RESUMEN

BACKGROUND: With increasing importance, health-related quality of life (HRQoL) has become a crucial outcome measure of cardiac surgery. The aim of this study was to assess the dynamics of HRQoL change within 12 months after surgery and to identify predictors of deterioration in physical and mental health. METHODS: The cohort of this prospective study included 164 consecutive patients who underwent elective surgery. HRQoL was assessed on the basis of the Short-Form 36 questionnaire at three different times: upon admission and at 3 and 12 months after surgery. The minimal clinically important difference (MCID) was used to determine whether the surgery resulted in deterioration of HRQoL. RESULTS: In general, physical and mental health status improved within the first year after cardiac surgery. However, after 12 months, 7.9 and 21.2% of patients had clinically significant poorer physical (PCS) and mental component summary (MCS) scores, based on the MCID approach. The results of multivariate analysis identified preoperative health status, age < 70 years, coronary artery bypass grafting, and a previous neurological event as predictors of deterioration in postoperative HRQoL. The greatest risks for deterioration were higher preoperative PCS and MCS scores. CONCLUSION: Although we were able to demonstrate a general improvement in the HRQoL following cardiac surgery, in one-fifth of patients, there was no recovery of mental health status even after 1 year. As this effect is mainly determined by preoperative functional status, HRQoL should be an integral part of medical consultation, especially in younger patients with a positive perception of quality of life.

RESUMEN

BACKGROUND: We analyzed the short-term and mid-term outcomes as well as the health-related quality of life (HRQOL) of octogenarians undergoing elective and urgent cardiac surgery. PATIENTS AND METHODS: We retrospectively identified 688 consecutive octogenarians who underwent cardiac surgery at our center between January 2012 and December 2019. A propensity score matching was performed which resulted in the formation of 80 matched pairs. The patients were interviewed and the Short Form-36 survey was used to assess the HRQOL of survivors. Multivariable analysis incorporated binary logistic regression using a forward stepwise (conditional) model. RESULTS: The median age of the matched cohort was 82 years (p = 0.937), among whom, 38.8% of patients were female (p = 0.196). The median EuroSCORE II of the matched cohort was 19.4% (10.1-39.1%). The duration of postoperative mechanical ventilation was found to be independently associated with in-hospital mortality (odds ratio: 1.01 [95% confidence interval: 1.0-1.02], p = 0.038). The survival rates at 1, 2, and 5 years was 75.0, 72.0, and 46.0%, respectively. There was no difference in the total survival between the groups (p = 0.080). The physical health summary score was 41 (30-51) for the elective patients and 42 (35-49) for the nonelective octogenarians (p = 0.581). The median mental health summary scores were 56 (48-60) and 58 (52-60), respectively (p = 0.351). CONCLUSION: Cardiac surgery can be performed in octogenarians with good results and survivors enjoy a good quality of life; however, the indication for surgery or especially for escalation of therapy should always be made prudently, reserved, and in consideration of patient expectations.

RESUMEN

INTRODUCTION: Mitral valve surgery has developed into a strong subspecialty of cardiac surgery with operative techniques and outcomes constantly improving. The development of bradyarrhythmias after mitral valve surgery is not completely understood. METHODS: We investigated a cohort of 797 patients requiring mitral valve surgery with and without concomitant procedures. Incidences and predictors of pacemaker requirement as well as survival were analyzed. RESULTS: In the complete follow-up period (median follow-up time: 6.09 years [95% confidence interval [CI]: 5.94-6.22 years, maximum 8.77 years) 80 patients (10% of the complete cohort) required pacemaker implantation for bradyarrhythmia. The cumulative rate of pacemaker implantation was 6.4% at 50 days (48 patients) with most (54.2%) requiring pacing for atrioventricular block. Mitral valve replacement (odds ratio [OR]: 1.905; 95% CI: 1.206-3.536; p = .041) and tricuspid ring annuloplasty (OR: 2.348; 95% CI: 1.165-4.730, p = .017) were identified as operative risk factors of pacemaker requirement after mitral valve surgery. Insulin-dependent diabetes mellitus was also identified as a predictor of pacemaker requirement (OR: 4.665; 95% CI: 1.975-11.02; p = .001). There was no difference in survival in the paced and unpaced groups. CONCLUSIONS: After mitral valve surgery, a relevant subgroup of patients requires pacemaker implantation-most for atrioventricular block. We identified mitral valve replacement and tricuspid ring annuloplasty as significant operative risk factors and insulin-dependent diabetes mellitus as a demographic risk factor. While anatomic relationships help explain the operative risk factors the role of diabetes mellitus is not completely understood.

RESUMEN

Tricuspid valve (TV) surgery is associated with a high risk of postoperative pacemaker requirement. We set out to identify the incidence of atrioventricular block (AVB) after TV surgery and determine whether atrioventricular conduction recovers within time.We investigated pre/intra- and postoperative predictors of AVB in patients who underwent tricuspid valve surgery (not only isolated TV surgery) at our institution between 2004 and 2017. Patients who had pacemakers prior to surgery were excluded.One year after surgery, 5.8% of the surviving cohort had received a pacemaker due to AVB. In the complete follow-up time, 33 out of 505 patients required pacemaker implantation because of AVB. Of the 37 patients who presented to the intensive care unit postoperatively with AVB III, 14 (38%) underwent pacemaker implantation for AVB, and 20 (54%) did not require a pacemaker. AVB III at ICU admission was identified as a predictor of pacemaker implantation (OR: 9.7, CI: 3.8-24.5, P < 0.001). TV endocarditis was also identified as a predictor (OR: 12.4, CI: 3.3-46.3, P < 0.001). Eleven out of 32 patients (34%) with tricuspid endocarditis required a pacemaker for AVB. The mean ventricular pacing burden within the first 5 years after pacemaker implantation was 79%.The issue of AVB after TV surgery is significant. Both the initial rhythm after surgery and etiology of the tricuspid disease can help predict pacemaker requirement. Within the first 5 years after surgery, the ventricular pacing burden remains high without relevant rhythm recovery.

RESUMEN

INTRODUCTION: Cardiac implantable electronic device (CIED) infections are associated with a high mortality. Our aim was to identify key predictors of survival in patients with CIED infections as to be able to detect high-risk patients and possibly affect modifiable factors. METHODS AND RESULTS: In this observational study, we collected data from 277 patients with CIED infections treated in our department between 2001 and 2017; predictors of survival were evaluated. The median time since the last CIED procedure was 0.83 years (interquartile range [IQR]: 0.25-3.01), median time since initial CIED implant was 4.79 years (IQR: 0.90-11.0 years). Survival at 30 days was 94.9% (95% confidence interval [CI]: 92.3-97.5) and survival at 1 year was 80.9% (CI: 76.4-85.7). Age (odds ratio [OR]: 1.05, CI: 1.01-1.09; P = .009), end stage renal disease (ESRD) with dialysis (OR: 5.14, CI: 1.87-14.11; P = .001), positive blood cultures (OR: 2.19, CI: 1.08-4.45; P = .030), and thrombocytopenia (OR: 2.3, CI, 1.03-5.15; P = .042) were identified as predictors of death within 1 year of treatment of CIED infection. CONCLUSION: Patients with CIED infection with prior ESRD with dialysis or preoperative thrombocytopenia are at an increased risk of 1-year mortality. We suggest that these patients be evaluated critically and resources be allocated to these patients more liberally. A greater understanding of the role of platelets in immunity may improve treatment of advanced infection in the future.

RESUMEN

OBJECTIVES: Cardiopulmonary bypass is associated with severe immune dysfunctions. Particularly, a cardiopulmonary bypass-related long-lasting immunosuppressive state predisposes patients to a higher risk of postoperative complications, such as persistent bacterial infections. This study was conducted to elucidate mechanisms of post-cardiopulmonary bypass immunosuppression. DESIGN: In vitro studies with human peripheral blood mononuclear cells. SETTING: Cardiosurgical ICU, University Research Laboratory. PATIENTS: Seventy-one patients undergoing cardiac surgery with cardiopulmonary bypass (enrolled May 2017 to August 2018). INTERVENTIONS: Peripheral blood mononuclear cells before and after cardiopulmonary bypass were analyzed for the expression of immunomodulatory cell markers by real-time quantitative reverse transcription polymerase chain reaction. T cell effector functions were determined by enzyme-linked immunosorbent assay, carboxyfluorescein succinimidyl ester staining, and cytotoxicity assays. Expression of cell surface markers was assessed by flow cytometry. CD15 cells were depleted by microbead separation. Serum arginine was measured by mass spectrometry. Patient peripheral blood mononuclear cells were incubated in different arginine concentrations, and T cell functions were tested. MEASUREMENTS AND MAIN RESULTS: After cardiopulmonary bypass, peripheral blood mononuclear cells exhibited significantly reduced levels of costimulatory receptors (inducible T-cell costimulator, interleukin 7 receptor), whereas inhibitory receptors (programmed cell death protein 1 and programmed cell death 1 ligand 1) were induced. T cell effector functions (interferon γ secretion, proliferation, and CD8-specific cell lysis) were markedly repressed. In 66 of 71 patients, a not yet described cell population was found, which could be characterized as myeloid-derived suppressor cells. Myeloid-derived suppressor cells are known to impair immune cell functions by expression of the arginine-degrading enzyme arginase-1. Accordingly, we found dramatically increased arginase-1 levels in post-cardiopulmonary bypass peripheral blood mononuclear cells, whereas serum arginine levels were significantly reduced. Depletion of myeloid-derived suppressor cells from post-cardiopulmonary bypass peripheral blood mononuclear cells remarkably improved T cell effector function in vitro. Additionally, in vitro supplementation of arginine enhanced T cell immunocompetence. CONCLUSIONS: Cardiopulmonary bypass strongly impairs the adaptive immune system by triggering the accumulation of myeloid-derived suppressor cells. These myeloid-derived suppressor cells induce an immunosuppressive T cell phenotype by increasing serum arginine breakdown. Supplementation with L-arginine may be an effective measure to counteract the onset of immunoparalysis in the setting of cardiopulmonary bypass.

RESUMEN

It is unknown how many pacemaker and implantable cardioverter defibrillator (ICD) leads perforate during lead placement. Symptoms of a perforated lead include shortness of breath and chest pain. Signs of perforation can include a high pacing threshold, reduced lead sensing, and a high lead impedance. We present the case of a patient where perforation of the single coil right ventricular lead was not evident in imaging but incidentally detected during operative aortic valve replacement. The lead perforation rate during device implantation is around 1%-ICD leads have a higher perforation rate.

RESUMEN

AIMS: The tricuspid valve is situated in close proximity to cardiac conduction tissue and damage to this tissue can affect postoperative rhythm. The aim of this study was to quantify the incidence of pacemaker requirement after tricuspid valve surgery and investigate predictors. METHODS: Data were collected via our operative data collection system and patient files. All patients who underwent surgical procedures of the tricuspid valve from 2004 until 2017 and lacked a pacemaker preoperatively were included in the study. RESULTS: In our cohort of 505 patients 54 required a pacemaker in the first 50 days after surgery. We calculated a 17.5% (95% confidence interval [CI], 13.5-21.3) risk of pacemaker implantation at 4 years postoperatively. Multivariate analysis identified preoperative active endocarditis (odds ratio 3.17; CI, 1.32-7.65; P = 0.010) and "inadequate pacemaker dependent rhythm" (defined as any intrinsic heart rate below 45 per minute requiring pacing) upon admission to the intensive care unit after surgery (odds ratio 5.924; CI, 2.82-12.44; P = 0.001) as predictors for pacemaker requirement in the first 50 days after surgery. Twenty-six pacemakers (48%) were implanted for atrioventricular block, 16 (30%) for sinus node dysfunction and 12 (22%) for atrial fibrillation. Kaplan-Meier analysis showed no difference in survival between the pacemaker and no pacemaker group. CONCLUSION: Surgery of the tricuspid valve has a high burden of postoperative pacemaker requirement. Preoperative active endocarditis and the initial postoperative rhythm are predictors. Understanding this allows for better decision-making regarding further medical/device therapy.

RESUMEN

INTRODUCTION: We investigated the development of sinus node dysfunction (SND) requiring pacemaker implantation after heart transplant (HTx) especially regarding pacing burden in these patients. PATIENTS AND METHODS: Patients requiring a pacemaker for SND were compared to all other patients in an HTx cohort including transplant patients from 1981 to 2016. RESULTS: Sinus node dysfunction requiring pacemaker implantation developed in 118 patients (10%). These patients had received a biatrial anastomosis more frequently than those in the No SND group 95.8% vs 90.0% (P = .042). The ratio of reperfusion time to aortic cross-clamp time was significantly smaller in the SND group compared to the No SND group 71.7% vs 80.3% (P = .033). This also holds for the ratio of reperfusion time to ischemia time, which was 23.2% and 28.6%, respectively (P = .032). Pacing burden decreased from 90.5% to 66.3% after 2 years and remained around this value in the remaining 4 years of follow-up. CONCLUSION: We identified the biatrial anastomosis and a low ratio of reperfusion time to aortic cross-clamp time as well as to ischemia time as risk factors for SND requiring pacing. After implantation pacemakers continue to pace for over 60% of the time after 6 years.

RESUMEN

BACKGROUND: In an attempt to improve pacemaker therapy after pediatric transplantation, we investigated risk factors, indication for pacing, and pacing burden after pediatric heart transplantation. METHODS AND RESULTS: In this retrospective study, 139 pediatric heart transplant recipients, of whom 122 did not and 17 did require pacemakers, were investigated. Eleven of the 17 patients requiring a permanent pacemaker (PPM) received their heart from a female donor (68.8%); this compares to 48 of 122 patients (43.2%, P  =  0.082) in the group not requiring a pacemaker (No PPM). The donor age and height were significantly greater in the PPM group at a median of 25.26 years (16.29-48.00) and 160 cm (153-170) compared with 11.96 years (1.73-19.95) and 141 cm (89-165) in the No PPM group (P  =  0.003 and 0.015, respectively). Of the 17 patients requiring pacemakers, 13 presented with sinus node dysfunction (SND) and four with atrioventricular block. The atrial pacing burden in patients with SND remained above 60% within the 5 years of follow-up investigated. There was no significant difference in mortality between those patients requiring a PPM and those not (Log-Rank test: P  =  0.672). CONCLUSION: We found that in our cohort donor characteristics were key risk factors for pacemaker implantation in transplanted children. The data suggest that when patients require a pacemaker in posttransplant SND, they will require a relevant amount of pacing for at least 5 years. The pacing burden after this point remains to be investigated. Mortality does not differ between pediatric heart transplant patients with and without pacemakers.

RESUMEN

BACKGROUND: After around 10% of heart transplant patients require pacemaker implantation. The bradyarrhythmias causing pacemaker requirement include sinus node dysfunction (SND) and atrioventricular block (AVB). This study sought to define clinical predictors for pacemaker requirement as well as identify differences in the patient groups developing SND and AVB. METHODS: Our operative database was used to collect retrospective recipient, donor, and operative data of all patients receiving orthotopic heart transplants between 1981 and 2016. RESULTS: In the 35-year period 1,179 transplants were performed (mean recipient age 45.5 ± 0.5 years, 20.4% female, 90.6% biatrial technique) with bradyarrhythmias requiring pacemaker implantation developing in 135 patients (11.5%). Independent risk factors were prolonged operative time 340 minutes versus 313 minutes (P = 0.027) and a biatrial anastomosis (P = 0.036). Ischemia time, cardiopulmonary bypass time, aortic cross clamp time, and reperfusion time all had no significant effect on pacemaker implantation rates. Similarly, whether the transplant was a reoperation, a retransplant, or performed after primary assist implantation had no effects on pacemaker implantation rates. There was no survival difference between the paced and nonpaced groups. The donor age was higher in the patients who developed AVB as the indication for pacemaker implantation (43 vs 34 years, P = 0.031). Patients with AVB had longer aortic cross clamp times and developed the arrhythmia later than those who developed SND. CONCLUSIONS: Use of the bicaval instead of the biatrial technique and shortened operative times should reduce pacemaker requirement after heart transplantation. Survival is not affected by this complication.

RESUMEN

PURPOSE: The HEARTSTRING Proximal Seal System is used to avoid aortic clamping to insert the intraaortic balloon pump (IABP) in the ascending aorta or the aortic arch. This technique is used when calcification or atheroma prevents side clamping of the ascending aorta or the aortic arch. DESCRIPTION: A vein graft or a small-caliber vascular prosthesis for the later insertion of the IABP is sewn to the ascending aorta or the aortic arch using the HEARTSTRING Proximal Seal System. EVALUATION: In our department, this technique is applied whenever insertion of the IABP is not feasible via the femoral arteries.  CONCLUSION: The technique allows the safe insertion of the IABP via the ascending aorta or the aortic arch.

RESUMEN

Importance: New-onset postoperative atrial fibrillation (POAF) occurs in approximately 30% of patients undergoing coronary artery bypass grafting (CABG). It is unknown whether early recurrence is associated with worse outcomes. Objective: To test the hypothesis that early AF recurrence in patients with POAF after CABG is associated with worse outcomes. Design, Setting, and Participants: This Swedish nationwide cohort study used prospectively collected data from the SWEDEHEART (Swedish Web System for Enhancement and Development of Evidence-Based Care in Heart Disease Evaluated According to Recommended Therapies) registry and 3 other mandatory national registries. The study included patients who underwent isolated first-time CABG between January 1, 2007, and December 31, 2020, and developed POAF. Data analysis was performed between March 6 and September 16, 2023. Exposure: Early AF recurrence defined as an episode of AF leading to hospital care within 3 months after discharge. Main Outcomes and Measures: The primary outcome was all-cause mortality. Secondary outcomes included ischemic stroke, any thromboembolism, heart failure hospitalization, and major bleeding within 2 years after discharge. The groups were compared with multivariable Cox regression models, with early AF recurrence as a time-dependent covariate. The hypothesis tested was formulated after data collection. Results: Of the 35 329 patients identified, 10 609 (30.0%) developed POAF after CABG and were included in this study. Their median age was 71 (IQR, 66-76) years. The median follow-up was 7.1 (IQR, 2.9-9.0) years, and most patients (81.6%) were men. Early AF recurrence occurred in 6.7% of patients. Event rates (95% CIs) per 100 patient-years with vs without early AF recurrence were 2.21 (1.49-3.24) vs 2.03 (1.83-2.25) for all-cause mortality, 3.94 (2.92-5.28) vs 2.79 (2.56-3.05) for heart failure hospitalization, and 3.97 (2.95-5.30) vs 2.74 (2.51-2.99) for major bleeding. No association between early AF recurrence and all-cause mortality was observed (adjusted hazard ratio [AHR], 1.17 [95% CI, 0.80-1.74]; P = .41). In exploratory analyses, there was an association with heart failure hospitalization (AHR, 1.80 [95% CI, 1.32-2.45]; P = .001) and major bleeding (AHR, 1.92 [1.42-2.61]; P < .001). Conclusions and Relevance: In this cohort study of early AF recurrence after POAF in patients who underwent CABG, no association was found between early AF recurrence and all-cause mortality. Exploratory analyses showed associations between AF recurrence and heart failure hospitalization, oral anticoagulation, and major bleeding.

RESUMEN

Background: Extracorporeal life support (ECLS) therapy for refractory postcardiotomy cardiogenic shock (rPCS) is associated with high early mortality rates. This study aimed to identify negative predictors of mid-term survival and to assess health-related quality of life (HRQoL) and recovery of the survivors. Methods: Between 2017 and 2020, 142 consecutive patients received ECLS therapy following cardiac surgery. The median age was 66.0 [57.0-73.0] years, 67.6% were male and the median EuroSCORE II was 10.5% [4.2-21.3]. In 48 patients, HRQoL was examined using the 36-Item Short Form Survey (SF-36) and the modified Rankin-Scale (mRS) at a median follow-up time of 2.2 [1.9-3.2] years. Results: Estimated survival rates at 3, 12, 24 and 36 months were 47%, 46%, 43% and 43% (SE: 4%). Multivariable Cox Proportional Hazard regression analysis revealed preoperative EuroSCORE II (p = 0.013), impaired renal function (p = 0.010), cardiopulmonary bypass duration (p = 0.015) and pre-ECLS lactate levels (p = 0.004) as independent predictors of mid-term mortality. At the time of follow-up, 83.3% of the survivors were free of moderate to severe disability (mRS < 3). SF-36 analysis showed a physical component summary of 45.5 ± 10.2 and a mental component summary of 50.6 ± 12.5. Conclusions: Considering the disease to be treated, ECLS for rPCS is associated with acceptable mid-term survival, health-related quality of life and functional status. Preoperative EuroSCORE II, impaired renal function, cardiopulmonary bypass duration and lactate levels prior to ECLS implantation were identified as negative predictors and should be included in the decision-making process.

RESUMEN

The wall of myocardial terminal vessels, consisting of a continuous endothelial tube with an adventitial coat of pericytes in their extracellular matrix, constitutes a remarkably tight barrier to solute transport between the blood and the parenchyma. This constructional principle of precapillary arterioles, capillaries and postcapillary venules extends both up- and downstream into the arterial and venous limbs, where the original microvessel tube widens and becomes the innermost layer-the intima-of all the larger coronary vessels. In the myocardium's smallest functional units and in the intima of the coronaries, the pericytes play key roles by virtue of both their central histological localization and their physiological functions. Recognition and integration of these properties has led to new pathogenetic models for diverse heart diseases and suggests that current therapeutic concepts need to be revised.

RESUMEN

A 65-year-old male patient was considered inoperable by conventional means for a previous triple coronary artery bypass grafting with a patent in situ right internal mammary artery graft to the left anterior descending artery crossing the thorax at midline directly behind the sternum. Transcatheter aortic valve implantation failed due to loss of the prosthetic device in the left ventricular outflow tract. Mandatory conversion was accomplished by an inferior partial T-shape sternotomy and extracorporeal circulation draining from the right atrium and feeding into the right femoral artery. A conventional 27-mm aortic valve bioprosthesis was successfully implanted during deep hypothermic circulatory arrest. The patient recovered normally exhibiting no neurological or cardiocirculatory complications.

RESUMEN

BACKGROUND: The management of type A intramural hematoma (IMH) is controversial. Although most Western countries still recommend immediate surgical repair, some centers in Asia have shown good results recently with medical treatment alone. Here, we present a case of type A IMH which was discovered during the operation to be a thrombosed type A dissection. CASE REPORT: An 83-year-old female patient presented with acute chest pain. After diagnostic exclusion of myocardial infarction, computed tomography was performed, which showed an IMH from the ascending to the descending aorta. No intimal flap could be detected. The ascending aorta was replaced surgically with a prosthesis. During the operation, we found a ruptured intimal plaque, which had caused dissection of the aorta with thrombosis of the false lumen. The true diagnosis-thrombosed type A dissection and not IMH-was revealed neither by computed tomography nor by transesophageal echocardiography. CONCLUSION: Type A IMH should still be treated with immediate surgical repair because in many cases it turns out to be thrombosed type A dissection.

RESUMEN

Repairing left ventricular aneurysms that form after myocardial infarction may be challenging, especially if located close to the important native coronary arteries. Here, we describe a rare case of anterolateral aneurysm of the basal LV wall and a safe, efficient approach for a patch plasty sparing the native left anterior descending.

RESUMEN

When using rapid deployment surgical aortic valve replacement (RD SAVR) in treating bicuspid aortic valve morphology (BAV), several challenges are faced due to annular asymmetry. The Sievers classification has been traditionally used for the description of BAV morphology. In this study, we aimed to conduct a retrospective feasibility analysis of RD SAVR in relation to the Sievers classification. From January 2014 to March 2022, 31 patients with BAV morphology (15 patients with Sievers type 0 BAV and 16 with Sievers type 1 BAV) underwent RD SAVR. Specific surgical techniques were applied depending on the BAV morphology. Comparable clinical outcomes were observed. No paravalvular leaks and no valvular re-interventions occurred in either group. CPB and cross-clamping times, as well as the prosthesis sizes used, were also not significantly different. Postoperative mean gradients were comparable in both groups. No significant distinction was found between the groups in terms of postoperative pacemaker indication, postoperative stroke, or death. Annular symmetry can be adequately restored through precise prosthesis sizing and placement according to an individual's valve morphology regardless of the Sievers classification of BAV by choosing a different landmark for the initial suture. RD SAVR seems to be a safe approach for any bicuspid morphology, with good hemodynamic results and time-saving potential in experienced hands.
