Acute aortic dissection and pregnancy: Review and meta-analysis of incidence, presentation, and pathologic substrates.

Objectives: Pregnancy has been recognized as a predisposing factor for acute aortic dissection (AAD) although its occurrence is quite rare. Currently, no trial and few prospective studies exist about this catastrophic event. The present review and meta-analysis aims to update information on clinical presentation, potential risk factors, treatment, and outcome of acute dissection during pregnancy and puerperium.

Novel use of the AngioVac system.

The Vortex Medical AngioVac Cannula was employed in a 71-year-old man with a renal neoplasm with occlusion of the inferior vena cava and involvement of the right atrial cavity. Due to the presence of diffuse metastases, surgery was not indicated, and the AngioVac system was employed to remove the free-floating mobile atrial mass, thus minimizing the risk of pulmonary embolism and as a bioptic tool to allow a correct histological diagnosis. This novel use of this system may be advantageous in other similar cases.

Pulmonary and paradoxical coronary embolism with a patent foramen ovale.

Paradoxical embolism through a patent foramen ovale is a very unusual event considering that this cardiac anomaly may be present in as much as 26% of the general population. We describe the case of a 68-year-old man with a pulmonary and paradoxical coronary embolism in the presence of a patent foramen ovale. The finding of a worm-shaped thrombus though the atrial septum together with the risk of further embolization through the atrial septum prompted surgical treatment.

Transaxillary versus transaortic approach for transcatheter aortic valve implantation with CoreValve Revalving System: insights from multicenter experience.

Background: About one-third of candidates for transcatheter aortic valve implantation (TAVI) suffer from severe peripheral artery disease, making the routine femoral approach difficult or impossible. The aim was to compare the transaxillary (TAx) and the transaortic (TAo) route for TAVI with Medtronic CoreValve Revalving System (CRS).

Methods: Out of 1049 consecutive TAVI with 18F CRS, 242 (23%) were treated in 4 high-volume Italian Centre through TAx (61%) and TAo (39%).

Reduction in platelet count after aortic valve replacement: comparison of three bioprostheses.

Background And Aim Of The Study: Concerns have recently been raised regarding postoperative decreases in platelet count (PC) after aortic valve replacement (AVR) with the Sorin Freedom Solo (SFS) stentless bioprosthesis. In order to assess the relevance and the clinical impact of this phenomenon, variations in PC were monitored in patients with SFS valves, and compared to changes of PC in patients after AVR with two other bioprostheses, the Medtronic Mosaic (MOS) porcine valve and the Sorin Mitroflow (MIT) pericardial valve.

Methods: Three groups of patients (25 in each group) who had undergone AVR with a biological prosthesis were compared.

Aortopulmonary fistula after a modified Bentall procedure.

A 68-year-old man presented with aortic pseudoaneurysm and aortopulmonary fistula, due to dehiscence of the left coronary button anastomosis, at three months after surgery for acute aortic dissection using a composite conduit. At reoperation, the pulmonary trunk was repaired by direct suture and the coronary ostial anastomosis with single sutures, reinforced with pericardial pledgets from inside the aortic graft. Aortopulmonary fistula due to pseudoaneurysm formation is an extremely rare complication of operations on the proximal aorta.

Aortic valve replacement with the Medtronic Mosaic bioprosthesis: a 13-year follow-up.

Background: This study evaluated the long-term clinical performance of the Mosaic bioprosthesis (Medtronic Inc, Minneapolis, MN) after aortic valve replacement.

Methods: From 1995 to 2008, 178 patients (48 women; mean age, 74±6 years) had aortic valve replacement. Mean functional class was 2.

Unusual complication after aortic valve replacement with the Freedom Solo stentless bioprosthesis.

The case is presented of an unusual complication after aortic valve replacement with a Freedom Solo bioprosthesis. Excision of the aortic valve created a discontinuity of the aortic annulus that was missed intraoperatively and left uncorrected after supra-annular placement of the bioprosthesis; this created a pseudoaneurysm with direct communication to the pericardial cavity. When implanting the Freedom Solo bioprosthesis, care must be taken to exclude the presence of any aortic annular discontinuity.

Impact of treatment choice on the outcome of patients proposed for transcatheter aortic valve implantation.

Aims: Transcatheter aortic valve implantation (TAVI) is a new option for patients with severe aortic stenosis at high surgical risk. We compared the clinical outcome of patients referred for TAVI and subsequently treated with TAVI, surgical aortic valve replacement (SAVR), balloon aortic valvuloplasty (BAV), or medical management (MM).

Methods And Results: All consecutive patients (n=166, EuroSCORE 24.

Total calcification of an aortic homograft used as aortic root replacement.

A 66-year-old man presented with total calcification of a homograft used as aortic root replacement approximately 10 years previously. Reoperation consisted of complete dissection of the homograft and en-bloc replacement with a mechanical conduit. Despite careful dissection the right coronary ostium was disrupted requiring reconstruction by interposition of a saphenous vein segment.

Repair of coronary artery perforation following angioplasty using TachoSil patches.

Coronary perforation is a rare complication of percutaneous interventional procedures, occurring in 0.2-3% of procedures, which may require emergency coronary bypass surgery. We describe here an alternative method to deal with such complication, which proved effective in a patient with active bleeding from the left anterior descending (LAD) coronary artery.

Clinical outcome in patients with 19-mm and 21-mm St. Jude aortic prostheses: comparison at long-term follow-up.

Background: Small-sized prostheses for aortic valve replacement may result in residual left ventricular outflow tract obstruction. Aim of the study was to verify whether implantation of 19-mm versus 21-mm St. Jude Medical standard prostheses (St.
