    Abstract Cardiac sonographers often perceive premature beats as a limiting factor during echocardiography because they alter filling and contractility, and loops recorded during or after a premature contraction are often discarded. Here we present 2 cases in which the incidental occurrence of premature beats on Doppler echocardiography contributed to the diagnosis. (

    Abstract Background: Percutaneous transvenous mitral commissurotomy (PTMC) is the first-line therapy of clinically significant rheumatic mitral stenosis. While the procedure is generally safe, new onset or aggravation of mitral regurgitation (MR) may occur, mainly due to commissural splitting and, less frequently, to leaflet tear and chordal rupture. Papillary muscle rupture (PMR) is exceedingly rare in this setting.
    Case summary: A 74-year-old woman with a history of aortic valve replacement and prior rheumatic mitral commissurotomy presented for worsening exercise intolerance and exertional dyspnoea. Transthoracic echocardiography showed a mean pressure gradient of 10 mmHg and a mitral valve area of 1.0 cm², consistent with clinically significant mitral stenosis. Subsequent PTMC was complicated by anterolateral PMR. However, the resulting MR was unexpectedly only of mild-to-moderate severity. Because of residual mitral stenosis and persisting symptoms, surgical mechanical mitral valve replacement and tricuspid annuloplasty were performed 6 weeks after PTMC. Papillary muscle rupture was confirmed during surgery.
    Discussion: We herein describe the occurrence of PMR induced by PTMC; the resulting MR was unexpectedly of mild-to-moderate severity, as a result of extensive rheumatic lesions limiting valve mobility. This case challenges the dogma according to which PMR invariably leads to severe MR. This might not be necessarily the case when it occurs following PTMC.

    Abstract Background: Stent thrombosis is a potentially lethal complication of coronary angioplasty and responsible for 20% of all post-angioplasty myocardial infarctions. Unusual causes may be overlooked and difficult to identify.
    Case summary: A 70-year-old male with history of triple aortocoronary bypass presented with acute inferolateral ST-segment elevation myocardial infarction (STEMI). Critical stenosis of the vein graft to the right coronary artery was revealed, and with the use of distal embolic protection device, successful angioplasty with stent was performed under double antiplatelet treatment with aspirin and ticagrelor. Two weeks later, he presented again at the emergency department with an acute inferolateral STEMI. Subacute stent thrombosis with complete occlusion of the stented vein graft was evident. Repeated balloon dilatations restored the flow stabilizing the patient; optical coherence tomography showed good stent expansion and apposition. Scrutinizing the patient's history, we discovered comedication with carbamazepine that is a CYP3A4 inducer and reduces ticagrelor's effect. Switching to prasugrel ensured potent antiplatelet treatment, and the patient was discharged 5 days later. The 6-month follow-up was uneventful and free of symptoms.
    Discussion: Stent thrombosis has dire consequences, and the precipitating factors should always be investigated. Inadequate platelet inhibition secondary to non-compliance to therapy or resistance and suboptimal stent expansion/apposition are its main causes. Drug interactions are an underrecognized factor that may significantly alter the potency of antiplatelet drugs and also lead to stent thrombosis; thus, treatment is essential to be tailored to each patient comedication.
