Coronary lithotripsy is a novel approach to percutaneous coronary intervention (PCI). It is based on well-established technology dating back to 1980 when lithotripsy was first used to treat renal calculi. Its application in cardiovascular medicine is a more recent development that involves using a low-pressure lithotripsy balloon to deliver unfocused acoustic pulse waves in a circumferential mechanical energy distribution. This causes fracturing of calcification within the surrounding vasculature, facilitating optimal stent deployment.
This article aims to review recent clinical experience and the published data regarding intravascular lithotripsy (IVL). All relevant articles were identified via PubMed using keywords including “intravascular lithotripsy”, “shockwave” and “coronary”. All studies that contained published datasets regarding IVL with patient numbers >50 were included for review. There were 116 results found. After reviewing all the publications, articles were then tabulated and 17 were found to be relevant, including only four clinical studies.
In this review we found that intracoronary lithotripsy for heavily calcified arteries appears to be a safe, effective, easy-to-use method of dealing with an otherwise technically-challenging and high-risk scenario. It appears to carry low risk, uses low pressures, and exerts its effects on both superficial and deep intravascular calcium. Further prospective data with long-term follow-up will be required to explore both the off-label uses of IVL (such as post-stent dilatation), and the long-term patency of these vessels.

We describe a case of primary meningococcal Y effusive pericarditis in a previously fit and well 35-year-old man who presented with a rapidly developing pericardial effusion resulting in cardiac tamponade. This is a rare, but important, cause of primary pericardial disease, and only the fourth documented case of primary meningococcal pericarditis due to Neisseria meningitidis serotype Y. Our patient was successfully treated with a pericardial drain and intravenous ceftriaxone. Our case highlights the importance of adverse clinical features such as temperature >38°C, subacute course, large effusion or tamponade, and non-steroidal anti-inflammatory drug (NSAID)/aspirin failure, which can identify patients who require close observation as they are at higher risk of complications.

Coronary physiology is the collective term for a group of indexes aimed at directly measuring the intracoronary haemodynamic changes that occur across a stenosis in order to guide revascularisation decision-making. Fractional flow reserve (FFR) uses pharmacological dilatation and miniaturised pressure-wires to measure coronary pressure proximal and distal to a stenosis, thereby estimating flow reduction across a stenosis. Several clinical trials have shown that FFR-guided revascularisation improves clinical outcomes, and that deferring revascularisation in patients shown by FFR to have non-haemodynamically significant lesions is safe. Instantaneous wave-free ratio (iFR) is a novel technique that measures the ratio of distal coronary to aortic pressure during a specific period in diastole that obviates the need for pharmacological vasodilatation. Recent randomised-controlled trials have shown iFR to be non-inferior to FFR with respect to major adverse cardiac events, while reducing adverse procedural symptoms and procedure duration.

Thrombus aspiration during primary percutaneous coronary intervention (PCI) has been extensively studied. Conflicting results have consistently emerged, hence, no clear guidance has been produced. The authors have examined several key clinical trials and meta-analyses, and discovered, arguably, major flaws within the designs of most trials, thus, accounting for the persistently discordant results. The authors conclude that there is some evidence to support the selective use of thrombectomy in primary PCI but a large-scale trial with the appropriate patient selection criteria is needed in order to substantiate or refute the argument.
