ABSTRACT

BACKGROUND AND AIMS: There is significant potential to streamline the clinical pathway for patients undergoing transcatheter aortic valve implantation (TAVI). The purpose of this study was to evaluate the effect of implementing BENCHMARK best practices on the efficiency and safety of TAVI in 28 sites in 7 European countries. METHODS: This was a study of patients with severe symptomatic aortic stenosis (AS) undergoing TAVI with balloon-expandable valves before and after implementation of BENCHMARK best practices. Principal objectives were to reduce hospital length of stay (LoS) and duration of intensive care stay. Secondary objective was to document patient safety. RESULTS: Between January 2020 and March 2023, 897 patients were documented prior to and 1491 patients after the implementation of BENCHMARK practices. Patient characteristics were consistent with a known older TAVI population and only minor differences. Mean LoS was reduced from 7.7 ± 7.0 to 5.8 ± 5.6 days (median 6 vs. 4 days; P < .001). Duration of intensive care was reduced from 1.8 to 1.3 days (median 1.1 vs. 0.9 days; P < .001). Adoption of peri-procedure best practices led to increased use of local anaesthesia (96.1% vs. 84.3%; P < .001) and decreased procedure (median 47 vs. 60 min; P < .001) and intervention times (85 vs. 95 min; P < .001). Thirty-day patient safety did not appear to be compromised with no differences in all-cause mortality (0.6% in both groups combined), stroke/transient ischaemic attack (1.4%), life-threatening bleeding (1.3%), stage 2/3 acute kidney injury (0.7%), and valve-related readmission (1.2%). CONCLUSIONS: Broad implementation of BENCHMARK practices contributes to improving efficiency of TAVI pathway reducing LoS and costs without compromising patient safety.

ABSTRACT

BACKGROUND: Transcatheter aortic valve implantation (TAVI) is increasingly being used in younger patients and those with lower peri-procedural risk, meaning more patients will live long enough to experience structural valve deterioration (SVD) of the bioprosthesis, indicating repeated TAVI. Experience of repeated TAVI-transcatheter heart valve (THV) implantation into an index THV is limited. This registry aims to assess the peri-procedural and short-term safety, efficacy and durability of repeated TAVI. METHODS: The ReTAVI Prospective observational registry is an investigator-initiated, multicentre, international, prospective registry of patients undergoing repeated TAVI using balloon-expandable SAPIEN prosthesis to evaluate procedural and short-term safety, efficacy and durability as well as anatomical and procedural factors associated with optimal results. The registry will enrol at least 150 patients across 60 high-volume centres. Patients must be ≥18 years old, have had procedural success with their first TAVI, have index THV device failure, intend to undergo repeated TAVI and be considered suitable candidates by their local Heart Team. All patients will undergo a 30-day and 12-month follow-up. The estimated study completion is 2025. CONCLUSIONS: The registry will collect pre-, peri-, postoperative and 12-months data on patients undergoing repeated TAVI procedures with THVs for failure of the index THV and determine VARC-3-defined efficacy and safety at 30 days and functional outcome at 12 months. The registry will expand existing data sets and identify patient characteristics/indicators related to complications and clinical benefits for patients with symptomatic severe calcific degenerative aortic stenosis.

ABSTRACT

BACKGROUND: Transcatheter aortic valve implantation (TAVI) has become the standard treatment for severe aortic valve stenosis in patients at increased surgical risk. Percutaneous transfemoral (TF) is the access of choice due to its reduced invasiveness and perioperative morbidity/mortality compared with the trans-axillary, aortic, and apical routes. On the other hand, vascular access complications (VACs) of the TF access are associated with prolonged hospitalization, 30-day, and 1-year mortality. In addition, the concomitance of peripheral arterial disease may require associated endovascular management. A multidisciplinary team with Interventional Cardiologists and Vascular Surgeons may minimize the rate of VACs in patients with challenging femoral-iliac access or concomitant disease of other vascular districts, thus optimizing the outcome of TF-TAVI. The aim of this study was to evaluate the role of Vascular Surgeons in TF TAVI procedures. METHODS: We conducted a retrospective single-center review of all TF-TAVI procedures assisted by Vascular Surgeons between January 2016 and December 2020 in a high-volume tertiary hospital. Pre, intra, and postoperative data were analyzed by a dedicated group of Interventional Cardiologists and Vascular Surgeons. VACs were defined according with the Valve Academic Research Consortium (VARC) three guidelines. The outcomes of TF-TAVI procedures with Vascular Surgeons involvement were assessed as study's endpoints. RESULTS: Overall, 937 TAVI procedures were performed with a TF approach ranging between 78% (2016) and 98% (2020). Vascular Surgeons were involved in 67 (7%) procedures with the following indications: concomitant abdominal aortic aneurysm (EVAR + TAVI) - 3 (4%), carotid stenosis (TAVI + CAS) - 2 (3%), hostile femoral/iliac access, or VACs - 62 (93%). Balloon angioplasty of iliac artery pre-TAVI implantation was performed in 51 cases (conventional PTA: 38/51%-75%; conventional PTA + intravascular lithotripsy: 13/51%-25%; stenting: 5/51%-10%). TAVI procedure was successfully completed by percutaneous TF approach in all 62 cases with challenging femoral/iliac access. VACs necessitating interventions were 18/937 (2%) cases, localized to the common femoral or common/external iliac artery in 15/18 (83%) and 3/18 (17%) cases, respectively. They were managed by surgical or endovascular maneuvers in 3/18 (17%) and 15/18 (83%) cases, respectively. Fifteen/18 (83%) VACs were treated during the index procedure. There was no procedure-related mortality or 30-day readmission. CONCLUSION: In our experience, Vascular Surgeon assistance in TAVI procedures was not infrequent and allowed safe and effective device introduction through challenging TF access. Similarly, the concomitant significant disease of other vascular districts could be safely addressed, potentially reducing postoperative related mortality and morbidity. The implementation of multidisciplinary team with interventional cardiologists and vascular surgeons should be encouraged whenever possible.

ABSTRACT

BACKGROUND: Surgical aortic valve bioprostheses may degenerate over time and require redo intervention. Transcatheter aortic valve replacement (TAVR) is a less invasive alternative to redo surgery. The BAlloon Expandable vs. SElf Expanding Transcatheter VaLve for Degenerated BioprosthesIs (BASELINE) trial was designed to compare the performance of the balloon-expandable SAPIEN-3 Ultra and the self-expanding EVOLUT PRO+ valve systems in symptomatic patients with a failing surgical bioprosthesis. METHODS: The BASELINE trial is an investigator-initiated, non-funded, prospective, randomized, open-label, superiority trial enrolling a total of 440 patients in up to 50 sites in 12 countries in Europe and North-America. The primary endpoint is device success at 30-days defined by the Valve Academic Research Consortium-3 Criteria as the composite of technical success, freedom from mortality, freedom for surgery or intervention related to the device or to a major vascular or access-related or cardiac structural complication with an intended performance of the valve (mean gradient <20 mmHg and less than moderate aortic regurgitation). The co-primary endpoint at 1 year is defined as the composite of all-cause death, disabling stroke, rehospitalization for heart failure or valve related problems. Independent Core Laboratories will conduct uniform analyses of echocardiography (pre-, post-, 1-year post-procedure), multi-sliced computed tomography (pre-, and if available post-procedure) and cine-fluoroscopy studies. CONCLUSIONS: The BASELINE trial is a head-to-head comparative trial investigating the 2 most used contemporary transcatheter heart valves for the treatment of a failing surgical aortic bioprosthesis. (ClinicalTrials.gov number NCT04843072).

ABSTRACT

Acute coronary occlusion during transcatheter aortic valve implantation (TAVI) is a rare but potentially lethal complication. Main mechanisms are sinus insufficiency or sinus sequestration with well-described risk factors. We present two cases of acute right coronary artery occlusion during TAVI with a self-expanding valve in the absence of classical risk factors and propose a novel mechanism.

ABSTRACT

BACKGROUND: Drug-coated balloons (DCBs) have shown comparable results with drug-eluting stents in small vessel disease (SVD) percutaneous coronary intervention (PCI) in terms of target vessel revascularization and a reduced incidence of myocardial infarction. However, the relatively high rate of bail-out stenting (BOS) still represents a major drawback of DCB PCI. AIMS: The aim of the study was to investigate the clinical, anatomic, and procedural features predictive of BOS after DCB PCI in SVD. METHODS: We included all consecutive patients undergoing PCI at our institution between January 2020 and May 2022 who were treated with DCB PCI of a de novo lesion in a coronary vessel with a reference vessel diameter (RVD) between 2.0 and 2.5 mm. Angiographic success was defined as a residual stenosis <30% without flow-limiting dissection. Patients who did not meet these criteria underwent BOS. RESULTS: A total of 168 consecutive patients and 216 coronary stenoses were included. The rate of bail-out stent was 13.9%. On multivariate analysis, DCB/RVD ratio (odds ratio [OR]: 4.39, 95% confidence interval [CI]: 1.71-11.29, p < 0.01), vessel tortuosity (OR: 7.00, 95% CI: 1.66-29.62, p < 0.01), distal vessel disease (OR: 5.66, 95% CI: 2.02-15.83, p < 0.01), and high complexity (Grade C of ACC/AHA classification) coronary stenoses (OR: 6.31, 95% CI: 1.53-26.04, p = 0.01) were independent predictors of BOS. CONCLUSIONS: BOS is not an infrequent occurrence in DCB PCI of small vessels and is correlated with vessel tortuosity, distal diffuse vessel disease, higher lesion complexity, and balloon diameter oversizing.

ABSTRACT

BACKGROUND: Evidence of clinical impact of PPM after TAVI is conflicting and might vary according to the type of valve implanted. AIMS: To assess the clinical impact of prosthesis-patient mismatch (PPM) after transcatheter aortic valve implantation (TAVI) with balloon-expandable (BEV) and self-expandable valves (SEV) in patients with small annuli. METHODS: TAVI-SMALL 2 enrolled 628 patients in an international retrospective registry, which included patients with severe aortic stenosis and small annuli (annular perimeter <72 mm or area <400 mm2 ) treated with transfemoral TAVI at 16 high-volume centers between 2011 and 2020. Analyses were performed comparing patients with less than moderate (n = 452), moderate (n = 138), and severe PPM (n = 38). Primary endpoint was incidence of all-cause mortality. Predictors of all-cause mortality and PPM were investigated. RESULTS: At a median follow-up of 380 days (interquartile range: 210-709 days), patients with severe PPM, but not moderate PPM, had an increased risk of all-cause mortality when compared with less than moderate PPM (log-rank p = 0.046). Severe PPM predicted all-cause mortality in patients with BEV (hazard ratio [HR]: 5.20, 95% confidence interval [CI]: 1.27-21.2) and intra-annular valves (IAVs, HR: 4.23, 95% CI: 1.28-14.02), and it did so with borderline significance in the overall population (HR: 2.89, 95% CI: 0.95-8.79). Supra-annular valve (SAV) implantation was the only predictor of severe PPM (odds ratio: 0.33, 95% CI: 0.13-0.83). CONCLUSIONS: Patients with small aortic annuli and severe PPM after TAVI have an increased risk of all-cause mortality at early term follow-up, especially after IAV or BEV implantation. TAVI with SAV protected from severe PPM.

ABSTRACT

BACKGROUND: Cardiogenic shock (CS) includes several phenotypes with heterogenous hemodynamic features. Timely prognostication is warranted to identify patients requiring treatment escalation. We explored the association of the updated Society for Cardiovascular Angiography and Interventions (SCAI) stages classification with in-hospital mortality using a prospective national registry. METHODS: Between March 2020 and February 2022 the Altshock-2 Registry has included 237 patients with CS of all etiologies at 11 Italian Centers. Patients were classified according to their admission SCAI stage (assigned prospectively and independently updated according to the recently released version). In-hospital mortality was evaluated for association with both admission and 24-h SCAI stages. RESULTS: The overall in-hospital mortality was 38%. Of the 237 patients included and staged according to the updated SCAI classification, 20 (8%) had SCAI shock stage B, 131 (55%) SCAI stage C, 61 (26%) SCAI stage D and 25 (11%) SCAI stage E. In-hospital mortality stratified according to the SCAI classification at 24 h was 18% for patients in SCAI stage B, 27% for SCAI stage C, 63% for SCAI stage D and 100% for SCAI stage E. Both the revised SCAI stages on admission and at 24 h were associated with in-hospital mortality, but the classification potential slightly increased at 24-h. After adjusting for age, sex, lactate level, eGFR, CVP, inotropic score and mechanical circulatory support [MCS], SCAI classification at 24 h was an independent predictor of in-hospital mortality. CONCLUSIONS: In the Altshock-2 registry the utility of SCAI shock stages to identify risk of in-hospital mortality increased at 24 h after admission. Escalation of treatment (either pharmacological or with MCS) should be tailored to achieve prompt clinical improvement within the first 24 h after admission. Registration: http://www.

ABSTRACT

BACKGROUND: Mitral valve-in-valve (ViV) and valve-in-ring (ViR) are alternatives to surgical reoperation in patients with recurrent mitral valve failure after previous surgical valve repair or replacement. Our aim was to perform a large-scale analysis examining midterm outcomes after mitral ViV and ViR. METHODS: Patients undergoing mitral ViV and ViR were enrolled in the Valve-in-Valve International Data Registry. Cases were performed between March 2006 and March 2020. Clinical endpoints are reported according to the Mitral Valve Academic Research Consortium (MVARC) definitions. Significant residual mitral stenosis (MS) was defined as mean gradient ≥10 mm Hg and significant residual mitral regurgitation (MR) as ≥ moderate. RESULTS: A total of 1079 patients (857 ViV, 222 ViR; mean age 73.5±12.5 years; 40.8% male) from 90 centers were included. Median STS-PROM score 8.6%; median clinical follow-up 492 days (interquartile range, 76-996); median echocardiographic follow-up for patients that survived 1 year was 772.5 days (interquartile range, 510-1211.75). Four-year Kaplan-Meier survival rate was 62.5% in ViV versus 49.5% for ViR (P<0.001). Mean gradient across the mitral valve postprocedure was 5.7±2.8 mm Hg (≥5 mm Hg; 61.4% of patients). Significant residual MS occurred in 8.2% of the ViV and 12.0% of the ViR patients (P=0.09). Significant residual MR was more common in ViR patients (16.6% versus 3.1%; P<0.001) and was associated with lower survival at 4 years (35.1% versus 61.6%; P=0.02). The rates of Mitral Valve Academic Research Consortium-defined device success were low for both procedures (39.4% total; 32.0% ViR versus 41.3% ViV; P=0.01), mostly related to having postprocedural mean gradient ≥5 mm Hg. Correlates for residual MS were smaller true internal diameter, younger age, and larger body mass index. The only correlate for residual MR was ViR. Significant residual MS (subhazard ratio, 4.67; 95% CI, 1.74-12.56; P=0.002) and significant residual MR (subhazard ratio, 7.88; 95% CI, 2.88-21.53; P<0.001) were both independently associated with repeat mitral valve replacement. CONCLUSIONS: Significant residual MS and/or MR were not infrequent after mitral ViV and ViR procedures and were both associated with a need for repeat valve replacement. Strategies to improve postprocedural hemodynamics in mitral ViV and ViR should be further explored.

ABSTRACT

The intra-aortic balloon pump (IABP) is widely implanted as temporary mechanical circulatory support for cardiogenic shock (CS). However, its use is declining following the results of the IABP-SHOCK II trial, which failed to show a clinical benefit of the IABP in acute coronary syndrome (ACS)-related CS. Acute-on-chronic heart failure has become an increasingly recognized, distinct cause of CS (HF-CS). The pathophysiology of HF-CS differs from that of ACS-CS because it typically represents the progression from a state of congestion (with relatively preserved cardiac output) to a low-output state with hypoperfusion. The IABP is a volume-displacement pump that promotes forward flow from a high-capacitance reservoir to low-capacitance vessels, improving peripheral perfusion and decreasing left ventricular afterload in the setting of high filling pressures. The IABP can improve ventricular-vascular coupling and, therefore, myocardial energetics. Additionally, many patients with HF-CS are candidates for cardiac replacement therapies (left ventricular assist device or heart transplantation) and, therefore, may benefit from a bridge strategy that stabilizes the hemodynamics and end-organ function in preparation for more durable therapies. Notably, the new United Network for Organ Sharing donor heart allocation system has recently prioritized patients on IABP support. This review describes the role of IABP in the treatment of HF-CS. It also briefly discusses new strategies for vascular access as well as fully implantable versions for longer duration of support.

ABSTRACT

Challenging femoral/iliac access (CA) can lead to vascular complications which can hamper the clinical benefit of transfemoral (TF) transcatheter aortic valve implantation (TAVI). In this sense, iliac artery rupture is a severe complication associated with significant morbidity and mortality. We report a case of TF-TAVI managed with the "paving and cracking technique" to overcome CA.

ABSTRACT

Transcatheter aortic valve implantation (TAVI) in noncalcified pure aortic valve regurgitation is challenging as dedicated valves are not widely available. We present a case series of four inoperable patients who underwent compassionate TAVI for this indication at our institution with a balloon-expandable valve. In this context, we analyzed the relevant technical aspects such as the need for larger oversizing of the transcatheter prosthesis and the safety and limits of valve overexpansion.

ABSTRACT

BACKGROUND: Uncovered struts are a determinant of stent failure. The impact of plaque composition and procedural factors on the occurrence, evolution, and outcomes of uncovered struts in a high-risk setting has not been investigated. OBJECTIVE: To investigate the determinants and long-term clinical impact of largely uncovered struts (LUS) in thin-struts drug-eluting stents (DES) implanted in complex lesions by intracoronary optical coherence tomography (OCT). METHODS: Ninety patients with multivessel disease undergoing staged complete revascularization were randomly assigned to bioabsorbable or durable polymer DES. OCT were serially performed during the index procedure, at 3- and 18-month follow-up, and analyzed by an independent core lab. Struts were defined uncovered by OCT if no tissue was visible above the struts. LUS were defined as ≥30% of uncovered struts at 3-month follow-up. Clinical outcomes were the occurrence of target vessel failure (TVF) and major adverse cardiac and cerebrovascular events (MACCE) at 5-year follow-up. RESULTS: LUS occurred in 31 patients (34.4%) regardless of stent platform. At 5 years, no differences were observed in the rate of TVF (12.7% vs. 13.4%; p = 0.91) and MACCE (23.9% vs. 24.9%; p = 0.88) between the two groups. At multivariate logistic regression, plaque rupture, mean lumen diameter, proximal reference vessel area, and maximum stent deployment pressure were independent predictors of LUS. CONCLUSIONS: LUS are a frequent finding in complex coronary lesions treated with thin-struts DES, especially in the presence of plaque rupture. However, in this study, no significant safety signal related to LUS emerged in long-term follow-up.

ABSTRACT

STUDY DESIGN: To compare arterial inflammation (AI) between people living with HIV (PLWH) and uninfected people as assessed by 18F-Fluorodeoxyglucose (18F-FDG)-positron emission tomography (PET). METHODS: We prospectively enrolled 20 PLWH and 20 uninfected people with no known cardiovascular disease and at least 3 traditional cardiovascular risk factors. All patients underwent 18F-FDG-PET/computed tomography (CT) of the thorax and neck. Biomarkers linked to inflammation and atherosclerosis were also determined. The primary outcome was AI in ascending aorta (AA) measured as mean maximum target-to-background ratio (TBRmax). The independent relationships between HIV status and both TBRmax and biomarkers were evaluated by multivariable linear regression adjusted for body mass index, creatinine, statin therapy, and atherosclerotic cardiovascular 10-year estimated risk (ASCVD). RESULTS: Unadjusted mean TBRmax in AA was slightly higher but not statistically different (P = .18) in PLWH (2.07; IQR 1.97, 2.32]) than uninfected people (2.01; IQR 1.85, 2.16]). On multivariable analysis, PLWH had an independent risk of increased mean log-TBRmax in AA (coef = 0.12; 95%CI 0.01,0.22; P = .032). HIV infection was independently associated with higher values of interleukin-10 (coef = 0.83; 95%CI 0.34, 1.32; P = .001), interferon-γ (coef. = 0.90; 95%CI 0.32, 1.47; P = .003), and vascular cell adhesion molecule-1 (VCAM-1) (coef. = 0.75; 95%CI: 0.42, 1.08, P < .001). CONCLUSIONS: In patients with high cardiovascular risk, HIV status was an independent predictor of increased TBRmax in AA. PLWH also had an increased independent risk of IFN-γ, IL-10, and VCAM-1 levels.

ABSTRACT

Even if un to improve long-term prognosis, balloon aortic valvuloplasty (BAV) may be useful in selected patients with symptomatic severe aortic stenosis either as a bridge to surgical or transcatheter valve replacement (aortic valve replacement [AVR] or transcatheter aortic valve implantation [TAVI]) or as a triage strategy for patients with uncertain indications. International guidelines recommend BAV as: a "bridge" to AVR/TAVI, a "trial" in patients with undetermined symptoms, or a "bridge-to-decision" in case of comorbidities. However, in clinical practice, BAV is also used as a palliative measure to improve hemodynamics and quality of life in many patients who are excluded from AVR/TAVI. Finally, BAV is often performed during TAVI to facilitate prosthesis delivery, optimize frame expansion, or for bioprosthetic valve fracture in selected valve-in-valve procedures. Technical innovations, which allow for a mini-invasive approach via transradial access and pacing delivered through the wire, have led to a decrease in complications over time.

ABSTRACT

Transcatheter aortic valve implantation has become a valid alternative to surgical aortic valve replacement for patients with symptomatic severe aortic stenosis, regardless of baseline surgical risk. The incidence of periprocedural complications has steadily declined over the years, thanks to technical advancement of transcatheter heart valves, delivery systems, and increased operators' experience. Beyond the most common periprocedural complications, there are a few uncommon but potentially severe complications that more often occur during follow-up, although they may also arise in the periprocedural phase. Stroke, infective endocarditis, valve thrombosis, and cognitive decline are among them. In this brief review, we describe the incidence, predictive factors, and potential preventive measures for those events.

ABSTRACT

AIMS: Due to bioprosthetic valve degeneration, aortic valve-in-valve (ViV) procedures are increasingly performed. There are no data on long-term outcomes after aortic ViV. Our aim was to perform a large-scale assessment of long-term survival and reintervention after aortic ViV. METHODS AND RESULTS: A total of 1006 aortic ViV procedures performed more than 5 years ago [mean age 77.7 ± 9.7 years; 58.8% male; median STS-PROM score 7.3% (4.2-12.0)] were included in the analysis. Patients were treated with Medtronic self-expandable valves (CoreValve/Evolut, Medtronic Inc., Minneapolis, MN, USA) (n = 523, 52.0%), Edwards balloon-expandable valves (EBEV, SAPIEN/SAPIEN XT/SAPIEN 3, Edwards Lifesciences, Irvine, CA, USA) (n = 435, 43.2%), and other devices (n = 48, 4.8%). Survival was lower at 8 years in patients with small-failed bioprostheses [internal diameter (ID) ≤ 20 mm] compared with those with large-failed bioprostheses (ID > 20 mm) (33.2% vs. 40.5%, P = 0.01). Independent correlates for mortality included smaller-failed bioprosthetic valves [hazard ratio (HR) 1.07 (95% confidence interval (CI) 1.02-1.13)], age [HR 1.21 (95% CI 1.01-1.45)], and non-transfemoral access [HR 1.43 (95% CI 1.11-1.84)]. There were 40 reinterventions after ViV. Independent correlates for all-cause reintervention included pre-existing severe prosthesis-patient mismatch [subhazard ratio (SHR) 4.34 (95% CI 1.31-14.39)], device malposition [SHR 3.75 (95% CI 1.36-10.35)], EBEV [SHR 3.34 (95% CI 1.26-8.85)], and age [SHR 0.59 (95% CI 0.44-0.78)]. CONCLUSIONS: The size of the original failed valve may influence long-term mortality, and the type of the transcatheter valve may influence the need for reintervention after aortic ViV.

ABSTRACT

What the article teaches. Suprasternal (SS) access to the innominate artery is an easy and very safe approach for transcatheter aortic valve implantation (TAVI) when transfemoral (TF) access is not feasible. How it will impact practice. In experienced hands, SS TAVI could become the preferred alternative approach for non-TF TAVI. What new research/study would help answer the question posed. The hypothesis of superior safety of SS access for TAVI in comparison with other non-TF approaches should be investigated in dedicated studies.

ABSTRACT

OBJECTIVES: To evaluate the long-term impact of coronary artery disease (CAD) and heart team-guided incomplete coronary revascularization in patients undergoing transcatheter aortic valve implantation (TAVI). BACKGROUND: Revascularization strategy of CAD diagnosed with routine coronary angiography before TAVI is uncertain. METHODS: Five hundred and forty consecutive TAVI patients were classified as having CAD or normal coronary arteries (no-CAD). Within the CAD group, patients were further classified as those with complete (CR) versus incomplete revascularization (IR). Revascularization strategy was guided by the Heart Team following an algorithm largely based on current guidelines. Main outcome of interest was the incidence of 5-year cardiovascular (CV) death. RESULTS: Prevalence of CAD was 53.9%. CAD patients showed significantly lower left ventricular ejection fraction (LVEF: 55.8 ± 13.4% CAD vs. 61.4% ± 12.1 no-CAD, p < .0001), lower gradients, and larger ventricular volumes in comparison with the no-CAD group. Within the CAD group, 138 patients (47.4%) received CR and 153 (52.6%) IR. In-hospital mortality was 3.9%, without significant difference between groups (4.0% no-CAD vs. 3.8% CAD, p = .88; 2.9% CR vs. 4.6% IR, p = .45). Median follow-up was 57.8 months. Five-year survival free from CV death was 79.6% in the CAD versus 77.9% in the no-CAD group (p = .98), and 84.3% in the CR versus 74.3% in the IR groups (p = .25). These results were confirmed excluding patients with previous revascularization. At multivariable analyses, presentation with acute coronary syndrome (ACS) was significantly associated with 5-year CV death. CONCLUSIONS: CAD is frequent in patients undergoing TAVI but portends an adverse prognosis only when presenting with ACS. Heart-team directed complete or reasonably incomplete revascularization was associated with comparable outcomes.
