Successful emergent repair of a subacute left ventricular free wall rupture after acute inferoposterolateral myocardial infarction

BACKGROUND: Myocardial rupture is an important and catastrophic complication of acute myocardial infarction. A dramatic form of this complication is a left ventricular free wall rupture (LVFWR). CASE PRESENTATION: A 70-year-old man with acute inferoposterolateral myocardial infarction and single-vessel coronary artery disease underwent emergency percutaneous coronary intervention (PCI). The circumflex coronary artery was successfully stented with a drug-eluting stent. Fifty days after PCI the patient experienced progressive fatigue and chest pain with haemodynamic instability. Transthoracic echocardiography showed a covered LVFWR of the lateral wall. The patient underwent successful emergent surgical repair of the LVFWR. CONCLUSIONS: In the current era of swift PCI, mechanical complications of acute myocardial infarction, such as LVFWR, are rare. The consequences, however, are haemodynamic deterioration and imminent death. This rare diagnosis should always be considered when new cardiovascular symptoms or haemodynamic instability develop after myocardial infarction, even beyond one month after the initial event. Timely diagnosis and emergency surgery are required for successful treatment of this devastating complication

Thoracotomy Versus Sternotomy for Patent Ductus Arteriosus Closure in Preterm Neonates

Background: To date, a posterolateral thoracotomy approach is considered the gold standard for surgical closure of patent ductus arteriosus (PDA), also in preterm neonates. However, a posterolateral thoracotomy approach can induce post-thoracotomy lung injury of the immature and vulnerable lungs of preterm neonates. Therefore, this study aims to compare a posterolateral thoracotomy and median sternotomy for surgical closure of PDA in preterm neonates. Methods: Between September 2010 and November 2014, both surgical approaches were used to treat a symptomatic PDA in very and extremely preterm neonates. The hospital records of all these neonates were retrospectively reviewed to assess all-cause mortality and postoperative morbidity in both groups. Results: Despite comparable preoperative patient profiles, the postoperative pulmonary complication rate was significantly lower in the median sternotomy group (52.9% vs 94.7%; P = .006). Moreover, significantly lower mean airway pressures (MAPs) were seen in the median sternotomy group directly after surgery (ΔMAP median [interquartile range], 0.00 [2.13] vs 0.80 [1.67] cmH2O; P = .025). Postoperative blood transfusion (median [interquartile range], 20 [14] vs 17 [16] mL; P = .661) rates did not differ between both approaches. In addition, Kaplan-Meier survival analysis demonstrated no statistically significant differences between both groups. Conclusions: In our experience, a median sternotomy approach for surgical PDA closure is at least noninferior to a posterolateral thoracotomy approach. Given the lower postoperative pulmonary complication rate and lower postoperative MAPs directly after surgery, the median sternotomy approach may be considered superior for preterm neonates with immature and vulnerable lungs
