Post infarction ventricular septal defect-can we do better?

Journal of Pharmaceutical Research International

Aims: Despite the existence of numerous studies devoted to predictors of 30-day mortality in patients with post-myocardial infarction (MI) ventricular septum defect (VSD), the choice of surgical treatment tactics for post-MI VSD remains an item of discussion. The purpose of the research was to determine the most significant risk factors of 30-day mortality in patients with post-MI VSD in order to optimize the tactics of such patients’ surgical repair. Study design: The retrospective analysis of the results of a comprehensive examination and surgical treatment of 88 in-patients with post-MI VSD for the period of 2002-2019 was carried out. Results: As follows of the research findings, independent predictors of 30-day mortality in patients with post-MI VSD were determined. The predictors identified were combined into a Scoring system to stratify the risk of surgical failure in patients with post-MI VSD. Modelling the surgery outcomes makes it possible to optimize the tactics of surgica...

The study aimed to identify the factors affecting the prognosis of post myocardial infarction (MI) ventricular septal rupture (VSR) and to develop a protocol for its management. This was a single center, retrospective-prospective study (2009-2014), involving 55 patients with post MI VSR. The strengths of association between risk factors and prognosis were assessed using multivariate logistic regression analysis. The UNM Post MI VSR management and prognosis scoring systems (UPMS & UPPS) were developed. Thirty-day mortality was 52.5% (35% in the last 3 years). Twenty-eight (70%) patients underwent concomitant coronary artery bypass grafting. Residual ventricular septal defect was found in 3 (7.5%) patients. The multivariate analysis showed low mean blood pressure with intra-aortic balloon pump (OR 11.43, P=0.001), higher EuroSCORE II (OR 7.47, P=0.006), higher Killip class (OR 27.95, P=0.00), and shorter intervals between MI and VSR (OR 7.90, P=0.005) as well as VSR and Surgery (OR 5....

Objectives: Ventricular septal rupture is a rare but feared complication after acute myocardial infarction. Most reports about outcome after surgical treatment are single center experiences. We investigated the results after surgical repair in all patients in Sweden during a 7-year period. Methods: All patients undergoing surgical repair 1992-1998 were identified with the aid of the Swedish Heart Surgery Registry. The patients (nZ189, 63% men, mean age 69G8 years) were operated at 10 different centers. Pre-and peri-operative variables were collected from the Registry and individual patient charts. Mortality was calculated and a Cox proportional hazards regression model was used to identify independent predictors for early and late mortality. Mean follow-up was 2.4 years. Results: Seventy-seven of the 189 patients died within 30 days (41%). Urgent repair (Risk Ratio 4.2 (2.0-8.9), P!0.001) and posterior rupture (RR 2.1 (1.3-3.4), PZ0.002) were independent predictors of 30-day mortality. Total cumulative survival (Kaplan-Meyer) was 38% at 5 years. For patients that survived the first 30 days (nZ112), 5 year cumulative survival was 67%. Independent predictors for mortality after 30 days were number of concomitant coronary anastomoses (RR 1.5 (1.2-2.0), PZ0.001), residual postoperative shunt (RR 2.7 (1.4-5.4), PZ0.004) and postoperative dialysis (RR 3.4 (1.5-7.5), PZ0.003). Conclusions: Early mortality after surgical repair of post infarction septal rupture is still considerable. Early repair and posterior rupture are predictors of early mortality. Long-term survival in patients surviving the immediate postoperative period is limited by pre-existing coronary artery disease, postoperative renal failure and the presence of a residual postoperative shunt.

Rupture of the ventricular septum complicates acute myocardial infarction in 0.2% of cases in the thrombolytic era. Ventricular septal defect (VSD) has a mortality of 90-95% in medically managed and 19-60% in surgically treated patients. A retrospective analysis was performed of 41 patients, 26 females (63.4%) and 15 males (36.6%), average age 67.5 ± 15 years, with post-infarction VSD who were treated in the VUL SK intensive cardiology unit between 1991 and 2007. Thirty-seven patients had hypertension (90.2%); anterior wall acute myocardial infarction (AMI) was found in 27 patients (68%). VSD was more frequent in women than in men (p=0.043). In 36 patients (87%) treatment was started 24 hours or later after the development of AMI symptoms. In 34 patients (83%) the rupture occurred during the first episode of AMI and in the majority of these (19 patients, 46.3%), preoperative coronary angiography demonstrated disease of only one coronary artery. During the first 10 days after the ons...

Post-myocardial infarction (MI) ventricular septal defects (PIVSD) are an uncommon but life-threatening complication of acute MI. Although surgical closure has been the standard of care, mortality, and recurrence of VSD remain high even after emergent surgery. Transcatheter VSD closure (TCC) devices have become an alternative or adjunct to surgical closure. Online database search was performed for studies that included adults with PIVSD who underwent medical treatment (MT) alone, surgical closure (SC) (early or late), and TCC (early, late, or for post-surgical residual VSD). Twenty-six studies were included with a total of 737 patients who underwent either MT (N = 100), SC (early (n = 167), late (n = 100)), and TCC (early (n = 176), late (n = 115), or post-surgical residual VSD (n = 79)). The 30-day mortality among MT group was 92 ± 6.3%, among SC was 61 ± 22.5% (early 56 ± 23%, late 41 ± 30%), and for all TCC patients was 33 ± 24% (early 54 ± 32.7%, late 16 ± 26%), and TCC for post...

Acute myocardial infarction (AMI), despite advances in health care delivery systems, educa‐ tion, and primary prevention still remains a significant problem. Fortunately, with these ad‐ vances and early interventions, there has been a decline in the incidence of mechanical complications. Unfortunately, while becoming less common, when mechanical complica‐ tions occur and despite advances and evolving techniques in the surgical management of these problems, morbidity and mortality remain high. Post-myocardial infarction ventricu‐ lar septal rupture (PI-VSD) has challenged and intrigued clinicians for years. The timing of presentation can be quite variable, as they tend to occur in patients several days after their initial cardiovascular insult (acute PI-VSD) – and unfortunately, they can occur in patients who appear to otherwise be doing well. In addition, while less common, some patients might not present until weeks, if not longer, after their AMI with symptoms prompting a work-up ...

Background: To review the experience of surgical repair of post-infarction ventricular septal rupture (VSR) and analyze the associated outcomes and prognostic factors. Methods: Following approval from the Singhealth Centralised Institutional Review Board (reference: 2011/881/C), a retrospective review was performed on 38 consecutive patients who had undergone surgical repair of postinfarction VSR between 1999 and 2011. Continuous variables were expressed as either mean ± standard deviation or median with 25 th and 75 th percentiles. These were compared using two-tailed t-test or Mann-Whitney U test respectively. Categorical variables were compared using chi-square or Fisher's exact test. To identify predictors of operative mortality, univariate analysis of perioperative variables followed by multivariate analysis of significant univariate risk factors was performed. A two-tailed p-value < 0.05 was used to indicate statistical significance. Results: Mean age was 65.7 ± 9.4 years with 52.6% males. The VSR was anterior in 28 (73.7%) and posterior in 10 patients. Median interval from myocardial infarction to VSR was 1 day (1, 4). Pre-operative intra-aortic balloon pump was inserted in 37 patients (97.8%). Thirty-six patients (94.7%) underwent coronary angiography. Thirty-five patients (92.1%) underwent patch repair. Mean aortic cross clamp time was 82 ± 40 minutes and mean cardiopulmonary bypass time was 152 ± 52 minutes. Coronary artery bypass grafting (CABG) was performed in 19 patients (50%), with a mean of 1.5 ± 0.7 distal anastomoses. Operative mortality within 30 days was 39.5%. Univariate analysis identified emergency surgery, New York Heart Association (NYHA) class, inotropic support, right ventricular dysfunction, EuroSCORE II, intra-operative red cell transfusion, post-operative renal failure and renal replacement therapy (RRT) as predictors of operative mortality. Multivariate analysis identified NYHA class and postoperative RRT as predictors of operative mortality. Ten year overall survival was 44.4 ± 8.4%. Right ventricular dysfunction, LVEF and NYHA class at presentation were independent factors affecting long-term survival. Concomitant CABG did not influence early or late survival. Conclusions: Surgical repair of post-infarction VSR carries a high operative mortality. NYHA class at presentation and post-operative RRT are predictors of early mortality. Right ventricular dysfunction, LVEF and NYHA class at presentation affect long-term survival. Concomitant CABG does not improve survival.
