A 74-year-old woman presented with progressive dyspnea on exertion. Transthoracic echocardiography (TTE) demonstrated significant left ventricular outflow tract (LVOT) obstruction with a pressure gradient of 100 mmHg caused by a sigmoid septum (SS). Mitral regurgitation (MR) of a mild to moderate degree occurred due to systolic anterior motion (SAM) of the anterior mitral leaflet (AML), with no intrinsic mitral valve (MV) abnormality. Myectomy of the hypertrophied septal bulge ameliorated the pressure gradient to 8 mmHg with similar MR. However, just before the sternal closure, hemodynamic status deteriorated drastically to ventricular fibrillation. MR exacerbated to a severe degree with an uncertain etiology; thus, a mechanical prosthetic valve was implanted. The postoperative course was complicated by prolonged mechanical ventilation due to massive pulmonary edema and complete atrioventricular block (CAVB) requiring permanent pacemaker implantation. One year postoperatively, the patient is asymptomatic and TTE revealed no residual pressure gradient with an iatrogenic ventricular septal defect (VSD). This case, the first published surgical experience of SS, may indicate that secondary MR, which is usually relieved by sufficient myectomy in hypertrophic cardiomyopathy (HCM), can exacerbate markedly, and that myectomy might not be advisable in SS. The therapeutic strategy must be considered carefully before embarking on surgical intervention.

We report a case of a patent venous graft for the left anterior descending branch 25 years after surgery. In 1986 at the age of 59 years, the patient underwent coronary artery bypass grafting( CABG) to the left anterior descending(LAD)artery using a saphenous vein graft (SVG). In 2011, twenty-five years after the surgery, the patient experienced a chest pain and was hospitalized. Due to a strong chest pain and pulmonary edema, emergency coronary angiography was performed under tracheal intubation. The SVG was patent, but severe stenosis was found proximal to the middle of the graft. Although percutaneous coronary intervention with a bare-metal stent was performed, the patient died of ventricular fibrillation on the 38th postoperative day. The use of arterial grafts for CABG is currently predominant, but SVG should still be considered a reliable alternative.

A retrospective study was conducted at Tongji Forensic Medical Center in Hubei (TFMCH) from 1999 to 2014. Forty-nine cases of sudden unexplained nocturnal death syndrome (SUNDS) were collected. The SUNDS rate was 1.0% in the total number of cases, in which an incidence was fluctuating over the years. Interestingly, April and January, and 3:00 to 6:00 AM were the peak months and times of death. Among the decedents, farmers and migrant workers accounted for 67.3%. The syndrome predominantly attacked males in their 30s. One victim had sinus tachycardia. Thirteen victims (26.5%) were witnessed and had abnormal symptoms near death. Macroscopically, compared to sudden noncardiac deaths, the weights of brain, heart, and lungs had no statistical difference in SUNDS. Microscopically, the incidence of lung edema (45 cases, 91.8%) was significantly higher in SUNDS group than in the control group (27 cases, 55.1%). 82.9% of 35 SUNDS cases examined displayed minor histological anomalies of the cardiac conduction system (CCS), including mild or moderate fatty, fibrous or fibrofatty tissue replacement, insignificant stenosis of node artery, and punctate hemorrhage in the node area. These findings suggested that minor CCS abnormalities might be the substrates for some SUNDS deaths. Therefore, SUNDS victims might suffer ventricular fibrillation and acute cardiopulmonary failure before death. Further in-depth studies are needed to unveil the underlying mechanisms of SUNDS.

Patients with end-stage renal disease (ESRD) show characteristic abnormalities in cardiac structure and function. We evaluated the influence of these abnormalities on adverse cardiopulmonary outcomes after living donor kidney transplantation in patients with valid preoperative transthoracic echocardiographic evaluation. We then observed any development of major postoperative cardiovascular complications and pulmonary edema until hospital discharge. In-hospital major cardiovascular complications were defined as acute myocardial infarction, ventricular fibrillation/tachycardia, cardiogenic shock, newly-onset atrial fibrillation, clinical pulmonary edema requiring endotracheal intubation or dialysis. Among the 242 ESRD study patients, 9 patients (4%) developed major cardiovascular complications, and 39 patients (16%) developed pulmonary edema. Diabetes, ischemia-reperfusion time, left ventricular end-diastolic diameter (LVEDd), left ventricular mass index (LVMI), right ventricular systolic pressure (RVSP), left atrium volume index (LAVI), and high E/E' ratios were risk factors of major cardiovascular complications, while age, LVEDd, LVMI, LAVI, and high E/E' ratios were risk factors of pulmonary edema. The optimal E/E' cut-off value for predicting major cardiovascular complications was 13.0, showing 77.8% sensitivity and 78.5% specificity. Thus, the patient's E/E' ratio is useful for predicting in-hospital major cardiovascular complications after kidney transplantation. We recommend that goal-directed therapy employing E/E' ratio be enacted in kidney recipients with baseline diastolic dysfunction to avert postoperative morbidity.

Boris Wan, a mythical figure of the post war years, just missed the succession of therapeutic advances in cardiology in the mid of the XXth century. A acute articular rhumatism occurred in 1932, as penicillin, discovered in 1928, was not yet on the market. Aortic regurgitation followed. On July 20, 1955, a pulmonary edema occurs as the first case of open-heart surgery with extra corporeal circulation is performed by Charles Dubost in 1955. But only the aortic stenosis may benefit from this surgery. Regarding aortic regurgitation, an artificial valve is necessary. The first Starr-Edwards heart valve is implanted on August 25, 1960. June 23 , 1959, Boris Wan made a sudden loss of consciousness probably due to a ventricular fibrillation. It is this same year that the electric shock is used for the first time, but only in hospital. Boris Wan died during transport to the Laennec hospital. Ambulances were not yet equipped with defibrillator.

Spontaneous and simultaneous multivessel coronary artery spasm may present with multisite myocardial ischemia, atrioventricular block, acute lung edema, cardiogenic shock, or ventricular fibrillation. In a case of syncope caused by vasospasm, the underlying mechanism may be complex, such as atrioventricular block and/or ventricular arrhythmia. Dual implantable cardioverter defibrillator (ICD) placement should be considered along with optimal medical treatment. This report is a description of a 57-year-old male patient who was admitted to the hospital with chest pain followed by loss of consciousness. As the patient had bradycardia, a diffuse spasm, and life-threatening ventricular arrhythmia during ischemic episodes, a dual ICD device was implanted. ICD treatment may be a good option in cases with a diffuse spasm that is hard to control with medical treatment due to the risk of life-threatening ventricular arrhythmia.

Tako-tsubo cardiomyopathy (TTC) is a transient myocardial dysfunction mainly affecting the left ventricle, mimicking an acute coronary syndrome. This condition can be precipitated either by psychological/physical stressful events or by a number of medical conditions among which are seizures and status epilepticus (SE). The evolution is mostly favourable but sometimes TTC can evolve into life-threatening conditions. We searched for cases of TTC among all consecutive SE episodes observed at our department during the period 2013-2018. In addition, we searched MEDLINE (accessed through PubMed from inception to August 31, 2018) to identify reports of patients with TTC associated with an SE episode. Three TTC cases among 392 SE episodes were identified. Adding our cases to those previously reported, overall, we identified 45 cases of TTC induced by SE. The majority were females of around 60 years of age experiencing a first episode of SE with prominent motor phenomena, mostly in the context of remote aetiology. The most frequent presenting symptom was mild hypotension but cases with a severe presentation were also reported. The overall evolution was positive in all cases but some severe complications such as pulmonary oedema, cardiogenic shock, ventricular fibrillation, and a giant apical thrombus were also reported (19%). TTC may be a rare potentially life-threatening consequence of SE. It is frequently unrecognized, and therefore underdiagnosed. Clinicians dealing with SE should be aware of this entity.
