    BACKGROUND: Intramyocardial dissecting haematoma is a rare complication of myocardial infarction (MI) associated with high mortality rates. Studies and research of this occurrence are limited largely to isolated case reports or case series.

    CASE SUMMARY: We report a case of late presenting MI, where on initial echocardiogram had what was thought to be an intraventricular clot. However, upon further evaluation, the patient actually had an intramyocardial haematoma, with the supporting echocardiographic features to distinguish it from typical left ventricular (LV) clot. While this prevented the patient from receiving otherwise unnecessary anticoagulation, this diagnosis also put him at a much higher risk of mortality. Despite exhaustive medical and supportive management, death as consequence of pump failure occurred after 2 weeks.

    DISCUSSION: This report highlights the features seen on echocardiography which support the diagnosis of an intramyocardial haematoma rather than an LV clot, notably the various acoustic densities, a well visualized myocardial dissecting tear leading into a neocavity filled with blood, and an independent endocardial layer seen above the haematoma. Based on this report, we wish to highlight the importance of differentiating intramyocardial haematomas from intraventricular clots in patients with recent MI.

    Introduction: As a causal organism in infective endocarditis, Burkholderia pseudomallei is rare. Burkholderia pseudomallei is intrinsically resistant to aminoglycosides but a gentamicin-susceptible strain was discovered in Sarawak, Malaysian Borneo in 2010. We report the first occurrence of infective endocarditis due to the gentamicin-susceptible strain of B. pseudomallei.

    Case presentation: A 29-year-old man presented with pneumonia and melioidosis septicaemia. His condition was complicated with infective endocarditis and septic emboli to the brain. Despite difficulties in reaching a diagnosis, the patient was successfully treated using intravenous gentamicin and ceftazidime and was discharged well.

    Discussion: The role of gentamicin in the treatment of the gentamicin-susceptible strain of B. pseudomallei remains unclear.

    Background : Sinus of Valsalva aneurysm (SoVA) is a rare anomaly and can be divided into acquired and congenital forms, the latter being commonly associated with ventricular septal defects (VSDs). Rupture is a catastrophic complication with high mortality without urgent surgical intervention. We would like to highlight the use of echocardiography in an emergency setting for diagnosis and surgical intervention in a critically ill patient.

    Case summary : We report a 27-year-old female with history of conservatively managed VSD known since childhood. She presented with acute decompensated cardiac failure requiring intubation and inotropic support. Bedside echocardiography performed in the emergency department suggested a ruptured SoVA at the right coronary cusp with underlying supracristal VSD. Despite the patient being critically ill with multi-organ failure, surgery was performed as it was the patient's best chance for survival. Intraoperative findings tallied with the early echocardiographic results. She recovered gradually and was eventually discharged despite a stormy post-operative period.

    Discussion : This case report highlights the importance of prompt recognition of SoVA rupture by using bedside echocardiography. Surgical intervention needs to be early despite ongoing sepsis in view of acute mechanical failure. This case was unique as it illustrates a successful management of an acutely ill patient with multi-organ failure through early diagnosis, intensive perioperative stabilization, and surgical intervention.

    Background: Intravascular lithotripsy is a new method used to treat calcified coronary lesions (CCLs). Percutaneous coronary intervention of CCLs has conventionally been classified as a complex procedure. In the majority of calcified cases, atherectomy is required for sufficient plaque modification prior to stent implantation. Intravascular lithotripsy has been shown to be safe and effective in clinical trials, but as worldwide usage increases, cases of complications are beginning to emerge.

    Case summary: We describe a 71-year-old woman, who after an episode of non-ST-elevation acute coronary syndrome underwent coronary angiography. The culprit vessel was identified to be a severely stenosed left anterior descending artery which was also heavily calcified and tortuous. Intravascular lithotripsy (IVL) was employed for calcium modification prior to stent implantation, but the IVL balloon ruptured during shockwave lithotripsy, resulting in coronary artery dissection. Subsequent management steps and stent deployment resulted in favourable angiographic results. Our findings are further detailed on optical coherence tomography, demonstrating certain features which might predispose to IVL balloon rupture.

    Discussion: We discuss the mechanism of action during intravascular lithotripsy, and how the shockwaves from the lithotripter modify calcified lesions, whilst keeping soft tissue unharmed. Results from clinical trials and multiple real-world studies have shown that complication rates are low. This case report aims to illustrate how the rupture of an intravascular lithotripsy balloon can result in coronary artery dissection. Optical coherence tomography can help in identifying potential anatomical features which may precede such complications.

    BACKGROUND: Familial hypercholesterolaemia (FH) is an autosomal dominant genetic condition predominantly caused by the low-density lipoprotein receptor (LDLR) gene mutation.

    CASE SUMMARY: This is the case of a 54-year-old Malay woman with genetically confirmed FH complicated by premature coronary artery disease (PCAD). She was clinically diagnosed in primary care at 52 years old, fulfilling the Simon Broome Criteria (possible FH), Dutch Lipid Clinic Criteria (score of 8: probable FH), and Familial Hypercholesterolaemia Case Ascertainment Tool (relative risk score of 9.51). Subsequently, she was confirmed to have a heterozygous LDLR c.190+4A>T intron 2 pathogenic variant at the age of 53 years. She was known to have hypercholesterolaemia and was treated with statin since the age of 25. However, the lipid-lowering agent was not intensified to achieve the recommended treatment target. The delayed FH diagnosis has caused this patient to have PCAD and percutaneous coronary intervention (PCI) at the age of 29 years and a second PCI at the age of 49 years. She also has a very strong family history of hypercholesterolaemia and PCAD, where seven out of eight of her siblings were affected. Despite this, FH was not diagnosed early, and cascade screening of family members was not conducted, resulting in a missed opportunity to prevent PCAD.

    DISCUSSION: Familial hypercholesterolaemia can be clinically diagnosed in primary care to identify those who may require genetic testing. Multidisciplinary care focuses on improving identification, cascade screening, and management of FH, which is vital to improving prognosis and ultimately preventing PCAD.
