Valve-Sparing Root Replacement: Aortic Root Remodeling with External Subvalvular Ring Annuloplasty.

ABSTRACT: The original valve-sparing procedures for aortic root aneurysms were remodeling and reimplantation of the aortic root. The remodeling technique provides more physiologic movement of the cusps within 3 reconstructed neo-sinuses, thus preserving root expansibility through the interleaflet triangles. However, the durability of remodeling has been a matter of concern due to the high rate of aortic insufficiency when annular dilation is not addressed. Therefore, a modified approach was developed, combining a physiologic remodeling of the root with a subvalvular annuloplasty. This case report highlights the first case of successful aortic root remodeling with external subvalvular ring annuloplasty in Korea.

Transcatheter Aortic Valve Replacement for Bicuspid Aortic Insufficiency After Valve-Sparing Aortic Root Replacement.

Project description:Bicuspid aortic insufficiency (BAI) patients with root aneurysm often require aortic valve and root replacement in a composite procedure. The valve-sparing root replacement (VSARR) procedure is aimed at preserving the native valve when possible. This case highlights a successful transcatheter aortic valve replacement procedure in a BAI patient previously treated with VSARR. (Level of Difficulty: Intermediate.).

Comparison of the Bentall procedure versus valve-sparing aortic root replacement.

Project description:Bentall and valve-sparing root replacement (VSRR) procedures are established treatments for aortic root disease. We present a single-center retrospective analysis comparing outcomes of bioprosthetic Bentall (BB), mechanical Bentall (MB), and VSRR patients from November 2007 to October 2016. Survival analysis was performed to evaluate the composite endpoint of freedom from recurrent aortic insufficiency, reoperation, or death. Of the 170 patients, BB was performed in 36 patients, MB in 63 patients, and VSRR in 71 patients. For BB, MB, and VSRR, the mean age was 63.8, 45.5, and 49.2 years (P?<?0.001), respectively. Additionally, significantly more patients in the MB group (n = 32, 50.8%, P?<?0.001) than in the BB and VSRR groups had prior cardiac surgeries. Cardiopulmonary bypass time and cross-clamp time were significantly longer in the VSRR group (P = 0.04 and 0.0005, respectively). Despite the complexity of the procedure, VSRR patients had higher combined freedom from death and reoperation than patients in the BB or MB groups. Elective Bentall root replacement is an excellent option for patients with root disease. Patients undergoing Bentall tend to have more severe or emergent cases, making them unlikely candidates for VSRR. VSRR in experienced centers carries equivalent morbidity and mortality and improved survival.

Hemolytic Anemia After an Aortic Dissection Treated With a Valve-Sparing Aortic Root Replacement.

Project description:A 46-year-old man with a personal history of a repaired aortic dissection was admitted because of hemolytic anemia. The transesophageal echocardiogram displayed an accelerated flow and a residual intimal flap in the proximal descending aorta. A total arch replacement was performed, the flap was removed, and his hemolytic anemia was resolved. (Level of Difficulty: Advanced.).

Comparison of hemodynamics and root configurations between remodeling and reimplantation methods for valve-sparing aortic root replacement: a pulsatile flow study.

Project description:PurposeTo compare the characteristics of reimplantation (RI) using grafts with sinuses and remodeling (RM) with/without external suture annuloplasty using a pulsatile flow simulator.MethodsPorcine aortic roots were obtained from an abattoir, and six models of RM and RI with sinuses were prepared. External suture annuloplasty (ESA) was performed in the RM models to decrease the root diameter to 22 mm (RM-AP22) and 18 mm (RM-AP18). Valve models were tested at mean pulsatile flow and aortic pressure of 5.0 L/min and 120/80 (100) mmHg, respectively, at 70 beats/min. The forward flow, regurgitation, leakage, backflow rates, valve-closing time, and mean and peak pressure gradient (p-PG) were evaluated. Root configurations were examined using micro-computed tomography (micro-CT).ResultsThe backflow rate was larger in the RM models than in the RI models (RI: 8.56% ± 0.38% vs. RM: 12.64% ± 0.79%; p < 0.01). The RM-AP and RI models were comparable in terms of the forward flow, regurgitation, backflow rates, p-PG, and valve-closing time. The analysis using a micro-CT showed a larger dilatation of the sinus of the Valsalva in the RM groups than in the RI group (Valsalva: RI, 26.55 ± 0.40 mm vs. RM-AP22, 31.22 ± 0.55 mm [p < 0.05]; RM-AP18, 31.05 ± 0.85 mm [p < 0.05]).ConclusionsRM with ESA and RI with neo-sinuses showed comparable hemodynamics. ESA to RM reduced regurgitation.

A remnant mitral subvalvular apparatus mimicking aortic valve vegetation after mitral valve replacement.

Project description:Preservation of the subvalvular apparatus has the merits of postoperative outcomes during mitral valve replacement for mitral regurgitation. We performed mitral valve replacement with anterior and posterior leaflet chordal preservation in a 65-year-old woman. On the 2nd postoperative day, routine postoperative trans-thoracic echocardiography showed an unknown aortic subvalvular mobile mass. We report a case of a remnant mitral subvalvular apparatus detected by echocardiography after chordal preserving mitral valve replacement which was confused with postoperative aortic valve vegetation.

Aortic Valve Thrombosis after Valve-Sparing Aortic Root Replacement and Insertion of an Extracorporeal Left Ventricular Assist Device, Masked by Mediastinal Packing.

Project description:Aortic valve (AV) or aortic root thrombus related to a left ventricular assist device (LVAD) is a relatively uncommon but potentially life-threatening complication. In the present report, we describe a complex case where echocardiographic diagnosis of AV thrombosis was obscured by the presence of mediastinal packing in a patient who underwent valve-sparing aortic root replacement and insertion of the CentriMag™ LVAD for postcardiotomy cardiogenic shock. A large AV thrombus may develop rapidly in patients with LVADs. This case highlights the importance of a careful and thorough transesophageal echocardiography examination in detecting this complication and in altering surgical management.
