RESUMEN

AIMS: Septal myectomy is the treatment of choice for hypertrophic obstructive cardiomyopathy (HOCM). Around 30-60% of patients with HOCM have a secondary mitral valve regurgitation due to systolic anterior motion (SAM). We report our experience with extended septal myectomy and its impact on the incidence of concomitant mitral valve procedures. METHODS: This is a retrospective study on 84 patients who underwent SM from January 2008 to February 2022. Surgical procedure was performed according to the concept of 'extended myectomy' described by Messmer in 1994. Follow-up outcomes in terms of survival, hospital admissions for heart failure or MV disease, cardiac reoperations, and pacemaker (PMK) implantation were recorded. RESULTS: Mean age was 61 ±â€Š15 years. Mitral valve surgery was performed in seven cases (8%); particularly only one patient without degenerative mitral valve disease underwent mitral valve surgery, with a plicature of the posterior leaflet. In-hospital mortality was 5%. Mitral valve regurgitation greater than mild was present in four patients (5%) at discharge. Twelve-year survival was 78 ±â€Š22%. Cumulative incidence of rehospitalization for heart failure and rehospitalization for mitral valve disease was 10 ±â€Š4 and 2.5 ±â€Š2.5%, respectively. PMK implantation was 5% at discharge, with a cumulative incidence of 15 ±â€Š7%. Freedom from cardiac reoperations was 100%. CONCLUSION: Septal myectomy for HOCM is associated with good outcomes. Although concomitant surgery on the mitral valve to address SAM and associated regurgitation has been advocated, these procedures were needed in our practice only in patients with intrinsic mitral valve disease. Adequate myectomy addresses the underlying pathophysiology in most patients.

RESUMEN

BACKGROUND: Procedural volume has been documented as an important contributor to operative outcomes for most complex surgical procedures. Mitral valve repair (MVRep) has been associated with excellent results, and it is increasingly adopted in many cardiac surgical centers. We sought to investigate if procedural volume is associated with better clinical long-term outcomes after MVRep. METHODS: We analyzed the 10-year outcomes after MVRep by procedural volume for each cardiac surgery center in an Italian Region, Lazio, during the last 15 years, using a regional administrative dataset. RESULTS: Between 2006 and 2020, 4961 patients were treated in seven cardiac surgery centers for an isolated mitral valve surgery (2677 underwent MVRep). At multivariate analysis, mitral valve replacement (MVR) (vs. MVRep) resulted one of the independent predictors of 30-day mortality [adjusted odds ratio (OR) 3.40; 95% confidence interval (CI) 1.96-5.90; P  < 0.0001]. Notably, a clear association between hospital volume of mitral valve surgery (>40 per year) and high rate of MVRep (>50%) was found. At 10 years, the incidence of mortality and the rate of death and rehospitalization for heart failure after MVRep were significantly lower in high-volume vs. low-volume hospitals. CONCLUSION: Our data suggest that hospital volume is associated with a high rate of MVRep and long-term benefits in terms of mortality and recurrence of heart failure.

RESUMEN

Epigenetic modifications play a fundamental role in the progression of coronary artery disease (CAD). This panoramic review aims to provide an overview of the current understanding of the epigenetic mechanisms involved in CAD pathogenesis and highlights the potential implications for personalized medicine approaches. Epigenetics is the study of heritable changes that do not influence alterations in the DNA sequence of the genome. It has been shown that epigenetic processes, including DNA/histone methylation, acetylation, and phosphorylation, play an important role. Additionally, miRNAs, lncRNAs, and circRNAs are also involved in epigenetics, regulating gene expression patterns in response to various environmental factors and lifestyle choices. In the context of CAD, epigenetic alterations contribute to the dysregulation of genes involved in inflammation, oxidative stress, lipid metabolism, and vascular function. These epigenetic changes can occur during early developmental stages and persist throughout life, predisposing individuals to an increased risk of CAD. Furthermore, in recent years, the concept of personalized medicine has gained significant attention. Personalized medicine aims to tailor medical interventions based on an individual's unique genetic, epigenetic, environmental, and lifestyle factors. In the context of CAD, understanding the interplay between genetic variants and epigenetic modifications holds promise for the development of more precise diagnostic tools, risk stratification models, and targeted therapies. This review summarizes the current knowledge of epigenetic mechanisms in CAD and discusses the fundamental principles of personalized medicine.

RESUMEN

BACKGROUND: Transcatheter aortic valve implantation (TAVI) is emerging as an appealing management strategy for patients with severe aortic stenosis at intermediate, high or exceedingly high risk, but its risk-benefit profile in younger patients is less certain. We aimed to explore the outlook of patients aged 70 years or less and undergoing TAVI at 2 high-volume Italian institutions. METHODS: We retrospectively collected baseline, imaging, procedural and outcome features of patients with age ≤70 years in whom TAVI was attempted at participating centers between 2012 and 2021. Non-parametric tests and bootstrap resampling were used for inferential purposes. RESULTS: A total of 39 patients were included, out of >3000 screened with heart team involvement and >1500 receiving TAVI. Most common or relevant indications for TAVI reduced life expectancy (e.g. cardiogenic shock or severe left ventricular systolic dysfunction), chronic obstructive pulmonary disease, morbid obesity, active or recent extra-cardiac cancer, porcelain aorta, neurologic disability, cirrhosis, or prior surgical aortic valve replacement, as well as extreme cachexia, and Hutchinson-Gilford progeria. At least two contemporary high-risk features were present in most cases. Transapical access was used in 5 (12.8%) cases, and a sheathless approach in 15 (38.5%). A variety of devices were used, including both balloon- and self-expandable devices. Clinical outcomes were satisfactory, despite the high-risk profile, at both short- and mid-term, with no in-hospital death, and 5.1% (95% confidence interval 0-12.8%) mortality at a median follow-up of 15 months (minimum 1; maximum 85). Notably, no case of significant valve deterioration requiring reintervention occurred. CONCLUSIONS: In carefully selected patients with 70 years or less of age and prohibitive risk for surgery or reduced life expectancy, TAVI represents a safe option with a favorable mid-term survival and low rate of adverse events.

RESUMEN

OBJECTIVES: The role of the underlying etiology in isolated tricuspid valve surgery has not been investigated extensively in current literature. Aim of this study was to analyse outcomes of patients undergoing surgery due to endocarditis compared to other pathologies. METHODS: The SURTRI study is a multicenter study enrolling adult patients who underwent isolated tricuspid valve surgery (n = 406, 55 ± 16 y.o.; 56% female) at 13 international sites. Propensity weighted analysis was performed to compare groups (IE group n = 107 vs Not-IE group n = 299). RESULTS: No difference was found regarding the 30-day mortality (Group IE: 2.8% vs Group Not-IE = 6.8%; OR = 0.45) and major adverse events. Weighted cumulative incidence of cardiac death was significantly higher for patients with endocarditis (p = 0.01). The composite endpoint of cardiac death and reoperation at 6 years was reduced in the Group IE (63.2 ± 6.8% vs 78.9 ± 3.1%; p = 0.022). Repair strategy resulted in an increased late survival even in IE cases. CONCLUSIONS: Data from SURTRI study report acceptable 30-day results but significantly reduced late survival in the setting of endocarditis of the tricuspid valve. Multi-disciplinary approach, repair strategy and earlier treatment may improve outcomes.

RESUMEN

In the complex spectrum of coronary anomalies, the origin of the left coronary artery from the right sinus of Valsalva with intramural course could represent a catastrophic life-threatening condition leading to extensive myocardial infarction and sudden cardiac death, especially in young athletes. We report the case of a young female athlete with anomalous left coronary artery from the opposite sinus who survived a major non-ST-elevation myocardial infarction during the eighth kilometer of a running race. It was successfully treated by creating a neo-ostium of the left coronary artery in the left sinus at the point at which the artery left the aortic wall.

RESUMEN

In patients with advanced heart failure (HF), left ventricular assist devices (LVADs) have demonstrated to be effective in improving the quality of life and reducing further hospitalizations. Although uncommon, LVAD outflow graft obstruction (OGO) is a potentially life-threatening complication and percutaneous treatment has been proposed as a standard intervention strategy in such cases. We report the case of a 69 year old man admitted due to LVAD failure causing unstable HF. Past medical history included percutaneous intervention on the outflow graft with stent implantation one year before. The patient was under chronic treatment with vitamin K antagonists (VKA). Emergent percutaneous angiography was performed, showing recurrent OGO due to thrombosis located at a kinking site, distally to the previously treated segment. Using distal anchoring technique, a balloon-expandable 10 × 79 mm endoprosthesis (GORE® Viabahn® VBX) was effectively positioned and post-dilated. Final angiography confirmed the patency of the stent implanted one-year before. Despite the procedure succeeding in restoring LVAD function, the patient died due to septic shock ten days after. Our case suggests that recurrent OGO can be effectively treated with percutaneous redo and that long-term stent patency can be achieved with a standard antithrombotic treatment, despite further thrombotic events in other segments of the graft are still possible (especially at the kinking site). Moreover, other noncardiac conditions as infective complications, can dramatically impact the clinical course and lead to unfavorable outcomes.

RESUMEN

OBJECTIVES: The interest in isolated tricuspid valve disease has rapidly increased recently. However, clinical trials and registry data are rare in the surgical literature. This study aimed to describe the early and long-term outcomes of a real-world experience in isolated tricuspid procedures comparing repair and replacement strategies. METHODS: The Surgical-Tricuspid study is a multicentre retrospective study that enrolled adult patients who had undergone isolated tricuspid valve surgery at 13 international sites. Propensity score-matched analysis was used to compare repair versus replacement. RESULTS: A cohort of 426 patients was enrolled [mean age: 55 (16) years; 56% female]. After matching, 175 comparable pairs were analysed. Preoperative left ventricular ejection fraction was 55(9) vs 56(9) (P = 0.8) while moderate-severe tricuspid regurgitation was present in 95% of cases. The 30-day mortality rate was 4.0% vs 8.0% in the repair and replacement groups, respectively (P = 0.115). The rates of re-exploration for bleeding (6.9% vs 13.1% P = 0.050), permanent pacemaker implantation (5.1% vs 12.0%; P = 0.022) and blood transfusion (46% vs 62%; P = 0.002) were higher in the replacement group. Cumulative survival rates at 3, 5 and 7 years in the repair group were 84 (3)%, 75 (4)% and 56 (9)% vs 71 (4)%, 66 (5)% and 58 (5)% in the replacement group (P = 0.001) while cumulative incidence for reoperation at 10 years did not differ between groups [repair 10 (1)% vs replacement 9 (1)%; P = 0.469]. CONCLUSIONS: The data from the Surgical-Tricuspid study reported a high risk for patients undergoing tricuspid surgery. Isolated valve repair offered reduced early and late mortality with no difference regarding reoperation rate when compared with replacement.

RESUMEN

BACKGROUND: Aim of this study is to analyse the performances of Clinical Risk Score (CRS) and European System for Cardiac Operative Risk Evaluation (EuroSCORE)-II in isolated tricuspid surgery. METHODS: Three hundred and eighty-three patients (54 ± 16 year; 54% female) were enrolled. Receiver operating characteristic analysis was performed to evaluate the relationship between the true positive fraction of test results and the false-positive fraction for a procedure. RESULTS: Considering the 30-day mortality the area under the curve was 0.6 (95% confidence interval [CI] 0.50-0.72) for EuroSCORE II and 0.7 (95% CI 0.56-0.84) for CRS-score. The ratio of expected/observed mortality showed underestimation when considering EuroSCORE-II (min. 0.46-max. 0.6). At multivariate analysis, the CRS score (p = .005) was predictor of late cardiac death. CONCLUSION: We suggest using both scores to obtain a range of expected mortality. CRS to speculate on late survival.

RESUMEN

BACKGROUND: Isolated tricuspid valve (TV) surgery is a rare procedure generally considered at high risk for perioperative mortality and poor long-term outcomes. Surgical treatment can be performed with either an arrested heart (AH) or beating heart (BH) technique. The aim of this study was to compare the outcomes of isolated tricuspid surgery with 2 different approaches. METHODS: The Surgical-Tricuspid Study is a multicenter international retrospective study enrolling adult patients who underwent isolated TV procedures (n = 406; age 56 ± 16 years; 56% female) at 13 international sites. The AH and BH strategies were performed in 253 and 153 patients, respectively. Propensity score-matched analysis was used to compare groups. RESULTS: After matching, 129 pairs were obtained and analyzed. The 30-day mortality rate was 6.2% versus 5.0% in the AH and BH groups, respectively (P = .9). The rates of acute renal failure requiring replacement therapy (10% versus 3%; P = .02) and stroke (1.6% versus 0%; P = .08) were numerically higher in the AH group. The 6-year survival rate was 67% ± 6% versus 78% ± 5% in the AH and BH groups, respectively (P = .18), whereas freedom from cardiac death was 75% ± 5% versus 84% ± 4% (P = .21). The 6-year composite cardiac end point of cardiac death and reoperation rate was 60% ± 9% versus 86% ± 5% (P = .024) comparing AH-TV replacement and BH-TV repair groups. CONCLUSIONS: Isolated TV surgery performed with a BH strategy is a safe option and resulted in a trend of increased long-term survival and freedom from reoperation compared with the standard AH technique. Patients undergoing BH valve repair had the best long-term outcome.

RESUMEN

In recent years, the treatment of mitral valve disease with robotic surgery has been increasingly successful, having produced excellent postoperative results and significant cost-savings. However, minimal  experience exists with robotic mitral valve repair using transareolar access. We demonstrate mitral valve repair using the DaVinci Robot Xi through a transareolar approach, showing the technical details of our surgical technique.

RESUMEN

Mitral valve repair is typically performed by implanting a ring-like device at the valve annulus to reshape the annulus and to improve leaflet coaptation. In most cases, some additional procedures are needed, including leaflet resection and artificial chordae implantation. However, artificial chordae implantation could be technically challenging and postoperative left ventricular remodeling could increase the risk of recurrent mitral regurgitation. We propose an innovative annular device made of chromo-cobalt, finalized not only to reshape the annulus but also to enable anchoring of leaflets to a fixed intraventricular structure. Durability evaluation of the device was tested by applying eight radial force vectors equally spaced along the ring and related fatigue analysis. To evaluate the efficacy of the mitral valvuloplasty using the tested ring, the device was implanted in five adult swine hearts. Functional analysis of the ring was performed by measuring left ventricular pressure and fluid volume loss, following implantation in normal and dysfunctional mitral valve leaflets. Both fatigue and functional analysis showed satisfactory and promising results in terms of durability and efficacy of mitral valve repair. Because of its favorable durability and functional characteristics this device appears promising and provides good results in terms of valve competence, thus avoiding both manipulations of papillary muscles and interference in left ventricular hemodynamics. However, an in vivo test is mandatory to fully understand the impact of the device on subvalvular apparatus.

RESUMEN

AIMS: Female sex and heart failure (HF) are considered poor prognostic factors for surgery. We aimed to investigate the association between sex and surgical outcomes in patients with ischaemic HF undergoing surgical ventricular reconstruction and coronary artery bypass grafting. METHODS AND RESULTS: From July 2001 to June 2017, 648 patients [111 women (17%) and 537 men (83%)] were referred to our centre. Follow-up continued through June 2018. All patients underwent surgical ventricular reconstruction; coronary artery bypass grafting was performed in 582 patients (90%). Primary outcome was defined as all-cause mortality. Secondary outcome included all-cause mortality or all-cause hospitalization. Women were older (70 vs. 65 years, P < 0.0001) with lower body surface area (1.70 vs. 1.86 m2 , P < 0.0001). Women had more diabetes (36% vs. 24%, P = 0.005) and a higher New York Heart Association classification (Class III/IV 65.7% vs. 47.8%, P = 0.0006), without any significant difference in medical therapy except for a higher use of oral antidiabetic agents in women (P = 0.029). At baseline, the left ventricular (LV) end-diastolic volume index was significantly lower in women [median 107.06 (80.6-127.81) vs. 113. 04 (94.33-135.52) mL/m2 , P = 0.0078] but not the LV end-systolic volume index (ESVI) [median 73.45 (51.93-96.79) vs. 77.03 (60.33-95.71) mL/m2 , P = 0.1393] and the ejection fraction (median 31% vs. 32%, P = 0.150). Women had a higher rate of anterior remodelling (90.9% vs. 79.1%, P = 0.0129), without evidence of differences in mitral valve insufficiency (P = 0.761 for Grade 0 to 4) and mitral surgery (P = 0.810). After surgery, the percentage of reduction in LV ESVI was higher in women than in men (median ΔLV ESVI -42.06 vs. -31.99, P = 0.0003). Mortality within 30 days occurred in 43 patients (6.64%): 12 women (10.81%) and 31 men (5.77%, P = 0.0522). Over a median follow-up of 9.8 years, all-cause mortality occurred in 269 patients (41.64%), without significant difference between women (45.9%) and men (40.7%). There was no evidence of difference of all-cause death between sexes (log-rank = 0.2441). When considering mortality and first hospitalization as competing events, Gray's test showed no difference of cumulative incidence functions (all-cause hospitalization, all-cause death, and combined endpoint) according to sex (P = 0.909, P = 0.445, and P = 0.429, respectively). CONCLUSIONS: In this study, long-term outcomes for women and men with ischaemic HF undergoing complex cardiac surgery were equivalent. Albeit older and more symptomatic, women should not be denied this type of cardiac surgery.

RESUMEN

Left ventricular aneurysms (LVA) are a complication of myocardial infarction, that rarely involve the posterior wall; surgical repair of posterior LVA poses a technical challenge when associated with concomitant mitral regurgitation. We describe a minimally invasive treatment of ischemic MR and concomitant patch exclusion of posterior LVA through a right minithoracotomy. Using a transatrial approach, the aneurysm is closed with a "U" shaped dacron patch, whose base is anchored to the mitral annulus. Two patients were operated by this method with excellent results.

RESUMEN

BACKGROUND: Despite improvements in operative techniques, open thoracoabdominal aortic aneurysm (TAAA) repair is complex and characterized by high mortality and morbidity rate. Less invasive techniques have been developed since 2005 for the treatment of TAAA. Unfortunately, many of these devices require custom fabrication, resulting in delay of many weeks until treatment can be delivered but crucial in critical emergency cases. We present a novel hybrid endovascular and surgical prosthesis, which was tested on five pigs, with the aim of reducing the barrier issues of endovascular therapy in such particular cases. METHODS: The principal characteristic of the proposed hybrid endovascular prosthesis is to combine a proximal and distal stented zones and, in between, a classical surgical blood tied Dacron prosthesis. The device was tested in five pigs where feasibility of implantation and acute postoperative outcomes were evaluated, including bleeding, bowel ischemia, renal function, and peripheral blood perfusion. RESULTS: In all cases, following laparotomy, the endoprosthesis was successfully implanted under fluoroscopy and the surgical prosthesis zone could be easily detected by the radio-opaque markers. No major bleeding or cardiac events occurred throughout preparation and implantation. One hour after prosthesis implantation and surgical anastomoses of all vessels were completed, normal urine output was registered, and no acidosis was detected. CONCLUSIONS: This novel graft has shown ease of endoprosthesis and visceral vessels implantation without the need of thoracotomy or extracorporeal circulation and may be useful in an emergency setting or high risk and complex anatomy TAAA unsuitable for traditional endovascular aneurysm repair, or to avoid an excess waiting time for a "custom made" prosthesis. The great adaptability of this "hybrid" prosthesis in complex anatomy for the majority of TAAA could be important in high-risk patients and in some difficult situations, such as a high risk of imminent rupture.

RESUMEN

OBJECTIVES: Our goal was to analyse a consecutive series of patients with solid organ tumours undergoing coronary artery bypass grafting (CABG) by defining the risk factors for early and long-term outcomes. METHODS: Between 2005 and 2016, a consecutive series of 4079 patients underwent isolated CABG at our institution. Of 103 patients (2.5%) with active malignancy, we enrolled 82 patients (mean age 71 ± 7 years) with solid organ tumours, divided into 4 subgroups: lung (9 patients-11%), gastroenteric (16 patients-20%), urinary (48 patients-58%) and other solid tumours (9 patients-11%). A deterministic record linkage between the clinical database and the National Hospital Information System allowed identification of long-term survival rates and freedom from major adverse cardiovascular events (acute myocardial infarction, repeated admissions for percutaneous coronary intervention and heart failure). RESULTS: The most common forms of cancer were prostate, colon and carcinoma of the lung. Compared to patients without cancer, patients with neoplasms were significantly older and had a higher rate of comorbidities, without significant differences among the cancer subgroups. The 30-day mortality rate was significantly higher in patients with cancer compared to those without cancer (4.9% vs 1.8%). However, on logistic regression analysis, cancer was an independent risk factor for postoperative pulmonary dysfunction but not for in-hospital death. The median follow-up time was 58 ± 12 months. The overall 5-year survival rate was 60% [95% confidence interval (CI) 47-71%], with a dismal 32% (95% CI 5-65%) survival rate among patients who had lung tumours only. The 5-year freedom from major adverse cardiovascular events was 64% (95% CI 52-74%), without significant differences among subgroups, and was comparable to that of the non-cancer population. Resolution of coronary heart disease allowed safe cancer surgical resection in 80% of the population. CONCLUSIONS: Based on the results from the present study, CABG should not be denied to patients with solid organ tumours by claiming a worse prognosis or less graft durability. Further studies with larger numbers are warranted.

RESUMEN

Surgical management of patients affected by structural valve deterioration of bioprostheses in tricuspid valve position represents a challenge. Furthermore, transcatheter valve-in-valve implantation (TVIVI) recently emerged as an interesting option in high-risk surgical patients. When surgery is performed, replacement of the dysfunctional tricuspid bioprosthesis could be a difficult procedure due to the risk of heart rupture during the prosthesis removal. Herein we report the case of a 52-year-old female patient in which a transcatheter TVIVI was successfully performed under direct vision as a bailout strategy due to the impossibility of bioprosthesis removal.

RESUMEN

OBJECTIVES: Transcatheter aortic valve implantation with a transaortic approach (TAo-TAVI) is an alternative to transapical or femoral access. We studied the procedural and midterm efficacy and safety of TAo-TAVI with Edwards Sapien XT and Medtronic CoreValve devices. METHODS: Among 901 patients receiving TAVI since 2006, 265 consecutive patients underwent TAo-TAVI between January 2011 and September 2014. Procedural and midterm results were evaluated according to Valve Academic Research Consortium-2 criteria. RESULTS: The mean age was 83 ± 5 years. Sapien XT and CoreValve were used in 191 (72.1%) and 74 (27.9%) patients, respectively. Full sternotomy made elective concomitant off-pump coronary artery bypass grafting possible in 38 patients (14.3%) with severe coronary artery disease unsuitable for percutaneous coronary intervention. The device success rate was 95.5%. Postprocedural paravalvular leak ≥2/4 was observed in 16 patients (6.4%). Emergency open chest surgery was required in 10 patients (3.8%) (3 aortic dissections, 3 valve embolizations, 2 LMCA occlusions, 1 aortic annulus rupture and 1 aortic rupture). Cerebrovascular accidents occurred in 3 patients (1.1%). Transfusions ≥4 units were required in 36 patients (13.6%). New pacemakers were implanted in 26 patients (9.8%). Thirty-day and 1-year mortality were 8.7% and 16.2%, respectively. Mean follow-up duration was 24 ± 6 months. At 3 years, freedom from all-cause death was 80% ± 4%. New York Heart Association class

RESUMEN

Coronary artery aneurysms (CAAs) are rare lesions in which the optimal management is poorly defined. We present a series of three patients with diffuse symptomatic coronary artery disease and giant CAAs, on the circumflex branch (6 × 5 cm - Patient 1), on the proximal right coronary artery (5 × 6 cm - Patient 2) and on the proximal left anterior descending (LAD) (4 × 5 cm - Patient 3). Standard coronary artery bypass grafting (LIMA-on-LAD plus sequential saphenous vein) and associated CAA exclusion by proximal and distal ligation was performed according to the coronary anatomy. Six month follow-up computed tomography scan control showed complete exclusion of the CAA in all three patients.

RESUMEN

BACKGROUND: The Ross procedure was introduced as a long-term if not definitive solution for aortic pathology. However, the rate of reoperation is not negligible. METHODS: This single-center prospective study assessed the general outcome of Ross reoperation and patients' perceived quality of life compared with 2 control groups (Ross non-reoperation and mechanical aortic valve replacement). Patient's preference regarding the choice between mechanical aortic valve and Ross procedure was investigated in a subgroup that could theoretically have been directed to either of the 2 procedures. RESULTS: Between 2005 and 2017, 64 consecutive patients underwent reoperation after Ross. Median age was 31 years. Median freedom from reoperation after the Ross procedure was 136 months. An autograft reoperation was required in 49, and 25 had homograft failure. No in-hospital death was recorded. Mean follow-up was 77 months (range, 6-164 months). Quality of life was assessed with the 36-Item Short Form Health Survey questionnaire. The Ross reoperation group showed a lower score involving psychological concerns compared with the other groups. In the reoperated-on patients group, 52 had adequate aortic annulus dimensions to receive a prosthetic valve instead of a Ross procedure. When asked whether they would make the same choice, only 31% confirmed the preference. CONCLUSIONS: Reoperations after Ross procedure have low mortality and morbidity. Long-term follow-up showed a high quality of life, even after reoperations. However, owing to psychological concerns after the redo operation, when choosing a Ross procedure, it is our duty to thoroughly explain to patients that a high level of disillusion is predictable in case of reoperations.
