Mechanical Circulatory Support in Delayed Surgery of Post-Infarction Ventricular Septal Rupture in Patients in Cardiogenic Shock—A Review

Post-infarction ventricular septal rupture (VSR) is a serious complication of myocardial infarction, which, in its natural course or treated medically, is related to high mortality rate. Surgical intervention remains the treatment of choice. Recent studies have shown that delayed surgery is related to better outcomes in comparison with urgent surgery; however, in many studies the impact of the patients’ initial hemodynamic status on the treatment outcomes often remains unclear. In this review, we analyze the outcomes of delayed surgical treatment of patients in cardiogenic shock in the course of post-infarction ventricular septal defect stabilized with preoperative use of mechanical circulatory support. We evaluate the importance of various types of mechanical circulatory devices (MCD), such as extracorporeal membrane oxygenation, Tandem Heart, Impella, and intra-aortic baloon pump (IABP) in preoperative stabilization of patients, and the most suitable time for surgery, and we also present the features of ideal MCD for patients with VSR. A search of Pubmed to identify studies concerning the use of MCD in patients in cardiogenic shock in the course of VSR qualified for delayed surgery was conducted in January 2022. A total of 16 articles with three or more patients described were analyzed in this study. The preoperative use of MCD in patients in cardiogenic shock and delayed surgery as a main part of treatment seems to be a promising direction, however, it requires further research.

Survival and risk factors associated with surgical repair of ventricular septal rupture after acute myocardial infarction: A single-center experience.

ObjectiveTo analyze the survival and risk factors associated with the surgical treatment of ventricular septal rupture (VSR) after acute myocardial infarction (AMI).MethodsWe retrospectively analyzed 45 consecutive patients with VSR after AMI whose procedures were performed in the Department of Cardiovascular Surgery at the General Hospital of Northern Theater Command between January 2012 and December 2021. Relevant clinical data, surgery-related conditions, and follow-up data of all patients were summarized. Patients were divided into the survival group and the death group. The Kaplan–Meier method and log-rank test were used to determine the cumulative incidence of all-cause mortality. Multivariate logistic regression was used to evaluate the independent risk factors for all-cause mortality.ResultsThe average postoperative follow-up time was 42.1 ± 34.1 months. The overall mortality rate was 20% (9/45 patients) and the operative mortality rate was 8.9% (4/45 patients). Logistic analysis showed that the death group had higher serum creatinine (127.32 ± 47.82 vs. 82.61 ± 27.80 μmol/L, respectively; P = 0.0238) and N-terminal pro-B-type natriuretic peptide (NT-proBNP) [8,654.00 pg/mL (6,197.00–11,949.00 pg/mL) vs. 4,268.96 pg/mL (1,800.00–7,894.00 pg/mL), respectively; P = 0.0134] levels than the survival group. The cardiopulmonary bypass time (CPB) was longer in the death group than in the survival group [131.00 min (121.00–184.00 min) vs. 119.00 min (103.00–151.50 min), respectively; P = 0.0454]. Significantly more red blood cells were transfused in the death group than in the survival group [11.60 units (6.10–16.50) vs. 3.75 units (0.00–7.00 units), respectively; P = 0.0025]. Intra-aortic balloon pump (IABP) implantation (P = 0.016) and ventilation time (P = 0.0022) were risk factors for mortality. A 1-month landmark analysis showed that compared with patients with VSR to surgical time >14 days, patients who underwent surgery within 14 days had a higher rate of all-cause mortality (25.00 vs. 3.33%; log-rank P = 0.023). Patients with VSR within 14 days also had a higher rate of residual shunts that were higher than moderate. Multivariate analysis showed that transfusion of red blood cells and NT-proBNP level were risk factors for all-cause mortality, as well as major adverse cardiovascular and cerebrovascular events.ConclusionsSurgical repair resulted in good outcomes for patients with VSR after AMI. Patients with VSR to surgical time >14 days had a lower rate of all-cause mortality. Treatment strategies for VSR should be based on the patient's condition and comprehensively determined through real-time evaluation and monitoring.

Inferior ST-Segment Elevation Can Predict In-Hospital Mortality in Patients with Anterior Myocardial Infarction Complicated by Ventricular Septal Rupture.

Background Electrocardiogram (ECG) findings in patients with anterior wall myocardial infarction (MI) complicated by ventricular septal rupture (VSR) have rarely been studied. Methods We conducted a single-center retrospective study among patients with anterior MI complicated by VSR over the past ten years. The presence of ST-segment elevation (STE) in inferior leads and new onset of complete right bundle branch block (RBBB) on ECG were studied for the prediction of in-hospital mortality. Results Among the 85 patients enrolled, 45 (52.9%) were male, with a median age of 70 years. Sixty-five patients (76.5%) died in the hospital, and the remaining 20 patients (23.5%) had improved conditions and were discharged. Inferior STE was present in 35 patients (41.2%), including 32 patients in the death group and 3 patients in the survival group (P = 0.005). New-onset RBBB was present in 25 patients (29.4%), with 22 patients in the death group and 3 patients in the survival group (P = 0.103). Multivariate logistic regression showed that inferior STE was an independent predictor of in-hospital death in patients with anterior MI and VSR (OR: 14.488; 95% CI: 1.708-122.887; P = 0.014). Conclusions In patients with anterior MI complicated by VSR, inferior STE was associated with a higher risk of in-hospital mortality.

SUCCESSFUL PERCUTANEOUS CLOSURE OF POST-MYOCARDIAL INFARCTION, VENTRICULAR SEPTAL RUPTURE IN A PATIENT WITH COVID-19: A CASE REPORT

Ventricular septal rupture (VSR) is a rare life-threatening complication of myocardial infarction. Transcatheter or surgical closure could be both used for VSR management but using the transcatheter method is associated with less mortality rate. Regardless of the controversial issues, the best timing for the procedure in post-myocardial infarction, the patient’s clinical condition and underlying diseases might complicate the management. We present a patient with positive COVID -19 test who developed VSR, following myocardial infarction. Successful transcatheter closure was carried out and the health condition improved, as well.

Transesophageal Echocardiographic Illustration of Postinfarction Ventricular Septal Rupture

AbstractPostinfarction ventricular septal rupture (VSR) is a rare but dreaded mechanical complication of myocardial infarction. Moreover, patient develops cardiogenic shock or congestive heart failure requiring early surgical intervention. To optimize surgical repair, perioperative confirmation, determining location of VSR and adequacy of repair, is mandatory. Assessment can be obtained by the transesophageal echocardiography (TEE). Use of two- and three-dimensional TEE techniques clearly delineate size and shape of septal rupture and involvement of other cardiac structures. We report a patient presenting with postinfarction VSR for elective VSR repair and surgical revascularization and implication of TEE in perioperative management.

Death-related risk factors analysis of surgical treatment of myocardial infarction combined with ventricular septal rupture

Objective: To in vestigate the death-related risk factors of surgical treatment of myocardial infarction (MI) combined with ventricular septal rupture (VSR). Methods: The clinical data of patients (68 cases) with ventricular septal rupture after myocardial infarction (PI-VSR) from January 2008 to December 2020 in Beijing Anzhen Hospital were retrospectively selected and analyzed. We followed up the surviving patients and divided them into the survival group and the death group according to the perioperative and follow-up results. The univariate analysis was performed on various indicators, and the Cox regression analysis was used to analyze the risk factors related to postoperative death. Results: A total of 68 patients (42 were male and 26 were female, with age 44-82 (64.3±8.2) years after surgical treatment of myocardial infarction combined with ventricular septal rupture were enrolled, 9 patients died during the perioperative period, 59 surviving patients were followed up for 0.1-10.5 years(mean, 4 years), and 7 deaths during follow-up. Based on this, 52 patients were selected as the survival group while 16 patients as the death group. The results of univariate analysis showed that age, VSR to operation time less than 7 days, killip grade ≥ grade 3, cardiogenic shock, preoperative use of IABP, emergent surgery were related to postoperative death. The factors with P<0.2 factors in univariate analysis were selected into the multivariate Cox regression analysis. Age ([OR=1.110(1.012-1.217), P=0.026], platelet count [OR=0.990(0.981-0.999), P=0.031], D dimer (OR=1.002[1.001-1.003], P=0.003), cardiogenic shock (OR=6.084[1.729-21.405], P=0.005) were independent risk factors for postoperative death. All patients were followed up, the survival rate of 2-year, 4-year, 6-year, 8-year, and 10-year was 77.5%, 77.5%, 71.0%, 71.0%, and 71.0%, respectively. Conclusions: Age, platelet count, D-dimer, and cardiogenic shock are risk factors for death after surgical treatment of myocardial infarction combined with ventricular septal rupture. Surgery is an effective method for the treatment of myocardial infarction combined with ventricular septal rupture. Long-term prognosis of the surviving patients during perioperative are relatively better.

Benefits and Risks of Delayed Surgery for Ventricular Septal Rupture after Acute Myocardial Infarction.

The timing of surgery for ventricular septal rupture (VSR) after acute myocardial infarction (AMI) remains controversial. This study investigated the benefits and risks of delayed surgery for post-AMI VSR and examined differences in echocardiographic findings between early and delay groups.A total of 38 consecutive patients with post-AMI VSR who underwent surgery at our hospital between May 2003 and November 2020 were retrospectively analyzed. Our strategy was to delay surgery until 2 weeks after AMI. If patients demonstrated organ dysfunction, we considered early surgery. Patients were divided into early (n = 20; 53%) and delay (n = 18; 47%) groups. Risks and benefits were investigated based on echocardiographic findings during the waiting period. The delay group had more preoperative intravenous catheter infections (P = 0.008) but fewer reoperations (P = 0.02) and lower operative mortality (P = 0.04) than the early group. The VSR defect diameter and total pulmonary blood flow to total systemic blood flow (Qp/Qs) increased in both groups while waiting. Nevertheless, the early group had a significantly higher Qp/Qs change rate than the delay group (P = 0.05). The 30 day and hospital mortality rates were 5.3% and 13.2%, respectively.The VSR defect diameter and Qp/Qs in both groups increased with time and can therefore become risk factors. Nonetheless, the benefit of waiting exceeded the risk because our outcomes were better than those previously reported.

Hyperlactatemia as a Risk Stratification for Postinfarction Ventricular Septal Rupture.

Surgical repair for postinfarction ventricular septal rupture (VSR) is a challenging operation, especially in the acute phase with unstable hemodynamics. We retrospectively examined the value of measuring lactate, which can be a quantitative indicator of end-organ ischemia caused by multiple factors including ineffective cardiac output, for risk stratification in patients undergoing surgical repair. From April 2008 to December 2018, 33 consecutive patients were admitted to our hospital with a diagnosis of VSR and underwent VSR repair surgery within 24 hours of admission. We categorized patients into 3 groups based on the distribution of preoperative blood lactate level: <5 mmol/L (n = 16), 5 to 10 mmol/L (n = 11), and >10 mmol/L (n = 6). There was no intraoperative death, but the prognosis for patients with lactate >10 mmol/L was extremely poor, with a median postoperative survival time of only 23 days [25th percentile 6, 75th percentile 30]. Five of 6 patients (83%) died within 30 days after surgery. The risk-adjusted hazard ratio (95% confidence interval) for mortality per 1 SD (0.41-unit) increase in log-transformed preoperative lactate level (equivalent to a 4.10-fold increase) was 2.85 (1.57 to 5.19). Patients with lactate 5 to 10 mmol/L had 3.95-fold and those with lactate >10 mmol/L had 6.03-fold higher risk of mortality than those with lactate <5 mmol/L. Elevation of preoperative serum lactate is significantly associated with mortality in patients who underwent VSR repair. The findings of this study highlight the value of measuring lactate level for risk stratification.

Ventricular septal rupture after blunt chest trauma: a case report

Cardiac injury, including myocardial contusion and valvular damage, is a common complication of blunt chest trauma; however, traumatic ventricular septal rupture is a rare complication. We encountered a rare case of ventricular septal rupture following blunt chest trauma that was successfully repaired by emergency surgery. The mechanism underlying rupture may involve acute compression of the heart between the sternum and the vertebral column when the ventricle is filled, thereby causing a sudden increase in intraventricular pressure and leading to septal rupture. Emergency operation should be considered in cases of large defects and hemodynamic instability.

Ventricular Septal Rupture Complicating Acute Myocardial Infarction: A Preventable Complication? Case Report and Review of the Literature

Despite the significant reduction in mortality from acute myocardial infarction in recent decades due to adequate medical management, cardiac monitoring, and early reperfusion, the mortality rate from ventricular septal rupture remains considerable. The risk factors for this complication have been the subject of several studies such as hypertension, advanced age, female gender, absence of angina pectoris, and anterior location of the ischemia. Surgical repair techniques have evolved over time, but the prognosis remains very poor with a mortality rate unchanged since 1990. This is why it is very important to know the clinical manifestations to specify the diagnosis by echocardiography and to allow urgent medical and surgical management. We will illustrate this fatal complication of myocardial infarction and review the different factors that predict its development through a clinical case and a review of the literature.

The evaluation of levosimendan in patients with acute myocardial infarction related ventricular septal rupture undergoing cardiac surgery: a prospective observational cohort study with propensity score analysis

Study objectiveThe purpose of the present study was to evaluate the efficacy of levosimendan in patients with acute myocardial infarction related ventricular septal rupture (AMI-VSR) underwent cardiac surgery.DesignProspective observational cohort study with propensity score analysis.PatientsThere were 261 patients with AMI-VSR in our study. After 1:1 propensity matching, 106 patients (53 levosimendan and 53 control) were selected in the matched cohort.InterventionsNone.MeasurementsPatients who received levosimendan were assigned to the levosimendan group (n = 164). The patients who were not received were levosimendan assigned to the control group (n = 97). The levosimendan was initiated immediately after cardiopulmonary bypass. Then, it has been maintained during the postoperative 3 days. The poor outcomes were identified as follows: death and postoperative complications (postoperative stroke, low cardiac output syndromeneeded mechanical circulatory support after surgery, acute kidney injury (≥ stage III), postoperative infection or septic shock, new developed atrial fibrillation or ventricular arrhythmias).Main resultsBefore matching, the control group had more length of ICU stay (6.69 ± 3.90 d vs. 5.20 ± 2.24 d, p < 0.001) and longer mechanical ventilation time (23 h, IQR: 16–53 h vs. 16 h, IQR: 11–23 h, p < 0.001). Other postoperative outcomes have not shown significant differences between two groups. After matching, no significant difference was found between both groups for all postoperative outcomes. The Kaplan–Meier survivul estimate and log-rank test showed that the 90-day survival had no significant differences between two groups before and after matching.ConclusionOur study found that a low-dose infusion of levosimendan in AMI-VSR patients underwent surgical repair did not associated with positively affect to postoperative outcomes.

Abnormal Electrocardiogram in a Man Presenting With Dyspnea and Chest Pain.

A 70-year-old man with a history of smoking presented at the emergency department with dyspnea and a 24-hour history of intermittent chest pain that had acutely worsened. His heart rate was 128 beats/min; blood pressure, 114/81 mmHg; respiratory rate, 24 breaths/min; and oxygen saturation, 85% on 4 L of oxygen. He had bibasilar crackles and a grade 3/6 holosystolic murmur over the left sternal border. A basic metabolic panel showed nothing unusual. A coronavirus nasopharyngeal swab test was negative. The patient's N-terminal pro-brain-type natriuretic peptide level was 1,583 pg/mL (normal, &lt;100 pg/mL), and his cardiac troponin I level was 39 ng/mL (normal, ≤0.04 ng/mL). He became hypoxic and needed intubation. He was started on intravenous vasopressors and was taken to the cardiac catheterization laboratory, where an intra-aortic balloon pump was placed. His presenting electrocardiogram (ECG) is shown below (Fig. 1).In addition to ST-segment-elevation myocardial infarction (STEMI), what diagnosis should be suspected from this ECG?B) Ventricular septal ruptureIn cases of delayed STEMI, mechanical complications can occur. The differential diagnosis in acute myocardial infarction (AMI) complicated by a holosystolic murmur includes papillary muscle rupture (PMR) and ventricular septal rupture (VSR). Free wall rupture would not present with a holosystolic murmur, and aortic dissection resulting in aortic regurgitation would cause a diastolic murmur. Patients with acute PMR typically present with shock and acute pulmonary edema. In acute PMR, the systolic murmur may be soft or absent, given pressure equalization between the left ventricle and left atrium; conversely, in VSR, there is hemodynamic compromise and a harsh systolic precordial murmur.Inferior and anterior STE with inferior Q waves, such as in our patient's ECG, should raise suspicion for VSR.1 Hayashi and colleagues2 observed STE in the inferior and anterior leads in 42.9% of patients who had VSR, but in only 3.6% of patients without VSR. Moreover, abnormal Q waves appeared in all inferior leads (II, III, and aVF) in 44.4% of patients with VSR but in only 4% of those without.2 Whereas the ventricular septum receives a dual blood supply from the left anterior descending coronary artery (LAD) and right coronary artery, in a dominant “wrap-around” LAD, the ventricular apex is supplied only by the LAD. Occlusion of the LAD (Fig. 2, arrow) results in necrosis of the anterior and inferior walls, leading to STE in the anterior and inferior leads, and a risk of VSR (Fig. 3, arrow) if reperfusion is delayed.3 This case highlights that, in AMI, an ECG showing STE in the anterior and inferior leads with inferior Q waves should raise suspicion for VSR.Conflicts of interest: NoneFunding: None

Triple patch technique to repair ventricular septal rupture.

Postinfarction ventricular septal rupture (VSR) remains an important and life-threatening complication of myocardial infarction (MI). Although several techniques have improved surgical outcomes of postinfarction VSR, the treatment is still challenging with a high mortality rate. In addition, it is well known that a postoperative residual shunt after VSR repair is associated with poor outcomes; however, late outcomes involving patients with a residual shunt after VSR repair are lacking. This paper presents the early and late outcomes of patients who underwent the triple patch technique to repair a VSR and the usefulness in reducing a postoperative residual shunt. The main process of this technique is that the patch is gently placed on the myocardium with over and over suture and is firmly attached using glue. Therefore, the triple patch technique is simple and easy to perform, and is designed to minimize residual shunt and exclude infarcted myocardium. In the present keynote lecture, we describe our surgical technique and the results of VSR repair.

Effects of concomitant coronary artery bypass grafting on early and late mortality in the treatment of post-infarction mechanical complications: a systematic review and meta-analysis.

Mechanical complications of acute myocardial infarction represent life-threatening events, including ventricular septal rupture (VSR), left ventricular free-wall rupture (LVFWR) and papillary muscle rupture (PMR). In-hospital mortality is high, even when prompt surgery can be offered. The role of concomitant coronary artery bypass grafting (CABG) in the surgical treatment of these conditions is still debated. A systematic review of the literature, from 2000 onwards, about these complications was performed, analyzing data of subjects receiving versus not-receiving concomitant CABG. Primary outcome was early mortality. Secondary outcome was late mortality for hospital survivors. Subgroup analysis for VSR, LVFWR and PMR was also performed. Thirty-six studies were identified, including 4,321 patients (mostly VSR-related). Preoperative coronarography was performed in 92.2% of the cases, showing single-vessel disease in 54.3% of patients. Concomitant CABG rate was 49.0%. Early mortality was 32.6% and late mortality was 40.0% with 5.2 years of mean follow-up. The analysis showed no difference in early (OR 0.96; P=0.60) or late mortality (RR 0.91; P=0.49) between CABG and non-CABG group. In subgroup analysis, concomitant CABG was associated with significantly lower mortality at long term for PMR (RR 0.42; P=0.001), although it showed a higher, but not significant, mortality in VSR (RR 1.24; P=0.20). Concomitant CABG in the treatment for post-infarction mechanical complications showed no significant impact on both early and late mortality, although deserving some distinctions among different types of complication and single versus multiple vessel disease. However, larger, dedicated studies are required to provide more consistent data and evidence.

Post-infarction ventricular septal rupture.

Coronary reperfusion therapies have led to a reduction in the incidence of mechanical complications of acute myocardial infarction (AMI), but the associated mortality of these complications has remained high. Ventricular septal rupture is the most common mechanical complication after myocardial infarction and occurs in approximately 0.21% with ST-segment elevation myocardial infarction and in 0.04% with non-ST-segment elevation myocardial infarction. Surgery is the only definitive treatment but it is associated with high operative mortality and morbidity and, in some centers, alternative treatment with mechanical support of circulation and trans-catheter closure of the defect is being used. We continue to believe that immediate surgery offers the best opportunity for long-term survival. Patients should be taken directly to the operating room or via the heart catheterization laboratory if the coronary artery anatomy is unknown. This should be done as soon as the diagnosis is made, as acute rupture of the interventricular septum is a surgical emergency. The operative technique of infarct exclusion has been our preferred method and when performed in hemodynamically stable patients, the operative mortality is around 10%, although much higher in patients in cardiogenic shock. Patch dehiscence and persistent shunts are uncommon after closure of the defect using this technique. Delaying operative intervention in hemodynamically stable patients frequently leads to cardiogenic shock and multi-organ failure. Transcatheter closure of these acute septal lesions is complex, not necessarily feasible in all patients, and there is no evidence that the results are superior to surgery.

Pre- and post-operative mechanical circulatory support in surgical repair of post-acute myocardial infarction mechanical complications.

The outcomes of patients with acute myocardial infarctions (AMI) have significantly improved with advances in early reperfusion strategies; however, patients with massive infarcts or those who do not receive timely revascularization may develop mechanical complications of AMI. The most common mechanical complications are ventricular septal rupture (VSR), acute mitral regurgitation (MR) due to papillary muscle rupture, and free-wall rupture. Each complication is associated with a high risk of morbidity and mortality, and requires a multidisciplinary approach for prompt diagnosis and hemodynamic stabilization. Surgery is the mainstay of therapy but is associated with poor outcomes if performed too early during the treatment course for VSR or if performed too late with MR and free wall rupture. Optimal timing for surgery in combination with temporary circulatory support may be a feasible strategy for better results.

Postoperative outcomes in patients with post infarction ventricular septal defect – Institutional experience

Context: Postinfarction ventricular septal defect (VSD) is a rare but serious complication of myocardial infarction with a reported incidence of 1% to 3% in the pre thrombolytic era and &lt;0.5% post thrombolytic therapy. Risk of death is greatest immediately after myocardial defect and then gradually declines. Early surgical treatment is recommended; however, surgical repair is associated with a high rate of mortality. Aim: To investigate the immediate survival outcome and prognostic factors associated with surgical repair of postinfarction ventricular septal rupture at our institute over a 3-year period. Materials and Methods: From April 2012 to April 2015, 32 patients underwent surgical repair of post-infarction ventricular septal rupture at our institute. Patients were identified from the electronic medical records database and preoperative, intraoperative, and postoperative variables were retrieved. Multiple perioperative variables such as anthropometric data, demography, and clinical history and preoperative details such as echocardiographic indices, coronary angiography, and intraoperative variables were analyzed. The outcomes were compared between the survivors and nonsurvivors. Results: Overall, younger patients tolerated the disease and the surgery better than the older population (59.96 ± 10.67 vs. 69.11 ± 8.11; P = 0.02). Female sex, cardiogenic shock (n = 20, 86.95% vs. n = 2, 22.22%; P = 0.001), and emergency surgery were independently associated with higher risk of postoperative mortality. History of systemic hypertension was found to be significantly associated with poor postoperative outcomes (survivors n = 9, 39.1% vs. nonsurvivors n = 8, 88.9%; P = 0.017). In our series, the overall mortality was 28.1% (n = 9). Higher NYHA class at presentation, intra-aortic balloon pump requirement and low ejection fraction are all independently associated with poor outcomes. Longer interval between the myocardial infarct and surgical repair is associated with a lower risk of operative mortality. Preoperative renal dysfunction (61.77 ± 19.04 vs. 41.36 ± 21.15; P = 0.025) and postoperative renal dysfunction (65.26 ± 28.81 vs. 27.27 ± 9.04; P = 0.001) is one of the most important predictors of postoperative outcome. The duration of aortic cross-clamp and cardiopulmonary bypass was not associated with early mortality in this study (89.17 ± 42.70 vs. 97.11 ± 76.38; P = 0.775). Conclusion: Postinfarction VSD still remains one of the most challenging conditions to treat surgically with considerable early mortality. Although percutaneous device closure and left ventricular assist devices may be used as a method to stabilize the patient preoperatively and improve the chances of survival after surgery, it is currently not advocated as a definitive treatment option. All efforts should be made to predict and prevent postoperative renal dysfunction as it is the single-most important factor affecting both short- and long-term survival outcomes.
