Reoperations on the pulmonary autograft and pulmonary homograft after the Ross procedure: An update on the German Dutch Ross Registry.

OBJECTIVES: Reinterventions after the Ross procedure are a concern for patients and treating physicians. The scope of the present report was to provide an update on the reinterventions observed in the large patient population of the German-Dutch Ross Registry. PATIENTS AND METHODS: From 1988 to 2011, 2023 patients (age, 39.05 ± 16.5 years; male patients, 1502; adults, 1642) underwent a Ross procedure in 13 centers. The mean follow-up was 7.1 ± 4.6 years (range, 0-22 years; 13,168 patient-years). RESULTS: In the adult population, 120 autograft reinterventions in 113 patients (1.03%/patient-ye

Transcatheter aortic valve replacement: outcomes of patients with moderate or severe mitral regurgitation.

OBJECTIVES: The aim of this study was to evaluate the impact of mitral regurgitation (MR) on outcomes after transcatheter aortic valve replacement (TAVR) and the impact of TAVR on MR. BACKGROUND: Little is known of the influence of MR on outcomes after TAVR. METHODS: The outcomes of patients with mild or less (n = 319), moderate (n = 89), and severe (n = 43) MR were evaluated after TAVR at 2 Canadian centers. RESULTS: Patients with moderate or severe MR had a higher mortality rate than those with mild or less MR during the 30 days after TAVR (adjusted hazard ratio: 2.10; 95% confidence inte

Risk factors for prosthesis failure in pulmonary valve replacement.

BACKGROUND: After initial right ventricular outflow tract reconstruction, replacement of the pulmonary valve (PVR) with a bioprosthetic valve may be performed. Bioprosthetic valves fail (PVF) and require repeat replacement. Identification of risk factors for PVF would be useful for clinicians choosing among various options for the initial PVR. METHODS: We retrospectively analyzed outcomes of 169 consecutive patients (55% male) with repaired tetralogy of Fallot or pulmonary stenosis undergoing a first PVR. Data were abstracted from the medical records, including gender, diagnosis, indication f

Bovine valved venous xenografts for RVOT reconstruction: results after 71 implantations.

BACKGROUND: Pediatric right ventricular outflow tract (RVOT) reconstruction with homo- or porcine xenografts is problematic because of limited availability, lack of material for reconstruction, early degeneration, and tissue ingrowth. Contegra, a bovine jugular vein graft, might be an interesting alternative to overcome these problems. PATIENTS AND METHODS: Within a Federal Drug Administration controlled study, we implanted 71 Contegra pulmonary valved conduits from May 1999 to September 2001 in 71 patients (male/female 33/38) in the age range 2 days-17.4 years, median 1.2 years. Twenty five

Nonusefulness of Antithrombotic Therapy After Surgical Bioprosthetic Aortic Valve Replacement.

Controversy persists regarding the advisability of anticoagulation for the early period after biological surgical aortic valve replacement (AVR). We aim to examine the impact of various antithrombotic regimens on outcomes in a large cohort of biological AVR patients. Records of 1,111 consecutive adult patients who underwent surgical biological AVR at our institution between 2013 and 2017 were reviewed. Outcomes included stroke, bleeding, and death at 3 and 12 months. Treatment regimens included (1) no therapy, (2) anticoagulants (warfarin or Factor Xa inhibitors), (2) antiplateles (various), a

Acute and Midterm Outcomes of Transcatheter Pulmonary Valve Replacement for Treatment of Dysfunctional Left Ventricular Outflow Tract Conduits in Patients With Aortopulmonary Transposition and a Systemic Right Ventricle.

BACKGROUND: Transcatheter pulmonary valve replacement (TPVR) is an established therapy for dysfunctional right ventricular (RV) outflow tract conduits. TPVR in patients with congenitally corrected transposition of the great arteries, subpulmonary left ventricle, and left ventricular outflow tract (LVOT) conduit dysfunction has not been studied. Unique anatomic and physiological aspects of this population may contribute to distinct risks and outcomes. METHODS AND RESULTS: Across 10 US centers, 27 patients with a dysfunctional LVOT conduit were evaluated in the catheterization laboratory betwee

Multiplug paravalvular leak closure using Amplatzer Vascular Plugs III: A prospective registry.

BACKGROUND: Transcatheter paravalvular leak closure (TPVLC) offers a viable alternative to reoperation but optimal technical strategy is still to be defined. We present a prospective TPVLC registry in which safety and efficacy of multi-plug, single-stage approach were assessed. METHODS: Patients with heart failure (HF) symptoms caused by PVL were qualified for TPVLC by Heart Team. Ante- or retrograde access was employed for mitral while retrograde only for aortic PVLs. Two to 4 AVP 3 devices were simultaneously implanted into each PVL. Endpoints were defined according to VARC-2. RESULTS: Fro

Best of JACC: Case Reports From ACC.23.

This dedicated issue of JACC: Case Reports highlights the top ranked Complex Clinical Cases from the ACC 2023 Scientific Sessions. These cases were reviewed and selected by a committee of peers in the months leading up to the annual meeting. These reviewers were ACC members with no affiliation to the JACC: Case Reports Editorial Board. While the cases were presented at the meeting and included in the formal Abstract Book from ACC, they have not been published elsewhere. These cases illustrate how the ACC can be a place for cardiovascular professionals to come together to learn, grow, and share

Aortic valve surgery: marked increases in volume and significant decreases in mechanical valve use--an analysis of 41,227 patients over 5 years from the Society for Cardiothoracic Surgery in Great Britain and Ireland National database.

OBJECTIVES: Aortic valve replacement is accepted as a standard treatment for aortic stenosis and regurgitation. To help plan the national requirement for conventional and catheter-based procedures, we have analyzed the Society for Cardiothoracic Surgery in Great Britain and Ireland audit database to look at changes in practice over time. METHODS: All patients undergoing conventional aortic valve replacement with or without coronary artery surgery from April 2004 to March 2009 were included. The main outcome measures were changes in the number, characteristics, operative details, and in-hospit

Is early antithrombotic therapy necessary in patients with bioprosthetic aortic valves in normal sinus rhythm?

OBJECTIVE: Current American Heart Association/American College of Cardiology guidelines recommend anticoagulation and antiplatelet therapy during the first 90 postoperative days; however, there is wide variability in the administration of antithrombotic therapy after bioprosthetic aortic valve replacement. We sought to determine whether early antithrombotic therapy was necessary in patients undergoing isolated bioprosthetic aortic valve implantation and who were discharged in normal sinus rhythm. METHODS: From December 2001 to October 2008, 1131 patients underwent isolated bioprosthetic aorti

Risk factors for development of endocarditis and reintervention in patients undergoing right ventricle to pulmonary artery valved conduit placement.

OBJECTIVE: To determine the incidence and risk factors for endocarditis and reintervention in patients undergoing placement of right ventricle-to-pulmonary artery valve conduits. METHODS: All right ventricle-to-pulmonary artery valved conduits placed between 1995 and 2014 were included. Freedom from endocarditis, reintervention, and replacement were analyzed using the Kaplan-Meier method and parametric survival regression models. RESULTS: A total of 586 patients underwent placement of a total of 792 valved conduits, including 289 (36%) pulmonary homografts, 121 (15%) aortic homografts, 245 (
