Endoleak after use of the fenestrated frozen elephant trunk technique to treat acute type A aortic dissection.

Several studies have indicated that the fenestrated frozen elephant trunk (FET) technique enhances early outcomes in cases of acute aortic dissection, although long-term outcomes remain unclear. A case involving a 62-year-old male who experienced endoleak from a fenestration site following total arch replacement using the fenestrated FET technique for a DeBakey type I aortic dissection is reported. The patient underwent successful reoperation involving total arch replacement and reinsertion of the FET.

Embolization of left anterior descending artery due to pledget after a redo surgery.

A 53-year-old man underwent aortic root replacement for acute aortic dissection. Following this procedure, the patient developed a pseudoaneurysm at the aortic root, necessitating reoperation. The subsequent surgery was performed routinely, allowing the patient to be weaned from mechanical ventilation on the same day.

Sutureless Repair for Iliac Vein Bleeding Using an Elastomeric Sealant.

Addressing venous bleeding is a frequent complication of vascular and abdominopelvic surgeries. We present a novel sutureless repair technique using Hydrofit (Terumo, Tokyo, Japan), an elastomeric sealant. In a patient experiencing common iliac vein bleeding during abdominal aortic aneurysm surgery, this technique successfully achieved complete hemostasis.

Occurrence of pseudoaneurysm of the coronary button due to aortic remodeling after Bentall operation.

Here, we present a case report detailing a pseudoaneurysm of the coronary button due to aortic remodeling that occurred 2 years after aortic root replacement. The patient was referred to our hospital with a diagnosis of left coronary artery pseudoaneurysm. Intraoperative findings revealed substantially loosened sutures in both the left and right coronary arteries with bleeding.

Mid-term outcomes of hypogastric artery embolization in endovascular aneurysm repair: a case series.

Hypogastric artery embolization is performed during endovascular aneurysm repair (EVAR) involving the common iliac artery. Within this case series, we have observed elevated rates of sac expansion subsequent to this intervention. April 2009 to March 2021, 22 patients underwent EVAR with hypogastric artery embolization.

Insertion Multi-Parachute Suturing and Knotting (IMS-K) Technique for Aortic Surgery.

Successful surgical interventions for aortic surgery, such as hemiarch repair and total arch replacement, pivot on the foundation of optimal anastomosis. We propose an alternative approach to anastomosis. The "insertion multi-parachute suturing and knotting" (IMS-K) technique entails the deployment of two parachute sutures, which can be effectively employed for both proximal and distal anastomoses.

Severe right ventricular infarction due to iatrogenic aortocoronary dissection successfully treated by surgical repair and extracorporeal membrane oxygenation.

Iatrogenic aortocoronary dissection (IACD) is a rare but potentially fatal complication of percutaneous coronary intervention or coronary angiography (CAG). In particular, if the condition of the patient is complicated by cardiogenic shock and right ventricular (RV) dysfunction, the mortality rate is high. Herein, we report the case of an 85-year-old woman with IACD who underwent elective CAG of the right coronary artery complicated with cardiogenic shock due to RV infarction.

The efficacy of right ventricular pacing for symptomatic left mid-ventricular obstruction.

The serial changes in intraventricular pressure gradient in the left ventricle and NYHA functional classification in each case. Both the left intraventricular pressure gradient and symptoms improved after right ventricular pacing. In one case, the left intraventricular pressure gradient disappeared immediately after right ventricular pacing, while in the others it disappeared during the chronic phase, more than a year later.

Ventricular tachycardia arising from His-bundle.

During tachycardia, His-bundle potentials preceded Purkinje potentials. When the radiofrequency application was performed at a site where Purkinje potentials could be recorded slightly more peripherally than His-bundle potentials, tachycardia temporarily stopped, but was quickly followed by tachycardia with left-axis deviated because of the complication of the left anterior fascicular block.

Outcomes of isolated CABG from "OPCAB favor institution" for patients with left ventricular dysfunction.

Objectives: Although off-pump coronary artery bypass (OPCAB) has been reported to have better short-term results than on-pump coronary artery bypass (ONCAB) in terms of bleeding and stroke even in patients with cardiac dysfunction, details are unknown. The purpose of this study was to evaluate the outcomes of CABG (coronary artery bypass graft) in patients with low cardiac function based on our treatment policy.

Methods: Retrospectively, we reviewed patients with low ejection fraction (< 35%), who underwent isolated OPCAB or ONCAB between 2013 and 2020 in our institute.

Aortic valve replacement of a quadricuspid aortic valve with right coronary artery ostium adjacent to one of the commissures.

Background: Quadricuspid aortic valve is a rare congenital heart disease that may be associated with a different anatomical relationship between the coronary artery ostium and the commissure.

Case Presentation: Herein, we report a case of a 59-year-old woman who underwent aortic valve replacement for a quadricuspid aortic valve with severe aortic regurgitation. Intraoperatively, the aortic valve had four cusps of almost equal size and the right coronary artery arose adjacent to the commissure between the right coronary cusp and one of the two non-coronary cusps.

Impact of supra-aortic vessel dissection on the neurological outcome in surgery for acute type A aortic dissection.

We investigated whether supra-aortic vessel (SAV)s dissection is a risk factor for neurological dysfunction (ND) after surgical repair for type A acute aortic dissection (TAAAD). A retrospective review was done in 178 patients with TAAAD undergoing aortic repair between 2015 and 2019, comparing those with SAV dissection to those without it. Preoperatively, 93 patients (54.

Safety of retrograde cerebral perfusion under moderate hypothermia for hemiarch replacement.

Objectives: Aortic surgeries performed under moderate hypothermia require antegrade cerebral perfusion. The influence of retrograde cerebral perfusion under moderate hypothermic circulatory arrest remains unknown. To clarify this effect, this study aimed to compare the early outcomes of retrograde versus antegrade cerebral perfusion under moderate hypothermia for hemiarch replacement.

Atrial fibrillation ablation in a patient complicated by persistent left superior vena cava and absent right superior vena cava.

A comparison between the three-dimensional contact mapping created by the Ensite system and that created by contrast-enhanced computed tomography angiography (CTA). Right atrial appendage was not well delineated on CTA.

Atypical presentation of isolated traumatic ascending aortic dissection with cardiac tamponade.

Blunt traumatic aortic injury is a rare but life-threatening condition, usually following high-energy trauma. We present the case of a 79-year-old man who was transferred to a hospital complaining of nausea after being struck on the chest. Computed tomography led to diagnosis of ascending aortic dissection with cardiac tamponade.

Antidromic atrioventricular reentrant tachycardia in a patient with Wolff-Parkinson-White syndrome and unapparent preexcitation: A case report.

This is a case of antidromic AVRT in a patient with unapparent preexcitation, and we could successfully diagnose and treat with the careful interpretation of wide QRS tachycardia. We should keep in mind that differentiation between intermittent and unapparent preexcitation is difficult, and some patients with unapparent preexcitation have short refractory periods of those accessory pathways, leading to sudden death.

Fragmented QRS as a predictor of cardiac events in patients with cardiac sarcoidosis.

Background: Multiple spikes within the QRS complex, known as fragmented QRS (fQRS), are associated with the occurrences of ventricular arrhythmic events (VAEs) in patients with Brugada syndrome and hypertrophic cardiomyopathy. However, the association between fQRS and occurrence of VAEs in patients with cardiac sarcoidosis (CS) has not been elucidated.

Methods: We evaluated the associations between fQRS and cardiac events including VAEs [non-sustained ventricular tachycardia (NSVT), sustained ventricular tachycardia (VT), and ventricular fibrillation (VF)], hospitalization for heart failure, and all-cause death in 68 patients with CS (30 patients with fQRS vs.

Late-Stage Löffler's Endocarditis Mimicking Cardiac Tumor: A Case Report.

Löffler's endocarditis (cardiac involvement in hypereosinophilic syndrome) is rare yet life-threatening if left untreated. We describe a case of hypereosinophilic syndrome presenting as a cardiac mass with an abnormal electrocardiogram. Diagnostic studies of the cardiac mass strongly suggested a malignant cardiac tumor invading the papillary muscle.

Sutureless hemostasis of a coronary sinus rupture with Hydrofit.

Coronary sinus rupture (CSR) is a rare operative complication, and a standard procedure for its treatment has not been established. We report successful repair of a CSR in a 68-year-old man who underwent total arch replacement for type A acute aortic dissection. CSR was caused by the coronary sinus cannulation for retrograde cardioplegia and was detected during cardiopulmonary bypass weaning.

Fluoroless and contrast-free catheter ablation without a lead apron in routine clinical practice.

The technique of catheter ablation has been improved within the past few decades, especially by three-dimensional (3D) mapping system. 3D mapping system has reduced radiation exposure but ablation procedures still require fluoroscopy. Our previous study showed the safety and efficacy of catheter ablation based on intracardiac echogram combined with CARTOSOUND/CARTO3 system, however fluoroscopy use for an average of 16 min is required for this procedure.

Left ventricular outflow tract obstruction by transatrial left ventricular cannulation.

Transatrial cannulation of the left ventricle was introduced as a safe and easy cannulation method for antegrade arterial return in type A aortic dissection. However, because of the paucity of clinical reports, little is known about the complications or shortcomings of this technique. Herein, we report a case of pulmonary haemorrhage resulting from left ventricular outflow obstruction, necessitating the exchange of the arterial cannulation site.
