Outcomes of Minimally Invasive Aortic Valve Replacement in Obese Patients: A Propensity-Matched Study.

INTRODUCTION: Obese patients are at risk of complications after cardiac surgery. The aim of this study is to investigate safety and efficacy of a minimally invasive approach via upper sternotomy in this setting. METHODS: We retrospectively reviewed 203 obese patients who underwent isolated, elective aortic valve replacement between January 2014 and January 2023 - 106 with minimally invasive aortic valve replacement (MIAVR) and 97 with conventional aortic valve replacement (CAVR). To account for baseline differences, a propensity-matching analysis was performed obtaining two balanced groups of 91 patients each. RESULTS: The 30-day mortality rate was comparable between groups (1.1% MIAVR vs. 0% CAVR, P=0.99). MIAVR patients had faster extubation than CAVR patients (6 ± 2 vs. 9 ± 2 hours, P<0.01). Continuous positive airway pressure therapy was less common in the MIAVR than in the CAVR group (3.3% vs. 13.2%, P=0.03). Other postoperative complications did not differ significantly. Intensive care unit stay (1.8 ± 1.2 vs. 3.2 ± 1.4 days, P<0.01), but not hospital stay (6.7 ± 2.1 vs. 7.2 ± 1.9 days, P=0.09), was shorter for MIAVR than for CAVR patients. Follow-up survival was comparable (logrank P-value = 0.58). CONCLUSION: MIAVR via upper sternotomy has been shown to be a safe and effective option for obese patients. Respiratory outcome was promising with shorter mechanical ventilation time and reduced need for post-extubation support. The length of stay in the intensive care unit was reduced. These advantages might be important for the obese patient to whom minimally invasive surgery should not be denied.

Flurbiprofen in the subglottic space to prevent postoperative sore throat after cardiac surgery: A randomized double-blind study.

STUDY OBJECTIVE: Postoperative sore throat (POST) and hoarseness are common complications of tracheal intubation. This study aims to evaluate the efficacy of flurbiprofen administered through the subglottic port of tracheal tubes to prevent POST after cardiac surgery. DESIGN: Single-center, prospective, randomized, double-blind, placebo-controlled trial. SETTING: Tertiary Care Referral University Hospital (Fondazione Policlinico Universitario A. Gemelli IRCCS, Rome). PATIENTS: Included 71 patients undergoing for elective cardiac surgery. Inclusion criteria were (a) age between 50 and 75 years, (b) NYHA class I or II, (c) surgery for myocardial revascularization or valve repair or replacement under cardiopulmonary bypass. INTERVENTION: Patients were double blind randomized to receive flurbiprofen or saline in the subglottic port of the endotracheal tube (groups F and P). The solution was injected ten minutes after tracheal tube placement, ten minutes after ICU admission and ten minutes before tracheal tube removal. MEASUREMENTS: The primary outcome was to assess the effect of topical flurbiprofen administered through the subglottic port of the tracheal tube to prevent post-operative sore throat (POST). The secondary outcomes were the presence of hoarseness safety and patient's subjective satisfaction with their recovery. We did not report any exploratory outcomes. MAIN RESULTS: We analyzed 68 patients, 34 patients in each group. In group F, two patients complained of POST and hoarseness (5.9%), while all controls did. The two groups significantly differed in the severity scores (VAS and TPS for sore throat and HOAR for hoarseness) at all time points. In group P, patients reported mild to moderate symptoms that significantly improved or disappeared 36 h after tracheal tube removal. According to the multivariable model, hoarseness affected women less than men, in the control group (p = 0.002). None of the patients in either group reported any adverse effects. CONCLUSIONS: Repeated administration of flurbiprofen through the subglottic port of tracheal tubes reduced the incidence of sore throat and hoarseness after cardiac surgery without evidence of complications.

Long-term outcome of bicuspid aortic valve disease.

AIMS: Bicuspid aortic valve (BAV) is a common congenital condition that is frequently associated with aortic stenosis (AS) and aortic regurgitation (AR), as well as aortic aneurysms, but specific outcome data are scarce. The present study sought to assess outcomes in a large cohort of consecutive patients with BAV. METHODS AND RESULTS: A total of 581 consecutive patients (median age 29 years, 157 female) with BAV were included in the study and followed prospectively in a heart valve clinic follow-up programme. The overall survival rate after 10 years was 94.5%. During follow-up, 158 patients developed an indication for surgery. Event-free survival rates were 97%, 94%, 87%, and 73% at 1, 2, 5, and 10 years, respectively. In the multivariable analysis, event rates were independently predicted by AS [subdistribution hazard ratio (SHR) 2.3 per degree of severity], AR (SHR 1.5 per degree of severity), baseline aortic dilatation ≥ 40 mm (SHR 1.9), and age (SHR 1.3) (P < 0.001). CONCLUSION: BAV disease is associated with a high rate of cardiac events, but state-of-the-art care results in good survival with low rates of infective endocarditis, aortic dissection, and sudden death. Incremental degrees of AS and regurgitation, the presence of aortic dilatation, and age are predictive of cardiac events.

Temporal trends of frame expansion and paravalvular leak reduction after transcatheter aortic valve replacement with self-expandable prostheses.

BACKGROUND: Paravalvular leakage (PVL) is a common finding after transcatheter aortic valve replacement (TAVR) and affects late clinical outcome. It is more frequent with self-expandable (SE) transcatheter-heart-valve (THV). Few is known about SE-THV expansion after implantation. The purpose is to assess SE-THV frame expansion and its possible influence on PVL. METHODS: We designed a prospective pilot study to assess the time-course of SE-THV frame dimensions and PVL after TAVR. Consecutive patients undergoing TAVR with SE-THV were enrolled. Prosthesis fluoroscopy and echocardiography were prospectively performed immediately after TAVR (T0) and before discharge (T1) to grade PVL. Prosthesis diameters were assessed in 2 fluoroscopic orthogonal views. PVL reduction ≥1+ from T0 to T1 at echocardiography was the primary study endpoint. RESULTS: Twenty-five patients were enrolled. Mean interval between T0 and T1 evaluations was 5 days. Grade 1 or 2 was present in 76% of patients at T0 and in 68% at T1 (P=0.034). A total of 7 patients (28%) improved PVL ≥1 grade from T0 to T1. Differences between T0 and T1 fluoroscopic diameters were not statistically significant. When comparing the diameter changes according to PVL evolution, patients with PVL improvement (as compared with those without) had significantly larger minimum diameter increase at both annulus/inflow (P=0.016) and outflow/distal edge (P=0.027). CONCLUSIONS: PVL may improve in the early days after SE-THV and those patients with PVL improvement may have THV frame expansion. Further studies are needed to confirm such preliminary observations and to establish the clinical relevance of this phenomenon.

The multidisciplinary Heart Team approach for patients with cardiovascular disease: a step towards personalized medicine.

AIMS: Despite general agreement on the benefits of the Heart Team approach for patients with cardiac diseases, few data are available on its real impact on the decision-making process. The aim of the study is to define the evolution over time of the level of agreement with the systematic discussion of patients in the Heart Team and to evaluate the adherence to the Heart Team recommendations and the impact of the Heart Team on the clinical outcome of the patients. METHODS: In 2015--2016, an experienced cardiac surgeon and a cardiologist independently reviewed clinical data of a series of 100 patients (Group 1, G1) and subsequently for each patient recommended treatment (surgical, percutaneous, hybrid or medical therapy) or further diagnostic investigations. The next day, each case was discussed by the Hospital Heart Team. The Heart Team recommendation, the subsequent treatment received by the patient and the in-hospital outcome were recorded. The same study procedure was repeated in 2017 in a second (G2) and in 2018 in a third (G3) group, both of them including 100 patients. RESULTS: Complete agreement in treatment selection by the cardiac surgeon, cardiologist and the Heart Team was observed in 43% of cases in G1 and in 70% and 68% in G2 and G3, respectively (G1 vs. G2: P  < 0.001, G1 vs. G3: P  = 0.01, G2 vs. G3: P  = 0.30). Agreement was less frequent in patients with a higher risk profile and in patients with aortic valve stenosis. The Heart Team decision was implemented in 95% of cases with a 30-day mortality of 0.67%. CONCLUSION: Agreement in treatment selection among the cardiac surgeon, cardiologist and Heart Team appears to be low in the initial experience. Subsequently, it seems to steadily increase over time up to a limit, when it reaches a plateau of stable results. Heart Team clinical cases discussion, based on both guidelines and multidisciplinary experience, represents a key step in defining the best patient treatment pathway, potentially improving the decision-making process and clinical results.

Comparison of De-Kay repair versus De Vega suture for functional tricuspid regurgitation: a preliminary experience.

BACKGROUND: In patients undergoing mitral valve surgery, restrictive suture annuloplasty (De Vega) for less-than-severe functional tricuspid regurgitation has been proven to be safe and effective. The aim of this study is to determine whether the adjunct of the plication of the posterior tricuspid leaflet with the same running suture (bicuspidized De Vega or "De Kay") is equally safe and effective. METHODS: Single center, retrospective study on patients submitted to suture repair of the tricuspid valve during mitral valve surgery, with either conventional or De Kay, between January 2014 and December 2020. Comparison was based on degree of residual tricuspid valve regurgitation and right ventricular assessment at discharge. RESULTS: Over the course of the study period, 255 patients undergoing mitral valve surgery had a dilated (>40 mm or >20 mm/m2) tricuspid valve annulus, with less-than-severe tricuspid regurgitation. Conventional De Vega was employed in 166 patients (65.1%) and De Kay in the remaining 89 (34.9%). At discharge the adjunct of postero-septal commissure plication has similar outcomes to the classic De Vega repair. It seems to preserve right ventricular function. CONCLUSIONS: De Kay repair guarantees the same tricuspidal regurgitation reduction as compared with conventional De Vega early after surgery.

Two innovative aortic bioprostheses evaluated in the real-world setting. First results from a two-center study.

BACKGROUND: The increasing use of biological substitutes for surgical aortic valve replacement (AVR), has led to the development of new bioprostheses with improved hemodynamics and expected durability. METHODS: In this observational retrospective two-center cohort study, two innovative bioprostheses, INSPIRIS Resilia and AVALUS were analyzed. We analyzed early and 2.4-year follow-up results in terms of safety, clinical outcome and hemodynamic performance. RESULTS: From November 2017 to February 2021, 148 patients underwent AVR with INSPIRIS Resilia (N.=74) or AVALUS (N.=74) bioprosthesis. The 30-day and mid-term mortality was comparable (1% vs. 3%, P=0.1 and 7% vs. 4%, P=0.4, respectively). Valve-related mortality was observed in one AVALUS patient. Three (4%) patients of the AVALUS group developed prosthetic endocarditis and two of them died after reoperation. No other cases of prosthetic endocarditis were observed. No cases of structural valve degeneration or significant paravalvular leak were detected at follow-up. Median follow-up peak pressure gradient was 21 vs. 23 mmHg (P=0.4) and the mean pressure gradient was 12 vs. 13 mmHg (P=0.9) for Inspiris and AVALUS, respectively. The effective orifice area (EOA) and indexed EOA were 1.5 cm2 vs. 1.4 cm2 (P=0.4) and 0.8 vs. 0.7 cm2/m2 (P=0.5), respectively. Indexed left ventricular mass regression was -33 vs. -52 g/m2 for the Inspiris and AVALUS groups, respectively, (R2-adjusted =0.14; P<0.01). CONCLUSIONS: INSPIRIS Resilia and AVALUS bioprostheses were reliable with comparable results in safety, clinical outcome and hemodynamic performance. After statistical adjustment, AVALUS was associated with better left ventricular mass reduction. Long-term follow-up would provide definitive comparative results.

Impacto clínico de la extensión del miocardio en riesgo en pacientes sometidos a intervención percutánea de la válvula aórtica / Clinical impact of the extent of jeopardized myocardium in patients undergoing transcatheter aortic valve intervention

Introducción y objetivos La enfermedad coronaria (EC) se encuentra en el 30-50% de los pacientes con estenosis aórtica (EA) grave que reciben tratamiento intervencionista. Todavía no está claro cuál es el mejor tratamiento de la EAC en pacientes con EA sometidos a implante percutáneo de válvula aórtica (TAVI). El objetivo del estudio fue analizar el impacto clínico del miocardio en riesgo en pacientes con EAC y EA grave tratados con TAVI. Métodos Se incluyó a pacientes consecutivos sometidos a TAVI en nuestro hospital. En presencia de EAC, el miocardio en riesgo antes del procedimiento se clasificó utilizando la puntuación de riesgo (JS) de la British Cardiovascular Intervention Society (BCIS). La población de estudio se dividió en 3 grupos: pacientes sin EAC concomitante (grupo No-EAC), pacientes con EAC y BCIS-JS ≤ 4 (grupo EAC BCIS-JS ≤ 4) y pacientes con EAC concomitante y BCIS-JS> 4 (grupo EAD BCIS -JS> 4). El objetivo primario del estudio fueron los eventos cardiovasculares y cerebrovasculares adversos mayores (MACCE). Resultados Se incluyó a un total de 403 pacientes: 223 No-EAD, 94 EAC BCIS-JS ≤ 4 y 86 EAC BCIS-JS> 4. Con 3 meses de seguimiento [rango 104 – 3.296 días], los pacientes sin EAC y los pacientes con EAC con BCIS-JS ≤ 4 tuvieron una mejor supervivencia libre de MACCE en comparación con aquellos con revascularización menos extensa (BCIS-JS> 4) (p=0,049). Este resultado se debió en parte a una reducción significativa de la mortalidad (p=0,031). En el análisis multivariado, el BCIS-JS residual ≤ 4 y la clase III-IV de la NYHA predijeron MACCE de forma independiente. Conclusiones En pacientes con EAC y EA grave, la extensión del miocardio en riesgo antes del TAVI influye en los resultados clínicos (AU)

Introduction and objectives Coronary artery disease (CAD) is found in 30%-50% of patients with severe aortic stenosis (AS) undergoing treatment. The best management of CAD in AS patients undergoing transcatheter aortic valve implantation (TAVI) is still unclear. We investigated the clinical impact of the extent of jeopardized myocardium in patients with concomitant CAD and severe AS treated by TAVI. Methods Consecutive patients who underwent TAVI procedures at our hospital were identified. In the presence of CAD, the myocardium jeopardized before TAVI was graded using the British Cardiovascular Intervention Society (BCIS) jeopardy score (JS). The study population was divided in 3 groups: patients without concomitant CAD (no-CAD), patients with CAD and BCIS-JS ≤ 4 (CAD BCIS-JS ≤ 4) and patients with concomitant CAD and BCIS-JS> 4 (CAD BCIS-JS> 4). The primary study endpoint was major adverse cardiovascular and cerebrovascular events (MACCE). Results A total of 403 patients entered the study: 223 no-CAD, 94 CAD BCIS-JS ≤ 4 and 86 CAD BCIS-JS> 4. At> 3 months of follow-up [range 104–3296 days], patients without CAD and CAD patients with BCIS-JS ≤ 4 had better survival free from MACCE compared with those with less extensive revascularization (BCIS-JS> 4) (P=.049). This result was driven by a significant reduction in death (P=.031). On multivariate analysis, residual BCIS-JS ≤ 4 and NYHA class III-IV independently predicted MACCE. Conclusions In patients with concomitant CAD and severe AS, the extent of jeopardized myocardium before TAVI impacts on clinical outcomes (AU)

Extensive corpus callosum ischemia after coronary artery bypass grafting on extracorporeal circulation.

INTRODUCTION: Heart surgery can be associated with adverse ischemic brain events. CASE REPORT: Here, we describe two patients who presented extensive infarction of the corpus callosum and of other brain watershed areas following coronary artery bypass grafting (CABG) on extracorporeal circulation (ECC). DISCUSSION: Infarction of the corpus callosum is an extremely rare condition due to its abundant blood supply. Our findings are noteworthy since they diverge from classical brain watershed infarcts and from other cases of corpus callosum involvement. This suggests that in some cases, CABG surgery on ECC may be associated to a profound impairment of intracerebral circulation. However, it is also possible that the corpus callosum is particularly vulnerable to yet unknown metabolic modifications connected to ECC. CONCLUSIONS: Further studies are needed in order to investigate the complex response of brain circulation and metabolism during heart surgery with ECC.

Performance, clinical outcomes and implementation of an original heart valve clinic model.

BACKGROUND: Valvular heart disease (VHD) requires optimized outpatient management that is generally considered to be best delivered by a dedicated, multidisciplinary team (Heart Valve Clinic [HVC]). Although HVC is promoted by clinical guidelines and organized in many centers, real world outcome assessments are limited. Thus, we evaluated the performance, clinical and management outcomes during a 6-year experience with an original HVC model. METHODS: By interrogating the local database, 1047 consecutive patients admitted to the HVC from January 2015 to October 2020 were found. Management and mortality were checked for all patients. After 3 years of HVC activity, in order to improve appropriateness and efficiency, access priority criteria were introduced. Thus, the study population was divided in two period subgroups (before and after access criteria introduction) that were compared. RESULTS: A total of 1047 consecutive patients admitted to the HVC constituted the study population; 346 patients (33%) were recommended for invasive treatment. After a mean follow-up of 25.7±3.1 months, 37 patients (3.5%) died. When comparing study periods, statistically significant increase inpatients' complexity and VHD severity was noticed in Period 2, also translating into higher rate of referral to intervention (39.0% vs. 29.4% in Period 1; P=0.001). Finally, despite higher rate of elderly and frail patients, operative mortality was not jeopardized. CONCLUSIONS: The present study reports a comprehensive assessment of the characteristics and outcomes achieved through an original HVC model. Standardization of access criteria supports the HVC improvement.

Restricted T-Cell Repertoire in the Epicardial Adipose Tissue of Non-ST Segment Elevation Myocardial Infarction Patients.

Aims: Human epicardial adipose tissue, a dynamic source of multiple bioactive factors, holds a close functional and anatomic relationship with the epicardial coronary arteries and communicates with the coronary artery wall through paracrine and vasocrine secretions. We explored the hypothesis that T-cell recruitment into epicardial adipose tissue (EAT) in patients with non-ST segment elevation myocardial infarction (NSTEMI) could be part of a specific antigen-driven response implicated in acute coronary syndrome onset and progression. Methods and Results: We enrolled 32 NSTEMI patients and 34 chronic coronary syndrome (CCS) patients undergoing coronary artery bypass grafting (CABG) and 12 mitral valve disease (MVD) patients undergoing surgery. We performed EAT proteome profiling on pooled specimens from three NSTEMI and three CCS patients. We performed T-cell receptor (TCR) spectratyping and CDR3 sequencing in EAT and peripheral blood mononuclear cells of 29 NSTEMI, 31 CCS, and 12 MVD patients. We then used computational modeling studies to predict interactions of the TCR beta chain variable region (TRBV) and explore sequence alignments. The EAT proteome profiling displayed a higher content of pro-inflammatory molecules (CD31, CHI3L1, CRP, EMPRINN, ENG, IL-17, IL-33, MMP-9, MPO, NGAL, RBP-4, RETN, VDB) in NSTEMI as compared to CCS (P < 0.0001). CDR3-beta spectratyping showed a TRBV21 enrichment in EAT of NSTEMI (12/29 patients; 41%) as compared with CCS (1/31 patients; 3%) and MVD (none) (ANOVA for trend P < 0.001). Of note, 11/12 (92%) NSTEMI patients with TRBV21 perturbation were at their first manifestation of ACS. Four patients with the first event shared a distinctive TRBV21-CDR3 sequence of 178 bp length and 2/4 were carriers of the human leukocyte antigen (HLA)-A*03:01 allele. A 3D analysis predicted the most likely epitope able to bind HLA-A3*01 and interact with the TRBV21-CDR3 sequence of 178 bp length, while the alignment results were consistent with microbial DNA sequences. Conclusions: Our study revealed a unique immune signature of the epicardial adipose tissue, which led to a 3D modeling of the TCRBV/peptide/HLA-A3 complex, in acute coronary syndrome patients at their first event, paving the way for epitope-driven therapeutic strategies.

Pledget-assisted hemostasis to fix residual access-site bleedings after double pre-closure technique.

BACKGROUND: The use of pre-closure suture-based devices represents a widely access-site hemostasis technique in percutaneous transfemoral transcatheter-aortic-valve-replacement (TF-TAVR); yet this technique is associated with the risk of a device failure that may result in clinically relevant residual bleeding. Thus, a bailout intervention is needed. So far, the best management of pre-closure device failure has not been recognized. AIM: To report the first clinical results obtained using a novel bailout hemostasis technique for patients with double suture-based vascular closure device failure in the setting of TF-TAVR. METHODS: We developed a "pledget-assisted hemostasis" technique to manage residual access-site bleeding. This consists of the insertion of a surgical, non-absorbable, polytetrafluoroethylene pledget over the sutures of the two ProGlide (Abbott Vascular, CA, United States). The ProGlide's knot-pushers are used to push down the pledget and the hand-made slipknot to seal the femoral artery leak. This technique was used as a bailout strategy in patients undergoing TF-TAVR with a systematic double pre-closure technique. Post-procedural access-site angiography was systematically performed. In-hospital complications were systematically detected and classified according to Valve Academic Research Consortium-2 criteria. RESULTS: Out of 136 consecutive patients who underwent TF-TAVR, 15 patients (mean age 80.0 ± 7.2 years, 66.7% female) with access-site bleeding after double pre-closure technique failure were treated by pledget-assisted hemostasis. In the majority of patients, 16F sheath was used (n = 12; 80%). In 2 cases (13%), a peripheral balloon was also inflated in the iliac artery to limit blood loss during pledget preparation. Angiography-confirmed hemostasis (primary efficacy endpoint) was achieved in all patients. After the procedure, 1 patient required blood transfusion (2 units), and no other bleeding or major ischemic complication was noticed. CONCLUSION: The "pledget assisted hemostasis" might be considered as a possible bailout technique to treat patients with residual access site bleeding. Further studies are needed to compare this approach with other bail-out techniques.

Transcatether Aortic Valve Implantation to Treat Degenerated Surgical Bioprosthesis: Focus on the Specific Procedural Challenges.

Actually transcatheter aortic valve implantation within failed surgically bioprosthetic valves (VIV-TAVI) is an established procedure in patients at high risk for repeat surgical aortic valve intervention. Although less invasive than surgical reintervention, VIV-TAVI procedure offers potential challenges, such as higher rates of prosthesis-patient mismatch and coronary obstruction. Thus, optimal procedural planning plays an important role to minimize the risk of procedure complications. In this review, we describe the key points of a VIV-TAVI procedure to optimize outcomes and reduce the risk of procedure complications.

Clinical Impact of Heart Team Decisions for Patients With Complex Valvular Heart Disease: A Large, Single-Center Experience.

Background A multidisciplinary approach might be pivotal for the management of patients with valvular heart disease (VHD), but clinical outcome data are lacking. Methods and Results At our institution, since 2014, internal guidelines recommended heart team consultations for patients with VHD. The clinical/echocardiographic characteristics, treatment recommendations, performed treatment, and early clinical outcomes of consecutive, hospitalized patients with VHD undergoing heart team evaluation were collected. Surgical risk was prospectively assessed by the EuroSCORE II and STS-PROM. The primary end point of the study was early mortality. A total of 1004 patients with VHD with high clinical complexity (mean age, 75 years; mean EuroSCORE II, 9.4%; mean STS-PROM, 5.6%; 48% ischemic heart disease; 29% chronic kidney disease, 9% oncologic/hematologic diseases) were enrolled. The heart team recommended an interventional treatment for 807 (80%) patients and conservative management for 197 (20%) patients. Management crossovers occurred in only 5% of patients. The recommended intervention was cardiac surgery for 230 (23%) patients, percutaneous treatment in 516 (51%) patients, and hybrid treatment in 61 (6%) patients. Early mortality occurred in 24 patients (2.4%) and was independently predicted by aortic stenosis, left ventricular ejection fraction, pulmonary artery systolic pressure, and conservative management recommendation. In patients referred to treatment, observed early mortality (1.7%) was significantly lower (P<0.001) than expected on the bases of both the STS-PROM (5.2%) and EuroSCORE II (9.7%). Conclusions Within the limitations of its single-center and observational design, the present study suggests that heart team-based management of patients with complex VHD is feasible and allows referral to a wide spectrum of interventions with promising early clinical results.
