RESUMO
Penetrating cardiac injury is rare and frequently not survivable. Significant haemorrhage resulting in cardiac tamponade commonly ensues. Such cardiac tamponade is a clear clinical, radiological and sonographic indicator of significant underlying injury. In the absence of cardiac tamponade, diagnosis can be more challenging. In this case of a 26-year old sailor stabbed at sea, a significant pericardial effusion and cardiac tamponade did not occur despite an injury transversing the pericardium. Instead, the pericardial haemorrhage drained into the left pleural cavity resulting in a haemothorax. This case is notable due to a favourable outcome despite a delay in diagnosis due to a lack of pericardial effusion, a concomitant cerebrovascular event and a long delay from injury to appropriate medical treatment in the presence of a penetrating cardiac wound deep enough to cause a muscular ventricular septal defect and lacerate a primary chordae of the anterior mitral leaflet.

We present a case of a 44-year-old woman who presented with cough, pleuritic chest pain and fever leading to a diagnosis of pneumonia±pulmonary embolism. She had a history of familial hypertrophic obstructive cardiomyopathy (HOCM), for which an automated implantable cardioverter defibrillator (AICD) had been implanted, and a subsequent superior vena cava (SVC) thrombus, for which she was anticoagulated with warfarin. On admission, blood cultures grew a coagulase-negative Staphylococcus. CT pulmonary angiogram and transoesophageal echocardiography (TOE) were performed and revealed large vegetations adherent to the AICD leads with complete occlusion of the SVC. The infected leads were the source of sepsis. Open surgery was planned. For cardiopulmonary bypass, the venous cannula was inserted in the inferior vena cava (IVC) and a completely bloodless field was obtained in the right atrium allowing for the extraction of the AICD leads completely, along with the adherent vegetations from within.

Unicuspid aortic valve (UAV) is a rare congenital anomaly typically affecting patients in their fourth and fifth decades and presenting with signs of heart failure. Our case is one of a previously asymptomatic teenage girl with a UAV, who presented with cardiac arrest and was successfully treated. Only two other similar cases have been reported in the literature, both were of slightly older male patients. Our case highlights the morbidity associated with the anomaly supporting the need for careful assessment of the valve in cases where UAV is suspected.

Malignant cardiac tumours occurring on the left side are vanishingly rare entities. We describe a case of a 73-year-old male who underwent surgery for a left-sided cardiac tumour following initial presentation with transient ischaemic attacks. In addition to the unusual presentation and subsequent metastatic pattern to the femur, the tumour's pathological diagnosis was that of an epithelioid variant of an angiosarcoma which has not been previously described in this anatomical location.
