Size Matter

Background: The long-term performance of prostheses in the small aortic root is still unclear. Methods: Patients who received a 21 mm or smaller aortic valve between 2000–2018 were retrospectively analyzed. Propensity matching was used in order to account for baseline differences in 19 mm vs. 21 mm valve subgroups. Results: Survival at 10 years was 55.87 ± 5.54% for 19 mm valves vs. 57.17 ± 2.82% for 21 mm ones in the original cohort (p = 0.37), and 58.69 ± 5.61% in 19 mm valve recipients vs. 53.60 ± 5.66% for 21 mm valve subgroups in the matched cohort (p = 0.55). Smaller valves exhibited significantly more patient–prothesis mismatch (PPM) than larger ones (87.30% vs. 57.94%, p < 0.01). All-cause mortality was affected by PPM at 10 years (52.66 ± 3.28% vs. 64.38 ± 3.87%, p = 0.04) in the unmatched population. This difference disappeared, however, after matching: survival at 10 years was 51.82 ± 5.26% in patients with PPM and 63.12 ± 6.43% in patients without PPM. (p = 0.14) Conclusions: There is no survival penalty in using 19 mm prostheses in the small aortic root in the current era. Although PPM is more prevalent in smaller sized valve recipients, this does not translate into reduced survival at 10 years of follow-up.

Small Aortic Root

<strong>Background:</strong> The management of a small aortic root at the time of aortic valve replacement is controversial. In cases in which the aortic root is very small the choice of aortic valve type and of root-enlargement method is difficult. The technical challenge of the small aortic root has instigated the creation of methods for annular enlargement. Severe mismatch as a predictor of overall 30-day mortality or midterm mortality reports about long-term results of aortic valve replacement using autologous pericardial patch are scarce. Moreover, no reports about patient series are present in the English medical literature. This retrospective study was designed to address this gap in evidence. <br /><strong>Methods:</strong> Twenty consecutive patients undergoing aortic valve replacement (with or without mitral valve replacement and/or coronary artery bypass grafting) at Başkent University Adana Medical Center between June 30, 1999 and April 10, 2006 were retrospectively evaluated. All clinical and echocardiographical data belonging to this population were specified. Their perioperational data were assessed. <br /><strong>Results:</strong> Twenty patients operated using the Manouguian technique for narrow aortic root from June 1999 to April 2006 were followed for 8.54 ± 3.35 years. Fourteen patients were alive at the end of the follow-up. Six patients had died. Early mortality rate was 5% and late mortality after 8.54 ± 3.35 years was 30%. Late mortality related to cardiac reasons was 5%. Only one death could be attributed to a cardiac cause which occured in a 36-year-old male patient 3 years and 6 months after the operation. 70% of the patients were alive after a mean follow-up period of 8.54 ± 3.35 years.<br /><strong>Conclusion:</strong> The main finding of the present study is that aortic root enlargement using untreated fresh autologous pericardium in Manouguian type operations is a durable option, especially in conditions when homograft or stentless valve use is difficult or economically not feasible. We found that no patient had aneurysmal dilatation or mitral regurgitation after a mean follow-up of 8.54 ± 3.35 years with autologous untreated pericardium as the enlargement patch.

Stone matrix asphalt (SMA) and Superpave® represent relatively new mix design technologies in the United States. Therefore, a condition survey was conducted of mixes that had been in service for several years to evaluate the long-term performance of SMA and Superpave projects. This study is a follow-up to a 1995 review of SMA projects and a 1998 review of Superpave projects. Both SMA and Superpave are acknowledged to be rut-resistant mixes, and this resistance was shown to be the case during this project review. However, a significant amount of cracking occurred early in the life of some of these mixtures. Overall, the SMA mixtures appeared to be more durable than the Superpave mixtures evaluated. The SMA mixtures have been in place about 2½ years longer than the Superpave mixtures, but the overall condition is about the same. Some of the primary conclusions from the survey are as follows: both SMA and Superpave mixtures were shown to be rut-resistant even when placed on facilities with high traffic volume; much of the observed cracking, especially load cracking, appeared to be more related to problems other than mix design or material properties; and SMA mixtures can be expected to last longer than Superpave mixtures before reaching the same condition level.

Valve Sparing

Objective: Valve-sparing root replacement is commonly used for management of aortic root aneurysms in elective setting, but its technical complexity hinders its broader adoption for acute Type-A Aortic Dissection (ATAAD). The Florida Sleeve (FS) procedure is a simplified form of valve sparing aortic root reconstruction that does not require coronary reimplantation. Here, we present our outcomes of the Florida Sleeve (FS) repair in patients with dilated roots in the setting of an ATAAD. Methods: We retrospectively reviewed 24 consecutive patients (2002-2018) treated with FS procedure for ATAAD. Demographic, operative, and postoperative outcomes were queried from our institutional database. Long term follow-up was obtained from clinic visits for local patients, and with telephone and telehealth measures otherwise. Results: Mean age was 49 ± 14 years with 19 (79%) males. Marfan syndrome was present in 4 (16.7%) patients and 14 (58.3) had ≥2+ aortic insufficiency (AI). Nine (37.2%) had preoperative mal-perfusion or shock. The FS was combined with hemi-arch replacement in 15 (62.5%) patients and a zone-2 arch replacement in 9 (37.5%) patients. There were 2 (8.3%) early postoperative mortalities. Median follow-up period was 46 months (range; 0.3-146). The median survival of the entire cohort was 143.4 months. One patient (4.2%) required redo aortic valve replacement for unrelated aortic valve endocarditis at 30 months postoperatively. Conclusion: FS is simplified and reproducible valve-sparing root repair. In appropriate patients, it can be applied safely in acute Stanford type-A aortic dissection with excellent early and long-term results.

Retrospective Multicenter Study

Introduction: The objective of this retrospective multicenter study is to report the initial long-term performance results after percutaneous exclusion of the LAA with the endo-epicardial Lariat device to prevent AF-related thromboembolic events. Methods and results: Patients with successful LAA ligation and at least 1-year follow-up were analyzed (N=355). At 1 year, TEE follow-up was present in 172 patients. A leak was defined as presence of flow into the LAA as assessed by TEE. At 6 months, 19 (11%) patients had a leak; 2 strokes occurred: 1 in a patient without a leak and 1 associated with mesenteric ischemia in a patient without a known acute leak, who died before repeat TEE could be performed. At 12 months, 34 (20%) patients had a leak; 6 patients developed a neurological event (5 strokes and 1 TIA), 4 in patients with a leak, 2 in patients without a leak. 3% were followed-up for more than one 1 year (with a mean of 21±9 months). 1 additional thromboembolic event (TIA) occurred 14 months post-implant in a patient without anticoagulation and with a partially excluded LAA (stump), although no leak or thrombus were detected on standard TEE. Among patients with a leak (36% of those with long-term follow-up), 75% were on long-term anticoagulation and no additional TE events were detected. Out of 355 patients, 9 (2.5%) patients had a neurological event: 4 with a leak, 4 without a leak and 1 in a patient where TEE was not repeated. Considering those with known LAA status, thromboembolic events were more common in patients with a leak (4/34 vs 4/136; RR 4, 95% CI 1.1-15.4). Conclusion: In this multicenter experience with the Lariat device, the rate of leaks was high (20% of those with TEE follow-up at 1 year). Thromboembolic events were not rare (overall, 2.5%), and occurred more frequently in patients with a leak (RR 4).

Abstract Aims His-bundle pacing (HBP) combined with atrioventricular node (AVN) ablation has been demonstrated to be effective in patients with atrial fibrillation (AF) and heart failure (HF) during medium-term follow-up and there are limited data on the risk analysis of adverse prognosis in this population. In this study, we aimed to evaluate the long-term performance of HBP following AVN ablation in AF and HF. Methods and results From August 2012 to December 2017, consecutive AF patients with HF and narrow QRS who underwent AVN ablation and HBP were enrolled. The clinical and echocardiographic data, pacing parameters, all-cause mortality, and heart failure hospitalization (HFH) were tracked. A total of 94 patients were enrolled (age 70.1 ± 10.5 years; male 57.4%). Acute HBP were achieved in 89 (94.7%) patients with successful permanent HBP combined with AVN ablation in 81 (86.2%) patients. Left ventricular ejection fraction (LVEF) improved from 44.9 ± 14.9% at baseline to 57.6 ± 12.5% during a median follow-up of 3.0 (IQR: 2.0–4.4) years (P &lt; 0.001). Heart failure hospitalization or all-cause mortality occurred in 21 (25.9%) patients. The LVEF ≤ 40%, pulmonary artery systolic pressure (PASP) ≥40 mmHg, or serum creatinine (Scr) ≥97 μmol/L at baseline was significantly associated with higher composite endpoint of HFH or death (P &lt; 0.05). The His capture threshold was 1.0 ± 0.7 V/0.5 ms at implant and remained stable during follow-up. Conclusion His-bundle pacing combined with AVN ablation was effective in patients with AF and drug-refectory HF. High PASP, high Scr, or low LVEF at baseline was independent predictors of composite endpoint of all-cause mortality or HFH.
