Making the Transition From Cardiac Missions to Autonomous Heart Surgery at a Nigerian Teaching Hospital: Challenges and Lessons Learned.

Open-Heart Surgery at the Lagos State University Teaching Hospital commenced in 2004. Early years were based on a Cardiac Mission Model, but since 2017 the focus was on the transition to a Local Team Model with autonomous Open-Heart Surgery. The aim of this study is to describe our progress in making this transition, highlight lessons learned, and detail the outstanding challenges to be overcome.

Metal allergy to Amplatzer occluder device presented as severe bronchospasm.

Percutaneous closure of an atrial septal defect has become increasingly popular among interventional cardiologists. With this relatively new technology being more widespread, it is important to acknowledge any device-related complications. We report a case of severe bronchospasm secondary to a metal allergy after an atrial septal defect device closure requiring device removal.

Left ventricular assist device malfunction: an approach to diagnosis by echocardiography.

Objectives: A protocol using transthoracic echocardiography was designed to diagnose the common malfunctions of patients on chronic support with a left ventricular assist device (LVAD).

Background: Mechanical circulatory support, primarily with a LVAD, is increasingly used for treatment of advanced heart failure as a bridge to transplant and for long-term treatment of heart failure. The LVAD dysfunction is a recognized complication.

Left ventricular assist device malfunction: a systematic approach to diagnosis.

Objectives: A protocol was designed to diagnose the common malfunctions of a left ventricular assist device (LVAD).

Background: Mechanical circulatory support, primarily with an LVAD, is increasingly used for treatment of advanced heart failure (HF). Left ventricular assist device dysfunction is a recognized complication; but heretofore, a systematic method to accurately diagnose LVAD dysfunction has not been thoroughly described.
