RESUMEN

OBJECTIVE: To determine the outcomes and eventual career paths for unmatched applicants by evaluating a historical cohort of unmatched applicants in the Urology Match. METHODS: The 2008-2014 AUA Match lists were obtained from the Society of Academic Urologists and 730 unique applicants were identified with at least one unmatched result. Additional information such as preliminary training and eventual specialty choice were obtained from publicly available sources. Comparative analysis with univariable and multivariable analysis was performed between eventual urologists and those who chose alternative career paths. RESULTS: Overall, 43.5% (318/730) of unmatched urology applicants subsequently continued their interest in Urology and 77.4% (246/317) of initially unsuccessful applicants eventually became urologists. Males (80.9%, P = .01), Doctor of Osteopathy (DO) degree (62.5%, P = <.001), and those undergoing a research year compared to a preliminary surgery year (85.2% vs 72.0% respectively, P = .047) had an increased likelihood of successfully becoming a urologist. The most common alternative specialty choices were Internal Medicine (13.8%), General Surgery (12.9%) and Anesthesiology (11.9%). CONCLUSION: Urology is a competitive surgical sub-specialty. Surprisingly, approximately 3 in 4 unmatched urology applicants who continue their interest in urology will eventually obtain a residency position. However, only 33.7% of initially unmatched students ultimately became urologists. Unmatched applicants have several viable pathways to obtain a urological residency position. Male gender, a DO degree, and a research year are associated with successfully obtaining a urology residency position.

RESUMEN

OBJECTIVES: We sought to develop strategies for management of the aortic arch in patients with Loeys-Dietz syndrome (LDS) through a review of our clinical experience with these patients and a comparison with our experience in patients with Marfan syndrome (MFS). METHODS: We reviewed hospital and follow-up records of 79 patients with LDS and compared them with 256 patients with MFS who served as reference controls. RESULTS: In the LDS group, 16% of patients presented initially with acute aortic dissection (AAD) (67% type A, 33% type B) or developed AAD during follow-up, compared with 10% of patients with MFS (95% type A, 5% type B). There was no difference between patients with LDS or MFS in need for subsequent arch interventions after aortic root surgery (46% vs 50%, P = 1.0). Among the patients who never had AAD, the need for arch repair at initial root surgery was greater in patients with LDS (5% vs 0.4%, P = .04), as was the need for any subsequent aortic surgery (12% vs 1.3%, P = .0004). Late mortality in patients with LDS after arch repair was greater than in those patients who had no arch intervention (33% vs 6%, P = .007). CONCLUSIONS: In the absence of dissection, patients with LDS have a greater rate of arch intervention after root surgery than patients with MFS. After a dissection, arch reintervention rates are similar in the 2 groups. Arch intervention portends greater late mortality in LDS.

RESUMEN

OBJECTIVE: Valve-sparing root replacement is an attractive alternative to composite mechanical or biologic prostheses for aortic root aneurysms in children. Data on outcomes in pediatric patients are limited. We present our institutional experience with 100 consecutive pediatric valve-sparing aortic root procedures. METHODS: All children who underwent valve-sparing root replacement at our institution from May 1997 to August 2017 were identified, and echocardiographic and clinical data were reviewed. The primary end point was mortality, and secondary end points included complications, further interventions, and subsequent valvular dysfunction. RESULTS: Median age at operation was 13.6 years (interquartile range, 9.42-15.9); 51 patients (51%) had Marfan syndrome, and 39 patients (39%) had Loeys-Dietz syndrome. Mean preoperative maximum sinus diameter was 4.4 ± 0.71 cm (z score 7.3 [5.7-9.3]). Most patients (n = 80, 80%) underwent reimplantation procedures with a Valsalva graft. Four patients (4%) underwent David I reimplantation with a straight-tube graft, 13 patients (13%) underwent a Yacoub remodeling procedure, and 3 patients (3%) underwent a Florida sleeve procedure. Perioperative valve-sparing root replacement mortality was 2% (n = 2). Six patients required late reintervention for development of pseudoaneurysms. Eight patients underwent additional aortic surgery. Average time to reoperation was 7.23 ± 4.56 years. Of the 84 patients undergoing a reimplantation procedure, 5 (5.9%) underwent late valve replacement versus 5 (33.3%) of the 15 patients who received a remodeling procedure (P = .001). CONCLUSIONS: Valve-sparing root replacement is a safe and effective option for children with aortic root aneurysms in children. The reimplantation procedure is preferred. Late aortic insufficiency and pseudoaneurysm formation remain late concerns.

RESUMEN

BACKGROUND: We compared quality outcomes between transperitoneal (TRPN) and retroperitoneal robotic partial nephrectomy (RRPN). METHODS: Two-center retrospective analysis of TRPN and RRPN from 10/2009 to 10/2015. Perioperative/renal function outcomes were analyzed. Primary endpoint was Pentafecta, a composite measure of quality [negative margin, no 30-day complication, ischemia time ≤25 min, return of glomerular filtration rate (eGFR) to >90% from baseline at last follow-up, and no chronic kidney disease upstaging]. Multivariable analysis (MVA) for factors associated with lack of optimal outcome was performed. RESULTS: 404 patients (TRPN 263, RRPN 141) were analyzed. Comparing TRPN vs. RRPN, mean tumor size (3.1 vs. 2.9 cm, p = 0.122) and RENAL score (7.4 vs. 7.2, p = 0.503) were similar. Most TRPN were anterior (65.0%) and most RRPN posterior (65.3%, p < 0.001). Operative time (p = 0.001) was less for RRPN. No significant differences between TRPN vs. RRPN were noted for ischemia time (23.1 vs. 22.8 min, p = 0.313), blood loss (p = 0.772), positive margins (p = 0.590), complications (p = 0.537), length of stay (p = 0.296), ΔeGFR (p = 0.246), eGFR recovery to >90% (55.9 vs. 57.4%, p = 0.833), and lack of CKD upstaging (84.0 vs. 87.2%, p = 0.464). Pentafecta rates were not significantly different (TRPN 33.9 vs. RRPN 43.3%, p = 0.526). MVA revealed increasing RENAL score (OR 1.5, p < 0.001) and decreasing baseline eGFR (OR 2.4, p = 0.017) as predictive for lack of Pentafecta. CONCLUSIONS: TRPN and RRPN have similar quality outcomes, though RRPN may offer modest benefit for operative time and have utility in posterior tumors. Association of increasing RENAL score and decreased baseline eGFR with lack of Pentafecta suggests dominant role of non-modifiable factors.

RESUMEN

BACKGROUND: Loeys-Dietz syndrome (LDS) is an aggressive aortopathy with a proclivity for aortic aneurysm rupture and dissection at smaller diameters than other connective tissue disorders. We reviewed our surgical experience of children with LDS to validate our guidelines for prophylactic aortic root replacement (ARR). METHODS: We reviewed all children (younger than 18 years) with a diagnosis of LDS who underwent ARR at our institution. The primary endpoint was mortality, and secondary endpoints included complications and the need for further interventions. RESULTS: Thirty-four children with LDS underwent ARR. Mean age at operation was 10 years, and 15 (44%) were female. Mean preoperative root diameter was 4 cm. Three children (9%) had composite ARR with a mechanical prosthesis, and 31 (91%) underwent valve-sparing ARR. Concomitant procedures included arch replacement in 2 (6%), aortic valve repair in 1 (3%), and patent foramen ovale closure in 16 (47%). There was no operative mortality. Two children (6%) required late replacement of the ascending aorta, 5 (15%) required arch replacement, 1 (3%) required mitral valve replacement, and 2 (6%) had coronary button aneurysms/pseudoaneurysms requiring repair. Three children required redo valve-sparing ARR after a Florida sleeve procedure, and 2 had progressive aortic insufficiency requiring aortic valve replacement after a valve-sparing procedure. There were 2 late deaths (6%). CONCLUSIONS: These data confirm the aggressive aortopathy of LDS. Valve-sparing ARR should be performed when feasible to avoid the risks of prostheses. Serial imaging of the arterial tree is critical, given the rate of subsequent intervention.

RESUMEN

Missile embolus to the heart, although uncommon, is one of the most challenging scenarios in trauma. We describe a 36-year-old man who presented with a gunshot wound to the left chest and a chest x-ray revealing a foreign body in the mediastinum. A median sternotomy was performed and an injury to the left ventricle was identified. After intraoperative echocardiography and fluoroscopy confirmed a foreign body in the aortic root, cardiopulmonary bypass was implemented. A bullet was retrieved from the noncoronary sinus of the aortic valve. Injuries to the anterior leaflet of the mitral valve and left ventricle were repaired.

RESUMEN

OBJECTIVES: Early experience with Loeys-Dietz syndrome (LDS) suggested an aggressive aortopathy with high risk of aneurysm dissection and rupture at young ages and at smaller aortic diameters than in other connective tissue disorders. We reviewed our experience with LDS to re-examine our indications and outcomes of surgical management. METHODS: We reviewed all patients with a diagnosis of LDS who underwent cardiovascular surgery at our institution. The primary endpoint was mortality, and secondary endpoints included postoperative complications and need for reintervention. RESULTS: Seventy-nine operated patients with LDS were identified. Mean age at first operation was 25 years, 39 (49%) were female, and 38 (48%) were children (age <18 years). Six (8%) patients presented with acute dissection. Five (6%) patients had a bicuspid aortic valve, and all presented with an ascending aortic aneurysm with a mean root diameter of 3.5cm. Twenty (25%) patients had a previous sternotomy. Sixty-five (82%) patients underwent aortic root replacement, of whom 52 underwent a valve-sparing operation and 4 had concomitant arch replacement. Mean aortic root diameter in this group was 4.2 cm. Nine (11%) patients underwent aortic arch replacement, 2 (3%) had isolated ascending aorta replacement, and 3 (4%) underwent open thoracoabdominal repair. There were 2 (3%) operative and 8 late deaths. Nineteen patients underwent subsequent operations for late aneurysm and/or dissection. Mean follow-up was 6 years (range 0-24 years). Kaplan-Meier survival was 88% at 10 years. CONCLUSIONS: Growing experience with LDS has confirmed early impressions of its aggressive nature and proclivity toward aortic catastrophe. Surgical outcomes are favorable, but reintervention rates are high. Meticulous follow-up with cardiovascular surveillance imaging remain important for management, particularly as clinical LDS subtypes are characterized and more tailored treatment is developed.

RESUMEN

OBJECTIVES: Prophylactic aortic root replacement improves survival in patients with Marfan syndrome with aortic root aneurysms, but the optimal procedure remains undefined. METHODS: Adult patients with Marfan syndrome who had Bentall or aortic valve-sparing root replacement (VSRR) procedures between 1997 and 2013 were identified. Comprehensive follow-up information was obtained from hospital charts and telephone contact. RESULTS: One hundred sixty-five adult patients with Marfan syndrome (aged > 20 years) had either VSRR (n = 98; 69 reimplantation, 29 remodeling) or Bentall (n = 67) procedures. Patients undergoing Bentall procedure were older (median, 37 vs 36 years; P = .03), had larger median preoperative sinus diameter (5.5 cm vs 5.0 cm; P = .003), more aortic dissections (25.4% vs 4.1%; P < .001), higher incidence of moderate or severe aortic insufficiency (49.3% vs 14.4%; P < .001) and more urgent or emergent operations (24.6% vs 3.3%; P < .001). There were no hospital deaths and 9 late deaths in more than 17 years of follow-up (median, 7.8 deaths). Ten-year survival was 90.5% in patients undergoing Bentall procedure and 96.3% in patients undergoing VSRR (P = .10). Multivariable analysis revealed that VSRR was associated with fewer thromboembolic or hemorrhagic events (hazard ratio, 0.16; 95% confidence interval, 0.03-0.85; P = .03). There was no independent difference in long-term survival, freedom from reoperation, or freedom from endocarditis between the 2 procedures. CONCLUSIONS: After prophylactic root replacement in patients with Marfan syndrome, patients undergoing Bentall and valve-sparing procedures have similar late survival, freedom from root reoperation, and freedom from endocarditis. However, valve-sparing procedures result in significantly fewer thromboembolic and hemorrhagic events.

RESUMEN

PURPOSE: To develop a preoperative prediction model using a computer-assisted volumetric assessment of potential spared parenchyma to estimate the probability of chronic kidney disease (CKD, estimated glomerular filtration rate [eGFR] <60 mL/min/1.73 m(2)) 6 months from extirpative renal surgery (nephron-sparing surgery [NSS] or radical nephrectomy [RN]). PATIENTS AND METHODS: Retrospective analysis of patients who underwent NSS or RN at our institution from January 2000 to June 2013 with a compatible CT scan 6-month renal function follow-up was performed. Primary outcome was defined as the accuracy of 6-month postoperative eGFR compared with actual postoperative eGFR based on root mean square error (RMSE). Models were constructed using renal volumes and externally validated. A clinical tool was developed on the best model after a given surgical procedure using area under the curve (AUC). RESULTS: We identified 130 (51 radical, 79 partial) patients with a median age of 58 years (interquartile range [IQR] 48-67) and preoperative eGFR of 82.1 (IQR 65.9-104.3); postoperative CKD (eGFR <60) developed in 42% (55/130). We performed various linear regression models to predict postoperative eGFR. The Quadratic model was the highest performing model, which relied only on preoperative GFR and the volumetric data for a RMSE of 15.3 on external validation corresponding to a clinical tool with an AUC of 0.89. CONCLUSION: Volumetric-based assessment provides information to predict postoperative eGFR. A tool based on this equation may assist surgical counseling regarding renal functional outcomes before renal tumor surgical procedures.

RESUMEN

PURPOSE: To validate the effect of listening to music on perceived anxiety and pain during office-based flexible cystoscopy using the State-Trait Anxiety Inventory (STAI) and the Visual Analog Scale (VAS), in a well-matched North American veteran patient population in a prospective, randomized fashion. PATIENTS AND METHODS: A total of 137 veteran patients receiving routine urologic care in a North American Veterans Affairs (VA) healthcare system were recruited over a 2-year period (June 2011 to June 2013). All patients were prospectively randomized to undergo office-based flexible cystoscopy with or without music. The music group consisted of 73 patients who listened to the same excerpt of classical music at the time of flexible cystoscopy; the nonmusic group consisted of 64 patients. RESULTS: The median postprocedural STAI anxiety scores between the music and nonmusic groups were statistically significantly different: 30 (range 23-39) and 35 (range 28-49), respectively (P=0.0017). The median postprocedural pain VAS score between the music and nonmusic groups reached statistical significance: 0 (range 0-1) and 2 (range 1-2), respectively (P<0.0001). The median delta STAI anxiety score was statistically significantly different between the music and nonmusic groups: 0 (range -3-0) and 2 (range 0-4), respectively (P<0.0001). CONCLUSIONS: This study demonstrates that listening to music decreases anxiety and pain associated with flexible cystoscopy in a North American VA patient population. We recommend incorporating music as an effective adjunct to other maneuvers used at the time of flexible cystoscopy to reduce anxiety and pain.

RESUMEN

BACKGROUND: Laparoscopic and robotic simple prostatectomy (SP) have been introduced with the aim of reducing the morbidity of the standard open technique. OBJECTIVE: To report a large multi-institutional series of minimally invasive SP (MISP). DESIGN, SETTING, AND PARTICIPANTS: Consecutive cases of MISP done for the treatment of bladder outlet obstruction (BOO) due to benign prostatic enlargement (BPE) between 2000 and 2014 at 23 participating institutions in the Americas and Europe were included in this retrospective analysis. INTERVENTION: Laparoscopic or robotic SP. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Demographic data and main perioperative outcomes were gathered and analyzed. A multivariable analysis was conducted to identify factors associated with a favorable trifecta outcome, arbitrarily defined as a combination of the following postoperative events: International Prostate Symptom Score <8, maximum flow rate >15ml/s, and no perioperative complications. RESULTS AND LIMITATIONS: Overall, 1330 consecutive cases were analyzed, including 487 robotic (36.6%) and 843 laparoscopic (63.4%) SP cases. Median overall prostate volume was 100ml (range: 89-128). Median estimated blood loss was 200ml (range: 150-300). An intraoperative transfusion was required in 3.5% of cases, an intraoperative complication was recorded in 2.2% of cases, and the conversion rate was 3%. Median length of stay was 4 d (range: 3-5). On pathology, prostate cancer was found in 4% of cases. Overall postoperative complication rate was 10.6%, mostly of low grade. At a median follow-up of 12 mo, a significant improvement was observed for subjective and objective indicators of BOO. Trifecta outcome was not significantly influenced by the type of procedure (robotic vs laparoscopic; p=0.136; odds ratio [OR]: 1.6; 95% confidence interval [CI], 0.8-2.9), whereas operative time (p=0.01; OR: 0.9; 95% CI, 0.9-1.0) and estimated blood loss (p=0.03; OR: 0.9; 95% CI, 0.9-1.0) were the only two significant factors. Retrospective study design, lack of a control arm, and limited follow-up represent major limitations of the present analysis. CONCLUSIONS: This study provides the largest outcome analysis reported for MISP for BOO/BPE. These findings confirm that SP can be safely and effectively performed in a minimally invasive fashion in a variety of healthcare settings in which specific surgical expertise and technology is available. MISP can be considered a viable surgical treatment in cases of large prostatic adenomas. The use of robotic technology for this indication can be considered in centers that have a robotic program in place for other urologic indications. PATIENT SUMMARY: Analysis of a large data set from multiple institutions shows that surgical removal of symptomatic large prostatic adenomas can be carried out with good outcomes by using robot-assisted laparoscopy.

RESUMEN

Open simple prostatectomy (OSP) is an effective and durable treatment for select patients with symptomatic benign prostatic hyperplasia (BPH) and large-volume prostate glands (>80 cc), yet is associated with clinically significant risk of bleeding, transfusion, prolonged hospital length of stay (LOS), and complications. Robotic-assisted simple prostatectomy (RASP) potentially reduces intraoperative blood loss and improves perioperative outcomes. Thirteen non-comparative series (Level 3 evidence) of RASP have established its safety and efficacy and have demonstrated substantially decreased risk of transfusion, complications, and mean LOS relative to published series of OSP, but with consistently longer operative times. Comparative outcomes data (Level 1 and Level 2 evidence), however, are relatively lacking. Thus, while RASP has advanced beyond the experimental stage, definitive outcomes studies are needed to establish its benefits and costs relative to OSP and transurethral surgery.

RESUMEN

BACKGROUND AND AIM OF THE STUDY: Half of all patients with infective endocarditis (IE) will require early surgical intervention, and another 40% will eventually undergo surgical treatment for their disease. Although the surgical management of IE is effective, the financial impact of the disease has never been assessed. METHODS: All patients who underwent valve surgery for native valve IE at the present authors' institution over a 10-year period (1996-2006) were reviewed retrospectively. Hospital charges were identified and adjusted to reflect US$ in 2006. A logistic regression analysis was performed to identify factors affecting charges and the patients' length of stay (LOS). RESULTS: A total of 369 patients (252 males, 117 females; mean age 53 +/- 15 years) underwent surgery for IE. Of these patients, 121 (33%) had preoperative renal failure and 70 (20%) were intravenous drug users. In addition, 159 patients (43%) had aortic IE, 112 (30%) had mitral IE, and 45 (12%) had both aortic and mitral valve IE. Right- and left-sided IE was identified in 42 patients (11%), and 11 (3%) had isolated right-sided IE. The median hospital charges were US$ 60,072 (interquartile range (IQR) US$ 39,386-103,960), with a median LOS of 15 days (IQR 9-29 days). Both, hospital charges and LOS were higher for patients undergoing emergent operations, or those with active IE (p < 0.001). The 30-day mortality was 2.7%. Regression analyses showed preoperative renal failure (p = 0.007), intraoperative transfusion (p = 0.028) and postoperative gastrointestinal complications (p < 0.001), renal failure (p = 0.012), heart block (p < 0.001), in-hospital mortality (p < 0.001), and patients undergoing emergent procedures (p < 0.001), or with active infection (p < 0.001) to be associated with significantly increased hospital charges. Factors that significantly affected LOS were other non-white race (p = 0.039), postoperative gastrointestinal complications (p = 0.001), stroke (p = 0.014), heart block (p < 0.001), and patients undergoing emergent procedures (p < 0.001) or with active infection (p < 0.001). CONCLUSION: The present series was among the largest to include patients with IE, and the first in which risk factors were assessed for increased hospital charges and resource utilization following surgery for endocarditis. Operations for IE are associated with a significant financial burden to the healthcare system, despite a relatively low percentage of complications. Patients with significant preoperative comorbidities, those with postoperative complications, and those who underwent emergent procedures or who had active IE, were associated with a prolonged LOS and increased hospital charges.

RESUMEN

BACKGROUND: Loeys-Dietz syndrome (LDS) is a recently recognized aggressive aortic disorder characterized by root aneurysm, arterial tortuosity, hypertelorism, and bifid uvula or cleft palate. The results of prophylactic root replacement using valve-sparing procedures (valve-sparing root replacement [VSRR]) in patients with LDS is not known. METHODS: We reviewed all patients with clinical and genetic (transforming growth factor-ß receptor mutations) evidence of LDS who underwent VSRR at our institution. Echocardiographic and clinical data were obtained from hospital and follow-up clinic records. RESULTS: From 2002 to 2009, 31 patients with a firm diagnosis of LDS underwent VSRR for aortic root aneurysm. Mean age was 15 years, and 24 (77%) were children. One (3%) patient had a bicuspid aortic valve. Preoperative sinus diameter was 3.9±0.8 cm (z score 7.0±2.9) and 2 (6%) had greater than 2+ aortic insufficiency. Thirty patients (97%) underwent reimplantation procedures using a Valsalva graft. There were no operative deaths. Mean follow-up was 3.6 years (range, 0 to 7 years). One patient required late repair of a pseudoaneurysm at the distal aortic anastomosis, and 1 had a conversion to a David reimplantation procedure after a Florida sleeve operation. No patient suffered thromboembolism or endocarditis, and 1 (3%) patient experienced greater than 2+ late aortic insufficiency. No patient required late aortic valve repair or replacement. CONCLUSIONS: Loeys-Dietz syndrome is an aggressive aortic aneurysm syndrome that can be addressed by prophylactic aortic root replacement with low operative risk. Valve-sparing procedures have encouraging early and midterm results, similar to those in Marfan syndrome, and are an attractive option for young patients.

RESUMEN

BACKGROUND: Bleeding complications are a major source of morbidity and reoperation after left ventricular assist device (LVAD) implantation, yet remain poorly characterized in patients receiving LVADs. We assessed bleeding complications in an institutional cohort of LVAD patients. METHODS: We reviewed patients who received continuous-flow (CF) LVADs at our institution (October 2004 to May 2009). Intraoperative and postoperative transfusion requirements (packed red blood cells, fresh frozen plasma, and platelets), chest tube output, and reoperation for bleeding complications were assessed. Univariate and multivariable Cox proportional hazard analysis assessed the impact of intraoperative bleeding on mortality. A subset of our patient population underwent delayed sternal closure as opposed to primary closure and an analysis of reoperation for bleeding was undertaken stratifying patients by approach to closure. RESULTS: Eighty-six CF LVADs were implanted over our study period. Patients had poor preoperative cardiac function and high preoperative risk indices. Patients receiving LVADs had high intraoperative (11.6 ± 7.5 units) and postoperative (15.6 [±12.6] units in the first week) blood product requirements, as well as significant chest tube output (5,880 [±4,480] milliliters in the first week). On multivariable analysis, intraoperative packed red blood cell transfusions were a significant predictor of mortality. Eleven (28%) patients undergoing primary sternal closure required reoperation for bleeding, while delayed sternal closure patients generally had resolution of bleeding prior to sternal closure. The incidence of gastrointestinal bleeding was 28% at one year. CONCLUSIONS: On multivariable analysis, intraoperative packed red blood cell transfusions were a significant predictor of 30-day and one-year mortality, while chest tube output during the first postoperative 48 hours predicted 30-day but not one-year mortality.

RESUMEN

BACKGROUND: Recent published results suggest no additive benefit to surgical ventricular restoration (SVR) when combined with coronary artery bypass grafting. However, there may still be a subgroup of patients with severe heart failure who can benefit from this procedure. We reviewed our institutional experience with SVR to determine early and late outcomes based on volume reduction. METHODS: We retrospectively reviewed our SVR patients (January 2002 to April 2008) with follow-up to March 2009. Baseline comorbidities, operative data, and postoperative outcomes were assessed by chart review, phone calls, and mailings. Survival was modeled using the Kaplan-Meier method. Cardiac magnetic resonance imaging, myocardial perfusion scans, and echocardiography assessed cardiac function, candidacy for SVR, and volume reduction. RESULTS: We reviewed 87 consecutive SVR patients (69 men). Mean age at operation was 61.1 years. Preoperatively, all patients had congestive heart failure, with 80 (92%) at New York Heart Association III/IV. All patients underwent preoperative viability studies. Three-vessel occlusion exceeding 50% was present in 69 (79%). After SVR, ejection fraction improved from 0.236 to 0.332 (p<0.001). Preoperative and postoperative magnetic resonance imaging in 26 patients (30.0%) showed a 30.8% reduction in left ventricular end systolic volume index. At follow-up, 51 of 66 (77%) improved to New York Heart Association I/II. One intraoperative death occurred. Preoperative left ventricular end systolic volume index of 80 to 120 was associated with improved survival (73% at 3 years). CONCLUSIONS: SVR is a surgical option for appropriately selected patients with severe congestive heart failure. In these high-risk patients, SVR successfully increased ejection fraction and decreased symptoms. A left ventricular end systolic volume index of 80 to 120 may be the ideal range for SVR procedures.

RESUMEN

Valve-sparing root replacement (VSRR) is an attractive option for aortic aneurysm in children with low-operative risk, but mid- and late-term results are not yet known. Between 1997 and 2009, 56 children (mean age 11.5 years) underwent VSRR at our institution. Twenty-six (46.4%) had Marfan syndrome and 24 (42.8%) had Loeys-Dietz syndrome. Mean preoperative max sinus diameter was 4.2±0.8 cm (Z-score 7.7±2.9). Five (8.9%) had >2+ aortic insufficiency (AI). Two (3.6%) underwent David I reimplantation with a straight-tube, 12 (21.4%) had a Yacoub remodeling procedure, and 42 (75.0%) had reimplantation using a Valsalva-graft. There were one (1.8%) operative and three (5.4%) late deaths. One patient required reoperation for bleeding and one required late repair of a distal pseudoaneurysm. Mean follow-up was 5.2 years (range 0-12 years). No patients suffered thromboembolic events or had endocarditis. Of the 12 remodeling patients, four (33.3%) developed >2+ AI and required aortic valve repair or replacement. No patient developed >2+ AI after reimplantation. VSRR in children is a safe alternative to aortic root replacement with mechanical or biological prostheses. In this particular group of patients with connective tissue disorders and proclivity toward annular dilation and late AI, reimplantation is superior to remodeling.

RESUMEN

OBJECTIVE: To analyse consecutive cases of robotic-assisted laparoscopic prostatectomy (RALP), present the incidence of nerve-sparing-related positive surgical margins (SM+), include visual cues that might assist in smoothly changing to the robotic platform, and discuss the scientific rationale for 'intersensory integration' which might explain the 'reverse Braille' phenomenon, i.e. the ability to feel when vision is greatly enhanced, as the lack of tactile feedback during RALP is often cited as a disadvantage of robotic surgery, interfering with a surgeon's ability to make intraoperative oncological decisions. PATIENTS AND METHODS: Data from 1340 consecutive patients undergoing RALP from one institution were analysed and trends for positive posterolateral SM+ (PLSM+) were correlated with oncological variables before and after RALP. A sample of patient slides were reviewed by a extramural pathologist. Multivariate regression modelling was used to compare the projected rates of PLSM+ vs the actual rate, given the effect of a conscious effort to use visual cues. Finally, video recordings of the procedure were systematically reviewed and correlated with anatomical and histopathological images in an integrated session involving the surgeon and the pathology team. RESULTS: The incidence of PLSM+ was 2.1%, which gradually declined to 1.0% in the last 100 patients. The reduction in PLSM+ occurred despite an increased rate of high-risk tumours operated on during this period. Forecasting analysis showed that the actual PLSM+ rate declined by half in the most recent 1000 patients, due to an integrated effort involving the use of visual cues during surgery. The following visual cues were considered important; appreciation of periprostatic (lateral prostatic) fascial compartments; colour and texture of the tissue; periprostatic veins as a landmark for athermal dissection; signs of inflammation; and a freely separating bloodless plane showing loose shiny areolar tissue. CONCLUSION: Adapting to the robotic platform is easy and there is no compromise of the oncological safety of this procedure. Experienced surgeons can use visual cues to assist during nerve-sparing RALP and achieve low PLSM+ rates.

RESUMEN

BACKGROUND: The Leitz-Miller (LM), Columbia (COL), Acute Physiology and Chronic Health Evaluation II (APACHE II), Interagency Registry for Mechanically Assisted Circulatory Support (INTERMACS), and Seattle Heart Failure Model (SHFM) risk scores have been used to risk stratify patients with pulsatile-flow left ventricular assist devices (LVAD). We assessed the predictive ability of these scores in a cohort of continuous-flow LVAD patients. METHODS: Preoperative scores were calculated from prospective data of patients who received continuous-flow LVADs between June 2000 and May 2009. Cox proportional hazard analysis assessed the effect of preoperative variables and scores on 30-day, 90-day, and 1-year mortality. Patients were stratified by score into low- and high-risk groups. Survival was modeled using the Kaplan-Meier method. RESULTS: During the study period, 86 continuous-flow LVADs were implanted. The mean (+/- standard deviation) preoperative scores were: COL, 1.05 +/- 1.59; LM, 11.9 +/- 5.4; APACHE II, 15.6 +/- 4.3; INTERMACS, 2.64 +/- 1.01; and SHFM, 2.97 +/- 1 .42. On univariate analysis, the SHFM score best differentiated low- and high-risk patients at all mortality end points; the INTERMACS and APACHE II scores were predictive for 90-day and 1-year mortality. On multivariable analysis, SHFM (hazard ratio [HR], 1.50; 95% confidence interval [CI], 1.02 to 2.21; p = 0.04) and APACHE II (HR, 1.10; 95% CI, 1.01 to 1.21; p = 0.04) predicted 1-year mortality. CONCLUSIONS: Among the LM, COL, APACHE II, INTERMACS, and SHFM scores, the best predictor of mortality in a single institutional cohort of continuous-flow LVAD patients was the SHFM score.
