    Abstract Management of heavily calcified lesions during percutaneous coronary intervention (PCI) is often associated with high incidence of complications and long-term adverse outcomes. There is growing evidence of the efficacy of intravascular lithotripsy (IVL) in de novo coronary lesion preparation; however, little experience has been documented within freshly deployed stent underexpansion. We report a 66-year-old male with a marked stent underexpansion despite extensive lesion preparation due to severe underlying calcification. The stent was resistant to balloon postdilatation; therefore, IVL was applied, resulting in excellent stent expansion. IVL could be considered for treating acute stent underexpansion caused by severe underlying calcification.

    Abstract Introduction. Primary aldosteronism (PA) is caused by autonomous hypersecretion of aldosterone from the adrenal cortex, classically from an adenoma, resulting in sodium and water retention, hypokalaemia and raised blood pressure. The sodium and water retention causes suppression of renin release. The possible cardiac sequelae of aldosterone excess are encountered primarily in patients with secondary hyperaldosteronism due to heart failure, where plasma renin, angiotensin and aldosterone levels are all raised. However, there is also evidence that primary aldosterone excess, in the presence of low renin levels, may also be cardiotoxic. Patients. In this report, we describe five patients with PA, who developed atrial fibrillation (AF) in the absence of structural cardiac lesions and in one case despite good control of blood pressure and electrolytes. Conclusion. In patients with hypertension and AF, who have no evidence of coronary disease or any other underlying cause of AF with preserved systolic function, a diagnosis of PA should be considered.
