Beating Heart – HIV-to-HIV Heart – Partial Heart

Heart Transplant

By Luc Puis Let’s talk transplantation today. Last Thursday, September 29, was International Heart Day, so let’s take heart. Three remarkable, first in-heart transplantations happened, extending life and expanding the donor pool. On the China Circuit A team in China performed the first ischaemic-free, beating heart transplantation in a human. By combining adapted surgical techniques…

LivaNova (TandemLife) Recalls LifeSPARC System for Risk of Unintentional Extended Pump Stop During Controller Critical Failure


By Luc Puis LivaNova (TandemLife) is recalling the LifeSPARC Controller, part of the LifeSPARC System, due to a software malfunction that may trigger the device to enter Critical Failure mode—clearing the controller screen and issuing an alarm that cannot be muted or turned off. While the LifeSPARC Pump should continue to run at the set…

Playing Cupid, an Arrow Through the Heart

By Luc Puis “How was your day, honey?” “Well, I did something really stupid, and then I was extremely lucky to survive it…” In a nutshell, this happened to a 54-year-old man in Canada when he was preparing his crossbow, used for hunting large animals. Due to reasons not described in detail in this article,…

Awake Extracorporeal Life Support and Physiotherapy in Adult Patients: A Systematic Review of the Literature

Awake ECLS strategy associated with physiotherapy is performed regardless of cannulation approach. Ambulation, as main objective, is achieved in almost half the population examined. Prospective studies are needed to evaluate safety and efficacy of physiotherapy during Awake ECLS, and suitable patient selection. Guidelines are required to identify appropriate assessment/evaluation tools for Awake ECLS patients monitoring.

Incidence and Outcome of Anaphylaxis in Cardiac Surgical Patients


As all patients survived, our results provide preliminary support for proceeding with surgery although we cannot speculate on the likely outcomes of patients who were postponed, had their surgery proceeded. Based on our data, the incidence of anaphylaxis in cardiac surgical patients may be 10–20 times higher than in the general surgical population.

Cannulas and Cannulation Options for Minimally Invasive Surgery

Traditionally, cardiac surgery has been practiced primarily through a median sternotomy; however, as instrumentation and experience continue to advance at exponential rates, the field of minimally invasive cardiac surgery (MICS) is rapidly expanding. When compared with a conventional sternotomy, alternative access offers patients the potential benefits of decreased infection risk, reduced transfusion requirements, decreased length of admission, quicker return to normal activity, and, perhaps most important for patients, improved cosmesis. We hereby discuss our approach to cannulation for MICS operations.

Effect Of Aortic Cannulation Depth on Air Emboli Transport during Cardiopulmonary Bypass: A Computational Study.


It was demonstrated that the elongated cannula insertion length resulted in lower embolic loads, particularly at a higher flow rate. The numerical results suggest that CPB management could combine active flow variation with improving cannula performance and provide a foundation for a future experimental and clinical investigation to reduce surgical cerebral air microemboli.

A Prospective Observational Study on the Effect of Emboli Exposure on Cerebral Autoregulation in Cardiac Surgery Requiring Cardiopulmonary Bypass.

Overall, change in mean velocity index before and after cross-clamp removal did not differ between groups. However, most emboli entered the right cerebral hemisphere where this change was significantly greater in the open-chamber group, suggesting a possible association between embolic exposure and dysautoregulation.

Effect of Nitric Oxide via Cardiopulmonary Bypass on Ventilator-Free Days in Young Children Undergoing Congenital Heart Disease SurgeryThe NITRIC Randomized Clinical Trial

In children younger than 2 years undergoing cardiopulmonary bypass surgery for congenital heart disease, the use of nitric oxide via cardiopulmonary bypass did not significantly affect the number of ventilator-free days. These findings do not support the use of nitric oxide delivered into the cardiopulmonary bypass oxygenator during heart surgery.
