Primary percutaneous coronary intervention (PPCI) remains the gold-standard treatment for ST- elevation myocardial infarction (STEMI). Femoral arterial access for the procedure may be an ideal option in patients who are haemodynamically unwell. However, it is associated with rare, but life- threatening, complications such as perforation, leading to retroperitoneal haemorrhage. We present the case of a man in his 50s, admitted with cardiac arrest secondary to inferolateral STEMI. Successful PPCI was performed via right femoral artery, with access gained under ultrasound guidance. However, the patient deteriorated and was diagnosed to have a retroperitoneal haematoma secondary to femoral artery perforation. Additional arterial access via left brachial artery was obtained, and a covered stent was deployed successfully in the right femoral artery with satisfactory haemostasis. The patient recovered successfully and was discharged two weeks later. Early recognition of such complications is imperative to adequate management and percutaneous treatment is a viable option for such situations, in comparison with open surgical repair.

Interventional cardiology is on the cusp of a significant transformation as we approach 2050, driven by emerging trends and groundbreaking technological innovations. This mini review explores the pivotal developments shaping the field, focusing on three key areas: Emerging Trends in Interventional Cardiology, Technological Innovations: The Next Frontier, and the Future Era of Intervention Cardiology from 2024 to 2050. Emerging trends, including advancements in imaging and artificial intelligence, are revolutionizing diagnosis and treatment, allowing for more precise and personalized interventions. Technological innovations, such as robotic-assisted procedures and bioresorbable stents, are redefining the landscape, enhancing procedural accuracy, and expanding access to care through remote interventions. Looking ahead to 2050, we anticipate a future where interventional cardiology is increasingly driven by minimally invasive techniques, AI-driven decision-making, and personalized medicine, offering unprecedented improvements in patient outcomes and reshaping the way cardiovascular diseases are managed.

BACKGROUND: Myocardial ischemia can occur due to several causes, which result in an imbalance between the supply and demand of oxygen to cardiac muscles. One potential reason for this condition is the overwork of the heart due to hyperstimulated thyroid function.
METHODS: The patient was a 36-year-old woman who presented with left-sided chest pain, dyspnea, palpitation, and tremor. The initial evaluation showed evidence of myocardial ischemia (positive high-sensitivity troponin) caused by a hyperactive thyroid gland. The treatment for myocardial infarction, along with anti-thyroid medications, improved the patient\'s condition and subsided the symptoms. The coronary angiography revealed no pathologic finding, and the hypokinetic left ventricle, observed in the first echocardiogram, was resolved. The patient was discharged with an excellent clinical condition, and after the 4-month taking of a calcium channel blocker and tapering carbimazole, the thyroid function became normal, and her symptoms resolved completely.
CONCLUSIONS: Patients without evident risk factors for ischemic heart disease, such as non-diabetic, nonsmoker, and young individuals who presented with acute coronary syndrome, should be evaluated for a potential background reason for the imbalance between the oxygen demand and supply of the myocardium. The presence of palpitation, weight loss, tremors, insomnia, and anxiousness, along with ischemic signs, should make the physician think about the probability of the hyperthyroid-induced cardiovascular disorder.
UNASSIGNED: The initial presentation of hyperthyroidism might be accompanied by severe cardiac symptoms. When the demographic features are not aligned with usual ischemic heart disease, other probable symptoms and signs should be investigated, and thyroid function should be checked. The control of thyroid hyperactivity would result in the resolution of both cardiac and non-cardiac symptoms.

Acute viral myocarditis and hyperthyroidism can present with acute coronary syndrome. However, the link between hyperthyroidism and myocarditis has hardly been explored apart from a small collection of published case reports. We report a case where a patient presents with severe chest pain and was found to have concomitant severe coronary vasospasm and acute myocarditis and was diagnosed with Graves\' disease.

Renal denervation may be indicated in patients with treatment-resistant essential hypertension to decrease sympathetic nervous activity and optimise blood pressure. We present the case of a woman in her 50s with long-standing essential hypertension, a previous transient ischaemic attack, obesity and a family history of cardiovascular disease, who presented with persistent 24-hour ambulatory hypertension despite ongoing lifestyle modifications and being on five antihypertensive agents with no evidence of an alternative primary aetiology. She had intermittent palpitations and blurring of vision alongside evidence of left ventricular hypertrophy on a CT scan. She underwent renal denervation, following which, not only was she able to cease all antihypertensive therapy but managed to maintain optimised blood pressure with subsequent reversal of left ventricular hypertrophy. Trials have demonstrated modest but inconsistent reductions in blood pressure whereas our case represents a \'super-response\' likely due to a higher number of circumferential ablations in comparison to previous studies.

A middle-aged man presented with inferior wall ST-elevation myocardial infarction and underwent primary percutaneous coronary intervention with tirofiban administered due to extensive thrombus. He developed sudden-onset dyspnoea, bilateral crepitations, haemoptysis, desaturation and hypotension an hour after starting tirofiban infusion. The tirofiban, antiplatelet medications and heparin were stopped immediately. Chest X-ray showed patchy opacities in the left upper, middle and lower zones. High-resolution CT showed confluent areas of consolidation with surrounding ground glass opacities and interlobular septal thickening (crazy pavement appearance) representing diffuse alveolar haemorrhage (DAH). He was managed with inotropes, non-invasive ventilation and intravenous furosemide. He was asymptomatic with complete resolution of lung opacities in chest X-ray done 2 months follow-up. DAH is a rare but potentially life-threatening complication which is often misidentified with other respiratory syndromes. Treatment includes stopping tirofiban and anticoagulant medication, blood transfusion, and institution of mechanical ventilation.

Renal denervation as an option for difficult to treat hypertension has been a concept for several decades, with recent U.S. FDA approval of new, minimally invasive devices. However, while renal denervation has the potential to improve hypertension management, several challenges require consideration prior to widespread adoption. The effect relative to sham control is modest, and generally similar to addition of a single blood pressure lowering medication. It is possible that with additional technique refinement greater effects may be possible. Key factors to consider beyond the direction, strengths, and limitations of the renal denervation technologies themselves, are an understanding of patient groups that derive greatest benefit and phenotypes or biomarkers that predict greater response. This review provides an update on these challenges in addition to the current state and future of renal denervation within the context of hypertension management and treatment.

In patients with anomalous origin of the left main coronary artery, accurate classification is essential for effective management. Despite surgical refusal, successful stenting and medication can lead to favorable outcomes. Regular monitoring ensures ongoing cardiac health.
UNASSIGNED: Coronary artery anomalies, including anomalous origin of the left main coronary artery from the right sinus of Valsalva, are rare occurrences with varying clinical significance. Accurate classification of these anomalies is crucial for determining their implications and guiding management. A 50-year-old man presented with chest pain and was diagnosed with an anomalous origin of the left main coronary artery. Despite refusing surgery, successful stenting and medication led to a favorable outcome. Regular monitoring is scheduled. Accurate classification of coronary anomalies, such as the left main coronary artery anomaly described, is vital for effective management. Even when surgical intervention is declined, alternative treatments, such as stenting, can be successful. Regular monitoring ensures ongoing cardiac health.

Pseudocoarctation of the aorta (PCoA) is a rare congenital anomaly characterized by the abnormal kinking of the thoracic aorta. It is often incidentally diagnosed but gained clinical significance due to its propensity to develop aortic aneurysm and rupture. A standard diagnostic and treatment algorithm for PCoA is lacking, and also, the natural history of the disease is not well studied. We present here a case of PCoA with a fusiform aneurysm of the thoracic aorta to emphasize the need to differentiate it from true coarctation and to rule out associated complications.
