Triple valve surgery: results from a multicenter experience.

AIMS: Triple valve surgery (TVS) may still be considered a challenge in cardiac surgery, and is still associated with a not negligible mortality and morbidity. This study analyzed retrospectively patients' data from RERIC (Registro Regionale degli Interventi Cardiochirurgici) registry, to evaluate early and mid-term results of TVS. METHODS: From April 2002 to December 2013, data from n = 44 211 cardiac surgical procedures were collected from six Cardiac Surgery Departments (RERIC). Two hundred and eighty patients undergoing TVS were identified, including aortic and mitral replacement with tricuspid repair in 211 patients (75.3%), aortic replacement with mitral and tricuspid repair in 64 (22.9%) and triple valve replacement in 5 (1.8%). Univariate and multivariate analyses were performed to identify predictors of overall mortality or adverse outcomes. RESULTS: The mean age of the patients was 67.5 ±â€Š12.2. Overall in-hospital mortality rate was 7.9%: in-hospital mortality was 10.9% in mitral valve repair and 6.6% in mitral valve replacement, respectively. Tricuspid valve replacement was associated with the highest mortality rate (40%). Independent predictors of in-hospital mortality were serum creatinine greater than 2 mg/dl [odds ratio (OR) 4.5; P = 0.03], concomitant coronary artery bypass graft (CABG) (OR 3.8; P = 0.01) and previous cardiac surgery (OR 5.1; P = 0.04). Overall cumulative mortality rate at 1, 3 and 5 years was 14.7, 24.1 and 28.9%, respectively. Mitral valve replacement associated with tricuspid valve repair showed better survival rate (hazard ratio 0.1; P = 0.007). CONCLUSION: TVS has demonstrated satisfactory results in terms of in-hospital and mid-term mortality rate. Renal failure, reoperations and concomitant CABG resulted as risk factors for mortality; moreover, we could not demonstrate a mid-term better survival rate of mitral valve repair compared with the replacement.

Outcomes of patients undergoing concomitant mitral and aortic valve surgery: results from an Italian regional cardiac surgery registry.

OBJECTIVES: There are limited reliable data on the long-term survival of patients operated upon with double-valve surgery (DVS) in the literature. In this study, in-hospital mortality and 5-year survival were determined and the potential risk factors for increased mortality were identified and discussed. METHODS: This is a report of an observational retrospective study of 1167 patients undergoing concomitant aortic and mitral valve surgery from 2002 to 2011. Data were prospectively collected in a regional database from Emilia-Romagna (Italy). RESULTS: The overall in-hospital mortality rate for DVS was 6.9%. Both in-hospital and 1-year mortality were statistically significant between age groups. In-hospital mortality was significantly higher for patients with a smaller body mass index (BMI), for those who had concomitant coronary artery bypass grafting (CABG) and those who received mitral valve replacement (MVR) instead of plasty (MVP). In-hospital and 1-year mortality were highest in patients ≥70 who had implantation of mitral and aortic mechanical valves. There were significant differences in 5-year follow-up survival according to age, BMI and concomitant CABG. The choice of MVR and MVP did not affect 5-year survival. Multivariable analysis showed that patient-related factors appear to be the major determinant of late survival, irrespective of the type of operation or other intraoperative variables. CONCLUSIONS: Advanced age, smaller BMI and concomitant CABG are significant risk factors for mortality in DVS. MVP provided comparable 5-year outcomes with MVR. Multivariable analysis demonstrates that preoperative and clinical patient-related factors are the real burden in the successful treatment of patients undergoing double-valve procedures.

Acute aortic dissection: epidemiology and outcomes.

BACKGROUND: Little epidemiological information on acute aortic dissection (AAD) is available in the literature. The objective of the present study was to determine the incidence and mortality rates of AAD in the general population and to analyze its clinical features. METHODS: Data from the Emilia-Romagna regional database of hospital admissions was analyzed. Urgent admissions with the diagnosis of dissection of the aorta, dissection of the thoracic aorta and dissection of the thoracoabdominal aorta were selected. RESULTS: Between January 2000 and December 2008, 1499 Emilia-Romagna residents were hospitalized with a diagnosis of AAD. The patients were divided into three groups: Group A, 617 patients (41.2%) surgically treated for type A AAD; Group B, 93 complicated patients (6.2%) with type B AAD treated by endovascular stent-grafting and Group C, 789 patients (52.6%) suffering from any type of AAD medically treated. The overall annual incidence rate was 4.7%/100,000 people and was higher for men than for women (6.7% vs 2.9%).Two hundred ninety-six patients (19.8%) were 80 years of age or older.The overall in-hospital mortality rate was 27.7%, with mortality rates of 21.1%, 26.9% and 33% in Groups A, B and C, respectively. CONCLUSION: The incidence of AAD is not negligible and a notable rate of patients is ultra-octogenarian. A large number of patients with AAD had no surgery or interventional treatment. The results of surgical treatment for patients with type A dissection are acceptable but the results obtained in patients with complicated type B dissection who were treated with an endoprosthesis are dismal.

Aortic valve replacement: results and predictors of mortality from a contemporary series of 2256 patients.

OBJECTIVE: The study's objectives were to evaluate results and identify predictors of hospital and mid-term mortality after primary isolated aortic valve replacement; compare early and mid-term survival of patients aged more than 80 years or less than 80 years; and assess the effectiveness of the logistic European System for Cardiac Operative Risk Evaluation in predicting the risk for hospital mortality in octogenarians with a logistic European System for Cardiac Operative Risk Evaluation greater than 15% who are undergoing aortic valve replacement. METHODS: Data from 2256 patients undergoing primary isolated aortic valve replacement between January 2003 and December 2007 were prospectively collected in a Regional Registry (Regione Emilia Romagna Interventi Cardiochirurgia) and analyzed to estimate hospital and mid-term results. RESULTS: Overall hospital mortality was 2.2%. By multivariate analysis, New York Heart Association III and IV, Canadian Cardiovascular Society III and IV, pulmonary artery pressure greater than 60 mm Hg, dialysis, central neurologic dysfunction, and severe chronic obstructive pulmonary disease emerged as independent predictors of hospital mortality. At 3 years, the survival was 89.3%. The same predictors of hospital mortality plus ejection fraction of 30% to 50% and age more than 80 years emerged as independent risk factors for 3-year mortality. Compared with younger patients, octogenarians had a higher hospital mortality rate (3.72% vs 1.81%; P = .0143) and a reduced 3-year survival (82.3% vs 91.3%; P < .001). Three-year survival of octogenarians was comparable to the expected survival of an age- and gender-matched regional population (P = .157). The observed mortality rate in octogenarians with a logistic European System for Cardiac Operative Risk Evaluation greater than 15% (mean: 22.4%) was 7% (P < .001). CONCLUSIONS: This study provides contemporary data on the characteristics and outcome of patients undergoing first-time isolated aortic valve replacement.
