J Cardiol 2014; 65:293-7. [PMID: 25113950 DOI: 10.1016/j.jjcc.2014.07.007] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/02/2014] [Revised: 06/24/2014] [Accepted: 07/11/2014] [Indexed: 11/28/2022]
Abstract
BACKGROUND Beta-blockers are used to control the heart rate prior to coronary computed tomography (CT) angiography. However, in-hospital administration is time-consuming, and it is hard to decrease the heart rate to <60 beats per minute (bpm) when the initial heart rate is increased. In this study, we examined whether the single administration of long-acting β-blocker at bedtime before angiography is effective for achieving the target heart rate. METHODS AND RESULTS A total of 314 consecutive patients with a resting heart rate >60bpm who underwent coronary CT angiography were retrospectively collected. Either bisoprolol or atenolol was orally administered the night before to 166 patients (beta group), and no additional medication was administered to the other 148 patients (control group). When the heart rate was >60bpm on arrival, a β-blocker or verapamil was orally administered at the discretion of the physician. Although the baseline heart rate was not significantly different between the groups, the β-blocker treatment the night before significantly reduced the heart rate compared to control group upon arrival at the hospital and at the time of angiography. The rate of achievement of a heart rate ≤60bpm on arrival at the hospital was significantly higher in the beta group, and even after the additional treatment. CONCLUSIONS Bedtime administration of a long-acting β-blocker the night before coronary CT angiography is an effective option to achieve the target heart rate at the time of examination.

Abstract
A 79-year-old male, with a history of percutaneous coronary intervention (PCI), was referred to our cardiovascular department for a detailed examination of blackout caused by sinus arrest only during meals. Ultrasound echocardiography showed normal cardiac contraction with no asynergy, irrespective of the remaining stenotic coronary lesion. An electrophysiological study revealed deteriorated atrioventricular nodal conduction at a Wenckebach point of 70 beats per minute. However, sinus node function was normal as demonstrated by a sinus node recovery time of 1369 ms. Coronary angiography showed triple-vessel disease including the remaining stenotic coronary lesion, and a PCI was performed on the right coronary artery. Nevertheless, sinus arrest during meals was unchanged. Swallow syncope was partially improved by dietary modification; however, pacemaker implantation (PMI) was performed eventually, and the patient became asymptomatic after PMI. <Learning objective: Swallow syncope is a rare cause of syncope that belongs to the neurally mediated reflex syncopal syndromes, which can induce a variety of bradyarrhythmias: sinus bradycardia, sinus arrest, sinoatrial block, atrioventricular block, or atrial and ventricular asystole. In this case, we demonstrated that dietary modification or pacemaker implantation improved swallow syncope due to sinus arrest.>.

Abstract
An 80-year-old man, who had dilated cardiomyopathy with right ventricular (RV) dilatation, underwent implantable cardioverter defibrillator (ICD) implantation for advanced atrioventricular block and primary prevention of sudden cardiac death. Tined and screw-in leads were placed on the right atrial appendage and RV apex, respectively. Ventricular pacing inhibition was detected after surgery due to oversensing by diaphragmatic myopotential occurring only during deep inspiration. We performed re-surgery and switched the screw-in lead for a tined lead. The diaphragmatic myopotential decreased, thereby improving oversensing by diaphragmatic myopotential and ventricular pacing inhibition. It might be beneficial to use a tined lead when placing the ventricular lead at the RV apex for implantation of a pacemaker or ICD if oversensing of diaphragmatic myopotential is observed using a screw-in lead. <Learning objective: Oversensing due to diaphragmatic myopotential is rarely observed. However if it occurs, it becomes a critical problem, which causes pacemaker inhibition or inappropriate ICD shock. However, the method of preventing this problem is unknown. In this case, we demonstrated that a tined-lead may be useful for the prevention of oversensing by diaphragmatic myopotential.>.

Abstract
This report presents the case of a 54-year-old female with Takotsubo cardiomyopathy that recurred 12 years after the first episode. The coronary angiography at the first admission revealed ergonovine-induced coronary vasoconstriction in the left coronary artery, and recurrence recurred after the interruption of vasodilator therapy to prevent vasospasm. In addition, the coronary angiography both in the first and second event demonstrated coronary slow flow phenomenon, which improved after the intracoronary administration of nicorandil. These findings indicate that coronary microvascular constriction plays an important role in the pathophysiology of Takotsubo cardiomyopathy.

Abstract
BACKGROUND Electrical isolation of the pulmonary veins (PV) is crucial for atrial fibrillation (AF) ablation. Conduction gaps on the circumferential PV antrum ablation (CPVA) line sometimes remain, which are sometimes difficult to identify. METHODS AND RESULTS CPVA of the ipsilateral superior and inferior PVs was performed during sinus rhythm or coronary sinus pacing using the NavX system in 22 AF patients, in whom 1 round of CPVA failed to disconnect 26 individual PVs (30%) in 18 patients. In these patients, a local activation map within the CPVA line (PV map) was created by a 20-pole circular mapping catheter with the use of the NavX, with 71 ± 37 sampling points per PV antrum. The conduction gap was defined as a site on the CPVA line, from which the activation proceeded toward the entire PV. The mapped PV antra were comprised of the left superior PV in 11, right superior PV in 10, left inferior PV in 3, right inferior PV in 1 and a left common PV in 1 PV(s). The conduction gaps were identified at 1.4 ± 0.7 sites per PV antrum, with an electrogram amplitude of 0.8 ± 0.7 mV. A point ablation at the gap completely isolated 24 out of 26 PV antra (92%) with 1.9 ± 1.3 applications. CONCLUSIONS The PV map was useful for quickly and accurately identifying the conduction gap(s) after 1 round of CPVA.

Abstract
Diffuse alveolar hemorrhage after percutaneous coronary intervention is a rare complication that has been mostly reported in association with glycoprotein IIb/IIIa inhibitors. We herein report a case of a 64-year-old male who developed a diffuse pulmonary hemorrhage after coronary stent implantation for ST-elevation myocardial infarction. Diagnostic bronchoscopy determined the hemorrhage to be a bland pulmonary hemorrhage, and this pattern suggested that combination therapy with aspirin and ticlopidine was therefore the most likely cause. The combination of aspirin and thienopyridine agents is a routine therapeutic protocol for patients after coronary stent implantation. Therefore, physicians should be aware that this dual antiplatelet therapy might sometimes induce fatal complications.

Abstract
BACKGROUND The elevated D-dimer value is one of the clues used to diagnose acute aortic dissection (AAD), but the rapid D-dimer assay is not used at all emergency hospitals. The fibrinogen/fibrin degradation products (FDP) value is also an indicator of enhanced fibrinolysis and may therefore be a useful marker in patients with AAD. In addition, the association between FDP values and partial thrombosis of the false lumen is not elucidated. PATIENTS The present study enrolled 50 patients (66.5±11.2 years of age; median, 66.5 years of age, male subjects comprised 60.0% of the series) with AAD who were admitted to the hospital between July 2005 and December 2007 and 57 patients with acute myocardial infarction (AMI; 70.8±10.4 years of age; median, 71.0 years of age, male subjects comprised 71.9% of the current series) served as a control group. RESULTS The FDP values (µg/mL) in patients with AAD were significantly higher than those of AMI patients (40.2±78.6; median, 14.7 vs. 5.2±9.8; median, 1.7, p<0.001). A receiver operating characteristic curves analysis showed that an elevated FDP level (2.05 µg/mL) was predictive of a diagnosis of AAD with a sensitivity and specificity of 98% and 54%, respectively. The FDP levels of patients (n=14) who had partial thrombosis of the false lumen were significantly higher than in discharged patients without a surgical repair (n=21) who had a patent or complete thrombosis of the false lumen (35.8±43.2; median, 18.8 vs. 14.0±21.3; median, 5.5, p=0.01). CONCLUSION The measurement of FDP may therefore be useful for the initial assessment of patients with suspected AAD and in the prediction of thrombotic status of the false lumen.
