Impact of cone-beam computed tomography for the identification and management of an oral portal of entry in patients with infective endocarditis. A Delphi study.

BACKGROUND: Infective endocarditis (IE) is a rare and life-threatening disease. Cutaneous portal of entry (POE) is predominant for IE, but an oral POE is the second most frequent source. Thus looking for and treating an oral POE in IE patients is of critical importance in order to reduce the risk of IE relapse or recurrence. The objectives of this study were: 1) To reach a consensus on decision-making following the detection of an oral POE on cone-beam computed tomography (CBCT) while they were not identified using the current recommended approach in IE patients (oral examination and orthopantomogram: OPT). 2) To determine whether this consensus differs when regarding the microbiology of IE. MATERIAL AND METHODS: Twenty oral or maxillofacial surgeons participated to this Delphi study. The questionnaire was based on five radiological cases (OPT and matching CBCT) with two scenarios according to the objectives of detecting oral POE in an IE patient (curative in case of oral causative microorganism, and preventive if not) and different therapeutic approaches (surgical or conservative treatment, no treatment) for each of them. Consensus was defined as an agreement rate of ≥75%. RESULTS: The response rate was≥85%. After four rounds, consensus was achieved for all proposals. CBCT changed the decision-making of experts in four cases. In one case, the decision was influenced by the IE microbiology toward a more radical approach in case of oral causative microorganism. CONCLUSIONS: In IE patients, CBCT changed markedly the decision-making of experts by eradicating more oral POE than when using OPT. This could reduce the risk of IE relapse and recurrence.

Mitral regurgitation. Timing of surgery or interventional treatment.

The treatment of mitral regurgitation has changed in recent years because of improvements in the surgical treatment, in particular valve repair, and the advent of interventional techniques, mainly percutaneous edge-to-edge repair. Regardless of the technique used, better results are obtained for interventions in primary mitral regurgitation than in secondary mitral regurgitation, which remains a challenge. Further developments are expected in the future thanks to a better understanding of the epidemiology and the mechanisms of secondary mitral regurgitation, the development of interventional techniques, and a careful evaluation.

Infective endocarditis with symptomatic cerebral complications: contribution of cerebral magnetic resonance imaging.

BACKGROUND: Cerebral complications are well-identified causes of morbidity and mortality in patients with infective endocarditis (IE). Few studies have analysed the impact of brain magnetic resonance imaging (MRI) in IE patients with neurological manifestations. OBJECTIVES: The aims of this study were to assess the MRI contribution to the management of patients with IE neurological manifestations and to compare cerebral CT and MRI findings. MATERIAL AND METHODS: Patients with definite or probable IE and neurological manifestations were prospectively enrolled from 2005 to 2008, in a university hospital (Bichat Claude Bernard Hospital, Paris). Clinical and radiological characteristics and echocardiographic findings were systematically recorded. Brain MRI with angiography was performed and compared to available CT scans. The contribution of MRI results to cerebral involvement staging and to therapeutic plans was evaluated. RESULTS: Thirty patients, 37-89 years old, were included. Nineteen suffered from pre-existing heart disease. Blood cultures were positive in 29 cases and the main micro-organisms were streptococci (n = 14) and staphylococci (n = 13). The IE was mainly located on mitral (n = 15) and aortic valves (n = 13). Neurological events were strokes (n = 12), meningitis (n = 5), seizures (n = 1), impaired consciousness (n = 11) and severe headache (n = 1). MRI findings included ischaemic lesions (n = 25), haemorrhagic lesions (n = 2), subarachnoid haemorrhage (n = 5), brain abscess (n = 6), mycotic aneurysm (n = 7), vascular occlusion (n = 3) and cerebral microbleeds (n = 17). In 19/30 cases, neurological manifestations were observed before the diagnosis of IE. MRI was more sensitive than CT scan in detecting both clinically symptomatic cerebral lesions (100 and 81%, respectively) and additional asymptomatic lesions (50 and 23%, respectively). Therapeutic plans were modified according to MRI results in 27% of patients: antibiotherapy regimen modifications in 7% (switch for molecules with high cerebral diffusion) and surgical plan modifications in 20% (indication of valvular replacement due to the embolic nature of the vegetations revealed by MRI or postponement of surgery due to haemorrhagic lesions). None of the 16/30 (51%) operated-on patients experienced postoperative neurological worsening. In-hospital death occurred in 4 patients. CONCLUSION: In patients with IE neurological manifestations, MRI revealed a broader involvement of the brain (type and number of lesions) than indicated by clinical signs and/or CT scan. With a better disease staging of neurological manifestations, MRI brain imaging may help in patient management and the decision-making process especially for cardiac surgery indication and timing of valve replacement.

Haemophilus parainfluenzae infective endocarditis associated with pelvic abscess: an uncommon complication of endometriosis.

The case of a woman with native mitral valve endocarditis due to Haemophilus parainfluenzae (HPI) associated with a pelvic abscess and endometriosis is reported. Although HPI is an infrequent pathogen involved in endocarditis, association to a gynaecological infection has never been reported. Endometriosis could increase this risk.

Antibiotic prophylaxis of infective endocarditis in patients with predisposing cardiac conditions: French cardiologists' implementation of current guidelines.

BACKGROUND: To prevent infective endocarditis (IE), with the exception of the United Kingdom, antibiotic prophylaxis (AP) is recommended in patients with predisposing cardiac conditions (PCCs) worldwide. To conclude on the relevance of this strategy, how the current guidelines are applied is a crucial point to investigate. The first aim of this study was to assess cardiologists' implementation of the current guidelines. The secondary objective was to identify specific areas where the training and knowledge of French cardiologists could be improved. METHODS: A national online survey was carried out among the 2228 cardiologist members of the French Society of Cardiology. RESULTS: The high risk PCCs for which IE AP is recommended were correctly identified by the vast majority of the respondents so that IE AP is mostly prescribed correctly in such patients. But only 12% identified all the right indications for IE AP according to 13 predefined PCCs (3 at high-risk, 6 at moderate-risk and 4 at low-risk of IE) so that some IE AP misuses are recorded, overprescription in particular. Only 47% prescribed the proper amoxicillin schedule and only 15% prescribed the appropriate clindamycin schedule in cases with penicillin allergy. CONCLUSION: This study evidenced relevant areas where the training of cardiologists could be improved such as knowledge of the risk of IE for certain PCCs and some common invasive dental procedures. Cardiologists' knowledge should be improved before any conclusion can be drawn on the relevance of this AP strategy and its influence on IE incidence.

[Cardiac papillary fibroelastoma and stroke during pregnancy: Case report]. / AVC révélant un fibroélastome pendant la grossesse : case report.

Stroke occurring during pregnancy is linked to high mortality. Stroke may be directly related to pregnancy (e.g. eclampsia, cerebral venous thrombosis), but all the other causes of stroke are possible. Brain magnetic resonance imaging that is not contraindicated during pregnancy remains the reference in this context. We report the case of a woman with severe headache associated with visual disturbances, without hypertension or proteinuria at 32 weeks of pregnancy. MRI revealed multiple recent cerebral vascular accidents. An echocardiogram detected a papillary fibroelastoma of 5mm. Maternal fetal experts determined it safe to continue the pregnancy. Childbirth at 39 weeks was normal uneventful for the newborn and mother. In the postpartum, despite the theoretical operative indication to resect the small residual papillary fibroelastoma, the patient was followed expectantly because of the stable neuro-cardiologic state. A fibroelastoma can be revealed by a stroke during pregnancy. In the postpartum period, an expectant attitude can be reasonably chosen in case of small size of the fibroelastoma.

Position paper of French Interventional Group (GACI) for TAVI in France in 2018.

Aortic stenosis is a frequent disease in the elderly. Its prevalence is 0.4% with a sharp increase after the age of 65, and its outcome is very poor when the patient becomes symptomatic. The interventional procedure known as TAVI (trans-catheter aortic valve implantation), which was developed in France and carried out for the first time in Rouen by Prof. Alain Cribier and his team in 2002, has proven to be a valid alternative to surgical aortic valve replacement. At first, this technique was shown to be efficient in patients with contra-indications to surgical treatment or deemed to be at high surgical risk. Given the very promising outcomes achieved as a result of close heart team collaboration, appropriate patient selection, simplified procedures and reduced complication rates, transfemoral (TF) TAVI is now preferred in symptomatic intermediate risk patients>75 years old according to the latest ESC guidelines. In 2017, in France, TAVI is currently performed in 50 centers with on-site cardiac surgery. The 2016 TAVI outcomes recorded in the French national TAVI registry (France TAVI) are very encouraging and show that for 7133 patients treated (age 83.4±7 years, logistic Euroscore 14%), 87% of whom via the TF approach, cross-over to surgery was very low (0.5%) with a 3.0% in-hospital mortality rate. The substantial increase in TAVI indications and the improvement of its outcomes may in the near future call for a reconsideration of the number of high volume centers authorized to carry out this technique.

Eclipsed mitral regurgitation: an unusual cause of acute heart failure.

AIMS: So far, a total of five patients with eclipsed mitral regurgitation (MR) have been reported in the literature by three different teams. The aim of this article was to detail clinical and echocardiographic characteristics, and outcome of patients presenting eclipsed MR. METHODS AND RESULTS: We defined eclipsed MR as spontaneous appearance, at rest, from 1 min to the next of an acute restriction in the motion of mitral leaflets preventing coaptation and leading to massive MR in patients with normal left ventricular end-diastolic diameter, left ventricular ejection fraction >45%, and baseline MR ≤2. Spontaneous regression occurred within 30 min, and no obvious trigger such as acute hypertension, new-onset arrhythmia, or myocardial ischaemia is present. Clinical data, ECG, echocardiographic data, surgery report, and follow-up status of six patients with eclipsed MR are reported: all were post-menopausal women with median age of 74 [57-80] years presenting hypertension (4/6), chronic kidney disease (5/6), or chronic anaemia (4/6). Five out of six patients experienced acute pulmonary oedema requiring hospitalization and underwent mitral valve replacement because of heart failure recurrence. Two patients died in the first days after surgery while the three others are free of symptoms at, respectively, 56, 18, and 10 months follow-up. CONCLUSION: Eclipsed MR is a clinical and echocardiographic syndrome responsible for heart failure with preserved EF. It is presently underdiagnosed and should be evoked in cases of recurrent acute pulmonary oedema without obvious trigger, in particular in patients presenting discordant evaluation of MR severity over time.

Late results of percutaneous mitral commissurotomy in a series of 1024 patients. Analysis of late clinical deterioration: frequency, anatomic findings, and predictive factors.

BACKGROUND: The optimal use of percutaneous mitral commissurotomy (PMC) in a wide range of patients requires accurate evaluation of late results and identification of their predictors. METHODS AND RESULTS: Late results of PMC were assessed in 1024 patients whose mean age was 49+/-14 years. Echocardiography showed that 141 patients (14%) had pliable valves and mild subvalvular disease, 569 (55%) had extensive subvalvular disease, and 314 (31%) had calcified valves. A single balloon was used in 26 patients, a double balloon in 390, and the Inoue Balloon in 608. Good immediate results were defined as valve area >/=1.5 cm2 without regurgitation >2/4 (Sellers' grade) and were obtained in 912 patients. Median duration of follow-up was 49 months. The 10-year actuarial rate of good functional results (survival with no cardiovascular death and no need for surgery or repeat dilatation and in New York Heart Association [NYHA] class I or II) was 56+/-4% in the entire population. Follow-up echocardiography was available in 90% of the patients who experienced poor functional results after good immediate results and showed restenosis in 97% of these. In multivariate analysis, the predictors of poor functional results were old age (P=0.0008), unfavorable valve anatomy (P=0.003), high NYHA class (P<0.0001), atrial fibrillation (P<0.0001), low valve area after PMC (P=0.001), high gradient after PMC (P<0.0001), and grade 2 mitral regurgitation after PMC (P=0.04). CONCLUSIONS: PMC can be performed with good late results in a variety of patient subsets. Prediction of late events is multifactorial. Knowledge of these predictors can improve patient selection and follow-up.

Functional results 5 years after successful percutaneous mitral commissurotomy in a series of 528 patients and analysis of predictive factors.

OBJECTIVES: This study sought to assess late functional results after successful percutaneous mitral commissurotomy and to determine their predictors. BACKGROUND: Few studies have reported late results of percutaneous mitral commissurotomy or have analyzed their late results regardless of immediate results, despite the fact that late deterioration may well be related either to a decrease in valve area or to poor initial results. METHODS: Between 1986 and 1992, 528 patients underwent successful percutaneous mitral commissurotomy (mean [+/- SD] age 46 +/- 18 years; mean follow-up 32 +/- 18 months). A successful procedure was defined by a mitral valve area > or = 1.5 cm2 and no regurgitation > 2/4. Dilation was performed using a single balloon in 13 patients, a double balloon in 349 and the Inoue balloon in 166. Multivariate analysis was performed with a Cox model. RESULTS: The survival rate for patients in New York Heart Association functional class I or II, with no cardiac-related deaths or need for mitral surgery or repeat dilation, was 76 +/- 6% at 5 years. By multivariate analysis, the independent predictors of good functional results were echocardiographic group (p = 0.01), functional class (p = 0.02) and cardiothoracic index (p = 0.005) before the procedure and valve area after the procedure (p = 0.007). The predictive model derived allowed estimation of the probability of good functional results according to the value of these four predictors for any given patient. CONCLUSIONS: Good functional results were observed 5 years after successful percutaneous mitral commissurotomy in a large series of varied patients. The analysis of predictive factors may provide useful indications for follow-up results in patients undergoing this technique.

Percutaneous mitral commissurotomy for restenosis after surgical commissurotomy: late efficacy and implications for patient selection.

OBJECTIVES: The results of percutaneous mitral commissurotomy were assessed in patients with restenosis after surgical commissurotomy. BACKGROUND: Balloon dilation is feasible in patients with restenosis after surgical commissurotomy, but little is known about its late efficacy. METHODS: We studied 232 patients who had undergone percutaneous mitral commissurotomy a mean of 16 +/- 8 years after surgical commissurotomy. Mean age was 47 +/- 14 years; 81 patients (35%) had valve calcification. All patients had restenosis with bilateral commissural fusion as assessed by echocardiography. Technical failure occurred in 9 patients and the procedure used a single balloon in 7 patients, a double balloon in 95, and the Inoue balloon in 121. RESULTS: Complications were death in 1 patient (0.4%) and mitral regurgitation >2/4 in 10 (4%); 191 patients (82%) had good immediate results (valve area > or =1.5 cm2 without regurgitation >2/4). Predictors of poor immediate results in multivariate analysis were older age (p < 0.001), lower initial valve area (p = 0.01) and the use of the double-balloon technique (p = 0.015). In the 175 patients who underwent follow-up, 8-year survival without operation and in New York Heart Association class I or II was 48 +/- 5%, and 58 +/- 6% after good immediate results. In this latter group, poor late functional results were predicted by higher cardiothoracic index (p < 0.0001), previous open-heart commissurotomy (p = 0.05) and lower final valve area (p < 0.0001) in a multivariate Cox model. CONCLUSIONS: Percutaneous mitral commissurotomy is safe and provides good immediate results in selected patients with restenosis after surgical commissurotomy. After good immediate results, the conditions of more than half of the patients remained improved at 8 years, enabling reoperation to be deferred.

[Recommendations for noncardiac surgery in aortic stenosis]. / Rétrécissement aortique et chirurgie extracardiaque: quelques recommandations.

Aortic stenosis (AS) is the most common valve disease in western countries and its prevalence increases with population aging. AS is an important risk factor for perioperative complications in patients undergoing noncardiac surgery, a common situation in older patients. Preoperative evaluation should be based on a careful cardiac and general examination (risk factors and comorbidities) as well as on the type and urgency of the noncardiac surgery (urgent as opposed to elective). Careful teamwork and communication between the cardiologist, the anesthesiologist and the surgeon is mandatory. It is also critical that the anesthesiologist team is used to managing these high-risk patients. In cases of non-severe AS (>0.6 cm2/m2 of body surface area), the noncardiac surgery can be performed first. If AS is severe (< or =0.6 cm2/m2) and the noncardiac surgery elective, it is appropriate to consider an aortic valve replacement first. In the difficult cases of urgent noncardiac surgery in patients with severe AS, which precludes heart surgery, it is possible either to first proceed with the noncardiac surgery under very careful anesthesiologic management or to perform the percutaneous aortic valve commissurotomy first.

Percutaneous gene therapy using recombinant adenoviruses encoding human herpes simplex virus thymidine kinase, human PAI-1, and human NOS3 in balloon-injured porcine coronary arteries.

Local intracoronary delivery of recombinant adenoviruses expressing anti-migratory or anti-proliferative proteins including human constitutive endothelial nitric oxide synthase (NOS3), plasminogen activator inhibitor 1 (PAI-1), or herpesvirus thymidine kinase (TK) (combined with ganciclovir) was used to prevent neointimal formation in porcine coronary arteries. After balloon injury of the left anterior descending (LAD) coronary artery, animals received an intramural injection of adenovirus (1.5 X 10(9) PFU) carrying either the NOS3 cDNA (AdCMVNOS3, n = 12), the PAI-1 cDNA (AdCMVPAI-1, n = 12), the TK cDNA (AdMLPItk, n = 12), or no cDNA (AdpL+, n = 12). After 28 days, morphometric analysis was performed on coronary sections from all segments demonstrating injury. The internal elastic lamina (IEL) fracture length normalized to the IEL perimeter (initial injury) and the neointimal area normalized to the vessel area (response to injury) were used to generate linear regression lines and calculate an index of stenosis for the respective treatment groups. The response to injury was significantly smaller in AdCMVNOS3- and AdMLPItk-infected animals than in AdpL+-infected animals (slopes = 0.86 +/- 0.05 and 0.69 +/- 0.07 versus 1.11 +/- 0.06, p < 0.005 and p < 0.0001, respectively) but not in AdCMVPAI-1-infected animals (slope = 1.26 +/- 0.04, p = 0.04). No viral shedding was observed and there was no acute systemic toxicity after gene transfer. An increase in neutralizing antibody titers against Ad vectors was observed without any detectable response to the transgene products (NOS3, PAI-1). Local gene transfer of NOS3 and TK may hold promise as a safe and effective adjunctive treatment to reduce neointimal formation after percutaneous coronary intervention in humans.

Value of multiplane transesophageal echocardiography in determining aortic valve area in aortic stenosis.

Aortic valve area determination by transesophageal planimetry and by the continuity equation was compared with hemodynamic measurements in 45 patients with symptomatic aortic stenosis. The correlations between transesophageal echocardiography and hemodynamics were dependent on the amount of valvular calcium, whereas the continuity equation correlated well with hemodynamics in all patients.

Frequency and prognostic value of cardiac troponin I elevation after coronary stenting.

Mild myocardial injuries after coronary angioplasty are associated with adverse late outcomes. The incidence and prognostic value of this phenomenon when using cardiac troponin I (cTnI) after stent implantation is unknown. We studied cTnI and creatine kinase (CK) release in 109 patients after stenting. Clinical success was achieved in 103 patients (94%). In-hospital major adverse coronary events were: death in 1 patient, Q-wave myocardial infarction in 1 patient, and non-Q-wave myocardial infarction in 2 patients. Twenty-nine patients (27%) had postprocedural cTnI increase, 16 (15%) had CK elevation. No preprocedural variables predicted marker elevation. Marker release was related to the occurrence of in-lab complications (59% vs 29% [p = 0.004 for cTnI] and 69% vs 32% [p = 0.011 for CK]). In 34% no explanation was found for cTnI increase. Success was more frequent in patients without cTnI elevation (100% vs 86%, p <0.001). The negative predictive value of cTnI increase was 100% for in-hospital major adverse coronary events (MACE), whereas its positive predictive value was 14%. cTnI and CK concordant elevation was associated with more intra- and postprocedural adverse events. During a mean follow-up of 8+/-3 months, major adverse coronary events were: death in 2 patients, myocardial infarction in 2 patients, and repeat PTCA in 8 patients. cTnI elevation was not predictive of these late MACE. cTnI elevation is common after stenting, and is related to the occurrence of in-lab complications. Its isolated elevation is not a good predictor of MACE. Patients with concordant cTnI and CK elevation seem to be at higher risk of in-hospital MACE.

Influence of percutaneous mitral commissurotomy on left atrial spontaneous contrast of mitral stenosis.

To assess the influence of percutaneous mitral commissurotomy (PMC) on left atrial spontaneous echo contrast of mitral stenosis, transesophageal echocardiography was performed before and 24 to 48 hours after the procedure, and on average, 6 months later in 82 patients. Fifty-nine patients (72%) were in stable sinus rhythm and 23 in permanent atrial fibrillation. Eleven patients (13%) had history of embolism, and 31 were on long-term anticoagulant therapy. The intensity of spontaneous contrast was graded as follows: 0 = no contrast; 1 = slight contrast; and 2 = intense contrast with the typical aspect of "smoke." PMC resulted in a twofold increase in the valve area irrespective of the method of evaluation used (2 cm2 after vs 1.05 before; p < 0.0001). Severe mitral regurgitation occurred in 3 patients who were operated on within 3 months after PMC. Left atrial spontaneous contrast was noted before the procedure in 53 patients (65%). Multivariate analysis showed left atrial size and cardiac index to be predictive factors of its presence (both p < 0.05). At early post-PMC investigation, the incidence of contrast was 50%, and at 6 months, only 28%. Sinus rhythm appeared to be the only independent predictive factor of the disappearance of contrast by multivariate analysis. In patients in atrial fibrillation, the prevalence of spontaneous contrast was 100% before PMC, 91% at early post-PMC investigation (p = NS), and 89% at the late study (p = NS); the rates were 51, 34 (p < 0.005) and 4% (p < 0.0001), respectively, in patients in sinus rhythm.(ABSTRACT TRUNCATED AT 250 WORDS)

Early assessment by transesophageal echocardiography of left atrial appendage function after percutaneous mitral commissurotomy.

Thirty-seven consecutively admitted patients with severe mitral stenosis underwent percutaneous mitral commissurotomy with a transthoracic and biplane or multiplane transesophageal echocardiographic examination before and between 24 and 48 hours after percutaneous mitral commissurotomy. Thirty patients (81%) were in sinus rhythm and 7 were in atrial fibrillation. Left atrial appendage (LAA) function was evaluated in both the transverse and the longitudinal planes by planimetry and pulsed Doppler echocardiographic interrogation at the LAA outlet. Percutaneous mitral commissurotomy resulted in a twofold increase in mitral valve area, and no severe mitral regurgitation occurred. With use of the planimetry method, there was no significant improvement in LAA ejection fraction, except in the transverse plane for patients in sinus rhythm (p = 0.03). With use of Doppler method, 3 distinct flow patterns were observed before the procedure: a "sinus pattern" in patients in sinus rhythm, and a "fibrillatory pattern" (n = 3) or a "no-flow pattern" (n = 4) in patients in atrial fibrillation. After commissurotomy, there was a marked increase in LAA peak Doppler velocity (+62%) and in LAA velocity time integral (+31%). Of the 4 patients in atrial fibrillation with a no-flow pattern, 2 had recovery of a typical effective fibrillatory flow pattern after the procedure. The increase in peak Doppler velocity after commissurotomy was related to the decrease or regression in left atrial spontaneous echo contrast, and correlated with the increase in mitral valve area, the decrease in tranmitral pressure gradient, and the increase in cardiac index; improvement in valve function after successful percutaneous mitral commissurotomy is associated with early improvement in LAA function.

Late results of percutaneous mitral commissurotomy for calcific mitral stenosis.

The aim of this study was to assess late results of percutaneous mitral commissurotomy (PMC) in calcific mitral stenosis and to identify predictors to improve patient selection. We analyzed 422 patients who underwent PMC for calcific mitral stenosis. The extent of calcium was graded from 1 to 4 by fluoroscopy: 227 patients (53%) were graded 1, 125 (30%) graded 2, 55 graded 3 (13%), and 15 graded 4 (4%). The procedure failed in 15 patients, used a single balloon in 11, a double balloon in 126, and the Inoue balloon in 270. In-hospital mortality was 1.2%. Good immediate results (valve area >/=1.5 cm(2) without mitral regurgitation >2/4), were obtained in 321 patients (76%). Multivariate analysis identified 5 predictors of good immediate results: a younger age (p = 0.0004), a lesser degree of stenosis (p = 0.0005), a smaller extent of calcium (p = 0.04), the use of the Inoue balloon (p = 0.015), and a larger effective balloon dilating area (p = 0.006). Good functional results, defined as survival with no further intervention and in New York Heart Association class I or II, were 36 +/- 4% at 8 years. The predictors of good functional results after good immediate results were a younger age (p = 0.04), a lower pre-PMC New York Heart Association class (p <0.0001), sinus rhythm (p = 0.0006), a smaller extent of calcium (p = 0.02), and a lower gradient after PMC (p <0.0001). Despite a frequent deterioration on follow-up after PMC for calcific mitral stenosis, the predictive analysis suggests that PMC may be useful in deferring surgery in selected patients with mild to moderate calcific deposits, who have otherwise favorable characteristics.

"Rescue" abciximab for complicated percutaneous transluminal coronary angioplasty.

We studied the in-hospital outcome of 138 consecutive patients who received abciximab as a "rescue" intervention for complicated coronary angioplasty in a high-risk clinical setting. "Rescue" treatment with abciximab was associated with clinical and angiographic success rates of 83% and 84%, respectively, whereas the risk of bleeding was higher in patients of low body weight.
