Effects of varying blood flow rate during peripheral veno-arterial extracorporeal membrane oxygen (V-A ECMO) on left ventricular function measured by two-dimensional strain.

Background: We evaluated the effects of varying blood flow rate during peripheral veno-arterial extracorporeal membrane oxygen (V-A ECMO) on left ventricular function measured by two-dimensional strain.

Methods: Adult patients who were supported by peripheral V-A ECMO were recruited. Serial hemodynamic and cardiac performance parameters were measured by transthoracic echocardiogram within the first 48 h after implementation of V-A ECMO.

Sensitivity of ventricular systolic function to afterload during veno-arterial extracorporeal membrane oxygenation.

Aims: Veno-arterial extracorporeal membrane oxygenation (V-A ECMO) increases afterload to the injured heart and may hinder myocardial recovery. We aimed to compare the sensitivity of left ventricular (LV) systolic function to the afterload effects of peripheral V-A ECMO during the acute and delayed stages of acute myocardial dysfunction.

Methods And Results: A total of 46 adult patients who were supported by peripheral V-A ECMO between April 2019 and June 2021 were analysed.

Respiratory arrest requiring resuscitation as a rare presentation of obstructive sleep apnoea and hypothyroidism.

A 79-year-old man, who had significant cardiovascular morbidities, presented with out-of-hospital respiratory arrest. He regained breathing after brief cardiopulmonary resuscitation by his paramedic son. After meticulous investigations, acute cardiovascular events and metabolic causes were ruled out while features of obstructive sleep apnoea were elicited.
