Optimizing P2 Neochordal Length and Stability in Mitral Valve Repair With Use of a Polypropylene Loop.
Abstract Determining the optimal length of artificial chordae tendineae and then effectively securing them is a major challenge in mitral valve repair. Our technique for measuring and stabilizing neochordae involves tying a polypropylene suture loop onto the annuloplasty ring. We used this method in 4 patients who had moderate-to-severe mitral regurgitation from degenerative posterior leaflet (P2) prolapse and flail chordae. Results of intraoperative saline tests and postoperative transesophageal echocardiography revealed only mild insufficiency. One month postoperatively, echocardiograms showed trivial regurgitat...

Surgical Endoepicardial Linear Ablation for Ventricular Tachycardia With Postinfarction Left Ventricular Aneurysm.
Abstract This retrospective study evaluated the feasibility of surgical endoepicardial linear ablation for ventricular tachycardia in patients with postinfarction left ventricular aneurysm. Sixty-four patients with multivessel coronary artery disease and left ventricular aneurysm but no mural thrombosis of the aneurysm or valve disease were treated at our institution from March 2012 through July 2015. All underwent off-pump coronary artery bypass grafting and left ventricular aneurysm repair by linear plication. Twenty-three patients (35.9%) had ventricular tachycardia and underwent surgical endoepicardial linear ...

Left Ventricular Noncompaction Detected by Cardiac Magnetic Resonance Screening: A Reexamination of Diagnostic Criteria.
Abstract In a previous cross-sectional screening study of 5,169 middle and high school students (mean age, 13.1 ± 1.78 yr) in which we estimated the prevalence of high-risk cardiovascular conditions associated with sudden cardiac death, we incidentally detected by cardiac magnetic resonance (CMR) 959 cases (18.6%) of left ventricular noncompaction (LVNC) that met the Petersen diagnostic criterion (noncompaction:compaction ratio>2.3). Short-axis CMR images were available for 511 of these cases (the Short-Axis Study Set). To determine how many of those cases were truly abnormal, we analyzed the short-axis ...

Cardiac Involvement by Burkitt Lymphoma in a 49-Year-Old Man.
We report a rare case of cardiac involvement by Burkitt lymphoma in a 49-year-old man who presented with a 2-month history of dyspnea and palpitations. A transthoracic echocardiogram revealed 2 intracardiac masses in the right atrium (one of which partially encased the tricuspid valve), myocardial infiltration, and pericardial disease. Results of pleural fluid cytology and flow cytometry confirmed involvement by Burkitt lymphoma. Subsequent chemotherapy markedly reduced the intracardiac tumor burden and resolved the patient's presenting symptoms. Our case highlights the importance of cardiac imaging in diagnosing systemic ...

High-Grade Atrioventricular Block Associated With Acute Influenza.
We report 2 cases of high-grade atrioventricular block associated with acute influenza infection. Both patients-a 50-year-old woman with no history of cardiac disease or conduction abnormalities and a 20-year-old man with a history of complex congenital heart disease and conduction abnormalities-received a permanent pacemaker. In the first case, pacemaker interrogation at 4 months revealed persistent atrioventricular block. In the second case, pacemaker interrogation at 3 months suggested resolution. Whether such influenza-associated changes are transient or permanent remains unknown. We recommend keeping a careful watch o...

Use of Large Balloon Catheter to Treat Infants With Pulmonary Valve Stenosis.
Abstract Balloon pulmonary valvuloplasty is a safe and effective treatment for isolated pulmonary valve stenosis. Several balloon catheters are available for this procedure in neonates and infants. However, obtaining additional vascular access for the double-balloon technique in this population is troublesome, and tricuspid valve injury is a concern. We used a TMP PED balloon catheter to perform valvuloplasty in 2 infants with isolated pulmonary valve stenosis. This thin-walled, relatively large 12-mm balloon catheter can be delivered through a small-diameter sheath. In both cases, the transpulmonary pressure grad...

Altered Mental Status and Hyponatremia After 20 Hours of Amiodarone Therapy.
Abstract A 66-year-old woman with no relevant medical history presented at the emergency department with new-onset atrial fibrillation. We initiated intravenous amiodarone therapy. At 20 hours, the patient experienced severe neurologic symptoms, hyponatremia, and syndrome of inappropriate antidiuretic hormone. We discontinued amiodarone, infused saline solution, and restricted the patient's fluid intake. She recovered in 3 days. This case illustrates that amiodarone-induced syndrome of inappropriate antidiuretic hormone with hyponatremia can occur far earlier than expected during acute amiodarone therapy. PMI...

Posttraumatic Subacute Effusive-Constrictive Pericarditis After a Motor Vehicle Accident.
We report a case of effusive-constrictive pericarditis consequent to a motor vehicle accident. A 32-year-old man with gastroesophageal reflux disease presented with severe substernal chest pain of a month's duration and dyspnea on exertion for one week. Echocardiograms revealed a moderate pericardial effusion, and the diagnosis was subacute effusive-constrictive pericarditis. After thorough tests revealed nothing definitive, we learned that the patient had been in a motor vehicle accident weeks before symptom onset, which made blunt trauma the most likely cause of pericardial injury and effusion.

Mechanical Circulatory Support to Treat Pulmonary Embolism: Venoarterial Extracorporeal Membrane Oxygenation and Right Ventricular Assist Devices.
Abstract Mechanical circulatory support may help patients with massive pulmonary embolism who are not candidates for systemic thrombolysis, pulmonary embolectomy, or catheter-directed therapy, or in whom these established interventions have failed. Little published literature covers this topic, which led us to compare outcomes of patients whose massive pulmonary embolism was managed with the use of venoarterial extracorporeal membrane oxygenation (VA-ECMO) or a right ventricular assist device (RVAD). We searched the medical literature from January 1990 through September 2018 for reports of adults hospitalized for ...

Predicting Left Atrial Appendage Thrombus from Left Atrial Volume and Confirmation by Computed Tomography with Delayed Enhancement.
Abstract Assessing thromboembolic risk is crucial for proper management of patients with atrial fibrillation. Left atrial volume is a promising predictor of cardiac thrombosis. To determine whether left atrial volume can predict left atrial appendage thrombus in patients with atrial fibrillation, we conducted a prospective study of 73 patients. Left atrial and ventricular volumes were evaluated by cardiac computed tomography with retrospective electrocardiographic gating and then indexed to body surface area. Left atrial appendage thrombus was confirmed or excluded by cardiac computed tomography with delayed enhan...

Abstract Speckle-tracking echocardiography has enabled clinicians to detect changes in myocardial function with more sensitivity than that afforded by traditional diastolic and systolic functional measurements, including left ventricular ejection fraction. Speckle-tracking echocardiography enables evaluation of myocardial strain in terms of strain (percent change in length of a myocardial segment relative to its length at baseline) and strain rate (strain per unit of time). Both measurements have potential for use in diagnosing and monitoring the cardiovascular side effects of cancer therapy. Regional and global s...
