Valve-Sparing Aortic Root Replacement 3 Decades After Repair of Aortico-Left Ventricular Tunnel

Publication date: January 2020Source: The Annals of Thoracic Surgery, Volume 109, Issue 1Author(s): Safak Alpat, Keir A. Forgie, Isabelle VonderMuhll, Darren H. FreedAortico-left ventricular tunnel is a rare congenital anomaly requiring surgical repair early in childhood. After corrective surgery, such patients are at risk of developing aortic insufficiency and aortic root dilatation. Herein, we describe a valve-sparing aortic root replacement 3 decades after the repair of aortico-left ventricular tunnel.

PERCUTANEOUS REPAIR and replacement increasingly are being used to treat valvular heart disease. Adoption of these catheter-based techniques necessitates standardized methods for evaluating new or residual regurgitation after percutaneous valve repair or replacement. The American Society of Echocardiography guidelines document, “Guidelines for the Evaluation of Valvular Regurgitation After Percutaneous Valve Repair or Replacement,” addresses this need and provides a framework for evaluating regurgitation using echocardiography, invasive hemodynamic assessment, and cardiac magnetic resonance (CMR) imaging.

Personalized medicine is nowadays considered as the next disruptive evolution in the treatment of cardiovascular diseases, which remain the leading cause of mortality in the world [1]. Over the recent years, research has focused mainly on gene or cellular therapies [2]. In parallel, major developments have been made on trans-catheter implantable devices, such as coronary and peripheral stents, aortic valves and stent-grafts, which represent an increasing part of the cardiovascular therapeutic armamentarium.

AbstractThe potential of the MitraClip to prevent from right heart failure or to restore right ventricular (RV) function is still unclear. The aim of the present study was to analyze the impact of the MitraClip implantation on RV function and its association with clinical outcome. After MitraClip implantation patients underwent echocardiography follow-up scheduled between 3 and 6  months after the procedure in the present single-center registry. A total of 93 patients were included. Compared to baseline, RV function declined in 20%, was unchanged in 25% and improved in 55% of the patients. Factors associated with decl...

Authors: Orban M, Lüsebrink E, Braun D, Stocker TJ, Bagaev E, Hagl C, Näbauer M, Massberg S, Orban M, Hausleiter J Abstract Introduction: Heart failure (HF) and severe mitral regurgitation (MR) are mutually dependent. Secondary MR is a consequence of chronic heart failure with reduced left ventricular ejection fraction (HFrEF) and left ventricular (LV) dilatation. Severe MR worsens prognosis and accelerates LV dilatation as well as decline in LV ejection fraction. Interventional therapies have changed clinical practice for HF patients with secondary MR.Areas covered: In this review we summarize the availa...

AbstractFunctional tricuspid regurgitation (TR) results from asymmetric dilation of the tricuspid valve annulus. This often occurs due to right ventricular enlargement and dysfunction as a consequence of myocardial or valvular abnormalities of the left heart. Even mild TR at the time of left-sided valvular surgery may worsen postoperatively, which carries poor prognostic implications. In spite of data revealing poor outcomes associated with residual TR, surgery for functional TR remains underutilized. Surgical repair techniques for TR include placement of a rigid or semi-rigid tricuspid annular ring, which has been shown t...

ConclusionMyxomas are a rare primary tumors of the heart with a varied symptomatology. Echocardiography remains the main tool for diagnosis and follow-up. Surgery is the gold standard for treatment that remains burdened with low morbidity and mortality. The evolution is usually favorable, nevertheless, the recurrence remains possible justifying a regular clinical examination and echographic supervision.

ConclusionsA mapping of coaptation forces along the entire mitral valve surface can be achieved with the method and device we have developed. This technology may be useful to assist surgeons during MVr while providing real-time objective measurement in support of the conventional intraoperative morphological assessment. An extensive development roadmap has been developed and is being put in place to move our invention toward clinical trials.

ConclusionVSRR ensures excellent mid-term aortic valve function independently of its morphology. In B associated with aortic root aneurysm, leaflet repair does not increase the valve-related events.

RaimondiBackgroundAfter tetralogy of Fallot (TOF) repair, pulmonary regurgitation and right ventricular function must be monitored. Conventional (2D) cardiac magnetic resonance (CMR) is currently the clinical reference method for measuring pulmonary regurgitation. However, 4D CMR has been reported to provide a more comprehensive flow analysis than 2D CMR. We aimed to compare 4D CMR to 2D CMR for assessing pulmonary regurgitation and flow, as wel...

AbstractAortopathy is a recognized comorbidity of Tetralogy of Fallot (TOF). Aortic flow in children with repaired TOF is abnormal despite normal aortic valve anatomy and early surgical repair that results in aortic size normalization. The purpose of this study was to investigate the flow hemodynamics inside the left ventricle (LV) of children with repaired TOF using 4D-Flow MRI derived vorticity. Vorticity is the spatial derivative of flow velocity and is sensitive to anatomic and geometric variations. Vorticity was calculated inside the LV of children with repaired TOF having normal aortic size (n  = 14) an...
