The most common cause of mortality after a kidney transplant is a cardiovascular event. This is why most patients with poor cardiovascular status are denied a transplant. A 70-year-old male, ESRD from hypertensive nephropathy, was declined renal transplantation in the United States for advanced age, severe coronary disease and abdominal aortic aneurysm. The patient sought a second chance at a possible transplantation here in the Philippines. After a comprehensive cardiovascular evaluation, he underwent coronary artery bypass graft for a three-vessel disease followed by endovascular aneurysm repair (EVAR) which he tolerated well. After four weeks, he underwent a living-related kidney transplantation with immediate allograft function. On postoperative day 5, after catheter removal, the patient was unable to void spontaneously. He was diagnosed with benign prostatic obstruction and underwent transurethral resection of the prostate. He tolerated this and voided freely since catheter removal. One year later, the patient has a functioning allograft and stable cardiac status. High risk patients with cardiovascular disease may be given a chance at kidney transplantation after a meticulous evaluation and optimization.

OBJECTIVE

This study aims to determine the clinical profile and incidence of in-hospital outcomes of patients who underwent coronary artery bypass graft surgery (CABG) under the Philippine Health Insurance Corporation (Philhealth) Z Benefit Package (PZBP).

METHODS

A retrospective descriptive cohort study. A review of medical records was done from July 2017 to October 2023 to collect data and in-hospital outcomes of patients who underwent CABG surgery under Z benefit package.

RESULTS

One hundred twenty-six patients were included in the study. The mean age of patients was 60 years and majority of them were male and came from NCR. Hypertension was the leading cause of comorbidity. The top two most common in-hospital outcomes were hospital-acquired pneumonia and postoperative atrial fibrillation. Most commonly observed caused of increased length in hospitalization was pneumonia. The mean Society of Thoracic Surgeons (STS) (operative mortality) and Euro scores were 1.04 ± 0.82 and 0.88 ± 0.56, respectively. All patients had successful surgical outcome with no mortality and an average length of stay in the hospital of six days.

CONCLUSIONS

This study will serve as a future reference to enhance screening criteria and improved in-hospital outcomes for those who will undergo CABG under Z benefit package. The study also showed insights on clinical profile and in-hospital outcomes of patients who underwent CABG in our own institution and this may give way to a larger scale of study involving multiple centers who also offer the said program.

OBJECTIVES: To compare perioperative and mid-term results of multiple versus single arterial off-pump coronary artery bypass grafting (OPCABG) in patients with impaired left ventricular function. METHODS: This study was conducted among 86 patients with a left ventricular ejection fraction (LVEF) <50%, who underwent OPCABG at our hospital between January, 2018 and December, 2021. Of these patients, 22 underwent OPCABG with multiple arterial grafts (multiple graft group) and 64 received a single arterial graft in OPCABG (single graft group). The preoperative, intraoperative, and perioperative data were collected, and the patients were followed up for a mean of 29.28±14.84 months. The perioperative outcomes and follow-up results of the patients were compared, and the factors influencing major adverse cardiovascular events (MACE) were identified using logistic regression. Kaplan-Meier analysis was used to compare the postoperative survival rate without MACE. RESULTS: The patients in multiple graft group had a significantly younger age than those in single graft group (P<0.05), but the other baseline data were similar between the two groups (P>0.05). Perioperative mortality, 24-h postoperative drainage volume, length of ICU stay, intubation time, and the incidence of new-onset atrial fibrillation were all similar between the two groups (P>0.05), but the rate of postoperative hypotension was significantly higher in multiple graft group (34.78% vs 11.54%, P=0.009). No significant differences were found in the incidence of MACE or echocardiographic data during the follow-up. Logistic regression identified the female sex (OR: 0.191, 95% CI: 0.049-0.075) and creatinine level (OR: 1.016, 95% CI: 1.000-1.033) as factors affecting postoperative MACE occurrence. Kaplan-Meier analysis showed no significant difference in MACE-free survival rate between the two groups. CONCLUSIONS OPCABG with multiple arterial grafts does not increase severe perioperative complications or the risk of mid-term MACE in patients with impaired left ventricular function.

Objective: To describe the treatment outcomes of patients who underwent coronary artery bypass grafting (CABG) with vein patch angioplasty with internal mammary artery (IMA) grafting of the diffusely diseased left anterior descending (LAD) coronary artery. Methods: This is a retrospective observational study of 26 patients who have undergone vein patch angioplasty of the LAD coronary artery with IMA grafting in three centers by a single surgeon from January 2012 to August 2017. The demographic profile, intraoperative data, and postoperative outcome (including in-hospital mortality and morbidity, perioperative myocardial infarction, and NYHA functional classification) were recorded. Continuous variables were expressed as means with standard deviation and categorical variables summarized as frequencies and percentages. Student’s t-test was used to compare the preoperative versus postoperative mean NYHA functional class. Results: There were 22 (85%) males and 4 (15%) females with a mean age of 62 years (range: 34 to 82). Twentyfive patients (96%) had a three-vessel disease, and one (4%) had a two-vessel disease. Nine patients (35%) had a preoperative myocardial infarction. The mean cardiopulmonary bypass and aortic-cross clamp times were 156 and 118 minutes, respectively. The mean number of vessels grafted was 4.12. Multiple arterial grafting was used in seven patients (27%). There were two in-hospital mortalities (7.7%) and three morbidities (11.5%), including reoperation for bleeding, acute kidney injury, and leg wound infection. Six patients (23%) developed postoperative atrial fibrillation. No patient developed perioperative myocardial infarction. The mean ICU stay was three days, and the mean hospital stay was 10.27 days. The mean NYHA functional class improved from 2.85 preoperatively to 1.5 postoperatively (p<0.00001). Among patients with improvement, postoperative NYHA improved by two functional classes in 38% and by one functional class in 62%. Conclusion Vein patch angioplasty is a valuable technique for diffuse coronary stenosis of the LAD artery with acceptable early results.
Coronary Artery Bypass

BACKGROUND

Implementation of blood conservation protocol may increase the efficiency of blood utilization and optimize the maximum surgical blood ordering schedule (MSBOS) in our institution. The primary objectives of this study are to evaluate the efficient utilization of a fixed blood request of 4 units of packed red blood cells (PRBCs) and to establish an effective MSBOS on primary isolated elective coronary artery bypass graft (CABG).

METHODOLOGY

This was a retrospective, analytical, observational, cohort type of study conducted through chart review of CABG patients from January 2018 to December 2019. Indices used to evaluate blood utilization efficiency were crossmatch to transfusion (C/T) ratio, transfusion probability (T%), and transfusion index (TI). MSBOS was computed based on the data gathered.

RESULTS

A total of 77 patients were included in this study. Blood transfusion based on C/T ratio was associated with body surface area 3 vessels (P = 0.042). Overall, C/T ratio was 2.44, T% was 70.1%, and TI was 1.69. Unutilized blood was measured at 59%. The computed MSBOS for elective CABG was at 2 units (2.53).

CONCLUSION

There is efficient PRBC utilization in primary elective CABG when the blood indices were used. Evidence-based MSBOS is established and the previous 4 units PRBC can be reduced to 2 units to promote C/T ratio

OBJECTIVE: To explore the diagnosis and treatment of acute cerebral infarction following extracorporeal membrane oxygenation (ECMO) therapy in patients with cardiogenic shock to review the literature. METHODS: The clinical data of two patients with cardiogenic shock treated with veno-arterial ECMO (VA-ECMO) complicated with acute cerebral infarction admitted to department of intensive care unit (ICU) of Affiliated Hospital of Guizhou Medical University were retrospectively analyzed and the treatment experience was shared. RESULTS: Case 1 was a 46-year-old male patient who was admitted to the hospital on September 16, 2021, due to "repeated chest tightness, shortness of breath, syncope for 2+ years, and worsened for 15 days. Coronary artery angiography showed 3-vessel coronary artery disease lesions. On October 15, 2021, coronary artery bypass grafting (CABG), pericardial fenestration and drainage, thoracic closed drainage, femoral bypass, thoracotomy exploration, and sternal internal fixation were performed under support of extracorporeal circulation. After surgery, the heart rate was 180-200 bpm, the blood pressure could not be maintained, and the improvement was not obvious after active drug treatment. The right femoral artery and femoral vein were intubated, VA-ECMO support treatment was performed, and the patient was transferred to the ICU. Intra-aortic balloon pump (IABP) was treated on the day of transfer because the circulation could not be maintained. Due to acute cerebral infarction in the left hemisphere and right parieto-occipital lobe, subfalcine herniation, tentorial herniation, the patient ultimately died after withdrawing from ECMO. Case 2 was a 43-year-old male patient who was admitted to the hospital on June 29, 2021, with "fever for 8 days and vomiting for 4 days". Bedside ultrasound showed cardiac enlargement and diffuse wall motion reduction in the left and right ventricles. On June 30, 2021, the patient underwent catheterization through the right femoral artery and femoral vein, VA-ECMO support, and was transferred to ICU for treatment. Acute cerebral infarction on both sides of the cerebellum occurred, and after treatment, the patient was discharged with mild impairment of daily living ability. CONCLUSIONS Strengthen monitoring of anticoagulation; regular neurological examination of patients undergoing ECMO therapy; ECMO under light sedation or awake can be performed if the condition permitsif the condition permits, perform light sedation or awake ECMO, which helpful for the early detection of nervous system injury.

Objective: To evaluate the predictive value of the proportion of hibernating myocardium (HM) in total perfusion defect (TPD) on reverse left ventricle remodeling (RR) after coronary artery bypass graft (CABG) in patients with heart failure with reduced ejection fraction (HFrEF) by ^99mTc-methoxyisobutylisonitrile (MIBI) single photon emission computed tomography (SPECT) myocardial perfusion imaging (MPI) combined with ¹⁸F-flurodeoxyglucose (FDG) gated myocardial imaging positron emission computed tomography (PET). Methods: Inpatients diagnosed with HFrEF at the Cardiac Surgery Center, Anzhen Hospital of Capital Medical University from January 2016 to January 2022 were prospectively recruited. MPI combined with ¹⁸F-FDG gated PET was performed before surgery for viability assessment and the patients received follow-up MPI and ¹⁸F-FDG gated PET at different stages (3-12 months) after surgery. Δ indicated changes (post-pre). Left ventricular end-systolic volume (ESV) reduced at least 10% was defined as RR, patients were divided into reverse remodeling (RR+) group and the non-reverse group (RR-). Binary logistic regression analysis was used to identify predictors of RR. Receiver operating characteristic (ROC) curve analysis was performed and the area under the curve (AUC) was calculated to assess the cut-off value for predicting RR. Additionally, we retrospectively enrolled inpatients with HFrEF at the Cardiac Surgery Center, Anzhen Hospital of Capital Medical University from January 2021 to January 2022 as the validation group, who underwent MPI and ¹⁸F-FDG gated PET before surgery. Echocardiography was performed before CABG and after CABG (3-12 months). In the validation group, the reliability of obtaining the cut-off value for the ROC curve was verified. Results: A total of 28 patients with HFrEF (26 males; age (56.9±8.7) years) were included in the prospective cohort. HM/TPD was significantly higher in the RR+ group than in the RR- group ((51.8%±17.9%) vs. (35.7%±13.9%), P=0.016). Binary logistic regression analysis revealed that HM/TPD was an independent predictor of RR (Odds ratio=1.073, 95% Confidence interval: 1.005-1.145, P=0.035). ROC curve analysis revealed that HM/TPD=38.3% yielded the highest sensitivity, specificity, and accuracy (all 75%) for predicting RR and the AUC was 0.786 (P=0.011). Meanwhile, a total of 100 patients with HFrEF (90 males; age (59.7±9.6) years) were included in the validation group. In the validation group, HM/TPD=38.3% predicted RR in HFrEF patients after CABG with the highest sensitivity, specificity and accuracy (82%, 60% and 73% respectively). Compared with the HFrEF patients in the HM/TPD<38.3% group (n=36), RR and cardiac function improved more significantly in the HM/TPD≥38.3% group (n=64) (all P<0.05). Conclusions: Preoperative HM/TPD ratio is an independent factor for predicting RR in patients with HFrEF after CABG, and HM/TPD≥38.3% can accurately predict RR and the improvement of cardiac function after CABG.
