ABSTRACT
BACKGROUND: The recently introduced intravascular lithotripsy (IVL) appears promising and relatively safer than conventional approaches when dealing with calcified lesions. Although there are published reports on this novel technology, data from the real world are limited. In this study, we aim to report on the experience of IVL from a real-world population derived from six European centers that undertake high-volume complex coronary interventions. METHODS AND RESULTS: We enrolled all patients treated with IVL between November 2018 and February 2020 at six centers. Procedural success and complications were assessed along with clinical outcomes, which included: cardiac death, target vessel myocardial infarction (TVMI), target lesion revascularisation (TLR), and major adverse cardiac event (MACE) (composite of cardiac death, TVMI, and TLR). Hundred and ninety patients (200 lesions) with a mean age of 72 years were treated using IVL. Diabetes and chronic kidney disease were present in 50% (n = 95) and 16% (n = 30) of cases, respectively. Acute-coronary syndromes accounted for 91 (48%) of the cases. Most were de-novo lesions (77%; n = 154). Upfront use of IVL occurred in 26% of cases, while the rest were bail-out procedures due to inadequate predilatation with conventional balloons. Adjuvant rotational atherectomy was needed in 17% of cases. Procedural success was achieved in 99% of cases with a complication rate of 3%. During the median follow-up of 222 days, there was two cardiac deaths (1%), one case of TVMI (0.5%), 3 TLR (1.5%) taking the MACE rate to 2.6%. CONCLUSION: Use of IVL appears to be safe and effective in dealing with calcified-coronary lesions. A high success rate was observed with low procedural complications and event rates.

OBJECTIVES: The aim of this study is to assess the feasibility, efficacy and safety of the "RotaTripsy" approach in severe calcified coronary artery lesions. BACKGROUND: Coronary lesions with a high calcium content represent a challenging scenario in interventional cardiology, requiring a proper lesion preparation. In this light, very little is known about the possibility to combine the benefits of rotational atherectomy and intravascular lithotripsy. METHODS: We retrospectively enrolled 34 patients from a real-word, multicenter, cohort of patients affected by severe calcified coronary artery lesions, which required the "RotaTripsy" to obtain a proper lesion preparation. In all the cases, rotational atherectomy and then intravascular lithotripsy were performed as a bail-out strategy following sub-optimal non-compliant balloon expansion. In 53% of the cases, the procedure was guided by intracoronary imaging findings. RESULTS: Procedural success was reported in all the cases, without any in-hospital major complication. Few major adverse clinical events were reported at mid-term follow-up. CONCLUSIONS: "RotaTripsy" can represent a valid therapeutic option for undilatable heavily calcified coronary artery lesions. Our findings demonstrate the feasibility, safety and efficacy of this approach.

Single coronary artery (SCA) is a very rare coronary anomaly. The accurate diagnosis of the entity requires multimodality imaging of the coronary anatomy. SCA is often incidentally diagnosed when patients are investigated for symptoms of suspected coronary artery disease with invasive or non-invasive coronary angiography. There are no established diagnostic electrocardiographic or echocardiographic criteria to identify the presence of SCA, which makes the diagnosis a far-reaching fruit. We present a young male patient presenting with a non-ST elevation myocardial infarction. He was found to have SCA on invasive coronary angiography, which was subsequently confirmed by CT coronary angiography.

We describe a rare case of type B thoracic aortic dissection resulting from a forceful sneeze in a 57-year-old man. The presenting clinical features were not typical and consisted of pleuritic chest pain and breathlessness following a forceful sneeze. There was no haemodynamic compromise. The diagnosis was made incidentally when he underwent a CT pulmonary angiography as part of pulmonary embolism work-up.

The authors describe a case of platypnoea orthodeoxia syndrome in an 83-year-old man with a fenestrated atrial septal defect and severe coronary artery disease. The patient had been admitted to hospital six times in the previous year with acute breathlessness, attributed to paroxysmal atrial fibrillation. The patient's symptoms resolved completely following surgical repair of the defect and coronary artery bypass grafting.
