Cardiac echinococcosis is an infrequently encountered entity, but with clinical suspicion and early diagnosis it can be successfully managed with good outcomes.

Anomalous origin of the right coronary artery from the main pulmonary artery (anomalous right coronary artery from pulmonary artery; ARCAPA) is a rare congenital anomaly. Here, we present an unusual case of anomalous right coronary artery from the main pulmonary artery with proximal intramural course.

Objective Myocardial protection is the most important in cardiac surgery. We compared our modified single-dose long-acting lignocaine-based blood cardioplegia with short-acting St Thomas 1 blood cardioplegia in patients undergoing single valve replacement.MethodsA total of 110 patients who underwent single (aortic or mitral) valve replacement surgery were enrolled. Patients were divided in two groups based on the cardioplegia solution used. In group 1 (56 patients), long-acting lignocaine based-blood cardioplegia solution was administered as a single dose while in group 2 (54 patients), standard St Thomas IB (short-acting blood-based cardioplegia solution) was administered and repeated every 20 minutes. All the patients were compared for preoperative baseline parameters, intraoperative and all the postoperative parameters.ResultsWe did not find any statistically significant difference in preoperative baseline parameters. Cardiopulmonary bypass time were 73.8±16.5 and 76.4±16.9 minutes (P=0.43) and cross clamp time were 58.9±10.3 and 66.3±11.2 minutes (P=0.23) in group 1 and group 2, respectively. Mean of maximum inotrope score was 6.3±2.52 and 6.1±2.13 (P=0.65) in group 1 and group 2, respectively. We also did not find any statistically significant difference in creatine-phosphokinase-MB (CPK-MB), Troponin-I levels, lactate level and cardiac functions postoperatively.Conclusion This study proves the safety and efficacy of long-acting lignocaine-based single-dose blood cardioplegia compared to the standard short-acting multi-dose blood cardioplegia in patients requiring the single valve replacement. Further studies need to be undertaken to establish this non-inferiority in situations of complex cardiac procedures especially in compromised patients.

Objective One of the major challenges faced in minimally invasive pediatric cardiac surgery is cannulation strategy for cardiopulmonary bypass. Central aortic cannulation through the same incision has been the usual strategy, but it has the disadvantage of cluttering of the operative field. We hereby present the results of femoral cannulation in minimally invasive pediatric cardiac surgery in terms of adequacy and safety. Methods From January 2013 to June 2016, 200 children (122 males) with mean ± SD age of 9.2 ± 4.51 years (median = 6 years, range = 3–18 years) and weight of 19.22 ± 8.49 kg (median = 15 kg, range = 8–45 kg) were operated for congenital cardiac defects through anterolateral thoracotomy. The most common diagnosis was atrial septal defect (144 patients). In all the patients, femoral artery and femoral vein were cannulated along with direct superior vena cava cannulation for institution of cardiopulmonary bypass. Results There were no deaths or any major complications related to femoral cannulation. Femoral artery cannulation provided adequate arterial inflow, whereas femoral vein with direct superior vena cava cannulation provided adequate venous return in all the patients. No patient required vacuum-assisted venous drainage. No patient required conversion to sternotomy or developed vascular, neurological complications. At discharge and at 1-year follow-up, both femoral artery and vein were patent without a significant stenosis on color Doppler ultrasonography in all the patients. At mean ± SD follow-up period of 30.63 ± 10.09 months, all the patients were doing well without any wound-related, neurological, or vascular complications. Conclusions Femoral arterial and venous cannulation is a feasible, reliable, and efficient method for institution of cardiopulmonary bypass in minimally invasive pediatric cardiac surgery.

BACKGROUND Right minithoracotomy and lower partial sternotomy are usual approaches for mini-invasive repair of congenital cardiac defects with a better cosmetic outcome. These approaches have been inadequate for repair of TOF due to limited exposure of the Right Ventricular Outflow Tract (RVOT) and pulmonary artery. Mini-left thoracotomy approach is sternal sparing and has the advantages of a cosmetic mini incision for surgical correction of patients with Tetralogy of Fallot (TOF). MATERIALS AND METHODS From December 2013 and January 2015, 27 paediatric patients (15 females) with mean age 13.2 years and mean weight 26.7 kg underwent intracardiac repair for TOF. A mini-left thoracotomy in third intercostal space involving a 3-5cm skin incision was used in all the patients. In 12 patients, pulmonary annulus was preserved and infundibular muscle resection was performed through RVOT. Fifteen patients received transannular patch. Ventricular Septal Defect (VSD) was closed through right ventriculotomy in all the patients.

Objective Blood cardioplegia, the gold-standard cardioprotective strategy, requires frequent dosing, resulting in hyperkalemia-induced myocardial edema. The aim of our study was to compare the efficacy and safety of a long-acting blood-based cardioplegia with physiological potassium levels versus the well-established cold blood St. Thomas' Hospital no. 1 cardioplegia solution in multivalve surgeries. Methods One hundred patients undergoing simultaneous elective aortic and mitral valve replacement ± tricuspid valve repair were randomized in two groups. In group 1, adenosine 12 mg was given via the aortic root after crossclamping, followed by a single dose of long-acting solution at 14℃ (30 mLċkg); in group 2, an initial 30 mLċkg of St. Thomas' cardioplegia at 14℃ was administered, followed by 15 mLċkg every 20 min. Duration of cardiopulmonary bypass, inotropic score, arrhythmias, ventilation time, and the levels of interleukin-6, creatinine kinase-MB, and troponin I were compared. Results Mean cardiopulmonary bypass and crossclamp times were 134.04 ± 36.12 vs. 154.34 ± 34.26 ( p = 0.004) and 110.37 ± 24.80 vs. 132.48 ± 31.68 min ( p = 0.002), respectively, in the long-acting and St. Thomas' groups. Cardiac index, creatinine kinase-MB and troponin I levels were comparable. Interleukin-6 levels post-bypass were 61.72 ± 15.33 and 75.44 ± 31.78 pgċmL ( p = 0.007) in the long-acting and St. Thomas' cardioplegia groups, respectively. Conclusions Single-dose long-acting cardioplegia gives a cardioprotective effect comparable to repeated doses of the well-established St. Thomas' Hospital no. 1 cold blood cardioplegia.

A Sinus of Valsalva Aneurysm can cause aortic insufficiency, coronary artery flow compromise, cardiac arrhythmia, or aneurysm rupture. There are different management plans available, ranging from open surgery to percutaneous device closure, but sometimes, device closure may be life-threatening. We report a case of ruptured Sinus of Valsalva Aneurysm in a 42-year-old woman, which was managed by percutaneous device closure that failed and required surgical removal of the device.
