- Abstract
Endoaortic balloon occlusion (EABO) and transthoracic cross-clamping have been shown to have comparable safety profiles for aortic occlusion in minimally invasive mitral valve surgery (MIMVS). However, few studies have focused exclusively on the totally endoscopic robotic approach. We sought to compare outcomes for patients undergoing totally endoscopic robotic mitral valve surgery with aortic occlusion via EABO and transthoracic clamping after a period where EABO was unavailable required us to use the transthoracic clamp. Retrospective review identified 113 patients who underwent robotic mitral valve surgery at our facility between 2019 and 2021 with EABO (n = 71) or transthoracic clamping (n = 42). Relevant data were extracted and compared. Preoperative characteristics were similar other than a higher rate of coronary artery disease [EABO: 69.0% (49/71) vs clamp: 45.2% (19/42), p = .02] and chronic lung disease [EABO: 38.0% (27/71) vs clamp: 9.5% (4/42), p < .01] in the EABO group. Median percutaneous cardiopulmonary bypass time, operative time, and cross-clamp time were comparable. Similar rates of postoperative bleeding complications were observed, and no aortic complications were observed. One patient in each group underwent conversion to an open approach. 30-day mortality and readmission rates were comparable. EABO and transthoracic clamp were associated with similar bleeding and aortic outcomes, and mortality and readmission rates were comparable at thirty days postoperatively. Our findings support the comparable safety of the two techniques, which is well documented in studies encompassing all MIMVS techniques, within the specific context of the totally endoscopic robotic approach., (© 2023.

- Abstract
Introduction: The robotic platform reduces the invasiveness of cardiac surgical procedures, thus facilitating earlier discharge in select patients. We sought to evaluate the characteristics, perioperative management, and early outcomes of patients who underwent postoperative day 1 or 2 (POD1-2) discharge after robotic cardiac surgery at our institution., Methods: Retrospective review of 169 patients who underwent robotic cardiac surgery at our facility between 2019 and 2021 identified 57 patients discharged early on POD1 (n = 19) or POD2 (n = 38) and 112 patients who underwent standard discharge (POD3 or later). Relevant data were extracted and compared., Results: In the early discharge group, median patient age was 62 [IQR: 55, 66] (IQR = interquartile range) years, and 70.2% (40/57) were male. Median Society of Thoracic Surgeons predictive risk of mortality score was 0.36 [IQR: 0.25, 0.56] %. The most common procedures performed were mitral valve repair [66.6%, (38/57)], atrial mass resection [10.5% (6/57)], and coronary artery bypass grafting [10.5% (6/57)]. The only significant differences between the POD1 and POD2 groups were shorter operative time, higher rate of in-operating room extubation, and shorter ICU length of stay in the POD1 group. Lower in-hospital morbidity and comparable 30-day mortality and readmission rates were observed between the early and standard discharge groups., Conclusions: POD1-2 discharge after various robotic cardiac operations afforded lower morbidity and similar 30-day readmission and mortality rates compared to discharge on POD3 or later. Our findings support the feasibility of POD1-2 discharge after robotic cardiac surgery for patients with low preoperative risk, an uncomplicated postoperative course, and appropriate postoperative management protocols., (Copyright © 2023 Elsevier Inc.

- Abstract
Objective: Barbed nonabsorbable sutures have been widely adopted for tissue closure in noncardiac robotic surgery to improve intraoperative efficiency. Here, we examine the profile in robotic mitral valve repair (rMVR), which utilized barbed nonabsorbable sutures. To our knowledge, this is the first report to describe clinical outcomes for rMVR with barbed nonabsorbable sutures., Methods: A retrospective review identified 90 patients who underwent rMVR using barbed nonabsorbable sutures at our center between 2019 and 2021. The primary outcome measure was dehiscence, while other relevant outcomes included 30-day readmission and 30-day mortality., Results: In addition to fixation of the mitral annuloplasty band, barbed nonabsorbable sutures were employed commonly in concomitant pericardiectomy closure (100.0%, 90 of 90), atriotomy closure (100.0%, 90 of 90), and left atrial appendage closure (if eligible; 98.8%, 83 of 84). One patient who underwent mitral valve annuloplasty using only barbed nonabsorbable suture required reoperation for annuloplasty ring dehiscence. Immediate postoperative ring dehiscence was not observed in any patients after the routine reinforcement of barbed nonabsorbable sutures with everting pledgeted polyester sutures, and no additional patients required reoperation for suture-related complications. Clinical signs of dehiscence were not observed after pericardiectomy, atriotomy, or left atrial appendage closure with barbed nonabsorbable sutures. The 30-day readmission rate was 3.3% (3 of 90), and 30-day mortality was 0% (0 of 90)., Conclusions: These data suggest the initial feasibility of barbed nonabsorbable sutures in robotic cardiac surgery, specifically within rMVR. Further research is necessary to explore the long-term safety and efficacy profile of such approach.

- Abstract
Objective: Prior studies have demonstrated robotic excision of cardiac tumors as a safe and effective treatment option. The procedure is performed with five incisions: three robotic arm ports, one atrial retractor port, and one working port. We report our unique initial experience in robotic tumor removal. To our knowledge, this is one of the first reports demonstrating cardiac myxoma and fibroelastoma removal with use of exclusively 8-mm ports., Methods: All data for robotic cardiac tumor resection at our institution from June 2019 to December 2021 were retrospectively collected; 18 cases were included, including 13 cardiac myxomas and five fibroelastomas. Baseline demographics, intraoperative characteristics, and surgical outcomes were recorded. Descriptive statistics were calculated; continuous variables were reported as median [interquartile range], and categorical variables were reported as percentages., Results: Median patient age was 64 [55, 70] years old. The cohort consisted of primarily female (67%) and white (83%) patients. Median body mass index was 26.3 [23.0, 31.5] kg/m
2 . 11% of patients were current tobacco users and 50% had hypertension. All patients underwent myxoma or fibroelastoma removal with the use of five 8-mm robotic ports. Each patient underwent percutaneous cannulation via the femoral arteries. Aortic occlusion was achieved via an endoaortic balloon (67%) or transthoracic cross-clamp (33%). Cross-clamp time was 30 [26, 41] minutes. Concomitant procedures performed during myxoma removal included patent foramen ovale closure (28%), mitral valve repair (8%), left atrial appendage closure (8%), Cox-maze procedure (6%), and coronary artery bypass grafting (6%). All cardiac tumors were packaged with use of the endo-bag and subsequently removed through the working port. Maximal myxoma and fibroelastoma diameters were 2.5 [1.7, 3.5] and 0.6 [0.4, 0.7] cm, respectively. Procedural cardiopulmonary bypass time was 77 [65, 84] minutes. No intraoperative mortality, reoperation for bleeding, or postoperative cardiac issues were recorded. One in-hospital mortality occurred as the result of a thrombotic event in the context of a hypercoagulable state unrelated to the patient's operation. No other mortalities were observed at 30 days. Hospital length of stay was 4.5 [3.0, 7.8] days., Conclusions: In our study, the robotic platform facilitated safe and effective cardiac tumor excision. Our results highlight the efficacy of 8-mm port sizing and the concurrent use of other minimally invasive techniques, including percutaneous cannulation, in this patient population. In general, patients prefer the least invasive treatment option available. Our findings emphasize the importance of training cardiac surgeons to perform robotic procedures using the least invasive means possible to provide patients with various options for their treatment., (© 2022 Wiley Periodicals LLC.)- Published

- Abstract
Background: Percutaneous axillary artery cannulation for cardiopulmonary bypass (CPB) offers a novel alternate approach to mechanical circulatory support for patients with contraindications to femoral perfusion. To our knowledge, this has not yet been reported in minimally invasive cardiac surgery (MICS)., Aim: We aim to highlight our experience using percutaneous axillary artery cannulation to safely facilitate CPB for minimally invasive cardiac surgery MICS., Methods: Four patients who underwent robotic cardiac surgery utilizing the axillary artery for percutaneous cannulation between November 2019 and August 2021 at a single center were identified and included in the analysis. Preoperative, intraoperative, and postoperative data were collected and analyzed to support this case series., Results: There were no perioperative hematomas, brachial plexus injuries, or neurovascular injuries. Within 30-days postoperatively there was no mortality, vessel injury, stroke, new onset atrial fibrillation, or other life-threatening bleeding., Conclusion: Percutaneous cannulation of the axillary artery is a novel and promising CPB modality for robotic cardiac surgery in patients with extensive peripheral and aortic atherosclerotic disease., (© 2022 Wiley Periodicals LLC.)

- Abstract
Background: Robotic surgery has gained popularity over the past two decades due to the benefits related to smaller surgical incisions, enhanced technical dexterity and better intraoperative visualization. We present the Yale experience of the first two hundred totally endoscopic, robotic-assisted mitral valve repair procedures for the treatment of degenerative mitral regurgitation., Methods: We performed a retrospective cohort study of patients undergoing totally endoscopic, robotic-assisted isolated or concomitant mitral valve repair for degenerative mitral regurgitation at Yale-New Haven Hospital from October 2018 to April 2022. Mitral valve repair procedures for rheumatic or secondary functional mitral regurgitation and planned robotic-assisted mitral valve replacement cases were excluded., Results: Two hundred consecutive procedures were performed. The median age was 65 years (interquartile range, 58-73 years). Six patients (3.0%) had a history of mediastinal radiation, four patients (2.0%) had previous cardiac surgery, and one patient (0.5%) had cardiac dextroversion. Median cardiopulmonary bypass and aortic cross-clamp times were 122 and 79 minutes, respectively. Femoral vessel cannulation was performed percutaneously in 57 (28.5%) patients with no major access-site related complication. Aortic cross-clamping was performed with the endoaortic balloon occlusion device in 151 (75.5%) patients. No conversions to sternotomy occurred. Satisfactory repair was achieved in 100% of cases, with 184 (92.0%) and 16 (8.0%) of patients having trace/none or mild residual mitral regurgitation, respectively. Forty-two patients (21.0%) underwent concomitant Cox-maze procedure and 25 patients (12.5%) underwent concomitant tricuspid valve repair. Thirty-day mortality rate was 0.5%, with an observed-to-expected ratio of 0.53. Two patients (1.0%) underwent re-exploration for bleeding, one had early postoperative stroke (0.5%), five developed pneumothorax (2.5%) and two required dialysis for acute renal failure (1.0%). The median length of hospital stay was four days., Conclusions: Excellent short-term outcomes can be achieved in experienced centers for the treatment of degenerative mitral regurgitation with a totally endoscopic, robotic-assisted approach., Competing Interests: Conflicts of Interest: MK: physician proctor and a member of the medical advisory board for JOMDD, physician proctor for Peter Duschek, speakers’ honoraria from Medtronic and Terumo.

- Abstract
Background: Mitral valve repair durability currently plays a key role in operative decision making and in defining optimal surgical practice. However, mitral valve durability outcomes measures are not captured by national registries and limited to centers that publish their outcomes. In this study, we aim to describe the scope of institutions represented by reports describing durability outcomes after mitral valve repair within the contemporary literature., Methods and Results: A scoping review of the literature was performed to extract abstracts potentially reporting mitral valve operation outcomes published between 2000-2019. 370 full text articles reporting mitral valve durability outcomes by either reoperation rate or rate of recurrent mitral regurgitation met criteria for analysis. Study characteristics including case volume, country and institution of origin, and surgeon volume were extracted and used to calculate the proportion of total cases in the top 3, 5, and 10 represented countries and institutions by the sum of reported mitral valve repairs described. The top 5 of 21 countries represented 78.9% of the mitral valve repair cases described. The top 3 most represented institutions described 20,120 (37.3%) of all mitral valve repairs in 58 (33.9%) single-center studies., Conclusion: Published mitral valve repair durability data must be interpreted with caution when used to derive policies and practice recommendations that govern the cardiovascular community at large., (© 2022 Wiley Periodicals LLC.)

- Abstract
Background and Aim: In 2011, the Accreditation Council for Graduate Medical Education (ACGME) restricted the first-year residents' duty-hour to less than 16-hour shifts, decreased the maximum shift duration for senior residents, and increased minimum time off after on-call duties. Whether these changes may have impacted the outcomes in cardiac surgery remains unclear., Methods: We performed a difference-in-difference analysis of the New York State Cardiac Surgery Reporting System data in 2004-2006 (before the duty-hour policies change) and 2014-2016 (after the change). We evaluated differences in 30-day risk-adjusted mortality rates (RAMR) in coronary artery bypass grafting (CABG) and valve surgeries, stratifying data by hospital type: teaching hospitals (TH) versus nonteaching hospitals (NTH). NTH served as the control not affected by the duty-hour policies., Results: (1) The overall surgical volume for CABG surgery has decreased over time (37,645-24,991), while the volume for valve surgery remained similar (20,969-21,532); (2) TH had better short-term outcomes for CABG procedures during 2014-2016 (median RAMR: 1.01% vs. 1.55% in TH vs. NTH, respectively; p = .025) as well as for valve procedures during both 2004-2006 (5.16% vs. 7.49%, p = .020) and 2014-2016 (2.59% vs. 4.09%, p = .033); (3) at difference-in-difference analysis, trainees' duty-hour regulations were not associated with worsening short-term outcomes in both CABG (p = .296) and valve (p = .651) procedures performed in TH., Conclusion: The introduction of the 2011 trainees' duty-hour regulations was not associated with worse short-term outcomes for CABG and valve surgery performed in the State of NY by TH., (© 2021 Wiley Periodicals LLC.)

- Abstract
Introduction: Robotic mitral valve surgery has developed for more than 20 years. The main purpose of robotic assistance is to use multiwristed instruments for surgical endothoracic maneuvers on the mitral valve without opening the chest. The surgeon controls the instruments remotely from a console but is virtually immersed into the operative field., Areas Covered: This review outlines indications and contraindication for the procedure. Intra- and postoperative results as available in the literature are reported. Further areas focus on the technological development, advances in surgical techniques, training methods, and learning curves. Finally we give an outlook on the potential future of this operation., Expert Opinion: Robotic assistance allows for the surgically least invasive form of mitral valve operations. All variations of robotic mitral valve repair and replacement are feasible and indications have recently been broadened. Improved dexterity of instrumentation, 3D and HD vision, introduction of a robotic left atrial retractor, and adjunct technology enable most complex forms of minimally invasive mitral valve interventions through ports on the patient's right chest wall. Application of robotics results in significantly reduced surgical trauma while maintaining safety and outcome standards in mitral valve surgery.

- Abstract
Objective: Bicuspid aortic valve (BAV) represents 2 cusps oriented along a spectrum of equal (180°/180°) or unequal (150°/210°) leaflet surface area distribution along the aortic annular plane. We have taken the approach of respecting the native geometric orientation of the repaired BAV leaflets when creating the aortic neoroot during valve-sparing root reimplantation (VSRR) procedures. We investigated midterm outcomes with this 2-prong approach for VSRR in BAV syndrome., Methods: Of 72 patients in a prospectively maintained BAV repair database, 68 met inclusion criteria: 36 patients had 180°/180° neoroot geometry, and 32 patients had 150°/210° orientation. A multivariate ordinal logistic mixed effects model was performed to study parameters associated with recurrent AI greater than 2+., Results: Preoperative parameters were similar between 180°/180° and 150°/210° groups, except for greater incidence of AI 4+ in the latter (50.0% [n = 16] vs 8.3% [n = 3]; P < .001). Postoperatively, stroke, renal failure, reoperation for bleeding, and pacemaker rates were 0 in the entire cohort. In-hospital/30-day mortality in the entire cohort was 1.5% (n = 1). Multivariate ordinal logistic mixed effects model showed that preoperative AI greater than 3+ (odds ratio, 0.4; P = .46) and geometric orientation of the aortic neoroot (odds ratio, 3.8; P = .25) were not significantly associated with recurrence of AI greater than 2+., Conclusions: Respecting BAV geometry for VSRR neoroot creation yields excellent midterm outcomes and may minimize conjoint cusp leaflet stress that may occur in "forcing" a 150°/210° type I BAV into a 180°/180° neoroot., (Copyright © 2019.

- Abstract
Background: In bicuspid aortic valve patients with nonaneurysmal root (<45 mm) and severe aortic insufficiency (AI), external subannular aortic ring (ESAR) is being increasingly utilized for annular stabilization, compared with traditional subcommissural annuloplasty (SCA). To this date, there is no comparative study assessing functional equivalence or superiority of ESAR over SCA., Methods: From 2003 to 2017, 139 patients underwent type I bicuspid aortic valve repair, of which 50 patients underwent concomitant SCA and 24 underwent ESAR. Cases with suboptimal echocardiographic imaging were excluded, resulting in 38 patients in the SCA group and 20 patients in ESAR group. Intraoperative transesophageal echocardiography before and after procedure were retrospectively analyzed for 11 parameters in the functional aortic root complex., Results: ESAR patients had larger preoperative annulus (28.3 ± 3.2 mm versus 29.8 ± 3.7 mm, p = 0.1) and left ventricular (LV) outflow tract (28.1 ± 3.5 mm versus 29.8 ± 4.0 mm, p = 0.1) diameters, with greater leaflet prolapse (3.4 ± 1.3 mm versus 4.3 ± 1.3, p = 0.02). In both groups, 100% freedom from AI greater than 1+ was achieved, with significant reduction of vena contracta (-3.0 ± 0.6 mm, p < 0.001; -3.2 ± 0.4 mm, p < 0.001) and level of eccentricity of AI jet (AI angle change: -24.3 ± 6.5 degrees, p = 0.002; -22.3 ± 7.2 degrees, p = 0.01). Reduction in LV dimensions (-7.1 ± 1.2 mm, p < 0.001; -8.9 ± 1.9 mm, p < 0.001), annulus (-3.4 ± 0.4 mm, p < 0.001; -5.1 ± 2.7 mm, p < 0.001), LV outflow tract (-2.3 ± 0.4 mm, p < 0.001; -4.4 ± 0.5 mm, p < 0.001), and degree of leaflet prolapse (-1.6 ± 0.4 mm, p = 0.005; -2.1 ± 0.4 mm, p = 0.001) was achieved in both groups. Comparison of postprocedure outcomes showed improved mean transvalvular gradients in ESAR (11.2 ± 5.7 mm Hg versus 7.1 ± 2.5 mm Hg, p = 0.003), with similar freedom from AI., Conclusions: In addition to providing equivalent and excellent freedom from AI, ESAR also renders a more robust annular reduction than SCA, along with improved transvalvular gradients., (Copyright © 2019 The Society of Thoracic Surgeons.

- Abstract
Introduction: We evaluated the safety profile of a central cardiopulmonary bypass (CPB) cannulation strategy for repair of extent I thoracoabdominal aortic aneurysms (TAAA) with chronic type B dissection in comparison to traditional peripheral CPB cannulation strategies., Methods: Patients undergoing extent I TAAA repair for chronic type B dissection from 2002 to 2011 were retrospectively reviewed. Patients were grouped by their CPB cannulation strategy. Patients in Group I underwent central aortic cannulation (n = 28) through a left thoracotomy incision. The true lumen of the descending thoracic aorta was cannulated using an echocardiogram-guided Seldinger wire technique. The right atrium was directly accessed for venous drainage. In Group II (n = 31), arterial and venous cannulation of the femoral vessels was achieved using a left-sided groin incision. All patients underwent deep hypothermic circulatory arrest for proximal aortic reconstruction., Results: Preoperative aortic dimensions (6.5 ± 0.79 cm in Group I vs 7.0 ± 1.15 cm in Group II p = 0.8) were similar between groups. CPB time (240 ± 37 min in Group I vs 174 ± 68 min in Group II p < 0.01) was significantly higher in the central cannulation group whereas circulatory arrest times (43 ± 5 min Group I vs 37 ± 7 min in Group II p = 0.1) were similar between the two groups. In-hospital 30-day mortality (N = 0, 0% in Group I; N = 2, 6.5% in Group II), stroke (N = 1, 3.5% in Group I; N = 0, 0% in Group II), paraplegia (N = 1, 3.5% in Group I; N = 1, 3.2% in Group II), reoperation for bleeding (N = 1, 3.5% in Group I; N = 1, 3.2% Group II), tracheostomy rate (N = 2, 7% in Group I; N = 3, 9.7% Group II), and mean length of stay (19 days in Group I vs 17 days in Group II) were similar (p > 0.05). Median follow-up was 3.6 ± 2.0 in Group I and 5.6 ± 2.6 years in Group II. Actuarial survival at 5 years was 84.6 % for Group I and 77.6% for Group II (p = 0.52)., Conclusions: Central true lumen cannulation through a left thoracotomy incision for repair of extent I TAAA with chronic type B dissection is an acceptable approach with equivalent early and midterm outcomes compared to more standard femoral cannulation techniques. It may provide a safe alternative cannulation site for patients with diseased femoral vessels., (© 2017 Wiley Periodicals, Inc.)

- Abstract
Background: In patients with a bicuspid aortic valve presenting with aortic insufficiency (AI) and root aneurysm, we assessed whether outcomes with primary cusp repair with root reimplantation were equivalent to the gold standard Bentall procedures., Methods: From 2002 to 2014, 710 patients with bicuspid aortic valve underwent aortic root procedures. Of these, only patients presenting with noncalcified type I bicuspid aortic valve with AI (n = 165) were included to maintain anatomic and physiologic homogeneity between the groups. Aortic stenosis, endocarditis, redo root, and emergency cases were excluded. Patients undergoing valve-sparing root reimplantation (VSRR group, n = 45) were retrospectively compared with those undergoing Bentall root replacement (Bentall group, n = 120)., Results: Patients in the Bentall group were older (52 ± 13 vs 46 ± 12 years; p ≤ 0.01) and had a lower ejection fraction (0.53 ± 0.12 versus 0.58 ± 0.08; p < 0.01), but left ventricular diastolic diameter was similar (58 ± 10 mm versus 57 ± 9 mm; p = 0.5). Thirty-day and in-hospital mortality was zero; in-hospital stroke rate was 0.8% (n = 1) in the Bentall group (0 in the VSRR group; p = 0.54). Permanent pacemaker rate was 6% (n = 7) in the Bentall group (0 in the VSRR group; p = 0.2). On discharge echocardiography, AI grade ≤ 1+ (100%; p = 1) and transvalvular gradients (mean gradient 7 ± 3 versus 6 ± 3 mm Hg; p = 0.14) were similar. Mean follow-up was 7.5 ± 3.2 and 3.4 ± 2.9 years (p < 0.001). There were 14 transient ischemic attacks or stroke events in the Bentall group, and none in the VSRR group. One patient in each group exhibited AI ≥ 3+. Five-year actuarial survival (100% versus 98% ± 2%; p = 0.8) and freedom from aortic reoperation (98% ± 2% versus 100%; p = 0.8) were similar., Conclusions: In patients with bicuspid aortic valve AI with root aneurysm, primary cusp repair with root reimplantation achieves equivalent midterm outcomes compared with Bentall root replacement., (Copyright © 2016 The Society of Thoracic Surgeons.

- Abstract
Background: Transcatheter aortic valve replacement (TAVR) is an established therapy in high-risk patients with severe aortic stenosis. Among patients with reduced left ventricular ejection fraction (LVEF), it is unclear which patients will derive maximal benefit from TAVR., Methods: Clinical and echocardiographic data of patients with severe aortic stenosis and low LVEF (≤50%) who underwent TAVR at a single institution during 2009-2013 were retrospectively analyzed. Patients were divided into 2 groups post-TAVR based on improved LV function (Group A = ΔLVEF ≥ 10%) versus persistent LV dysfunction (Group B = ΔLVEF<10%). Echocardiographic parameters were assessed for their association with LVEF change post-TAVR. Kaplan-Meier analysis was performed to generate survival estimates., Results: Of 382 patients who underwent TAVR, 60 patients had low LVEF, LV function failed to improve ≥10% in 50% of patients following the procedure (Group B). At baseline echocardiograms, Group B had higher LVEF, stroke volume (SV), SV index; and lower E, E/E', and estimated pulmonary arterial systolic pressure (PASP) compared to Group A. Higher mortality was found in Group B compared to the Group A (p = 0.003) with a significantly shorter survival (Group A = 3.3 ± 0.1 years vs Group B = 2.7 ± 0.2 years, p = 0.003). One-year event free survival was 53.3% in Group B compared to 93.3% in Group A, with a stable trend over ensuing years (5-year survival; 53.3% versus 90.0%, p = 0.003)., Conclusions: In patients undergoing TAVR with depressed LV function, those who failed to improve were more likely to have relatively higher LVEF, SV, and SVI; and lower E, E/E', and PASP at baseline. Mortality rates were found to be higher in persistent LV dysfunction group. © 2015 Wiley Periodicals, Inc., (© 2015 Wiley Periodicals, Inc.)

- Abstract
Background and Aim of the Study: An investigation was made as to whether the preoperative aortic annular diameter affects the durability of bicuspid aortic valve (BAV) repair in patients who had undergone concomitant root stabilization with subcommissural annuloplasty (SCA) compared to valve-sparing root reimplantation (VSRR)., Methods: Among a retrospective review of 74 patients who underwent BAV repair between 2005 and 2012,42 had SCA and 32 had VSRR., Results: The preoperative annulus was similar in the two groups (29 +/- 3 mm for SCA; 30 +/- 4 mm for VSRR, p = 0.3). Postoperative aortic insufficiency (AI) grade > or = 1+ was 100%, but five-year freedom from Al grade >1+ was lower in the SCA group (62 +/- 10% versus 92 +/- 6%, p = 0.02). On univariate analysis, a preoperative annulus 28 mm was predictive of recurrent Al grade >1+ in the SCA group (odds ratio 17.1, p = 0.05), but not in the VSRR group (3.31, p = 0.1). Consequently, SCA patients were evaluated by annular diameter 28 mm (n = 26) versus < or = 27 mm (n = 16). Five-year freedom from AI grade >1+ was lower for the 28 mm SCA subgroup (52 +/- 10% versus +/-3 +/- 6%, p = 0.02). Given this difference between the SCA subgroups, Al grade >1+ in the 28 mm SCA subgroup was compared to VSRR patients with annulus 28 mm ( 28 mm VSRR subgroup, n = 23). The five-year freedom from AI grade >1+ was significantly higher in the 28 mm VSRR subgrou+/- (86 +/- 10% versus 52 +/- 10%, p = 0.02), but simila < or = Sr in the 27 27 m< or = SCA and 527 mm VSRR subgroups (93 +/- 6% versus 100%, p = 0.4)., Conclusion: For BAV patients with a preoperative aortic annulus 28 mm, SCA results in inferior midterm outcomes. VSRR or alternative annular stabilization techniques should be considered

- Abstract
Background: Deep hypothermic circulatory arrest (DHCA) with retrograde cerebral perfusion (DHCA group) has traditionally been the cerebral protection strategy during transverse hemiarch aortic reconstruction. Recently, we have adopted moderate hypothermic (≥ 25 °C) circulatory arrest (MHCA) with antegrade cerebral perfusion (MHCA group). We compared the outcomes for these two circulatory arrest management strategies., Methods: From 2008 to 2012, in a concurrent series of 376 patients (DHCA, 301; MHCA, 75) undergoing transverse hemiarch for aortic aneurysm disease, incidences of concomitant root replacement (44% vs 47%, p = 0.8), and aortic valve replacement (29% vs 21%, p = 0.3) were similar, although atherosclerotic aneurysm pathology was present in patients in the MHCA group (71% vs 33%, p < 0.01). Antegrade cerebral perfusion was established via axillary artery or direct innominate artery cannulation. A database was prospectively maintained., Results: MHCA group patients were older (66 ± 11 vs 60 ± 14 years; p < 0.01). Other demographics were similar. Aortic cross-clamp (128 ± 46 vs 163 ± 57 minutes, p < 0.01) and cardiopulmonary bypass (167 ± 49 vs 222 ± 61 minutes, p < 0.01) times were lower in the MHCA group. Transfusion requirements were significantly reduced with MHCA (38% vs 61%, p < 0.01), especially use of fresh frozen plasma and cryoprecipitate. Direct innominate artery cannulation did not result in any vascular or neurologic complication. Postoperative outcomes were similar. In-hospital and 30-day mortality was 1% in both groups. Stroke (0% vs 2%) and hemodialysis rates (0% vs 1%) were also similar., Conclusions: MHCA with antegrade cerebral perfusion yields excellent and equivalent outcomes to DHCA for elective aortic hemiarch reconstruction. MHCA significantly improves intraoperative times and, importantly, reduces transfusion requirements compared with DHCA with a retrograde cerebral perfusion strategy., (Copyright © 2015 The Society of Thoracic Surgeons.

- Abstract
Objective: Valve-sparing root reimplantation (VSRR) in tricuspid aortic valve (TAV) patients is well established, but in bicuspid aortic valve (BAV) patients, it has been less widely adopted. We assessed whether valve type affects midterm outcomes with VSRR., Methods: A retrospective review was performed of 186 patients who underwent an aortic valve-sparing root reimplantation operation between 2004 and 2013. Of these, 129 patients underwent elective VSRR with the David V technique. Outcomes were compared in this cohort by valve type: TAV (n = 89) versus BAV (n = 40)., Results: Demographics were similar in the 2 groups. BAV patients had a higher degree of aortic insufficiency (AI) at presentation (P < .05), and an enlarged preoperative annulus (30 ± 4 vs 28 ± 6 mm, P = .06). All BAV patients required primary leaflet repair (6% in the TAV group; P < .01). Postoperative mortality (0), stroke (0% vs 1%), and pacemaker requirement (0% vs 5%) were similar. Postoperative freedom from AI grade ≥2+ was 100% in the entire cohort, and transvalvular gradients were similar. At follow-up, a 1-year echocardiogram showed higher peak and mean transvalvular gradients in the BAV group (P < .01). One TAV group patient died from an unknown cause. The 5-year actuarial freedom from aortic valve reoperation was 100% versus 97% ± 3% (P = .6). Three patients in the entire cohort have had AI grade >2+ on follow-up (n = 1 in the BAV group; n = 2 in the TAV group)., Conclusions: Even though BAV patients present with higher AI grade and require concomitant primary valve repair, the VSRR David V technique offers excellent midterm outcomes with both the BAV and TAV valve types., (Copyright © 2015 The American Association for Thoracic Surgery.

- Abstract
Background: At our institution, type I bicuspid aortic valve (BAV) patients with aortic insufficiency (AI) who are candidates for valve preservation are stratified into two groups by aortic root pathology: nonaneurysmal root undergoing primary cusp repair+subcommissural annuloplasty (repair group) vs aneurysmal root undergoing primary cusp repair+root reimplantation (reimplantation group). We report outcomes of this surgical reconstructive strategy for the repaired type I BAV., Methods: A retrospective review was performed of 71 patients with a type I BAV undergoing primary valve repair from 2005 to 2012. The repair group (n=40) underwent annular stabilization by subcommissural annuloplasty, and the reimplantation group (n=31) underwent robust annular stabilization provided by root reimplantation., Results: Preoperative characteristics and root anatomy were similar, except for increased root dimensions in the reimplantation group (p<0.001). Mortality, stroke, valve reoperation, and pacemaker requirement were zero in both groups. Postoperative peak (19±10 vs 11±5 mm Hg, p<0.001) and mean gradients (10±5 vs 5±3 mm Hg, p<0.001) favored root reimplantation. Freedom from AI greater than 1+ was 100% in both groups. Mean follow-up was 40 months in the reimplantation group and 38 months in the repair group. At 5 years, overall survival was 100% in both groups. Freedom from aortic reoperation and AI exceeding 2+ were similar in both groups. Freedom from AI exceeding 1+ was significantly better in the reimplantation group (92%±6% vs 62%±10%, p=0.03). The 2-year peak (14±6 vs 19±9 mm Hg, p=0.009) and mean (7±4 vs 11±5 mm Hg, p=0.001) gradients favored root reimplantation., Conclusions: Root stabilization with the reimplantation technique significantly improves the durability of the repaired type I BAV compared with subcommissural annuloplasty. It also provides improved and sustained valve mobility (transvalvular gradients)., (Copyright © 2014 The Society of Thoracic Surgeons. Published by Elsevier Inc. All rights reserved.)

- Abstract
Direct transaortic (TAo) approach for transcatheter aortic valve replacement (TAVR) in patients with symptomatic, severe aortic stenosis (AS) with prohibitive transfemoral access is being increasingly performed. Furthermore, concomitant catheter-based procedures such as percutaneous coronary intervention (PCI) are also being increasingly performed during TAVR. We report a single-stage, catheter-based treatment of both critical AS and descending thoracic aortic aneurysm (DTA) by performing TAVR with concomitant thoracic aortic endovascular repair (TEVAR) through direct TAo access via a minimally invasive partial sternotomy approach. To our knowledge, this is the first report of a "hybrid" TAVR+TEVAR., (Copyright © 2014 The Society of Thoracic Surgeons. Published by Elsevier Inc. All rights reserved.)

- Abstract
Objectives: Primary cusp repair + aortic root reimplantation in bicuspid aortic valve (BAV) disease presenting with root aneurysm with aortic insufficiency (AI) is an effective surgical treatment. We assessed whether the geometric orientation of the repaired BAV into its reimplanted neoroot affects outcomes-180°/180° orientation was compared with the 150°/210° orientation., Methods: From 2005 to 2012, 66 BAV repairs were performed. This is a retrospective review of all types of Ib/II BAV AI patients undergoing root reimplantation (n = 26) at two different geometric orientations: 180°/180° (n = 11) vs 150°/210° (n = 15). In the 180°/180° group, reimplantation into the neoroot was such that both conjoint and non-conjoint cusps occupied 180° of the annular circumference. In the 150°/210° group, the repaired valve was configured to the more typical native orientation of a type I BAV: the non-conjoint cusp occupied 150°, and the conjoint cusp occupied 210° of the annular circumference., Results: Preoperative characteristics were similar in both groups. In-hospital mortality, stroke, reoperation, renal failure and pacemaker rates were zero in both groups. No patient left the operating room with >1+ AI and one had a peak gradient >20 mmHg. Transvalvular gradients were higher in the 180°/180° group, but not significant (P > 0.05). M.ean follow-ups for the 180°/180° and 150°/210° group were 48 and 33 months, respectively. Actuarial freedom from AI >2+ at 5 years was 100% in both groups. Freedom from AI >1+ at 5 years was 90 ± 10% in the 150°/210° group and 86 ± 13% in the 180°/180° group (P = 0.71). Freedom from peak gradient >20 mmHg was 80% (n = 8) in the 180°/180° group and 100% in the 150°/210° group at 1-year follow-up. Transvalvular gradients were higher in the 180°/180° group (16 ± 8 vs 10 ± 4 mmHg, P = 0.02; 9 ± 3 vs 5 ± 3 mmHg, P = 0.01). Five-year actuarial survival and freedom from aortic reoperation have remained at 100% in the entire cohort., Conclusion: Cusp repair + root reimplantation for BAV type Ib/II AI can be safely performed at either geometric orientation. Conceptually, 150°/210° orientation respects the natural type I BAV anatomy with regard to cusp surface area and leaflet insertion perimeter. The 180°/180° group may have higher transvalvular gradients and smaller coaptation zones than the 150°/210° group. Further follow-up may reveal the superiority of one geometric orientation over the other.

- Abstract
Introduction: Allograft use has increased recently with the rising use of allograft materials in breast surgery. There are few data that compare the performance of the various allograft materials in this application, despite marketing efforts by the manufacturers to present one allograft material as superior to another. Phalloplasty is a procedure that uses allografts for penis girth augmentation. Preparation of these grafts differs with each manufacturer. We report our experience with 3 different types of allografts for this procedure. This allows for the comparison of these materials in their performance with a single model., Methods: Forty-seven patients who underwent penis girth enhancement with allograft material were reviewed. All patients underwent circumferential grafting to the shaft of the penis at the level of Buck's fascia. Graft materials included AlloDerm (n = 9), Belladerm (n = 20), and Repriza (n = 21). Charts were reviewed for material type, presence and type of infection, wound exposure, and graft loss with attention to the type of allograft material that was used., Results: Follow-up ranged from 1 to 120 months with an average of 11.25 months. Infection, defined as an open wound with graft exposure, occurred in 20 (42%) of 47 patients. Of these, graft exposure only occurred in 17 (36%) patients, whereas 3 (6%) patients sustained total graft loss. Graft exposure or loss occurred in 3 patients who had AlloDerm, 9 patients with Belladerm, and 8 patients with Repriza. No patients with AlloDerm sustained graft loss, whereas 2 patients with Belladerm and 1 patient with Repriza sustained graft loss. There were no statistical differences among these graft types with regard to infection or graft loss., Conclusions: Three different brands of allograft material were used in 1 surgical procedure and followed up for their performance with regard to exposure and infection. In this model, there is no difference in the rate of infection in these materials despite their different methods of preparation. Implications of this fact are discussed in the approach surgeons should consider when using these materials.

- Abstract
Management of aortic arch aneurysm and dissection continues to evolve as endovascular options play an increasing role in treating thoracic aortopathies. Although conventional open treatment of aortic arch disease with total arch replacement still remains the gold standard, in patients with old age and/or high comorbid disease index, there is significant associated morbidity and mortality. The hybrid arch procedure, which aims to minimize cardiopulmonary bypass and circulatory arrest times, is a particularly appealing surgical option in this cohort of patients. The hybrid arch concept essentially entails three main principles: (I) open debranching of the great vessels; (II) creation of proper proximal (zone 0 landing) and distal landing zones, and; (III) concomitant or delayed endovascular stent grafting of the aortic arch. The classification scheme for hybrid arch debranching procedures is based on the extent of proximal and distal landing zone reconstruction required, and thus the need and extent of cardiopulmonary bypass and circulatory arrest management strategies to be employed. In this illustrated article, we describe the details of the type II hybrid arch debranching procedure, where the ascending aorta and aortic arch pathology is typically treated by reconstruction of ascending aorta ﹢ arch vessel debranching, with concomitant antegrade stent grafting of the aortic arch.
