ABSTRACT
We describe a novel technical modification for reoperative aortic valve replacement in destructive recurrent prosthetic aortic valve endocarditis. We encountered complex anatomy in a previously operated aortic root wherein the aortic annulus and the right coronary sinus of Valsalva were destroyed. This precluded secure suture placement. We modified a composite mechanical Valsalva conduit to create a separate sinus of Valsalva left in continuity with the mechanical valve. This approach allowed us to exclude the infected right sinus of Valsalva and the corresponding aortic annulus.
ABSTRACT
We present a unique case of aggressive symptomatic constrictive pericarditis within one month following off pump coronary artery bypass grafting surgery. The patient had a medical history of Hodgkin's lymphoma treated with radiotherapy and chemotherapy 20 years ago. Investigations confirmed constrictive pericardium with patent grafts and good biventricular function. Pericardiectomy was successful with remarkable recovery of symptoms.
ABSTRACT
We present the case of a 28 year-old lady with a history of intravenous drug use who presented to our institution with symptomatic right heart failure secondary to tricuspid valve regurgitation. She presented with infective endocarditis leading to dyspnoea and peripheral oedema secondary to torrential tricuspid regurgitation. Transthoracic echocardiography confirmed right ventricular dysfunction and congestive hepatomegaly. Intra-operatively findings an infected and destroyed anterior leaflet of the tricuspid valve with posterior leaflet prolapse was found to cause severe tricuspid regurgitation. She had complex tricuspid valve reconstruction using anterior leaflet reconstruction using Admedus Cardiocel™ patch, posterior leaflet prolapse correction and commissural reduction with a McGoon imbrication and annuloplasty ring to stabilize the repair. This case demonstrates the importance of reconstructive tricuspid valve surgery in the setting of infective endocarditis. Furthermore, this case demonstrates the possibility of anterior leaflet excision and reconstruction with an excellent durable functional result.
ABSTRACT
Removal of tunnelled central venous catheters can become complex if left in situ for a prolonged period. We report a challenging case of a stuck tunnelled haemodialysis catheter, which required sternotomy with cardio-pulmonary bypass for retrieval. A 47-year-old female had failed attempts to remove the venous limb of a Tessio line on the ward. A cut down on the internal jugular vein and division of the fibrin sheath failed to release it. Synchronous traction was applied via a snare inserted through a femoral approach. On table trans-oesophageal echocardiogram showed the tip of the catheter traversing the tricuspid valve. At sternotomy with cardio-pulmonary bypass, the tip of the catheter was found attached to the septal leaflet of the tricuspid valve requiring release and repair. The management of stuck line has potential serious complications. Prophylactic catheter exchange should be considered to avoid complications.
ABSTRACT
A 19-year-old primigravida, with a history of mechanical mitral prosthesis at the age of six years following previous repair of an atrioventricular septal defect, presented at 26 weeks' gestation with cardiogenic shock secondary to obstruction of the mitral prosthesis. She underwent successful emergency redo mitral valve replacement and caesarean section. At operation the prosthesis was found to be virtually completely obstructed with pannus. Both mother and baby had an excellent outcome following surgery. The case report is presented with a brief review of the literature.
