Background: Cancellation of transesophageal echocardiography (TEE) tests leads to inefficient use of echocardiography laboratory (echo lab) time and wastes resources.

Objectives: To identify the causes of same-day TEE cancellations in hospitalized patients, to formulate a TEE order screening protocol, and to evaluate its efficacy at implementation.

Methods: We performed a prospective analysis of inpatients referred to a single tertiary hospital echo lab for TEE study by inpatient wards. A comprehensive screening protocol emphasizing active participation of all links directly involved in the chain of inpatient TEE referral was developed and implemented. Comparison of pre- and post-implementation of the new screening protocol on two consecutive periods of 6 months on TEE cancellation rates out of total ordered TEEs stratified by cause categories was performed.

Results: In total, 304 inpatient TEE procedures were ordered during the initial observation period; 54(17.8%) were canceled on the same day. The most common cancellation reasons were equally respiratory distress and patient not in fasted state (20.4% of total cancellations and 3.6% of all scheduled TEEs for each cause). Following implementation of the new screening process, total TEEs ordered (192) and cancelled (16) dropped significantly. A decrease in the rate of each cancellation category was observed, with statistical significance achieved for the overall cancellation rate (8.3% vs. 17.8%, P = 0.003), but not for the individual cancellation categories in split analysis.

Conclusions: A concerted effort to implement a comprehensive screening questionnaire significantly reduced same-day cancellations of scheduled TEEs.

Background: The MitraClip procedure is becoming an acceptable alternative for high-risk patients with mitral regurgitation (MR) due to functional (FMR) or degenerative (DMR) disease and suitable mitral anatomy.

Objectives: To evaluate the results of MitraClip at our institute in carefully selected patients.

Methods: We conducted a retrospective analysis of medical records and echocardiography data from January 2012 to December 2017.

Results: A total of 39 MitraClip procedures in 37 patients (aged 75 ± 12 years, 9 women) was performed. Twenty-four patients presented with FMR, 12 with DMR, and 1 with combined pathology. One-day post-procedure MR was moderate to low in 86.1% of patients, with immediate device success in 88.8%. MR at 1 year was moderate to low in 79% at 1 year. Survival at 1 year was 86% and at 2 years 69.4%. Peri-procedural (< 1 week) death and MitraClip failure occurred in one and three patients, respectively. New York Heart Association score improved to class 1 or 2 in 37% of patients at 1 year vs. one patient at baseline. Post-procedural systolic pulmonary pressure was reduced from 53 (range 48–65) to 43 (range 36–52) mmHg at 1 month with a subsequent plateau at follow-up, to 41 (34–57) mmHg at 6 months, and to 47 (38–50) at 12 months.

Conclusions: MitraClip in severe MR resulted in modest improvement in functional status and pulmonary pressure with a small risk of immediate procedural complications. Outcomes are encouraging considering the natural course of MR and the risks of surgical intervention.

Background: ST-elevation myocardial infarction is caused by occlusive coronary thrombosis where antecedent plaque disruption occurs. When treating STEMI[1] the main goal is to achieve prompt reperfusion of the infarction area. Several studies have demonstrated the efficacy of an aspiration device before percutaneous coronary intervention in patients with acute myocardial infarction.

Objectives: To determine the added value of thrombus aspiration prior to primary PCI[2] by comparing AMI[3] patients with totally occluded infarct-related artery treated with routine primary PCI to those treated with extraction device prior to primary PCI.

Methods: The study group comprised 122 consecutive patients with AMI and a totally occluded infarct artery (TIMI flow 0) who underwent primary PCI. The patients were divided into two groups: 68 who underwent primary PCI only (control group) and 54 who underwent primary thrombus extraction with an extraction device before PCI (extraction group). Baseline clinical and lesion characteristics were similar in both groups. Final TIMI grade flow and myocardial blush as well as 1 year mortality, target lesion revascularization, recurrent myocardial infarction, unstable angina and stroke were compared between the two groups.

Results: Primary angiographic results were better for the extraction group versus the control group: final grade 3 TIMI flow was 100% vs. 95.6% (P = 0.03) and final grade 3 myocardial blush grade 50% vs. 41.18% (although P was not significant). Long-term follow-up total MACE[4] showed a non-significant positive trend in the extraction group (12.96% vs. 24.71%, P = 0.26).

Conclusions: The use of extraction devices for intracoronary thrombectomy during primary PCI in patients with totally occluded infarct artery significantly improved epicardial reperfusion in the infarct-related vessel and showed a trend for more favorable long-term outcome.

Isolated ventricular non-compaction is a frequently underdiagnosed rare congenital cardiomyopathy. The importance of diagnosing this cardiomyopathy lies especially in asymptomatic patients, screening relatives of index cases in order to focus on their follow-up and searching for criteria warranting prophylactic anticoagulation, implantable cardioverter defibrillator and anti-remodeling drugs such as angiotensin-converting inhibitors. We present the clinical and imaging characteristics of this entity and discuss some of the therapeutic dilemmas involving these patients.
