ObjectiveTo summarize the perioperative management strategies and early results of modified Morrow expanded operation and coronary artery bypass grafting (CABG) in patients with hypertrophic obstructive cardiomyopathy (HOCM) and coronary atherosclerotic heart disease.MethodsBetween January 2012 and December 2017, in the Second Inpatient Department of Fuwai Hospital, 32 patients (20 females and 12 males) underwent modified expanded Morrow operation and CABG. The median age was 53.7±8.7 years (interquartile range 37 to 67 years). Preoperative chest distress symptom was found in 24 patients, chest pain symptom was found in 14 patients, history of syncope in 6 patients. Cardiac echocardiography, electrocardiogram, chest X-ray, magnectic resonance imaging (MRI) were performed routinely after operation and follow-up to analyze structure and function of heart and mitral valve.ResultsAll patients underwent modified and expanded Morrow combined with CABG. The preoperative left ventricular outflow tract peak pressure difference (LVOTG) was 40 to 152 (79.6±28.7) mm Hg. Four patients underwent myocardial bridge releasing in the same period, mitral valve replacement in 2 patients, mitral valve angioplasty in 3 patients, Maze operation in 2 patients and tricuspid valveoplasty in 3 patients. There was no hospital mortality. CABG surgery in patients with branches included anterior descending artery in 26 patients, diagonal branch in 16 patients, left circumflex in 8 patients, right coronary artery in 11 patients. There were 15 patients with one coronary artery (CA) bypass graft, 5 patients with two CA bypass grafts, and 12 patients with 3 CA bypass grafts. The average of CA bypass grafts was 1.9±0.6. The postoperative ICU time ranged from 1–13 (4.1±2.8) days and postoperative hospital stay ranged from 7 to 30 (12.6±5.5) days. No severe postoperative complications were found and 1 patient had postoperative incision healing. The postoperative new arrhythmia included left bundle branch block in 6 patients. Compared with the preoperative values, postoperative left ventricular outflow tract peak pressure (79.6±28.7 mm Hg vs. 10.8±5.9 mm Hg, P<0.001), interventricular septum thickness (1.9±0.4 cm vs. 1.3±0.5 cm, P<0.001) were decreased obviously. Mitral valve closure is good or only mild reflux, mitral valve forward movement (SAM sign) disappeared. The patients were followed up for 6-68 months, with an average of 38.8±20.6 months. All patients were followed up with symptoms disappeared or only mild symptoms. NYHA classification decreased Ⅰ to Ⅱ grade after surgery, without long-term mortality, complications or reoperation.ConclusionFor patients with hypertrophic obstructive cardiomyopathy with coronary atherosclerotic heart disease, the application of improved expand morrow operation at the same time undergoing coronary artery bypass grafting is safe. It can significantly improve patients' survival and reduce symptoms, play a synergistic effect, and do not increase the patient's surgical complications.
As technology advances, current evidence supports the use of devices for valvular heart disease interventions, including transcatheter aortic valve implantation, transcatheter mitral or tricuspid valve repair, and transcatheter mitral valve implantation. These procedures require antithrombotic therapy to prevent thromboembolic events during the perioperative period, and these therapies are associated with an increased risk of bleeding complications. To date, there are challenges and controversies regarding how to balance the risk of thrombosis and bleeding in these patients, and therefore the optimal antithrombotic regimen remains unclear. In this review, we summarize the current evidence for antithrombotic therapy after transcatheter intervention in patients with valvular heart disease and highlight the importance of an individualized approach in targeting these patients.
Objective To summarize our clinical experience of endovascular repair of aortic pseudoaneurysms，andexplore the etiology of the disease，treatment indications，and early and midterm results of the procedure. Methods From November 2009 to May 2012，52 patients with aortic pseudoaneurysms received endovascular aortic repair （EVAR） in FuWai Hospital. There were 44 male and 8 female patients with their age of （53.8±13.5 ） years. Their onset syndromes includedchest or back pain in 46 patients and hoarseness in 5 patients. There were 23 acute patients and 29 chronic patients. Aortic pseudoaneurysms located at the descending thoracic aorta in 51 patients and the abdominal aorta in 1 patient. The meandiameter of the aortic pseudoaneurysms was （45.1±33.8） mm. All the patients were diagnosed using enhanced CT scan of the aorta. Three patients received emergency EVAR. All the patients received EVAR through the femoral arteries under general anesthesia. Forty-six patients underwent isolated EVAR，5 patients received hybrid technique for EVAR via the neck，and 1 patient received hybrid technique including EVAR and total arch replacement via median sternotomy under normothermia. The average diameter of stent-grafts was （34.2±3.3） mm and the average length was （157.7±20.3） mm. Enhanced CT scan of the aorta was performed before discharge，3 months and 1 year after EVAR during follow-up. Results There was no in-hospital death and EVAR was 100% successful. All the patients （100%） were followed up for 1-31 （12.6±7.9）months after discharge. Their chest or back pain symptoms all significantly improved. Their hoarseness improved too duringfollow-up. One patient’s hoarseness disappeared early after EVAR but recurred 5 months after EVAR. Enhanced CT scan showed enlargement of the stent-graft without endoleak. One patient underwent emergency EVAR for sudden onset of massivehemoptysis，recovered well before discharge，and was readmitted to hospital 5 months after EVAR because of fetid sputum and hemoptysis，who was diagnosed as Behcet’s disease and cured after anti-infection and immunosuppressive therapy. One patient had recurrent fever before and 6 months after EVAR and was cured by antibiotic therapy. Intraoperative angiographyshowed trivial typeⅠendoleak in 4 patients right after stent-graft deployment，which disappeared in enhanced CT scan 3-6 months after EVAR. Intraoperative angiography showed no endoleak in all the other patients，and their enhanced CT scans 3 months and 1 year after EVAR showed complete sealing between the stent-grafts and the aortic wall，thrombus in the pseudoaneurysm sac and decreased diameters of the pseudoaneurysms without endoleak. Two patients had hemiplegia 1 dayand 6 days after EVAR respectively，1 patient was cured and discharged and the other patient survived with hemiplegicsequelae. One patient with an abdominal aortic pseudoaneurysm died of sudden onset of cerebral infarction at home 3 monthsafter EVAR. Conclusions Endovascular repair of descending aortic pseudoaneurysms is safe and effective with good early and midterm results，and longer follow-up is needed for its long-term outcomes. Individualized treatment plan is basedon the location of the pseudoaneurysms. Preoperative meticulous medical history and physical examination are both importantfor the differentiation of the etiology of aortic pseudoaneurysms. Postoperative treatment based on the etiology and close follow-up are also needed to ensure long-term results.
ObjectiveTo systematically evaluate the effects of non-vitamin K antagonist oral anticoagulants (NOAC) and vitamin K antagonists (VKA) on postoperative anticoagulation in patients undergoing transcatheter aortic valve implantation (TAVI) with combined high-risk atrial fibrillation (AF). MethodsAll clinical research literature on NOAC and VKA in TAVI patients with high-risk AF was collected using computer searches of PubMed, EMbase, The Cochrane Library, CNKI, VIP, and SinoMed. The retrieval schedule was from inception to January 2023. The Newcastle-Ottawa Scale (NOS) was utilized to provide an assessment of the quality of the included literature. Meta-analysis was performed by applying RevMan 5.4 software to the studies that met the quality criteria. ResultsA total of 24 592 patients were incorporated in 7 eligible papers for meta-analysis. Patients with NOAC had a significantly lower risk of all-cause mortality compared with TAVI patients with combined high-risk AF who had VKA [RR=0.74, 95%CI (0.58, 0.94), P=0.01]. During the first year of follow-up, no apparent difference in all-cause mortality was observed between the two groups [RR=0.57, 95%CI (0.17, 1.88), P=0.35]. After a year of following up on patients treated with VKA, all-cause mortality was higher in the group treated with NOAC, and the difference was statistically meaningful [RR=0.73, 95%CI (0.57, 0.95), P=0.02]. Patients in both groups had early stroke [RR=0.50, 95%CI (0.19, 1.28), P=0.15], follow-up stroke [RR=1.04, 95%CI (0.88, 1.22), P=0.64] and bleeding [RR=0.94, 95%CI (0.73, 1.21), P=0.61], severe or life-threatening hemorrhage [RR= 0.80, 95%CI (0.49, 1.31), P=0.38], and acute kidney injury [RR=0.51, 95%CI (0.16, 1.59), P=0.24] were all non-statistically significant differences. ConclusionCompared with the application of VKA, postoperative anticoagulation with NOAC in TAVI patients with combined high-risk AF may reduces all-cause mortality in patients and may yield additional benefit especially in long-term anticoagulation.
Objective To investigate the risk factors of prolonged postoperative mechanical ventilation for adult patients with atrioventricular septal defect (AVSD). Methods We retrospectively analyzed the clinical data of 76 patients with AVSD aged more than 18 years in our hospital from January 1, 2011 to December 31, 2017. The patients ventilated longer than 24 hours were described as a prolonged ventilation group (n=27) and the others as a normal group (n=49). There were 9 males and 18 females aged 32.22±9.64 years in the prolonged ventilation group, and 16 males and 33 females aged 35.98±11.34 years in the normal group. Perioperative variables between the two groups were compared and selected, and then analyzed by logistic regression analysis. Results The result of univariate analysis showed that there was a statistical difference in weight, preoperative pulmonary artery systolic pressure, duration of cardiopulmonary bypass, the level of postoperative platelet, hemoglobin, blood glucose, lactic acid and serum creatinine, postoperative maximum heart rate and postoperative infection rate between the prolonged ventilated group and the normal group. Multivarable logistic regression showed that preoperative pulmonary artery hypertension (OR=1.056, 95%CI 1.005 to 1.110, P=0.030), prolonged duration of cardiopulmonary bypass (OR=1.036, 95%CI 1.007 to 1.066, P=0.016) and the low postoperative hemoglobin level (OR=0.874, 95%CI 0.786 to 0.973, P=0.014) were the risk factors of prolonged postoperative mechanical ventilation. Conclusion Preoperative pulmonary artery hypertension, long duration of cardiopulmonary bypass and postoperative anaemia are the risk factors associated with prolonged postoperative mechanical ventilation.
ObjectiveTo evaluate the efficacy and safety of modified maze Ⅳ (Cox-maze Ⅳ) in hypertrophic obstructive cardiomyopathy (HOCM) patients.MethodsFrom June 2016 to June 2019, 30 HOCM and persistent atrial fibrillation (pAF) patients received Cox-maze Ⅳ operation with modified extended Morrow operation, including 21 males and 9 females. The average age was 51.36±10.27 years and the average weight was 72.48±11.29 kg. All patients underwent left atrial appendectomy. Recurrence of AF, improvement of symptoms, cardiac function (NYHA) were assessed during follow-up.ResultsThere was no death during the perioperative period. Postoperative left ventricular outflow tract gradient was significantly decreased compared with that before operation (P<0.01), and all systolic anterior motion (SAM) signs disappeared after operation. Thirty patients were all effectively followed up for 3-40 (16.24±8.26) months. During the follow-up period, there was no death, and the cardiac function (NYHA) of all patients recovered to gradeⅠ-Ⅱ. At the end of follow-up, twenty-four patients (80.00%) maintained sinus rhythm, and twenty-seven patients (90.00%) maintained sinus rhythm after amiodarone conversion. Univariate analysis showed that the smoking history (P=0.04), left atrial diameter≥55 mm before operation (P=0.03), left atrial diameter≥50 mm after operation (P=0.02), postoperative tricuspid regurgitation (P=0.02) were closely related to postoperative AF recurrence. The increase of left atrial diameter after operation was an independent risk factor for AF recurrence (P=0.02).ConclusionMorrow/Cox-maze Ⅳ procedure is safe and effective in treatment of patients with HOCM complicated with pAF, which helps to maintain postoperative sinus rhythm, and to improve the cardiac function. The increase of left atrial diameter after operation is an independent risk factor for AF recurrence.
The "2022 AHA/ACC/HFSA guideline for the management of heart failure" replaces the "2013 ACCF/AHA guideline for the management of heart failure" and the "2017 ACC/AHA/HFSA focused update of the 2013 ACCF/AHA guideline for the management of heart failure". The 2022 guideline is intended to provide patient-centric recommendations for clinicians to prevent, diagnose and manage patients with heart failure. Heart failure remains a leading cause of morbidity and mortality globally. The 2022 heart failure guideline provides recommendations based on contemporary evidence for the treatment of these patients. The recommendations present an evidence-based approach to manage patients with heart failure, with the intent to improve quality of care and align with patients’ interests. New recommendations have been created when supported by published data. Value statements are provided for certain treatments with high-quality published economic analyses. This article summarized and interpreted the new concept of heart failure in 2022 guidelines, especially the new evidence and suggestions related to cardiac surgery.
Enhanced recovery after surgery (ERAS) has been proven to reduce surgical injuries, promote recovery, and improve postoperative outcomes in different types of surgeries. A core principle of ERAS is to provide programmatic evidence-based perioperative interventions. An international multidisciplinary expert group provided a statement on clinical practice in each thematic area of ERAS by obtaining a list of potential ERAS elements, and reviewing literature. The version 2024 of "Perioperative care in cardiac surgery: A joint consensus statement by the Enhanced Recovery After Surgery (ERAS) Cardiac Society, ERAS International Society, and the Society of Thoracic Surgeons (STS)" is developed from the version 2019 of "Guidelines for perioperative care in cardiac surgery: Enhanced Recovery after Surgery Society recommendations". The consensus statement group was composed of multidisciplinary experts such as cardiac surgeons, anesthesiologists, intensive care physicians, and nurses, based on personal ERAS knowledge and experience. This article interprets the changes and new statements in the 2024 consensus, which can provide a foundation for the best perioperative practices for adult cardiac surgery patients.
ObjectiveTo evaluate the clinical outcomes of pulmonary valve replacement (PVR) in patients with tetralogy of Fallot (TOF) after re-PVR surgery.MethodsPubMed, EMbase, the Cochrane Controlled Trials Register databases, CNKI, CBM disc and VIP datebases were searched, and study eligibility and data abstraction were determined independently and in duplicate. Literature searches from database establishment to December 2018. The heterogeneity and data were analyzed by the software of Stata 11.0.ResultsOf 4 831 studies identified, 26 studies met eligibility criteria, and invovled with a total of 3 613 patients. The combined 30-day mortality for PVR was 2.2% (95% CI 1.5%-3.1%) and follow-up mortality was 3.4% (95% CI 2.4%-4.9%), re-PVR rate was 6.8% (95% CI 5.1%-9.2%), and the rate of intervention was 11.4% (95% CI 8.0%-16.4%). Subgroup analysis showed that the patient's age range may be a heterogeneous source of mortality during the follow-up period, and there was no statistical heterogeneity for adult patients (P=0.63, I2=0%), with a lower incidence than those including adolescents patients. The type of valve was likely to be a source of retrospective PVR. There was no statistical heterogeneity in bioprosthetic valves and allograft lobes (P=0.24, I2=25%). And the incidence of re-PVR was lower than that of the mechanical valve patients. Heart function classification (NYHA) of patients with TOF after PVR was statistically improved (P<0.05). Electrocardiogram QRS change was not statistically differently (P>0.05). Postoperative MRI findings showed a decrease in RVEDV, an increase in RVEF, a decrease in RV/LV ratio, and a decrease in pulmonary valve (all P<0.05). Funnel map monitoring, Begg test and Egger's test both indicated that there was no publication bias.ConclusionsAccording to the results of the analysis, PVR after TOF surgery is a more mature surgery, the clinical effect was significant, with lower early and long-term mortality. The long-term mortality rate of adolescent patients undergoing PVR is higher than that of adult patients. Long-term outocme of re-PVR or re-intervention is still the main problem affecting the effect of the operation. Indications for surgery and choice of valve need further investigation.
ObjectiveTo explore the association between preoperative, perioperative parameters, especially estimated glomerular filtration rate (eGFR) and postoperative atrial fibrillation (POAF) after modified extended Morrow procedure.MethodsA total of 300 hypertrophic obstructive cardiomyopathy (HOCM) patients who underwent modified extended Morrow procedure in our hospital from January 2012 to March 2018 were collected. There were 197 (65.67%) males and 103 (34.33%) females with an average age of 43.54±13.81 years. Heart rhythm was continuously monitored during hospitalization. The patients were divided into a POAF group (n=68) and a non-POAF group (n=232). The general data, perioperative parameters and echocardiographic results were collected by consulting medical records for statistical analysis. Univariate and multivariate logistic regression models were used to analyze the risk factors for POAF.ResultsOverall incidence of POAF during hospitalization was 22.67% (68/300). Compared with patients without POAF, patients with POAF were older, had higher incidence of chest pain and syncope, lower level of preoperative eGFR, higher body mass index and heart function classification (NYHA), larger preoperative left atrial diameter and left ventricular end diastolic diameter, and longer ventilator-assisted time, ICU stay and postoperative hospital stay. Age, heart function classification (NYHA)≥Ⅲ, hypertension, syncope history and eGFR were independent risk factors for POAF. Receiver operating characteristic curve analysis showed that the area under the curve of eGFR was 0.731 (95%CI 0.677-0.780, P<0.001), and the sensitivity and specificity were 82.4% and 57.8%, respectively.ConclusionIncreased age, high preoperative heart function classification (NYHA), hypertension, preoperative syncope history and decreased eGFR are independent risk factors for POAF in HOCM patients who underwent surgical septal myectomy. Preoperative decreased eGFR can moderately predict the occurrence of POAF after modified extended Morrow procedure.
