Embolization of Patent Foramen Ovale Closure Device-Rare Complication and Unique Management Approach.

Percutaneous closure of the patent foramen ovale (PFO) is generally regarded as a safe and effective procedure, indicated in patients with a prior PFO-associated stroke. While it is highly safe, rarely, it could be accompanied by a migration of the device, mainly caused by the interplay of a specific PFO morphology and inappropriate device sizing. Herein, we outline a seldom-observed complication of an unintentional detachment of the PFO closure device during implantation, leading to its migration into the abdominal aorta, and a unique management approach. Due to the inability to recapture the occluder with a snare, which is considered to be a mainstay of endovascular retrieval methods, two coronary guidewires were maneuvered through the mesh of the occluder and then captured with a snare proximally to the occluder. This innovative dual-wire-snare system was carefully pulled to the common femoral artery, a position deemed suitable for surgical extraction via arteriotomy, which was achieved successfully.

Himalayan P wave in a patient admitted for cardiac surgery.

Giant or Himalayan P waves are tall and peaked, the most prominent in lead II, and generally indicate enlargement of the right atrium. It has been rarely seen in clinical practice. The mechanism of Himalayan P wave formation is most likely related with prolonged conduction of electrical impulses through the enlarged right atrium. We describe the case of a patient with Himalayan P wave admitted for cardiac surgery.

Significance of Galectin-3 and N-terminal pro b-type natriuretic peptide in the prediction of atrial fibrillation after cardiac surgery.

Background: Post-operative atrial fibrillation (POAF) is a frequent complication after cardiac surgery. It is associated with prolonged hospital stay, increased morbidity, mortality rate and economic costs. The aim of the study was to determine the association between the values of Galectin3 and N-terminal pro-B-type natriuretic peptide (NTproBNP) with POAF after cardiac surgery. Methods: A prospective study enrolled patients aged 18-85 years old admitted due to elective coronary artery bypass graft surgery (CABG) or CABG + aortic valve replacement. The plasma Galectin-3 and NT-proBNP levels were measured one day before surgery postoperative days 1 and 7. Results: The study included a total of 103 patients. POAF was registered in 45 patients. The mean age of patients in whom POAF occurred was 68.8 years, while other patients' mean age was 65.5 years (p=0.028). Patients with POAF did not differ from the group without POAF in the values of Galectin-3 and NT-proBNP preoperatively as well as on the first and seventh postoperative days. Changes in Galectin-3 levels on the first postoperative day had statistically significant value for predicting POAF (AUC=0.627 0.509-0.745 , p<0.05). Decrease in Galectin-3 level con centration on the first postoperative day over 17% increases the risk of developing AF. Conclusions: Preoperative values of Galectin-3 and NTproBNP are not associated with POAF development after cardiac surgery.

Surgical treatment of intramural hematoma of the ascending aorta.

INTRODUCTION: Intramural hematoma of the aorta presents potentially fatal condition developing as a result of a vasa vasorum rupture. It is a major risk factor for developing a frank aortic dissection. CASE OUTLINE: A 65-year-old woman was admitted to our clinic for the second time, after her symptoms of chest pain and vertigo (with no electrocardiographic signs of myocardial infarction) hadn't disappeared after several months of medicament treatment (indicated in the first hospitalization). Computed tomography arteriography of the aorta showed no sign of acute aortic dissection, but revealed a contrast depo in the aortic wall of 8 x 14 mm dimensions, with no extravasation of contrast. Also, massive pericardial effusion was observed (10-30 mm in thickness). Transesophageal echocardiography confirmed these findings completely. The patient underwent surgery, in which plaque exulceration was detected on the convex side of the ascending aorta, 3 cm above the aortic valve, 1 cm in diameter, with no signs of intimal tear. A resection of the ascending aorta was performed, and the aorta was reconstructed with a 30 mm Dacron tube graft. The patient was discharged on the 14th postoperative day with satisfactory results. CONCLUSION: Intramural hematoma is not a common event, but it is potentially a fatal one. Open surgery in patients with an intramural hematoma is an effective treatment strategy, although percutaneous endovascular treatment options are being described.
