Background: The level of radiation exposure received by operators performing transcatheter aortic valve replacement (TAVR) is not well investigated. The aim of this study is to measure the amount of radiation received by operators performing transfemoral TAVR and to identify various patient and procedural characteristics associated with increased radiation exposure. Methods: Primary (operator 1) and secondary (operator 2) operators' equivalent radiation doses in micro Sieverts (µSv) were calculated prospectively using real-time radiation dosimeters for a total of 140 consecutive transfemoral TAVRs. Corresponding eye and thorax radiation exposures between the operators were compared. Associations between various patient and procedural characteristics and the radiation exposure were tested using the t-test and Wilcoxon Mann-Whitney rank-sum test with Monte Carlo estimation. Multivariable regression analysis was also conducted. Results: Operator 1 had significantly higher cumulative equivalent radiation exposure than operator 2 (86 µSv vs 38 µSv, p-value: <0.0001) which was consistent at the level of the thorax (67 µSv vs 22 µSv, p-value: <0.0001), but not at the level of the eye (16.5 µSv vs 15 µSv, p-value: 0.30). On multivariable analysis, patient obesity and intraprocedural complications were associated with higher radiation exposure to both operators. Ad hoc percutaneous coronary intervention led to excessive radiation exposure to the secondary operator. Conclusions: Transfemoral TAVR is associated with a modest amount of radiation exposure to operators and is significantly higher for the primary operator than for the secondary operator.
RESUMO
BACKGROUND: Aortic stenosis is prevalent among older adults and is commonly treated with transcatheter aortic valve replacement. Both high- and low-risk patients benefit from early mobility and discharge after this procedure; however, hospital protocols to improve patient mobility and shorten hospital stays have not been systematically implemented. OBJECTIVE: To develop and evaluate a post-transcatheter aortic valve replacement protocol to standardize care and efficiently advance patients from the operating room to discharge. METHODS: A prospective pre-post design was used to evaluate the effect of the new standardized protocol on length of stay, timing of mobility, time spent in intensive care, and quality of life in patients undergoing transcatheter aortic valve replacement between April 2019 and March 2020. INTERVENTIONS: Interventions included team-based education and integration of an evidence-based order set into the electronic health record. Education was provided to both patients and staff. RESULTS: At 6 months after implementation of the intervention, statistically significant improvements were observed in mean overall (5.26 vs 2.45 days; P = .001) and postprocedure (3.05 vs 2.16 days; P = .004) length of stay. No significant difference was found in performance on the 5-meter walk test. Quality of life improved in both groups from baseline to 30-day follow-up (P = .01). CONCLUSION: Implementation of the post-transcatheter aortic valve replacement protocol was associated with significant improvement in overall and postprocedure length of stay and improved quality of life. Additional work is needed to examine strategies to ensure safe next-day discharge.

A 49-year-old man presented to the emergency room after a cardiac arrest. On arrival, the patient's ECG showed ST-segment elevations in the aVR and anteroseptal leads with diffuse ST depression suggestive of left main coronary artery occlusion. Subsequent coronary catheterisation showed normal coronaries but revealed severe stenosis of his bicuspid aortic valve. A surgical replacement of the aortic valve was performed, and the patient recovered successfully.

The number of patients with advanced heart failure receiving left ventricular assist device (LVAD) implantation has increased dramatically over the last decade. There are limited data available about the nationwide trends of complications leading to readmissions after implantation of contemporary devices. Patients who underwent LVAD implantation from January 2013 to December 2013 were identified using International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) code 37.66 from the Healthcare Cost and Utilization Project's National Readmission Database. The top causes of unplanned 30-day readmission after LVAD implantation were determined. Survey logistic regression was used to analyze the significant predictors of readmission. In 2013, there were 2,235 patients with an LVAD implantation. Of them, 665 (29.7%) had at least 1 unplanned readmission within 30 days, out of which 289 (43.4%) occurred within 10 days after discharge. Implant complications (14.9%), congestive heart failure (11.7%), and gastrointestinal bleeding (8.4%) were the top 3 diagnoses for the first readmission and accounted for more than a third of all readmissions. Significant predictors of readmissions included a prolonged length of stay during the index admission, Medicare insurance, and discharge to short-term facility. In conclusion, despite increased experience with LVADs, unplanned readmissions within 30 days of implantation remain significantly high.

BACKGROUND: Mild and moderate functional ischemic mitral insufficiency present at the time of surgical revascularization present clinical uncertainty. It is unclear whether the relatively poor outcomes in this cohort are dependent on valvular function or related to left ventricular dysfunction. The purpose of this study was to examine the early and late outcomes in patients with less-than-severe functional ischemic mitral insufficiency at the time of isolated coronary artery bypass grafting (CABG). METHODS AND RESULTS: From 1996 through 2004, 2242 consecutive patients undergoing isolated CABG were identified as having none to moderate mitral regurgitation (MR) and no valve leaflet pathology. All of the patients at this single institution routinely had an intraoperative transesophageal echocardiography, prospectively quantified MR, and ejection fraction (EF). The New York State Cardiac Surgery Reporting System infrastructure was used to prospectively collect in-hospital patient variables and outcomes. Social Security Death Benefit Index was used to determine long-term survival. Odds ratio and significance (P value) are presented for each determined risk factor. There were 841 patients (37.5%) with no MR, 1137 (50.7%) with mild MR, and 264 (11.8%) with moderate MR. The patients with moderate MR were more likely to be older, female, and have more renal disease, previous MI, congestive heart failure, previous cardiac surgery, and lower EFs. Hospital mortality was independently and significantly associated with renal disease, decreasing EF, increasing age, previous cardiac operation, and cerebral vascular disease. Multivariable analysis revealed decreased survival with increasing age, previous operation, congestive heart failure, diabetes, nonelective operation, decreasing EF, and the presence of moderate MR (expbeta = 1.49; P=0.007) and mild MR (expbeta = 1.34; P=0.033). CONCLUSIONS: Independent of ventricular function, mild and moderate functional mitral insufficiency are associated with significantly decreased survival in patients undergoing CABG. Whether correction of moderate functional MR at the time of CABG improves outcome still needs to be determined.

A 23-year-old African American woman with a past medical history of systemic lupus erythematous (SLE), secondary hypertension, and end stage renal disease (ESRD) on hemodialysis for eight years was stable until she developed symptomatic severe mitral regurgitation with preserved ejection fraction. She underwent a bioprosthetic mitral valve replacement (MVR) at outside hospital. However, within a year of her surgery, she presented to our hospital with NYHA class IV symptoms. She was treated for heart failure but in view of her persistent symptoms and low EF was considered for heart and kidney transplant. This was a challenge in view of her history of lupus. We presumed that her stenosis of bioprosthetic valve was secondary to lupus and renal disease. We hypothesized that her low ejection fraction was secondary to mitral stenosis and potentially reversible. We performed a dobutamine stress echocardiogram, which revealed an improved ejection fraction to more than 50% and confirmed preserved inotropic contractile reserve of her myocardium. Based on this finding, she underwent a metallic mitral valve and tricuspid valve replacement. Following surgery, her symptoms completely resolved. This case highlights the pathophysiology of lupus causing stenosis of prosthetic valves and low ejection cardiomyopathy.
RESUMO
BACKGROUND: Folding plasty (FP) for posterior mitral leaflet repair (PLR) is a technique that reduces the height of the repaired leaflet, closes the gap created by leaflet resection by rotation of residual leaflet, and reduces the need for localized annular plication. This report reviews late outcomes with FP repair. METHODS: From January 1994 to August 2006, 1,402 mitral valve repairs were performed for degenerative disease: 1,012 had PLR and 531 had FP technique. RESULTS: Overall hospital mortality was 2.4% (33 of 1,402 patients) and 1.3% (14 of 1,103 patients) for isolated mitral repair. For those patients with PLR, mortality for all procedures was 1.5% (15 of 1,012 patients) and 1.2% (11 of 891 patients) for isolated PLR repairs. Mortality was 0.9% (5 of 531 patients) for FP. In the last 5 years FP was used in 64.4% of PLR, compared with 35.6% of PLR in the prior era (p < 0.001). The 10-year actuarial freedom from mitral reoperation was 89%; 10-year freedom from reoperation or recurrent severe mitral insufficiency was 86% with FP and 87% without (p = 0.76). The 5-year freedom from reoperation or recurrent severe insufficiency was 89% when an annuloplasty device was used and 62% when not used (p < 0.001). CONCLUSIONS: Repair of posterior leaflet prolapse with FP is straightforward and durable. In our experience, FP is currently used for two thirds of PLR. These data also confirm that valve repair for degenerative disease should include an annuloplasty device for optimal late results.

BACKGROUND: A recent report suggested that a thoracotomy approach for reoperative mitral valve (MV) procedures was associated with an equivalent mortality and an unacceptable risk of stroke. We assessed these outcomes in a single institution's experience. METHODS: From 1992 through 2007, 905 patients underwent reoperative MV procedures. The approach was a median sternotomy in 612 (67.6%), right anterior thoracotomy in 242 (26.7%), and left posterior thoracotomy in 51 (5.6%). Concomitant procedures in 411 patients (67.6%) included aortic procedures in 189, tricuspid procedures in 170, and coronary artery bypass grafting in 90. Hypothermic fibrillation was used in 65 patients. Logistic analysis was used to analyze risk factors and outcomes. RESULTS: Overall mortality was 12.7% (115 of 905), 6.7% (25 of 371) for first time isolated MV reoperations, and 10.1% (50 of 494) for all isolated MV operations. Overall incidence of stroke was 3.8% (34 of 905); 10.9% (9 of 82) with retrograde arterial perfusion and 3.0% (25 of 824) with central aortic cannulation (p < 0.001). For isolated MV reoperations, the incidence of stroke was 4.3% (21 of 494): 2.9% (7 of 241) for antegrade perfusion and 5.5% (14 of 253) for retrograde perfusion (p = 0.15). Risk factors for death were age (p < 0.001), renal failure (p < 0.01), tricuspid valve disease (p < 0.001), chronic obstructive pulmonary disease (odds ratio [OR], 2.9; 95% confidence interval [CI], 1.8 to 4.9; p < 0.001), emergency procedure (OR, 2.9; 95% CI, 1.2 to 6.9; p = 0.02), and ejection fraction less than 0.30 (OR, 1.9; 95% CI, 1.1 to 3.3, p = 0.018). Risk factors for stroke were retrograde perfusion (OR, 4.4; 95% CI, 1.8 to 10.3; p < 0.01) and ejection fraction below 0.30 (OR, 2.1; 95% CI, 0.9 to 5.0; p = 0.09). CONCLUSIONS: The incidence of stroke in reoperative MV operations is associated with perfusion strategies, not with the incisional approach. Reoperative sternotomy and minithoracotomy with central cannulation are both useful for reoperative MV procedures and are associated with low stroke rates.

BACKGROUND: Short-term results with minimally invasive approaches for mitral valve repair in degenerative disease have been encouraging, with potential for diminishing blood loss and hospital length of stay. Little is known, however, about the long-term efficacy of this approach. This report analyzes a single institution's results over 12 years with minimally invasive mitral repair. METHODS: Since 1986, 3,057 patients have undergone mitral valve repair; 1,601 patients had degenerative disease and are the subject of this report. Minimally invasive mitral repair was done in 1071 patients with a right anterior minithoracotomy and direct vision. Clinical and echocardiographic variables were entered prospectively into a database. RESULTS: Hospital mortality was 2.2% for all patients (36 of 1601); 1.3% for isolated minimally invasive (9 of 712) and 1.3% (3 of 223) for isolated sternotomy mitral valve repair; and 3.6% (24 of 666) for valve repair plus a concomitant cardiac procedure. For isolated valve repair, 8-year freedom from reoperation was 91% +/- 2% for sternotomy and 95% +/- 1% for minimally invasive (p = 0.24), and 8-year freedom from reoperation or severe recurrent insufficiency was 90% +/- 2% for sternotomy and 93% +/- 1% for minimally invasive (p = 0.30). Eight-year freedom from all valve-related complications was 86% +/- 3% for sternotomy and 90% +/- 2% for minimally invasive (p = 0.14). CONCLUSIONS: These data indicate that long-term outcomes after minimally invasive mitral repair are excellent and equivalent to results achieved with sternotomy. In view of previously published advantages of short-term morbidity, minimally invasive approaches to mitral valve surgery deserve expanded use.

BACKGROUND: Percutaneous aortic valve replacement (PAVR) trials are ongoing in patients with an elevated European System for Cardiac Operative Risk Evaluation (EuroSCOREs), patients believed to have high mortality rates and poor long-term prognoses with valve replacement surgery. It is, however, uncertain that the EuroSCORE model is well calibrated for such high-risk AVR patients. We evaluated EuroSCORE prediction vs a single institution's surgical results in this target population. METHODS: From January 1996 through March 2006, 731 patients with EuroSCOREs of 7 or higher underwent isolated AVR. In this cohort, 313 (42.8%) were septuagenarians, 322 (44.0%) were octogenarians or nonagenarians, 233 (31.9%) had had previous cardiac procedures, 237 (32.4%) had atheromatous aortas, and 127 (17.4%) had cerebrovascular disease. A minimally invasive approach was used in 469 (64.2%). Data collection was prospective. Long-term survival was computed from the Social Security Death Benefit Index. RESULTS: The mean EuroSCORE was 9.7 (median, 10), and the mean logistic EuroSCORE was 17.2%. Actual hospital mortality was 7.8% (57 of 731). Multivariate analysis showed ejection fraction of less than 0.30 (p = 0.002; odds ratio [OR], 3.13), chronic obstructive pulmonary disease (p = 0.019; OR, 2.14), and peripheral vascular disease (p = 0.048; OR, 2.13) were significant predictors of hospital mortality. Complication(s) occurred in 73 patients (9.9%). Freedom from all-cause death (including hospital mortality) was 72.4% at 5 years (n = 152). Age (p < 0.001), previous cardiac operations (p < 0.014; OR, 1.51), renal failure (p < 0.002; OR, 2.37), and chronic obstructive pulmonary disease (p < 0.007; OR, 1.30) were predictors of worse survival. CONCLUSIONS: Logistic EuroSCORE greatly overpredicts mortality in these patients. Five-year survival is good, unlike suggestions from earlier EuroSCORE analyses. This raises concern about unknown long-term percutaneous prosthesis function. Clinical trials for these patients must include randomized surgical controls and have long-term end points.

Chronic heart failure (CHF) has become an epidemic in the United States, with approximately 550,000 new cases annually. With the evolution of pharmacotherapy targeting neurohormonal pathways, the annual mortality in subjects with New York Heart Association (NYHA) class IV CHF has dramatically improved from 52% in the seminal CONSENSUS trial to less than 20% in more recent trials. Suppression of the renin-angiotensin-aldosterone system remains the first line of neurohormonal blockade followed by the addition of selective beta-adrenoreceptor blockers. For patients with NYHA class I and II symptoms, mortality rates have decreased to approximately 5% or less per year with the use of angiotensin-converting enzyme inhibitors, beta-blockers and aldosterone receptor blockers. However, after achieving optimal doses of the indicated pharmacotherapy, and despite the additional benefits obtained with biventricular pacemakers, there are still many patients who continue to experience signs and symptoms of CHF. Recognizing the beneficial effects of the above treatments on left ventricular (LV) remodeling, strategies have been developed to surgically reshape the left ventricle in patients with LV dilation who have associated poor LV function. This review will discuss the techniques and recent developments regarding surgical reshaping of the dilated, dysfunctional, and remodeled left ventricle.

OBJECTIVE: The purpose of this study was to examine the influence of caudal anesthesia on outcomes (pediatric intensive care unit [PICU] length of stay, hospital length of stay, ventilatory time, early extubation rate) in pediatric patients undergoing congenital heart disease repair requiring cardiopulmonary bypass (CPB). DESIGN: Retrospective. SETTING: University teaching hospital. PARTICIPANTS: Pediatric patients undergoing surgery to treat congenital heart disease between 1999 and 2002. INTERVENTION: None. MEASUREMENTS AND MAIN RESULTS: Thirty-four patients with atrial septal defect (ASD), 37 with ventricular septal defect, and 46 with tetralogy of Fallot (TOF) were included in the analysis. No differences were found in preoperative and intraoperative data between caudal and noncaudal group for each disorder. There was no difference between caudal and noncaudal groups in PICU and hospital stay. A statistically significant difference was found in the postoperative ventilatory time in patients with ASD and TOF between caudal and noncaudal groups. The early extubation rate was higher in the TOF caudal group compared with the noncaudal group. CONCLUSIONS: This retrospective study demonstrated that postinduction placement of caudal anesthesia does not affect PICU or hospital length of stay. A well-controlled prospective study is needed to confirm these findings.

To plan effective management of congenital heart disease, one needs the clearest understanding of the anatomy. Although echocardiography and angiography are the dominant imaging modalities in patients with congenital heart disease, magnetic resonance (MR) imaging and computed tomography (CT) are valuable noninvasive adjuncts. MR imaging and CT are effective in demonstrating the complex cardiovascular morphology present in congenital heart disease, especially the extracardiac morphology. In patients with tetralogy of Fallot with complex pulmonary artery anatomy, MR imaging and CT are useful in demonstrating the pulmonary artery anatomy, along with the significant aortopulmonary collateral vessels. In the heterotaxy syndromes, patients often have unusual atriovenous connections. MR imaging allows accurate identification of the hepatic, systemic, and pulmonary veins and their relationships to both atria. CT and MR are the imaging modalities of choice in a patient who is thought to have a vascular ring. Treatment of aortic coarctation is usually performed on the basis of typical clinical and echocardiographic findings. In patients with atypical clinical or echocardiographic findings, MR imaging and CT yield helpful information that can change the treatment plan. The enhanced preoperative understanding of congenital heart disease provided by MR imaging and CT simplifies surgical decision making and consequently may improve outcome.

Placement of a pacing lead into a branch of the coronary sinus for biventricular pacing sometimes is difficult or impossible. Surgical completion typically has included immediate or subsequent thoracotomy lead placement with hookup to the device at the time of chest surgery. We describe an alternative procedure of complete device-lead hookup and permanent pocket closure in the electrophysiology laboratory. The left ventricular lead is an epicardial type. The lead is tunneled to a position where the surgeon subsequently can recover it using the thoracotomy incision and implant the lead on the epicardium using device-based testing.
