RESUMO

Hutchinson-Gilford progeria syndrome is an autosomal dominant, rare, fatal pediatric segmental premature aging disease. Cardiovascular and cerebrovascular diseases constitute the major cause of morbidity and mortality. Patients with the syndrome and severe aortic valve stenosis have been described in the literature, and for all of them a strategy of conservative management has been followed. We describe the first successful treatment of a 23-year-old Hutchinson-Gilford progeria syndrome patient with severe aortic stenosis who underwent transapical transcatheter aortic valve replacement.

RESUMO

New-generation devices such as Evolut and Portico have provided favorable results in patients who underwent transcatheter aortic valve implantation (TAVI) for aortic stenosis, but their comparative effectiveness remains debated, despite its relevance when envisioning TAVI in low-risk patients. We evaluated the safety and efficacy of 2 leading TAVI devices (Evolut and Portico) used by the same team of experienced TAVI operators, focusing on long-term outcomes, including major adverse events (i.e., the composite of death, stroke, myocardial infarction, major vascular complication, or major bleeding). Unadjusted and propensity score-adjusted analyses were carried out. A total of 233 patients were included, 119 (51.1%) receiving Evolut and 114 (49%) Portico. Baseline and procedural data showed significant between-device differences, including functional class, surgical risk, chronic obstructive pulmonary disease, renal function, transesophageal guidance, device size, postdilation, and procedural time (all p <0.05). Yet, acute and in-hospital outcomes were not significantly different (all p >0.05). Follow-up status was ascertained in 228 (98%) patients after 15.0 ± 7.6 months. Unadjusted analysis showed similar rates of major adverse events, as well as the individual risk of death, stroke, myocardial infarction, major vascular complication, major bleeding, and pacemaker implantation (all p >0.05). Even at propensity score-adjusted analysis outcomes were not significantly different with Evolut and Portico (all p >0.05). In conclusion, Evolut and Portico devices yield similarly favorable results at long-term follow-up when used by experienced TAVI operators.

RESUMO

Thrombus-in-transit through a patent foramen ovale (PFO) in a patient with pulmonary embolism (PE) is a rare event with high mortality rates. We report the case a of 53-year-old woman admitted for dyspnea, cough, hemoptysis, presyncope, tachycardia, and hypotension. A recent fall down the stairs with costal trauma was also reported. At transthoracic echocardiography, dilated right atrium with the presence of a large floating thrombus was found, protruding into the left atrium through a PFO; lower extremity vascular ultrasound showed right great saphenous vein thrombosis extended over the saphenofemoral junction up to the common femoral vein. CT scan showed submassive thromboembolism; surgical thrombectomy was, therefore, performed with the closure of the PFO; an inferior vena cava filter was also positioned for the prevention of recurrent episodes of thromboembolism. The patient was discharged in therapy with apixaban 5 mg twice a day. Two-month follow up was uneventful. Large thrombi in transit through PFO can be found at transthoracic echocardiography. The management, either medical or surgical, should be aimed at preventing systemic thromboembolism.

RESUMO

OBJECTIVES: The most commonly used accesses for transcatheter aortic valve implantation (TAVI) are the transfemoral (TF-TAVI) and the transapical (TA-TAVI) ones. There are concerns about TA-TAVI use in patients with reduced left ventricular ejection fraction (LVEF). The aim of this retrospective multicentre study was to compare the outcomes of TA-TAVI and TF-TAVI in patients with poor LVEF. METHODS: Patients with LVEF ≤35% were included in the analysis. Data were obtained from the Italian Transcatheter Balloon-Expandable Registry (ITER), which enrolled patients undergoing TAVI with the Sapien bioprosthesis in 33 national centres. Patients were divided into 2 groups according to the access: TA or TF. A multivariable logistic regression analysis was performed in order to evaluate whether the type of approach (TA and TF) has an impact on outcomes. RESULTS: Between 2007 and 2012, 1882 patients were enrolled in the Registry. LVEF ≤35% was found in 208 (11.1%) patients. TA-TAVI and TF-TAVI were performed in 69 (33.2%) and 139 (66.8%) patients, respectively. Overall 30-day mortality was 11.6% and 7.9% in TA and TF patients, respectively (P = 0.45). Overall Kaplan-Meier survival was significantly higher in the TF-TAVI group (log rank: P = 0.003). Age [odds ratio (OR) 1.066, P = 0.016], creatinine (OR: 2.301, P < 0.001), preoperative permanent pacemaker (OR: 4.662, P = 0.035) and TA approach (OR: 2.577, P = 0.006) were identified as independent predictors of overall mortality at follow-up. However, the TA approach resulted an independent variable of mortality only 3 years after TAVI. CONCLUSIONS: TAVI yields good results in patients with depressed LVEF. Age, preoperative creatinine and preoperative pacemaker are independently associated with mortality. The TA access is associated with mortality only after 3 years of follow-up, thus probably reflecting a worse general clinical status of these patients.

RESUMO

Primary cardiac tumors are a rare entity whose incidence in the general population ranges from 0.0017% to 0.28%. Myxomas represent nearly half of all primary benign cardiac tumors and they prevalently affect female patients. Embolic manifestation is rare with a reported incidence of 0.06%.We present the case of a 30-year-old male patient with acute anterolateral infarction caused by total occlusion of the left anterior descending artery as a consequence of a left atrial myxoma embolization. Urgent surgical resection of the mass didn't avoid early recurrence of atrial myxoma, whose second presentation was again myocardial infarction.This case alerts physicians to "unusual" myocardial infarction patients, when atherosclerotic pathogenesis appears unlikely. In these cases early echocardiographic evaluation should be mandatory and atrial myxoma should be considered among the possible causes. Complete surgical resection is the only effective therapeutic option to improve prognosis; the chance of tumor recurrence should dictate careful research for additional myxomas during surgery and stricter follow-up planning.

RESUMO

Transcatheter aortic valve replacement (TAVR) in the presence of a mechanical mitral valve (MMV) prosthesis is challenging due to the stiff mitral cage in the boundaries of the aorto-mitral curtain. We describe the technique for TAVR using the ACURATE-neo™ aortic bioprosthesis in a patient with a MMV prosthesis.

RESUMO

Advanced chronic kidney disease (CKD) is associated with poor outcomes in patients who underwent surgical aortic valve replacement, whereas its prognostic role in transcatheter aortic valve implantation (TAVI) remains unclear. This study aimed to investigate outcomes in patients with advanced CKD who underwent TAVI. A total of 1,904 consecutive patients who underwent balloon-expandable TAVI in 33 centers between 2007 and 2012 were enrolled in the Italian Transcatheter Balloon-Expandable Valve Implantation Registry. Advanced CKD was defined according to the estimated glomerular filtration rate: 15 to 29 ml/min/1.73 m2 stage 4 (S4), <15 ml/min/1.73 m2 stage 5 (S5). Edwards Sapien or Sapien-XT prosthesis were used. The primary end point was all-cause mortality during follow-up. Secondary end points were major adverse cardiac events at 30 days and at follow-up, defined with Valve Academic Research Consortium 2 criteria. A total of 421 patients were staged S5 (n = 74) or S4 (n = 347). S5 patients were younger and had more frequently porcelain aorta and a lower incidence of previous stroke. Periprocedural and 30-day outcomes were similar in S5 and S4 patients. During 670 (±466) days of follow-up, S5 patients had higher mortality rates (69% vs 39%, p <0.01) and cardiac death (19% vs 9%, p = 0.02) compared with S4 patients. Male gender (hazard ratio [HR] 1.6, 95% confidence interval [CI] 1.2 to 2.2), left ventricular ejection fraction <30% (HR 2.3, 95% CI 1.3 to 4), atrial fibrillation (HR 1.4, 95% CI 1.0 to 1.9), and S5 CKD (HR 1.5, 95% CI 1.0 to 2.1) were independent predictors of death. In conclusion, TAVI in predialytic or dialytic patients (i.e., S5) is independently associated with poor outcomes with more than double risk of death compared with patients with S4 renal function. Conversely, in severe CKD (i.e., S4) a rigorous risk stratification is required to avoid the risk of futility risk.

RESUMO

OBJECTIVES: Evaluating the efficacy of 2 new percutaneous devices specifically designed to be placed through the right internal jugular vein, therefore named "necklines," for achieving retrograde cardioplegia and pulmonary venting in the setting of minimally invasive aortic valve replacement (MIAVR). DESIGN: Case series. SETTING: University-affiliated private hospital. PARTICIPANTS: Patients undergoing MIAVR. INTERVENTIONS: Necklines were placed by the anesthesiologist using transesophageal electrocardiography, with pressure guidance before the surgical procedure was initiated. MEASUREMENTS AND MAIN RESULTS: The records of 51 consecutive patients who underwent MIAVR with necklines placement were reviewed retrospectively. The access for MIAVR was through either a J-hemisternotomy or a right anterior thoracotomy. The efficacy of the 2 catheters, successful placement rate, time needed to deploy catheters, and perioperative complications were recorded. Necklines were placed successfully in all patients in 23±13 minutes. A total of 110 doses of retrograde cardioplegia were delivered at a mean flow rate of 173±35 mL/min and a mean pressure of 41±6 mmHg. The pulmonary catheter ensured venting of the heart that was graded by surgeons as "excellent" in 33 patients, "sufficient" in 12 patients, and "not adequate" in 2 patients. There were no major adverse events or deaths. CONCLUSIONS: Necklines ensure effective retrograde cardioplegia and venting of the heart, provide optimal surgical vision and access during MIAVR, and allow surgeons to operate in an unobstructed surgical field. Nevertheless, additional studies are required to determine whether the use of necklines is associated with better outcomes than those with conventional methods.

RESUMO

The Engager aortic bioprosthesis consists of bovine pericardial leaflets mounted on a self-expandable frame with unique anatomic orientation capabilities to engage the aortic valve cusps. We report the initial North American transcatheter aortic valve implantation (TAVI) experience with the Engager device. Transapical TAVI was performed in 4 patients (mean age 80 ± 6 years, Society of Thoracic Surgeons score 5 ± 1%). The valve was anatomically oriented and successfully implanted in all patients. There were no conversions to open operation or major procedure-related adverse events. Pacemaker implantation was necessary in 1 patient. None of the patients showed paravalvular leak. The Engager device for TAVI provides anatomic orientation and anchoring that prevents coronary obstruction and paravalvular leak.

RESUMO

OBJECTIVES: The aim of this multicentre study is to report the clinical experiences of all patients undergoing transcatheter aortic valve implantation (TAVI) with a balloon-expandable device in Italy. METHODS: The Italian Transcatheter balloon-Expandable valve Registry (ITER) is a real-world registry that includes patients who have undergone TAVI with the Sapien (Edwards Lifesciences, Irvine, CA, USA) bioprosthesis in Italy since it became available in clinical practice. From 2007 to 2012, 1904 patients were enrolled to undergo TAVI in 33 Italian centres. Outcomes were classified according to the updated Valve Academic Research Consortium (VARC-2) definitions. A multivariable analysis was performed to identify independent predictors of all-cause mortality. RESULTS: Mean age was 81.7 (SD:6.2) years, and 1147 (60.2%) patients were female. Mean Logistic EuroSCORE was 21.1% (SD:13.7). Transfemoral, transapical, transaortic and transaxillary TAVI was performed in 1252 (65.8%), 630 (33.1%), 18 (0.9%) and 4 (0.2%) patients, respectively. Operative mortality was 7.2% (137 patients). The VARC-2 outcomes were as follows: device success, 88.1%; disabling stroke, 1.0%; life-threatening and major bleeding 9.8 and 10.5%, respectively; major vascular complication, 9.7%; acute kidney injury, 8.2%; acute myocardial infarction ≤72 h, 1.5%. Perioperative pacemaker implantation was necessary in 116 (6.1%) patients. At discharge, the mean transprosthetic gradient was 10.7 (SD:4.5) mmHg. Incidence of postoperative mild, moderate or severe paravalvular leak was, respectively, 32.1, 5.0 and 0.4%. A total of 444/1767 (25.1%) deaths after hospital discharge were reported: of these, 168 (37.8%) were classified as cardiac death. Preoperative independent predictors of all-cause mortality were male gender (HR: 1.395; 95% CI:1.052-1.849); overweight, BMI 25-30 kg/m2 (HR: 0.775; 95% CI: 0.616-0.974); serum creatinine level (every 1 mg/dl increase; HR: 1.314; 95% CI:1.167-1.480); haemoglobin level (every 1 g/dl increase; HR: 0.905; 95% CI:0.833-0.984); critical preoperative state (HR: 2.282; 95% CI: 1.384-3.761); neurological dysfunction (HR: 1.552; 95% CI:1.060-2.272); atrial fibrillation (HR: 1.556; 95% CI:1.213-1.995); pacemaker rhythm (HR: 1.948; 95% CI:1.310-2.896); NYHA Class III or IV (HR: 1.800; 95% CI:1.205-2.689 or HR: 2.331; 95% CI:1.392-3.903, respectively). CONCLUSIONS: TAVI with a balloon-expandable device in the 'real world' shows good mid-term outcomes in terms of survival, technical success, valve-related adverse events and haemodynamic performance.

RESUMO

OBJECTIVES: Stroke incidence after transcatheter aortic valve implantation (TAVI) still represents a concern. This multicentre study aimed at investigating the hypothesis that CHADS2 and CHA2DS2-VASc scores may be used to predict perioperative stroke after TAVI. METHODS: The Italian Transcatheter Balloon-Expandable Valve Implantation Registry (ITER) is a multicentre, prospective registry of patients undergoing balloon-expandable TAVI using Edwards Sapien and Sapien XT prosthesis between 2007 and 2012. The primary end-point of this study was the 30-day stroke rate. Secondary safety end-points were all the major adverse events based on Valve Academic Research Consortium (VARC-2) criteria. RESULTS: One thousand nine hundred and four patients were enrolled in the registry. Mean age was 81.6 ± 6.2 years and 1147 (60.2%) patients were female; mean CHADS2 and CHA2DS2-VASc scores were 2.2 ± 0.8 and 4.4 ± 1.1, respectively. Fifty-four (2.8%) patients had a stroke within 30 days. At multivariable logistic regression analysis, CHA2DS2-VASc (OR: 1.35, 95% CI: 1.03-1.78; P = 0.031) and previous cardiac surgery (OR: 1.96, 95% CI: 1.06-3.6; P = 0.033) but not CHADS2 (OR: 1.05, 95% CI: 0.76-1.44; P = 0.77) were found to be independent predictors of in-hospital stroke. A CHA2DS2-VASc score ≥5 was strongly related to the occurrence of in-hospital stroke (OR: 2.51, 95% CI: 1.38-4.57; P= 0.001). However, CHA2DS2-VASc score showed only poor accuracy for in-hospital stroke with a trend for better accuracy when compared with CHADS2 score (area under the curve: 0.61, 95% CI: 0.59-0.63 vs 0.51; 95% CI: 0.49-0.54, respectively, P = 0.092). CONCLUSIONS: In TAVI patients, CHA2DS2-VASc provided a strong correlation for in-hospital stroke but with low accuracy. Dedicated scores to properly tailor procedures and preventive strategies are needed.

RESUMO

A 67-year-old patient with rheumatic heart valve disease had undergone two cardiac surgeries at the age of 30 years, then re-do with mitral valve replacement at 50 years. She presented with congestive heart failure and hemolytic anemia. Doppler echocardiography showed moderate-severe mitral regurgitation due to paravalvular mitral valve leak (PVML) and severe pulmonary hypertension. Transesophageal echocardiography demonstrated severe PVML secondary to a large 20 mm-long PVML defect. Due to comorbidities, the heart team deemed a third reoperation at very high surgical risk; therefore, the patient was considered most suitable for a transcatheter approach to PVML closure. Two Occlutech paravalvular leak devices were successfully delivered using a simultaneous double-transapical access with double-wire technique.

RESUMO

OBJECTIVES: To evaluate the results of aortic valve replacement through sternotomic approach in redo scenarios (RAVR) vs transapical transcatheter aortic valve replacement (TAVR), in patients in the eighth decade of life or older already undergone previous coronary artery bypass grafting (CABG). METHODS: One hundred and twenty-six patients undergoing RAVR were compared with 113 patients undergoing TaTAVR in terms of 30-day mortality and Valve Academic Research Consortium-2 outcomes. The two groups were also analysed after propensity-matching. RESULTS: TaTAVR patients demonstrated a higher incidence of 30-day mortality (P = 0.03), stroke (P = 0.04), major bleeding (P = 0.03), worse 'early safety' (P = 0.04) and lower permanent pacemaker implantation (P = 0.03). TaTAVR had higher follow-up hazard in all-cause mortality [hazard ratio (HR) 3.15, 95% confidence interval (CI) 1.28-6.62; P < 0.01] and cardiovascular mortality (HR 1.66, 95% CI 1.02-4.88; P = 0.04). Propensity-matched patients showed comparable 30-day outcome in terms of survival, major morbidity and early safety, with only a lower incidence of transfusions after TaTAVR (10.7% vs RAVR: 57.1%; P < 0.01). A trend towards lower Acute Kidney Injury Network Classification 2/3 (3.6% vs RAVR 21.4%; P = 0.05) and towards a lower freedom from all-cause mortality at follow-up (TaTAVR: 44.3 ± 21.3% vs RAVR: 86.6 ± 9.3%; P = .08) was demonstrated after TaTAVR, although cardiovascular mortality was comparable (TaTAVR: 86.5 ± 9.7% vs RAVR: 95.2 ± 4.6%; P = 0.52). Follow-up freedom from stroke, acute heart failure, reintervention on AVR and thrombo-embolisms were comparable (P = NS). EuroSCORE II (P = 0.02), perioperative stroke (P = 0.01) and length of hospitalization (P = 0.02) were the determinants of all-cause mortality at follow-up, whereas perioperative stroke (P = 0.03) and length of hospitalization (P = 0.04) impacted cardiovascular mortality at follow-up. CONCLUSIONS: Reported differences in mortality and morbidity after TaTAVR and RAVR reflect differences in baseline risk profiles. Given the lower trend for renal complications, patients at higher perioperative renal risk might be better served by TaTAVR.

RESUMO

OBJECTIVE: Transcatheter aortic valve implantation (TAVI) and sutureless aortic valve replacement (SU-AVR) are suitable alternatives to conventional surgery. The aim of this study is to compare early outcomes of patients undergoing TAVI and SU-AVR. METHODS: Data were analyzed on patients who underwent TAVI and patients who underwent SU-AVR. Two matched cohorts (TAVI vs SU-AVR) were created using propensity scores; all analyses were repeated for transapical TAVI and transfemoral TAVI, separately. Outcomes were defined according to Valve Academic Research Consortium-2 criteria. RESULTS: A total of 2177 patients were included in the analysis: 1885 (86.6%) treated with TAVI; 292 (13.4%) treated with SU-AVR. Mortality in unmatched TAVI and SU-AVR patients was 7.1% and 2.1%, respectively, at 30 days, and 12.9% and 4.6%, respectively, at 1 year. No differences were found in 30-day mortality in the 214 matched patient pairs (3.7% vs 2.3%; P = .4), but patients treated with TAVI showed a lower incidence of device success (85.9% vs 98.6%; P < .001) and pacemaker implantation (2.8% vs 9.4%; P = .005), and a higher incidence of any paravalvular leakage (PVL). CONCLUSIONS: SU-AVR is associated with better device success and a lower incidence of PVL, compared with TAVI. Nevertheless, patients treated with SU-AVR were more likely to receive a permanent pacemaker. SU-AVR and TAVI provide good results in patients who have severe symptomatic aortic valve stenosis. Given the multiple therapeutic options available, patients may receive the treatment that is most appropriate for their clinical and anatomical characteristics.

RESUMO

We report the first known cases of successful implantation of the Edwards INTUITY (Edwards Lifesciences LLC, Irvine, CA) rapid-deployment valve in 3 patients with aortic stenosis presenting under emergency cardiogenic shock. At the 6-month follow-up, the 3 patients showed improved left ventricular function and improved functional capacity.

RESUMO

BACKGROUND: Anemia is a risk factor for adverse events after cardiac operations. We evaluated the incremental value of preoperative anemia over the European System for Cardiac Operative Risk Evaluation (EuroSCORE) II to predict hospital death after cardiac operations. METHODS: Data for 4,594 consecutive adults (1,548 women [33.7%]), aged 67 ± 11 years, who underwent cardiac operations from January 2011 to July 2013 were extracted from the Regional Cardiac Surgery Registry of Puglia. The last preoperative hemoglobin value was used, according to World Health Organization criteria, to classify anemia as mild (hemoglobin 11.0 to 12.9 g/dL in men and 11.0 to 11.9 g/dL in women) in 1,021 patients (22.2%) and as moderate to severe (hemoglobin <11.0 g/dL) in 593 patients (12.9%). The EuroSCORE II was used to evaluate predicted hospital death after operations. Logistic regression analysis for in-hospital death was performed including EuroSCORE II risk factors and anemia, with model discrimination quantified by C statistic and risk classification by the use of net reclassification improvement (NRI). RESULTS: Overall expected and observed mortality rates were 4.4% and 5.9%. Anemia was significantly associated with a mortality rate of 3.4% in patients without anemia, 7.7% in mild anemia, and 15.7% in moderate to severe anemia (p < 0.001) and also at multivariate analysis correcting for EuroSCORE II (p < 0.001). When anemia was analyzed with EuroSCORE II, the model improved in discrimination (C statistic = 0.852 vs 0.860; p = 0.007) and reclassification (category free-NRI, 0.592; p < 0.001), preserving the calibration with good concordance between predicted probabilities and outcome. CONCLUSIONS: Preoperative anemia has strong association with operative death in cardiac surgical patients. Anemia provides significant incremental value over the EuroSCORE II and should be considered for assessment of cardiac surgical risk.

RESUMO

OBJECTIVES: Patient selection is crucial to achieve good outcomes and to avoid futile procedures in patients undergoing transcatheter aortic valve replacement. The aim of this multicenter retrospective study was to identify independent predictors of 1-year mortality in patients surviving after transapical transcatheter aortic valve replacement. METHODS: We analyzed data from the Italian registry of transapical transcatheter aortic valve replacement that includes patients undergoing operation in 21 centers from 2007 to 2012. Futility was defined as mortality within 1 year after transapical transcatheter aortic valve replacement in patients surviving at 30 days. Thirty-day survivors were divided in 2 groups: futility (group F) and nonfutility (group NF). Cox proportional hazard regression analysis was performed to identify independent predictors of futility. RESULTS: We analyzed data from 645 patients with survival of 30 days or more after transapical transcatheter aortic valve replacement. Groups F and NF included 60 patients (10.8%) and 585 patients (89.2%), respectively. Patients in group F were more likely to have insulin-dependent diabetes (15% vs 7.2%, P = .03), creatinine 2.0 mg/dL or greater or dialysis (18.3% vs 8.2%, P = .01), logistic European System for Cardiac Operative Risk Evaluation greater than 20% (66.7% vs 50.3%, P = .02), preoperative rhythm disorders (40% vs 25.3%, P = .03), critical preoperative state (8.3% vs 1.8%, P = .002), and left ventricular ejection fraction less than 30% (15% vs 2.9%, P < .001). The multivariate analysis identified the following as independent predictors of futility: insulin-dependent diabetes (odds ratio, 3.1; P = .003), creatinine 2.0 mg/dL or greater or dialysis (odds ratio, 2.52; P = .012), preoperative rhythm disorders (odds ratio, 1.88; P = .04), and left ventricular ejection fraction less than 30% (odds ratio, 4.34; P = .001). CONCLUSIONS: According to our data, among patients undergoing transapical transcatheter aortic valve replacement, those with insulin-dependent diabetes, advanced chronic kidney disease, rhythm disorders, and low left ventricular ejection fraction have a higher risk to undergo futile procedures.

RESUMO

AIMS: To evaluate the feasibility of a cardiac surgery registry and to describe patients' characteristics, type of procedures performed, incidence of postoperative complications with short and middle-term mortality. METHODS: A database with clinical information and details on cardiac surgical operations was implemented by Puglia Health Regional Agency to collect data of each cardiac surgery procedure performed in the seven adult cardiac surgery centres of the region. Health regional agency personnel guaranteed data accuracy and quality control procedures. Mortality after the discharge was evaluated for residents in Puglia by linking clinical data to the Health Information System. RESULTS: From January 2011 to December 2012, 6429 operations were performed. All operations were included in the registry with very high completeness of collected data (95.3% per patient). The majority of the operations performed were coronary artery bypass graft alone (41.1%), valve surgery alone (26.2%), coronary artery bypass graft and valve surgery (11.4%), or valve with other surgery (11.8%). During a median follow-up of 12 months (interquartile range 6-18 months), 211 deaths were detected after the discharge. Overall, cumulative mortality from the operation was 8.2% at 6 months and 9.5% at 12 months. CONCLUSION: Implementation of a regional clinical registry of cardiac surgery is feasible with a great level of accuracy and the evaluation of mid-term mortality overcomes the limited value of hospital mortality. An accurate cardiac surgery registry elicits epidemiologic evaluations, comparisons between expected and observed mortality, incidence of postoperative complications and encourages a reliable public reporting.
