Double-root inversion for complex malposition of the great arteries with tricuspid valve straddling.

Multimed Man Cardiothorac Surg 2021 03 8;2021. Epub 2021 Mar 8.

University Hospital of Geneva University Hospital of Laussane Switzerland.

Dextro-transposition of the great vessels associated with pulmonary stenosis, double-outlet right ventricle, and straddling of the tricuspid valve is an uncommon condition. Several treatment options are available for this malformation, but most of them are not optimal. For patients with transposition of the great vessels, the gold standard procedure, which is an arterial switch procedure, would usually be performed, whereas for patients with pulmonary stenosis, a Rastelli operation or a Nikaidoh procedure would be proposed.

Lateral Heterotaxy Syndrome in a Newborn Caucasian Male.

Cureus 2020 Oct 27;12(10):e11205. Epub 2020 Oct 27.

Pathology, Anatomy, Laboratory Medicine, West Virginia University School of Medicine, Morgantown, USA.

Heterotaxy syndrome is a varied spectrum of rearrangements of thoracic and abdominal organs that present many unique complications. Among all congenital deformities, heterotaxy syndrome is rare although this is likely an underestimate without routine imaging due to the benign nature of some defects. Numerous genes have been identified that play a role in its pathogenesis, and it has been hypothesized that heterotaxy syndrome is a consequence of both genetic and environmental impacts on the body axis.

Echocardiographic diagnosis of permanent pacemaker lead malposition in the left ventricle: A case study.

Echocardiography 2020 12 20;37(12):2163-2167. Epub 2020 Nov 20.

Echocardiography Department, Freeman Hospital, Newcastle upon Tyne, UK.

Inadvertent endocardial lead malposition is recognized as a rare incident which is usually underreported and if recognized during implantation can be easily corrected. This phenomenon is caused by the ventricular lead unintentionally crossing a pre-existing patent foremen ovale, septal defects (atrial or ventricular) or directly from the aorta via an accidental subclavian puncture resulting in the lead implanting into the left ventricle. While this is a rare occurrence we report, the incidental finding of pacemaker lead malposition during a routine follow-up transthoracic echocardiogram and the benefits of three-dimensional transesophageal echocardiography in this patient prior to lead extraction.

Reducing regional flow stasis and improving intraventricular hemodynamics with a tipless inflow cannula design: An in vitro flow visualization study using the EVAHEART LVAD.

Artif Organs 2019 Sep 9;43(9):834-848. Epub 2019 Jun 9.

B-Squared Medical Device Solutions, Fort Worth, Texas.

Due to the high stroke rate of left ventricular assist device (LVAD) patients, reduction of thrombus has emerged as an important target for LVAD support. Left ventricular blood flow patterns with areas of flow stasis and recirculation are associated with platelet aggregation, which is worsened by exposure to high shear stress. Previous reports of intraventricular thrombus in LVAD patients have identified the outside of the LVAD inflow cannula as a nidus for LV thrombus formation. Read More

Virtual Fitting and Hemodynamic Simulation of the EVAHEART 2 Left Ventricular Assist Device and Double-Cuff Tipless Inflow Cannula.

ASAIO J 2019 Sep/Oct;65(7):698-706

From the enmodes GmbH, Aachen, Germany.

Inflow malposition during surgery, postoperative pump migration, inflow obstruction, and right ventricular compression are major contributors to low flow and adverse events in patients with ventricular assist devices (VADs). These position abnormalities can lead to adverse events including ischemic stroke. To address these problems, we conducted a virtual anatomical fitting study and hemodynamic simulation on iterative cannula designs, resulting in the EVAHEART 2 with the novel double-cuff tipless (DCT) inflow cannula and smaller pump design.

Inadvertent defibrillator lead placement into the left ventricle after MitraClip implantation: A case report.

Medicine (Baltimore) 2018 May;97(19):e0733

Division of Cardiology, Department of Medical and Surgical Sciences, "Magna Graecia" University URT-CNR, Department of Medicine, Consiglio Nazionale delle Ricerche, Catanzaro, Italy.

Rationale: Inadvertent pacemaker/defibrillator lead placement into the left ventricle is an unusual cardiac device-related complication and its diagnosis is not always easy and often misunderstood. Thromboembolic events are frequently associated with this procedural complication. Percutaneous lead extraction should be performed when diagnosis is made early after device implantation while long-life oral anticoagulation is a wise option when the diagnosis is delayed and the lead is not removed.

The Effect of Inflow Cannula Angle on the Intraventricular Flow Field of the Left Ventricular Assist Device-Assisted Heart: An In Vitro Flow Visualization Study.

ASAIO J 2019 02;65(2):139-147

From the Bioengineering Program, Department of Mechanical Engineering, San Diego State University (SDSU), San Diego, California.

Previous studies have identified left ventricular assist device (LVAD) inflow cannula (IC) malposition as a significant risk for pump thrombosis. Thrombus development is a consequence of altered flow dynamics, which can produce areas of flow stasis or high shear that promote coagulation. The goal of this study was to measure the effect of IC orientation on the left ventricle (LV) flow field using a mock circulatory loop, and identify flow-based indices that are sensitive measures of cannula malposition.

Inadvertent Left Ventricle Endocardial or Uncomplicated Right Ventricular Pacing: How to Differentiate in the Emergency Department.

J Emerg Med 2018 05 6;54(5):e91-e95. Epub 2018 Mar 6.

Department of Cardiology, Siyami Ersek Thoracic and Cardiovascular Surgery Center, Training and Research Hospital, Istanbul, Turkey.

Background: Temporary transvenous pacemaker implantation is an important and critical procedure for emergency physicians. Traditionally, temporary pacemakers are inserted by electrocardiography (ECG) guidance in the emergency department because fluoroscopy at the bedside in an unstable patient can be limited by time and equipment availability. However, in the presence of atrial septal defect, ventricular septal defect, and patent foramen ovale, the pacemaker lead can be implanted inadvertently into the left ventricle or directly into the coronary sinus instead of right ventricle.
