J Heart Valve Dis 2018 Jan;27(1):124-126

Cardiac Surgery Unit, Heart Center, Grande Ospedale Metropolitano 'Bianchi-Melacrino-Morelli', Reggio Calabria, Italy.

A 76-year-old woman was admitted to the authors' hospital with pulmonary edema five months after the successful implantation of a Perceval sutureless aortic valve (Sorin Group Srl, Saluggia, Italy). Both echocardiography and computed tomography scanning demonstrated migration of the aortic valve into the left ventricle, causing severe aortic and mitral (secondary) insufficiency. Following heart team discussions, the sutureless valve was replaced with a standard bioprosthesis (Perimount, Magna Ease; Edwards Lifesciences, Irvine, California, USA) with spontaneous restoration of native mitral valve competence.

Melody valve in mitral position: Complete fracture causing acute mitral stenosis in a child.

Catheter Cardiovasc Interv 2019 Feb 31;93(2):E101-E104. Epub 2018 Oct 31.

Division of Pediatric Cardiology, Mayo Clinic, Rochester, Minnesota.

We present a case of a 7-year-old boy with a history of multiple mitral valve interventions and subsequent Melody valve placement in the mitral position, who presented with acute mitral stenosis due to complete fracture of the Melody stent. He was born early with severe mitral and tricuspid insufficiency due to valvular dysplasia, and ended up with 4 sternotomies before the age of 2 due to mitral valve dysfunction and recurrent prosthetic valve thrombosis. He then developed mixed stenosis and regurgitation at age 6, and to avoid another sternotomy, valve-in-valve therapy with off-label use of a 20-mm Melody valve was done with hybrid procedure via trans-apical approach.

Lund University, Department of Clinical Sciences, Lund, Clinical Physiology, Skåne University Hospital , Sweden.

Intracardiac hemodynamic forces have been proposed to influence remodeling and be a marker of ventricular dysfunction. We aimed to quantify the hemodynamic forces in patients with repaired tetralogy of Fallot (rToF) to further understand the pathophysiological mechanisms as this could be a potential marker for pulmonary valve replacement (PVR) in these patients. Patients with rToF and pulmonary regurgitation (PR) > 20% ( n = 18) and healthy control subjects ( n = 15) underwent MRI, including four-dimensional flow. Read More

Monocusp valve placement in children with tetralogy of Fallot undergoing repair with transannular patch: A functioning pulmonary valve does not improve immediate postsurgical outcomes.

Congenit Heart Dis 2018 Nov 27;13(6):935-943. Epub 2018 Sep 27.

Division of Pediatric Cardiothoracic Surgery, Medical College of Wisconsin, Herma Heart Institute at Children's Hospital of Wisconsin, Milwaukee, Wisconsin.

Introduction: In patients with tetralogy of Fallot (TOF), use of transannular patch (TAP) may be required in order to relieve significant right ventricular outflow tract obstruction, subsequently resulting in pulmonary insufficiency (PI). The monocusp valve has been used to temporarily reduce insufficiency in hopes to improve short and midterm outcomes. The purpose of this study was to assess for potential benefits of the monocusp valve in this subset of patients. Read More

Comparison of Early and Long-Term Outcomes After Transcatheter Aortic Valve Implantation in Patients with New York Heart Association Functional Class IV to those in Class III and Less.

Am J Cardiol 2018 Nov 21;122(10):1718-1726. Epub 2018 Aug 21.

Catheterization Laboratory, Cardiothoracic Department, Spedali Civili Brescia, Brescia, Italy.

Our aim was to investigate the impact of a baseline New York Heart Association (NYHA) class IV on clinical outcomes of a large real-world population who underwent transcatheter aortic valve implantation (TAVI). The primary end points were all-cause mortality, cardiovascular mortality, and re-hospitalization, evaluated at the longest available follow-up and by means of a 3-month landmark analysis. The secondary end points were: change in NYHA class, left ventricular ejection fraction, pulmonary pressure and mitral regurgitation. Read More

Noninvasive determination of the pulmonary artery input impedance.

Med Hypotheses 2018 Nov 9;120:7-13. Epub 2018 Aug 9.

Faculty of Mechanical Engineering and Naval Architecture, University of Zagreb, Ivana Lučića 5, 10000 Zagreb, Croatia.

A reliable noninvasive method for the estimation of pulmonary function in healthy and diseased subjects should be of great importance in the prognosis, diagnosis, and treatment of pulmonary hypertension. Here we propose such a method, which is based on the parameter identification of the five-element Windkessel model of pulmonary circulation. The method requires the following input variables: the heart rate, the stroke volume, the Doppler echocardiographic measurements of the tricuspid regurgitation and the pulmonary valve velocity profiles, and estimations of the right atrium and the pulmonary vein pressure.

The Modified Ross Procedure with Prosthetic Graft Wrap Does Not Prevent Autograft Failure.

J Heart Valve Dis 2017 11;26(6):735-737

Duke University Medical Center, Durham, NC, USA, Electronic correspondence:

The modified Ross procedure, which involves replacement of the aortic valve with a pulmonary autograft root supported within a Dacron tube graft, was developed with the goal of preventing late autograft dilatation and associated aortic insufficiency. The case is reported of an adult patient who had a bicuspid aortic valve (BAV), underwent a modified Ross procedure, and developed severe aortic insufficiency within one year and subsequently required reoperation for aortic valve replacement. While advances have been made to increase the success of the Ross procedure via modifications to prevent aortic root dilatation, no modifications have yet been devised to improve the ability of the pulmonary valve to withstand systemic aortic pressures.

Red Cell Distribution Width as a Prognostic Marker in Patients Undergoing Valve Surgery.

J Heart Valve Dis 2017 11;26(6):714-720

Institute of Cardiology, Department of Acquired Cardiac Defects, Warsaw, Poland.

Background: Numerous studies have shown that elevated red cell distribution width (RDW) is associated with poor outcomes in patients with cardiovascular diseases such as acute myocardial infarction, stroke, and chronic heart failure. The prognostic utility of RDW in patients with valvular disease undergoing heart valve surgery is unknown.

Methods: A prospective study was conducted on a group of consecutive patients with hemodynamically significant valvular heart disease that underwent elective valvular surgery. Read More
