Aortic valve replacement (AVR) in patients with a small aortic annulus is a challenging issue. The importance of prosthesis–patient mismatch (PPM) post aortic valve replacement (AVR) is controversial but has to be avoided. Many studies support the fact that PPM has a negative impact on short and long term survival. In order to avoid PPM, aortic root enlargement may be performed. Alternatively and keeping in mind that often some comorbidities are present in old patients with small aortic root, the Perceval S suturelles valve implantation could be a perfect solution. The Perceval sutureless bioprosthesis provides reasonable hemodynamic performance avoiding the PPM and providing the maximum of aortic orifice area. We would like to see in the near future the role of the aortic root enlargement techniques in the era of surgical implantation of the sutureless valve (SAVR) and the transcatheter valve implantation (TAVI).

Objective For elderly patients with symptomatic aortic valve stenosis, aortic valve replacement with tissue valves is still the treatment of choice. Stentless valves were introduced to clinical practice for better hemodynamic features as compared with stented tissue valves. However, the implantation is more complex and time demanding, especially in minimal invasive aortic valve replacement. We present our clinical data on 22 patients having received a sutureless ATS 3f Enable aortic bioprosthesis via partial upper sternotomy. Methods The procedure was performed using CPB with cardioplegic arrest. After resection of the stenotic aortic valve and debridement of the annulus, the valve was inserted and released. Mean age was 79 years, and mean logistic Euroscore was 13. Subvalvular myectomy was performed in two patients. Prosthetic valve sizes were 19 mm (n = 1), 21 mm (n = 7), 23 mm (n = 6), 25 mm (n = 6), and 27 mm (n = 2). Results Implantation of the valve required 10 ± 6 minutes. Cardiopulmonary bypass and aortic crossclamp time were 87 ± 16 and 55 ± 11 minutes, respectively. Early mortality (<90 days) was 9% (2 patients). No paravalvular leakage was detected intraoperatively or in follow-up echocardiography. The mean transvalvular gradients were 9 ± 6 mm Hg at discharge and 8 ± 2 mm Hg at 1-year follow-up. Conclusions Sutureless valve implantation via partial sternotomy is feasible and safe with the ATS 3f Enable bioprosthesis. Reduction of cardiopulmonary bypass and aortic crossclamp time seems possible with increasing experience. Hemodynamic data are very promising with low gradients at discharge and after 12 month. Sutureless valve implantation via minimal invasive access may be an alternative treatment option for elderly patients with high comorbidity.

Aortic valve replacement is a gold standard in the treatment of patients with severe aortic stenosis or combined aortic pathology. However, aortic valve pathology is often associated with a narrow aortic orifice, particularly in patients with severe aortic stenosis. In 1978, Rahimtoola first described the term of prosthesis-patient mismatch. He noted that effective orifice area of the prosthesis is smaller than that of the native valve. To minimize this complication, there are several surgical strategies: aortic root enlargement (ARE), implantation of a frameless biological prosthesis in the native position, neocuspidalization procedure, Ross procedure, aortic root replacement with xenograft or homograft. ARE is an excellent option, however, some authors outline additional perioperative risks. The aim. To analyze immediate results of ARE during isolated aortic valve replacement and in cases when it is combined with other heart pathologies. Materials and methods. Our study included 63 patients who underwent ARE. Isolated aortic valve replacement was performed in the majority of cases, but often aortic root replacement procedure was combined with coronary artery bypass grafting. Results and discussion. One of 63 patients died (hospital mortality 1.6%) at an early hospital stage (30 postoperative days). Measurement of the aortic valve ring was performed by two methods, through preoperative echocardiography and perioperative measurement using a valve sizer. However, perioperative dimension was chosen as the basis for the calculations. In 62 patients, the perioperative diameter of the aortic valve ring ranged from 19 to 23 mm, only one patient had a diameter of 24 mm. According to our findings, ARE enabled to achieve an average aortic ring size increase of 2.68 cm2 (from 1.5 to 3.4 cm2) and to prevent prosthesis-patient mismatch in 42 (66.7%) cases. Conclusions. Prosthesis-patient mismatch is considered a serious complication in the postoperative period. Narrow aortic root is a common pathology that should be considered during surgery. ARE is a safe procedure and is not associated with an increased risk of mortality and complications.

Abstract OBJECTIVES Concomitant aortic root enlargement (ARE) at the time of surgical aortic valve replacement can be performed to avoid patient–prosthesis mismatch, an important predictor of adverse long-term outcome. METHODS We performed a single-centre, retrospective analysis of 4120 patients receiving isolated aortic valve replacement, of whom 171 (4%) had concomitant ARE between January 2005 and December 2015. The analysis of postoperative outcome and early mortality was performed. Owing to inequality of the groups, patients were matched 1:1. RESULTS The mean age of all 4120 patients was 68.8 ± 10.5 years, and comorbidities were equally balanced after matching. The mean aortic cross-clamp time, cardiopulmonary bypass time and total operative time were prolonged by 19, 20 and 27 min in the ARE group, respectively. Early mortality was not statistically significantly different with 1.4% in the surgical aortic valve replacement and 1.8% in the ARE group. Postoperative complications were <5% in all matched 338 patients: bleeding (3% vs 3%), pericardial effusion (3.0% vs 4.2%), sternal instability (1.8% vs 0%) and sternal wound infection (3.0% vs 1.2%). A significant higher number of patients had respiratory failure after ARE (unmatched: 17.1% vs 9.9%, P < 0.001; matched: 18.3% vs 9.5%, P = 0.028). Factors independently associated with overall mortality were age [hazard ratio (HR) 1.71], chronic obstructive pulmonary disease (HR 1.47), diabetes (HR 1.82), atrial fibrillation (HR 2.14) and postoperative respiratory failure (HR 2.84). CONCLUSIONS ARE can be performed safely in experienced centres with no significant increase in the risk of early postoperative surgical complications and early mortality. However, the surgeon and the intensive care unit team should be aware of an increased risk for postoperative respiratory failure in ARE patients.

Familial homozygous hypercholesterolemia is a rare disease with diverse clinical presentations ranging from premature ischemic heart disease to aortic root stenosis but rarely presents with anginal symptoms due to supravalvular and valvular aortic stenosis. We report a 19-year-old male patient with familial homozygous hypercholesterolemia with progressive supravalvular and valvular aortic stenosis that ultimately required aortic root enlargement and aortic valve replacement using a mechanical prosthesis, despite aggressive medical therapy. Surgical importance of this rare condition is highlighted.
