Device closure of PDA with PAH is feasible, safe in all age groups. Temporary PDA occlusion with device is effective and time saving for evaluating pulmonary vascular reactivity. Device embolization in aorta is higher with severe PAH. Novel method of retrieval is effective.

SUMMARYWe describe a case of previously healthy 72-year-old man, who presented with rest angina. The ECG revealed sinus rhythm, biphasic T waves with preserved R waves in V1-V4 precordial leads. Subsequent evaluation revealed the normal serum cardiac marker levels and echocardiography with the coronary angiography showing a critical lesion in the proximal left anterior descending artery. Thus it was diagnosed as Wellens' syndrome. In our case, we highlight the subtle though classical ECG findings of Wellens' syndrome and its specific angiographic correlation. It can be of vital importance to identify these changes and intervene in time appropriately so as to avoid the development of myocardial infarction that carries a substantial morbidity and mortality. Important aspects of diagnosis and management have also been reviewed. BACKGROUND

SUMMARYMycotic cerebral aneurysm is a rare and potentially fatal complication of infective endocarditis. A young man was diagnosed with culture negative infective endocarditis of mitral valve with cerebral aneurysm. The patient was started on conservative management, but he died owing to intracerebral haemorrhage. In the absence of large randomised trials, there is a lack of consensus regarding the management of unruptured aneurysms. Since mycotic aneurysms are known to resolve or decrease in size with antimicrobial therapy, several institutions advice the conservative approach. A few case reports like the present case have shown that the risk of aneurysmal rupture and death is considerably high with the conservative approach. Endovascular therapy has shown to reduce the mortality in this subgroup. These patients should be managed aggressively with endovascular or surgical procedure along with antimicrobial therapy. BACKGROUND

The occurrence of an acute myocardial infarction (MI) following a scorpion sting has been very rarely reported in the previous literature. Possible pathogenetic mechanisms include severe hypotension due to hypovolaemic shock and coronary spasm with subsequent thrombosis of coronary vessels developed after the release of vasoactive, inflammatory and thrombogenic substances contained in the scorpion venom. All of the previously reported cases had normal coronary angiogram. We report a case of a 65-year-old woman who presented with severe scorpion sting and was treated with prazosin. But a few hours later, she developed acute anterior wall MI. Coronary angiogram revealed the presence of significant stenosis in coronary arteries. As acute MI owing to significant coronary artery disease can be evident after severe scorpion envenomation, so every case of acute coronary syndrome following scorpion sting needs early diagnosis, thorough cardiovascular evaluation and appropriate treatment.
