RESUMEN
Patients with advanced ischemic cardiomyopathy manifesting as left ventricular dysfunction exist along a spectrum of severity and risk, and thus decision-making surrounding optimal management is challenging. Treatment pathways can include medical therapy as well as revascularization through percutaneous coronary intervention or coronary artery bypass grafting. Additionally, temporary and durable mechanical circulatory support, as well as heart transplantation, may be optimal for select patients. Given this spectrum of risk and the complexity of treatment pathways, patients may not receive appropriate therapy given their perceived risk, which can lead to sub-satisfactory outcomes. In this review, we discuss the identification of high-risk ischemic cardiomyopathy patients, along with our programmatic approach to patient evaluation and perioperative optimization. We also discuss our strategies for therapeutic decision-making designed to optimize both short- and long-term patient outcomes.

OBJECTIVE: We aim to report our institutional outcomes of single-staged combined liver transplantation (LT) and cardiac surgery (CS). SUMMARY BACKGROUND DATA: Concurrent LT and CS is a potential treatment for combined cardiac dysfunction and end-stage liver disease, yet only 54 cases have been previously reported in the literature. Thus, the outcomes of this approach are relatively unknown, and this approach has been previously regarded as extremely risky. METHODS: Thirty-one patients at our institution underwent combined cardiac surgery and liver transplant. Patients with at least one-year follow-up were included. The Leave-One-Out Cross-Validation (LOOCV) machine-learning approach was used to generate a model for mortality. RESULTS: Median follow-up was 8.2 years (IQR 4.6-13.6 y). One- and five-year survival was 74.2% (N=23) and 55% (N=17), respectively. Negative predictive factors of survival included recipient age>60 years (P=0.036), NASH-cirrhosis (P=0.031), Coronary Artery Bypass-Graft (CABG)-based CS (P=0.046) and pre-operative renal dysfunction (P=0.024). The final model demonstrated that renal dysfunction had a relative weighted impact of 3.2 versus CABG (1.7), age ≥60y (1.7) or NASH (1.3). Elevated LT+CS risk score was associated with an increased five-year mortality after surgery (AUC=0.731, P=<0.001). Conversely, the widely accepted STS-PROM calculator was unable to successfully stratify patients according to 1- (P>0.99) or 5-year (P=0.695) survival rates. CONCLUSIONS: This is the largest series describing combined LT+CS, with joint surgical management appearing feasible in highly selected patients. CABG and pre-operative renal dysfunction are important negative predictors of mortality. The four-variable LT+CS score may help predict patients at high risk for post-operative mortality.
RESUMEN
PURPOSE OF REVIEW: The surgical management of patients undergoing coronary artery bypass grafting (CABG) with low ejection fraction presents unique challenges that require meticulous attention to details and good surgical technique and judgement. This review details the latest evidence and best practices in the care of such patients. RECENT FINDINGS: CABG in patients with low ejection fraction carries a significant risk of perioperative mortality and morbidity related to the development of postcardiotomy shock. Preoperative optimization with pharmacological or mechanical support is required, especially in patients with cardiogenic shock. Rapid and complete revascularization is what CABG surgeons aim to achieve. Multiple arterial revascularization should be reserved to selected patients. Off-pump CABG, on-pump breathing heart CABG, and new cardioplegic solutions remain of uncertain benefit compared with traditional CABG. SUMMARY: Tremendous advancements in CABG allowed surgeons to offer revascularization to patients with severe left ventricular dysfunction and multivessel disease with acceptable risk. Despite that, there is a lack of comprehensive and robust studies particularly on long-term outcomes. Individualized patient assessment and a heart team approach should be used to determine the optimal surgical strategy for each patient.

BACKGROUND: Intracranial hemorrhage (ICH) is a frequent complication in patients with an implanted left ventricular assist device (LVAD) for advanced heart failure. Bloodstream infection is known to be associated with ICH in patients with LVAD, but its effects on ICH-associated mortality are unknown. We compared characteristics and mortality of infection-associated, traumatic, and spontaneous hemorrhages. METHODS: Patients in an LVAD registry at a tertiary care center were reviewed for this cohort study. ICH included intraparenchymal hemorrhage, subarachnoid hemorrhage, and subdural hemorrhage. Hemorrhages were categorized into infectious, traumatic, and spontaneous by the presence or absence of concurrent device-associated infection or antecedent trauma. RESULTS: Of 683 patients with an LVAD, 73 experienced ICH (10.7%). Intraparenchymal hemorrhage was the most prevalent (72%), followed by subarachnoid hemorrhage (27%) and subdural hemorrhage (23%), with multiple concurrent hemorrhage subtypes in 16 patients (22%). Median time from implantation to ICH was shorter in spontaneous ICH than in infection-associated ICH (100 days vs. 252 days, p = 0.048). The prevalence of the different subtypes of ICH were similar between spontaneous and infection-associated ICH, and no differences were seen in mortality between the different causes of ICH. CONCLUSIONS: Although spontaneous ICH occurred earlier after LVAD implantation than infection-associated ICH, no difference in mortality was seen between the different causes of ICH.

BACKGROUND: Therapies for advanced heart failure (AHF) improve the likelihood of survival in a growing population of patients with stage D heart failure (HF). Successful implementation of these therapies is dependent upon timely and appropriate referrals to AHF centers. METHODS: We performed a retrospective analysis of patients referred to 9 AHF centers for evaluation for AHF therapies. Patients' demographics, referring providers' characteristics, referral circumstances, and evaluation outcomes were collected. RESULTS: The majority of referrals (nâ¯=â¯515) were male (73.4%), and a majority of those were in the advanced state of the disease: very low left ventricular ejection fraction (<20% in 51.5%); 59.4% inpatient; and high risk Interagency Registry for Mechanically Assisted Circulatory Support (INTERMACS) profiles (74.5% profile 1-3). HF cardiologists (49.1%) were the most common originating referral source; the least common (4.9%) were electrophysiologists. Common clinical triggers for referral included worsening HF (30.0%), inotrope dependence (19.6%), hospitalization (19.4%), and cardiogenic shock (17.8%). Most commonly, AHF therapies were not offered because patients were too sick (38.0%-45.1%) or for psychosocial reasons (20.3%-28.6%). Compared to non-HF cardiologists, patients referred by HF cardiologists were offered an AHF therapy more often (66.8% vs 58.4%, Pâ¯=â¯0.0489). Of those not offered any AHF therapy, 28.4% received home inotropic therapy, and 14.5% were referred to hospice. CONCLUSIONS: In this multicenter review of AHF referrals, HF cardiologists referred the most patients despite being a relatively small proportion of the overall clinician population. Late referral was prevalent in this high-risk patient population and correlates with worsened outcomes, suggesting a significant need for broad clinician education regarding the benefits, triggers and appropriate timing of referral to AHF centers for optimal patient outcomes.

In this document, we outline the challenges faced by patients and clinicians in heart failure, specifically centered around the needed coordination of care among the various subspecialties within cardiovascular medicine. We call for a more organized and collaborative effort among clinicians in primary care, general cardiology, electrophysiology, interventional cardiology, cardiothoracic surgery, cardiac imaging, and heart failure-all caring for mutual patients. Care is contextualized within the framework of two phases: a cardiomyopathy phase and an advanced heart failure phase, each of which lends to different considerations in therapy. Ultimately multidisciplinary coordinated care within cardiovascular medicine may lead to greater patient and clinician satisfaction as well as improved outcomes, but this remains to be investigated.

BACKGROUND: Little is known about graft patency after coronary artery bypass grafting (CABG) performed in patients on dialysis. Our aim was to assess patency of internal thoracic artery (ITA) grafts and saphenous vein grafts (SVGs) in these patients. METHODS: From 1/1997 to 1/2018, 500 patients on dialysis underwent primary CABG with or without concomitant procedures at Cleveland Clinic, 40 of whom had 48 postoperative angiograms for recurrent ischemic symptoms. Complete follow-up was obtained on all but 1 patient lost to follow-up 1 y after CABG. Thirty-six ITA grafts and 65 SVGs were evaluable for stenosis and occlusion. RESULTS: Two of 40 patients (5%) had emergency CABG; 3 (7.5%) with calcified aortas had a change in operative strategy to avoid ascending aortic manipulation, 2 (5%) had poor conduit quality, and 12 (30%) had severe diffuse atherosclerotic disease with calcification of the coronary targets causing technical difficulties. Thirty-three patients (82%) were bypassed with an in situ ITA and 3 (7.5%) had a free ITA graft. Three of 36 ITA grafts were occluded at 0.78, 1.8, and 9.4 y (too few to model). SVG patency was 52% and 37% at 1 and 2 y, respectively. CONCLUSIONS: Among patients on dialysis who underwent CABG, coronary angiography for ischemic symptoms in a select subset revealed that SVG patency was lower than expected from published reports in the general CABG population and may contribute to the poor prognosis of this cohort. Further work is needed to guide graft selection and improve graft patency in dialysis patients.

PURPOSE OF REVIEW: Current results of lung transplantation still lag behind those of other solid-organ transplants. Although bronchial dehiscence was the main cause of early mortality in the past, modern-day operative techniques and immunosuppression regiments have decreased, but not eliminated, this complication. Current barriers to long-term survival are chronic lung allograft dysfunction and infection. Bronchial artery revascularization was effective in decreasing bronchial anastomotic complications, but it was largely abandoned because of technical challenges. RECENT FINDINGS: Long-term follow-up in patients with bronchial artery revascularization has shown a survival advantage compared with the standard lung transplant technique. Recent data also show decreased infection, decreased early rejection and decreased bronchiolitis obliterans syndrome, in addition to confirming the known advantages in bronchial healing. Modifications of the technique have also made bronchial artery revascularization feasible in the pediatric population. SUMMARY: Bronchial artery revascularization, although initially designed for bronchial healing, has clinical advantages that extend long term, including survival, infection and decreased graft dysfunction. Its usage in lung transplantation needs to be revisited.

PURPOSE: To compare dual-energy computed tomography (DECT) based qualitative and quantitative parameters in chronic thromboembolic pulmonary hypertension with various postoperative primary and secondary endpoints. MATERIALS AND METHODS: This was a retrospective analysis of 64 patients with chronic thromboembolic pulmonary hypertension who underwent DECT. First, a clot score was calculated by assigning the following score: pulmonary trunk-5, each main pulmonary artery-4, each lobar-3, each segmental-2, and subsegmental-1 per lobe; the sum total was then calculated. The perfusion defect (PD) score was calculated by assigning 1 point to each segmental PD. The combined score was calculated by adding clot and PD scores. For quantitative evaluation, we calculated perfused blood volume (PBV) (%) of each lung and the sum of both lungs. Primary endpoints included testing association between combined score and total PBV with change in mean pulmonary arterial pressure ([mPAP], change calculated as preop minus postop values). Secondary endpoints included explorative analysis of the correlation between combined score and PBV with change in preoperative and postoperative pulmonary vascular resistance, change in preoperative 6-minute walk distance (6MWD), and immediate postoperative complications such as reperfusion edema, ECMO placement, stroke, death and mechanical ventilation for more than 48 hours, all within 1 month of surgery. RESULTS: Higher combined scores were associated with larger decreases in mPAP ( =0.27, P =0.036). On average, the decrease in mPAP (pre mPAP-post mPAP) increased by 2.2 mm Hg (95% CI: -0.6, 5.0) with each 10 unit increase in combined score. The correlation between total PBV and change in mPAP was small and not statistically significant. During an exploratory analysis, higher combined scores were associated with larger increases in 6MWD at 6 months postprocedure ( =0.55, P =0.002). CONCLUSION: Calculation of DECT-based combined score offers potential in the evaluation of hemodynamic response to surgery. This response can also be objectively quantified.
RESUMEN
OBJECTIVES: To identify preoperative predictors of postcardiotomy cardiogenic shock in patients with ischemic and nonischemic cardiomyopathy and evaluate trajectory of postoperative ventricular function. METHODS: From January 2017 to January 2020, 238 patients with ejection fraction <30% (206/238) or 30% to 34% with at least moderately severe mitral regurgitation (32/238) underwent conventional cardiac surgery at Cleveland Clinic, 125 with ischemic and 113 with nonischemic cardiomyopathy. Preoperative ejection fraction was 25 ± 4.5%. The primary outcome was postcardiotomy cardiogenic shock, defined as need for microaxial temporary left ventricular assist device, extracorporeal membrane oxygenation, or vasoactive-inotropic score >25. RandomForestSRC was used to identify its predictors. RESULTS: Postcardiotomy cardiogenic shock occurred in 27% (65/238). Pulmonary artery pulsatility index <3.5 and pulmonary capillary wedge pressure >19 mm Hg were the most important factors predictive of postcardiotomy cardiogenic shock in ischemic cardiomyopathy. Cardiac index <2.2 L·min-1 m-2 and pulmonary capillary wedge pressure >21 mm Hg were the most important predictive factors in nonischemic cardiomyopathy. Operative mortality was 1.7%. Ejection fraction at 12 months after surgery increased to 39% (confidence interval, 35-40%) in the ischemic group and 37% (confidence interval, 35-38%) in the nonischemic cardiomyopathy group. CONCLUSIONS: Predictors of postcardiotomy cardiogenic shock were different in ischemic and nonischemic cardiomyopathy. Right heart dysfunction, indicated by low pulmonary artery pulsatility index, was the most important predictor in ischemic cardiomyopathy, whereas greater degree of cardiac decompensation was the most important in nonischemic cardiomyopathy. Therefore, preoperative right heart catheterization will help identify patients with low ejection fraction who are at greater risk of postcardiotomy cardiogenic shock.
RESUMEN
Background: The Ozaki procedure using autologous pericardium is an interesting but complex alternative for aortic valve replacement. We present a standardized approach to minimize the learning curve and confirm reproducibility. Methods: After careful preparation, from May 2015 to February 2021, an Ozaki procedure was performed on 46 patients age 51 ± 14 years. Seven had unicuspid (15%), 29 bicuspid (63%), and 10 tricuspid (22%) aortic valves, and 2 patients had endocarditis. Endpoints were operative learning curves, perioperative outcomes, intermediate-term valve hemodynamics, reintervention, health-related quality of life (MacNew Heart Disease Health-Related Quality of Life questionnaire), and mortality. Results: Cardiopulmonary bypass and aortic clamp times decreased from 145 to 125 âminutes and 120 to 100 âminutes, respectively, over the first 20 cases, reflecting the learning curve. There was no major perioperative morbidity or mortality. Median postoperative stay was 6.9 days. Aortic regurgitation was mild or less in all but 2 patients who developed moderate aortic regurgitation. Mean aortic valve gradient was 7.9 mmHg postoperatively, 9.2 mmHg by 6 months, and constant thereafter. Left ventricular ejection fraction was 58% preoperatively, 60% at 6 months, and remained stable thereafter. One patient developed infective endocarditis 7 months postoperatively, failed medical management, and underwent valve replacement at 14 months. Two-year survival was 96%, with 1 noncardiac death at 16 months. Health-related quality of life in mental, physical, and emotional domains was better than matched norms, global 6.2 vs. 5.0 (p < 0.0001). Conclusions: Using a well-prepared standardized approach, the Ozaki procedure is reproducible with a short learning curve, excellent hemodynamic performance, and good quality of life.
RESUMEN
Remarkable advances have occurred in the understanding of the pathophysiology of pericardial diseases and the role of multimodality imaging in this field. Medical therapy and surgical options for pericardial diseases have also evolved substantially. Pericardiectomy is indicated for chronic or irreversible constrictive pericarditis, refractory recurrent pericarditis despite optimal medical therapy, or partial agenesis of the pericardium with a complication (eg, herniation). A multidisciplinary evaluation before pericardiectomy is essential for optimal patient outcomes. Overall, given the good outcomes reported, radical pericardiectomy on cardiopulmonary bypass, if feasible, is the preferred approach. Due to patient complexity, as well as the technical aspects of the surgery, pericardiectomy should be performed at high-volume centers that have the required expertise. The current review highlights the essential features of this multidisciplinary approach from diagnosis to recovery in patients undergoing pericardiectomy.

A persistent left superior vena cava (PLSVC) is a congenital anomaly wherein the left superior cardinal vein fails to regress. We describe the case of a successful orthotopic heart transplant using a donor heart with a PLSVC and congenital absence of a right superior vena cava (SVC) in a recipient with normal anatomy. After donor cardiectomy, the donor organ's PLSVC was ligated near the insertion site into the coronary sinus. The recipient underwent cardiectomy such that the native SVC was left with a long right atrial cuff. A modified bicaval technique was used to anastomose the recipient's right atrial cuff directly to the donor's right atrial appendage. This technique restored the recipient's normal anatomy, and we demonstrated that donor hearts with a PLSVC and absent right SVC might be used for transplant. Without other disqualifying abnormalities, surgeons should consider accepting these organs for life-saving transplant operations.

Spontaneous coronary artery dissection is an uncommon cause of myocardial ischemia. Conservative management is the mainstay, although a few patients will require revascularization. We present a case of a 31-year-old woman whose extensive dissection necessitated coronary artery bypass grafting requiring an extended arteriotomy for excision of the thrombus and dissection flap. (Level of Difficulty: Advanced.).
RESUMEN
Patients with durable left ventricular assist devices (LVAD) that develop central device infections can prove prohibitively challenging to treat and may require device explant for source control. In bridge to transplant (BTT) LVAD patients, the management of mediastinal infection is further complicated by changes in the 2018 United Network of Organ Sharing (UNOS) allocation system, which resulted in a comparatively lower listing status than in its previous iteration. We present the case of a 36-year-old male with nonischemic cardiomyopathy status post Heartmate 3 (HM3) implantation as BTT who after a year of stable HM3 support, developed a severe bacterial infection along the outflow graft. Despite attempts at finding a suitable donor at his current listing, his clinical status continued to deteriorate. To obtain infection source control, he underwent LVAD explant and insertion of a left axillary artery Impella 5.5 ventricular assist device for necessary hemodynamic support. The patient's listing was upgraded to Status 2, and following the identification of a suitable donor, underwent successful heart transplantation. This case highlights the limitation of the updated UNOS heart allocation system for patients with central device infections and describes the successful use of salvage temporary mechanical circulatory support to bridge to transplantation.

Objectives: The aim of this study was to explore the associations between percutaneous ventricular assist device (pVAD) insertion timing relative to cardiac surgery and patient outcomes. Methods: The Nationwide Inpatient Sample was queried for patients undergoing cardiac surgery and pVAD insertion in the same admission from 2016 to 2019. Patients were stratified by timing of pVAD insertion. Preoperative characteristics, postoperative complications, and mortality were compared among groups. Results: Overall, 3695 patients underwent cardiac surgery and pVAD insertion during the same hospitalization (pre: 1130, intra: 1690, and post: 875). The distribution of cardiac surgery procedures was similar across groups. Median Elixhauser Comorbidity Index was 13 for pre-, 15 for intra-, and 17 for postoperative pVAD patients (P = .021). Patients who received a postoperative pVAD were associated with increased mortality (pre: 18%, intra: 39%, and post: 54%; P < .01). Increased complication rates were also associated with postoperative pVAD insertion (pre: 61%, intra: 55%, and post: 75%; P < .01). Preoperative pVAD insertion was associated with increase rates of sepsis (pre: 18%, intra: 9.8%, and post: 17%; P = .01) and pneumonia (pre: 38%, intra: 23%, and post: 31%; P < .01). Postoperative pVAD insertion was associated with increased rates of gastrointestinal bleeding (pre: 2.2%, intra: 3.0%, and post: 7.4%; P = .01), renal failure (pre: 10%, intra: 9.2%, and post: 17%; P = .01), and prolonged ventilation (pre: 44%, intra: 41%, and post: 54%; P = .02). Conclusions: Postoperative pVAD insertion following cardiac surgery was associated with increased complications and mortality compared with preoperative or intraoperative insertion. Further studies should explore optimal utilization and timing of pVAD insertion in patients undergoing cardiac surgery.
RESUMEN
OBJECTIVE: Left ventricular assist devices require a psychosocial assessment to determine candidacy despite limited data correlating with outcome. Our objective is to determine whether the Stanford Integrated Psychosocial Assessment for Transplant, a tool validated for transplant and widely used by left ventricular assist device programs, predicts left ventricular assist device program hospital readmissions and death. METHODS: We performed a retrospective analysis of adults at the Cleveland Clinic with Stanford Integrated Psychosocial Assessment for Transplant scores before primary left ventricular assist device program implantation from April 1, 2013, to December 31, 2018. The primary outcome was unplanned hospital readmissions censored at death, transplantation, and transfer of care. The secondary outcome was death. RESULTS: There were 263 patients in the left ventricular assist device program with a median (Q1, Q3) Stanford Integrated Psychosocial Assessment for Transplant score of 16 (8, 28). During a median follow-up 1.2 years, 56 died, 65 underwent transplantation, and 21 had transferred care. There were 640 unplanned hospital readmissions among 250 patients with at least 1 outpatient visit at our center. In a multivariable analysis, Stanford Integrated Psychosocial Assessment for Transplant components but not total Stanford Integrated Psychosocial Assessment for Transplant score was associated with readmissions. Psychopathology (Stanford Integrated Psychosocial Assessment for Transplant C-IX) was associated with hemocompatibility (coefficient 0.21 ± standard error 0.11, P = .040) and cardiac (0.15 ± 0.065, P = .02) readmissions. Patient readiness was associated with noncardiac (Stanford Integrated Psychosocial Assessment for Transplant A-III, 0.24 ± 0.099, P = .016) and cardiac (Stanford Integrated Psychosocial Assessment for Transplant A-low total, 0.037 ± 0.014, P = .007) readmissions. Poor living environment (Stanford Integrated Psychosocial Assessment for Transplant B-VIII) was associated with device-related readmissions (0.83 ± 0.34, P = .014). Death was associated with organic psychopathology or neurocognitive impairment (Stanford Integrated Psychosocial Assessment for Transplant C-X, 0.59 ± 0.21, P = .006). CONCLUSIONS: Total Stanford Integrated Psychosocial Assessment for Transplant score was not associated with left ventricular assist device program readmission or mortality. However, we identified certain Stanford Integrated Psychosocial Assessment for Transplant components that were associated with outcome and could be used to create a left ventricular assist device program specific psychosocial tool.

OBJECTIVE: Patient characteristics, risks, and outcomes associated with reoperative multivalve cardiac surgery are poorly characterized. Effect of patient variables and surgical components of each reoperation were evaluated with regard to operative mortality. METHODS: From January 2008 to January 2022, 2324 patients with previous cardiac surgery underwent 2352 reoperations involving repair or replacement of multiple cardiac valves at Cleveland Clinic. Mean age was 66 ± 14 years. Number of surgical components representing surgical complexity (valve procedures, aortic surgery, coronary artery bypass grafting, and atrial fibrillation procedures) ranged from 2 to 6. Random forest for imbalanced data was used to identify risk factors for operative mortality. RESULTS: Surgery was elective in 1327 (56%), urgent in 1006 (43%), and emergency in 19 (0.8%). First-time reoperations were performed in 1796 (76%) and 556 (24%) had 2 or more previous operations. Isolated multivalve operations comprised 54% (1265) of cases; 1087 incorporated additional surgical components. Two valves were operated on in 80% (1889) of cases, 3 in 20% (461), and 4 in 0.09% (2). Operative mortality was 4.2% (98 out of 2352), with 1.7% (12 out of 704) for elective, isolated multivalve reoperations. For each added surgical component, operative mortality incrementally increased, from 2.4% for 2 components (24 out of 1009) to 17% for ≥5 (5 out of 30). Predictors of operative mortality included coronary artery bypass grafting, surgical urgency, cardiac, renal dysfunction, peripheral artery disease, New York Heart Association functional class, and anemia. CONCLUSIONS: Elective, isolated reoperative multivalve surgery can be performed with low mortality. Surgical complexity coupled with key physiologic factors can be used to inform surgical risk and decision making.
RESUMEN
A 24-year-old man presented with a nonischemic cardiomyopathy of unknown etiology, apical aneurysm, and a secondary mitral regurgitation. Computer tomography-derived 3-dimensional model of the patient's heart was an essential step in guiding the surgical management for an optimal outcome. (Level of Difficulty: Advanced.).
