Pulmonary artery accelerated flow revealing Hodgkin's lymphoma

We present a case in which transthoracic echocardiography was the first diagnostic tool to suspect mediastinal Hodgkin's lymphoma by revealing a change in the hemodynamic of left pulmonary artery flow, and it was used as a follow-up method for monitoring treatment efficacy by demonstrating a normalization of pulmonary artery hemodynamics

Accordion phenomenon in the radial artery should we treat the radial as a coronary artery?

The accordion phenomenon is a well-known finding mechanism in the field of interventional cardiology. It is a benign condition and has mainly been described in tortuous coronary arteries during percutaneous coronary interventions. It is believed to be induced by a stiff guidewire. However, this phenomenon has not been observed previously in the radial artery. We present a case of accordion phenomenon in the radial artery, which was successfully resolved after the catheters and the wire were retrieved, with the pseudolesions found to have completely disappeared in subsequent image findings

Arterio-venous fistulae: a possible complication of transradial approach with a possible non invasive management

Arteriovenous fistulae is rarely reported as a complication of percutaneous coronary interventions with trans-radial approach

We report herein a case of radial arteriovenous fistulae that was treated conservatively by applying manual compression and avoiding surgical intervention

[Regression spontanee de la coarctation de l'aorte chez le nourrisson]

Coarctation of the aorta in neonates and small infants is, in most cases, a severe congenital malformation and requires a rapid surgical treatment or interventional catheterization. To our knowledge, and so far, no cases of coarctation of the aorta have spontaneously improved. We report three cases of coarctation diagnosed in young infants and considered as moderate forms on physical exam and/or ultrasound study which evolved to partial or complete regression without any treatment

Impact of valvular prosthesis type on cardiovascular outcomes in patients on chronic dialysis

There is conflicting evidence guiding valve prosthesis selection in patients with end-stage renal disease on dialysis. We sought to determine, after reviewing the relevant literature, the best valve substitute in patients on chronic dialysis. A total of 9 retrospective studies compared the outcomes of two valves, showing similar results and highlighting the safety of implanting bioprostheses in patients on chronic dialysis. Standards of valve selection have changed over time; it has long been believed that tissue valves undergo premature degeneration due to calcium metabolism derangements in patients with end-stage renal disease. Bleeding was the most common valve-related complication and represented a major drawback of mechanical valves. Two studies demonstrated a survival advantage in favour of mechanical prostheses. It can be concluded that surgeons should not hesitate to implant bioprostheses because singular valve decomposition would be uncommon in this patient population. Prosthesis selection should be based on the same criteria as those used for non-dialysis patients

Tako-Tsubo Cardiomyopathy Triggered by Misdirection

Tako-Tsubo cardiomyopathy (TTC), also known as transient left ventricular apical ballooning syndrome or stress-induced cardiomyopathy, is a novel reversible cardiomyopathy mimicking acute myocardial infarction without epicardial coronary artery disease. The exact physiopathology of TTC remains unclear. It is usually precipitated by acute physical or emotional stress and it most commonly affects postmenopausal women. The growing number of clinical cases of TTC have demonstrated a wide field of possible etiologies beyond the emotional stress. We report a case of a 67-year-old postmenopausal woman who was being supplemented by enteral feeding via a nasogastric tube and who developed TTC due to misdirection, probably favored by the mechanical blockade by the nasogastric tube, while swallowing the drug pills.

[Cardiac tumor epidemiology in adults in Lebanpn]

Primary cardiac tumors are rare but potentially fatal. No studies have discussed this issue yet on the national level. We describe the epidemiology of cardiac tumors in adults in Lebanon. The data were taken from the hospitals, the patients and/or their doctors by means of a questionnaire. Fifty-seven cases of cardiac tumors were found, mainly myxomas in the left atrium. Dyspnea was the most frequent symptom. Transthoracic echocardiography was the main diagnostic tool. Transesophageal echocardiography was inconstantly made, scanner and MRI rarely while contrast echocardiography has never been used. Almost half of the patients had a follow-up and none had a familial screening. The collected data urged us to propose a unique and homogenous strategy for diagnosis, treatment and follow-up of cardiac tumors in Lebanon
