Tricuspid valve regurgitation in orthotopic heart transplant recipients is common. Surgical corrections have been the mainstay of the treatment for diuretic‐refractory heart failure due to severe tricuspid regurgitation. However, post‐transplant patients inherently carry higher surgical risk owing to previous sternotomy and immunocompromised state. We report a case of successful percutaneous edge‐to‐edge tricuspid valve repair for severe tricuspid regurgitation after cardiac transplantation. A 27‐year‐old man with a history of idiopathic restrictive cardiomyopathy status after orthotopic heart transplant presented with severe right‐sided heart failure symptoms. A transthoracic echocardiogram showed bi‐atrial enlargement and moderate‐to‐severe tricuspid regurgitation, and an increase to the severe range with exercise. Percutaneous edge‐to‐edge tricuspid valve repair was performed. The patient's symptoms improved, and follow‐up echocardiogram showed mild tricuspid regurgitation. Percutaneous tricuspid valve repair can be considered as an alternative option to conventional surgery for symptomatic severe tricuspid regurgitation in orthotopic heart transplant recipients with suitable anatomy.

Background: Positive T wave in lead aVR has been shown to predict an adverse in-hospital outcome in patients with anterior wall ST-segment elevation myocardial infarction (STEMI). However, the prognostic value of positive T wave in lead aVR on a long-term outcome has not been fully explored.Methods: We performed a retrospective analysis of 190 consecutive patients with first anterior wall STEMI who underwent an emergent coronary angiogram. Patients were divided into those with positive T wave > 0 mV and those with negative T wave ≦ 0 mV in lead aVR. Baseline and angiographic characteristics, and in-hospital revascularization procedures were recorded. In addition, in-hospital and 1-year major adverse cardiac events (MACE) including death, recurrent myocardial infarction, and target vessel revascularization were recorded.Results: Among 190 patients, 37 patients (19%) had positive T wave and 153 patients (81%) had negative T wave in lead aVR. Patients with positive T wave had higher rate of left main disease defined as stenosis ≥50% (11% vs. 2%, p = .028) than those with negative T wave. Patients with positive T wave had higher rate of 1-year MACE (38% vs. 13%, p < .001) driven by higher all-cause mortality (27% vs. 5%, p < .001). Positive T wave was an independent predictor for 1-year MACE (OR 2.74; 95% CI 1.04-7.15; p = .04).Conclusion: Positive T wave in lead aVR was an independent predictor for 1-year MACE in patients with first anterior wall STEMI.

Background: ST-segment elevation in lead aVR predicts left main and/or three-vessel disease (LM/3VD) in patients with acute coronary syndromes. ST-segment elevation in lead aVR is generally reciprocal to and accompanied by ST-segment depression in precordial leads. Previous studies have assessed the independent predictive value of ST-segment elevation in lead aVR for LM/3VD in non-ST-segment elevation acute coronary syndrome and have reported conflicting results.Methods: We performed a retrospective analysis of 379 patients with non-ST-segment elevation myocardial infarction (NSTEMI). Electrocardiograms on presentation were reviewed especially for ST-segment elevation ≥0.05 mV in lead aVR and ST-segment depression ≥0.05 mV in more than two contiguous leads in any other leads.Results: Among 379 patients, 97 (26%) patients had ST-segment elevation in lead aVR and 88 (23%) patients had LM/3VD. Patients with ST-segment elevation in lead aVR had a higher rate of LM/3VD (39% vs. 18%; P < 0.001) and in-hospital revascularization (73% vs. 60%; P = 0.02) driven by a higher rate of in-hospital coronary artery bypass grafting (19% vs. 7%; P < 0.001) than those without ST-segment elevation in lead aVR. On multivariate analysis, ST-segment elevation in lead aVR (odds ratio [OR] 2.05; 95% confidence interval [CI] 1.10-3.77; P = 0.02) and ST-segment depression in leads V1 -V4 (OR 2.99; 95% CI 1.46-6.15; P = 0.003) were independent predictors of LM/3VD.Conclusion: This study demonstrates that ST-segment elevation in lead aVR is an independent predictor of LM/3VD in patients with NSTEMI.
