ function is not well maintained. Current clinical evidence indicates that end-organ perfusion and function can be well maintained for extended durations of support with a CF-LVAD.

Comparative Study
Symptomatic young infants with tetralogy of fallot: one-stage versus staged repair.
Debate continues over the optimal timing for total repair of tetralogy of Fallot. Here, we report our experience with early one-stage total repair of tetralogy of Fallot. ⋯ Early one-stage total repair of tetralogy of Fallot can be performed safely without increasing the risk for reoperation or reintervention, in the short term. The pulmonary annulus is likely to be preserved when it is repaired at an early age. Early total repair may be better for the pulmonary arterial growth than staged repair.

One of the unique variables for successful implantation of transcatheter aortic valves involves the ability to secure an access route for deployment of the aortic valve. ⋯ The article review highlights the various percutaneous, hybrid, and surgical access techniques platforms available as well as options for implantation of these devices.

We present a case of a displaced atrial septal defect (ASD) occluder in the left ventricle. We successfully adapted a strategy to remove the device through a single right atrial incision which permitted retrieval of the occluder and the closure of the ASD.

Thoracic endovascular aortic repair of an aberrant right subclavian artery: technique and long-term outcome.
Aberrant right subclavian artery (ARSA) is the most common congenital arch anomaly, which can be complicated by aneursymal dilation at its ostium. We describe a successful repair of an ARSA with a three-stage operative procedure using a left carotid to subclavian bypass, coiling of the ARSA, and thoracic endovascular aortic repair with long-term clinical and radiographic follow-up.
