Diagnosis and treatment of effusive-constrictive pericarditis: a case report.

BACKGROUND: Effusive-constrictive pericarditis (ECP) is a rare syndrome involving pericardial effusion and concomitant constrictive pericarditis. The hallmark is a persistently elevated right atrial pressure of >10 mmHg or reduction of less than 50% from baseline despite pericardiocentesis. Aetiologies include radiation, infection, malignancy, and autoimmune disease. CASE SUMMARY: A 71-year-old man with a history of atrial fibrillation, obesity, hypertension, obstructive sleep apnoea, managed with continuous positive airway pressure presented with acute pericarditis complicated by pericardial effusion leading to cardiac tamponade. He was diagnosed with ECP after pericardiocentesis and was managed surgically with a pericardial window. DISCUSSION: Early detected cases of ECP can be managed by medical therapy. Therapeutic interventions include pericardiocentesis, balloon pericardiostomy, and pericardiectomy. This report describes a case of new-onset congestive heart failure secondary to ECP.

Primary neuroendocrine tumour of the right ventricle presenting with heart failure and cyanosis.

A 68-year-old woman presented to the emergency department owing to exertional dyspnoea and bilateral leg oedema for 3 weeks. Her vital signs included the following: heart rate of 95 bpm, respiratory rate of 24 breaths/min, oxygen saturation of 73% on room air and a blood pressure of 184/108 mm Hg. Physical examination revealed tachypnoea with clear lungs to auscultation, elevated jugular veins, cyanosis and bilateral pitting oedema. A chest X-ray demonstrated cardiomegaly without obvious pulmonary oedema. A CT of the chest was negative for pulmonary embolus; however, the scan did reveal a large right ventricular (RV) mass. An echocardiogram with bubble study confirmed a patent foramen ovale with significant right-to-left shunting and a large RV mass that significantly obstructed the pulmonary outflow tract. A cardiac biopsy revealed a low-grade neuroendocrine tumour. The patient underwent successful debridement and adjuvant chemotherapy. She improved greatly and was asymptomatic at a 9-month follow-up visit.

Cardiac surgery in Jehovah's Witness patients: ten-year experience.

BACKGROUND: Cardiac surgery in Jehovah's Witnesses poses unique challenges. We have developed a comprehensive multimodality program for these patients and have obtained excellent results. METHODS: Ninety-one Jehovah's Witness patients underwent cardiac surgery between 2000 and 2010. Preoperative, intraoperative, and postoperative considerations in the conduct of bloodless surgery in the Jehovah's Witness population are discussed. Mortality for isolated coronary artery bypass graft surgery and isolated aortic valve replacement was compared with predicted mortality from The Society of Thoracic Surgeons (STS) risk models. Perioperative outcomes were stratified by urgent and elective status of operations. RESULTS: Mean age was 65±12.4 years. Comorbid conditions included hypertension (84.6%), diabetes mellitus (48.4%), previous myocardial infarction (23.1%), chronic lung disease (38.5%), peripheral vascular disease (20.9%), and renal failure (11%). In-hospital mortality was 5.5% (n=5). Mortality for isolated coronary artery bypass graft surgery and isolated aortic valve replacement was 2.2% (observed to expected ratio=1.05, 95% confidence interval: 0 to 3.02) and 5.6% (observed to expected=1.46, 95% confidence interval: 0 to 3.76), respectively. Other complications included reoperation (all=8.8%, cardiac=2.2%), sepsis (2.2%), sternal wound infection (1.1%), transient ischemic attack (1.1%), renal failure requiring dialysis (1.1%), and prolonged ventilation (18.7%). Major complication rates were not significantly different between the elective group and the urgent group. CONCLUSIONS: Bloodless cardiac surgery in Jehovah's Witness patients can be performed with excellent outcomes in both elective and urgent situations. Mortality rates for isolated coronary artery bypass graft surgery and isolated aortic valve replacement are within the expected 95% confidence intervals of STS predicted mortality.

Electroconvulsive therapy for treatment of major depression in a 100-year-old patient with severe aortic stenosis: a 5-year follow-up report.

Although there is no specific age cutoff for electroconvulsive therapy (ECT) and no absolute contraindication to its use, very old age and the presence of cardiac conditions such as aortic stenosis are factors that may negatively affect the physician's decision to administer ECT in individual cases. We report our follow-up of a 100-year-old woman with severe aortic stenosis who has received ECT safely for 5 years now. No cardiac complications have emerged during this period. Her prior unipolar depressive episode with catatonic features remains in remission with a single prophylactic ECT session every 3 months. We have observed from our experience with this unique case that periodic multidisciplinary re-evaluation of the evolving risk-benefit profile of ECT is essential along with the inclusion of family members in this dialogue. Our patient's course illustrates that neither advanced age nor severe aortic stenosis is an absolute contraindication to ECT even over an extended period of time. Each case needs to be evaluated on its merits. To our knowledge, this case represents the oldest patient in the literature where ECT has been administered safely for such an extended period in the setting of severe aortic stenosis.

Reoperative cardiac surgery in Jehovah's witness patients with patent internal thoracic artery grafts: how far can we push the envelope?

Reoperative cardiac surgery in Jehovah's Witness (JW) patients with patent internal mammary arteries is a formidable surgical challenge. We have successfully performed 2 such cases using creative approaches. The first patient, a morbidly obese woman, presented with an acute coronary syndrome 4 years after off-pump coronary artery bypass grafting (CABG) with a hemoglobin of 10 gm/dL. She was stabilized with stenting of the culprit vessel; erythropoietin therapy was performed to increase her hemoglobin, and surgery was performed electively. The internal thoracic artery (ITA) was dissected and clamped, and intermittent cardioplegia was used for myocardial protection. The second patient needed aortic valve replacement 3 years after a previous CABG using an ITA. Limited dissection was used at redo operation without exposing the ITA. Aortic valve replacement was performed under cold fibrillatory arrest with an open ITA. Successful reoperative cardiac surgery in JW patients requires preoperative preparation using a multidisciplinary team approach and flexible operative planning.

Relationship between coronary angioplasty laboratory volume and outcomes after hospital discharge.

BACKGROUND: Although an inverse association has been established between short-term complications of percutaneous coronary interventions (PCIs) and the volume of angioplasty procedures performed by catheterization laboratories, no data are available on the association between laboratory volume and long-term outcomes. METHODS: A cohort study of 25,222 patients undergoing PCI in 43 laboratories in Pennsylvania from October 1994 to December 1995 was performed by use of the Pennsylvania Health Care Cost Containment Council database. The association of laboratory volume with inhospital, 1-month, and 6-month events was estimated by use of multivariable analyses adjusting for patient and procedural characteristics. RESULTS: Although a higher volume of procedures was associated with reduced inhospital coronary bypass ([CABG] 0.6 odds ratio [OR] for > or =400 vs <400 PCIs/year; 95% CI 0.4, 0.8), it was not associated with CABG occurring within 1 month after discharge (P =.71; OR 1.0, 95% CI 0.6, 1.7). Laboratory volume was also not significantly associated with postdischarge revascularization (PCI or CABG) at 1 month (P =.58; OR 1.1, 95% CI 0.8, 1.4) or 6 months (P =.47; OR 1.04, 95% CI 0.91, 1.19). In addition, laboratory volume was not associated with rates of myocardial infarction (P =.14), death (P =.28), or the combined outcome of PCI, CABG, myocardial infarction, or death (P =.90) at 1 month after hospital discharge. CONCLUSIONS: Although our study confirmed the volume/complication relationship for inhospital CABG, it did not reveal an association between volume and postdischarge events. These results suggest that inhospital complications will remain the standard for assessing laboratory volume and that selective use of higher-volume laboratories may not improve long-term outcomes.
