RESUMEN
BACKGROUND: Operative mortality for type A aortic dissection is still 10-20% at centers of excellence. Additionally, 10-20% are not considered as viable candidates for open surgical repair and not offered life-saving emergency surgery. ARISE is a multicenter investigation evaluating the novel GORE® Ascending Stent Graft (ASG; Flagstaff, AZ). OBJECTIVE: The purpose of this study is to assess early feasibility of using these investigational devices to treat ascending aortic dissection. METHODS: This a prospective, multicenter, non-randomized, single-arm study that enrolls patients at high surgical risk with appropriate anatomical requirements based on computed tomography imaging at 7 of 9 US sites. Devices are delivered transfemorally under fluoroscopic guidance. Primary endpoint is all-cause mortality at 30 days. Secondary endpoints include major adverse cardiovascular and cerebrovascular events (MACCE) at 30 days, 6 months, and 12 months. RESULTS: Nineteen patients were enrolled with a mean age of 75.7 years (range 47-91) and 11 (57.9%) were female. Ten (52.6%) had DeBakey type I disease, and the rest were type II. Sixteen (84.2%) of the patients were acute. Patients were treated with safe access, (7/19 (36.8%) percutaneous, 10/19 (52.6%) transfemoral, 2/19 (10.5%) iliac conduit), delivery, and deployment completed in all cases. Median procedure time was 154 mins (range 52-392) and median contrast used was 111 mL (range 75-200). MACCE at 30 days occurred in 5 patients including mortality 3/19 (15.8%), disabling stroke in 1/19 (5.3%), and myocardial infarction in 1/19 (5.3%). CONCLUSION: Results from the ARISE early feasibility study of a specific ascending stent graft device to treat ascending aortic dissection are promising.

BACKGROUND: Transcatheter aortic valve-in-valve implantation (ViV-TAVI) has emerged in recent years as a safe alternative to redo surgery in high-risk patients. Although early results are encouraging, data beyond short-term outcomes are lacking. Herein, we aimed to assess the 2-year outcomes after ViV-TAVI. METHODS: Patients undergoing ViV-TAVI for degenerated surgical valves between 2013 and 2019 at the Cleveland Clinic were reviewed. The coprimary endpoints were all-cause mortality and congestive heart failure (CHF) hospitalizations. We used time-to-event analyses to assess the primary outcomes. Further, we measured the changes in transvalvular gradients and the incidence of structural valve deterioration (SVD). RESULTS: One hundred and eighty-eight patients were studied (mean age = 76 years; 65% males). At 2 years of follow-up, all-cause mortality and CHF hospitalizations occurred in 15 (8%) and 28 (14.9%) patients, respectively. On multivariable analysis, the postprocedural length of stay was a significant predictor for both all-cause mortality (hazard ratio [HR] = 1.1; 95% confidence interval [CI]: 1.01, 1.19) and CHF hospitalization (HR = 1.16; 95% CI: 1.07, 1.27). However, the internal diameter of the surgical valve was not associated with significant differences in both primary endpoints. For hemodynamic outcomes, nine patients (4.8%) developed SVD. The mean and peak transvalvular pressure gradients remained stable over the follow-up period. CONCLUSION: ViV-TAVI for degenerated surgical valves was associated with favorable 2-year clinical and hemodynamic outcomes. Further studies are needed to better understand the role of ViV-TAVI as a treatment option in the life management of aortic valve disease.

Redo cardiac surgery can present a unique set of challenges even to the experienced surgeon. Although outcomes have steadily improved in the modern era; if an intraoperative adverse event occurs, there is a 5% incidence of mortality and 19% incidence of myocardial infarction, stroke or death. Overall, the modern incidence of mortality at reoperation varies but be segregated into low and higher risk cohorts depending on the planning computed tomography imaging and risk to substernal structures on re-entry. Patients with ascending aortic or root pseudoaneurysms represent a particularly difficult subset of high-risk patients requiring reoperative cardiac surgery due to the danger of exsanguination and air embolization. The gold standard for management of such cases remains the use of deep hypothermic circulatory arrest (DHCA) to achieve safe re-entry in such cases however this can result in unpredictable DHCA duration depending on the degree of pericardial adhesions. We report a case of aortic pseudoaneurysm in a patient with patent coronary grafts managed using an endoballoon precisely positioned relative to the proximal anastomoses resulting in a safe surgical re-entry and shorter DHCA time.

PURPOSE OF REVIEW: In the present review, we discuss the role of CT imaging in the management of aortic dissection, with a particular emphasis on endovascular treatment considerations. RECENT FINDINGS: Computed tomography imaging is a fundamental tool in the diagnosis and management of acute and chronic aortic dissection. Its diagnostic accuracy and high resolution contribute to and guide operative strategy. Persistent high mortality for patients who develop aortic dissections suggests a need for innovative diagnostic and treatment strategies. In the recent era, considerable advances have been made in computed tomography (CT) image acquisition, processing, and analysis as well as endovascular technologies with expanded roles in the treatment of aortic diseases.

BACKGROUND: A survival benefit for obese patients has been observed in various medical and surgical populations. We examined the effect of obesity on outcomes after cardiac surgery from a large national database. METHODS: A total of 6 648 334 adult patients were identified from the Nationwide Inpatient Sample who underwent cardiac surgery between 1998 and 2011, of who 598 450 were obese. Multivariable regression analysis and propensity score matching were used for comparisons of outcomes and costs. RESULTS: In-hospital mortality was 2.0% for obese patients versus 2.3% for non-obese patients (odds ratio [OR] 0.89, 95% confidence interval [CI] 0.84, 0.94). Obese patients were at increased risk for acute renal failure (OR, 1.20; CI, 1.16, 1.23) and wound infection (OR, 1.29; CI, 1.18, 1.40), but less likely to require blood transfusion (OR, 0.96; CI, 0.94, 0.98). Mean length of stay was the same (8.7 days), with greater mean total charges for obese patients ($103 645 vs $101 763, P < 0.001). CONCLUSION: Obesity is associated with lower in-hospital mortality rates, but a higher incidence of acute renal failure and wound infections.

A patient with residual thoracoabdominal aortic aneurysm and chronic dissection extending into the branch iliac arteries underwent staged open and endovascular repair. Open repair of the reno-visceral segment was performed with an "elephant trunk" trunk graft placed distally into a 12-cm infra-renal aorta. One month later, the patient underwent a successful completion endovascular aortic repair. This case demonstrates the utility of combining traditional and endovascular surgery to manage complex aortic pathologies.

OBJECTIVE: To characterize residual aortic regurgitation (AR), identify its risk factors, and evaluate outcomes following aortic root replacement with aortic valve reimplantation. METHODS: From 2002 to 2020, 756 patients with a tricuspid aortic valve underwent elective reimplantation for aortic root aneurysm. AR on transthoracic echocardiograms before hospital discharge was graded as mild or greater. Machine learning was used to identify risk factors for residual AR and subsequent aortic valve reoperation. RESULTS: Sixty-five patients (8.6%) had mild (58 [7.7%]) or moderate (7 [0.93%]) residual postoperative AR. They had more severe preoperative AR (38% vs 12%; P < .0001), thickened cusps (7.7% vs 2.2%; P = .008), aortic valve repair (38% vs 23%; P = .004), and multiple returns to cardiopulmonary bypass for additional repair (11% vs 3.3%; P = .003) than those without AR. Predictors of residual AR were severe preoperative AR, smaller aortic root graft, and concomitant cusp repair. At 10 years, patients with versus without residual AR had more moderate or severe AR (48% vs 7.0%; P < .0001) and freedom from reoperation was worse (89% vs 98%; P < .0001). Residual AR was a risk factor for early reoperation. Concomitant coronary bypass, lower body mass index, and lower ejection fraction were risk factors for late reoperation. Ten-year survival was similar among patients with and without residual AR (97% vs 93%; P = .43). CONCLUSIONS: Residual AR after elective reimplantation of a tricuspid aortic valve for aortic root aneurysm is uncommon. Patients with severe preoperative AR and those who undergo valve repair have higher risk for residual AR, which can progress and increase risk of aortic valve reoperation.

Objective: Anterior mitral anular calcification, particularly in radiation heart disease, and previous valve replacement with destroyed intervalvular fibrosa are challenging for prosthesis sizing and placement. The Commando procedure with intervalvular fibrosa reconstruction permits double-valve replacement in these challenging conditions. We referenced outcomes after Commando procedures to standard double-valve replacements. Methods: From January 2011 to January 2022, 129 Commando procedures and 1191 aortic and mitral double-valve replacements were performed at the Cleveland Clinic, excluding endocarditis. Reasons for the Commando were severe calcification after radiation (n = 67), without radiation (n = 43), and others (n = 19). Commando procedures were referenced to a subset of double-valve replacements using balancing-score methods (109 pairs). Results: Between balanced groups, Commando versus double-valve replacement had higher total calcium scores (median 6140 vs 2680 HU, P = .03). Hospital outcomes were similar, including operative mortality (12/11% vs 8/7.3%, P = .35) and reoperation for bleeding (9/8.3% vs 5/4.6%, P = .28). Survival and freedom from reoperation at 5 years were 54% versus 67% (P = .33) and 87% versus 100% (P = .04), respectively. Higher calcium score was associated with lower survival after double-valve replacement but not after the Commando. The Commando procedure had lower aortic valve mean gradients at 4 years (9.4 vs 11 mm Hg, P = .04). After Commando procedures for calcification, 5-year survival was 60% and 59% with and without radiation, respectively (P = .47). Conclusions: The Commando procedure with reconstruction of the intervalvular fibrosa destroyed by mitral anular calcification, radiation, or previous surgery demonstrates acceptable outcomes similar to standard double-valve replacement. More experience and long-term outcomes are required to refine patient selection for and application of the Commando approach.
RESUMEN
BACKGROUND: Multisegment thoracic aortic disease typically requires total aortic arch replacement, affects a heterogenous population, and carries a high risk even at centers of excellence. Risk has been associated with the duration of operation and complexity of repair. A novel branched stented anastomosis frozen elephant trunk repair (B-SAFER) technique has been developed at our center and is currently being studied as a physician-sponsored investigation device exemption (PS-IDE). OBJECTIVE: This study aimed to assess the early safety of using this investigational technique to treat the proximal aorta in subjects with aortic disease involving multiple segments. METHODS: This prospective, single center, nonrandomized study enrolled patients undergoing B-SAFER for acute aortic syndrome (n = 73), aortic aneurysm with chronic aortic dissection (n = 68), degenerative aortic aneurysm (n = 33), or congenital aortic arch disease (n = 4). Devices are delivered antegrade under hypothermic circulatory arrest, and the arch reconstruction is performed as a single anastomosis single stent (SASS; n = 70), single anastomosis multiple stent (SAMA; n = 68), multiple anastomosis single stent (MASS; n = 21), or multiple anastomosis multiple stent (MAMS; n = 16) reconstruction. The primary safety endpoints were operative mortality, disabling stroke, and paraparesis/paralysis. RESULTS: Between May 27, 2021, and December 31, 2022, 178 patients underwent B-SAFER in the configurations and for the indications as described above. The median patient age was 65 years (range, 21 to 85 years), and 52 (29%) were female. The median cardiopulmonary bypass time was 188 minutes (interquartile range [IQR], 155 to 226 minutes), and 97% of the patients underwent repair with antegrade brain perfusion for a median of 46 minutes (IQR, 38 to 61 minutes). Operative mortality occurred in 10 patients (5.6%, including 6 [8.2%] with acute dissection, 2 [2.9%] with chronic dissection, 2 [6.1%] with degenerative aneurysm, and 0 with a congenital disorder), disabling stroke in 5 patients (2.9%), and paraparesis in 1 patient. Other serious complications included respiratory failure (n = 20; 11.4%) and acute kidney injury (n = 18; 10%). Thirty-two patients (18%) had undergone second-stage repairs (28 endovascular and 4 open), with 1 operative mortality after that procedure due to distal rupture. Estimated survival was 95% at 30 days, 88% at 90 days, 84% at 6 months, and 79% at 1 year. One-year survival differed by indication (72% for acute dissection, 91% for chronic dissection, 71% for degenerative aneurysm, and 100% for congenital disorders). CONCLUSIONS: The B-SAFER technique for total arch replacement in a complex cohort of patients with various indications for surgery is a safe and reproducible operation, as demonstrated by the early results from a very inclusive PS-IDE study. Further follow-up and analysis will help refine the technique. Novel devices to perform this procedure should be developed.
RESUMEN
OBJECTIVE: The durability of reimplanted myxomatous aortic valves in root replacements for patients with connective tissue disorders (CTD) is unclear; therefore, we sought to evaluate the long-term resilience of these repairs. METHODS: From January 1980 to January 2020, 214 patients with CTD and 645 without CTD underwent primary, elective aortic valve reimplantation operations at Cleveland Clinic. The CTD cohort included 164 (77%) with Marfan, 23 (11%) with Loeys-Dietz, and 7 (3.3%) with Ehlers-Danlos CTD. We accounted for differing patient characteristics between the groups by propensity score matching to compare outcomes, yielding 96 matched pairs. Longitudinal echocardiographic measures were compared using nonlinear mixed effects models. RESULTS: In the CTD cohort, there were no operative mortalities (30-day or in-hospital), 1 (0.47%) stroke, and 1 (0.47%) early in-hospital reoperation for valve dysfunction. Ten-year prevalence of no aortic regurgitation was 86%, mild 11%, and moderate 3%. Ten-year freedom from reoperation was 97%. In propensity matched cohorts, there were no significant differences in in-hospital outcomes, longitudinal aortic regurgitation and mean gradient, risk of reoperation on the aortic valve, or risk of late death. CONCLUSIONS: Aortic valve reimplantation is a durable operation in patients with CTD and root aneurysms. These patients do not experience early degeneration of their reimplanted aortic valves.

OBJECTIVES: To describe patient characteristics and indications for surgical intervention, reoperation, and outcomes in patients with actin alpha-2 (ACTA2) variants. METHODS: A single-center retrospective cohort study with prospective follow-up was performed for 38 patients with an ACTA2 variant. RESULTS: From 1999 to 2020, 26 (70%) patients underwent surgery; 11 remain under surveillance (mean follow-up, 7.5 ± 5 years). Median age at index operation was 42 (range, 10-69) years, with 4 pediatric cases. Thoracic aortic aneurysm was present in 19 (73%) patients (mean adult max diameter, 5.2 ± 0.8 cm; pediatric z score, 10.7 ± 5.4). Aortic dissection was present in 13 (50%) patients, with 4 (15%) having type A dissection. Operations included replacement of the aortic root in 16 (17%), ascending aorta in 20 (77%), and aortic arch in 14 (54%) patients. Four (15%) patients had coronary artery disease, and 2 (7.7%) underwent concomitant coronary artery bypass grafting. There was no operative mortality, stroke, reoperation for bleeding, or dialysis-dependent renal failure; One (3.8%) patient developed acute on chronic kidney injury. Three patients (12%) required prolonged ventilation. Eleven (42%) patients underwent 26 reoperations, median time 45 (range, 4-147) months, including 5 open thoracoabdominal aneurysm repairs. CONCLUSIONS: Patients with ACTA2 variants frequently develop aortic aneurysm and are at risk of aortic dissection and coronary artery disease. However, age at diagnosis and symptoms at presentation are highly variable. Multiple operations are often required for disease management, particularly after dissection. Close monitoring and timely intervention are important in mitigating disease progression and improving outcomes.
RESUMEN
OBJECTIVES: A better surgical approach for acute DeBakey type I dissection has been sought for decades. We compare operative trends, complications, reinterventions and survival after limited versus extended-classic versus modified frozen elephant trunk (mFET) repair for this condition. METHODS: From 1 January 1978 to 1 January 2018, 879 patients underwent surgery for acute DeBakey type I dissection at Cleveland Clinic. Repairs were limited to the ascending aorta/hemiarch (701.79%) or extended through the arch [extended classic (88.10%) or mFET (90.10%)]. Weighted propensity score matched established comparable groups. RESULTS: Among weighted propensity-matched patients, mFET repair had similar circulatory arrest times and postoperative complications to limited repair, except for postoperative renal failure, which was twice as high in the limited group [25% (n = 19) vs 12% (n = 9), P = 0.006]. Lower in-hospital mortality was observed following limited compared to extended-classic repair [9.1% (n = 7) vs 19% (n = 16), P = 0.03], but not after mFET repair [12% (n = 9) vs 9.5% (n = 8), P = 0.6]. Extended-classic repair had higher risk of early death than limited repair (P = 0.0005) with no difference between limited and mFET repair groups (P = 0.9); 7-year survival following mFET repair was 89% compared to 65% after limited repair. Most reinterventions following limited or extended-classic repair underwent open reintervention. All reinterventions following mFET repair were completed endovascularly. CONCLUSIONS: Without increasing in-hospital mortality or complications, less renal failure and a trend towards improved intermediate survival, mFET may be superior to limited or extended-classic repair for acute DeBakey type I dissections. mFET repair facilitates endovascular reintervention, potentially reducing future invasive reoperations and warranting continued study.

Objective: The study objective was to determine repair durability and survival in patients with and without connective tissue disorders undergoing concomitant aortic valve reimplantation and mitral valve repair. Methods: From 2002 to 2019, 68 patients underwent concomitant aortic valve reimplantation and mitral valve repair, including 27 patients with Marfan syndrome (39.7%). Follow-up echocardiograms were analyzed using nonlinear multiphase mixed-effects cumulative logistic regression. The regurgitation grade over time was estimated by averaging patient-specific profiles. Survival and freedom from reoperation were estimated by the Kaplan-Meier method. Results: At 7 years, 11% of patients had aortic insufficiency greater than mild (severe in 2 patients). There was no difference in greater than mild aortic insufficiency between patients with or without Marfan syndrome (P = .37). Twenty percent of patients had progressed to mitral regurgitation greater than mild (severe in only 1 patient). The prevalence of recurrent mitral regurgitation was higher in those without Marfan syndrome, with greater than mild regurgitation increasing to 24% by 2 years and remaining constant thereafter (P = .04). Freedom from reoperation on the aortic valve or mitral valve was 83% at 10 years and did not differ between Marfan syndrome groups. There were no cases of perioperative mortality. Survival at 5 and 10 years was 94% and 87%, respectively, without a difference between those with and without Marfan syndrome. Conclusions: Patients can undergo a total repair strategy using combined aortic valve reimplantation and mitral valve repair procedures with a low risk of mortality and complications, with favorable freedom from both residual valve regurgitation and reoperation.
RESUMEN
OBJECTIVE: The study objective was to determine the effect of sinutubular junction stabilization on long-term outcomes of bicuspid aortic valve repair. METHODS: From January 1998 to January 2020, 419 patients underwent bicuspid aortic valve repair with ascending aorta replacement and 421 without (bicuspid aortic valve repair alone). Propensity score matching (97 pairs) was used to compare outcomes. RESULTS: Before matching, prevalence of severe aortic regurgitation at 10 years was 5.4% after bicuspid aortic valve repair + ascending aorta replacement and 10% after bicuspid aortic valve repair alone; aortic valve gradient was 20 mm Hg after bicuspid aortic valve repair + ascending aorta replacement and 19 mm Hg after bicuspid aortic valve repair alone. Ten-year freedom from reoperation overall was 79% after bicuspid aortic valve repair + ascending aorta replacement and 75% after bicuspid aortic valve repair alone; freedom from late aortic regurgitation was 93% after bicuspid aortic valve repair + ascending aorta replacement and 92% after bicuspid aortic valve repair alone; and freedom from aortic stenosis was 87% after bicuspid aortic valve repair + ascending aorta replacement and 93% after bicuspid aortic valve repair alone. Ten-year survival was 95% after bicuspid aortic valve repair + ascending aorta replacement and 96% after bicuspid aortic valve repair alone. After matching, prevalence of severe aortic regurgitation at 10 years was 11% after bicuspid aortic valve repair + ascending aorta replacement and 9.1% after bicuspid aortic valve repair alone (P = .33); aortic valve gradient was 16 mm Hg after bicuspid aortic valve repair + ascending aorta replacement and 25 mm Hg after bicuspid aortic valve repair alone (P < .0001). Ten-year freedom from reoperation was 85% after bicuspid aortic valve repair + ascending aorta replacement and 72% after bicuspid aortic valve repair alone (P = .08) overall. Ten-year freedom from reoperation for late aortic regurgitation was 88% after bicuspid aortic valve repair + ascending aorta replacement and 86% after bicuspid aortic valve repair alone (P = .65). Freedom from aortic stenosis was 97% after bicuspid aortic valve repair + ascending aorta replacement and 91% after bicuspid aortic valve repair alone (P = .03). Ten-year survival was 96% after bicuspid aortic valve repair + ascending aorta replacement and 96% after bicuspid aortic valve repair alone (P = .16). CONCLUSIONS: Bicuspid aortic valve repair with or without ascending aorta replacement is associated with good short- and long-term outcomes. Bicuspid aortic valve repair + ascending aorta replacement has a minimal effect on long-term repair durability. Sinutubular junction stabilization should not be performed for the sole purpose of long-term repair durability.

Objective: During aortic valve reimplantation, cusp repair may be needed to produce a competent valve. We investigated whether the need for aortic valve cusp repair affects aortic valve reimplantation durability. Methods: Patients with tricuspid aortic valves who underwent aortic valve reimplantation from January 2002 to January 2020 at a single center were retrospectively analyzed. Propensity matching was used to compare outcomes between patients who did and did not require aortic valve cusp repair. Results: Cusp repair was performed in 181 of 756 patients (24%). Patients who required cusp repair were more often male, were older, had more aortic valve regurgitation, and less often had connective tissue disease. Patients who underwent cusp repair had longer aortic clamp time (124 ± 43 minutes vs 107 ± 36 minutes, P = .001). In-hospital outcomes were similar between groups and with no operative deaths. A total of 98.3% of patients with cusp repair and 99.3% of patients without cusp repair had mild or less aortic regurgitation at discharge. The median follow-up was 3.9 and 3.2 years for the cusp repair and no cusp repair groups, respectively. At 10 years, estimated prevalence of moderate or more aortic regurgitation was 12% for patients with cusp repair and 7.0% for patients without cusp repair (P = .30). Mean aortic valve gradients were 6.2 mm Hg and 8.0 mm Hg, respectively (P = .01). Ten-year freedom from reoperation was 99% versus 99% (P = .64) in the matched cohort and 97% versus 97%, respectively (P = .30), in the unmatched cohort. Survival at 10 years was 98% after cusp repair and 93% without cusp repair (P = .05). Conclusions: Aortic valve reimplantation for patients with tricuspid aortic valves has excellent long-term results. Need for aortic valve cusp repair does not affect long-term outcomes and should not deter surgeons from performing valve-sparing surgery.
RESUMEN
Objectives: Debakey type I and IIIb aortic dissections are complicated by extension along the full length of the aorta. Over the long term, the thoracoabdominal aorta in these patients often continues to degenerate, requiring endovascular or open repair. The purpose of this investigation is to determine the early clinical outcome on aortic remodeling using a composite thoracic stent graft and thoracoabdominal bare metal extension stenting strategy. Methods: From April 2019 to April 2021, 73 patients with Debakey I/IIIb aortic dissection underwent endovascular stent graft repair of the descending thoracic aorta and repair of the thoracoabdominal aorta using bare metal extension stenting. Preoperative and follow-up surveillance computed tomography imaging scans were analyzed. Results: Fifty-three (73%) patients had a Debakey I aortic dissection, and 50 (69%) patients underwent surgery during the chronic (time to surgery >30 days) dissection phase. Mortality at 30 days was 4% (3 hyperacute patients). Stroke occurred in 3 (4%), paraparesis in 2 (2.7%), and acute renal failure requiring dialysis occurred in 2 (2.7%) patients. On postoperative and follow-up computed tomography, there was a significant increase in false lumen thrombosis (P < .001). This coincided with a significant increase in true lumen fraction suggestive of positive aortic remodeling (P < .001) at the time of latest follow-up. Conclusions: Altering the course of aortic remodeling, with placement of a dissection stent in the thoracoabdominal aorta simultaneous with descending thoracic aortic repair may promote true lumen re-expansion and false lumen thrombosis during acute and chronic dissection phases.
RESUMEN
OBJECTIVES: This study evaluated the feasibility and safety of same-day discharge (SDD) following transfemoral transcatheter aortic valve replacement (TF-TAVR) compared with next-day discharge (NDD). BACKGROUND: Reducing hospital length of stay is an important goal for patients and hospitals. Cleveland Clinic implemented a post-TAVR SDD pathway beginning in March 2020. METHODS: The study retrospectively analyzed patients who underwent "minimalist" outpatient TF-TAVR in 2019 to 2020. SDD was applied to patients who met the predefined criteria. Outcomes included in-hospital and 30-day events and were compared between SDD and NDD (during and prior to availability of the SDD pathway). RESULTS: In 2020, SDD and NDD accounted for 22.1% (n = 114 of 516) and 63.8% (n = 329 of 516) of outpatient TF-TAVR, respectively. SDD patients in 2020, compared with NDD patients in 2019 (n = 481), were younger, were more often male, and had a lower surgical risk. There were no significant differences in in-hospital events and 30-day readmissions (cardiovascular readmission: 3.5% vs 6.2%; P = 0.37; noncardiovascular readmission: 2.6% vs 4.0%; P = 0.78), and there were no deaths after SDD. These outcomes remained consistent after propensity score matching. Only 1 (0.9%) patient required pacemaker implantation after SDD (post-TAVR day 25). As expected based on SDD criteria, multivariable logistic regression analysis identified procedure end-time as the strongest predictor of SDD (adjusted OR: 7.74; 95% CI: 4.39-13.63), while male sex and baseline hemoglobin level were also associated with SDD. CONCLUSIONS: SDD after TF-TAVR was feasible in this early experience without impairing post-discharge safety. Our SDD pathway may serve as a useful strategy to improve bed utilization and reduce hospital stay for TAVR recipients.

Objective: Patients with thoracic aortic disease commonly present with concomitant multisegment pathology. We describe the patient population, analyze outcomes, and define the patient selection strategy for valve-preserving aortic root reimplantation (VPARR) combined with the arch procedure. Methods: From 2008 to 2018, 98 patients underwent VPARR combined with the aortic arch procedure (hemi-arch, 50% [n = 49, limited repair]; total arch, 50% [n = 49, complete repair] including 39 with elephant trunk). Indications for surgery were aneurysmal disease (61%) and aortic dissection (39%). The median follow-up was 17 months (IQR, 8 to 60 months). Results: There were no operative deaths or paraplegia, and 5 patients underwent re-exploration for bleeding. During follow-up, 2 patients required aortic valve replacement for severe aortic insufficiency at 1 and 5 years, and 4 patients died. In the limited repair group, 1 patient underwent reintervention for aortic arch replacement, whereas 4 patients underwent planned intervention (1 endovascular and 3 open thoracoabdominal aortic repair). In the complete repair group, 23 patients underwent planned intervention (15 endovascular and 8 open thoracoabdominal repair). Conclusions: Single-stage, complete, proximal aortic repair including VPARR combined with total aortic arch replacement is as safe and feasible to perform as limited arch repair and facilitates further intervention in carefully selected patients with diffuse aortic pathology at centers of expertise.
