An unusual problem associated with the use of left ventricular assist devices (LVADs) relates to malposition of the apical inflow cannula. From 2005 to 2010, we implanted 154 continuous-flow HeartMate II (Thoratec, Pleasanton, CA) LVADs at our institution. In 4 separate instances, patients appeared to have malposition of the inflow cannula that resulted in serious symptoms. All 4 patients underwent surgery to reposition the cannula. Successful outcomes were achieved for 3 of the 4 patients.

"Caution with choroidals" - choose the right one at right time.

Article Synopsis
- Choroidal detachment (CD) during retinal detachment surgery can negatively affect surgical results and vision, necessitating specific management techniques.
- Cannula-guided choroidal drainage is essential for mitigating pre-existing CDs, especially in complex cases with hemorrhagic detachment.
- Intraoperative sudden CD can be caused by issues like hypotony or air entry from cannula slippage, which may lead to serious complications like Venous Air Embolism (VAE); prompt action to stop air infusion is critical to prevent life-threatening outcomes.
A less-invasive left atrial assist device concept for diastolic heart failure: First in vitro and in vivo assessment.
JTCVS Open

Department of Biomedical Engineering, Lerner Research Institute, Cleveland Clinic, Cleveland, Ohio.
Objective: A less-invasive left atrial assist device (LAADx) is a novel and implantable, extracardiac blood pump concept, intended for the treatment of diastolic heart failure, represented by heart failure with preserved ejection fraction.
Methods: A mixed-flow pump was used as the working LAADx model. Its performance was evaluated at 3 speeds, using an in vitro pulsatile mock circulatory loop, with a pneumatic pump that can simulate diastolic heart failure conditions by adjusting the diastolic drive pressure.

Background And Objective: Right ventricular failure increases short-term mortality in the setting of acute myocardial infarction, cardiogenic shock, advanced left-sided heart failure and pulmonary arterial hypertension. Percutaneous and surgically implanted right ventricular assist devices (RVAD) have been investigated in different clinical settings. The use of the ProtekDuo™ is currently a promising approach due to its features such as groin-free approach leading to early mobilisation, easy percutaneous deployment, compatibility with different pumps and oxygenators, and adaptability to different configurations.

Article Synopsis
- Left ventricular assist devices (LVADs) are commonly used to treat advanced heart failure, improving survival but leading to high rates of arrhythmias (20-50%) within a year after implantation.
- Arrhythmias in these patients increase the risk of complications, such as additional shocks from implantable defibrillators and potential worsening of right ventricular failure, highlighting the need for tailored management strategies.
- Effective treatment for these arrhythmias may involve specialized approaches like catheter ablation, though unique challenges exist in accessing arrhythmogenic areas after LVAD surgery, making pre-implantation procedures potentially beneficial.

Introduction: The Protek Duo (PtD) dual lumen, single cannula was developed as a percutaneous system for temporary mechanical support, inserted through the internal jugular vein (IJ) for both atrial inflow and pulmonary artery outflow. Outcomes of PtD compared to alternative Peripheral Right Ventricular Assist Device (pRVAD) methods are limited.
Methods: A retrospective analysis was conducted of pRVAD recipients from January 2017 - February 2022 ( = 111).
