Quadricuspid Aortic Valve Repair Facilitated by Geometric Ring Annuloplasty.

Quadricuspid aortic valve (QAV) is a rare congenital anomaly often associated with aortic insufficiency. The exact anatomy of QAV is variable, and most cases have undergone aortic valve replacement. With the recognition that aortic valve repair achieves superior patient outcomes as compared to replacement, a systematic approach to autologous reconstruction of QAV is needed. This article reports 2 cases having successful repair utilizing geometric aortic annuloplasty rings, and describes a proposed scheme for repairing most QAV defects, based on relative leaflet and commissural characteristics. Using either tri-leaflet or bicuspid ring annuloplasty, the normal sub-commissural triangles can be remodeled into a 120° or 180° configuration, respectively, and then the leaflets can be sutured and plicated to fit annular geometry. With this approach, most quadricuspid valves potentially could undergo autologous reconstruction.

Coronary Artery Bypass Grafting in a Patient with Dextrocardia with Situs Inversus.

Dextrocardia involves embryologic malformations leading to a right hemithorax heart with rightward apex. Situs inversus encompasses all viscera in mirrored position. A 76-year-old male with dextrocardia with situs inversus presented for coronary artery bypass grafting due to a non-ST elevation myocardial infarction. Management was altered accordingly. Electrocardiography leads and defibrillator pads were reversed. A left internal jugular vein central venous catheter provided direct access to the right atrium. Transesophageal echocardiography confirmation of aortic and venous cannulation required turning the probe right for the right-sided aorta and left for liver visualization, respectively. Proactive surgical and anesthetic management was imperative for the successful and uneventful outcome for this patient.

Iatrogenic Superior Vena Cava Syndrome after Cardiopulmonary Bypass Diagnosed by Intraoperative Echocardiography.

A 73-year-old female patient presented for mitral valve replacement and coronary artery bypass grafting secondary to multivessel coronary disease and severe mitral valve regurgitation with moderate stenosis. After bypass, the patient developed refractory hypotension with decreased biventricular volume and elevated central venous pressure (CVP). Transesophageal echocardiography (TEE) was utilized to make the diagnosis of acute intraoperative superior vena cava (SVC) syndrome. The SVC cannulation site was revised, resulting in resolution of the hypotension and a decrease in the CVP. Intraoperative TEE was vital in recognizing, managing, and ultimately repairing the acute intraoperative SVC stenosis.
