Left ventricular free wall perforation by a right ventricular pacemaker lead: a case report.

Background: Lead perforation is one of the major complications of pacemaker implantation, but cases of right ventricular (RV) lead perforation through the septum and left ventricle are rarely reported. We described a rare case of left ventricular (LV) free wall perforation by an RV lead and the management of this complication.

Case Summary: An 84-year-old man was admitted with a dual-chamber pacemaker due to pacing failure caused by an RV lead fracture.

Extended thoracic endovascular aortic repair for residual aortic dissection after type A aortic dissection repair.

Objective: We investigated the outcomes of extended coverage of the descending thoracic aorta by thoracic endovascular aortic repair (TEVAR) for residual chronic type B aortic dissection after type A aortic dissection (TAAD) repair.

Methods: From November 2015 to August 2020, 36 patients underwent extended TEVAR for residual intimal tear after TAAD repair. We specifically investigated the methods and outcomes of this procedure.

Successful Treatment of Giant Ascending Aortic Aneurysm with Takayasu Arteritis.

A 50-year-old man who suffered from dyspnea on effort with hearing loss was referred to our hospital. Computed tomography angiography revealed a giant 90-mm diameter ascending aortic aneurysm with severe calcification and neck vessel occlusion. Transthoracic echocardiography revealed moderate-to-severe aortic regurgitation.

Midterm outcome of aortic valve neocuspidization for aortic valve stenosis with small annulus.

Objective: At our institution, we actively perform aortic valve neocuspidization (AVNeo) for aortic valve stenosis (AS) with a small annulus. In this report, we aimed to evaluate the midterm outcome of AVNeo for AS with a small annulus.

Methods: From February 2011 to May 2017, we performed AVNeo for AS with a small annulus in 34 patients.

Aortic valve neocuspidization in patients under 65 years old.

Objective: We aimed to elucidate the surgical outcomes of aortic valve neocuspidization (AVNeo) in patients under 65 years old.

Methods: From December 2010 to February 2019, we performed AVNeo in a total of 168 patients. Of them, we evaluated 36 patients aged under 65 years.

Patterns of aortic remodelling after total arch replacement with frozen elephant trunk for acute aortic dissection.

Objectives: We investigated the outcomes of total arch replacement with frozen elephant trunk (FET) for Stanford type A acute aortic dissection and the patterns of postoperative aortic remodelling from computed tomographic (CT) findings.

Methods: From April 2015 to November 2018, we performed total arch replacement with FET for Stanford type A aortic dissection in 30 patients. Postoperative contrast-enhanced CT showed the position of the FET distal end, the number and the site of communications between the lumina and the presence or absence of aortic remodelling.

Combined Direct Endarterectomy and Fogarty Thrombectomy with Endovascular Therapy for Subacute Occlusion of the Superficial Femoral Artery.

A 78-year-old woman with a prior history of a right femoropopliteal bypass 5 years before and a coronary artery bypass graft 3 months before was admitted for a non-healing ulcer on her right foot. A computed tomography angiogram revealed occlusion of her superficial femoral artery (SFA) from its orifice to the anastomotic site of the bypass graft. The lesion was thought to consist of a partial atherosclerotic plaque with a large number of relatively fresh thrombi, referring to an angiogram of her lower extremity 3 months ago.

Early and mid-term results of isolated aortic valve neocuspidization in patients with aortic stenosis.

Objectives: This study aimed to elucidate the surgical outcome of aortic valve neocuspidization (AVNeo) in patients with aortic stenosis (AS).

Methods: From December 2010 to June 2017, we performed AVNeo for aortic valve pathologies in 144 patients. Of them, we evaluated 57 patients with AS who underwent AVNeo.

Comparison of aortic annulus dimensions after aortic valve neocuspidization with those of normal aortic valve using transthoracic echocardiography.

Objectives: This study aimed to elucidate the physiological feasibility of aortic valve neocuspidization (AVNeo) by comparing the aortic annulus dimensions between patients after AVNeo and patients with normal aortic valves.

Methods: From December 2010 to October 2017, we performed AVNeo for various aortic valve pathologies in 147 patients. Of these patients, the aortic annulus dimensions were measured in 25 patients who underwent AVNeo for aortic valve disease as follow-up examination and compared with those measured in 15 patients who had normal aortic valves.

Optimal Time for Pharmacological Treatment of Abdominal Aortic Aneurysm.

Background: Abdominal aortic aneurysm (AAA), if left untreated, poses the main risks of progressive expansion, rupture, and hemorrhage, leading to death. Large AAA with a risk of rupture is usually treated by graft replacement or endovascular aneurysm repair. Nonsurgical treatment is not an alternative for large AAA, but is potentially beneficial for small AAA which usually requires a watchful waiting approach with medication.

Treatment of prosthetic valve endocarditis by aortic valve neocuspidization using bovine pericardium.

A 78-year-old man who had undergone aortic valve and ascending aorta replacements presented with fever and was referred to our hospital. Blood culture revealed Gram-positive cocci, thus antibiotic therapy was started. Brain magnetic resonance imaging showed fresh cerebral infarction without cerebral haemorrhage or mycotic aneurysm.

Left ventricular perforation and dissecting subepicardial hematoma after catheter ablation for Wolff-Parkinson-White syndrome.

Radiofrequency catheter ablation of accessory bypass tracts has become a widely accepted therapy for Wolff-Parkinson-White (WPW) syndrome. The procedure typically has a high success rate with a low incidence of complications. Left ventricular perforation is a rare but serious complication of catheter ablation.

Barium-enhanced imaging of the coronary vasculature of the porcine myocardium: empirical investigation into the theory of the ventricular myocardial band.

Objective: The ventricular myocardium is thought to exist as a single continuous muscle band that extends from the pulmonary artery to the aorta, wrapped into a double helical coil Torrent-Guasp's theory of the ventricular myocardial band (VMB). The purpose of this study was to examine the coronary blood supply to the VMB and to evaluate the effect of coronary blood systems on structure-function relations in the myocardium.

Methods: VMBs of nine swine hearts were unwrapped after postmortem barium coronary angiography.

A surgical case of lung cancer in a patient with the left superior and inferior pulmonary veins forming a common trunk.

The anatomical abnormalities of the pulmonary veins may have a serious impact on complications that may arise during pulmonary lobectomy. We present a surgical case of left lung cancer in a patient, who was a 69-year-old male, with the left superior and inferior pulmonary veins forming a common trunk outside the pericardium. In this present case, because of extensive adhesions, incomplete lobulation, and tumor infiltration of the main pulmonary artery, we could not identity the common trunk with certainty before excising the left upper lobe.
