RESUMO
A previously healthy woman in late adolescence presented to the emergency department with stroke-like symptoms following a two-month history of bilateral foot pain and oedema, accompanied by a macular rash and progressive lower extremity weakness. On further investigation, she was found to have multiple cerebral emboli and a left atrial myxoma fixed to the interatrial septum. The patient subsequently underwent urgent surgical excision of the myxoma. On follow-up, her cutaneous and neurological symptoms were significantly improved. This case suggests that, in the presence of a vasculitic rash without evident or obvious cause, cardiac myxoma should be included in the differential diagnosis.

OBJECTIVES: Redo sternotomy and explantation of left ventricular assist devices (LVAD) for heart transplantation (HT) involve prolonged dissection, potential injury to mediastinal structures and/or bleeding. Our study compared a complete expanded polytetrafluoroethylene (ePTFE) wrap versus minimal or no ePTFE during LVAD implantation, on outcomes of subsequent HT. METHODS: Between July 2005 and July 2018, 84 patients underwent a LVAD implant and later underwent HT. Thirty patients received a complete ePTFE wrap during LVAD implantation (Group 1), and 54 patients received either a sheet of ePTFE placed in the anterior mediastinum or no ePTFE (Group 2). RESULTS: Baseline characteristics were similar between Groups 1 and 2. Surgeons reported subjective improvements in speed, predictability, and safety of dissection with complete ePTFE compared with minimal or no ePTFE. Time from incision to initiation of cardiopulmonary bypass (CPB) were similar between groups (97 ± 38 vs. 89 ± 29 min, p = .3). Injury to mediastinal structures during the dissection was similar between groups (10% vs. 11%, p > .9). While surgeons reported less intraoperative bleeding in Group 1 (43% vs. 61%), this trend did not reach significance (p = .1). In-hospital mortality, intensive care unit length of stay and hospital length of stay were similar between both groups. CONCLUSIONS: In patients undergoing LVAD explant-HT, there was a trend toward reduced surgeon reported intraoperative bleeding with ePTFE placement. Despite qualitatively reported greater ease and speed of mediastinal dissection with ePTFE membrane placement, time to initiation of CPB did not differ, likely because surgeons remained cautious, allowing extra time for unanticipated difficulties.

Technical details for complex cardiac tumor resection are sparse. We describe the operative technique of modified autotransplantation for resection of a complex pericardial synovial sarcoma in a 63-year-old, Caucasian female. Surgical exposure demonstrated tumor origin at the superior cavoatrial junction and invasion of the aorta, main pulmonary artery, superior pulmonary veins, and left atrial roof. Full macroscopic surgical resection was achieved. The patient received adjuvant radiation for microscopic positive margins and remains alive and with no tumor progression at one year postoperatively. We conclude that modified autotransplantation is a challenging but effective surgical technique when performed with careful patient selection and availability of skilled, cardiothoracic surgeons at a cardiac center of excellence.

BACKGROUND: Sarcopenia, the age-related loss of skeletal muscle mass/function, has been identified as a marker of frailty. We examined the association between sarcopenia and adverse events following transcatheter aortic valve implantation (TAVI). METHODS: A retrospective cohort study was conducted at Toronto General Hospital. All patients who underwent TAVI in the time period 2007-2017 with preoperative computed tomography were included. Skeletal muscle index (SMI) was calculated radiographically using psoas muscle area at the L3 vertebral level, divided by height. Various measures of sarcopenia, including mean SMI, SMI below the sex-specific median, and SMI in the lowest sex-specific quartile were calculated. The primary outcome was postoperative adverse events, defined as a composite of in-hospital mortality and morbidity including cardiovascular, pulmonary, neurologic, access-related, and gastrointestinal complications. Univariate and multivariate logistic regression were performed to determine the association between sarcopenia and adverse events. RESULTS: A total of 468 patients (mean age: 80.7 years) were included. Baseline comorbidity burden was high, particularly congestive heart failure (93.4%). Postoperative adverse events occurred in 62 patients (13.2%). Univariate logistic regression demonstrated that postoperative adverse events were correlated with mean SMI (odds ratio [OR] 0.81, 95% confidence interal [CI] 0.66-0.97), events were less than the SMI (OR 2.16, 95% CI 1.24-3.84), and SMI in the sex-specific lowest quartile (OR 2.34, 95% CI 1.33-4.07). On multivariate analysis, SMI in the sex-specific lowest quartile was an independent predictor of adverse events (OR 2.53, 95% CI 1.41-4.50). CONCLUSIONS: Sarcopenia defined by radiologic psoas muscle measurements was independently associated with in-hospital mortality and morbidity following TAVI.
CONTEXTE: La sarcopénie, soit la perte de masse et de fonction des muscles squelettiques liée à l'âge, a été identifiée comme un marqueur de fragilité. Nous avons examiné l'association entre la sarcopénie et les événements indésirables suivant l'implantation valvulaire aortique par cathéter (IVAC). MÉTHODOLOGIE: Une étude de cohorte rétrospective a été menée au Toronto General Hospital. Tous les patients ayant subi une IVAC avec tomodensitométrie préopératoire au cours de la période 2007-2017 ont été inclus. L'indice de masse musculaire squelettique (IMMS) a été calculé par radiographie en utilisant la surface du psoas au niveau de la vertèbre L3, divisée par la taille. Diverses mesures de la sarcopénie, y compris l'IMMS moyen, l'IMMS sous la médiane selon le sexe et l'IMMS dans le quartile inférieur selon le sexe, ont été calculées. Le critère d'évaluation principal était les événements indésirables postopératoires, définis comme un critère composite comprenant la mortalité et la morbidité à l'hôpital, notamment les complications cardiovasculaires, pulmonaires, neurologiques, gastro-intestinales et liées à l'accès vasculaire. Des régressions logistiques univariée et multivariée ont été effectuées pour déterminer l'association entre la sarcopénie et les événements indésirables. RÉSULTATS: Un total de 468 patients (âge moyen : 80,7 ans) ont été inclus. Le fardeau de comorbidité au départ était élevé, en particulier pour ce qui est de l'insuffisance cardiaque congestive (93,4 %). Des événements indésirables postopératoires sont survenus chez 62 patients (13,2 %). La régression logistique univariée a montré que les événements indésirables postopératoires étaient en corrélation avec un IMMS moyen (rapport des cotes [RC] : 0,81, intervalle de confiance [IC] à 95 % : 0,66 à 0,97), un IMMS sous la médiane selon le sexe (RC : 2,16; IC à 95 % : 1,24 à 3,84) et un IMMS dans le quartile inférieur selon le sexe (RC : 2,34; IC à 95 % : 1,33 à 4,07). Lors de l'analyse multivariée, un IMMS situé dans le quartile inférieur selon le sexe était un prédicteur indépendant d'événements indésirables (RC : 2,53; IC à 95 % : 1,41 à 4,50). CONCLUSIONS: La sarcopénie définie par les mesures radiologiques du psoas était indépendamment associée à la mortalité et à la morbidité à l'hôpital à la suite d'une IVAC.
RESUMO
BACKGROUND: Transvenous lead extraction can have serious adverse events, such as cardiac or vascular perforation. Risk factors have not been well characterized. OBJECTIVE: The purpose of this study was to identify factors associated with perforation and death, and to characterize lead extraction in a large contemporary population. METHODS: We performed a retrospective multicenter study examining patients undergoing lead extraction at 8 Canadian institutions from 1996 through 2016. Demographic and clinical data were used to identify variables associated with perforation and mortality using logistic regression modeling. RESULTS: A total of 2325 consecutive patients (age 61.9 ±16.5 years) underwent extraction of 4527 leads. Perforation rate was 2.7% (63/2325) and 30-day mortality was 1.6% (38/2325), with mortality of 0.4% due to perforation (10/2325). Variables associated with perforation included no previous cardiac surgery (odds ratio [OR] 3.33; 95% confidence interval [CI] 1.54-7.19; P = .002), female sex (OR 3.27; 95% CI 1.91-5.60; P <.001); left ventricular ejection fraction ≥40% (OR 2.81; 95% CI 1.28-6.14; P = .010); lead age >8 years (OR 2.64; 95% CI 1.52-4.60; P <.001); ≥2 leads extracted (OR 2.49; 95% CI 1.23-5.04; P = .011); and diabetes (OR 2.12; 95% CI 1.16-3.86; P = .014). Variables associated with death included infection as indication for extraction (OR 3.85; 95% CI 1.38-10.73; P = .010); anemia (OR 3.14; 95% CI 1.38-6.61; P = .003), and patient age (OR 1.04; 95% CI 1.01-1.07; P = .012). CONCLUSION: Risk factors associated with perforation in lead extraction include no history of cardiac surgery, female sex, preserved left ventricular ejection fraction, lead age >8 years, ≥2 leads extracted, and diabetes.

The authors report a 27-year-old woman with a remote left femoral osteosarcoma and amputation above the left knee who presented with a large right ventricular mass. Initial evaluation with thoracic CT was inconclusive regarding thrombus versus tumor, but metastatic osteosarcoma was suggested by findings at transthoracic echocardiography, cardiac CT, and cardiac MRI. The patient underwent tumor debulking, and osteosarcoma was confirmed with pathologic examination. She responded to chemotherapy, which resulted in reduction in size of the residual right ventricular tumor and of a few pulmonary metastases. Following induction chemotherapy, patient remains well undergoing maintenance therapy with an oral tyrosine kinase inhibitor.

RESUMO
Ventricular remodeling following myocardial infarction (MI) is a major cause of heart failure, a condition prevalent in older individuals. Following MI, immune cells are mobilized to the myocardium from peripheral lymphoid organs and play an active role in orchestrating repair. While the effect of aging on mouse bone marrow (BM) has been studied, less is known about how aging affects human BM cells and their ability to regulate repair processes. In this study, we investigate the effect aging has on human BM cell responses post-MI using a humanized chimeric mouse model. BM samples were collected from middle aged (mean age 56.4 ± 0.97) and old (mean age 72.7 ± 0.59) patients undergoing cardiac surgery, CD34+/- cells were isolated, and NOD-scid-IL2rγnull (NSG) mice were reconstituted. Three months following reconstitution, the animals were examined at baseline or subjected to coronary artery ligation (MI). Younger patient cells exhibited greater repopulation capacity in the BM, blood, and spleen as well as greater lymphoid cell production. Following MI, CD34+ cell age impacted donor and host cellular responses. Mice reconstituted with younger CD34+ cells exhibited greater human CD45+ recruitment to the heart compared to mice reconstituted with old cells. Increased cellular responses were primarily driven by T-cell recruitment, and these changes corresponded with greater human IFNy levels and reduced mouse IL-1ß in the heart. Age-dependent changes in BM function led to significantly lower survival, increased infarct expansion, impaired host cell responses, and reduced function by 4w post-MI. In contrast, younger CD34+ cells helped to limit remodeling and preserve function post-MI.

A 58-year-old man with a history of hypertension, dyslipidemia, and an obtuse marginal branch coronary stent developed the sudden onset of chest pain. A contrast computed tomography demonstrated a penetrating ulcer of nondilating ascending aorta and a small pericardial effusion. Coronary angiography showed three-vessel disease. At emergency surgery, there was blood in the pericardial sac and the whole of the ascending aorta had hematoma with no evidence of tamponade. We performed a hemiarch replacement under circulatory arrest and concomitant coronary artery bypass grafting. The left side of the proximal arch had ruptured just beyond the pericardial reflection.

BACKGROUND AND AIM: Lipomatous hypertrophy of the interatrial septum (LHIS), a fatty tumor, is usually diagnosed on both echo and CT/MRI imaging. Cases of LHIS located outside of the interatrial septum are extremely rare and rarer still are these cases large enough to cause symptoms. The clinical literature demonstrates a misunderstanding that fatty tumors outside the intra-atrial area represent lipomas. However, pathologic understanding of these fatty tumors is clear and is based on microscopic findings. METHODS: The tumor was removed by diving the base of attachment at the left ventricular apex via a median sternotomy on cardiopulmonary bypass. RESULTS: The patient made an uneventful recovery and remains well at 6 months postoperatively. CONCLUSIONS: On rare occasions, LHIS can arise from outside the interatrial septum. An LHIS can be differentiated from a lipoma by the presence of entrapped cardiac myocytes in LHIS, making it a pathological, rather than an anatomic, diagnosis.

OBJECTIVES: Off-pump coronary artery bypass (OPCAB) may benefit select high-risk patients. We sought to analyze the long-term outcomes of OPCAB versus on-pump coronary artery bypass (ONCAB) in patients with moderate renal failure. METHODS: A retrospective cohort analysis of primary isolated CAB surgery performed in Ontario, Canada, from October 2008 to March 2016 in the CorHealth Ontario Cardiac Registry identified 50,115 cases. Of these, 7782 (15.5%) had estimated glomerular filtration rate (eGFR) of 30 to 59 mL/min/1.73 m2. OPCAB was compared to ONCAB after propensity score matching. RESULTS: Following propensity score matching, 1578 patient pairs were formed. Total number of bypass grafts was higher in ONCAB (3.31 ± 1.01 vs 3.12 ± 1.14; P < .01) and more arterial grafts were used in OPCAB (1.55 ± 0.71 vs 1.14 ± 0.58; P < .01). OPCAB was associated with lower rate of in-hospital stroke (0.7% vs 2.2%; P < .01), renal failure requiring dialysis (1.2% vs 2.9%; P < .01), and blood transfusion (52.4% vs 69.3%; P < .01). There was no difference in perioperative mortality (2.4% vs 3.0%; P = .36) between OPCAB and ONCAB, respectively. At 8-year follow-up, survival probability was not different when comparing OPCAB versus ONCAB: 62% versus 65%, respectively (hazard ratio, 0.98; 95% confidence interval, 0.84-1.13; P = .38). Cumulative incidence of permanent dialysis did not differ at 8-year follow-up: 7% versus 7%, respectively (hazard ratio, 1.01; 95% confidence interval, 0.72-1.43; P = .74. CONCLUSIONS: OPCAB is associated with improved in-hospital renal outcomes, but is not associated with changes in short- or long-term mortality, or with the long-term cumulative incidence of end-stage renal failure requiring permanent dialysis in patients with moderate renal failure.

Cardiac tumors are rare. Most surgeons will encounter few primary cardiac tumors outside of myxomas. This article offers the authors' approach to simple and complex primary and secondary cardiac tumors. Symptoms of primary cardiac tumors are primarily determined by tumor size and anatomic location. Most simple primary tumors and some complex primary tumors are best managed by surgical resection. Secondary tumors are 30 times more frequent than primary cardiac tumors. Surgical resection of secondary tumors is rational in a few highly selected patients. For complex primary and secondary tumors, the authors recommend referral to an experienced multidisciplinary cardiac tumor team.

OBJECTIVES: Vascular complications (VCs) remain a significant cause of morbidity in transcatheter aortic valve implantation (TAVI) patients and are associated with worse outcomes. This research analysed the incidence, impact, and predictors of VCs in transfemoral cases. METHODS: A retrospective chart review was performed of 388 consecutive TAVI patients between January 2007 and April 2015, which included 237 transfemoral cases. Major and minor VCs were characterised according to the Valve Academic Research Consortium (VARC) guidelines. Logistic regression was completed to identify predictors of VCs. RESULTS: While VCs occurred in 68 (28.7%) cases, only seven (3.38%) were classified as major complications. Twenty-six (10.9%) of these complications occurred intra-operatively, with four being major (1.6%) and 22 minor (9.3%). Post-operative VCs occurred in 42 cases (17.2%), with three (1.3%) being major. Procedures to correct VCs occurred in 10 (4.2%) cases, with the majority (90%) being surgical and the remainder being treated by endovascular techniques. Nine surgical procedures, predominantly embolectomy, were performed to correct post-operative complications. Female gender was a predictor of all major VCs (B = -2.1, p < .006). Further, a logistic regression analysis found that when the largest sheath was located on the left side, there were increased minor post-operative complications (B = -0.99, p = .007). Dissections and haematomas made up the majority of VCs. Thirty day mortality was six patients (n = 2.5%), and peri-operative VCs were significantly correlated with 30 day mortality (p = .001, R = 0.21). The 30 day readmission rate comprised nine patients (3.8%), with three (1.3%) due to VCs, including haematomas and groin infections. CONCLUSIONS: VCs contribute to operative morbidity in TAVI patients. This study demonstrated low major VC rates over an eight year period. Left sided location of largest sheath size and female gender were predictors of VC.

BACKGROUND: Primary cardiac sarcoma (PCS) is a rare but often fatal disease. The current study aimed to analyze the impact of baseline demographics, local and systemic therapies in a contemporary cohort. METHODS: Clinical records of PCS across six institutions in three continents were reviewed. Kaplan-Meier method was used to estimate survival. Cox proportional hazard model was used to determine variables impacting progression-free survival (PFS) or overall survival (OS). RESULTS: Sixty-one patients with PCS (1996-2016) were identified. The median age at diagnosis was 46 (range 18-79); 36% (n = 22) presented with metastatic disease. The most common histology was angiosarcoma (n = 24, 39%). A total of 46 patients received surgery (75%) but only 5 (8%) patients achieved R0 resection. Multi-modality treatment to the primary tumor was given to 28 patients (46%; localized disease 23/39 (59%); metastatic disease 5/22 (23%)). The median OS for the entire cohort was 17.5 months (95% CI 9.5-20.6), with seven (11%) patients surviving longer than 36 months. On multi-variate analysis, age <65 (P = 0.01) was the only significant favorable prognostic factor. For first-line palliative chemotherapy, the median PFS was 4.4 months (95% CI 2.9-7.7 months). The best response for first-line chemotherapy was 32% (CR = 1, PR = 9). No significant improvement in OS was identified in patients presenting throughout the 20-year period of this review. CONCLUSION: Younger age at diagnosis was associated with improved outcome although the prognosis of PCS remains poor. Given the lack of improvement in survival, further dedicated research is required.

OBJECTIVE(S): This study was designed to compare 2 different perioperative analgesia strategies with respect to the incidence of postoperative delirium after a transapical approach for transcatheter aortic valve replacement (TAVR). The authors hypothesized that perioperative thoracic paravertebral analgesia with a local anesthetic would decrease opioid consumption and in turn reduce the incidence of postoperative delirium when compared with systemic opioid-based analgesia after a transapical TAVR procedure. DESIGN: Prospective, randomized controlled clinical trial. SETTING: Tertiary referral center, university hospital. PARTICIPANTS: The study comprised 44 patients undergoing a transapical TAVR procedure. Patients with a history of serious mental illness, delirium, and severe dementia and/or patients with contraindications to regional anesthesia were excluded. INTERVENTIONS: Patients were randomly assigned to either the paravertebral group (perioperative continuous thoracic paravertebral block with local anesthetic) or the patient-controlled analgesia group (systemically administered opioids) using a computer-generated randomization code in blocks of four patients. MEASUREMENTS AND MAIN RESULTS: Assessment of postoperative delirium was performed by trained research staff using the confusion assessment method for intensive care unit preoperatively and postoperatively every 12 hours or more often if needed according to the patient's condition during the first 7 postoperative days or until discharge. Pain was assessed with a 10 cm Visual Analog Scale pain score system during the 48 hours postoperatively. The sedation level was assessed using the Sedation Agitation Scale during the same period. Overall postoperative delirium was detected in 12/44 (27%) patients, with 7/22 (32%) in the patient-controlled analgesia and 5/22 (23%) in the paravertebral groups, respectively (pâ¯=â¯0.73). Both groups were similar with respect to demographic data, preoperative medications, and comorbidities. Paravertebral analgesia was associated with an opioid-sparing effect during surgery and during the 48-hour postoperative period. Sedation and pain scores were similar between the 2 groups. In addition, paravertebral analgesia was associated with earlier extubation times; however, the overall morbidity and mortality were similar between the 2 groups. CONCLUSIONS: Paravertebral analgesia in patients undergoing transapical TAVR procedures appears to have an opioid-sparing effect. However, it did not translate into a statistically significant decrease in the rate of postoperative delirium.
