• Article: Primary right atrial angiosarcoma.

  Kirkpatrick Santo, Uday Dandekar
  [show abstract] [hide abstract]
  ABSTRACT: A rare case of right atrial angiosarcoma is described in a 55-year-old man who was admitted with acute chest pain. Electrocardiography, cardiac enzymes, and chest radiography were negative. His pain settled and he was discharged, but readmitted 15 days later with clinical features of cardiac tamponade. Computed tomography demonstrated a large pericardial effusion. Emergency surgery was performed to excise a right atrial tumor, which histology confirmed to be an angiosarcoma.

• Article: Near-infrared spectroscopy: an important monitoring tool during hybrid aortic arch replacement.

  Kirkpatrick C Santo, Alejandro Barrios, Uday Dandekar, Peter Riley, Peter Guest, Robert S Bonser
  [show abstract] [hide abstract]
  ABSTRACT: Near-infrared spectroscopy can be helpful for monitoring the adequacy of cerebral perfusion during cardiovascular surgery. We report changes seen in regional oxygen saturation due to intraoperative thrombosis of the left common carotid artery graft during hybrid aortic arch replacement for traumatic aortic injury.

  Article: Isolated severe ischemic tricuspid regurgitation: successful surgical repair.

  Uday Dandekar, Anand Sachithanandan, Maninder Kalkat, Paul Ridley, Christopher M R Satur
  [show abstract] [hide abstract]
  ABSTRACT: Tricuspid regurgitation (TR) is a common association of left-sided valvular lesions that is occasionally seen with ischemic heart disease. However, isolated ischemic TR requiring surgical intervention is extremely rare, with very few reported cases. The case is presented of a 59-year-old woman who, after extensive non-cardiac investigations, was eventually diagnosed with severe functional TR due to chronic myocardial ischemia. The patient underwent successful surgical treatment.

• Article: Fatal early acute thrombosis of mechanical mitral prosthesis.

  Uday Dandekar, Maninder Kalkat, Christopher Smallpeice
  [show abstract] [hide abstract]
  ABSTRACT: To report a rare case of fatal early acute thrombosis of mechanical mitral prosthesis. A 62-year-old lady, who underwent closed mitral valvotomy for rheumatic heart disease 19 years ago, presented with Canadian Cardiovascular Society Class II angina and New York Heart Association Class III dyspnoea. Investigations including echocardiogram and cardiac catheterisation revealed mixed mitral valve disease. She had severe pulmonary artery hypertension with pulmonary artery wedge pressure of 35 mm of mercury. Significant stenosis in the midportion of dominant right coronary artery was also demonstrated. She underwent mitral valve replacement using mechanical tilting disc prosthesis, DeVega tricuspid annuloplasty and saphenous vein bypass graft to the distal right coronary artery. After having made satisfactory early postoperative progress, she suffered an asystolic cardiac arrest about 26 h postoperatively. The patient succumbed despite all resuscitative measures. Autopsy revealed an adherent thrombus occluding the atrial surface of the minor orifice of mechanical prosthesis, which prevented the valve from functioning. To the best of our knowledge, this is the first case of prosthetic valve thrombosis (PVT) occurring on the first postoperative day in a patient with a mechanical valve prosthesis, without any circulatory assist device.

• Article: Transfusion related acute lung injury in cardiac surgery.

  [show abstract] [hide abstract]
  ABSTRACT: Transfusion related acute lung injury (TRALI) is an uncommon complication following administration of blood products. It is often difficult to differentiate from other commoner causes of cardio-respiratory instability. However, prompt diagnosis and management is associated with favorable outcome.

• Article: Left ventricular aneurysmectomy: tailored scar excision and linear closure.

  [show abstract] [hide abstract]
  ABSTRACT: Coronary artery bypass surgery with or without aneurysmectomy is used to treat patients with left ventricular aneurysm. There is debate about patient selection and the appropriate surgical technique. We analyzed the results of 102 consecutive patients who underwent left ventricular aneurysmectomy and reconstruction using a modified linear closure technique between 1992 and 2003. The mean age was 62 years, 81% of the patients were male, and 47% had an ejection fraction < 35%. The locations of the left ventricular aneurysms were anteroapical (75%), apical (21%), and posteroinferior (4%); 23% contained thrombi. Additional procedures included aortic valve replacement in 4, mitral valve repair in 1, and coronary bypass grafting in 98 patients; 3 underwent isolated repair of left ventricular aneurysm. Hospital mortality was 7% and long-term survival was 76% at a mean follow-up of 39 months. Most patients improved symptomatically postoperatively. Left ventricular aneurysm repair with tailored scar excision and a modified closure technique is associated with acceptable mortality and long-term survival.

• Article: Saphenous vein patch plasty to correct saphenous graft and aortotomy mismatch.

  Uday Dandekar, Maninder S Kalkat, Paul Ridley
  [show abstract] [hide abstract]
  ABSTRACT: Mismatch of aortotomy and saphenous vein graft size occasionally occurs and can compromise the contour of the anastomosis thereby jeopardising its patency. We describe an alternative technique of saphenous vein patch plasty to overcome this complication by giving a more desirable hooded contour to the anastomosis. This results in improved graft patency, hemostasis and clinical outcome.

• Article: Heparin induced thrombocytopenia type II complicating coronary artery bypass surgery: a tale of caution.

  Uday Dandekar, Jonathan Young, Maninder Kalkat, Christopher M R Satur
  [show abstract] [hide abstract]
  ABSTRACT: To highlight an uncommon problem of heparin induced thrombocytopenia after coronary artery bypass operation. We report the case of a 59-year-old man who suffered severe type II heparin induced thrombocytopenia (HIT) after coronary artery bypass operation. He experienced extensive skin necrosis at sites of saphenous vein harvesting, which progressed to cause soft tissue necrosis of both feet. He also exhibited secondary clinical features arising from pulmonary, hepatic and renal dysfunction suggestive of extensive venous thrombosis. Primary treatment of the haematological disorder was achieved by discontinuation of all forms of heparin and the administration of a heparinoid intravenously. Secondary treatment included forefoot amputations and skin grafting. Though the patient suffered a protracted period of recovery he was discharged home well. We have reported this complex case in order to familiarise cardiothoracic surgeons with the extreme characteristics of type II HIT and to emphasise that early diagnosis and treatment will facilitate a successful outcome.

• Article: Aortic valve replacement with simultaneous chest wall reconstruction for radiation-induced sarcoma.

  ABSTRACT: Sarcomas, a rare complication of radiotherapy for breast carcinoma, have a poor prognosis. We describe a lady with previous mantle radiotherapy exposure, who developed a radiation-induced chest wall sarcoma. She underwent simultaneous aortic valve replacement (AVR) for severe aortic stenosis and excision of the sarcoma. Chest wall reconstruction was achieved with a composite marlex cement plate and a pedicled latissimus dorsi muscle flap.
