Iatrogenic acute aortic dissection caused by intervention for spontaneous coronary artery dissection: a surgical case report.

Background: Iatrogenic acute aortic dissection (AAD) caused by cardiovascular intervention is rare. Also rare is spontaneous coronary artery dissection (SCAD), a form of acute coronary syndrome, which develops in relatively young women without coronary risk factors. We encountered type A iatrogenic AAD caused by an intervention for SCAD.

New Treatment for Driveline Infection Following Implantation of a Ventricular Assist Device.

In patients with an implantable ventricular assist device (VAD), driveline infection (DLI) is a challenging complication. Once DLI occurs, it may lead to pump contamination and/or septicemia, which means that early treatment is essential. We hereby report our initial experiences of a mechanically-powered portable negative pressure wound therapy system (Smart Negative Pressure: SNaPTM) to treat DLI at an outpatient clinic.

Ruptured Valsalva Sinus Aneurysm with Ventricular Septal Defect and Double-Chambered Right Ventricle without Heart Failure: A Case Report.

Valsalva sinus aneurysm and double-chambered right ventricle are both rare congenital cardiac anomalies. Ventricular septal defect may be present in approximately 50%-60% of patients with Valsalva sinus aneurysm or approximately 70%-80% of patients with double-chambered right ventricle. However, Valsalva sinus aneurysm, double-chambered right ventricle, and ventricular septal defect rarely coexist in the same patient.

Changeover Trial of Febuxostat and Topiroxostat for Hyperuricemia with Cardiovascular Disease: Sub-Analysis for Chronic Kidney Disease (TROFEO CKD Trial).

Background: The TROFEO trial demonstrated that febuxostat causes greater and more rapid reduction of serum uric acid (s-UA) than topiroxostat. We compared these drugs in patients with chronic kidney disease (CKD) by sub-analysis of the TROFEO trial.

Methods: This sub-analysis targeted patients with an estimated glomerular filtration rate (eGFR) ≤60 mL/min/1.

Surgery for a mitral annulus abscess penetrating into the pericardial cavity.

Although a mitral annulus abscess often develops with infective endocarditis, penetration into the pericardial cavity is a very rare and fatal complication. Herein, we report a case of surgery with thorough debridement and appropriate reconstruction for a mitral annulus abscess with penetration into the pericardial cavity.

Is malnutrition associated with postoperative complications after cardiac surgery?

Background And Aim: Malnutrition is the central component of frailty that has an adverse influence on the prognosis of patients undergoing cardiac surgery. The relationship between malnutrition and postoperative complications was evaluated in a retrospective cohort study.

Long-Term Comparison of Ethyl Icosapentate vs. Omega-3-Acid Ethyl in Patients With Cardiovascular Disease and Hypertriglyceridemia (DEFAT Trial).

Background: Numerous studies have demonstrated a reduction in cardiovascular events when the low-density lipoprotein cholesterol (LDL) level is decreased by statin therapy. However, despite good control of LDL, cardiovascular events may increase if the triglyceride (TG) level is high. We conducted a long-term comparison of treatment of hypertriglyceridemia with ethyl icosapentate (EPA) vs.

Successful Surgical Treatment of Giant Coronary Artery Aneurysm and Concomitant Coronary Artery Fistula to the Pulmonary Artery.

Giant coronary artery aneurysm (GCAA) combined with coronary artery fistula to the pulmonary artery (PA) is rare. A 79-year-old man was accidentally discovered with GCAA. He was operated on by use of aneurysmorrhaphy, and closure of the fistulae was performed.

Surgical treatment for double-chambered right ventricle in a septuagenarian.

The majority of patients with double-chambered right ventricle present during childhood; it is rarely treated in adults. We report the case of a 71-year-old woman who presented with mild fatigue for 2 years. Investigation of an ejection systolic murmur revealed a double-chambered right ventricle with a peak gradient of 147 mm Hg across the right ventricular outflow tract.

An Infected Abdominal Aortic Aneurysm Caused by Helicobacter cinaedi.

We present a rare case of an infected abdominal aortic aneurysm due to Helicobacter cinaedi that was detected by blood culture. A 79-year-old man with lumbago and left lower quadrant pain was admitted for the treatment of an infected abdominal aortic aneurysm. H.

Surgical Extirpation of Apical Left Ventricular Thrombus in Takotsubo Cardiomyopathy.

We report a patient with takotsubo cardiomyopathy who underwent surgical resection of apical left ventricular thrombus. A 59-year-old woman was transferred to our hospital in shock with hypothermia and diabetic ketoacidosis. The electrocardiogram showed ST segment elevation, while echocardiography revealed a reduced ejection fraction with apical and midventricular akinesis.

Papillary fibroelastoma of the right ventricular free wall.

Papillary fibroelastoma is a rare benign cardiac tumor that usually arises from the valvular endocardium and its development in the cardiac chambers is extremely rare. A 52-year-old woman complained of palpitations and echocardiography revealed a cardiac tumor. Resection was performed via the right ventricle and main pulmonary artery under cardiopulmonary bypass.

A persistent sciatic artery aneurysm containing a free-floating thrombus: report of a case.

A persistent sciatic artery is a rare vascular anomaly in which the sciatic artery, which involutes in the embryonic stage, persists as the blood supply to the lower limb. This vascular anomaly is often associated with aneurysm formation. A persistent sciatic artery aneurysm is a rare cause of peripheral arterial embolic disease.

Ruptured common femoral artery aneurysm or abdominal aortic aneurysm?

We encountered a patient with a large retroperitoneal hematoma due to rupture of a common femoral artery aneurysm. A 77-year-old man was transferred to our hospital with left groin pain and shock. Computed tomography demonstrated a large retroperitoneal hematoma involving the left iliofemoral segment with extravasation of contrast into the left groin from a ruptured left common femoral artery aneurysm.

Surgical repair of ruptured abdominal aortic aneurysm with non-bleeding aortocaval fistula.

We present a case of an aortocaval fistula (ACF) without bleeding because a clot was covering the fistula. A 60-year-old man was diagnosed as having a ruptured abdominal aortic aneurysm (AAA) and an aortocaval fistula, by enhanced computed tomography (CT). After the aneurysm had been opened, the fistula was detected, but there was no bleeding because it was covered with clot.

Long-term outcomes of patients undergoing extracorporeal membrane oxygenation for refractory postcardiotomy cardiogenic shock.

Purpose: Postcardiotomy cardiogenic shock is still associated with a poor prognosis. We reviewed patients undergoing extracorporeal membrane oxygenation (ECMO) support for postcardiotomy cardiogenic shock and assessed their long-term outcomes.

Methods: The subjects were 47 patients who received ECMO support for cardiogenic shock after open heart surgery.

We present a case of ruptured abdominal aortic aneurysm with left-sided inferior vena cava. An 82-year-old man was admitted to our hospital with a sudden onset of severe abdominal pain and loss of consciousness. Computed tomography revealed rupture of an infrarenal abdominal aortic aneurysm and a left-sided inferior vena cava.

Prognosis of patients undergoing emergency surgery for type A acute aortic dissection without exclusion of the intimal tear.

Objectives: To investigate the prognosis after emergency surgery for acute type A aortic dissection with an unknown entry site and to identify the predictors of postoperative aortic dilatation.

Methods: The subjects were 102 patients undergoing emergency surgery for acute type A dissection from July 2005 to October 2010. They were divided into group I (n = 45) undergoing aortic surgery without tear resection and group II (n = 57) undergoing resection that included the intimal tear.

Stanford type A aortic dissection with intimal intussusception.

A 51-year-old man presented with acute chest pain and loss of consciousness. Computed tomography showed no intimal flap in the ascending aorta and clear dissection involving the aortic root and arch, as well as the descending aorta. At surgery, the intimal tear was found to be circumferential and dissection extended to the proximal aortic arch with intussusception of the intimal layer.

The effect of combined treatment with Impella(®) and landiolol in a swine model of acute myocardial infarction.

Cardiogenic shock is associated with a high mortality rate in patients with acute myocardial infarction (AMI). We developed a new treatment approach named heart rest therapy (HRT) for complete revascularization in the early stage of AMI using an ultra-short-acting β-blocker (landiolol) and an Impella(®) left ventricular assist device and verified the effect of this therapy in a swine model. In 18 male pigs, AMI was induced by left anterior descending coronary artery occlusion at the level of the second diagonal branch for 120 min, followed by 240 min of reperfusion.
